The Donegal Mutual Insurance Boiler House replacement included demolition of the existing maintenance building. In its place features a 3,774 square foot Maintenance and Boiler Plant Building. The new boilers within the plant replaced the existing boilers located in the main building. The new boilers will be supplied natural gas with a fuel oil back-up system allowing for future building expansions with the capacity to add additional boilers if needed. The project also involved the addition of a new emergency back-up generator that is be located adjacent to the Boiler Plant along with a revised layout of the parking areas.
