Amphitheater HVAC Replacement, Arlington National Cemetery, VA
This project was for the removal and replacement of the existing roof top units, RTU's 1 and 2. These units were removed (to include all control dampers and associated actuators and any other control devices/sensors located within the unit) and replaced as indicted. The existing roof curb and roof penetrations were used to the maximum extent possible. New roof penetrations were sealed to match existing. The existing RTU was removed from the roof before placing new ones. The roof top replacement required use of a crane, which required a crane plan prior to submittal for government approval. Both RTU's were placed in a single day. There was the requirement that the building not be without cooling for a maximum of two days.
