About this file
This document is a mechanical engineering piping plan drawing for Building 65 at the Roseburg VA Medical Center, part of a campus-wide HVAC system replacement project. The detailed plan shows a first-floor piping layout with multiple technical specifications, including connections for chilled water and condenser water systems, new pump installations, and control panel replacements. Key technical details include:
Specific technical notes outline requirements such as connecting 8" and 10" carbon steel (CS) and chrome (CR) pipes, replacing chiller control panels with new Trane AdaptiView panels, installing a new 24" Onicon flow meter, and routing makeup water and drain lines. The plan includes modifications to existing cooling towers (CT-3, CT-4) and chillers, with provisions for heat tracing outdoor piping, revising piping drops to accommodate new larger pumps, and integrating new equipment with existing Johnson Controls (JCI) control systems. The project is for the Department of Veterans Affairs at the Roseburg, Oregon medical center, with the drawing prepared by IMEG Corporation and dated October 9, 2020.
