About this file
This solicitation is for a firm fixed price contract to provide maintenance dredging services for the Wilmington Harbor federal navigation channel reaches including the Anchorage Basin, Between Channel, and 32-foot Turning Basin, as well as berth areas and a Turning Basin Extension operated by the North Carolina State Ports Authority. The U.S. Army Corps of Engineers, Wilmington District requires hydraulic cutterhead dredging to depths of 32 feet plus 2 feet allowable overdepth for the 32-foot Turning Basin, 38 feet plus 2 feet allowable overdepth for the Anchorage Basin between station 0+00 to 40+00, and 42 feet plus 2 feet allowable overdepth for the Anchorage Basin between station 40+00 to 84+05 and for Between Channel. The NCSPA berth areas and Turning Basin Extension must be dredged to 39 feet plus 1 foot allowable overdepth and 43 feet plus 1 foot allowable overdepth, respectively. The estimated quantity of material to be dredged is 1.4 million cubic yards, to be disposed at the Eagle Island Cell No. 2 upland diked disposal area. This is a 100% small business set-aside, with a magnitude of construction between $5-10 million. The environmental window for NCSPA berths is October 1 to January 31, and August 1 to January 31 for federal channels. The solicitation will be issued on or around July 12, 2022.
