Document Summary

This is a set of mechanical design and engineering drawings for the Electronic Security Command Complex at Utah Air National Guard Base, Salt Lake City, Utah. The drawings detail HVAC system modifications for Building 302, specifically the heating, cooling, and mechanical piping infrastructure. The project, titled "Building 302 - HVAC Update," was prepared by FFKR Architects and is dated August 19, 1991, with record drawing revisions current as of that date.

The drawings provide comprehensive technical specifications for mechanical systems including air handling units, diffuser schedules, VAV box configurations, fan-powered VAV boxes, radiant heating panels, pump systems, and detailed piping schematics for chilled water, heating water, and refrigerant lines. Mechanical equipment schedules specify equipment types, sizes, model numbers, and performance specifications for multiple HVAC components. The drawings include installation details for ductwork, fan coil units, expansion tanks, chemical feeders, and various seismic restraint connections to concrete and steel. Low-pressure duct details, ceiling diffuser installation guidance, radiant panel zone piping schematics, and sub-zone system schematics are provided to support construction implementation. Cable restraint details, equipment mounting specifications with and without vibration isolation, and general bracing pipe guidance complete the technical documentation package for this mechanical systems upgrade project.
