About this opportunity
The U.S. Army Corps of Engineers, Rock Island District, is seeking contractors for the Mississippi River Basin, Lock 19, Keokuk, IA, Nose Pier Replacement and Bulkhead Recesses project. The procurement includes a base bid for extending the riverwall monolith upstream with work encompassing mobilization, hydrographic surveys, concrete removal above and underwater, mechanical dredging, underwater rock excavation, monolith extension using precast concrete segments and tremie concrete placement, checkposts and other appurtenances, fabrication of protection plate assembly, and electrical work. Two additional options are included: Option 1 for constructing a bulkhead recess in the landwall and Option 2 for constructing the bulkhead sill with various specialized marine construction activities. The contract will be evaluated using the Lowest Priced Technically Acceptable criteria, ensuring contractors meet technical requirements while competing on price. The formal solicitation is anticipated to be issued on or around June 23, 2025, with the current pre-solicitation notice posted on May 6, 2025, and a due date of June 22, 2025.
This procurement is classified under NAICS code 237990 (Other Heavy and Civil Engineering Construction) with a size standard of $45,000,000 and is designated as unrestricted with no set-aside provisions. The contract magnitude is estimated to be between $25,000,000 and $100,000,000, reflecting the substantial scope of this marine infrastructure project. The work involves complex underwater construction activities, specialized concrete placement techniques, and coordination with existing lock and dam operations on the Mississippi River. For Option 2, bulkheads will be provided as government furnished equipment, reducing contractor procurement responsibilities for these critical components. The project represents a significant investment in maintaining and upgrading critical river navigation infrastructure at one of the Mississippi River's key lock and dam facilities.
