Develop New Methods for Material Acceptance on Design-Build Projects
| 项目名称： | Develop New Methods for Material Acceptance on Design-Build Projects |
| 摘要： | The Federal Highway Administration (FHWA) has allowed state departments of transportation (DOTs) to use contractor material tests for acceptance, as long as they are validated by owner tests in accordance with FHWA Technical Advisory T6120.3, Use of Contractor Test Results in the Acceptance Decision, Recommended Quality Measures, and the Identification of Contractor/Department Risks, which is based on 23 CFR 637�Construction Inspection and Approval. On design-build projects, this process has led to a very complicated quality assurance program that requires contractor quality control and quality assurance (QC/QA) material testing laboratories and owner verification, independent assurance, and referee labs. The current process is time consuming, expensive, and reveals little about the quality of the product. This project shall expand on previous related work by the research team and: (1) Conduct a review of past and current studies for construction material acceptance. (2) Identify current practices and innovative strategies or methods for construction material acceptance on design-build projects. (3) Identify benefits, costs, and risks to highway agencies, contractors, and the traveling public for not having appropriate construction material acceptance on design-build projects. (4) Evaluate the various strategies and methods for accepting materials on design-build projects based on risk and manpower limitations. (5) Develop new strategies or methods for construction materials acceptance on design-build projects. (6) Incorporate the results of this project into Texas Department of Transportation's (TxDOT�s) process on material acceptance and the training of project managers and other staff. (7) Conduct a Material Acceptance for Design-Build Enhancement Workshop to facilitate implementation of research results. |
