Project Description

Senior geotechnical consultant on the Maumee River Crossing Cable-Stayed Bridge Project in Toledo, Ohio. Developed and implemented drilled shaft acceptance criteria during construction. The effort included analyzing cross-hole sonic logging data to assess drilled shaft integrity. The drilled shafts were 2.5 m in diameter, fully cased and drilled using oscillator and rotator equipment. Numerical design support was provided to assess constructability and to evaluate skin friction, bearing capacity, and expected settlement in fractured rock. Design support was also provided to assess mitigation designs where defects were identified in the constructed drilled shafts.
