MADTC is a 1500 seat performing arts theater. The structure extends from 10' above street level down below the second sub-street level and abuts structures on three sides, one of which is the new band shell. On the fourth side, it fronts lower Randolph Street. Except for the entry lobby and raised area over the stage, the entire roof is part of the park and covered with soil and plantings weighing up to 500 psf in some areas.

CEG teamed with Prestress Services, Inc. to value-engineer a structural solution in precast as the cost and schedule of a domestic steel frame proved unworkable. The main roof consists of 108' bulb tees carried by 30" x 54" girders and 30" columns creating a 65' high audience hall above stage level.

The project is scheduled for completion in July 2003 and it will be a cornerstone of the magnificent new Millennium Park.
