One Rincon Hill, Phase I
One Rincon Hill is an upscale residential development located in the Rincon Hill neighborhood of San Francisco.
One Rincon is a complex project, both structurally and geographically. The 1.3 acre site is immediately adjacent to the San Francisco/Oakland Bay Bridge and surrounding buildings. Phase 1 of the two-phased project included demolishing the sites' existing office building - the famed Bank of America clock tower and parking garage requiring considerable coordination with California Department of Transportation (Caltrans) and the City of San Francisco. Excavation to 55 feet posed specific challenges, including shoring, monitoring movement of the Bay Bridge and developing custom designs for the soil retaining system. Additionally, coordination of the adjacent utilities and neighbors required special care.
Phase I also included the construction of a new, 762,000 square foot, 55-story cast-in-place concrete residential tower that sits above a full-site podium with five levels of below-grade parking (513 spaces) and amenity functions, and a five-story townhouse structure.
Scope included demolition, interior fit-out, landscaping and site work, new building, six passenger and one service elevator, mat footing and spread footing foundation, post-tension concrete, reinforced concrete and steel structure, curtain wall, masonry and window wall external skin, EPDM roofing and high-end finishes.
