Construction Services for Confined Aquatic Disposal Cell Construction and Maintenance Dredging of the Providence River Federal Navigation Project, Providence, Rhode Island.
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 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. Capabilities packages are due by December 3, 2026.

The U.S. Army Corps of Engineers, St. Louis District, is soliciting bids for the construction of lock foundation and site preparation work at Lock and Dam No. 25 under solicitation W912P926RA001, with a response deadline of April 24, 2026. The work includes excavation and disposal of existing riprap, dredging and placement of sand fill for the lock foundation, installation of a sheet pile separator wall braced with piles, construction of a downstream deflector to redirect water flow, and placement of additional dredge borrow for a staging area along with a sanitary outfall pipe. The contract requires the contractor to furnish all equipment, labor, operators, supervision, materials, and incidentals necessary to complete the scope, with performance to be conducted at Winfield, Missouri. The solicitation explicitly prohibits paper submissions and mandates that proposals be submitted electronically via email to Angie Grimes and Whitney Dee, with strict requirements for three separate PDF volumes: technical proposal, small business participation, and price proposal with administrative documents. Each volume has strict page limits, cross-referencing between volumes is forbidden, and proposals exceeding limits will be partially evaluated. Contract type is firm fixed price, and award will be made on a best value trade-off basis, with construction approach and past performance equally weighted and more critical than small business participation, all of which are balanced against price. The solicitation has undergone multiple amendments to refine requirements and ensure compliance. Amendment 0005 replaced the standard FAR clause 52.236-16 with Alternate 1 and incorporated updated drawing sheets GI002 and CG203, while Amendment 0006 introduced tax exemption language. Earlier amendments addressed bidder inquiries via the ProjNet portal, with inquiries reopening through April 3, 2026, and administrative updates made through Amendment 0002 and 0001. The evaluation process is governed by four factors—construction approach, past performance, small business participation, and price—with no numerical weights but clear qualitative thresholds; offerors must achieve at least a marginal rating on all non-cost factors to be eligible for award. Proposal submissions must comply with SAM.gov registration, including a valid UEI, and require certifications regarding small business status, subcontracting plans, E-Verify compliance, and security training. Security requirements mandate DoD/Army training within 30 days of award, compliance with FPCONs and RAMs, NCIC-II

The U. S. Army Corps of Engineers, St. Louis District, is seeking a firm to furnishing all equipment, labor, operators, supervision/site superintendent, quality control, supplies, materials, and incidentals necessary to satisfactorily perform and provide construction activities of lock foundation and site preparation work.  The lock foundation work establishes the lock wall and floor foundation. It consists of excavation and disposal of existing scour protection riprap that was part of previous scour hole emergency repair, dredging of sand fill, placement of sand fill in the proposed lock foundation, and placement of riprap berm. Work also includes the construction of a separator wall that will separate the river side riprap berm from the dredged sand that will be placed as foundation material for the future river wall monoliths and lock floor. The separate wall will be a sheet pile wall braced with piles. This effort also includes a deflector on the downstream side of the dam to route water flowing through the tainter gated dam adjacent to the river walls around the sheet pile separator wall.   For the site preparation work, additional dredge borrow will be placed upland for a future staging and laydown area and a sanitary outfall pipe will be installed.
