Contractors will oversee surface preparation, coating application and furnishing of coating materials. The steel will be abrasive blast-cleaned according to Near White standards (SSPC-SP 10 or NACE No. 2) with the blast-cleaned surfaces closely approximating Pictorial Standard SP 10 of SSPC-VIS 1, or cleaned to Very Thorough Waterjet standards (SSPC-SP WJ-2) with the appearance of the water-jetted surfaces to closely approximate Pictorial Standard WJ-2 of SSPC-VIS 4.
The steel will then be coated with a three-coat organic zinc system. The owner-approved manufacturers are Carboline, Sherwin-Williams and Wasser. A coating system warranty and supplemental warranty performance bond in the sum of $15,000,000 is required.
Contractors will oversee Solvent Cleaning (SSPC-SP 1) of aluminum surfaces followed by a light Brush-off Blast-Cleaning (SSPC-SP 16) and coating application. The project also includes water pipe surface preparation, inspection and coating. Fasteners will also receive Commercial Power Tool Cleaning (SSPC-SP 15), Solvent Cleaning (SSPC-SP 1) and coating of fasteners with a prime coating system.
Soluble salt testing and removal is required. Existing materials contain lead, chromium and cadmium. Containment and disposal of hazardous materials is also required.
