Lower Pool 2 Channel Improvement: Boulanger Bend to LD2 - Phase 1

The Lower Pool 2 Channel Improvement project, specifically Phase 1 from Boulanger Bend to Lock and Dam 2, involves the construction of two rock sills on the Mississippi River near Hastings, Minnesota. Managed by the Department of Defense through the US Army Corps of Engineers, St. Paul District, the work requires all plant, labor, and materials to build riprap structures with a top width of approximately 10 feet. One sill is located on the right descending bank from River Mile 819.5 to 819.8, and the other is on the left descending bank from River Mile 818.4 to 818.9. To ensure visibility, four-foot diameter boulders will be spaced along the top of the structures, and rock staging may occur on the downstream side of Lock and Dam 2. This contract, identified by solicitation number W912ES-17-B-0006, was issued as a 100 percent set-aside for small business concerns under NAICS code 237990. The estimated magnitude of construction is between 1,000,000 and 5,000,000 dollars. Technical specifications emphasize minimizing channel maintenance costs and include detailed geotechnical data and control points. The procurement process included updates to Davis-Bacon Act Wage Determinations for Dakota and Washington Counties and noted concurrent work on the Lock and Dam 2 Pavement Rehabilitation project.
