The boathouse was built as a saltwater pumping station for the Oakland Fire Department in the aftermath of the 1906 Earthquake. In 1914 it was converted to a boathouse. Due to the excessive deterioration of the building, the building was closed and the restoration began by installing a cofferdam around the building to lower the water level so that construction could begin.
Alpha’s work included the removal of soil under the concrete slab to have enough head room to work under the slab and access the top of the concrete piles. The work included concrete spall repairs, cathodic protection, carbon fiber reinforcement to limited sections of the bottom of the concrete slab and concrete girders. We finally coated all concrete areas that will be submerged or close to the water level with epoxy coating.
