400/430 California

Originally built in 1908 and modified in 1967, Olson Steel was involved in the seismic retrofit of 400/430 California Street – a historic bank located in the heart of the Central Business District in downtown San Francisco, by providing the lattice work of new steel, as well as structural steel on the basement, Level 3, and Level 5 of the building. The neighboring tower was connected to the historic bank to prevent the structural failure of the bank.
