About this file
This document is an HVAC ductwork and equipment plan for Level 2 North of a building facility. The plan provides detailed schematic layouts of the heating, ventilation, and air conditioning distribution system at a scale of 1/8" = 1'-0".
The plan depicts numerous ductwork runs with specific dimensions (ranging from 6" to 32" in various rectangular and circular configurations), multiple VAV (Variable Air Volume) boxes with airflow specifications (ranging from 140 CFM to 490 CFM), rooftop units (RTU-21 through RTU-27), exhaust fans (EF-01 through EF-10), and associated HVAC equipment. Key equipment labeled includes supply grilles (SG designations with airflow ratings), return grilles (RG), exhaust grilles (EG), thermostatic controls, dampers, and interconnecting ductwork. The plan also identifies gravity dampers (ZD-1 through ZD-9), terminal units (TG-1 and TG-2), and various duct fittings. A critical note indicates that the ductwork and equipment shown are from record drawings and have not been field-verified. Drawing notes reference specifications M-121 and M-122 for additional HVAC unit and control details.
