Bridges Structural Investigation

Five bridges were examined to identify specific information relevant to load rating. A combination of load testing and GPR were used to determine structural performance and develop as-inspected drawings. BDI performed GPR, Schmidt Hammer Tests, and Reinforcement investigation on three concrete bridges (two RC slabs, and one PS/C double T-bridge), and on the RC bridge decks of two steel girder bridges. BDI also performed loaded testing on the two steel girder bridges to determine the level composite action. All of the bridges were single span. BDI also developed as inspected drawings with reinforcement plans.
