About this file
This is a mechanical engineering drawing for a basement piping plan related to steam boiler replacement at the Northern Arizona VA Health Care System facility located in Prescott, Arizona. The drawing, designated as Sheet MP100, was issued on 08 APR 2026 and is part of Project Number 649-22-104, Building 111, with Addendum #2 dated 06/29/2026.
The drawing specifies comprehensive mechanical work requirements for the replacement of existing steam boilers and associated piping infrastructure. Key contractual requirements include: phasing new work with demolition to minimize facility downtime, with new installations completed prior to final demolition; scheduling facility shutdowns and switchover with 21-day advance approval; sealing all pipe penetrations through exterior walls, roofing, and mechanical room walls with fire-rated caulk; modifying existing boiler piping support systems; replacing all existing pipe hangers where pipe is being replaced; verifying all new steam and boiler feed water piping with X-ray inspection to ensure proper weld sealing; replacing existing sump pumps while retaining the existing waste pump; installing a new pressure relief valve (PRV) station in phases (1/3 valve first, followed by 2/3 valve after operational verification); and submitting plans for approval to reduce downtime. The drawing includes detailed piping configurations with various pipe diameters (2" to 8"), material designations (HPS, LPS, DCW, CT, SW), and shows connections to the drainage system. The document is sealed by Kevin M. Kosor, a registered Professional Engineer in Mechanical Engineering (Certificate No. 44759), with certification valid through 06/30/2027.
