Removal and replacement of (36) rooftop HVAC units.  Scope included new electrical feeds, ductwork and registers, controls, and fire alarm.

Work was performed at night and on weekends to prevent disruption to ongoing building operations.

Due to the critical nature of the facility operations, all electrical tie-ins were performed on live circuits, thus preventing shutdown of production equipment.  FAA crane height restrictions required the fabrication of plywood ramps to roll HVAC units across existing roof to their actual locations.
