Bell was awarded the prime HVAC contract to perform the phased replacement of the campus’s main air handling units located in mechanical spaces in multiple buildings. Bell worked closely with M/E Engineering and MCC’s facilities department to install site built custom AHU’s in extremely short durations. Air Handling Units, associated controls, piping and ductwork were demolished, installed new and commissioned within 4-6 week windows to allow for continuous operation of the existing heating and cooling system. Bell simultaneously completed upgrades to the science lab exhaust system, reheat coils and installed new perimeter finned tube radiation. Temporary chillers were provided to ensure maximum cooling ability during summer school sessions. The project was completed within a nearly impossible schedule with minimal system shutdowns or service interruptions to the campus.
