Gap Headquarters - PB&A Inc

Gap Headquarters


The Gap Headquarters excavation sat on the Embarcadero, directly across the street from the San Francisco Bay. The water table was tidal and regularly fluctuated. PB&A, Inc. used 80 ft. long soil cement tangent piles with cross-lot bracings for the shoring design. Shoring contractors, Condon-Johnson Associates, were very successful in maintaining dry excess and a nominal amount of deformation – the maximum deformation was recorded to be ¾ of an in.
