About this file
This is a Solicitation document for a federal civil works contract issued by the U.S. Army Corps of Engineers, Kansas City District. The solicitation number is W912DQ26BA011 for the Missouri River Bank Stabilization and Navigation Project Contract C, specifically for Berger Bend navigation obstruction removal at river miles 90-91. The contract number is to be determined (TBD) with an issue date of March 2026. The project involves removal of navigation obstructions and bank stabilization work along a designated reach of the Missouri River near the Big Muddy National Fish and Wildlife Refuge in Missouri, between Omaha and Kansas City.
The contract documents include detailed civil engineering sheets depicting the project location, removal and disposal areas, typical structural sections for bank stabilization, and hydrographic data. Work involves removing material above specified cut elevations within defined removal areas and placing clean material in designated disposal areas in accordance with specification section 35 20 23 3.3.1. Removal is expected to exceed the approximate neat volume in order to remove all material above the cut elevation, with approximately 22,000 cubic yards for Berger Upstream and 10,000 cubic yards for Berger Downstream. Disposal areas include both upland locations over existing revetments and in-channel locations with specified minimum and maximum elevations. The project documents note that land access to removal and disposal areas is not available, and no tree clearing is permitted for placement of clean material in designated disposal areas.
