Lock and Dam 10, Island Building Project, Phase 3

The U.S. Army Corps of Engineers is issuing a Total Small Business Set‑Aside (FAR 19.5) solicitation (W912ES26BA009) for Phase 3 of the Lock and Dam 10 Island Building Project near Guttenberg, IA. The contract (NAICS 237990) requires the design and construction of multiple islands of varying sizes and shapes within the Mississippi River. Island bases will be formed with granular fill, supplemented as needed by main‑channel dredging, and topped with fine fill sourced from access and habitat dredging. Each island must be vegetated with native grasses and willows and stabilized using engineered rock structures, including groins, vanes, and stand‑alone rock features. Proposals are due by 13:00 ET on 9 April 2026. Technical requirements emphasize environmentally sensitive practices—use of native plant species and habitat‑derived fill—and robust rock stabilization methods. The point of contact for this opportunity is Justin Rose (justin.h.rose@usace.army.mil; 651‑290‑5422).
