Helena Shop Boiler Replacement

The State of Montana Department of Transportation is seeking a sealed‑bid contract to replace the existing boiler in the Helena Maintenance Shop with two new high‑efficiency commercial condensing boilers, complete with associated piping, pumps, combustion‑air ducting, and integration to the existing building control system. The scope includes demolition of the existing boilers, installation of two Lochinvar Crest FB‑1501 units, primary/secondary loop configuration, new mechanical pads, gas pressure regulation, electrical wiring, flue installation, and startup/training by a manufacturer’s representative. An addendum issued on September 3 2026 clarifies that only Lochinvar Crest boilers may be used, that Johnson Controls will remain the DDC contractor, and that a site walk‑through was conducted on that date. The work must be completed by December 31 2026, and bids are accepted through September 30 2026. • Replace existing boiler with two Lochinvar Crest FB‑1501 condensing boilers. • Provide new primary/secondary heating‑water loop, piping, pumps, and combustion‑air ducts. • Integrate boilers with existing Johnson Controls DDC system and emergency shutdown button. • Complete installation, testing, and training by 12/31/2026; all work must be performed under a sealed‑bid IFB.
