  4. Ethics in construction project briefing.

    PubMed

    Fellows, Richard; Liu, Anita; Storey, Colin

    2004-04-01

    The research reported in this paper set out to investigate ethics in the initial stages of construction projects. Briefing is the first real contact stage between the commissioner (client/employer) of a project--at this stage a potential project--and those involved in project realization--the designers and, subsequently, the constructors. It is well known that early decisions are of greatest impact and so, the importance of the initial contacts, communications and consequent decisions are paramount. Different project participants are known to pursue individual objectives to varying degrees as well as possessing different perspectives and perceptions and operating/behaving in different ways. Hence, determination of the appropriate form, content etc. of a project is, inevitably, a matter of exercising value judgements and compromises and so, involves ethical considerations. A case study of a project through the briefing stage is reported and analysed, from initial contacts to scheme approval. It is apparent that a number of ethical concerns are manifest through the various actions of the major participants.

  5. The ITER project construction status

    2015-10-01

    The pace of the ITER project in St Paul-lez-Durance, France is accelerating rapidly into its peak construction phase. With the completion of the B2 slab in August 2014, which will support about 400 000 metric tons of the tokamak complex structures and components, the construction is advancing on a daily basis. Magnet, vacuum vessel, cryostat, thermal shield, first wall and divertor structures are under construction or in prototype phase in the ITER member states of China, Europe, India, Japan, Korea, Russia, and the United States. Each of these member states has its own domestic agency (DA) to manage their procurements of components for ITER. Plant systems engineering is being transformed to fully integrate the tokamak and its auxiliary systems in preparation for the assembly and operations phase. CODAC, diagnostics, and the three main heating and current drive systems are also progressing, including the construction of the neutral beam test facility building in Padua, Italy. The conceptual design of the Chinese test blanket module system for ITER has been completed and those of the EU are well under way. Significant progress has been made addressing several outstanding physics issues including disruption load characterization, prediction, avoidance, and mitigation, first wall and divertor shaping, edge pedestal and SOL plasma stability, fuelling and plasma behaviour during confinement transients and W impurity transport. Further development of the ITER Research Plan has included a definition of the required plant configuration for 1st plasma and subsequent phases of ITER operation as well as the major plasma commissioning activities and the needs of the accompanying R&D program to ITER construction by the ITER parties.

    Marzouk, Mohamed M; El-Rasas, Tarek I

    2014-01-01

    Construction delays are common problems in civil engineering projects in Egypt. These problems occur frequently during project life-time leading to disputes and litigation. Therefore, it is essential to study and analyze causes of construction delays. This research presents a list of construction delay causes retrieved from literature. The feedback of construction experts was obtained through interviews. Subsequently, a questionnaire survey was prepared. The questionnaire survey was distributed to thirty-three construction experts who represent owners, consultants, and contractor's organizations. Frequency Index, Severity Index, and Importance Index are calculated and according to the highest values of them the top ten delay causes of construction projects in Egypt are determined. A case study is analyzed and compared to the most important delay causes in the research. Statistical analysis is carried out using analysis of variance ANOVA method to test delay causes, obtained from the survey. The test results reveal good correlation between groups while there is significant difference between them for some delay causes and finally roadmap for prioritizing delay causes groups is presented.

  15. Construction Cost Analysis : Residential Construction Demonstration Project Cycle II.

    SciTech Connect

    Barnett, Cole; Thor, Philip W.

    1990-06-01

    The Residential Construction Demonstration Project (RCDP) is designed to demonstrate new residential building techniques and product innovations which advance the stage-of-the-art in constructing energy-efficient electrically heated residences. A secondary purpose is to obtain documented cost and energy savings data from which to make accurate assessments of the cost-effectiveness of various conservation innovations. The project solicits participation of regional homebuilders by offering them financial incentives for constructing homes to the Model Conservation Standards (MCS) and including at least one innovation.'' The innovations are determined by BPA and the States prior to construction and represent construction techniques or energy saving products that might reduce the cost of building MCS homes, or expand the options available to builders in achieving MCS levels of energy efficiency in homes. Besides covering some of the additional risk for employing the innovation, the incentive payment guarantees that builders will provide certain amounts of information regarding the cost and acceptability of building the homes. In addition, an incentive is paid to homeowners for their participation in data collection efforts following construction. Several one-time'' tests were performed on the houses and homeowners were required to report energy consumption and temperature data on a weekly basis for approximately 18 months. BPA and the States compile the information obtained from the builders and homeowners. Access to this data is provided for the purpose of analyzing the cost and performance of the RCDP homes, as well as understanding the value of the various innovations that are tested. 25 tabs., 4 figs.

    Disher, J. H.

    1978-01-01

    The paper discusses briefly some broad plans for developing the technology needed for large construction projects in space ranging from orbiting solar power stations to large communications antennas. Space construction classes include assembly of modules, deployment of compacted structures, assembly of passive preformed pieces, and fabrication of structures from sheet stock. Technological areas related to structural concepts include (1) analyses for prediction of structural behavior, structural/control interaction, electromagnetic and control performance, and integrated design development; (2) electronics for signal conditioning and data acquisition, power distribution, and signal channel interference and multipaction; (3) concepts for shape control, attitude/pointing control, and orbital transfer and station keeping; and (4) materials and techniques for 30-year dimensional stable composites, thermal control, thin-lightweight structural alloys, and material joining in space. The concept of a power module for the construction operations is discussed along with a concept for a habitability module.

  17. Projection methods for quantum channel construction

    NASA Astrophysics Data System (ADS)

    Drusvyatskiy, Dmitriy; Li, Chi-Kwong; Pelejo, Diane Christine; Voronin, Yuen-Lam; Wolkowicz, Henry

    2015-08-01

    We consider the problem of constructing quantum channels, if they exist, that transform a given set of quantum states to another such set . In other words, we must find a completely positive linear map, if it exists, that maps a given set of density matrices to another given set of density matrices, possibly of different dimension. Using the theory of completely positive linear maps, one can formulate the problem as an instance of a positive semidefinite feasibility problem with highly structured constraints. The nature of the constraints makes projection-based algorithms very appealing when the number of variables is huge and standard interior-point methods for semidefinite programming are not applicable. We provide empirical evidence to this effect. We moreover present heuristics for finding both high-rank and low-rank solutions. Our experiments are based on the method of alternating projections and the Douglas-Rachford reflection method.

    Kuchta, Dorota; Ptaszyńska, Ewa

    2017-07-01

    The paper contains fuzzy based risk register used to identify risks which appear in construction projects and to assess their attributes. Risk is considered here as a possible event with negative consequences for the project [4]. We use different risk attributes in the proposed risk register. Values of risk attributes are generated by using fuzzy numbers. Specific risk attributes have different importance for project managers of construction projects. To compare specific risk attributes we use methods of fuzzy numbers ranking. The main strengths of the proposed concept in managing construction projects are also presented in the paper.

    Zentralmotorische Lähmungen durch Schädigungen im Hirn oder Rückenmark stellen weltweit ein großes sozialmedizinisches Problem dar. In Deutschland treten mehr als 250.000 neue Schlaganfälle pro Jahr auf. Zudem leben in Deutschland mehr als 40.000 Menschen mit Querschnittlähmung. Dazu kommen Patienten mit Schädel-Hirn-Trauma, Zerebralparesen, Multipler Sklerose, Parkinson oder Entzündungen und Tumoren des zentralen Nervensystems. Solche zentralmotorische Pathologien können durch manuelle oder automatisierte Bewegungstherapien erfolgreich behandelt werden. Dabei wird durch ein häufiges, repetitives Bewegen von Körpersegmenten die Lern- und Anpassungsfähigkeit des Gehirns und Rückenmarks genutzt. Ist eine Heilung oder Behandlung nicht mehr möglich, so können zahlreiche Techniken dazu beitragen, Bewegungsfunktionen zu unterstützen, so dass die Patienten alltägliche Aktivitäten normal ausführen können und in die Gesellschaft reintegriert werden.

    If you are the lead person during a project, it is your responsibility to follow-up on every detail and task involved to guarantee overall success. Team members look to you as the example and as the communicator. Although other people may fail to accomplish their tasks, you must have the ability and energy to push the issue to completion without losing your cool or throwing your hands up. Projects usually require the coordination of multiple issues, tasks, and personnel. The process can be rewarding, or it can be your worst nightmare. Make it fun, but keep it organized. Communicate properly, and design each project process to fit the project needs.

    2013-01-01

    Exploring the impact of the type of project coalition on types of flexibility by analyzing considered and exercised flexibilities in separated and integrated project coalitions in the design and construction phase and the operations and maintenance phase of a healthcare construction project. Flexibility in healthcare construction projects is increasingly needed in order to deal with growing uncertainties. Until now, little research has been carried out on how and to what extent flexibility is incorporated in different types of project coalitions chosen by healthcare organizations. An exploratory survey was conducted among health organizations in both cure and care. Questions were asked on the position of the real estate department within the organization, the type of project coalitions chosen and the rationale behind this choice, and the extent to which flexibility in terms of a real option was considered and to what extent it had been exercised in a project coalition. Integrated project coalitions pay more attention to flexibility in advance in both the process and the product, but exercise them to a lesser extent than separated project coalitions. The economic feasibility of real options is higher in integrated project coalitions. The study shows that real options thinking is already incorporated in real estate management of healthcare organizations, although more flexibility is considered in advance of the project than is actually realized during and after construction.

    PubMed

    Brugge, D; Dhar, A

    2008-01-01

    Few studies have been made of the impact of major construction on the health of nearby residents. We conducted a feasibility study in one zip code (02111; Chinatown, Boston, MA, USA) in which four large buildings (20-30 stories) were built between 1999 and 2004 and adjacent to which a major highway construction project was in progress. Information about major construction project start and end dates were obtained from a variety of sources. Three sets of health data--emergency department and mortality-were obtained from the Massachusetts Department of Public Health for the years of 1998 - 2004. We used ICD-9 and ICD-10 disease codes to aggregate selected pulmonary and cardiac-related categories that could reasonably be expected to be aggravated by air pollution released from construction sites, including diesel and dust, and noise and vibration. We propose that larger-scale studies are possible and needed using approaches similar to ours.

    NASA Technical Reports Server (NTRS)

    1979-01-01

    Three project systems are defined and summarized. The systems are: (1) a Solar Power Satellite (SPS) Development Flight Test Vehicle configured for fabrication and compatible with solar electric propulsion orbit transfer; (2) an Advanced Communications Platform configured for space fabrication and compatible with low thrust chemical orbit transfer propulsion; and (3) the same Platform, configured to be space erectable but still compatible with low thrust chemical orbit transfer propulsion. These project systems are intended to serve as configuration models for use in detailed analyses of space construction techniques and processes. They represent feasible concepts for real projects; real in the sense that they are realistic contenders on the list of candidate missions currently projected for the national space program. Thus, they represent reasonable configurations upon which to base early studies of alternative space construction processes.

    2017-09-01

    The construction industry is well-known for producing waste detrimental to the environment, and its impacts have increased with the development process of cities. Although there are several studies focused on the environmental impact of residential and commercial buildings, less knowledge is available regarding decreasing construction waste (CW) generation in urban infrastructure projects. This study presents best practices to reduce waste in the said projects, stressing the role of decision-making in the design stage and the effective management of construction processes in public sector. The best practices were identified from literature review, document analysis in 14 projects of urban infrastructure, and both qualitative and quantitative survey with 18 experts (architects and engineers) playing different roles on those projects. The contributions of these research are: (i) the identification of the main building techniques related to the urban design typologies analyzed; (ii) the identification of cause-effect relationships between the design choices and the CW generation diagnosis; (iii) the proposal of a checklist to support the decision-making process, that can be used as a control and evaluation instrument when developing urban infrastructure designs, focused on the construction waste minimization (CWM).

  13. UTILIZATION OF THREE-DIMENSIONAL INFORMATION IN ROAD CONSTRUCTION PROJECTS

    NASA Astrophysics Data System (ADS)

    Kubota, Satoshi

    In this research targeting road construction projects, schemes were investigated for utilizing three-dimensional (3D) data distributed in accordance with ISO (Internatio nal Organization for Standardization) and produced by 3D computer-aided design (CAD) software based on the concept of product data models. First, existing literature was classified by work stage as the context for utilizing 3D data. Next, the establishment of standards for exchanging 3D data, revising relevant systems, constructing road data models, realizing work process models, developing 3D CAD engines, and providing 3D data utilization environments are discussed, both as measures that should be undertaken and as future research topics for promoting the utilization of 3D data. Finally, the potential for utilizing 3D data in road construction projects by local government is examined, and the items to be implemented for this purpose are summarized.

  14. Identification of critical factors affecting flexibility in hospital construction projects.

    PubMed

    Olsson, Nils E O; Hansen, Geir K

    2010-01-01

    This paper analyzes the dynamics relating to flexibility in a hospital project context. Three research questions are addressed: (1) When is flexibility used in the life cycle of a project? (2) What are the stakeholders' perspectives on project flexibility? And (3) What is the nature of the interaction between flexibility in the process of a project and flexibility in terms of the characteristics of a building? Flexibility is discussed from both a project management point of view and from a hospital architecture perspective. Flexibility in project life cycle and from a stakeholder perspective is examined, and the interaction between flexibility in scope lock-in and building flexibility is investigated. The results are based on case studies of four Norwegian hospital projects. Information relating to the projects has been obtained from evaluation reports, other relevant documents, and interviews. Observations were codified and analyzed based on selected parameters that represent different aspects of flexibility. One of the cases illustrates how late changes can have a significant negative impact on the project itself, contributing to delays and cost overruns. Another case illustrates that late scope lock-in on a limited part of the project, in this case related to medical equipment, can be done in a controlled manner. Project owners and users appear to have given flexibility high priority. Project management teams are less likely to embrace changes and late scope lock-in. Architects and consultants are important for translating program requirements into physical design. A highly flexible building did not stop some stakeholders from pushing for significant changes and extensions during construction.

    SciTech Connect

    1994-12-01

    This Public Design Report describes the 1000 ton per day ENCOAL mild coal gasification demonstration plant now in operation at the Buckskin Mine near Gillette, Wyoming. The objective of the project is to demonstrate that the proprietary Liquids From Coal (LFC) technology can reliably and economically convert low Btu PRB coal into a superior, high-Btu solid fuel (PDF), and an environmentally attractive low-sulfur liquid fuel (CDL). The Project`s plans also call for the production of sufficient quantities of PDF and CDL to permit utility companies to carry out full scale burn tests. While some process as well as mechanical design was done in 1988, the continuous design effort was started in July 1990. Civil construction was started in October 1990; mechanical erection began in May 1991. Virtually all of the planned design work was completed by July 1991. Most major construction was complete by April 1992 followed by plant testing and commissioning. Plant operation began in late May 1992. This report covers both the detailed design and initial construction aspects of the Project.

    2005-01-01

    This paper aims at providing cost-effective safety measures to protect construction workers in highway work zones, based on real data. Two types of accidents that occur in work zones were: (a) construction work area accidents, and (b) traffic accidents involving construction worker(s). A detailed analysis of work zone accidents involving 36 fatalities and 3,055 severe injuries to construction workers on New York State Department of Transportation (NYSDOT) construction projects from 1990 to 2001 established that five accident types: (a) Struck/Pinned by Large Equipment, (b) Trip or Fall (elevated), (c) Contact w/Electrical or Gas Utility, (d) Struck-by Moving/Falling Load, and (e) Crane/Lift Device Failure accounted for nearly 96% of the fatal accidents, nearly 63% of the hospital-level injury accidents, and nearly 91% of the total costs. These construction work area accidents had a total cost of $133.8 million. Traffic accidents that involve contractors' employees were also examined. Statistical analyses of the traffic accidents established that five traffic accident types: (a) Work Space Intrusion, (b) Worker Struck-by Vehicle Inside Work Space, (c) Flagger Struck-by Vehicle, (d) Worker Struck-by Vehicle Entering/Exiting Work Space, and (e) Construction Equipment Struck-by Vehicle Inside Work Space accounted for nearly 86% of the fatal, nearly 70% of the hospital-level injury and minor injury traffic accidents, and $45.4 million (79.4%) of the total traffic accident costs. The results of this paper provide real statistics on construction worker related accidents reported on construction work zones. Potential preventions based on real statistics have also been suggested. The ranking of accident types, both within the work area as well as in traffic, will guide the heavy highway contractor and owner agencies in identifying the most cost effective safety preventions.

