Summary: The original scope of services was for design, construction administration and commissioning of a new Very High Efficiency (VHE), all-electric heating and cooling (HVAC) system at the Forest Preserves’ General Headquarters. Additional services are needed for the continuation of commissioning required by a ComEd grant for the VHE HVAC system following an unforeseen installation problem. Piping was installed incorrectly between equipment units that had already been tested and commissioned, requiring re-installation and recommissioning. As the Engineer of Record for the new HVAC system, Interface Engineering is uniquely qualified to provide the additional services in a timely, correct and complete manner.
