Built in 1929, the Mundelein Center is a 14-story concrete-framed structure on Loyola University’s Lakeshore Campus in Chicago, IL. The four-story space at the north end of the building, which originally housed a basement swimming pool, locker rooms, and a gymnasium, was transformed into a 230-seat performing arts theater with fully equipped scene-building shops and practice spaces and topped with a new glass ballroom at the roof level. The design and construction had to be sensitive to the Mundelein Center’s Landmark status.
Design challenges included the removal of three existing columns at the interface of the 14-story tower and the four-story structure to open the theater stage space by means of a new 13 ft (4 m) deep steel truss and complicated concrete column jacket transfers. To mitigate the deflections and limestone façade cracking, the transfer framing was preloaded with hydraulic jacks. Concrete bonded overlay was installed to strengthen the existing floor for the theater and stage loading. A stringent mockup and pulloff testing procedure were specified to ensure adequate bond and composite behavior of the existing concrete and the new overlay.
Additional structure modifications consisted of strengthening the existing steel roof beams with composite floor trusses for the addition of the one-story glass ballroom and terrace, installation of soil anchors at the foundation walls for below-grade excavation, and reinforcement of the existing pile foundations to accommodate increased loads and changes in load path.
The $22 million renovation project required in-depth knowledge of the existing structure’s behavior and careful consideration of the details. An aggressive design and construction schedule was established by the owner, requiring creative solutions for effective and timely constructibility.
