Transbay Tower
Rockefeller Group Development Corporation
San Francisco, CA

CMA is the San Francisco project management representative teamed with Rockefeller Group Development Corporation and SOM for the design and development proposals for the new Transbay Tower.

Signaling a new era for the city of San Francisco, SOM’s design for the new Transbay Transit Center will preserve and enhance the exceptional qualities of the City—the beauty of the light, climate, topography, bay, and City—as well as its people, while embodying a potent belief in the region’s future. The Center consists of two defining elements: the Transit Terminal, which defines the urban transportation facility for the 21st Century, and the Transit Tower, which serves as the beacon for the new center and will act as an economic and cultural catalyst for the neighborhood and the City.

SOM’s 1,375-foot-high, mixed-use Transbay Tower is equally bold. Its first full floor lifts 100 feet above a full-block urban plaza at Mission Street, creating a civic portal to the Transbay Hall. Its uses include retail, cultural, office space, a boutique hotel, condominiums, and, at the top, a publicly accessible sky room. The tower’s tapered, turning structure is unique among U.S. skyscrapers. Its form, which unfolds as it reaches the sky, gracefully accommodates the different uses held within. Above the sky room are two state-of-the-art wind turbines that, combined with its photovoltaic crown, reduce annual mechanical electrical consumption by 74%. In addition to the proposed opportunity site, the SOM/RGDC project includes a partnership with the San Francisco Museum of Modern Art, which will provide a major digital arts program, and with the California State Library, which will lend its Sutro Collection. These partnerships add an extraordinary cultural dimension to what is already an advanced work of transportation infrastructure.
