Redevelopment of Block 37
The Redevelopment of Block 37 is a significant mixed-use retail, entertainment, office, hotel, residential and transit project located in downtown Chicago. Thornton Tomasetti is the structural engineer for three segments of the project, working with three different owners and two architects. The 17-story Media Office Tower encompasses 550,000 square feet of Class A office space and includes a street-level, state-of-the-art television and radio station broadcast and operations center.
The Retail portion of the project comprises 70% of the site and utilizes an up-down construction technique. The Retail / Transit Center includes 400,000 square feet of retail on five levels above ground and four below-grade levels for parking and transit functions. A challenging aspect of the transit center is to interconnect two existing subway tunnels with the new center. A 35-story, 600,000 SF residential component will complete the facility and will be built above the five-story retail base.
