This is a mechanical engineering specification sheet for HVAC renovation work at CFMO Building 1707 in Charleston, West Virginia, prepared by The Thrasher Group, Inc. for the West Virginia Army National Guard. The document provides detailed technical specifications for a complete HVAC system installation including symbol legends, abbreviations, general mechanical notes, demolition procedures, and equipment schedules. The project scope encompasses the installation of three rooftop units (RTU-1, RTU-2, and RTU-3), 27 variable air volume (VAV) terminal units with electric reheat coils, seven electric unit heaters (EUH-1 through EUH-7), and various ductwork, diffusers, grilles, and control components. The specifications detail specific manufacturer requirements (primarily Titus and AAON equipment), electrical connections (208/3 and 480/24 volt systems), and CFM (cubic feet per minute) requirements for each unit, with cooling capacities ranging from 620 to 5,685 CFM and heating loads specified for individual zones.

The document establishes comprehensive technical and operational requirements for contractors, including mandatory coordination with other trades, protection of existing equipment to be reused, proper cabling and grounding standards, and compliance with the International Fuel Code 2018 for gas sizing calculations. All ductwork is specified as Schedule 40 metallic pipe with internal clear dimensions, flexible connections at vibration-prone connections, and 1-inch ductliner in return air ducts. The project references 1981 and 2026 bid documents, with contractors required to verify existing conditions prior to bidding and adjust installation at no additional cost to the owner. The electrical connections range from 208/3 phase for VAV units and individual heaters to 480/24 volt transformers, with the total gas load specified at 660 MBH across the three rooftop units. The specification sheet was dated June 26, 2026, with Addendum No. 1 issued on July 15, 2025.
