About this file
This document is a mechanical engineering design drawing (Sheet M-301) for a cooling water system renovation project at Cherry Point, detailing a phased demolition and replacement plan. The project involves two primary phases: Phase 1 includes removing water-cooled childers, cooling towers, and associated condenser water piping, and installing a buffer tank with temporary chiller connections to maintain building operations. Phase 2 consists of removing Phase 1 caps, providing equipment connections to tees, tying in chiller supply piping to the main, and updating controls. The design specifically shows demolition sections and new work sections at Level 1, with detailed piping configuration, valve placements, and system modifications. The drawing is marked unclassified and features logos from NAVFAC and Mason-Hanger, suggesting this is a federal facility infrastructure upgrade project requiring precise mechanical system reconfiguration.
