The Baird Center (formerly the Wisconsin Center) in downtown Milwaukee underwent a major expansion and modernization to meet demand for the space. The convention and exhibition center added over 100,000 sf to the main exhibit hall, 30,000 sf rooftop ballroom with exterior terrace, new meeting rooms, and parking structure. Steel erection for the project had several logistical challenges and unique design elements that required a collaborative approach between steel erector Cullen-Smith and construction engineer CSD Structural Engineers. The session will provide an overview of challenges and solutions that led to the successful completion of the project.