    In Today’s construction industry, to achieve a greater advantage over the firms, success of each project and efficiency is required. Effective Project Management overcomes these types of challenges. This study identifies the success factors which are important for project management in construction project success. From the literature review, 26 factors were found to be critical. Project managers, construction managers, civil engineers, contractors and site engineers were the respondents. After analyzing the data in SPSS software, the dominant factors from the regression analysis are top management support, competent project team, abilities to solve problems, realistic cost and time estimates, information/communication, competency of the project manager are the 6 factors out of 12 in 26 factors. Effective communication between stakeholders got highest priority and client involvement, good leadership, clarity of project goals got second priority. Informal communication gives better results compared to formal communications like written formats. To remove communication barrier with the stakeholders, informal communication like speaking face-to-face with the language this fits for the stakeholders.

    2009-11-01

    Decisions made during the project construction phase may bear considerable impacts on the success of transport projects and undermine the ex-ante project evaluation. An innovative and holistic approach has been taken to assess and address this issue by (a) examining the decision process and procedure during project construction, through a field survey, (b) assessing the impact of decisions made during construction on respective transport project and, finally, (c) developing a quality monitoring framework model which links decisions made during the project implementation (construction) phase with the ex-ante and ex-post project evaluations. The framework model is proposed as a guiding and support tool for decision makers.

    Yang, Zhang

    Because the disputes and case facts of construction project contracts are intricate, there are many new conditions and problems involved in application of law, it's very difficult to dispose in the judicial practice with the difference in judicial theories and understanding spirit of the laws, and the juridical criterions of judgment are not unified in the courts of various regions. As judicial organs, people's courts should keep pace with the times, take precautions, and do well investigations and researches on such application of law in such cases in order to give full play to the judicial function, to safeguard the lawful rights and interests of disadvantaged groups and to promote the sustained, rapid and sound development of real estate market.

  8. Proton therapy construction projects in the United States

    SciTech Connect

    Alonso, J.R.

    1992-11-01

    Proton and heavy-ion radiation therapy has been taking place now for 40 years, at many accelerator laboratories around the world, essentially all of these centers built originally for physics research. The high degree of promise shown for using these particles for treating and curing cancer has stimulated the medical community to look seriously at building dedicated accelerator facilities in a hospital setting, where more rapid progress can be made in clinical research, and development of effective treatments with these beams. In the United States, the first such facility, at the Loma Linda University Medical Center, has been in operation now for two years, and is currently treating a total of 35 to 40 patients per day. Two new projects are being designed at present, one at the Massachusetts General Hospital in Boston, Massachusetts, the second a joint project of the Lawrence Berkeley Laboratory and the University of California at Davis Medical Center in Sacramento, California. This paper will discuss accelerator and beam characteristics relevant to the proton-therapy application, and will present performance and operations characteristics for the Loma Linda facility, as well as details of the plans, process and progress towards construction of the new facilities in Boston and Sacramento.

  16. Decisive management in selecting locations for development of construction projects

    NASA Astrophysics Data System (ADS)

    Szafranko, E.; Pawłowicz, J. A.

    2017-08-01

    The location of an investment project is one of the most important decisions in the construction and land development business. The shape of a new building and aspects of its future use depend on making a good choice of a land plot where it will be constructed. There are many characteristics involved descriptions of land available for development. On the one hand, different buildings (with different envisaged use) fit differently to a given location. Residential homes, for example, require a location which will ensure a peaceful lifestyle, with places for walks and recreation, situated in a relatively quite setting. On the other hand, close proximity to schools, shops or a health clinic is another important consideration. Industrial buildings should be localized so as not to be a nuisance to others, and their location should facilitate efficient transport of raw materials and ready products. Yet other requirements are defined for public buildings. It is therefore evident that the characteristics included in an evaluation of the location of a planned building can be highly diverse and their diversity makes the evaluation difficult. Selection of a location can be supported by a variety of methods. For instance, an evaluation can rely on assigning points which indicate the fulfillment of certain criteria. This approach generates a complex evaluation in the form of tables and maps of usefulness. Another possibility is to make an assessment of the criteria that a given land parcels should satisfy in order to develop a specific type of a building. Having combined these two sets of information, we can create a system or a model for the management of land resources, which will easily help to support decision making processes pertaining to the choice of a location. This article shows a model approach for a specific building.

    1981-12-01

    The study evaluates methodology employed for the projection of labor demand at, and worker migration to, nuclear power plant construction sites. In addition, suggestions are offered as to how this projection methodology might be improved. The study focuses on projection methodologies which forecast either construction worker migration or labor requirements of alternative types of construction activity. Suggested methodological improvements relate both to institutional factors within the nuclear power plant construction industry, and to a better use of craft-specific data on construction worker demand/supply. In addition, the timeliness and availability of the regional occupational data required to support, or implement these suggestions are examined.

    2016-08-01

    Nowadays, construction industry particularly in Malaysia struggle in achieving status of eminent time management for construction project. Project managers have a great responsibility to keep the project success under time of project completion. However, studies shows that delays especially in Malaysian construction industry still unresolved due to weakness in managing the project. In addition, quality of time management on construction projects is generally poor. Due to the progressively extended delays issue, time performance becomes an important subject to be explored to investigate delay factors. The method of this study is review of literature towards issues in construction industry which affecting time performance of project in general by focusing towards process involved for project management. Based on study, it was found that knowledge, commitment, cooperation are the main criteria as an overall to manage the project into a smooth process during project execution until completion. It can be concluded that, the strength between project manager and team members in these main criteria while conducting the project towards good time performance is highly needed. However, there is lack of establishment towards factors of poor time performance which strongly related with project management. Hence, this study has been conducted to establish factors of poor time performance and its relations with project management.

    2017-07-01

    Developing countries like India require a huge infrastructure to facilitate needs of the people. Construction industry provides several opportunities to the individuals. Construction manager work is to supervise and organize the construction activities in construction projects. Now a day construction manager facing challenges. This paper aimed to study the challenges facing by the construction manager in the perception of construction professionals. 39 variables were taken from the literature review which found to be severe impact on construction managers’ performance. Construction manager, project manager and site engineers are the respondents for this survey. Using SPSS, regression analysis was done and recognized significant challenges. These challenges were classified into 5 domains. In management challenges, resource availability and allocation, risks and uncertainties existing in the project onsite, top management support and cost constraints are the most significant variables. In skills requirement of a construction manager challenges, technical skills required to learn and adapt new technology in the project, decision making and planning according to the situation in site are the most significant variables. In performance challenges, implementation of tasks according to the plan is the important variable whereas in onsite challenges, manage project risks, develop project policies and procedures are the most important.

  18. Special report on the audit of the management of Department of Energy construction projects

    SciTech Connect

    1996-11-21

    DOE`s FY 1996 budget of $18 billion included $1.1 billion for construction projects; ensuring that these projects meet bonafide existing or future DOE needs becomes increasingly important as DOE`s missions evolve and its organization changes. In 1994 and 1995, IG issued several reports expressing concerns about the construction planning process and questioned whether planned construction was necessary to meet mission needs. The reports also pointed out that DOE did not ensure that originally identified needs were still valid several years after a project`s conception. (The problems identified were at single locations.) While DOE management did not agree with all aspects of the audit reports, it canceled or downsized several projects and initiated a number of process improvements to enhance the construction planning process. Purpose of this report is to synthesize issues from these prior reports to assist management in focusing process improvement efforts to avoid construction of unneeded or oversized facilities.

    Chowdhury, Tamara

    2013-08-01

    Senior design courses are a core part of curricula across engineering and technology disciplines. Such courses offer Construction Management (CMG) students the opportunity to bring together, assimilate and apply the knowledge they have acquired over their entire undergraduate academic programme to an applied technical project. Senior or Capstone design course engages students in a real-world project, enhance leadership development, and prepare to manage and lead project teams. The CMG programme's multidisciplinary approach at Alabama A&M University, combines essential components of construction techniques with concepts of business management to develop technically qualified individuals for responsible management roles in the design, construction and operation of major construction projects. This paper analyses the performance of the students and improvement due to the interaction with the faculty advisors and industrial panel during the two semester Capstone project. The results of this Capstone sequence have shown a continuous improvement of student performance.

  1. Identification of Tools and Techniques to Enhance Interdisciplinary Collaboration During Design and Construction Projects.

    PubMed

    Keys, Yolanda; Silverman, Susan R; Evans, Jennie

    2016-01-01

    The purpose of this study was to collect the perceptions of design professionals and clinicians regarding design process success strategies and elements of interprofessional engagement and communication during healthcare design and construction projects. Additional objectives were to gather best practices to maximize clinician engagement and provide tools and techniques to improve interdisciplinary collaboration for future projects. Strategies are needed to enhance the design and construction process and create interactions that benefit not only the project but the individuals working to see its completion. Meaningful interprofessional collaboration is essential to any healthcare design project and making sure the various players communicate is a critical element. This was a qualitative study conducted via an online survey. Respondents included architects, construction managers, interior designers, and healthcare personnel who had recently been involved in a building renovation or new construction project for a healthcare facility. Responses to open-ended questions were analyzed for themes, and descriptive statistics were used to provide insight into participant demographics. Information on the impressions, perceptions, and opportunities related to clinician involvement in design projects was collected from nurses, architects, interior designers, and construction managers. Qualitative analysis revealed themes of clinician input, organizational dynamics, and a variety of communication strategies to be the most frequently mentioned elements of successful interprofessional collaboration. This study validates the need to include clinician input in the design process, to consider the importance of organizational dynamics on design team functioning, and to incorporate effective communication strategies during design and construction projects.

  2. A decision support system framework to improve design-construction integration and project performance on public sector underground utility projects

    NASA Astrophysics Data System (ADS)

    Gehrig, Gary Bruce

    One of the noted difficulties with the traditional public works project development process is the lack of integration and sharing of information between engineering and construction entities that results in a decrease in project performance. To improve project performance on public sector underground utility projects, the research develops a decision support system framework that enhances the exchange and integration of relevant information and knowledge between entities on such projects by incorporating a lessons-learned database to document, organize and disseminate lessons-learned on a project. To identify the critical activities within the project development process that could be linked to the decision support system, the Integration Definition for Functioning Modeling (IDEFO) technique was used to create a representative model of the public works project development process. The resultant model demonstrated the repeatable nature of the process both across project phases and from project-to-project and identified the decision-making activities of generating and evaluating alternatives as key opportunities for construction-related input that could be linked to a decision support system. An inspection of current industry practices was conducted through interviews with knowledgeable industry sources to determine the scope of the decision support system framework. Results revealed the type of critical decisions on underground utility projects that could benefit from construction-related input and identified the documentation of lessons-learned as a major industry weakness. A prototype decision support system incorporating a lessons-learned database was developed and the framework integrated into common project management reporting mechanisms found in the industry. The actual decision-maker can retrieve lessons-learned according to predetermined categories of critical decisions, compare and evaluated retrieved alternatives, and document the rationale behind the

    2016-08-01

    Currently, rapid development of information technology has provided new opportunities to organisation toward increasing the effectiveness of collaboration and teamwork management. Thus the virtual team approach has been implemented in numerous of field. However, there is limited study of virtual team in construction project management. Currently IBS project is still based on traditional construction process which is isolation team working environment. Therefore this approach has been declared as a main barrier to ensure cooperative working relation in term of communication and information in between project stakeholders. Thus, this paper through literature review is attempted to present a discussion of the virtual team approach toward IBS project in developing effective team communication during construction project.

    Friesel, D. L.; Lee, S. Y.

    1997-05-01

    Construction of a 2.24 T-m, rapid-cycling booster synchrotron is nearing completion at IUCF. The synchrotron is designed to accelerate protons to 220 MeV and will replace the IUCF isochronous cyclotrons as an injector of polarized light ion beams into the 3.6 T-m electron-cooled storage ring. CIS (Cooler Injector Synchrotron), with a circumference of 1/5th the Cooler ring, will fill the Cooler to about 10^11 protons via ``boxcar" stacking in a few seconds for research. The compact booster design, which can accelerate protons to energies between 60 and 220 MeV, is also well suited for use in proton therapy applications. At 28 months into the construction program, all major ring elements (dipoles, quads, injector linac, RF system) are fabricated, assembled, installed and in some cases, commissioned. Ring beam injection and ramping studies are scheduled to start in May, 1997 and Cooler injection studies are planned for late 1997. The booster design properties, component commissioning results and construction completion schedule will be summarized.

  7. An innovative time-cost-quality tradeoff modeling of building construction project based on resource allocation.

    PubMed

    Hu, Wenfa; He, Xinhua

    2014-01-01

    The time, quality, and cost are three important but contradictive objectives in a building construction project. It is a tough challenge for project managers to optimize them since they are different parameters. This paper presents a time-cost-quality optimization model that enables managers to optimize multiobjectives. The model is from the project breakdown structure method where task resources in a construction project are divided into a series of activities and further into construction labors, materials, equipment, and administration. The resources utilized in a construction activity would eventually determine its construction time, cost, and quality, and a complex time-cost-quality trade-off model is finally generated based on correlations between construction activities. A genetic algorithm tool is applied in the model to solve the comprehensive nonlinear time-cost-quality problems. Building of a three-storey house is an example to illustrate the implementation of the model, demonstrate its advantages in optimizing trade-off of construction time, cost, and quality, and help make a winning decision in construction practices. The computational time-cost-quality curves in visual graphics from the case study prove traditional cost-time assumptions reasonable and also prove this time-cost-quality trade-off model sophisticated.

    2013-09-01

    The inherent and unique risks on construction projects quite often present key challenges to contractors. Health and safety risks are among the most significant risks in construction projects since the construction industry is characterized by a relatively high injury and death rate compared to other industries. In construction project management, safety risk assessment is an important step toward identifying potential hazards and evaluating the risks associated with the hazards. Adequate prioritization of safety risks during risk assessment is crucial for planning, budgeting, and management of safety related risks. In this paper, a safety risk assessment framework is presented based on the theory of cost of safety (COS) model and the analytic hierarchy process (AHP). The main contribution of the proposed framework is that it presents a robust method for prioritization of safety risks in construction projects to create a rational budget and to set realistic goals without compromising safety. The framework provides a decision tool for the decision makers to determine the adequate accident/injury prevention investments while considering the funding limits. The proposed safety risk framework is illustrated using a real-life construction project and the advantages and limitations of the framework are discussed.

    2017-08-01

    As the main body of power grid operation, county-level power supply enterprises undertake an important emission to guarantee the security of power grid operation and safeguard social power using order. The optimization of grid construction projects has been a key issue of power supply capacity and service level of grid enterprises. According to the actual situation of power grid construction project optimization of county-level power enterprises, on the basis of qualitative analysis of the projects, this paper builds a Bi-level programming model based on quantitative analysis. The upper layer of the model is the target restriction of the optimal portfolio; the lower layer of the model is enterprises’ financial restrictions on the size of the enterprise project portfolio. Finally, using a real example to illustrate operation proceeding and the optimization result of the model. Through qualitative analysis and quantitative analysis, the bi-level programming model improves the accuracy and normative standardization of power grid enterprises projects.

  5. Relational approach in managing construction project safety: a social capital perspective.

    PubMed

    Koh, Tas Yong; Rowlinson, Steve

    2012-09-01

    Existing initiatives in the management of construction project safety are largely based on normative compliance and error prevention, a risk management approach. Although advantageous, these approaches are not wholly successful in further lowering accident rates. A major limitation lies with the approaches' lack of emphasis on the social and team processes inherent in construction project settings. We advance the enquiry by invoking the concept of social capital and project organisational processes, and their impacts on project safety performance. Because social capital is a primordial concept and affects project participants' interactions, its impact on project safety performance is hypothesised to be indirect, i.e. the impact of social capital on safety performance is mediated by organisational processes in adaptation and cooperation. A questionnaire survey was conducted within Hong Kong construction industry to test the hypotheses. 376 usable responses were received and used for analyses. The results reveal that, while the structural dimension is not significant, the mediational thesis is generally supported with the cognitive and relational dimensions affecting project participants' adaptation and cooperation, and the latter two processes affect safety performance. However, the cognitive dimension also directly affects safety performance. The implications of these results for project safety management are discussed. Copyright © 2011 Elsevier Ltd.

