The contractor shall also be responsible for taking possession of Owner supplied heat exchangers, control devices, control valves, energy meters, control panels, and primary side isolation valves for installation and commissioning.

.2 In addition to supplying the equipment listed in the specification, the

contractor will supply required quantities of carbon steel pipe, stainless steel tubing, copper pipe, elbows, tees, reducers, unions, flanges, insulation, thermal blankets, couplers, isolation valves, strainers, and suspension devices for all of the heating and domestic hot water energy transfer stations.
