About this file
This document is a naval facilities engineering drawing (MP111) for a chiller replacement project at Marine Corps Air Station Cherry Point in North Carolina. The project involves a phased demolition and replacement of water-cooled chillers, cooling towers, and associated condenser water piping. Phase 1 specifically focuses on removing existing water-cooled chillers, cooling towers, and installing a new buffer tank while maintaining building operations through temporary chiller connections. Key details include patching roof penetrations, removing pumps and associated equipment, disposing of refrigerant and compressor oil according to RCRA procedures, and retaining existing control boxes for future use. The project is being executed by NAVFAC SYSCOM Mid-Atlantic, with the drawing dated March 22, 2024 and a revision noted for 8/26/25. The technical drawings provide detailed piping plans for both demolition and new work at Level 1, showing the precise layout of existing and proposed mechanical systems.