    Hatipkarasulu, Yilmaz; Gill, James H

    2004-04-01

    The increasing number of companies providing internet services and auction tools helped popularize the online reverse auction trend for purchasing commodities and services in the last decade. As a result, a number of owners, both public and private, accepted the online reverse auctions as the bidding technique for their construction projects. Owners, while trying to minimize their costs for construction projects, are also required to address their ethical responsibilities to the shareholders. In the case of online reverse auctions for construction projects, the ethical issues involved in the bidding technique directly reflects on the owner's ethical and social responsibilities to their shareholders. The goal of this paper is to identify the shareholder ethics and responsibilities in online reverse auctions for construction projects by analyzing the ethical issues for the parties involved in the process. The identification of the ethical issues and responsibilities requires clear definition and understanding of professional ethics and the roles of the involved parties. In this paper, first, the concept of professional ethics and social responsibility is described in a general form. To illustrate the ethical issues and responsibilities, a sample case of bidding for a construction project using online reverse auction techniques is presented in which the shareholders were actively involved in questioning the ethical issues. The issues involved in the bidding process and their reflection on the shareholder responsibilities are described and analyzed for each stage of the process. A brief discussion of the overall process is also included to address the general ethical issues involved in online reverse auctions.

  7. The S-curve for forecasting waste generation in construction projects.

    2016-10-01

    Forecasting construction waste generation is the yardstick of any effort by policy-makers, researchers, practitioners and the like to manage construction and demolition (C&D) waste. This paper develops and tests an S-curve model to indicate accumulative waste generation as a project progresses. Using 37,148 disposal records generated from 138 building projects in Hong Kong in four consecutive years from January 2011 to June 2015, a wide range of potential S-curve models are examined, and as a result, the formula that best fits the historical data set is found. The S-curve model is then further linked to project characteristics using artificial neural networks (ANNs) so that it can be used to forecast waste generation in future construction projects. It was found that, among the S-curve models, cumulative logistic distribution is the best formula to fit the historical data. Meanwhile, contract sum, location, public-private nature, and duration can be used to forecast construction waste generation. The study provides contractors with not only an S-curve model to forecast overall waste generation before a project commences, but also with a detailed baseline to benchmark and manage waste during the course of construction. The major contribution of this paper is to the body of knowledge in the field of construction waste generation forecasting. By examining it with an S-curve model, the study elevates construction waste management to a level equivalent to project cost management where the model has already been readily accepted as a standard tool.

  1. Hanford's 100-HX Pump and Treat Project - a Successful Blend of Science, Technology, Construction, and Project Management - 12412

    SciTech Connect

    Albin, Kenneth A.; Bachand, Marie T.; Biebesheimer, Fred H.; Neshem, Dean O.; Smoot, John L.

    2012-07-01

    CH2M Hill Plateau Remediation Company (CHPRC) recently completed construction and start-up of the $25 million 100-HX Groundwater Pump and Treat Project for the Department of Energy (DOE) at its Hanford Reservation site in Washington State. From the onset, the 100-HX Project Leadership Team was able to successfully blend the science and technology of a state-of-the-art groundwater pump and treat system with the principles, tools, and techniques of traditional industrial-type construction and project management. From the 1940's through most of the 1980's, the United States used the Hanford Site to produce nuclear material for national defense at reactor sites located along the Columbia River. While the reactors were operational, large volumes of river water were treated with sodium dichromate (to inhibit corrosion of the reactor piping) and used as a coolant for the reactors. After a single pass through the reactor and before being discharged back to the river, the coolant water was sent to unlined retention basins to cool and to allow the short-lived radioactive contaminants to decay. As a result of these operations, hexavalent chromium was introduced to the vadose zone, and ultimately into the groundwater aquifer and the adjacent Columbia River. In addition, numerous leaks and spills of concentrated sodium dichromate stock solution over the lifetime of reactor operations led to higher concentrations of chromate in the vadose zone and groundwater in localized areas. As a result, the 100 Area was included in the National Priorities List sites under the Comprehensive Environmental Response Compensation and Liability Act of 1980 (CERCLA). The mission of the 100-HX Project is to significantly reduce the concentration of hexavalent chromium in the groundwater by treating up to 3.8 billion gallons (14,300 mega-liters) of contaminated water over its first nine years of operations. In order to accomplish this mission, groundwater scientists and geologists using

    2005-03-01

    Phase I of the Kissimmee River restoration project included backfilling of 12 km of canal and restoring flow through 24 km of continuous river channel. We quantified the effects of construction activities on four water quality parameters (turbidity, total phosphorus flow-weighted concentration, total phosphorus load and dissolved oxygen concentration). Data were collected at stations upstream and downstream of the construction and at four stations within the construction zone to determine if canal backfilling and construction of 2.4 km of new river channel would negatively impact local and downstream water quality. Turbidity levels at the downstream station were elevated for approximately 2 weeks during the one and a half year construction period, but never exceeded the Florida Department of Environmental Protection construction permit criteria. Turbidity levels at stations within the construction zone were high at certain times. Flow-weighted concentration of total phosphorus at the downstream station was slightly higher than the upstream station during construction, but low discharge limited downstream transport of phosphorus. Total phosphorus loads at the upstream and downstream stations were similar and loading to Lake Okeechobee was not significantly affected by construction. Mean water column dissolved oxygen concentrations at all sampling stations were similar during construction.

    1986-11-01

    In January 1986, the Becon Construction Company - an open-shop contractor based in Houston, Texas - mobilized a work force to a construction project location at the Belridge Oil Field, near Bakersfield, California. The construction craftsmen and helpers in Becon's work force were expected to improve their level of productivity as the work proceeded because of the knowledge and skills that they would acquire as a result of the repetitive nature of the work. As it was originally organized, the Becon HOTS project represented almost a pure laboratory environment in which to collect data concerning the learning effect on worker productivity as well as to statistically isolate the impact on productivity of such external factors as weather, absenteeism, turnover, and especially work methods improvement techniques and pay incentives. From the outset of the HOTS project, the project manager had established an accurate system to quantitatively measure and compare the total manhours that each crew - civil, mechanical, electrical, and prefabrication -- performed at individual HOTS construction locations. Additionally, it was initially assumed that the project manager would be relatively free to implement changes to the job site conditions involving incentive pay and work methods improvement. The subsequent effect of these changes on the productivity of separate work crews could then be evaluated in terms of measured manhours per crew per HOTS.

    The construction industry is one of the contributor toward sustainability of a country's economy. However, there are some issues that need to be faced in this industry that are including construction waste management resulting from the development activities. This issue become more serious when the industrial stakeholders especially in developing countries have lack of awareness in construction waste management practices. Some of industry stakeholders do not realize that proper waste management will increase the project performance. Therefore, waste management practices among industry stakeholders need to be improved towards better environmental quality.

    2015-01-01

    Among the recent data mining techniques available, the boosting approach has attracted a great deal of attention because of its effective learning algorithm and strong boundaries in terms of its generalization performance. However, the boosting approach has yet to be used in regression problems within the construction domain, including cost estimations, but has been actively utilized in other domains. Therefore, a boosting regression tree (BRT) is applied to cost estimations at the early stage of a construction project to examine the applicability of the boosting approach to a regression problem within the construction domain. To evaluate the performance of the BRT model, its performance was compared with that of a neural network (NN) model, which has been proven to have a high performance in cost estimation domains. The BRT model has shown results similar to those of NN model using 234 actual cost datasets of a building construction project. In addition, the BRT model can provide additional information such as the importance plot and structure model, which can support estimators in comprehending the decision making process. Consequently, the boosting approach has potential applicability in preliminary cost estimations in a building construction project.

    2009-05-01

    This study presents a GIS-based database framework used to assess aggregate terrestrial habitat impacts from multiple highway construction projects in California, USA. Transportation planners need such impact assessment tools to effectively address additive biological mitigation obligations. Such assessments can reduce costly delays due to protracted environmental review. This project incorporated the best available statewide natural resource data into early project planning and preliminary environmental assessments for single and multiple highway construction projects, and provides an assessment of the 10-year state-wide mitigation obligations for the California Department of Transportation. Incorporation of these assessments will facilitate early and more strategic identification of mitigation opportunities, for single-project and regional mitigation efforts. The data architecture format uses eight spatial scales: six nested watersheds, counties, and transportation planning districts, which were intersected. This resulted in 8058 map planning units statewide, which were used to summarize all subsequent analyses. Range maps and georeferenced locations of federally and state-listed plants and animals and a 55-class landcover map were spatially intersected with the planning units and the buffered spatial footprint of 967 funded projects. Projected impacts were summarized and output to the database. Queries written in the database can sum expected impacts and provide summaries by individual construction project, or by watershed, county, transportation district or highway. The data architecture allows easy incorporation of new information and results in a tool usable without GIS by a wide variety of agency biologists and planners. The data architecture format would be useful for other types of regional planning.

    2007-03-01

    Global ecological security becomes increasingly important with the intensive human activities. The function of ecological security is influenced by human activities, and in return, the efficiency of human activities will also be affected by the patterns of regional ecological security. Since the 1990s, China has initiated the construction of key projects "Yangtze Three Gorges Dam", "Qinghai-Tibet Railway", "West-to-East Gas Pipeline", "West-to-East Electricity Transmission" and "South-to-North Water Transfer" , etc. The interaction between these projects and regional ecological security has particularly attracted the attention of Chinese government. It is not only important for the regional environmental protection, but also of significance for the smoothly implementation of various projects aimed to develop an ecological rehabilitation system and to design a regional ecological security pattern. This paper made a systematic analysis on the types and characteristics of key project construction and their effects on the environment, and on the basis of this, brought forward the basic principles and methodology for ecological rehabilitation and security pattern design in this construction. It was considered that the following issues should be addressed in the implementation of a key project: 1) analysis and evaluation of current regional ecological environment, 2) evaluation of anthropogenic disturbances and their ecological risk, 3) regional ecological rehabilitation and security pattern design, 4) scenario analysis of environmental benefits of regional ecological security pattern, 5) re-optimization of regional ecological system framework, and 6) establishment of regional ecosystem management plan.

    As a result of increasing recognition of effective site management as the strategic approach for achieving the required performance in construction projects, this study seeks to identify the key site management practices that are requisite for construction waste minimization. A mixed methods approach, involving field study and survey research were used as means of data collection. After confirmation of construct validity and reliability of scale, data analysis was carried out through a combination of Kruskal-Wallis test, descriptive statistics and exploratory factor analysis. The study suggests that site management functions could significantly reduce waste generation through strict adherence to project drawings, and by ensuring fewer or no design changes during construction process. Provision of waste skips for specific materials and maximisation of on-site reuse of materials are also found to be among the key factors for engendering waste minimization. The result of factor analysis suggests four factors underlying on-site waste management practices with 96.093% of total variance. These measures include contractual provisions for waste minimization, waste segregation, maximisation of materials reuse and effective logistic management. Strategies through which each of the underlying measures could be achieved are further discussed in the paper. Findings of this study would assist construction site managers and other site operatives in reducing waste generated by construction activities. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Several features of solar energy space power stations are discussed. An end-to-end analysis of a system using silicon solar cells is reviewed, and the merits of construction in low earth orbit and in geosynchronous orbit are compared. A suggested space construction procedure, described in detail, would use a 'beam builder', an automated machine, to fabricate the first sublevel truss structural members from strip stock material that is stored on reels. An assembly jig would then be used to position a number of beam builders in the proper location and to support the beams as they are produced to facilitate joining them to form the final space power station structure. Space projects for evaluating the construction concept are proposed, and a possible space construction sequence is considered. Space transportation that would be required in conjunction with the space power station is described.

  13. Safety incentive and penalty provisions in Indian construction projects and their impact on safety performance.

    Hasan, Abid; Jha, Kumar Neeraj

    2013-01-01

    Safety incentive and penalty (I/P) provisions in construction contracts are one of the most common forms of I/P. Contradictory opinions on the effectiveness of these provisions have been expressed in the literature. Statistics on safety provisions were collected from 32 construction projects, which include both types of contracts - those with safety I/P provisions and those without them. Although inclusion of safety I/P provisions in contracts helps in improving the overall safety performance in construction projects, further scope for improvement still exists. Literature review and structured personal interviews, coupled with a survey based on preliminary questionnaire, revealed that successful formulation and implementation of such provisions are dependent on 25 attributes which need the attention of both clients and contractors. A questionnaire-based survey was conducted to evaluate these attributes. The six factors extracted by carrying out factor analysis are: incentive distribution method, proper labour training, special attention to risky situations, role of safety committee and sub-contractors, specialised works and safety equipments, and right form of I/P. If taken care of, these attributes have the potential to improve the safety performance in construction projects. The results would be useful to clients and contractors in implementing the safety I/P provisions and thereby improving safety performance.

  14. Exploring factors affecting owners' trust of contractors in construction projects: a case of China.

    Tai, Shuangliang; Sun, Chengshuang; Zhang, Shoujian

    2016-01-01

    It has been found that a low level of trust among members of a construction project team leads to poor performance in China. Many researchers have described the challenges, consequently advocating partnering as an attractive approach for more valuable cooperation. Because substantial investments have been poured into construction projects since the year 2000, trust research will improve the performance of construction projects and will be meaningful to the Chinese construction industry. The purpose of this paper is to investigate the attributes affecting owners' trust of contractors, to understand the potential properties of these factors, and to rank the factors in order of importance. Twenty-four attributes are identified from a literature review. Supported by qualitative reviews, a questionnaire is conducted to obtain relevant data, and 168 valid responses are obtained for data analysis. Principal component analysis (PCA) is employed to find the factor structure of the identified trust attributes. By the method of PCA, the attributes are extracted into eight factors, including interaction history, information sharing and communication, contract and institution, relation-specific investment, reputation, integrity, competence, and opportunistic behaviour. The value and originality of this paper are embodied in using PCA to understand the various attribute groupings and to illuminate trust impact factors in the Chinese context. When they understand the critical factors affecting trust better, owners and contractors can devise more appropriate strategies to improve performance.

    2015-07-01

    Urban underground transportation projects are introduced to address problems of scarce green land and traffic pollution. As construction of urban underground transportation is still in its infancy, there is no definite quantitative measurement on whether the construction is beneficial and what influences it will place on the region in China. This study intends to construct a comprehensive evaluation method for evaluating social, economic and environmental benefits of urban underground transportation projects and proposes the concept, role and principle for evaluation of environmental and economic benefits. It figures out relationship between the environment and factors of city development. It also summarizes three relevant factors, including transportation, biophysics and social economy, and works out indicators to evaluate the influence of urban underground transportation construction. Based on Contingent Valuation Method (CVM), Cost of Illness Approach (CIA), Human Capital Approach (HCA), this paper constructs 13 monetization calculation models for social, economic and environmental benefits in response to seven aspects, namely, reducing noise pollution and air pollution, using land efficiently, improving traffic safety, reducing traffic congestion, saving shipping time and minimizing transportation costs.

  19. Medial Temporal Lobe Contributions to Episodic Future Thinking: Scene Construction or Future Projection?

    PubMed

    Palombo, D J; Hayes, S M; Peterson, K M; Keane, M M; Verfaellie, M

    2016-12-01

    Previous research has shown that the medial temporal lobes (MTL) are more strongly engaged when individuals think about the future than about the present, leading to the suggestion that future projection drives MTL engagement. However, future thinking tasks often involve scene processing, leaving open the alternative possibility that scene-construction demands, rather than future projection, are responsible for the MTL differences observed in prior work. This study explores this alternative account. Using functional magnetic resonance imaging, we directly contrasted MTL activity in 1) high scene-construction and low scene-construction imagination conditions matched in future thinking demands and 2) future-oriented and present-oriented imagination conditions matched in scene-construction demands. Consistent with the alternative account, the MTL was more active for the high versus low scene-construction condition. By contrast, MTL differences were not observed when comparing the future versus present conditions. Moreover, the magnitude of MTL activation was associated with the extent to which participants imagined a scene but was not associated with the extent to which participants thought about the future. These findings help disambiguate which component processes of imagination specifically involve the MTL. Published by Oxford University Press 2016.

