About this file

This is a mechanical schedules document for an HVAC upgrade project at MacOnce Elementary School within Anchor Bay School District located in Casco, Michigan. The document, prepared by Peter Basso Associates, provides construction specifications and equipment schedules issued as of May 1, 2026, with Addendum No. 1 dated May 22, 2026. The project encompasses the installation and upgrade of multiple mechanical systems including centrifugal pumps, blower coil units, air-cooled condensing units, and packaged air-cooled liquid chillers. Key equipment specifications include two identical end-suction flexible coupling pumps (CP-9 and CP-10) serving the boiler room with 325 GPM waterflow capacity using propylene glycol solution, an air handling unit (AHU-2) with 1,015 CFM airflow capacity utilizing R32 refrigerant, an air-cooled condensing unit (CU-2) with 34.2 MBH capacity serving the AHU-2 system, and a primary chiller unit (CH-1) rated at 180.6 tons with six compressors operating on propylene glycol at design conditions of 95°F ambient temperature.

The schedules specify electrical requirements operating at 480 volts, three-phase power with various motor specifications and short circuit current ratings as required by the National Electrical Code. The chiller unit CH-1 is configured with 325 GPM chilled water flow capacity, propylene glycol 35 percent fluid type, operating temperatures between 56.3°F and 42°F, and includes six 69 RLA compressors with a minimum full load EER of 10.52 and IPLV rating of 17.42. All model numbers are specified from manufacturers including Bell & Gossett for pumps and Daikin for cooling equipment unless otherwise noted. The document establishes baseline mechanical specifications for the school district's chilled water pump and chiller upgrade project, with all equipment meeting applicable ARI standards and performance efficiency requirements.
