Do you ever wonder what’s beneath the office building you work in?  No, not the parking garage–what the building is constructed on?

Park Tower at Transbay isn’t just San Francisco’s most dynamic major office development—with 14 outdoor sky decks planned that boast sweeping bay views.  It also incorporates state-of-the-art design and construction anchoring the soon to be 605-foot tall tower firmly 25 feet into bedrock.

What will be under Park Tower, other than bedrock?  Construction crews just spent 20 hours pouring 11,000 cubic yards of concrete (that’s the size of almost 4 Olympic swimming pools!). They also installed four million pounds of rebar to create the 12’ thick base slab for the 43-story office tower.




While the foundation isn’t the largest for an office building in the city – in comparison Transamerica Pyramid has a 16,000 cubic yard concrete foundation – it’s definitely one of the best.
