Solicitation # W912WJ27X1CUP
The U.S. Army Corps of Engineers, New England District, is seeking information from small and large businesses for a dredging project in Providence, Rhode Island, under NAICS code 237990. The project is estimated to cost between $80,000,000 and $100,000,000, with a solicitation expected around March 15, 2027. Construction is scheduled to begin in September 2027 and last approximately two years, spanning two dredging seasons from September 1, 2027, to August 31, 2029. The work is divided into two primary sequences: the construction of a new Confined Aquatic Disposal (CAD) cell at Edgewood Shoals North, including an access channel, and the subsequent maintenance dredging of the Providence River and Harbor Federal Navigation Project to a depth of -40 feet MLLW plus two feet of allowable overdepth. The total scope involves mechanically dredging approximately 5,500,000 cubic yards of material using closed clamshell buckets. Specifically, 3,200,000 cubic yards will be removed to create the CAD cell, with material placed at Port Edgewood Basin, Fox Point Reach CAD cells, Prudence Island, and the Rhode Island Sound Disposal Site. The remaining 2,300,000 cubic yards of maintenance material will be placed within the newly constructed Edgewood Shoals North CAD cell. To meet strict environmental windows and project timelines, the contractor must maintain a production rate of at least 300,000 cubic yards every 30 calendar days, operating 24 hours a day, 7 days a week. Interested firms must submit a capabilities package by November 26, 2026, demonstrating experience with these production rates and open water placement in New England during winter months.
