A platform for research: civil engineering, architecture and urbanism
The research completed under this contract has resulted in the development of five different precast structural superstructure types with details completed which are suitable for inclusion in a set of contract plans. The five types are: (1) Precast Concrete Box Beams, (2) Prestressed Concrete PCI Box Beams, (3) Precast Concrete Double Stem Tee Beams, (4) Precast Concrete Solid Slabs, and (5) Precast Concrete Voided Slabs. It was determined that one of the primary reasons that the alternates were not competitive with the standard structure was that the precast producers were not willing to invest in new forms and associated production hardware which might be used for only one job. It is recommended that some means be found to separate this cost from the contract, thus allowing a true comparison of the new bridge types to be made.
