========================================

I've gotten several estimates (all over $30K), and a large enough
survey adjustment to make for a satisfactory deal.

Have you had any tanks made from 1/4 or 5/16 aluminum? I'm
particularly looking for fabrication advice regarding coatings,
geometry, baffles, fill/vent/drain fittings, etc.

The tanks will be made by a contractor but I want to be sure they are
spec'd properly.

I'd hire a naval architect for a day. Stuff like designing a 500 gallon
tank probably should not be left to a contractor.

Baffles will be absolutely required, about every 24-30", External
stiffeners will probably be required, depending on the head on the tank
(height from bottom of tank to top of the vent). Geometry - will you
duplicate the existing tanks?

The existing tanks are hard to see until taken out.

Agree strongly! While I hesitate to suggest that it *must* be an
adversarial relationship, you really don't want the low-bid contractor
doing both the design and construction. If you're going to drop that
much money, you should spend the small amount extra to get a proper
design for the tanks.

Also I am slightly surprised that nobody suggested Monel... if it's
going to cost that much anyway...