  7. Audit of electrical system construction projects at the Nevada Operations Office

    SciTech Connect

    1996-11-06

    The Nevada Test Site became the nation`s continental nuclear weapons test site on January 11, 1951. Over the years, the Nevada Operations Office (Nevada) built an extensive infrastructure to support and conduct nuclear tests at the site and in Las Vegas. Roads, housing, test towers, electrical systems, and water systems are just a few of the construction projects that have been required by the Site`s nuclear testing mission. Nuclear testing continued through 1992. A presidential decision directive issued in October that year stopped testing but required Nevada to conduct and experimental program and maintain a readiness posture to resume nuclear testing within 6 months through fiscal year 1995. The directive further required that, beginning with fiscal year 1996, Nevada maintain a 2-3 year readiness posture. This change in Nevada`s mission coupled with Department downsizing requires that only cost effective projects with defined mission needs be undertaken. Although Nevada has changed and rescoped some construction projects in response to the changing Test Site mission, there are two projects, one underway and one planned, that contain unneeded overlap of capability. Specifically, the audit identified two electrical system projects that provided unnecessary duplicate capability at a cost of about $1.35 million. Management concurred with our finding and agreed to implement the recommendation. Details of management`s comments and our response are included.

    The success of any construction project will depend on efficient management of resources in a perfect manner to complete the project with a reasonable budget and time and the quality cannot be compromised. The efficient and timely procurement of material, deployment of adequate labor at correct time and mobilization of machinery lacking in time, all of them causes delay, lack of quality and finally affect the project cost. It is known factor that Project cost can be controlled by taking corrective actions on mobilization of resources at a right time. This research focuses on integration of management systems with the computer to generate the model which uses OOM data structure which decides to include automatic commodity code generation, automatic takeoff execution, intelligent purchase order generation, and components of design and schedule integration to overcome the problems of stock out. To overcome the problem in equipment management system inventory management module is suggested and the data set of equipment registration number, equipment number, description, date of purchase, manufacturer, equipment price, market value, life of equipment, production data of the equipment which includes equipment number, date, name of the job, hourly rate, insurance, depreciation cost of the equipment, taxes, storage cost, interest, oil, grease, and fuel consumption, etc. is analyzed and the decision support systems to overcome the problem arising out improper management is generated. The problem on labor is managed using scheduling, Strategic management of human resources. From the generated support systems tool, the resources are mobilized at a right time and help the project manager to finish project in time and thereby save the abnormal project cost and also provides the percentage that can be improved and also research focuses on determining the percentage of delays that are caused by lack of management of materials, manpower and machinery in different types of projects

    The purpose of using unmanned aerial vehicle (UAV) remote sensing application in Five-hundred-meter aperture spherical telescope (FAST) project is to dynamically record the construction process with high resolution image, monitor the environmental impact, and provide services for local environmental protection and the reserve immigrants. This paper introduces the use of UAV remote sensing system and the course design and implementation for the FAST site. Through the analysis of the time series data, we found that: (1) since the year 2012, the project has been widely carried out; (2) till 2013, the internal project begun to take shape;(3) engineering excavation scope was kept stable in 2014, and the initial scale of the FAST engineering construction has emerged as in the meantime, the vegetation recovery went well on the bare soil area; (4) in 2015, none environmental problems caused by engineering construction and other engineering geological disaster were found in the work area through the image interpretation of UAV images. This paper also suggested that the UAV technology need some improvements to fulfill the requirements of surveying and mapping specification., including a new data acquisition and processing measures assigned with the background of highly diverse elevation, usage of telephoto camera, hierarchical photography with different flying height, and adjustment with terrain using the joint empty three settlement method.

  17. Bayesian-network-based safety risk assessment for steel construction projects.

    PubMed

    Leu, Sou-Sen; Chang, Ching-Miao

    2013-05-01

    There are four primary accident types at steel building construction (SC) projects: falls (tumbles), object falls, object collapse, and electrocution. Several systematic safety risk assessment approaches, such as fault tree analysis (FTA) and failure mode and effect criticality analysis (FMECA), have been used to evaluate safety risks at SC projects. However, these traditional methods ineffectively address dependencies among safety factors at various levels that fail to provide early warnings to prevent occupational accidents. To overcome the limitations of traditional approaches, this study addresses the development of a safety risk-assessment model for SC projects by establishing the Bayesian networks (BN) based on fault tree (FT) transformation. The BN-based safety risk-assessment model was validated against the safety inspection records of six SC building projects and nine projects in which site accidents occurred. The ranks of posterior probabilities from the BN model were highly consistent with the accidents that occurred at each project site. The model accurately provides site safety-management abilities by calculating the probabilities of safety risks and further analyzing the causes of accidents based on their relationships in BNs. In practice, based on the analysis of accident risks and significant safety factors, proper preventive safety management strategies can be established to reduce the occurrence of accidents on SC sites.

    The Iliamna-Newhalen-Nondalton Electric Cooperative (INNEC) provides electrical power to three communities of the same names. These communities are located near the north shore of Iliamna Lake in south-central Alaska approximately 175 miles southwest of Anchorage. These communities have a combined population of approximately 600 residents. There is no direct road connection from these villages to larger population centers. Electric power has been generated by INNEC since 1983 using diesel generators located in the community of Newhalen. Fuel for these generators was transported up the Kvichak River, an important salmon river, and across Iliamna Lake. In dry years the river is low and fuel is flown into Iliamna and then trucked five miles into Newhalen. The cost, difficult logistics and potential spill hazard of this fuel was a primary reason for development of hydroelectric power in this area. A hydroelectric project was constructed for these communities, starting in the spring of 1996 and ending in the spring of 1998. The project site is at Tazimina Falls about 9 miles upstream of the confluence of the Tazimina River and the Newhalen River. The project has an installed capacity of 824 kilowatts (kW) and is expandable to 1.5 megawatts (MW).

    Objective: The study focused on assessment of the health status of workers during construction phase of highway rehabilitation projects at six selected sites of N5 around Lahore, including Kala Shah Kaku, Muridke, Kamuki, Bhaipheru, Pattoki, and Okara. Methods: The study was based on multi-methods approach involving hazard identification through survey and checklist as well as a questionnaire for health status assessment and measurements of health parameters including peak expiratory flow rate (PEFR) and audiometric screening of 300 subjects. Results: The study revealed non-congenial working conditions at the sites. Noise, vibrations, dust, asphalt fumes, poor work postures, and injuries were found to be major health hazards. PEFR of most of the workers was found to be significantly lower than the reference value. Average PEFR±SEM values were 187±5.1 l/min, 178±4.3 l/min, and 266±5.3 l/min in ground preparation workers, asphalt workers, and heavy vehicle drivers, respectively. The highest rate (29%) of hearing loss was recorded among heavy vehicle drivers. Musculoskeletal problems were found to be more common among ground preparation workers. Conclusion: Data revealed unsatisfactory health status of most of the workers. Direct relationship between health outcomes and the type of construction activities were observed. The current study focuses on the importance of including occupational health and safety plan in the execution phase of every developmental project that involves construction activities.

    Cosmic ray tomography is a technique which exploits the multiple Coulomb scattering of highly penetrating cosmic ray-produced muons to perform non-destructive inspection of high-Z materials without the use of artificial radiation. A muon tomography detection system can be used as a portal monitor at border crossing points for detecting illegal targeted objects. The Muon Portal Project is a joint initiative between Italian research and industrial partners, aimed at the construction of a real size detector prototype (6×3×7 m3) for the inspection of cargo containers by the muon scattering technique. The detector consists of four XY tracking planes, two placed above and two below the container to be inspected. After a research and development phase, which led to the choice and test of the individual components, the construction and installation of the detection modules is almost completed. In this paper the present status of the Project is reported, focusing on the design and construction phase, as well as on the preliminary results obtained with the first detection planes.

    The Muon Portal Project is a joint initiative between research and industrial partners, aimed at the construction of a real size detector prototype (6 x 3 x 7 m{sup 3}) for the inspection of containers by the muon scattering technique, devised to search for hidden high-Z fissile materials and provide a full 3D tomography of the interior of the container in a scanning time of the order of minutes. The muon tracking detector is based on a set of 48 detection modules (size 1 m x 3 m), each built with 100 extruded scintillator strips, so as to provide four X-Y detection planes, two placed above and two below the container to be inspected. Two wavelength shifting (WLS) fibres embedded in each strip convey the emitted photons to Silicon Photomultipliers (SiPM) which act as photo-sensors. After a research and development phase, which led to the choice and test of the individual components, the construction of the full size detector has already started. The paper describes the results of the mass characterization of the photo-sensors and the construction and test measurements of the first detection modules of the Project. (authors)

  4. Estimating NOA Health Risks from Selected Construction Activities at the Calaveras Dam Replacement Project (CDRP)

    2012-12-01

    The CDRP is a major construction project involving up to 400 workers using heavy earth moving equipment, blasting, drilling, rock crushing, and other techniques designed to move 7 million yards of earth. Much of this material is composed of serpentinite, blueschist, and other rocks that contain chrysotile, crocidolite, actinolite, tremolite, and Libby-class amphiboles. To date, over 1,000 personal, work area, and emission inventory related samples have been collected and analyzed by NIOSH 7400, NIOSH 7402, and CARB-AHERA methodology. Data indicate that various CDRP construction activities have the potential to generate significant mineral fibers and structures that could represent elevated on site and off site health risks. This presentation will review the Contractors air monitoring program for this major project, followed by a discussion of predictive methods to evaluate potential onsite and offsite risks. Ultimately, the data are used for planning control strategies designed to achieve a Project Action Level of 0.01 f/cc (one tenth the Cal/OSHA PEL) and risk-based offsite target levels.

    2013-06-01

    Several factors should be considered by the owner and general contractor in the process of contractors` and subcontractors` selection and evaluation. The paper reviews the recent models addressed to guide general contractors in subcontractors' selection process and in evaluation of different contractors during the execution of the project. Moreover the paper suggests the impact of different contractors' performance to the overall level of occupational health and safety culture at the sites. It deals with the factors influencing the safety performance of contractors during construction and analyses the methods for assessing the safety performance of construction contractors. The results of contractors' safety performance evaluation could be a useful tool in motivating contractors to achieve better safety outcomes or could have effect on owners` or general contractors' decision making about contractors suitability for future contracting works.

  8. Improved Construction and Project Management for Future Nuclear Power Plants - Westinghouse Perspective

    SciTech Connect

    Matzie, Regis A.

    2002-07-01

    The economic competitiveness of future nuclear power plants is the key issue to the expansion of this vital technology. The challenge is greater today than it has been because of the worldwide trend of deregulation of the power market. Deregulation favors smaller investments with shorter payback times. However, the key economic parameter is the power generation cost and its competitiveness to other sources of electric generation, principally natural gas and coal. The relative competitiveness of these three fuel types today is largely dictated by the availability of domestic sources of both fuel and technology infrastructure. The competitiveness of new nuclear power plants can be improved in any power market environment first by the features of the design itself, second by the approach to construction, and finally by the project structure used to implement the plant, or more importantly, a series of plants. These three aspects form the cornerstone to a successful resurgence of new nuclear power plant construction. (author)

    Since 1996, the Government of the Hong Kong Special Administrative Region (HKSAR) has introduced the Pay for Safety Scheme (PFSS) to the public works construction contracts to uplift their safety performance. However, the adoption of PFSS has also encountered some difficulties that merit considerable attention. This paper purports to provide a concise review of the prevailing application of PFSS in Hong Kong in general, and to explore the potential difficulties associated with PFSS in particular. By means of an empirical questionnaire survey geared towards industrial practitioners with extensive direct hands-on PFSS experience, their opinions were solicited, analyzed and compared between the client group and contractor group of respondents. The three most significant difficulties in implementing PFSS were found to be: (1) "Plenty of paperwork required for certifying payment to contractor"; (2) "Complicated contract documents and lengthy assessment process"; and (3) "Over-tight project schedule requiring rush jobs". The output of this research study is particularly essential in assisting the contracting parties to mitigate the avoidable hindrances when embarking on PFSS. It has also generated valuable insights into developing effective recommendations for alleviating the barriers to PFSS success for future construction projects.

    Over the last three decades Brazil has developed a new community-based mental health policy. In this context it is important to reflect on the offers of care for users, and especially on how therapeutic projects are developed by professionals. This study was conducted with professionals working in community-based mental health services to investigate and understand their views on the construction of therapeutic projects and compare them with the concepts and theoretical proposals in Brazil's Mental Health Policy Guidelines and a review of the literature. Thirteen professionals who worked in mental health services located in three cities of the state of São Paulo, Brazil. Semi-structured interviews were conducted between September and November of 2009 to understand the views and mechanisms adopted by professionals in developing therapeutic projects. A bibliographical review laid the foundations for the theoretical research and for strengthening the basis of the data analysis. The professionals views are similar to those proposed in the relevant literature and Brazil's Mental Health Policy Guidelines. However, there is a need to invest in building new models to meet the needs of the population that requires mental health services. Clearer guidelines should be established to organize services and to provide adequate, sufficient training. The study suggests that attention and resources should be directed to strengthening training of professionals, and especially to qualifying the organization and administration of services in order to consolidate the new model.

  13. The effect of Problem/Project-Based Learning on a desired skill set for construction professionals

    NASA Astrophysics Data System (ADS)

    Sirotiak, Todd L.

    The purpose of this study was to investigate if a Problem/Project-Based Learning (PBL) approach can affect certain non-technical, "soft" skills of construction engineers. Such skills include leadership, adaptability, and stress management. In mixed design research, quantitative and qualitative data are assembled and analyzed collectively. For this study, two separate assessment tools were used for the quantitative portion, while open-ended written reflections and a partially closed-ended senior questionnaire were implemented for the qualitative portion. A hypothetical model was used to investigate certain soft skills based on prior research documenting need. Skills investigated were confidence, stress coping, leadership, communication skills, adaptability, and management skills. Descriptive statistics, open-ended final written reflections, and a partially closed-ended senior questionnaire were used to analyze the data. PBL is a process in which the students are challenged to develop realistic solutions on open, less structured, real world type problems. The results of this study performed with the combined count of nearly 60 students suggest that PBL can influence several soft skills of senior construction engineers. Specifically, these findings demonstrate the following: (a) PBL appears to affect students' soft skills; (b) students appear to recognize the realism and "real world" applicability that PBL brings to their skill development; and (c) the data suggest that the experience is holistic and offers opportunities for balanced growth in several ways. Some key competencies such as communication and leadership indicated significant enhancements. Although this study was limited to one academic year of the university's construction engineering program, it provides interesting insight to changes within the time period investigated. This study should be replicated in other construction engineering environments to investigate a larger population sample. In addition

    Our paper aims to unify and extend several approaches for building stable projection-based reduced order models (ROMs) using the energy method and the concept of “energy-stability”. Attention is focused on linear time-invariant (LTI) systems. First, an approach for building energy stable Galerkin ROMs for linear hyperbolic or incompletely parabolic systems of partial differential equations (PDEs) using continuous projection is proposed. The key idea is to apply to the system a transformation induced by the Lyapunov function for the system, and to build the ROM in the transformed variables. The result of this procedure will be a ROM that is energy-stable for any choice of reduced basis. It is shown that, for many PDE systems, the desired transformation is induced by a special inner product, termed the “symmetry inner product”. Next, attention is turned to building energy-stable ROMs via discrete projection. A discrete counterpart of the continuous symmetry inner product, termed the “Lyapunov inner product”, is derived. Moreover, it is shown that the Lyapunov inner product can be computed in a black-box fashion for a stable LTI system ari sing from the discretization of a system of PDEs in space. Projection in this inner product guarantees a ROM that is energy-stable, again for any choice of reduced basis. Connections between the Lyapunov inner product and the inner product induced by the balanced truncation algorithm are made. We also made comparisons between the symmetry inner product and the Lyapunov inner product. Performance of ROMs constructed using these inner products is evaluated on several benchmark test cases.

    BIM is targeted at providing information about the entire building and a complete set of design documents and data stored in an integrated database. In this paper, we study the use of BIM in two life-cycle construction projects in Kuopio, Finland during 2011. The analysis of uses of BIM and their main problems will constitute a foundation for an intervention. We will focus on the following questions: (1) How different partners use the composite BIM model? (2) What are the major contradictions or problems in the BIM use? The preliminary findings reported in this study show that BIM has been adopted quite generally to design use but the old ways of collaboration seem to prevail, especially between designers and between designers and building sites. BIM has provided new means and demands for collaboration but expansive uses of BIM for providing new interactive processes across professional fields have not much come true.

