HVAC LOOP REPLACEMENT AT THALIAN HALL

The City of Wilmington is replacing the hydronic HVAC loop that serves Thalian Hall. The scope includes removing existing chiller and boiler loop piping, installing new pipe from the vertical mains to six fan‑coil units, adding shut‑off valves in the mechanical room, insulating and painting the new pipe, and providing labeling. Work must be performed with minimal HVAC downtime, comply with ASTM and local code requirements, and be performed by a contractor on the City’s vendor list with appropriate insurance and licensing. • Remove and replace all loop piping (≈ 420 LF per line) from vertical mains to six first‑floor units. • Install isolation valves inside the mechanical room, re‑insulate, paint, and label all new pipe. • Follow City shutdown/start‑up protocols, maintain a clean site, and provide required insurance and licensing documentation.
