The Parcel A office building captures the awe-inspiring shipyard scale of San Francisco’s historic industrial waterfront, while creating a workplace environment that is humane and human-scaled from the inside out. An emphasis on biophilia and the beauty of the exposed mass timber structure guided the design, which incorporates abundant daylight, access to fresh air, and natural materials. The design makes quality and craft visible, from the beveled piers that catch light from different angles on each floor to the transparent, inviting ground floor lobby and retail spaces. The 6-stories of above grade superstructure consists of CLT and concrete topping slab spanning between glulam beams and supported by glulam columns. The superstructure lateral system consists of steel buckling-restrained braced frames. The roof supports two penthouses, in addition to several MEP units. The L1 transfer floor consists of a post-tensioned concrete slab with post-tensioned concrete transfer girders. The L1 slab and beams are supported by concrete columns and a basement concrete perimeter wall. The south portion of the building is supported by a mat foundation resting directly on bedrock. The northern portion of the building is supported by pile caps and piles with a spanning basement structural slab.
