This is a mechanical plan drawing for a US Naval Research facility. The document is marked "FOR OFFICIAL USE ONLY - DISSEMINATION FOR SOURCE SELECTION PURPOSES" and shows a detailed floor plan layout with HVAC, plumbing, and building systems specifications.

The drawing depicts a multi-story building section with mechanical systems including chilled water lines, hot water piping, thermostats, pressure gauges, expansion tanks, and related HVAC equipment. General notes specify that information is based on existing conditions obtained from available building records and field observations, with the contractor responsible for verifying actual existing conditions and determining final routing. Special notes identify 19 specific installation locations and requirements throughout the building, including placement of chiller units on the west side, installation of vibration hose on supply and return lines, thermostats on both lines, pressure gauges, pipe supports using unistrut with custom clamps, bulkier drains, butter tank specifications, expansion tank locations, air bleeders placement, converter pad location, chilled water supply lines, chilled water return lines, manifold locations, furnace equipment positioning, and connection points for expansion. The plan references drawing M-101 and is not to scale, indicating this is supplementary documentation for a construction or renovation project at a US Naval Research facility.
