- Central Heating & Cooling Plant
Burns & McDonnell provided all design-build services for a new central heating and cooling plant for Wheaton College. The 10,000-square-foot project incorporated a large chiller room on one side of the facility and a boiler room on the other, separated by a common central control room and electrical room. The chilled water system includes two 600-ton electric centrifugal chillers and two future 1,200-ton electric centrifugal chillers for a total capacity of 3,600 tons. The steam boiler plant contains one 300-hp boiler, one 750-hp boiler and two future 750-hp boilers for a total capacity of 2,550 boiler hp.

The scope of work included expansion of the college’s utility infrastructure to convey steam and chilled water from the new heating and cooling plant to academic buildings, dormitories and athletic facilities throughout the campus. The infrastructure improvements consisted of a 12-inch diameter, direct-buried double wall, pre-insulated, steel piping steam main system; a 6-inch diameter, direct-buried double wall, pre-insulated, steel piping condensate main system; and 24-inch diameter, direct-buried HDPE chilled water pipes, as well as various upgrades to the college’s power distribution, potable water, sanitary sewer and storm sewer systems.
