Appendix_4_-_245-713-2122_22X34_(1).pdf

This document is a technical piping diagram for a chiller system designed for the Eastern Colorado Area Office facility. The diagram illustrates the complete chilled water system configuration, including the main chiller unit positioned centrally, with supply and return lines distributing conditioned water throughout the building. Key system components include isolation valves at strategic points, a flow meter for monitoring water circulation, check valves to prevent backflow, and shutoff/isolation block valves for maintenance purposes. The diagram shows temperature control devices, an expansion tank (ANT OVFL) for managing system pressure, and condensate drain lines. The system incorporates both hot water supply lines and chilled water distribution with separate return paths, along with auxiliary cooling equipment and water treatment components. The drawing references document number 245-713-2122 and includes the agency seal with the motto "ALWAYS THINK SAFETY." This appears to be a design or as-built documentation diagram rather than a solicitation document, providing technical specifications and spatial layout for the facility's mechanical systems infrastructure.
