This is a Heating, Ventilation, and Air Conditioning (HVAC) Plan schematic drawing for the Enlisted Barracks Phase 2C Dining Facility project. The document is prepared by the U.S. Army Engineer District, Baltimore, Corps of Engineers, and is identified as drawing number F-721-90-12, sheet 1 of 3. The plan shows the detailed layout of HVAC systems and ductwork distribution throughout the dining facility, with multiple mechanical zones and equipment specifications indicated. The drawing includes a north arrow orientation and contains three notes regarding duct run specifications: 3⅜" duct run to 37.4" on roof, 8"x11" ceiling line to 32.4" with 90° elbows, and 8"x11" stainless steel duct to 37.6" on roof. The schematic uses a scale of ⅛" = 1'-0" and includes grid references (columns 1-5, rows A-D) for precise location identification of all HVAC components and distribution points throughout the facility.
