Salesforce Tower 1
A Cesar Pelli inspired work.
The footprint of Salesforce Tower rests on land fill near San Francisco's original waterfront, an area prone to soil liquefaction during earthquakes. To account for this seismic risk, the tower uses a design that is modeled to withstand the strongest earthquakes expected in the region. Its foundation includes 42 piles driven down nearly 300 feet (91 m) to bedrock and a 14-foot (4.3 m) thick foundation mat.
Below:
Designed by Pelli Clarke Pelli Architects (PCPA), the Transbay Transit Center is about 1,430 feet (440 m) long and 165 feet (50 m) wide. Shown is the main entrance to the Grand Hall, located at Mission and Fremont Streets. The outer "skin", made of white aluminum, is perforated in the pattern of a Penrose tiling.
The transit center was abruptly ordered closed on September 25, 2018 following the discovery of a crack in a steel beam supporting the rooftop park. A crack in a second beam was found the next day. As of May 2019 repair of these beams is complete.
