The contract covers maintenance dredging operations from river miles 183.3 to 857.6 across three USACE districts (St. Louis, Rock Island, and St. Paul), including mechanical dredging of navigation channels and small boat harbors, transportation of dredged material up to 12 river miles, and placement of material in upland, bankline, or thalweg sites. Key requirements include the capability to remove at least 2,000 cubic yards per day or 10,000 cubic yards per week, and the contract utilizes firm fixed pricing with unit prices for various dredging and transportation activities. The solicitation was an unrestricted invitation for bid requiring electronic submission via email along with a 20% bid bond. Bids were due on October 14, 2025, at 10:00 AM Central Time, and the bid opening occurred on that same date.
This procurement does not utilize any set-aside designations and received proposals from two bidders: Dubuque Barge & Fleeting Service Company and Legacy Corporation of IL. The total estimated contract value ranges from $10-25 million, with the government estimate at $13,606,020.10, while the two bidders submitted proposals of $11,593,090.20 and $17,281,725.20 respectively.
