Construction is underway for the Transbay Transit Center, San Francisco's new state-of-the-art, multi-modal transportation hub designed by Pelli Clarke Pelli Architects. Scheduled to open in 2017, this landmark glass and steel structure will connect the city and the Bay Area via 11 public transit systems.  

The Transbay Transit Center will also be the San Francisco station for California High Speed Rail and the first new high-speed rail station in the United States. Conceived as "the Grand Central of the West," the building is designed in the spirit of the great train stations of the world. The highly sustainable and accessible building will be distinguished by dramatic, light-filled spaces and a 5.4-acre rooftop park.

The Center is designed to be graceful, luminous, welcoming and safe. An exterior glass wall with undulating forms like petals of a flower will create a civilized presence on the street. These undulations also respond to the building's robust concrete and steel structural system, which is engineered for performance in the event of severe earthquakes.

Targeting LEED Gold, the Transbay Transit Center will use multiple sustainable design strategies. The rooftop park will absorb and filter pollutants through its trees, landscape and water management system. Beneath the Center, a massive geothermal heat exchange system will be built into the building's foundation.

(Running the length of nearly five city blocks, it will be one of the largest geothermal installations in the world.) To further reduce energy consumption, the building will be naturally ventilated and most spaces will be naturally lit. Finally, the building will manage stormwater and reuse greywater. The water reuse and conservation system will save 9.2 million gallons per year (the equivalent of 19 Olympic-sized swimming pools).

Intended to be a destination for both transit users and the general public, the building will offer street-level shops, cafés and public promenades. In addition, the architecture integrates works by significant contemporary artists, including James Carpenter, Julie Chang, Jenny Holzer, and Ned Kahn.   For more information, visit
