San Francisco, California

Malcolm is under contract to provide temporary support of excavation for 500 Folsom in San Francisco, CA, a proposed 570-unit apartment building located within the Transbay Development Area south of the Financial District in Downtown San Francisco. The building has a height of 440 feet. The project requires 8 floors of below-grade parking developed within a 72-foot deep excavation. Due to the steeply sloping bedrock, a combination of secant piles and CSM panels will be used for the temporary shoring walls. The excavation will be braced by a combination of internal struts and tie-backs. The project is underway with the demolition of the structure, which will be immediately followed by the foundation work.
