Summary
The structure is a 1,000,000 gallon composite elevated water storage tank with a high-water level of 172' 8". The work includes: exterior: high-pressure water clean (5,000 to 10,000 psi) and spot power tool clean to an sspc-sp11 standard. There are several panels that have extensive coating failures on the roof that will need to be water dampen abrasive blast cleaned to a sspc-sp6 standard. Apply a three (3) coat epoxy urethane fluoropolymer system. Wet interior: spot power tool clean the spot coating failures on the roof, roof stiffeners, and roof painter's railings to an sspc-sp11 standard. Apply a spot two (2) coat epoxy system to the prepared surfaces. Dry interior: abrasive blast clean the spot coating failures throughout to an sspc-sp6 commercial standard. Apply a spot two (2) coat epoxy system to the prepared surfaces. Repairs: install a gasket on the wet interior roof hatch outside the handrail. Install handholds at the roof hatches inside the handrail. Overflow discharge modification. Replace the fall prevention device on the wet interior ladder. Install a ladder extension above the top platform. Install roof rigging couplings.
