What would help most to use PBES? Prefabricated Bridges to Accelerate ConstructionSurvey to Sample State Bridge EngineersQuestion: Barriers to routinely install PBES in hours ordays?Example Responses (lack of education / training /experience): Education of DOT and contractors. Training. Contractors are reluctant to bid on technologies,methods, or equipment with which they areunfamiliar. Engineers do not feel they are knowledgeable ondesigning projects for rapid construction.Exposure to / experience with large prefabsystems. Prefabricated Bridges to Accelerate ConstructionSurvey to Sample State Bridge EngineersQuestion: What would help most to use PBES?Example Responses (education / training / moreprojects): Training for contractors and owner inspectors(shop and field site). Projects in the U.S. that demonstrate rapid bridgeinstallation would provide examples and increaseinterest by State DOTs. More knowledge gained through experience. Education for design engineers and contractors. Information on how and why. 123doc.vn
