The project is estimated to cost between 80 million and 100 million dollars, with a solicitation expected around March 15, 2027. Construction is slated to begin in September 2027 and span approximately two years, divided into two dredging seasons ending August 31, 2029. The scope involves the mechanical dredging of approximately 5.5 million cubic yards of material using closed clamshell buckets. The work is divided into two primary sequences. First, the contractor must construct a new Confined Aquatic Disposal (CAD) cell at Edgewood Shoals North, which includes digging an access channel and excavating 3.2 million cubic yards of material for disposal at four designated sites. Second, the contractor will perform maintenance dredging of the Providence River and Harbor Federal Navigation Project to a depth of -40 feet MLLW plus two feet of allowable overdepth, removing approximately 2.3 million cubic yards of material to be placed in the newly constructed CAD cell. Strict operational requirements include maintaining a production rate of 300,000 cubic yards every 30 calendar days, working 24 hours a day, 7 days a week. All activities must adhere to prescribed environmental windows to protect aquatic wildlife, and extensions to these windows are not permitted. Interested firms must demonstrate experience with mechanical dredging at the required production rate and open water placement in New England during winter months.
