Port of Long Beach Marine Maintenance Dock Facilities at Pier D, Berth 48, Project

The Port of Long Beach (POLB) Maintenance Division is responsible for public infrastructure within the port complex, including the potable water system, the sewer and pumping stations, storm water pumping and drainage systems, street lighting, docks and wharves, maintaining the navigable waterways free of debris and obstructions, minor street repairs, landscape and grounds maintenance and cleanup, traffic accident cleanup and damage repairs of the port’s equipment, fleet of vehicles and boats, in-house commercial dive team, and buildings that are not assigned to tenants. Part of the Maintenance Division is the Harbor Marine Maintenance Group (the group), which is the team responsible for maintaining the 4,600 acres (18.6 km²) of waterfront assets. The in-house commercial dive team is part of the group. A two-story administration building was upgraded at Pier D, Berth 48, for the group’s use as the dive team needed a docking facility for their small craft vessels. A floating dock was designed and built to facilitate the team’s safe and efficient operations. This paper presents the project constraints, the dock alternatives considered, the design/construction lessons learned, and the innovative features that resulted in successful project completion.
