EMI served as the geotechnical engineer, representing the project owner for the new Gerald Desmond Bridge in the Port of Long Beach, California. The final design of the bridge is being delivered through a design-build contract. The project consists of a new six-lane cable-stayed bridge spanning a channel 800 feet wide and a minimum vertical clearance of 185 feet above water level to allow passage of next-generation container ships.

As this bridge is located close to the Palos Verdes Fault, seismic bridge design constituted a very challenging aspect of this project. The seismic design included response spectrum and time-history analyses for two levels of design eartquakes. EMI provided all geotechnical and earthquake engineering tasks including geotechnical investigation, development of seismic design criteria, preliminary foundation design recommendations for a design-build procurement as well as the design reviews during bridge construction.
