This project is the restoration and realignment of a US Navy Destroyer Slip’s South Quay Wall wharf. The harbor services 34 naval vessels and this project will add full berthing capability for littoral combat ships, U.S. Coast Guard cutters and other smaller ships. The area consist of crane loading, staging area with guard house, necessary port docking systems, and bulkhead. The restoration encompasses approximately 540 LF of new bulkhead that is a separate standalone structure seaward of the existing bulkhead in the wharf and the addition of a new combination king pile and steel sheet pile (SSP) anchored bulkhead system. To fill the void between the new and existing bulkheads, we added approximately 12,000 cubic yards of select engineered backfill and topped with an asphalt wearing surface. All berthing and mooring systems were replaced, to include installation of ladders, foam filled fenders and low double bitt bollards. Site civil work at the wharf includes removing/milling the existing asphalt pavement, resurfacing the project area to support crane operations, and realigning the security fence. Existing storm drains removed and replaced from catch basin to outfall. New installation of ship connections to water, electrical, oily waste and sanitary sewer utilities. New construction of utility housing of two sets of igloos and hotel stations, pedestrian turnstile and vehicular gate. Demolition of existing building was also included along with disconnection and removal of associated utilities.
