Designed by Gensler, Catalog is a five-story dining, retail, and entertainment hub located at the base of the 1970s Willis Tower. The repositioning project, which redevelops 388,900 sq ft of amenity space in this Chicago icon, also includes three new multistory entrances and twelve smaller retail entrances that welcome visitors to the tower’s new community. SGH provided structural engineering services for the design of the entrances.
