Project Description
The project involved several improvements along the waterfront at the Port. This included adding 246 feet of new wharf to extend Berth G236, building new rock dikes, and improving the mooring infrastructure at Berths G232 and G236. The work required demolishing a section of the previous wharf and concrete piles, extensive dredging, and driving approximately 185 new 100-foot-long concrete piles.On the land side, the improvements included adding 2 acres of backlands to increase the terminal’s storage capacity, strengthening the dockside infrastructure to support new, larger ship-to-shore cranes with a longer reach, equipping the wharf for ships at berth to run on shore power, and installing drainage systems, lighting, fencing, signage, and new pavement striping. These enhancements have given the terminal the capability to accommodate the larger ships that are the workhorses of the trans-Pacific trade route.
Major Challenges
The major challenges included working within the constraints of a live shipping terminal, maintaining the project schedule, documenting and disputing extra work related to change orders and design changes, and managing a large number of subcontractors alongside the joint venture partner, Griffith Company.
Project Highlights
Key highlights of the project include trucking and placing over 170,000 pounds of quarry run as fill, including the installation of an underwater rock dike utilizing a Dutra scow, as well as completing four concrete deck pours to finish the primary structural elements.
Project Scope
The project scope included a 246-foot extension of the existing concrete wharf structure at Berth G236, demolition of a portion of the neighboring G235 wharf and the end wall at G236, dredging to deepen the berth extension, construction of a sloped rock dike to extend the backlands, and the installation of new electrical, water, storm drain, and communication utilities, as well as crane rails at the new wharf extension.