    A four metre diameter 770 m long buried steel penstock was constructed for the 20 MW Raymond Reservoir Hydro Project in southern Alberta. The penstock delivers up to 56.7 m{sup 3}/sec of irrigation water at an effective head of 44 m to a 2.6 m diameter Kaplan turbine. The hydro facility was commissioned in the spring of 1994. The steel pipe was delivered to the site in 18 m long sections from a fabrication plant located 250 km away. Specialized equipment was engineered and constructed to externally coat and internally line the pipe sections on site. The pipe sections, weighing from 27,000 to 30,000 kg, were rolled and moved on a specially built lathe during the external sandblasting and tape wrapping operation. The external tape wrapping is one element of the cathodic protection system for the steel pipe. Specialized equipment was modified to sandblast the interior to white metal and then mechanically apply three coats of internal epoxy lining. The internal lining improves the hydraulic characteristics of the pipe in addition to protecting the pipe from corrosion. This innovative approach to coating and lining the pipe resulted in an exceptionally high quality product at an affordable cost.

It also summarizes U.S. Nuclear Regulatory Commission (NRC) surveillances. One radiological audit and three radiological surveillances were performed at the Falls City site. These surveillances and audit, which resulted in 31 observations, focused primarily on processing site activities and were performed on the following dates: 3-6 August 1992, 29-30 October 1992, 22-26 March 1993, and 1-3 November 1993. All outstanding radiological issues were closed out at the completion of the construction activities. Six QA in-process surveillances, which resulted in 71 observations, were performed at the Falls City site on the following dates: 22-24 July 1992, 23-25 November 1992, 17-19 May 1993, 16-18 August 1993, 13-15 October 1993, and 2-4 February 1994. All outstanding issues were closed out with the February surveillance on 3 March 1994. The DOE/TAC remedial action close-out inspections of the Falls City site, which resulted in 56 observations, were conducted 9-10 June 1994 and 26 July 1994. The inspections were closed out on 26 January 1995. The NRC performed three on-site construction reviews (OSCR), resulting in seven observations of remedial action construction activities that occurred during site visits. The OSCRs were performed 9 December 1992, 12 May 1993, and 25 October 1993. Since all audit and surveillance observations and recommendations have been closed out, this final audit report segment of the site certification process is complete.

    2011-06-01

    The new EU challenge is to recover 70% by weight of C&D waste in 2020. Literature reveals that one major barrier is the lack of data. Therefore, this paper presents a model which allows technicians to estimate C&D waste during the design stage in order to promote prevention and recovery. The types and quantities of CW are estimated and managed according to EU guidelines, by building elements and specifically for each project. The model would allow detection of the source of the waste and to adopt other alternative procedures which delete hazardous waste and reduce CW. Likewise, it develops a systematic structure of the construction process, a waste classification system and some analytical expressions which are based on factors. These factors depend on technology and represent a standard on site. It would allow to develop a database of waste anywhere. A Spanish case study is covered. Factors were obtained by studying over 20 dwellings. The source and types of packaging waste, remains, soil and hazardous waste were estimated in detail and were compared with other studies. Results reveal that the model can be implemented in projects and the chances of reducing and recovery C&D waste could be increased, well above the EU challenge. Copyright © 2011 Elsevier Ltd.

    Multilayer fractional quantum Hall wave functions can be used to construct the non-Abelian states of the Zk Read-Rezayi series upon symmetrization over the layer index. Unfortunately, this construction does not yield the complete set of Zk ground states on the torus. We develop an alternative projective construction of Zk Read-Rezayi states that complements the existing one. On the multilayer torus geometry, our construction consists of introducing twisted boundary conditions connecting the layers before performing the symmetrization. We give a comprehensive account of this construction for bosonic states, and numerically show that the full ground state and quasihole manifolds are recovered for all computationally accessible system sizes. Furthermore, we analyze the neutral excitation modes above the Moore-Read on the torus through an extensive exact diagonalization study. We show numerically that our construction can be used to obtain excellent approximations to these modes. Finally, we extend our symmetrization scheme to the plane and sphere geometries.

    The Riegel Textile Corporation completed a 2163 kW generator project at its plant in Fries, Virginia. A new powerhouse was constructed to enclose a used 2900 hp vertical Kaplan turbine and Westinghouse generator. Construction was accomplished without modification to or rehabilitation of an existing dam and required only minor modification to or rehabilitation of an existing dam and required only minor modification to the existing appurtenances. The existing hydro-generation equipment supplies approximately 54% of the 5500 kW required by the Fries plant. With the addition of the new facility, the plant will generate approximately 74% of its total electrical requirements. This demonstrates the viability of utilizing hydro-generation in the operation of an industrial facility. The project annually generates a National Energy Savings of 19,387 barrels of oil equivalent. The project was separated into four phases which lasted a total of 36 months and included construction, erection and demonstration.

    Time in infrastructure construction projects has always been a fundamental issue as early as from the inception of a project, during the construction process and often after the completion and delivery. In a typical construction contract time related matters such as the completion date and possible delays are among the most important issues that are dealt with by the contract provisions. In the event of delay there are usually provisions for extension of time award to the contractor with possible reimbursement for the extra cost and expenses caused by this extension of time to the contract duration. In the case the contractor is not entitled to extension of time, the owner will be possibly entitled to amounts as compensation for the time prohibited from using his development. Even in the event of completion within the time agreed, under certain circumstances a contractor may have claims for reimbursement for extra costs incurred due to induced acceleration measures he had to take in order to mitigate disruption effects caused to the progress of the works by the owner or his representatives. Depending on the size of the project and the agreement amount, these reimbursement sums may be extremely high. Therefore innovative methods with the exploitation of new technologies for effective project management for the avoidance of delays, delay analysis and mitigation measures are essential; moreover, methods for collecting efficiently information during the construction process so that disputes regarding time are avoided or resolved in a quick and fair manner are required. This paper explores the state of art for existing use of Building Information Modelling (BIM) and Unmanned Aerial Vehicles (UAV) technologies in the construction industry in general. Moreover the paper considers the prospect of using BIM technology in conjunction with the use of UAV technology for efficient and accurate as-built data collection and illustration of the works progress during an

  17. Office of Inspector General report on audit of renovation and new construction projects at Lawrence Livermore National Laboratory

    SciTech Connect

    1997-06-05

    The Oakland Operations Office (Oakland) is responsible for acquiring facilities needed to satisfy mission needs and to do so at the least cost to the Department of Energy (Department). The objective of the audit was to determine if proposed renovation and new construction projects at the Lawrence Livermore National Laboratory (Livermore) met mission needs while minimizing cost to the Government. In pursuing three projects, estimated to cost over $78 million, Livermore had not demonstrated that it had selected the best alternatives for meeting the Department`s needs while minimizing cost. Livermore was able to pursue these projects because Oakland did not ensure that the laboratory had performed cost and benefit analyses of all alternatives. Further, Oakland did not establish benchmarks to assess the reasonableness of the total costs of designing, constructing, and managing these projects. As a result, it was likely that the Department was spending more than necessary on renovation and new construction projects at Livermore. Although the projects met mission needs, it was recommended that the Manager, Oakland: (1) require Livermore to perform analyses of expected costs and benefits for alternatives; (2) evaluate the adequacy of Livermore`s cost and benefit analyses of alternatives; (3) establish benchmarks based on industry and other government agency cost data to assess the reasonableness of Livermore`s total design, construction, and project management costs; and (4) select the alternative that meets established needs at the least cost to the Government. Oakland agreed with the recommendations and will implement them starting with the Fiscal Year 1999 project submission and validation.

  18. Multimode Resource-Constrained Multiple Project Scheduling Problem under Fuzzy Random Environment and Its Application to a Large Scale Hydropower Construction Project

    2014-01-01

    This paper presents an extension of the multimode resource-constrained project scheduling problem for a large scale construction project where multiple parallel projects and a fuzzy random environment are considered. By taking into account the most typical goals in project management, a cost/weighted makespan/quality trade-off optimization model is constructed. To deal with the uncertainties, a hybrid crisp approach is used to transform the fuzzy random parameters into fuzzy variables that are subsequently defuzzified using an expected value operator with an optimistic-pessimistic index. Then a combinatorial-priority-based hybrid particle swarm optimization algorithm is developed to solve the proposed model, where the combinatorial particle swarm optimization and priority-based particle swarm optimization are designed to assign modes to activities and to schedule activities, respectively. Finally, the results and analysis of a practical example at a large scale hydropower construction project are presented to demonstrate the practicality and efficiency of the proposed model and optimization method.

  20. The tail wags the dog: managing large telescope construction projects with lagging requirements and creeping scope

    In a perfect world, large telescopes would be developed and built in logical, sequential order. First, scientific requirements would be agreed upon, vetted, and fully developed. From these, instrument designers would define their own subsystem requirements and specifications, and then flesh out preliminary designs. This in turn would then allow optic designers to specify lens and mirror requirements, which would permit telescope mounts and drives to be designed. Finally, software and safety systems, enclosures and domes, buildings, foundations, and infrastructures would be specified and developed. Unfortunately, the order of most large telescope projects is the opposite of this sequence. We don't live in a perfect world. Scientists usually don't want to commit to operational requirements until late in the design process, instrument designers frequently change and update their designs due to improving filter and camera technologies, and mount and optics engineers seem to live by the words "more" and "better" throughout their own design processes. Amplifying this is the fact that site construction of buildings and domes are usually the earliest critical path items on the schedule, and are often subject to lengthy permitting and environmental processes. These facility and support items therefore must quickly get underway, often before operational requirements are fully considered. Mirrors and mounts also have very long lead times for fabrication, which in turn necessitates that they are specified and purchased early. All of these factors can result in expensive and time-consuming change orders when requirements are finalized and/or shift late in the process. This paper discusses some of these issues encountered on large, multi-year construction projects. It also presents some techniques and ideas to minimize these effects on schedule and cost. Included is a discussion on the role of Interface Control Documents (ICDs), the importance (and danger) of making big

  1. Constructing optimal ensemble projections for predictive environmental modelling in Northern Eurasia

    Large uncertainties in climate impact modelling are associated with the forcing climate data. This study is targeted at the evaluation of the quality of GCM-based climatic projections in the specific context of predictive environmental modelling in Northern Eurasia. To accomplish this task, we used the output from 36 CMIP5 GCMs from the IPCC AR-5 data base for the control period 1975-2005 and calculated several climatic characteristics and indexes that are most often used in the impact models, i.e. the summer warmth index, duration of the vegetation growth period, precipitation sums, dryness index, thawing degree-day sums, and the annual temperature amplitude. We used data from 744 weather stations in Russia and neighbouring countries to analyze the spatial patterns of modern climatic change and to delineate 17 large regions with coherent temperature changes in the past few decades. GSM results and observational data were averaged over the coherent regions and compared with each other. Ultimately, we evaluated the skills of individual models, ranked them in the context of regional impact modelling and identified top-end GCMs that "better than average" reproduce modern regional changes of the selected meteorological parameters and climatic indexes. Selected top-end GCMs were used to compose several ensembles, each combining results from the different number of models. Ensembles were ranked using the same algorithm and outliers eliminated. We then used data from top-end ensembles for the 2000-2100 period to construct the climatic projections that are likely to be "better than average" in predicting climatic parameters that govern the state of environment in Northern Eurasia. The ultimate conclusions of our study are the following. • High-end GCMs that demonstrate excellent skills in conventional atmospheric model intercomparison experiments are not necessarily the best in replicating climatic characteristics that govern the state of environment in Northern Eurasia

    This document serves as a Notice of Construction for the Phase 2 activities of Project W-320, 241-C-106 Tank Sluicing, pursuant to the requirements of Washington Administrative Codes (WAC) 173-400 and 173-460. Phased permitting for Project W-320 was discussed with the Washington State Department of Ecology (Ecology) on November 2, 1993. In April 1994, it was deemed unnecessary because the Phase 1 activities did not constitute a new source of emissions and therefore did not require approval from Ecology. The 241-C-106 tank is a 2-million liter capacity, single-shell tank (SST) used for radioactive waste storage since 1947. Between mid-1963 and mid-1969, 241-C-106 tank received high-heat waste, PUREX (plutonium-uranium extraction) Facility high-level waste, and strontium-bearing solids from the strontium and cesium recovery activities. In 1971, temperatures exceeding 99 C were observed in the tank, and therefore, a ventilation system was installed to cool the tank. In addition, approximately 22,712 liters of cooling water are added to the tank each month to prevent the sludge from drying out and overheating. Excessive drying of the sludge could result in possible structural damage. The current radiolytic heat generation rate has been calculated at 32 kilowatts (kW) plus or minus 6 kW. The 241-C-106 tank was withdrawn from service in 1979 and currently is categorized as not leaking. The heat generation in 241-C-106 tank has been identified as a key safety issue on the Hanford Site. The evaporative cooling provided by the added water during operation and/or sluicing maintains the 241-C-106 tank within its specified operating temperature limits. Project W-320, 241-C-106 Tank Sluicing, will mobilize and remove the heat-generating sludge, allowing the water additions to cease. Following sludge removal, the 241-C-106 tank could be placed in a safe, interim stabilized condition. Tank-to-tank sluicing, an existing, proven technology, will provide the earliest possible

    Hudson, R. Dennis

    2008-01-01

    On December 5, 1980, Congress passed the Pacific Northwest Electric Power Planning and Conservation Act (Public Law 96-501). The Act created the Northwest Power Planning Council (now the Northwest Power and Conservation Council). The Council was charged with the responsibility to prepare a Regional Conservation and Electric Power Plan and to develop a program to protect, mitigate, and enhance fish and wildlife including related spawning grounds and habitat on the Columbia River and its tributaries. The Council adopted its Fish and Wildlife Program on November 15, 1982. Section 800 of the Program addresses measures in the Yakima River Basin. The Yakima measures were intended to help mitigate hydroelectric impacts in the basin and provide off-site mitigation to compensate for fish losses caused by hydroelectric project development and operations throughout the Columbia River Basin. The Bonneville Power Administration (BPA) was designated as a major source of funding for such off-site mitigation measures and was requested to initiate discussions with the appropriate Federal project operators and the Council to determine the most expeditious means for funding and implementing the program. The primary measures proposed for rapid implementation in the Yakima River basin were the installation of fish passage and protective facilities. Sec. 109 of The Hoover Power Plant Act of 1984, authorized the Secretary of the Interior to design, construct, operate, and maintain fish passage facilities within the Yakima River Basin. Under Phase I of the program, improvements to existing fish passage facilities and installation of new fish ladders and fish screens at 16 of the largest existing diversion dams and canals were begun in 1984 and were completed in 1990. The Yakima Phase II fish passage program is an extension of the Phase I program. In 1988, the Yakama Nation (YN) submitted an application to amend Sections 803(b) and 1403(4.5) of the Northwest Power and Conservation Council

    The primary aim of the INTERGROWTH-21st Project is to construct new, prescriptive standards describing optimal fetal and preterm postnatal growth. The anthropometric measurements include the head circumference, recumbent length and weight of the infants, and the stature and weight of the parents. In such a large, international, multicentre project, it is critical that all study sites follow standardised protocols to ensure maximal validity of the growth and nutrition indicators used. This paper describes, in detail, the selection of anthropometric personnel, equipment, and measurement and calibration protocols used to construct the new standards. Implementing these protocols at each study site ensures that the anthropometric data are of the highest quality to construct the international standards. PMID:23841804

    The HIGHWET project combines the hydrolytic up-flow sludge bed (HUSB) anaerobic digester and constructed wetlands (CWs) with forced aeration for decreasing the footprint and improving effluent quality. The HIGHWET plant in A Coruña (NW of Spain) treating municipal wastewater consists of a HUSB and four parallel subsurface horizontal flow (HF) CWs. HF1, HF2 and HF3 units are fitted with forced aeration, while the control HF4 is not aerated. All the HF units are provided with effluent recirculation, but different heights of gravel bed (0.8 m in HF1 and HF2, and 0.5 m in HF3 and HF4) are implemented. Besides, a tobermorite-enriched material was added in the HF2 unit in order to improve phosphorus removal. The HUSB 76-89% of total suspended solids (TSS) and about 40% of chemical oxygen demand (COD) and biological oxygen demand (BOD). Aerated HF units reached above 96% of TSS, COD and BOD at a surface loading rate of 29-47 g BOD5/m(2)·d. An aeration regime ranging from 5 h on/3 h off to 3 h on/5 h off was found to be adequate to optimize nitrogen removal, which ranged from 53% to 81%. Average removal rates of 3.4 ± 0.4 g total nitrogen (TN)/m(2)·d and 12.8 ± 3.7 g TN/m(3)·d were found in the aerated units, being 5.5 and 4.1 times higher than those of the non-aerated system. The tobermorite-enriched HF2 unit showed a distinct higher phosphate (60-67%) and total phosphorus (54%) removal.

