About this file
This is a mechanical roof HVAC plan drawing for a renovation project at a medical center facility in Mt. Home, Tennessee. The document depicts four floor plan phases showing the layout and installation of air handling units (AHUs), HVAC equipment, ductwork, and associated mechanical systems across multiple levels of the building.
The drawing notes specify several key mechanical requirements: installation of a metal cap on the roof curb to seal penetration (13.10); rebalancing of existing RTU to new design conditions (13.31); connection of new exhaust ductwork to existing roof ventilator (13.32); installation of a steam unit heater for the penthouse (13.33); connection of chilled water piping from a new chiller to the house system with a three-way valve (13.34); installation of a new thermostat to serve the steam unit heater and exhaust fan (13.35); and procurement and installation of a new AHU control panel with coordination for power and data connections (13.36). The design includes new roof-top air-cooled condensing units to serve AHUs 204-AHU-D and 204-AHU-E, and existing equipment modifications to serve new prep and recovery areas. The drawing is fully sprinklered and represents 100% bid documents prepared by FFE Engineering & Architecture as the architect/engineer of record.
