About this opportunity
The U.S. Army Corps of Engineers Rock Island District is soliciting bids for a complex marine infrastructure project involving nose pier replacement and bulkhead recess construction at Lock 19 on the Mississippi River in Keokuk, Iowa. The procurement includes a base bid for extending the river wall monolith upstream, which encompasses mobilization, hydrographic surveys, concrete removal above and underwater, mechanical dredging, underwater rock excavation, monolith extension using precast concrete segments, and electrical work. Additionally, the contract offers two options: Option 1 for constructing a bulkhead recess in the land wall with cofferbox fabrication and installation, and Option 2 for constructing a bulkhead sill with drilled shafts and stay-in-place formwork. The project will be evaluated using Lowest Price Technically Acceptable (LPTA) criteria under NAICS code 237990 with a size standard of $45 million. The solicitation was posted on June 18, 2025, with proposals due by August 11, 2025, and questions must be submitted through Projnet.
This procurement is unrestricted with no set-aside designations, making it open to all qualified contractors regardless of size or socioeconomic status. The estimated contract value ranges from $25 million to $100 million, representing a significant investment in critical river infrastructure. The base contract requires completion within 638 consecutive calendar days, which extends to 973 consecutive calendar days if Option 2 is awarded by the government. Performance will take place at Lock 19 in Keokuk, Iowa, along the Mississippi River, requiring specialized marine construction capabilities and experience with underwater operations. The government has issued multiple amendments to the solicitation, including updates to specifications, plans, wage determinations, and the addition of requirements for payments to small business subcontractors, demonstrating the project's complexity and the agency's commitment to refining contract terms.
