Northeastern Illinois University, Electrical Cable Replacement

Chicago, Illinois

Northeastern Illinois University in Chicago is a 19-building facility established in 1900. The College of Business Management is a 36,954-square-foot, one-story building established in 1961. Building B is a 36,374-square-foot, one-story building established in 1961. Building C is a 40,664-square-foot, nine-story building established in 1961. Building D is a 59,519-square-foot, four-story building established in 1961. Building E is an 84,082-square-foot, four-story building established in 1961. The Library is a 141,232-square-foot, six-story building established in 1978. Lech Walesa Hall is a 148,662-square-foot, seven-story building established in 1972. Bernard Brommel Hall is a 143,670-square-foot, three-story building established in 1971. 

The scope of work provides for replacement of aluminum cable and outdated tap boxes throughout the main campus. The aluminum cable carries 4160-volt current to all of the main campus buildings. A portion of the work will require that the electrical system be shut down, necessitating execution during closed hours.

Three medium voltage distribution circuits coming from two utility substations provide a normal and back-up primary feed at each of the campus substations. There is approximately 7,500 feet of distribution runs (23,000 LF of cable) to be replaced. The project will replace existing non-shielded cable with new shielded copper medium voltage cable as well as replace several 4160V tap boxes. Construction will be staged to replace one circuit at a time so all campus substations can remain energized by one of two primary feeds.
