Salesforce Tower
The Salesforce tower is an iconic addition to the San Francisco city skyline. At over 1,070 feet, it is the tallest building in the Western United States. The unique structure consists of a glass and steel curtain wall, surrounding a structural steel frame, which surrounds a reinforced concrete core. The towers’ 5th connects to the Bay Area Transit Center’s rooftop public park that extends four city-blocks long, and is home to native trees, leafy gardens, fountains, public art, and cultural events. Situated in an area prone to liquefaction, 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. The building also features the tallest piece of public art in the world at its crown, featuring a rotating set of abstract media by artist Jim Campbell that illuminates the city skyline each night.

Design Features

After the anchor bolt foundations are poured, BSI field verifies the location of the bolts as they relate to the design drawing locations. We deliver a graphic report of our findings indicating the horizontal location of bolt centers to the template centers, along with the complete pattern centers. Vertical data is also provided.

As the columns are erected, we survey the horizontal position of the column. We provide the location to the design grid, the column itself, or both. Clients receive a report with data indicating the top of column location.

As the columns are erected, we survey the vertical position. BSI provides clients the information needed to indicate the top of column elevation including the delta to design elevation for projects.
