Attachment C Water Tank Specifications 2.pdf

This is an as-built architectural drawing for a 500,000-gallon prestressed concrete reservoir located in Ray Pines, Florida. The drawing details the structural design and construction specifications for a water storage facility developed by the Department of Veterans Affairs.

The reservoir features a prestressed composite wall construction with a steel shell and shotcrete interior, utilizing a dome roof with 3-inch thickness at 40 degrees from the wall. The structure incorporates wire bar supports, circumferential bars, and diaphragm elements throughout. Key structural specifications include a 26-gauge steel shell diaphragm, #3 and #4 wire fabric reinforcement, and 4x4 welded wire fabric on 1.5-inch spacing. The dome design uses 1/2-SB-1 wire bar supports with field bend exterior vertical resteel and minimum 2-inch concrete cover. The floor utilizes a 4-inch concrete base with #4 rebar spacing at 4 inches on center and includes a soft broom finish for both interior and exterior surfaces. Notable construction details include access hatches with fiberglass covers, a prestressing schedule indicating wire tension measurements, and horizontal wall sections showing core wall dimensions of 3.5 inches at the base with circumferential bar reinforcement.
