 San Francisco - Oakland Bay Bridge: Dismantling the Cantilever Truss


David Piermarini| Operations Manager, Bay Bridge Demolition

California Engineering Contractors, Inc.

The Joint Venture of California Engineering Contractors/Silverado Contractors started the dismantling of the 80 year old Cantilever Span on Labor Day Weekend in 2013.  The dismantling of the spans, which was performed in a sequence referred to as “reverse engineering”, was completed in approximately 20 months.  The Bridge was 382 feet high at its tallest point and nearly mile in length and included over 20,000 tons of steel and 12,000 tons of concrete to be removed.  As the old span was located within a few feet of the new bridge and new bike path, numerous restrictions related to public traffic, the Bay waters, marine and bird life living on and around the old structure had to be considered and adhered to during the removal work. This presentation will address some of the challenging aspects of the work and include a description of the intricate removal procedure which had to address the relieving of the “locked-in forces” of the old spans.

Both California Engineering and Silverado have completed complex demolition projects in the Bay Area over the past few years including the Carquinez Bridge in 2007 and most recently Candlestick Park.
