Project Description:
Triplett-King & Associates provided the value engineering design services to replace approximately 1,529 feet of multi-span dual bridge structures with a single 190 ft. simple span structure and replace costly concrete retaining walls with decorative, soldier pile and panel walls. The long simple span bridge design required 78 inch deep structural steel plate girders and MSE high wall abutments to provide the necessary horizontal clearances for the underlying roadway. The MSE and extensive retaining walls were designed with multiple tiers for landscaping treatments and contain decorative palmetto tree reveals in the wall panels for added aesthetics. This value engineering option provided a functionally adequate and aesthetically pleasing structure with significantly lower maintenance costs at a construction savings of $2.8 million to the SCDOT.
This project was awarded the 2005 Engineering Excellence Transportation Award sponsored by American Council of Engineering Companies of South Carolina.
