The project consisted of the replacement of existing Air Handling Units 12 & 13 at Grady Memorial Hospital. The existing units are in the basement mechanical room. Thanks to increasing equipment in the areas served, both replacement units have 20% more capacity than the original units. AHU-12 is an approximately 15,500 CFM constant volume unit and AHU-13 is a 20,000 CFM variable volume unit. The ductwork in the mechanical room needed to be revised to accommodate the unit replacement and downtime minimized to avoid facility disruption.
