Specifications include, but are not limited to: The Adult Correctional Facility (ACF) Men’s Section, located at 1145 Shenandoah Lane in Plymouth, MN, was originally built in 1930 and encompasses over 270,000 square feet. The building is heated by three (3) dual-fuel 250-horsepower steam boilers, originally installed in the 1930’s with subsequent burner upgrades. Currently, the building’s heating needs are met through hot water, facilitated by steam-to-hot water exchangers and hot water boilers. The project consists of installing a dual-fuel natural gas/fuel oil condensing boiler plant designed to efficiently serve the entire facility. This includes the integration of hot water piping into the existing infrastructure tied to the steam-to-hot water heat exchangers which are to be demo’d as noted on the mechanical plans. One (1) of the existing steam boilers has been demo’d by the Owner as noted on the mechanical plans to make room for two (2) of the new hot water boilers. The addition of two (2) hydronic heaters for the boiler room’s freeze protection shall also be included. Four (4) 4-million BTO boilers are being pre-procured by the Owner and the Contractor is to install two (2) of these boilers now while making accommodations for the future two (2) boilers by providing tie-in points in the new dual-fuel boiler heating water loop. Hot water pumps and all appurtenances as noted on the plans shall be provided and installed by the Contractor.
