Facts Regarding the Tallest Skyscraper in San Francisco


One recent project The Conco Companies provided a range of concrete services for is the Salesforce Tower in San Francisco.  Now the tallest and most expensive building in the city as well as the tallest occupied floor west of Chicago, the Salesforce is close to completion.  Scheduled to open in early 2018, the project developer’s, Boston Properties reports that nearly 700 construction workers are on site every day, working around the clock to finish the tower.

Another interesting detail about the 61-story skyscraper is it was originally named the Transbay Tower but Salesforce bought both the naming rights and the lease of 30 floors in the tower in a $560 million over 15 and a half year deal.  Other companies that will share space in the 1.4 million-square-foot building include Bain & Company, Accenture, and CBRE, a real-estate group.  WeWork, the newest tenant, just completed a deal to lease three floors of the tower, which will become their second headquarters.  Their first is in New York City.

The project’s General Contractor, Clark Construction want to let the building’s neighbors know that the tower is firmly anchored to bedrock by 42 load-bearing piles that go down more than 300 feet below grade.  In fact it is the first commercial office building in California to be designed with such an advanced level of seismic safety.

Along with the 13 ft. high ceilings and continuous 10 ft. tall windows on each floor, metal automated sunshades will adjust during the day to maximize sunlight as well as protect the offices from overheating.   Additionally the tower will offer direct access to the Transbay Transit Center, which will be just next door once it opens.

In terms of the number of people working in the tower, Salesforce alone expects to have 10,000 of their employees in the tower.  This is approximately a third of the company’s workforce.  The top two floors (60 and 61) are part of Salesforce’s lease and they say they will let out the top floor for free to nonprofit groups and nongovernmental organizations.
