Potrero Power Station A Building

The Potrero Project is located in San Francisco’s Central Waterfront and is part of a large 30-year multiphase development for additional growth of land use such as residential, commercial, and parks. Our contracted work included the structural steel shoring retrofit of the Historic Potrero Power Station A Building. Partnering with Plant Construction, Olson Steel fabricated and erected the designed shoring system to brace the building’s exterior 48” thick brick walls with (4) rows of jumbo waler beams anchored through the walls. The waler beams interfaced with connecting large pipe braces spanning 60’-0 long to additionally brace the exterior walls on the interior of the building. Five large pipe framed shoring towers were fabricated and erected atop of micro-piles with bracing connected back to the waler beams to laterally brace the entire building. Olson Steel executed the project under budget and ahead of schedule.
