This document is a technical schematic and bill of materials for HVAC (Heating, Ventilation, and Air Conditioning) system modifications aboard the NOAA Ship Gordon Gunter. The drawing set includes multiple plan views, elevations, and sections detailing the installation of new mission space HVAC systems and modifications to existing systems.

The bill of materials (pages 5) specifies numerous components required for the installation, including fans, dampers, ducts, diffusers, terminal boxes, and various fittings and hardware. Components are sourced from manufacturers such as Spiral Metals Corp, Valco Electric, Hartwell Fan, and others, with materials including galvanized steel, stainless steel, and cast iron. The drawings indicate installation locations throughout the vessel's superstructure, with specific attention to the mission space, computer lab, wet lab, and general berthing areas. Key technical specifications include duct sizing (ranging from 4 inches to 27 inches in diameter), CFM (cubic feet per minute) requirements for various spaces, and detailed installation notes regarding clearances, structural support, and connections to existing systems. The work encompasses both supply and return air systems with provisions for natural supply ventilation, damper control, and coordination with existing mechanical systems already installed aboard the vessel.