  6. Robotic Lunar Drilling Development for the Construction and Resource Utilization Explorer (CRUX) Project.

    Zacny, K.; Bartlett, P. W.; Glaser, D.

    2005-12-01

    The Construction Resource Utilization eXplorer (CRUX) Project is a NASA funded R&D project intended to provide technology for the exploration of lunar and planetary surfaces and subsurfaces. CRUX will have ten instruments, six of which will require subsurface access. Central to the CRUX project is a low power, low mass, robotic drilling system capable of reaching, and delivering scientific instruments to, a target depth currently set at 2 m. Two drilling methods for lunar application have been investigated thus far. The first uses purely rotary drilling, and the second rotary-percussive drilling, similar to what was used by the Apollo astronauts. Both drilling methods utilize an auger for the removal of drilled cuttings. A breadboard drilling system able to function in rotary-drag and rotary-percussive modes was produced to develop and prove out the approach through testing. Spacecraft weight, power, soil properties, and environments are among the key design constraints. The drilling algorithm, rotation and penetration rates, drill bit designs, and auger designs are among the key design variables. The test results presented demonstrate the progress made in simulating the environment, designing an automated system to perform in it, and characterizing the performance of the system. During the initial phase of the research effort, drilling tests were performed in two different lunar soil simulants (FJS-1 and JSC-1, made in Japan and the USA respectively) that were prepared in the following manner. Each soil sample was first mixed with 10wt% distilled water, compacted to 2 g/cc using the Modified Proctor Test (ASTM D1557), and then frozen at 190K. Under these conditions, the soil became as hard as sandstone and served to simulate the water-rich soils that are theorized to exist in permanently shaded craters at the lunar poles. The high bulk density, high water concentration, and binding nature of the water within the regolith were all chosen to serve as a worst case to

    This project-based learning combined the chemistry of separation process using steam distillation with engineering design process in an undergraduate chemistry course. Students built upon their knowledge of phase changes, immiscible mixture, and the relationship between vapor pressure and boiling point to complete a project of modifications steam distillation apparatus. The research method is a qualitative case study, which aims to describe how (1) the creative thinking skills of students emerged during six weeks of theproject, (2) students built steam distillation apparatus characteristics as the project product and (3) students response to the project-based learning model. The results showed that the students had successfully constructed a steam distillation apparatus using plastic kettle as steam generator and distillation flask. A Plastic tubewas used to drain water vapor from steam generator to distillation flask and to drain steam containing essential oil to the condenser. A biscuit tin filled with ice was used as a condenser. The time required until resulting distillate was fifteen minutes. The production of essential was conductive qualitatively by a very strong smell typical of essential oil and two phases of distillate. Throughout the project, students formulated the relevant and varied problem, formulated the goals, proposed the ideas of the apparatus and materials, draw apparatus design, constructed apparatus, tested apparatus, evaluated, and reported the project. Student response was generally positive. They were pleased, interested, more understanding the concepts and work apparatus principles, also implemented new ideas. These results indicate that project-based learning can develop students' creative thinking skills. Based on these results, it is necessary to conduct research and implemented project-based learning to other concepts.

  1. Student use of a Learning Management System for group projects: A case study investigating interaction, collaboration, and knowledge construction

    NASA Astrophysics Data System (ADS)

    Lonn, Steven D.

    Web-based Learning Management Systems (LMS) allow instructors and students to share instructional materials, make class announcements, submit and return course assignments, and communicate with each other online. Previous LMS-related research has focused on how these systems deliver and manage instructional content with little concern for how students' constructivist learning can be encouraged and facilitated. This study investigated how students use LMS to interact, collaborate, and construct knowledge within the context of a group project but without mediation by the instructor. The setting for this case study was students' use in one upper-level biology course of the local LMS within the context of a course-related group project, a mock National Institutes of Health grant proposal. Twenty-one groups (82 students) voluntarily elected to use the LMS, representing two-thirds of all students in the course. Students' peer-to-peer messages within the LMS, event logs, online surveys, focus group interviews, and instructor interviews were used in order to answer the study's overarching research question. The results indicate that students successfully used the LMS to interact and, to a significant extent, collaborate, but there was very little evidence of knowledge construction using the LMS technology. It is possible that the ease and availability of face-to-face meetings as well as problems and limitations with the technology were factors that influenced whether students' online basic interaction could be further distinguished as collaboration or knowledge construction. Despite these limitations, students found several tools and functions of the LMS useful for their online peer interaction and completion of their course project. Additionally, LMS designers and implementers are urged to consider previous literature on computer-supported collaborative learning environments in order to better facilitate independent group projects within these systems. Further research is

  2. Constructing failure in big biology: The socio-technical anatomy of Japan's Protein 3000 Project.

    PubMed

    Fukushima, Masato

    2016-02-01

    This study focuses on the 5-year Protein 3000 Project launched in 2002, the largest biological project in Japan. The project aimed to overcome Japan's alleged failure to contribute fully to the Human Genome Project, by determining 3000 protein structures, 30 percent of the global target. Despite its achievement of this goal, the project was fiercely criticized in various sectors of society and was often branded an awkward failure. This article tries to solve the mystery of why such failure discourse was prevalent. Three explanatory factors are offered: first, because some goals were excluded during project development, there was a dynamic of failed expectations; second, structural genomics, while promoting collaboration with the international community, became an 'anti-boundary object', only the absence of which bound heterogeneous domestic actors; third, there developed an urgent sense of international competition in order to obtain patents on such structural information.

  5. Investigating the multi-causal and complex nature of the accident causal influence of construction project features.

    Manu, Patrick A; Ankrah, Nii A; Proverbs, David G; Suresh, Subashini

    2012-09-01

    Construction project features (CPFs) are organisational, physical and operational attributes that characterise construction projects. Although previous studies have examined the accident causal influence of CPFs, the multi-causal attribute of this causal phenomenon still remain elusive and thus requires further investigation. Aiming to shed light on this facet of the accident causal phenomenon of CPFs, this study examines relevant literature and crystallises the attained insight of the multi-causal attribute by a graphical model which is subsequently operationalised by a derived mathematical risk expression that offers a systematic approach for evaluating the potential of CPFs to cause harm and consequently their health and safety (H&S) risk implications. The graphical model and the risk expression put forth by the study thus advance current understanding of the accident causal phenomenon of CPFs and they present an opportunity for project participants to manage the H&S risk associated with CPFs from the early stages of project procurement.

  10. Projection of climate change Impact on water resources for hydropower and irrigation under new dam construction in the Mekong River

    NASA Astrophysics Data System (ADS)

    Kudo, R.; Masumoto, T.; Horikawa, N.; Yoshida, T.

    2011-12-01

    1. Introduction Many projects for water resources development are planned in the Mekong River basin. Hydrological cycles in river basins are affected by such developments as well as by climate change. In Laos there are about 70 hydroelectric power projects and several hydroelectric dams are currently under construction upstream from the Nam Ngum dam (NN1 dam), one of the largest hydroelectric dams in the Mekong River. In this study, the combined impacts of climate change and the construction of new dams on water resources in the Nam Ngum River were investigated by using a distributed hydrological model, a reservoir operation model, and future climate scenarios based on a Global Climate Model (GCM). 2. Distributed Hydrological and Reservoir Operation Models The hydrological model used in this study contains four sub-models, evapotranspiration, cropping pattern and area, agricultural water use, and runoff. For modeling, a basin is divided into a 10 km grid and the ratios of five land-use categories (forest, rain-fed paddy, irrigated paddy, upland field, and water body) are set for each grid cell. A reservoir operation model was developed to represent the operation of dams in the Nam Ngum River basin and this model was incorporated in the distributed hydrological model. This model was applied to the NN1 dam and other new dams. 3. Data and Methods Future climate scenarios simulated by MRI-AGCM3.1S (SRES-A1B), a GCM developed by Meteorological Research Institute (MRI) of Japan, were used as input data for the hydrological model. The climate scenarios were statistically corrected to eliminate biases between the GCM simulations and the observations. Simulations were carried out for five scenarios: Present: Without dam construction under present climate conditions (1979-2003) Near future1: Without dam construction under near future climate conditions (2015-2039) Near future2: With dam construction under near future climate conditions (2015-2039) Future1: Without dam

  11. Evaluation of the varying Naturally Occurring Asbestos mitigation measures at School and Commercial construction projects in California

    NASA Astrophysics Data System (ADS)

    Kalika, S.

    2012-12-01

    In commercial development or K-12 school construction, project sites are often purchased and much of the planning process completed prior to an assessment of the soils proposed for excavation or potential offhaul. Geologic maps, while initially helpful for identifying potential hazards such as landslides and earthquake faults, are less helpful in the identification of naturally occurring hazardous minerals, such as the seven regulated minerals currently classified as asbestos. Geologic maps identify mafic and ultramafic bedrock zones; however, a skilled geologist with knowledge of asbestos hazards will further visualize the earth-shaping processes that may have resulted in the deposition of naturally occurring asbestos in locations outside mapped ultramafic zones including the base of an alluvial fan or within streambed channels. When sampled as an afterthought prior to disposal, property owners are surprised by the budget-crippling costs of waste handling and disposal of NOA, as well as mitigations required to protect the health of construction workers, the public, and future site occupants. The California Air Resources Board (CARB) continues to lead the way in evaluation and regulation of NOA, through development of the CARB 435 preparation and laboratory analytical method, local enforcement of the Asbestos Airborne Toxic Control Measure for Construction, Grading, Quarrying, and Surface Mining Operations (ATCM), and implementation of dust control measures to protect public health. A thorough site evaluation and construction design includes utilization of the sampling methods developed by the California Geological Survey, laboratory analytical methods within CARB 435, and mitigation measures required by CARB, DTSC, and OSHA for the protection of worker and public health after NOA is discovered. The site evaluation should additionally include an assessment of the future site usage, as regulations differ based on potential health affects to future occupants

    Inquiry is widely recognized as an effective method for science teaching. Exploration of the local environment lends itself well to this method. However, to foster understanding about the broader global scale of the Earth system, another approach is needed. Here we present two projects that seek to provide motivation and resources for helping K-12 students construct their own understanding of our Earth system. The S`COOL Project, begun in 1997, seeks to motivate students across the entire K-12 spectrum (with a particular focus on upper elementary grades) to learn relevant science basics and how these basics tie in to a larger picture. The project uses a connection to an on-going NASA science investigation, the Clouds and the Earth`s Radiant Energy System (CERES) project, as a powerful motivator. Student cloud observations coordinated with the passage of orbiting satellite instruments provide useful validation information for the CERES science team. The students receive timely feedback, with a simple and direct link to the corresponding piece of satellite data. Finally, students are encouraged to perform data analysis through an on-line database and the provision of simple tools that allow students to look at not only their own familiar observations, but also those from other participants around the world. The project is placed in the context of our efforts to understand the Earth's energy balance, which controls our climate. The MY NASA DATA project, begun in 2004, provides K-12 students (with a particular focus on middle and high school) with direct on-line access to Earth system science data for global inquiry. The project collects over 140 Earth system science parameters from NASA and other government resources through a single, relatively simple, web-based visualization interface. In addition to offering a large number of contributed lesson plans and science projects on specific topics, this website enables students to explore their own inquiry questions to

    1991-12-01

    The Yucca Mountain Site Characterization Project is studying Yucca Mountain in southwestern Nevada as a potential site for a high-level nuclear waste repository. Site characterization includes surface-based and underground testing. Analyses have been performed to design site characterization activities with minimal impact on the ability of the site to isolate waste, and on tests performed as part of the characterization process. One activity of site characterization is the construction of an Exploratory Studies Facility, for which many design options are being considered, including shafts, drifts, and ramps. The information in this report pertains to: (1) engineering calculations of the potential distribution of residual water from constructing the shafts and drifts; (2) numerical calculations predicting the movement of residual construction water from the shaft and drift walls into the rock; and (3) numerical calculations of the movement of residual water and how the movement is affected by ventilation. This document contains information that has been used in preparing Appendix 1 of the Exploratory Studies Facility Design Requirements document for the Yucca Mountain Project.

  9. An assessment of potential hydrologic and ecologic impacts of constructing mitigation wetlands, Rifle, Colorado, UMTRA project sites

    SciTech Connect

    1995-04-01

    This-assessment examines the consequences and risks that could result from the proposed construction of mitigation wetlands at the New and Old Rifle Uranium Mill Tailings Remedial Action (UMTRA) Project sites near Rifle, Colorado. Remediation of surface contamination at those sites is now under way. Preexisting wetlands at or near the Old and New Rifle sites have been cleaned up, resulting in the loss of 0.7 and 10.5 wetland acres (ac) (0.28 and 4.2 hectares [ha]) respectively. Another 9.9 ac (4.0 ha) of wetlands are in the area of windblown contamination west of the New Rifle site. The US Army Corps of Engineers (USACE) has jurisdiction over the remediated wetlands. Before remedial action began, and before any wetlands were eliminated, the USACE issued a Section 404 Permit that included a mitigation plan for the wetlands to be lost. The mitigation plan calls for 34.2 ac (1 3.8 ha) of wetlands to be constructed at the south end and to the west of the New Rifle site. The mitigation wetlands would be constructed over and in the contaminated alluvial aquifer at the New Rifle site. As a result of the hydrologic characteristics of this aquifer, contaminated ground water would be expected to enter the environment through the proposed wetlands. A preliminary assessment was therefore required to assess any potential ecological risks associated with constructing the mitigation wetlands at the proposed location.

    The lessons learned during the early phase of design engineering and construction activities for the AP1000 China Project can be applied to any project involving multiple disciplines and multiple organizations. Implementation of a first-of-a-kind design to directly support construction activities utilizing resources assigned to design development and design delivery creates challenges with prioritization of activities, successful closure of issues, and communication between site organizations and the home office. To ensure successful implementation, teams were assigned and developed to directly support construction activities including prioritization of activities, site communication and ensuring closure of site emergent issues. By developing these teams, the organization is better suited to meet the demands of the construction schedule while continuing with design evolution of a standard plant and engineering delivery for multiple projects. For a successful project, proper resource utilization and prioritization are key for overcoming obstacles and ensuring success of the engineering organization. (authors)

  19. Model based prognosis of contaminant leaching for reuse of demolition waste in construction projects

    In this study, groundwater contamination from recycled demolitian waste in road constructions is assessed using predictions of leachate concentrations. Numerical transport simulations are performed for three scenarios (a parking lot, a noise protection barrier, and road), and using a number of characteristic subsoils of Germany, to estimate the breakthrough of different contaminant classes at the groundwater table. Conservative tracer breakthrough times (BTT) primarily depend on subsoil hydraulic properties, for organic pollutants KOC and subsoil OC are the controlling parameters. Significant concentration reductions from dispersion only occur when source concentrations decrease prior to contaminant breakthrough. If source concentrations remain high for long periods relative to peak BTT, concentration breakthrough is undamped. Accounting for biodegradation reduces breakthrough concentrations significantly. For the “noise protection barrier” and “road” scenarios, capillary barrier effects cause the seepage water to partially bypass the recycling material. Accounting for this bypass flow and spatial averaging across the constructions reduces concentrations by about 30-40 %.

  20. Measured Infiltration and Ventilation in Manufactured Homes : Residential Construction Demonstration Project, Cycle II.

    Palmiter, Larry S.; Ecotope, Inc.

    1992-04-28

    Air infiltration is an important factor in heat loss and indoor air quality; in modern well-insulated homes, it may account for as much as half of the total heat loss. Due to the recent emphasis by home buyers and manufacturers on energy efficiency, tighter homes are being constructed. In the past, it was assumed that natural infiltration would provide adequate ventilation to maintain acceptable indoor air quality, but this is no longer the case in modern energy-efficient homes. This report summarizes the results of infiltration measurements made on two groups of manufactured homes in the Bonneville Power Administration (BPA) service area: 131 energy-efficient homes constructed under RCDP, and a control group of 29 homes not participating in energy-efficiency programs.

