Frost and Keeling participated in the Design, and Renovation of the approximately 452,000 square foot LEED silver certified headquarters for multiple Air Force Agencies, including AFCEC, converting a quarter-mile-long building from an office and storage facility into a headquarters building. Our scope of work included the turn-key installation of all Mechanical, Plumbing, and Building Automation & Control Systems. The work included demolition of existing cooling towers and associated equipment from the roof of the facility and the installation of new 400 ton cooling towers, condenser water pumps, and modification of existing piping to match the configuration and application of the new HVAC equipment. Cooling within the building was provided by twenty-two single-zone and six multi-zone air handling units fed by the chilled water system. The chilled water system included two primary chilled water pumps and three secondary chilled water pumps. Heating to the facility was provided by three hot water boilers and associated hot water pumps. Our team also performed a turn-key installation and integration of the Johnson Controls DDC Building Automation Control System for complete control/management of the HVAC, lighting controls, and fire alarm systems monitored on the base-wide EMCS systems. In addition to the Mechanical installation, Frost & Keeling performed the turn-key plumbing installation which included domestic hot and cold water piping, low flow plumbing fixtures, and waste/vent/drain to the sanitary sewer system.
