Project Name:
Chicago State University—15KV Service Upgrade
Chicago, IL
Start/Scheduled Date of Completion Date:
2014 - 2020
Project Scope:

Project included a complete 15,000 volt (15KV) service upgrade to the Administrative building, Performing Arts Center, Laboratory and General Academic spaces. 

Equipment for all buildings included unit substations, including high voltage switches, dry-type transformers, distribution panels with main breakers, and motor control centers. In Building D, the Emergency Generator was replaced, as well. Work also included re-cabling of the distribution system from aluminum to copper, replacing the lighting load centers, and replacing the medium voltage distribution cable.

Building outages occurred during the summer, with only two buildings being available for two-week intervals. These buildings were fed electrically from existing switchgear in an eighth building, in a daisy chain configuration at the high side of the unit substations in each building. To maintain power to the buildings not scheduled to be offline, BEI worked closely with ComEd to coordinate feeder loading. Temporary generation was provided to maintain building operations during construction, limiting total building outages to the short intervals prescribed in the Contract Documents.

Particular care had to be taken not to disturb any potential asbestos-containing materials (ACM). Workers exercised extreme caution to avoid damaging the material, as any disruption would immediately launch an exhaustive and project-delaying protocol for containment.

*Project incurred a (4) year delay due to the State of Illinois budget crisis.
