Complete dock structure with crane rail supported on 88 driven and socketed piles. The replacement project is directly adjacent to the existing pier and involves demolition of portions of the existing pier and construction of the new pier and breasting dolphins.
Extensive overburden and complex soils conditions consisting of deep sands, silts, and clays required drilling. Pile installation called for large diameter pipe piles with assorted pile tips, rock anchors, rock sockets, and anodes. Most of the piles are 36in dia. up to 175-ft long driven to bedrock and then socketed 15-ft into bedrock. The pile schedule included 7,570 LF of 36-in dia. x 1.00t wall, 6,606 LF 30-in dia. x 0.50t to 1.00t wall, and 2,495 LF 26-in x 0.75t wall.
Project also involved the installation of 2 rock anchored dolphins and steel fender piling. The piling is being accomplished using a combination of land and barge mounted equipment. Vibratory, impact, and drilling equipment were used on this project.
