About this opportunity
The Department of the Army Corps of Engineers, Detroit District, is soliciting bids for mechanical dredging services in the Duluth-Superior Harbor channel through a Full-and-Open Competition Invitation for Bid. The primary scope of work requires contractors to mobilize dredging equipment and perform mechanical dredging across four designated dredge areas: Duluth Anchorage Area (Area 3), East Gate Basin (Area 6), Superior Front Channel near Barkers Island (Area 11), and Superior Entry between pier and breakwater structures (Area 17). The contract includes optional work for additional dredging in Areas 3 and 14 near the Nemadji River mouth. Critical contract requirements include mechanically placing dredged material at the Erie Pier Confined Disposal Facility with material washing operations to segregate fine to coarse-grained sands from silty material, stockpiling washed sand on-site, and conducting sieve analyses for every 10,000 cubic yards of washed sand to verify proper separation of fines. The bid opening occurred on March 11, 2026, which was the extended due date following Amendment 0001, with Amendment 0002 modifying FAR 52.217-7 provisions prior to bid submission.
This solicitation is not designated as a set-aside. Three contractors submitted bids by the March 11, 2026 deadline: Dean Marine and Excavating, Inc., Roen Salvage Co., and Morrish-Wallace Construction, Inc. d/b/a Ryba, with all three providing 20% bid security. The government estimate for the base contract is $4,277,649.00, while the submitted bids for total base and all options ranged from $3,993,900.00 (Roen Salvage Co., the apparent low bidder) to $6,563,003.00 (Dean Marine and Excavating, Inc.), with Morrish-Wallace Construction bidding $5,515,144.00. The work will be performed in Superior, Wisconsin, and encompasses mobilization, demobilization, and tiered cubic yard pricing for dredging quantities that exceed initial thresholds across multiple dredge areas. Contractors must complete all dredging and material placement operations before final demobilization.

The contract also includes options to perform additional dredging within Dredge Area 3 at the Duluth Anchorage Area and Dredge Area 14 near the mouth of the Nemadji River. Dredged material will be mechanically placed at the Erie Pier Confined Disposal Facility (CDF). Placement at this facility will require material to be washed to segregate fine to coarse grained sands from silty poorly draining material. The sand will have to be stockpiled on site. Every 10,000 CY of washed sand will require a sieve analysis to confirm the washing operations is sufficiently separating the fines from the sand. The Contractor would then demobilize when dredging and material placement are complete.
