Bolted Water Storage Tank Installation

Bolted Water Storage Tank Installation

This project was performed for Bostik Corporation in Middleton, Ma. They required a fire protection storage tank that would supply water for three buildings on site. A pump station will be installed to pressurize 8” concrete lined steel piping. This NFPA-22 single wall insulated fire protection aboveground storage tank (AST) was designed and installed to store clear water.

The concrete ring foundation is about 23-24" in width all the way around instead of the recommended 18". This allowed us to have a little room to accommodate any error in the foundation as we hand built and placed the forms. The original reveal was intended to be 12" from the outside edge of the concrete ring foundation to the tank shell wall. The tank shell wall is nearly directly centered in the middle of the tank ring foundation.

These measurements reflect the tank placement at a more aesthetic location centered on the foundation ring. This places the final 180° resting place for the tank @ 4-5" to the right (East) of the final markings that we were provided to align the tank to coordinate with the pump house and piping.

The structural engineer assured us that the tank foundation is structurally sound and really only needed a 4.5" reveal according to the standard that the tank was designed.
