This building is the newest office building in San Francisco’s North Financial District. Because the site contains the landmarked, Mining Exchange Building, the construction underwent a more stringent review process. Construction was allowed above, around and under the building but not on it. The tower had to be raised into the air so crews could dig 30 feet underneath for the foundation of the new office building. FCI provided a 3 box core with 12 cylinders coordinated and controlled by our patented Tru-tech control system.
