The Work of Project is defined by the Contract Documents and consists of but is not limited to the following: 1. Background: Existing HVAC and HV units on the Scarlet and Diamond Oaks buildings were installed in the late 1990's, with adapters on the original concrete roof curbs. The replacement units were manufactured by Engineered Air, are R-22 compressors for AC, are gas for heat and are nearing the end of their service life. Scarlet Oaks phases 1 & 2 have been completed. Phase 1 on the Diamond Oaks campus is in construction and due to be complete in August. This project is Phase 2 on the Diamond Oaks campus. 2. The units under Diamond Oaks Phase 2 are HV units and include gas heat. Two of the units are smaller in size than the previous units and the remainder are are generally likefor-like replacements in heating and ventilating capacity. The units are part of this contract to be provided by the Contractor and are NOT being prepurchased by Great Oaks. This contractor is to purchase, and receive the units, protect and stage them for installation, and install them after school is out in May of 2026, but before the substantial completion date. 3. Space onsite is limited until classes end May 29, 2026 and units cannot be staged on site until after classes are out.

Contractor may elect to prepare units for installation while in the yard including installation of controls.
