Replacement of HVAC Systems at the F. Wayne Hill Water Resources Center Operations Building

This solicitation calls for a full replacement of the HVAC system serving the Operations Building of the F. Wayne Hill Water Resources Center. The work includes demolition of existing equipment, installation of new air‑handling units, variable‑air‑volume terminal boxes, chilled‑water pumps, associated ductwork, piping, electrical and control systems, temporary cooling provision, commissioning, training, and delivery of complete O&M documentation. The building must remain occupied 24/7, requiring phased execution and temporary climate control. The contractor must also meet extensive bonding, insurance, and licensing requirements, and must provide a signed addendum with the bid. • Replace three AHUs (including relocation of a mezzanine unit), all VAV boxes, and two chilled‑water pumps. • Supply and install a Niagara‑based DDC control system, integrate with the existing BAS (Carrier i‑Vue), and replace fans, VFDs, and pressure sensors as clarified in later addenda. • Perform demolition, concrete pad construction, coating, fire‑damper installation, and full commissioning with a 7‑day operational verification period.
