WRF Building 75 Boilers and Heat‑Loop Improvements

The project modernizes the Wastewater Reclamation Facility’s Building 75 boiler plant and associated heat‑loop system. It requires phased removal of existing boilers, pumps, mechanical equipment, piping, controls, and SCADA screens, followed by installation of new dual‑fuel boilers, hot‑water circulation pumps, upgraded control panels, expanded piping, and associated electrical work, all while maintaining continuous plant operation. A temporary hydronic heating system must be provided during construction, and detailed coordination with existing plant utilities is required. • Replace five boilers (two non‑condensing Weil‑McLain units, three condensing Cleaver‑Brooks units) and install a master control panel (Heat Timer). • Upgrade hot‑water supply/return piping, pumps, expansion tanks, valves, and SCADA integration across Buildings 75, 90, 801‑803. • Provide a temporary boiler‑heat system, conduct extensive demolition of existing equipment, and ensure minimal shutdown of wastewater treatment processes. • Coordinate mechanical, electrical, and civil work, secure all required permits, and deliver complete as‑built documentation, O&M manuals, and training.
