Project 2790 RFB Museum HVAC Upgrades

The County is seeking a qualified contractor to design, supply, and install a full HVAC control‑system upgrade at the Neville Public Museum. The work converts the existing pneumatic HVAC controls to a modern Direct Digital Control (DDC) system, installs new sensors, actuators, VAV boxes, and associated power/data cabling, and performs demolition, insulation repair, and ceiling restoration while the museum remains occupied. The contractor must phase the work so that only one HVAC unit is shut down at a time, coordinate closely with museum staff, and deliver a fully operational system before the winter heating season. • Replace all pneumatic thermostats, humidistats, dampers, and actuators with BACnet‑compatible DDC devices (Tridium/Niagara platform). • Install new VAV boxes, butterfly dampers, and retrofit kits (e.g., Trane RIRO) and provide all required power and data infrastructure. • Provide phasing plan, on‑site protection, weekly cleaning, and a minimum four‑hour on‑site training for museum personnel; submit as‑built and O&M documentation within 60 days of substantial completion.
