a. Design, build, and install new mini-split heat-pump systems (optimal cooling;

low-ambient heating) for Buildings 1 and 2 containing the women’s and men’s restrooms, jockey dressing rooms, and two-story office area. Prepare drafted shop drawings and ACCA Manual J calculations detailing the HVAC designs under the supervision of a Maryland licensed Professional Engineer.

1) New HVAC systems shall be complete installations to include all duct work; air handlers; compressors; electric whips; refrigerant lines;

refrigerant line insulation; refrigerant line covers; condensate drains;

blowers; evaporator coils; digital thermostat/controllers; and wiring from the newly installed panels to the new units.
