San Diego, CA — Kleinfelder was recognized with two Outstanding Project Awards for the Georgia Street Bridge Over University Avenue Rehabilitation and Seismic Retrofit project for the City of San Diego. The Awards were presented at ASCE San Diego Section’s Annual Awards Luncheon.
ASCE San Diego Section recognized the project for award in the Seismic Retrofit category, which acknowledges projects that primarily focus on seismic retrofit design and construction of existing buildings and infrastructure, and which showcase advances and/or innovation in design. The project also received the top award in the Historical Renovation category, which recognizes projects that focus on the renovation/restoration design and construction of a historical civil engineering project, building, structure or facility.
As the lead consultant and bridge designer, Kleinfelder worked with the City of San Diego (Client/Owner) to develop a full retrofit plan as well as address other rehabilitation efforts for the bridge, which was originally constructed in 1914. The reconstruction plan was developed to alleviate structural deficiencies, seismic vulnerability and extensive deterioration, as well as maintain the bridge’s historic integrity.
Squeezing a modern seismic design into the framework of a historic arch bridge was no easy feat. Kleinfelder utilized innovative techniques including integration of existing arch ribs into the final structural system, hydrodemolition of cover concrete, and self-consolidating concrete with reinforcing fibers. The result was an innovative design that balanced safety, historic preservation, cost, and seismic performance, while accomplishing the goal of restoring the aging landmark to its original glory.
In addition to being recognized by ASCE San Diego as an Outstanding Project Award winner, the Georgia Street Bridge project also received the ACEC California Honor Award, which Kleinfelder, alongside the City of San Diego, accepted in February.
