The City of Ann Arbor is seeking contractors to coat the South Industrial Tank, a 4-million-gallon ground storage tank located in Ann Arbor, Michigan.

South Industrial Tank
City of Ann Arbor

Ann Arbor, Michigan, is seeking bids for the cleaning and recoating of its South Industrial Tank, last recoated in 1996.

A pre-bid meeting will be held May 10, and attendance is highly recommended. 

Bids are due May 22.

Scope of Work

This project involves removing and reapplying coatings on the tank, which was last abrasive blast-cleaned and coated in 1996.

The project includes surface preparation to Near White (SSPC-SP 10) and painting of wet interior surfaces, including interior roof, sidewalls, ladder, piping and structural steel surfaces. Contractors will be required to apply a two-coat system with a zinc primer and epoxy topcoat to the roof down to the high water line.

Work also includes application of a three-coat epoxy system with a zinc primer to the sidewall and floor. The owner-approved coatings manufacturer is Tnemec.

Contractors will apply a two-coat epoxy system on pit piping.

External surfaces, including the roof, sidewalls, overflow pipe, and other appurtenances will require surface preparation to Commercial (SSPC-SP 6) before coating with a three-coat epoxy urethane system.

The project will also require dehumidification equipment and dust collectors. According to owner documents, the dust collectors should be equal in filtration capacity to those by Eagle Industries.

Why not specify an SSPC-SP-5 (yes, it's more expensive, but only marginally) and a better (dare I say, optimal) coating system, like a single coat 100% solids epoxy (which reduces application labor costs, somewhat offsetting SP-5)? What kind of guarantee comes with this work? What is the anticipated no-maintenance service life of the installed system? I just inspected two tanks I personally lined more than 20 years ago and the coating system is fine - no maintenance required. Would those involved with this project consider this coating system "optimal" or "suitable"?

Thanks Kevin. It's amazing to me that owners don't spend more time vetting in evaluating materials in an unbiased, vendor-neutral manner. The only thing left working on the owner's behalf after all the money is spent on blasting, logistics, spraying, scaffolding, disposal, bid-writing, etc., is the paint system. Yet it seems that in most cases, owner's defer to others to make a decision on material selection.
