Z--Golden Gate National Recreation Area - Stabilize Alcatraz Wharf

Work will include repair of the historic, steel-cased concrete piles, concrete beams, and concrete slabs. These elements are in fair to poor condition, with varying degrees of damage. Two new seismic resisting elements will be installed to bring the wharf up to a seismic Risk Category III structure. Concrete repairs and seismic improvements will be undertaken in a single phase of construction. Subject to availability of funds of a separately tracked project, GOGA 312663A Repair Finger Pier and Moveable Gangway at Alcatraz Island, a set of construction contract options will also include repairs to the finger pier. The finger pier is connected to/an extension of the concrete wharf. The project will repair or replace the existing wooden fender and bearing piles, cross bracing, gangway ramp landing and motorized pulley system, to match the existing.
