State Bar Association

The seismic upgrade project at the State Bar building in San Francisco was a challenging job that mostly installed at night. The work paid off. The American Association of Structural Engineers notified General Contractor Turner Construction that the project has won the "2007 Best Seismic Upgrade Award". Olson's scope was installing the custom WT frames and the unbounded braces purchased from Japan. Olson also installed the custom cladding around the frames and braces on the ground floor.
