building application and thermal performance of vacuum insulation panels vips in canadian subarctic climate
Energy and Buildings, 2014Co-Authors: Phalguni Mukhopadhyaya, Doug Maclean, Juergen Korn, D Van Reenen, Sudhakar MolletiAbstract:Abstract Vacuum insulation panels (VIPs) have thermal resistance values, at the center of the panel, up to 10 times or more than those of conventional thermal insulation materials. In Canada, known for its predominantly extreme cold climate, the potential to apply VIPs in the building construction industry is estimated to be enormous, particularly with the introduction of the new 2011 National Energy Code of Canada for Buildings (NECB 2011). VIPs can play a major role in Canadian buildings to meet energy requirements of the NECB 2011. However, the lack of long-term performance credentials and various Constructability issues are among the major barriers for mass application of VIPs in the Canadian construction industry. This paper presents the design strategy, construction details, instrumentation and thermal performance monitoring observations of a VIP retrofitted wall system in Yukon, located in Northern Canada. Experience gained from the construction process and available thermal performance data over a period of three years provide encouraging indicators for the Constructability and long-term thermal performance of VIPs in Canadian subarctic weather.

assessing state transportation agency Constructability implementation
Journal of Construction Engineering and Management-asce, 2005Co-Authors: John A Gambatese, James F Mcmanus, Phillip S DunstonAbstract:Although guidance is available for state transportation agencies to establish Constructability review processes (CRPs), nationwide implementation has been slow due, in part, to a lack of clarity regarding related costs and benefits and a perception that CRPs are resource intensive. This study funded by the National Cooperative Highway Research Program reveals that while numerous states have attempted implementation in various forms, obstacles have frequently either hindered or halted progress. Four elements appear to be essential for the successful implementation and continuance of a CRP: (1) institutionalization of the CRP Champion, (2) an emphasis on a quality-driven as opposed to a schedule-driven design process, (3) clear yet flexible guidelines for executing Constructability reviews across the broad range of project types and sizes, and (4) a vehicle for meaningful expert input from construction contracting professionals. A benefit-cost model, founded on the proposition that CRP implementation provides efficiencies that result in significant cost and schedule reductions, is demonstrated using case studies. A need for more precise identification of costs and quantification of benefits is noted.

Constructability a quality improvement approach to transportation projects
Transportation Research Record, 1997Co-Authors: John A Gambatese, James F McmanusAbstract:Pressures to develop transportation projects that are biddable, buildable, and maintainable may be greater today than ever before. As a result, many transportation agencies are concerned about the Constructability and quality of design documents for roadway facilities. The Washington State Department of Transportation has performed a research study to develop a Constructability review process (CRP) to improve the Constructability of its projects. The CRP is composed of Constructability reviews at various prescribed points in the project time line. The reviews incorporate Constructability checklists and planned meetings among all of the disciplines involved. Implementation of the CRP is expected to reduce the number of construction change orders, the total cost of change orders, construction and maintenance staff, and the amount of resources and to lead to a “zero addendum” bid phase.
