In all, Kaempf & Harris Sheet Metal utilized 600,000 pounds of galvanized ductwork to construct a commercial-grade HVAC system for the 270,000-square-foot Frederick High School in Frederick, Maryland. Included is 16,000 pounds of solid welded stainless steel to serve 25 air handler units, 67 fans, five make-up air units and 113 heat pumps. Also, Kaempf & Harris installed six mechanical rooms, 1,500 registers, grilles and diffusers, and 305 fire and fire/smoke dampers, which enabled the building to meet LEED Silver standards for environmentally friendly operations.

The project was completed a little more than two years ago. Manpower peaked at 20 people, Kaempf & Harris president Aaron E. Smith says, which allowed the newly built school ample time to test the system before opening. Oak Contracting served as the general contracting partner on the project.
