Specifications include, but are not limited to: 1. The project consists of the removal and replacement of the original HVAC systems within the repair garage, lunchroom, staff office area, staff locker rooms, and parts storage, as indicated on the mechanical bid documents. 2. The project HVAC system(s) will be brought up to current code requirements and improve system operations, performance, and user comfort while increasing energy efficiencies. 3. Demolition work shall include the removal of existing gas fired unit heaters, combination AHU’s / gas fired duct heaters, vehicle exhaust fans, electric air cleaners, ductwork, condensate piping, gas piping, roof mounted RTU’s and exhaust fans, abandoned hot water radiant floor heating system and associated piping and other equipment as shown on the mechanical bid documents. 4. The new mechanical equipment scope for the repair garage will consist of a roof mounted, high efficiency gas-fired make-up air unit with integral heat recovery and exhaust, variable speed drives, equalizer (destratification) fans, vehicle exhaust hose reels, infrared heaters, controls (by others), gas piping. The system will provide code required ventilation, while maintaining a 70°F space temperature at -10°F design conditions. 5. Lunchroom and staff offices will be served by a new variable volume heating and cooling rooftop unit with electric re-heat and supplemental electric baseboard heaters at window locations. In addition, this system will utilize an energy recovery ventilator for providing minimum code required ventilation and general exhaust.