    Altaleb, Anas; Saeed, Muhammad Sarwar; Hussain, Iqtadar; Aslam, Muhammad

    2017-03-01

    The aim of this work is to synthesize 8*8 substitution boxes (S-boxes) for block ciphers. The confusion creating potential of an S-box depends on its construction technique. In the first step, we have applied the algebraic action of the projective general linear group PGL(2,GF(28)) on Galois field GF(28). In step 2 we have used the permutations of the symmetric group S256 to construct new kind of S-boxes. To explain the proposed extension scheme, we have given an example and constructed one new S-box. The strength of the extended S-box is computed, and an insight is given to calculate the confusion-creating potency. To analyze the security of the S-box some popular algebraic and statistical attacks are performed as well. The proposed S-box has been analyzed by bit independent criterion, linear approximation probability test, non-linearity test, strict avalanche criterion, differential approximation probability test, and majority logic criterion. A comparison of the proposed S-box with existing S-boxes shows that the analyses of the extended S-box are comparatively better.

  20. Project Independence: Construction of an Integrated Biorefinery for Production of Renewable Biofuels at an Existing Pulp and Paper Mill

    SciTech Connect

    Freeman, Douglas

    2012-06-01

    Project Independence proposed to construct a demonstration biomass-to-liquids (BTL) biorefinery in Wisconsin Rapids, isconsin. The biorefinery was to be co-located at the existing pulp and paper mill, NewPage Wisconsin System Incorporated’s Wisconsin Rapids Mill, and when in full operation would both generate renewable energy for Wisconsin Rapids Mill and produce liquid fuels from abundant and renewable lignocellulosic biomass. The biorefinery would serve to validate the thermochemical pathway and economic models for BTL production using forest residuals and wood waste, providing a basis for proliferating BTL conversion technologies throughout the United States. It was a project goal to create a compelling new business model for the pulp and paper industry, and support the nation’s goal for increasing renewable fuels production and reducing its dependence on foreign oil. NewPage Corporation planned to replicate this facility at other NewPage Corporation mills after this first demonstration scale plant was operational and had proven technical and economic feasibility. An overview of the process begins with biomass being harvested, sized, conditioned and fed into a ThermoChem Recovery International (TRI) steam reformer where it is converted to high quality synthetic gas (syngas). The syngas is then cleaned, compressed, scrubbed, polished and fed into the Fischer-Tropsch (F-T) catalytic reactors where the gas is converted into two, sulfur-free, clean crude products which will be marketed as revenue generating streams. Additionally, the Fischer-Tropsch products could be upgraded for use in automotive, aviation and chemical industries as valuable products, if desired. As the Project Independence project set out to prove forest products could be used to commercially produce biofuels, they planned to address and mitigate issues as they arose. In the early days of the Project Independence project, the plant was sized to process 500 dry tons of biomass per day but would

  3. Solar project description. Houston Construction Company single family residence, Eden Prairie, Minnesota March 19, 1982

    NASA Astrophysics Data System (ADS)

    The Houston Construction Company solar energy system is designed to provide 62 percent of the space heating and domestic hot water energy requirements for a single-family detached residence containing 1796 square feet. The residence is in Eden Prairie, MN. Energy collection is accomplished by 468 square feet of Solaron flat-plate collectors which face south at an angle of 60 degrees from the horizontal. air is the medium for transfer of solar energy from the collectors to either the conditioned space or storage. Storage is a 314 cubic foot bin containing approximately 24,000 lbs of crushed rock located in a utility room. when solar energy is inadequate to satisfy the requirements of the space heating subsystem, auxiliary thermal energy is supplied from an 80,000 Btu per hour natural gas furnace. Domestic hot water is provided by a 30,000 Btu per hour natural gas water heater if the solar contribution is insufficient.

    Toward the understanding of fluid motions of planetary atmospheres and planetary interiors by performing multiple numerical experiments with multiple models, we are now proceeding ``dcmodel project'', where a series of hierarchical numerical models with various complexity is developed and maintained. In ``dcmodel project'', a series of the numerical models are developed taking care of the following points: 1) a common ``style'' of program codes assuring readability of the software, 2) open source codes of the models to the public, 3) scalability of the models assuring execution on various scales of computational resources, 4) stressing the importance of documentation and presenting a method for writing reference manuals. The lineup of the models and utility programs of the project is as follows: Gtool5, ISPACK/SPML, SPMODEL, Deepconv, Dcpam, and Rdoc-f95. In the followings, features of each component are briefly described. Gtool5 (Ishiwatari et al., 2012) is a Fortran90 library, which provides data input/output interfaces and various utilities commonly used in the models of dcmodel project. A self-descriptive data format netCDF is adopted as a IO format of Gtool5. The interfaces of gtool5 library can reduce the number of operation steps for the data IO in the program code of the models compared with the interfaces of the raw netCDF library. Further, by use of gtool5 library, procedures for data IO and addition of metadata for post-processing can be easily implemented in the program codes in a consolidated form independent of the size and complexity of the models. ``ISPACK'' is the spectral transformation library and ``SPML (SPMODEL library)'' (Takehiro et al., 2006) is its wrapper library. Most prominent feature of SPML is a series of array-handling functions with systematic function naming rules, and this enables us to write codes with a form which is easily deduced from the mathematical expressions of the governing equations. ``SPMODEL'' (Takehiro et al., 2006

    NASA Astrophysics Data System (ADS)

    Zvoda, Viktoriya

    Proton radiation therapy is a fast growing form of cancer treatment; it requires a precise knowledge of the dose delivered to the tumor and verification of the correct patient position with respect to the proton beam to avoid damage to critical normal tissues and geographical tumor misses. In existing proton treatment centers dose calculations are performed based on conventional x-ray computed tomography (CT). The goal of the Proton Computed Tomography (pCT) project is provide a fully operational detecting system that allows imaging of the patient (or a phantom) directly with proton CT by measuring the energy loss and trajectories of high-energy protons that traverse the patient. The pCT detector contains the upstream tracking detectors, phantom, the downstream tracking detectors, and a calorimeter. The step-by-step assembly of the pCT NIU Phase 2 Scanner and the subsequent tests and calibration procedures are described in the current thesis.

    This investigation reports on the biochemical and clinical outcomes of a newly created pan-Canadian Prostate Cancer Risk Stratification (ProCaRS) database developed by the Genitourinary Radiation Oncologists of Canada (GUROC). GUROC ProCaRS template-compliant data on 7974 patients who underwent radiotherapy were received from 7 unique databases. Descriptive analysis, Cox proportional hazards, and Kaplan-Meier analyses were performed using American Society for Radiation Oncology (ASTRO) biochemical failure-free survival (BFFS), prostate cancer-specific survival, and overall survival. Multivariable modeling for the primary ASTRO BFFS end point showed that age, prostate-specific antigen, T stage, and Gleason score and components such as hormonal therapy, and radiation treatment (brachytherapy with better outcome than external-beam) were predictive of outcome. Kaplan-Meier analysis of the existing GUROC and new NCCN classification system both showed good separation of all clinical outcome curves. The construction of a pan-Canadian database has informed important prostate cancer radiotherapy outcomes and risk stratification.

    a) To describe the methodology used to construct a deprivation index by census tract in cities, to identify the tracts with the least favorable socioeconomic conditions, and b) to analyze the association between this index and overall mortality. Several socioeconomic indicators (Census 2001) were defined by the census tracts of the following cities: Barcelona, Bilbao, Madrid, Seville and Valencia. The correlations with the standardized mortality ratio (1996-2003), and the dimensionality of the socioeconomic indicators were studied. Finally, the selected indicators were aggregated in an index, in which the results of the factor loadings from extraction of a factor by principal components were used as weighting values. The indicators with the strongest correlations with overall mortality were those related to work, education, housing conditions and single parent homes. In the analysis of dimensionality, a first dimension appeared that contained indicators related to work (unemployment, manual and eventual workers) and education (insufficient education overall and in young people). In all the cities studied, the index created with these 5 indicators explained more than 75% of their variability. The correlations between this index and mortality generally showed higher values than those obtained with each indicator separately. The deprivation index proposed could be a useful instrument for health planning as it detects small areas of large cities with unfavorable socioeconomic characteristics and is associated with mortality. This index could contribute to the study of social inequalities in health in Spain.

    This study uncovered inhibiting factors to cost performance in large construction projects of Malaysia. Questionnaire survey was conducted among clients and consultants involved in large construction projects. In the questionnaire, a total of 35 inhibiting factors grouped in 7 categories were presented to the respondents for rating significant level of each factor. A total of 300 questionnaire forms were distributed. Only 144 completed sets were received and analysed using advanced multivariate statistical software of Structural Equation Modelling (SmartPLS v2). The analysis involved three iteration processes where several of the factors were deleted in order to make the model acceptable. The result of the analysis found that R2 value of the model is 0.422 which indicates that the developed model has a substantial impact on cost performance. Based on the final form of the model, contractor's site management category is the most prominent in exhibiting effect on cost performance of large construction projects. This finding is validated using advanced techniques of power analysis. This vigorous multivariate analysis has explicitly found the significant category which consists of several causative factors to poor cost performance in large construction projects. This will benefit all parties involved in construction projects for controlling cost overrun. PMID:24693227

    The final audit report for remedial action at the Ambrosia Lake, New Mexico, Uranium Mill Tailings Remedial Action (UMTRA) Project site consists of a summary of the radiological surveillances/audits, quality assurance (QA) in-process surveillances, and a QA final closeout inspection performed by the US Department of Energy (DOE) and the Technical Assistance Contractor (TAC). One radiological surveillance and three radiological audits were performed at the Ambrosia Lake site. The surveillance was performed on 12--16 April 1993 (DOE, 1993d). The audits were performed on 26--29 July 1993 (DOE, 1993b); 21--23 March 1994 (DOE, 1994d); and 1--2 August 1994 (DOE, 1994d). The surveillance and audits resulted in 47 observations. Twelve of the observations raised DOE concerns that were resolved on site or through subsequent corrective action. All outstanding issues were satisfactorily closed out on 28 December 1994. The radiological surveillance and audits are discussed in this report. A total of seven QA in-process surveillances were performed at the Ambrosia Lake UMTRA site are discussed. The DOE/TAC Ambrosia Lake final remedial action close-out inspection was conducted on 26 July 1995 (DOE, 1995a). To summarize, a total of 155 observations were noted during DOE/TAC audit and surveillance activities. Follow-up to responses required from the RAC for the DOE/TAC surveillance and audit observations indicated that all issues related to the Ambrosia Lake site were resolved and closed to the satisfaction of the DOE.

  15. Constructing Predictive Estimates for Worker Exposure to Radioactivity During Decommissioning: Analysis of Completed Decommissioning Projects - Master Thesis

    Dettmers, Dana Lee; Eide, Steven Arvid

    2002-10-01

    An analysis of completed decommissioning projects is used to construct predictive estimates for worker exposure to radioactivity during decommissioning activities. The preferred organizational method for the completed decommissioning project data is to divide the data by type of facility, whether decommissioning was performed on part of the facility or the complete facility, and the level of radiation within the facility prior to decommissioning (low, medium, or high). Additional data analysis shows that there is not a downward trend in worker exposure data over time. Also, the use of a standard estimate for worker exposure to radioactivity may be a best estimate for low complete storage, high partial storage, and medium reactor facilities; a conservative estimate for some low level of facility radiation facilities (reactor complete, research complete, pits/ponds, other), medium partial process facilities, and high complete research facilities; and an underestimate for the remaining facilities. Limited data are available to compare different decommissioning alternatives, so the available data are reported and no conclusions can been drawn. It is recommended that all DOE sites and the NRC use a similar method to document worker hours, worker exposure to radiation (person-rem), and standard industrial accidents, injuries, and deaths for all completed decommissioning activities.

  16. Factors affecting construction of science discourse in the context of an extracurricular science and technology project

    NASA Astrophysics Data System (ADS)

    Webb, Horace P.

    Doing and learning science are social activities that require certain language, activities, and values. Both constitute what Gee (2005) calls Discourses. The language of learning science varies with the learning context (Lemke, 2001,1990). Science for All Americans (AAAS, 1990) and Inquiry and the National Science Education Standards (NRC, 2000) endorse inquiry science learning. In the United States, most science learning is teacher-centered; inquiry science learning is rare (NRC, 2000). This study focused on 12 high school students from two suburban high schools, their three faculty mentors, and two engineering mentors during an extracurricular robotics activity with FIRST Robotics Competition (FRC). FRC employed student-centered inquiry focus to teach science principles integrating technology. Research questions were (a) How do science teachers and their students enact Discourses as they teach and learn science? and (b) How does the pedagogical approach of a learning activity facilitate the Discourses that are enacted by students and teachers as they learn and teach science? Using Critical Discourse Analysis (CDA), the study examined participants' language during robotic activities to determine how language used in learning science shaped the learning and vice versa. Data sources included videorecordings of participant language and semi-structured interviews with study participants. Transcribed recordings were coded initially using Gee's (2005) linguistic Building Tasks as a priori codes. CDA was applied to code transcripts, to construct Discourses enacted by the participants, and to determine how context facilitated their enactment. Findings indicated that, for the students, FRC facilitated elements of Science Discourse. Wild About Robotics (W.A.R.) team became, through FRC, part of a community similar to scientists' community that promoted knowledge and sound practices, disseminated information, supported research and development and encouraged interaction of

    Building Information Modelling (BIM) technology is already part of the construction industry and is considered by professionals as a very useful tool for all phases of a construction project. BIM technology, with the particularly useful 3D illustrations which it provides, can be used to illustrate and monitor the progress of works effectively through the entire lifetime of the project. Unmanned Aerial Vehicles (UAVs) have undergone significant advances in equipment capabilities and now have the capacity to acquire high resolution imagery from different angles in a cost effective and efficient manner. By using photogrammetry, characteristics such as distances, areas, volumes, elevations, object sizes, and object shape can be determined within overlapping areas. This paper explores the combined use of BIM and UAV technologies in order to achieve efficient and accurate as-built data collection and 3D illustrations of the works progress during an infrastructure construction project.

    The application of integrated satellite and modern wireless positioning technologies for ubiquitous real-time resources management in large scale civil engineering projects can greatly optimize the time and cost in the construction process, and is now the trend for modern construction project management. As the outdoor conditions of most civil construction sites are open to sky, satellite positioning with the popularly used Global Positioning System (GPS) has been proved to be very efficient and effective. However, the condition in indoor and underground construction site is very complicated due to the fact that different construction activities would be carried out in different congested areas, involving heavy construction plant, equipment, professionals and technical personnel. Nowadays different emerging technologies such as Wi-Fi and ZigBee can be adopted for position and tracking in indoor environments. Nevertheless, under the very complicated construction site conditions these technologies may fail due to movement of human resources and construction plant, variation of metrological conditions, and serious multipath effects of signals. It is considered that Ultra Wide Band (UWB) technology is more suitable for indoor construction site environments. In this paper, a case study on the attempt of integrating GPS with Ubisense Real-time Location System (RTLS) for resources management in an underground railway construction site is discussed. Laboratory and field tests have shown that the RTLS can provide better resources management capability in terms of positioning accuracy and stability than Wi-Fi and ZigBee technologies under complicated construction environments. The test results show that the system can normally achieve better than 15 cm accuracy, and better than 1 m under adverse geometrical site condition. However, the high instrumental set up cost and the requirement for high quality data transmission cable for high precision time synchronization between

    An assessment of highway construction project emissions was performed at five study sites in Dallas/Fort Worth, Texas. Four large scale, multi-year construction projects and one small pavement maintenance project were observed. Several types of information were collected from field trucks, materials trucks, and construction equipment. Vehicles were classified according to MOBILE definitions, and the remaining equipment was classified according to AP-42 definitions. Engine starts and stops were recorded from field trucks, as well as the fuel type used and the initial odometer reading. Materials trucks and construction equipment were observed and their activities recorded. The activity measures recorded were engine starts, operating hours, and the frequency and duration of throttles (transient events). Activity from field trucks, materials trucks, and construction equipment was used to estimate the emissions produced at each study site. These emissions estimates were then placed in perspective by comparing their equivalent vehicle miles of travel (VMT) for the general vehicle fleet in the region. An additional comparison was made by expanding the highway construction activity and resulting emissions over the two-county region and comparing this to the emissions generated from on-road mobile sources.

