BRAVO 1 PIER REPAIR, Pearl Harbor, HI
Demolition work included removal of the fendering system, including 66 piles, 21,000 square feet of AC paving, approximately 400 linear feet of utility piping to access concrete for repairs, and multiple mooring fittings along the deck. Demolition required lead and asbestos abatement and disposal.
The wharf refurbishment included concrete spall and crack repairs to the top deck, soffit, beams, and walls, as well as pile spall repairs. This concrete work included both concrete and reinforcing steel removal and replacement. As part of the soffit repair process, the existing under-wharf utility systems, which included low pressure compressed air, water, sanitary sewer, and salt water, were removed and temporary piping was provided. The utility piping re-installation included new piping, re-installation of existing valve manifolds, and new pipe hangers as required. New electrical installation included under-deck ductbank and wharf-side power mounds.
85 new 24-inch square concrete fender piles were installed. A new fender system, including chocks, UHMW, backboards, and pneumatic floating fenders, was installed, as well as a permanent floating curtain boom encompassing the continuous length of the berths at this pier behind the new fendering system to prevent floating debris from collecting under the deck and causing damage to the pier structure. New mooring fittings including cleats, bollards, and bitts were installed, which also required new concrete pedestal foundations. Additional enhancements also included extension of deck drains and installation of new drain inlets. Following completion of all deck repair work and AC, pavement marking of the new AC overlay and painting of mooring fittings and railing were completed.
