Labor Day Weekend Maintenance

hgc

The Central Utility Plant of the Facilities Management Department on the Evanston Campus will be shut down to perform routine annual maintenance beginning Friday, September 1, 2017, at 6:00 p.m. Normal operations will resume on Monday, September 4, 2017, at 10:00 p.m. (Labor Day weekend). This shutdown is essential and is scheduled during this period to cause the least inconvenience to occupants of the affected buildings. There will be no deviation from this schedule.

The exact effect of this shutdown will vary from building to building; but, in general, those buildings normally serviced by the central steam and chilled water system will not have heating or hot water and will have no air conditioning except for science buildings. Shutdown details for science buildings are provided below.

If you have questions or require additional information, please contact Facilities Management:
