Chevron Long Wharf Causeway/Trestle Seismic Upgrade?- Richmond, Calif.
For this project 244 steel pipe piles were driven through 122 holes cut in the existing causeway deck. The falsework and side forms were installed below the causeway for new concrete bent caps at each cluster of four piles. Six existing causeway expansion joints were demolished and rebuilt to allow for greater movement during a seismic event. A new pipe trestle was made of steel beams and 609 pony bents and pipe supports.
