WPAFB Replace Cooled Water Lines Building 71D

Proposed project is to replace deteriorated steel process cooling water pipe system (facilities 71A, 71D, 20, and 20A) and served by cooling towers at facility 21624 (building 71D) with new steel and fiberglass reinforced pipe (FRP) piping. FRP piping shall be for direct bury applications and areas exposed to harsh environments, i.e. existing steam tunnels. Steel piping is preferred in all mechanical room spaces and where maintenance is easily accessed. Replacement of pumps, new Process Automation System controls which includes new control valves, new VFDs, process automation system programming, new Motor Control Center MCC-71D and associated Automatic Transfer Switch (ATS), conduit and miscellaneous control components. - Projects considered similar to this project include but are not limited to: mechanical room renovation or large chiller/HVAC replacement projects, to include demolition and removal of pumps, controls, and insulated carbon steel pipe (underground and tunnels). Projects similar in size to this project include: - Projects similar in size would consist of replacing mechanical equipment supporting multiple cooling towers with 2,000 to 3,250 tons cooling capacity and 3,000 to 4,800 GPM of condenser water flow.
