Building a Foundation in the Transbay

Developers of Park Tower Begin Vertical Construction After Pouring Immense Foundation Slab

SAN FRANCISCO – December 5, 2016 – With the 11,000 cubic yard foundation slab now laid for Park Tower at Transbay (the size of almost four Olympic swimming pools), the project’s partners, The John Buck Company, Golub, and MetLife, are on schedule and will go vertical with construction of the 43-story, state-of-the-art office tower that will soon be part of San Francisco’s skyline.

The last of 80 truckloads of concrete were poured into the 40-foot deep hole at Beale and Howard Streets at around 10 p.m. PT Saturday night, completing the foundation with a 12-foot-thick concrete slab. Park Tower will have one of the most robust foundations in San Francisco; along with the 11,000 cubic yards of concrete, construction crews wove four million pounds of rebar into the foundation, which is anchored 25 feet into bedrock.

When completed in the first quarter of 2018, Park Tower will offer 750,000 square feet of prime office and retail space with unchallenged views of the San Francisco Bay and downtown. In fact, 70 percent of the floors boast views of the Bay.

Park Tower is pre-certified Leadership in Energy & Environmental Design (LEED) Gold with advanced building systems and a 25 percent stronger, reinforced ductile concrete core, making it capable of withstanding major earthquake activity.

The building features 14 exclusive sky decks, offering outdoor work and leisure space for tenants. There is also more than 50,000 square feet of public space within the project, which sits adjacent to the future Transbay Terminal and its planned city park. The development is located across the street from the temporary transit center and offers easy access to BART, Muni, ferries, and on/off ramps to the Bay Bridge.

Park Tower is being offered for lease now by Christopher T. Roeder, Wes Powell and Steve Anderson of JLL.
