Attachment 3 - Compressor Detail.pdf

This document is a set of technical drawings and specifications (Amendment No. 0002) depicting mechanical, plumbing, and HVAC systems for a facility installation. The drawings include detailed schematics for compressed air systems, breathing air plant flow diagrams, water hammer arrestors, utility hose reels, emergency eyewash and shower stations, pipe penetrations through various structures, and equipment room layouts for compressor and chiller installations.

The specifications cover multiple system components and installation requirements including electronic trap primers with minimum 12-inch trap priming assembly connections, water service drops with hot/cold supply lines, horizontal branches not to exceed one sink length with individual shut-off valves, compressed air service drops with specified pressure ratings and gauge requirements, utility hose reels designed for 150 PSI working pressure with specific spring bearing and quick-disconnect specifications, and breathing air systems with designated equipment pads and automatic drain traps. Additional details address pipe sleeve requirements with sealant and insulation for floor penetrations, emergency shower and eyewash station mounting specifications with flow switches and pull chains, and isometric diagrams showing proper routing and coordination of compressed air distribution piping. The keyed notes reference Detail C1 on P-904 for compressed air piping diagrams and specify that all dashed equipment must be government-installed, with all other components provided by the contractor.
