The Berth 3 Extension is the fourth phase in the replacement of an aging wooden pier with a concrete structure composed of prestressed piles and deck panels. This phase included the installation of prestressed concrete fender piles along the 1700 ft. length of the entire concrete pier. Faced with a marine plastic rub strip, the concrete fender piles replaced the toxic creosote-coated wood piles used in the past. The prestressed fender piles are expected to last longer and have a cheaper life-cycle cost than traditional wood pile fender systems.
