Simpson Gumpertz & Heger (SGH) senior staff member Jared Brewe coauthored an article discussing the engineering challenges overcome during the Navy Pier Ferris wheel replacement project in Chicago, IL. In “Chicago’s Navy Pier Centennial Wheel” – the cover story of the July 2017 issue of STRUCTURE magazine – Jared and coauthors John Sheridan of James McHugh Construction and Ken Maschke of Thornton Tomasetti describe the teamwork and analysis needed to remove the site’s existing wheel and replace it with larger one, named the Centennial Wheel in celebration of the Pier’s 100th anniversary.
In the article, the authors explain several unique aspects of the project involving the Ferris wheel selection, structural design, and construction. “There was nothing typical or standard about the construction of Centennial Wheel,” the authors conclude. “While visitors may be most impressed by the new temperature-controlled gondolas, in-cabin video screens, and better views, the Chicago-based teams behind the wheel know the real accomplishment is in the engineering details: a 525-ton, 196-foot-high structure constructed over a fully-functional parking garage on a pier by more than 500 men and women in roughly 25,000 hours.”
