Project Detail

This waterfront project is located at 10th Avenue Marine Terminal and involved a major seawall repair around the entire 4,639lf waterfront perimeter of the facility. The existing cyclopean seawall averaged 50' tall with the toe under 38' of water. It took over 15,000 diver manhours to complete the underwater portions of the work. The underwater portion of the work consisted of: diver hand installation of concrete bags to repair large voids in the cyclopean wall, core drilling of 18" diameter holes through the toe, driven H pile, 13,620CY of dredging, 20,000SF of cellular concrete mats, forming and placing of 3,500CY of reinforced structural concrete all at the bay bottom, installation of steel sheet pile and 13,500CY of cementitious backfill. The topside work included a new concrete cap and new fender system all around the facility and other related incidental work.

17 change orders added $1,048,257 to the contract, yet the project finished over $1,000,000 under budget. The project also finished 6 months ahead of schedule.
