This is a mechanical piping plan drawing for a steam boiler replacement project at the Northern Arizona VA Health Care System located at 500 N. State Highway 89, Prescott, Arizona 86313. The drawing is part of the formal construction documentation for Project Number 649-22-104, issued by the Office of Construction and Facilities Management under the U.S. Department of Veterans Affairs.
The mechanical plan details the installation of new steam and boiler feed water piping systems throughout the facility, with key requirements including: phased installation to minimize downtime with new work completed prior to demolition; scheduling of shutdowns and facility switchover with approval required 21 days in advance; fire-rated caulking of all pipe penetrations through exterior walls, roofing, and mechanical room walls; replacement of existing pipe hangers where piping is being replaced; X-ray verification of all new steam and boiler feed water welds; installation of a new deaerator tank in the same location as the existing unit with safety overflow; modification of existing catwalks for boiler access; replacement of high-pressure and installation of low-pressure steam piping throughout the plant to the existing tunnel; installation of new exhaust fans on the roof; installation of outdoor unit OU-1 with an 18-inch housekeeping pad; and extension of the exhaust flue servicing the generator room from the existing duct through the roof. The drawing scale is 1/4" = 1'-0", was approved on January 29, 2026, and includes Addendum #2 dated June 29, 2026, with the document set to expire on June 30, 2027.
