The U.S. Army Corps of Engineers, Rock Island District, is seeking hydraulic dredging services to maintain navigable channels on the Illinois Waterway from River Mile 0.0 to 291.0. This Indefinite Delivery/Indefinite Quantity (IDIQ) contract will address continuous sediment deposition that creates navigation hazards and reduces channel depths, supporting commercial traffic, flood risk management, and waterway reliability. Offerors must demonstrate the capability to perform hydraulic dredging at a minimum production rate of 4,000 cubic yards per day or 20,000 cubic yards per week and submit proposals with documentation of relevant past dredging contracts from the last seven years, details of available hydraulic dredging equipment, and completed Past Performance Questionnaires. The government will evaluate proposals using a Lowest Price Technically Acceptable (LPTA) source selection process, with three evaluation factors: Price, Past Performance, and Plant and Equipment; offerors must receive an "Acceptable" rating in non-price factors to be considered. Proposals must be submitted electronically by January 22, 2026, with strict formatting and page limit requirements specified in the solicitation documents.

This contract is designated as a Total Small Business set-aside, restricting competition to small business firms. The IDIQ contract will cover five ordering periods from February 2026 through December 2030, with an estimated dredging quantity of 125,000 cubic yards for the first increment and 50,000 cubic yards for subsequent increments per ordering period, with a total contract maximum of $25,000,000 and a minimum order requirement of $50,000. The dredging work will utilize hydraulic cutterhead dredges with a minimum 16-inch and maximum 18-inch discharge diameter and will include comprehensive requirements for equipment management, environmental controls, safety procedures, and quality control. The place of performance is Peoria, Illinois, and the contractor must manage dredged material placement at designated sites while maintaining navigation channel depths and removing sediment accumulations along the waterway corridor. The Rock Island District will issue task orders specifying exact dredging locations and quantities as part of this multi-year maintenance dredging program.
