Description
The project involves a complete replacement of the mechanical‑room HVAC plant at the F. Wayne Hill Water Resources Center Operations Building in Buford, GA. The contractor must supply, install, and commission three air‑handling units, two chilled‑water pumps, all variable‑air‑volume terminal units, associated ductwork, piping, electrical and control systems, while providing temporary cooling to keep the occupied building functional. The scope also includes demolition of existing equipment, construction of a concrete equipment pad, integration with the existing building‑management system, full commissioning, operator training, and delivery of hard‑copy and electronic O&M manuals.
• Replace three AHUs (including relocation of the mezzanine unit) and two chilled‑water pumps, and install all VAV terminal units.
• Provide temporary cooling units and execute phased installation so the building remains operational 24 × 7.
• Submit shop drawings, obtain approvals, and install ductwork, piping, electrical, and control hardware.
• Perform start‑up, testing, balancing, a 7‑day post‑start‑up performance period, and provide on‑site training.
• Meet bonding and insurance requirements (5 % bid bond, 100 % performance/payment bonds, A‑7 bond rating, specified insurance endorsements).
