Now a unique seven-story office building, 501 Second Street was originally built as a warehouse in 1925. Located along the Second Street Corridor, the building underwent a complete renovation in 1985 including a seismic upgrade and the addition of three floors and a terrace. Now part of the rapidly expanding South of Market (SOMA) District, this building is considered one of the highest quality office spaces in the area.
ARG Conservation Services was retained to assess the causes of the concrete deterioration and manage the repair of damaged concrete on the decorative architectural features of the façade. The treatment began with the testing of various techniques in order to identify a successful process for repair. This ensured that the conservation work would match the original surface profile and texture of the façade. The patchwork blends harmoniously with the original surface of the building, reestablishing an integrated visual aesthetic and helping to prevent further deterioration.
