This contract awards a single contractor the responsibility for removing the existing chiller system at Rock Hill High School and installing a new, full‑capacity chiller package, including associated piping, valves, and a BACnet networking router. The scope also incorporates a $10,000 allowance for a temporary chiller if the existing unit fails before the new equipment is operational, and mandates the installation of an HVAC water‑treatment system that must meet stringent water‑quality parameters and provide one year of chemical supply and monthly testing reports. The contractor must coordinate crane usage to avoid occupied buildings, finish indoor piping to match existing aesthetics, and comply with detailed specification sections (01 1030 and 23 0603).
