MO Ground Storage Tank Out for Bid
Springfield City Utilities is seeking contractors for the rehabilitation of the Blackman Wash Water Storage Tank in Springfield, Missouri.
Bids are due May 3; a non-mandatory pre-bid meeting will be held April 23.
Scope of Work
This project involves cleaning and coating the interior and exterior surfaces of an existing 300,000-gallon ground water storage tank.
Contractors will high-pressure waterblast (3,000-5,000 psi) and power-tool clean exterior tank surfaces to SSPC-SP 3 standards. The exterior will then be spot primed with a modified polyamidoamine epoxy and coated with an acrylic-polyurethane topcoat.
An alternative bid item includes priming the exterior surfaces with an epoxy/polyurethane primer/intermediate system and coating with a fluoropolymer topcoat.
Interior tank surfaces will be abrasive blast-cleaned to Near White standards (SSPC-SP 10). The interior surfaces will then be coated with a zinc-rich urethane primer and epoxy finish.
The approved coating manufacturer is Tnemec. Seams will be sealed with Sikaflex-1a.
Containment of abrasive-blast debris is required.
Springfield City Utilities will supply a third-party inspection firm to perform full-time observation of the repair work, cleaning and painting.
A second-year anniversary inspection shall be performed by the contractor.
