The San Francisco Transbay development plan consists of three supertall skyscrapers and ten other skyscrapers and highrises proposed in San Francisco. The towers are proposed to fund the replacement of the San Francisco Transbay Terminal in the South of Market neighborhood near the Financial District.[11] The supertalls comprise only three of the 13 towers of the Transbay Project. Five of the 13 towers are part of Renzo Piano's complex and the other eight are Transbay Towers.[12] Two other proposals named 181 Fremont Street and 350 Mission Street are proposed projects part of the Transbay Project.[7]

The skyscrapers will take advantage of Transbay Terminal air rights, and land formerly owned by the state which will no longer be needed for bus ramps.[13]

[edit] Transbay project details

Two of the supertall skyscrapers named Renzo Piano Tower I and Renzo Piano Tower II are set to rise 326 m or 1,070 ft. and contain 80 floors.[8][14][15] The twin supertall terra-cotta towers of the five-tower complex will be located at First and Mission Streets.[14] The entire five-tower complex will be designed by Italian architect Renzo Piano.[14] These buildings will tower 347 feet (106 m) over the Transamerica Pyramid, which is the tallest in San Francisco.[14] Adjoining the twin supertalls are two 900-foot (274 m) towers and one 600-foot (183 m) tower in a dense tower complex said to resemble bamboo shoots.[14][15] Another supertall named Transbay Transit Center & Tower will be attached directly to the replacement Transbay Terminal and this tower will rise on Mission & Fremont Streets. Cesar Pelli's design was chosen by the city of San Francisco on September 20, 2007.[16] Pelli's tower includes a 1,400-foot (427 m) long park on top of the terminal with a 1,070-foot (326 m), 80-story office tower.[2] This design includes wind turbines on the roof and the building will contain 1,300,000 sq ft (121,000 m2) of office space.[2][11] There are seven other towers of the Transbay Project located on nearby blocks ranging from 850+ feet (259+ m) to a modest 300 feet (91 m).[12]

[edit] History

The Transbay Project Towers were proposed along with the replacement of the current, aging Terminal. Early versions of the project had only seven towers with six towers over 300 feet (91 m) tall, and one 550-foot (168 m) tower directly attached to the new terminal.[17] In December, 2005, the tower attached to the new terminal was proposed at 925 feet (282 m).[18] About five months later in May, 2006, the single Transbay Project I tower was proposed at 1,000 feet (305 m), with two additional 850-foot (259 m) Transbay Project towers located near the 1,000-foot (305 m) tower.[17][19] Seven months later, Renzo Piano replaced one of the 850-foot (259 m) towers with a dense five-tower complex with two additional supertalls and several other tall skyscrapers, leading to a total number of thirteen Transbay Project towers.[14] Proposed designs for Transbay Project I, ranging from 1,200 feet (366 m) to 1,375 feet (419 m) were presented to the city on August 6, 2007 by the three competing architectural firms or architects. In addition to the winning design by Pelli Clarke Pelli Architects, plans were submitted by Skidmore Owings & Merrill (SOM) and Richard Rogers.[11] The SOM plan consisted of a 1,200-foot (366 m), 93-story twisting tower with a 175-foot (53 m) glass crown for a total height of 1,375 feet (419 m).[11][20] On the ground, there would be a 70-foot (21 m) wide by 103-foot (31 m) tall open-air passage that would lead commuters into the new Transbay Terminal.[11] Rogers' plan consisted of a 1,118.5-foot (341 m) mixed-use tower with exposed elevators. A 168-foot (51 m) steel-framed structure on the roof of this 82-story building would push the total height to 1,286.5 feet (392 m).[21] All three designs included wind turbines on the roof.[11] The SOM plan was later on reduced to 1,070 feet in height due to the concerns about shadows, and the FAA.[22]
