Dworshak Skeleton Bay Draft Tube Bulkhead Rehabilitation

The U.S. Army Corps of Engineers seeks a contractor to rehabilitate twelve draft‑tube bulkheads at the Dworshak Dam (Idaho). Work includes transporting the bulkheads to a repair facility, dry‑blast cleaning, weld inspection and repair (up to 40 ft per bulkhead), application of a specified coating system, and returning the refurbished units to the dam. The effort is phased over three periods, with tight delivery windows in late 2026 through mid‑2027, and requires extensive documentation, security clearances, and an on‑site warranty. • Transport 12 bulkheads (6 top, 6 bottom) to/from repair facility, with approved handling and transportation plans. • Perform blasting, 100 % weld inspection (VT/MT), limited weld repairs, and apply USACE coating system (minimum 7 mil dry‑film). • Provide detailed inspection reports, adhere to strict scheduling (phase‑1 by 21 Jan 2027, phase‑3 by 1 Jul 2027), and furnish a one‑year warranty on coating and workmanship.
