Our firm was retained through a contractor of the NYC DEP to design and provide construction support on a boiler upgrade for the laboratory and office facility of Kingston, NY. The project consisted of replacing two 6000 MBH non-condensing boilers and associated pumps with three new 3000 MBH high efficiency condensing boilers as well as the replacement of an existing hot water storage tank, new pumps including boiler supply, HEX and glycol system pumps, and the replacement of existing chimneys. Challenges included designing a two-tiered pump array to maximize the available space in the boiler room and make provisions for temporary hot water service to the building during construction.
