This HVAC renovation project at a historic 100-year-old elementary school involved installing 13 rooftop units, Bard wall-hung AC units, and upgraded HVAC controls. The scope also included exhaust fans, structural steel, roofing repairs, and wall restoration to match the original stucco. Challenges such as limited laydown space, tight scheduling, and unforeseen conditions due to the building’s age were overcome with creative solutions like disassembling air handling units for access and coordinating with external commissioning agents. The project was completed on time, under budget, and delivered $100,000 in savings.
