• Abstract:
  As part of a project with the Iowa Department of Transportation to develop a set of standards for single­ span prefabricated bridges in the 30' - 70' span range for use by Iowa counties, HDR provided recommendations for a preferred system utilizing precast concrete voided concrete slab beams for the shorter span ranges and precast/prestressed concrete box beams for longer span ranges. The development of the standards has been divided into three phases. Phase 1 developed the concept, the recommendations, and initial details, and Phase 2 of the project was established to provide consultation on testing for the recommended system. This Phase 3 of the project which focused on refinement of the concept, some additional parametric studies and final design/development of the standards.
