The contractor is required to transport, inspect, and rehabilitate twelve (12) draft tube bulkheads and associated seal keeper bars. Each top bulkhead weighs approximately 29,000 pounds (valued at $850,000) with dimensions of 9 ft 7 in tall x 27 ft 7 in wide x 3 ft thick; each bottom bulkhead weighs approximately 26,500 pounds (also valued at $850,000) with dimensions of 9 ft 6 in tall x 27 ft 7 in wide x 3 ft thick. The rehabilitation work includes existing coating removal via dry-blasting to white metal per SSPC SP 5/NACE No. 1 with angular profile of 1.5-2.5 mils, 100% weld inspection using Visual Testing (VT) and Magnetic Particle Testing (MT) methods per AWS D1.1, weld repairs not to exceed 40 linear feet using 70KSI electrode, and new coating application using USACE coating system 5-E-Z (vinyl-type zinc-rich primer plus vinyl topcoats) to a minimum 7.0 mils dry film thickness. The contractor must provide a certified SSPC QP 3 painting contractor or AISC Complex Coatings endorsed personnel, qualified welders and inspectors per AWS standards, and a third-party certified coatings inspector (SSPC-PCI Level 2 or NACE CIP Level 2).
