Accelerating the Design and Delivery of Bridges with 3D Bridge Information Modeling: Pilot Study of 3D-Centric Modeling Processes for Integrated Design and Construction of Highway Bridges

This Innovations Deserving Exploratory Analysis (IDEA) project develops and tests a 3D-centric model for an integrated design and construction process for highway bridges. An integrated design of the 3D-centric model was developed and issues with the proposed 3D-centric approach were identified. The work involved building parameter dictionaries for typical medium-span highway bridges, specifying and refining data flow for a completed integrated design, presenting a software demonstration illustrating parameter-driven 3D-centric bridge structure design, and identifying technical and coordination issues. The work also involved detailing of steel plate girders and prestressed precast concrete girders, strands and reinforcement. A prestressed concrete bridge provided by the Pennsylvania Department of Transportation was modeled parametrically in 3D and evaluated by a private contractor. The results and feedback should aid in conducting 3D modeling for a real bridge design and construction project. The final report documents requirements for needed standards and "best practices" pragmatics for 3D-centric approaches and accompanying electronic data interchange for streamlining construction and design processes. The project team has worked closely with the AASHTO Bridge Committee as a part of the implementation efforts for this IDEA product.