    National Research Institute for Earth Science and Disaster Resilience ( NIED ) has launched the project of constructing an observatory network for tsunamis and earthquakes on the seafloor. The observatory network was named "S-net, Seafloor Observation Network for Earthquakes and Tsunamis along the Japan Trench". The S-net consists of 150 seafloor observatories which are connected in line with submarine optical cables. The total length of submarine optical cable is about 5,700 km. The S-net system extends along Kuril and Japan trenches around Japan islands from north to south covering the area between southeast off island of Hokkaido and off the Boso Peninsula, Chiba Prefecture. The project has been financially supported by MEXT Japan. An observatory package is 34cm in diameter and 226cm long. Each observatory equips two units of a high sensitive water-depth sensor as a tsunami meter and four sets of three-component seismometers. The water-depth sensor has measurement resolution of sub-centimeter level. Combination of multiple seismometers secures wide dynamic range and robustness of the observation that are needed for early earthquake warning. The S-net is composed of six segment networks that consists of about 25 observatories and 800-1,600km length submarine optical cable. Five of six segment networks except the one covering the outer rise area of the Japan Trench has been already installed. The data from the observatories on those five segment networks are being transferred to the data center at NIED on a real-time basis, and then verification of data integrity are being carried out at the present moment. Installation of the last segment network of the S-net, that is, the outer rise one is scheduled to be finished within FY2016. Full-scale operation of the S-net will start at FY2017. We will report construction and operation of the S-net submarine cable system as well as the outline of the obtained data in this presentation.

    SWINGS was a cooperation project between the European Union and India, aiming at implementing state of the art low-cost technologies for the treatment and reuse of domestic wastewater in rural areas of India. The largest wastewater treatment plant consists of a high-rate anaerobic system, followed by vertical and horizontal subsurface flow constructed wetlands with a treatment area of around 1,900 m(2) and a final step consisting of solar-driven anodic oxidation (AO) and ultraviolet (UV) disinfection units allowing direct reuse of the treated water. The implementation and operation of two pilot plants in north (Aligarh Muslim University, AMU) and central India (Indira Gandhi National Tribal University, IGNTU) are shown in this study. The overall performance of AMU pilot plant during the first 7 months of operation showed organic matter removal efficiencies of 87% total suspended solids, 95% 5-day biological oxygen demand (BOD5) and 90% chemical oxygen demand, while Kjeldahl nitrogen removal reached 89%. The UV disinfection unit produces water for irrigation and toilet flushing with pathogenic indicator bacteria well below WHO guidelines. On the other hand, the AO disinfection unit implemented at IGNTU and operated for almost a year has been shown to produce an effluent of sufficient quality to be reused by the local population for agriculture and irrigation.

    The purpose of this study was to gain insight into the experiences and dynamics of the involvement of research participants in a randomized clinical trial for nicotine vaccination. Participants received an experimental nicotine vaccine or a placebo, in addition to quit smoking medication and counseling. The longitudinal design of this qualitative study allowed us to follow people from their first visit to the trial location until the unblinding of their treatment with either verum or placebo vaccine. The empirical data consisted of 49 semi-structured, in-depth interviews, field notes and memos, and trial documents collected in the Netherlands between 2010 and 2012. Participants' expectations and experiences of the innovative nicotine vaccine were characterized by ambivalence: Although they complied with the research design, throughout the study they tinkered with discourses, objects, and activities to make them serve their individual goals. They made the concepts of nicotine vaccination and placebo treatment meaningful for quitting, reshaped the meaning of research tests and obligatory visits to serve their own personal goals, and introduced a new element into the trial by creating space to discuss problems that might endanger the quit attempt. In short, the participants constructed the clinical study for nicotine vaccination as their own personal lifestyle change project. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Die Evolution hat viele spektakuläre Phänomene hervorgebracht - von der Eleganz des Vogelflugs über die gigantischen Körper der Dinosaurier und die farbenprächtige Vielfalt der Korallenriffe bis hin zu ihrem jüngsten Geniestreich - der menschlichen Kunst. Die schönen Künste - Malerei, Bildhauerei und Architektur, Theater, Tanz, Oper und Filmkunst, Musik und Literatur - Produkte der Evolution? Diese Vorstellung mutet vielen Menschen fremd an, aber wie könnte es anders sein? Denn wenn Charles Darwin recht hat, dann sind nicht nur die körperlichen Merkmale der Menschen als Antworten auf die Erfordernisse des Lebens entstanden, sondern auch ihre geistigen Fähigkeiten und Verhaltensweisen. Im Jahr 1859 hatte er auf den letzten Seiten seines berühmten Buches über die Entstehung der Arten eine kühne Prophezeiung gemacht: Durch die Evolutionstheorie werde es "zu einer bemerkenswerten Revolution in der Naturwissenschaft kommen […]. Die Psychologie wird auf die neue Grundlage gestellt, dass jede geistige Kraft und Fähigkeit notwendigerweise durch graduelle Übergänge erworben wird“ (Darwin 1859, S. 484, 488; Junker 2008).

    Ecological monitoring is a complementary component of the overall environmental management and monitoring program of any Environmental Impact Assessment (EIA) report. The monitoring method should be developed for each project phase and allow for periodic reporting and assessment of compliance with the environmental conditions and requirements of the EIA. Also, this method should incorporate a variance request program since site-specific conditions can affect construction on a daily basis and require time-critical application of alternative construction scenarios or environmental management methods integrated with alternative mitigation measures. Finally, taking full advantage of the latest information and communication technologies can enhance the quality of, and public involvement in, the environmental management program. In this paper, a landscape-scale ecological monitoring method for major construction projects is described using, as a basis, 20 months of experience on the Baku-Tbilisi-Ceyhan (BTC) Crude Oil Pipeline Project, covering Turkish Sections Lot B and Lot C. This analysis presents suggestions for improving ecological monitoring for major construction activities.

  16. Construction of explicitly correlated geminal-projected particle-hole creation operators for many-electron systems using the diagrammatic factorization approach

    The computational cost of performing a configuration interaction (CI) calculation for treating electron-electron correlation is directly proportional to the number of terms in the CI expansion. In this work, we present a diagrammatic projection approach for a priori identification of noncontributing terms in a CI expansion. This method known as the geminal-projected configuration interaction (GP-CI) method is based on using a two-body R12 geminal operator for describing electron-electron correlation in a reference many-electron wave function. The diagrammatic projection procedure was performed by first deriving the Hugenholtz diagrams of the energy expression of the R12 reference wave function and then performing diagrammatic factorization of effective particle-hole creation operators. The projection operation, which is a functional of the geminal function, was defined and used for the construction of the geminal-projected particle-hole creation operators. The form of the two-body R12 geminal operator was derived analytically by imposing an approximate Kato cusp condition. A linear combination of the geminal-projected one-particle one-hole and two-particle two-hole operators were used for the construction of the GP-CI wave function. The applicability and implementation of the diagrammatic projection method was demonstrated by performing proof-of-concept calculations on an isoelectronic series of 10 electron systems: CH4,NH3,H2O ,HF , and Ne . The results from the calculations show that compared to conventional CI calculations, the GP-CI method was able to substantially reduce the size of the CI space (by a factor of 6-9) while maintaining an accuracy of 10-5 Hartrees for the ground-state energies. These results demonstrate the ability of the diagrammatic projection procedure to identify noncontributing states using an analytical form of the R12 geminal correlator operator. The geminal-projection method was also applied to second-order Møller-Plesset perturbation

  2. Jiangsu coastal highland reclamation and its wetland ecological construction-a case analysis of the Tiaozini reclamation project

    NASA Astrophysics Data System (ADS)

    Yu, Meixiu; Xu, Xianghong

    2017-04-01

    Reclamation is one potential solution for the increasing demand of new land for living and development. In past centuries, many coastal countries, such as the Netherlands, UK, Japan, South Korea and Singapore, had exploited extensively sea enclosing and reclamation fordefense against storm surges,agricultural and industrial development, as well as for coastal city expansion along the coast. China has continuously reclaimed coastal sea areas from the 1950s. With rapid economic development and increasing population in coastal areas during recent decades, reclamation has been regarded as an effective measure to resolve the land shortage as cities and industries expand, particularly in South-East coastal areas. Jiangsu province, located in East China, has a similar amount of land territory area to the Netherlands, however, its population is almost fivefold instead. Since its coastal area generates large amounts of tidal flat resources due to its unique hydrodynamic and geomorphic conditions, coastal reclamation plays a vital role in guaranteeing the food security for the Jiangsu Province or even the whole nation. The Tiaozini Reclamation Project (TRP), located between N32.720°-32.882°, E120.894°-120.969°, in Jianggang county of Jiangsu coastal region, with an area of 6,746ha, was reclaimed along the prograding muddy silt coast in 2012. It should be noted that the TRP was reclaimed from theoretical bathymetrical datum of about 4.6m. It is estimated that the shoreline moves towards the sea at a rate of 100m/year and the tidal flat raises at a rate of 5 10 cm/year respectively because of the external tidal flat being continually prograding and drying. After finishing reclamation,the TRP develops with nature: for the dried tidal flat high land,developing ecological agriculture after integrated soil improvement with reducing salt and cultivating fertilizer; for the drying tidal flat,developing ecological fishery by inceasing artificial wetland area; for lower tidal flat

    There appears to be a common network of brain regions that underlie the ability to recall past personal experiences (episodic memory) and the ability to imagine possible future personal experiences (episodic future thinking). At the cognitive level, these abilities are thought to rely on "scene construction" (the ability to bind together multimodal elements of a scene in mind--dependent on hippocampal functioning) and temporal "self-projection" (the ability to mentally project oneself through time--dependent on prefrontal cortex functioning). Although autism spectrum disorder (ASD) is characterized by diminished episodic memory, it is unclear whether episodic future thinking is correspondingly impaired. Moreover, the underlying basis of such impairments (difficulties with scene construction, self-projection, or both) is yet to be established. The current study therefore aimed to elucidate these issues. Twenty-seven intellectually high-functioning adults with ASD and 29 age- and IQ-matched neurotypical comparison adults were asked to describe (a) imagined atemporal, non-self-relevant fictitious scenes (assessing scene construction), (b) imagined plausible self-relevant future episodes (assessing episodic future thinking), and (c) recalled personally experienced past episodes (assessing episodic memory). Tests of narrative ability and theory of mind were also completed. Performances of participants with ASD were significantly and equally diminished in each condition and, crucially, this diminution was independent of general narrative ability. Given that participants with ASD were impaired in the fictitious scene condition, which does not involve self-projection, we suggest the underlying difficulty with episodic memory/future thinking is one of scene construction.

    Based on the data, 32% of accidental cases in Indonesia occurs on constructional sectors. It is supported by the data from Public Work and Housing Department that 27.43% of the implementation level of Safety Management System policy at construction companies in Indonesia remains unsafe categories. Moreover, there are dimensions of occupational safety culture formed including leadership, behavior, strategy, policy, process, people, safety cost, value and contract system. The aim of this study is to determine the model of an effective safety culture and know the relationship between dimensions in construction industry. The method used in this research was questionnaire survey which was distributed to the sample of construction companies either in a national private one in Indonesia. The result of this research is supposed to be able to illustrate the development of the relationship among occupational safety culture dimensions which have influences to the performances of constructional companies in Indonesia.

    The construction industry in Hong Kong increased its safety investment by 300% in the past two decades; however, its accident rate has plateaued to around 50% for one decade. Against this backdrop, researchers have found inconclusive results on the causal relationship between safety investment and safety performance. Using agent-based modeling, this study takes an unconventional bottom-up approach to study safety performance on a construction site as an outcome of a complex system defined by interactions among a worksite, individual construction workers, and different safety investments. Instead of focusing on finding the absolute relationship between safety investment and safety performance, this study contributes to providing a practical framework to investigate how different safety investments interacting with different parameters such as human and environmental factors could affect safety performance. As a result, we could identify cost-effective safety investments under different construction scenarios for delivering optimal safety performance. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Part of a special section on the market performance of industrial minerals in 1992. Production of construction aggregates increased by 4.6 percent in 1992. This increase was due, in part, to the increased funding for transportation and infrastructure projects. The U.S. produced about 1.05 Gt of crushed stone and an estimated 734 Mt of construction sand and gravel in 1992. Demand is expected to increase by about 5 percent in 1993.

  9. Utilization of BIM for automation of quantity takeoffs and cost estimation in transport infrastructure construction projects in the Czech Republic

    The article deals with problematic parts of automated processing of quantity takeoff (QTO) from data generated in BIM model. It focuses on models of road constructions, and uses volumes and dimensions of excavation work to create an estimate of construction costs. The article uses a case study and explorative methods to discuss possibilities and problems of data transfer from a model to a price system of construction production when such transfer is used for price estimates of construction works. Current QTOs and price tenders are made with 2D documents. This process is becoming obsolete because more modern tools can be used. The BIM phenomenon enables partial automation in processing volumes and dimensions of construction units and matching the data to units in a given price scheme. Therefore price of construction can be estimated and structured without lengthy and often imprecise manual calculations. The use of BIM for QTO is highly dependent on local market budgeting systems, therefore proper push/pull strategy is required. It also requires proper requirements specification, compatible pricing database and software.

    One of the most challenging parts of an Environmental Impact Assessment (EIA) is to identify and evaluate severity and extent of project's destructive affects on environment. During this study a new method has been developed to predict environmental impact. For this purpose, remotely sensed images in Qazvin-Rasht Highway area, Iran during years of 2004-2008 were used. Although natural habitats including Fauna and Flora are exposed to destructive affects in different various aspects, natural vegetation cover extent and density was chosen as a main environmental element. Changes in extent and density of vegetation cover can be calculated by change detection algorithms between selected images. In this study maps of vegetation cover in Iran are produced using Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) images with spatial resolution of 15m. Vegetation cover obtained from NDVI index is classified in different species by classification methods. The next step is calculation of changes between pixels of images via existing change detection algorithms. Regression models were developed to predict the project activities impacts on vegetation. Forecast model of environmental effects on Flora can be so helpful in Environmental Impact Assessment of road construction projects especially in variants selection phase. It provides useful information for decision makers to select less harmful corridor to construct.

    This paper presents an analysis of the results of field water infiltration tests of windows and sliding glass door assemblies that were conducted within the last five years. In all cases, the tests were conducted during the new construction process. The tests were performed using ASTM Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Curtain Walls, and Doors by Uniform or Cyclic Static Air Pressure Difference (E 1105). The results show a majority of windows and sliding glass door assemblies fail initial field water infiltration tests, which is compelling evidence that these tests are prudent as part of a new construction process.

  13. Test-retest reliability and construct validity of the ENERGY-child questionnaire on energy balance-related behaviours and their potential determinants: the ENERGY-project

    Background Insight in children's energy balance-related behaviours (EBRBs) and their determinants is important to inform obesity prevention research. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed. Objective To examine the test-retest reliability and construct validity of the child questionnaire used in the ENERGY-project, measuring EBRBs and their potential determinants among 10-12 year old children. Methods We collected data among 10-12 year old children (n = 730 in the test-retest reliability study; n = 96 in the construct validity study) in six European countries, i.e. Belgium, Greece, Hungary, the Netherlands, Norway, and Spain. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC) and percentage agreement comparing scores from two measurements, administered one week apart. To assess construct validity, the agreement between questionnaire responses and a subsequent face-to-face interview was assessed using ICC and percentage agreement. Results Of the 150 questionnaire items, 115 (77%) showed good to excellent test-retest reliability as indicated by ICCs > .60 or percentage agreement ≥ 75%. Test-retest reliability was moderate for 34 items (23%) and poor for one item. Construct validity appeared to be good to excellent for 70 (47%) of the 150 items, as indicated by ICCs > .60 or percentage agreement ≥ 75%. From the other 80 items, construct validity was moderate for 39 (26%) and poor for 41 items (27%). Conclusions Our results demonstrate that the ENERGY-child questionnaire, assessing EBRBs of the child as well as personal, family, and school-environmental determinants related to these EBRBs, has good test-retest reliability and moderate to good construct validity for the large majority of items.

    1988-01-01

    An overview is presented of the Automated Software Development Workstation Project, an effort to explore knowledge-based approaches to increasing software productivity. The project focuses on applying the concept of domain specific automatic programming systems (D-SAPSs) to application domains at NASA's Johnson Space Flight Center. A version of a D-SAPS developed in Phase 1 of the project for the domain of space station momentum management is described. How problems encountered during its implementation led researchers to concentrate on simplifying the process of building and extending such systems is discussed. Researchers propose to do this by attacking three observed bottlenecks in the D-SAPS development process through the increased automation of the acquisition of programming knowledge and the use of an object oriented development methodology at all stages of the program design. How these ideas are being implemented in the Bauhaus, a prototype workstation for D-SAPS development is discussed.
