Clark is delivering multiple projects to modernize and enhance the iconic Willis Tower Skydeck experience.

In 2021, Clark constructed a 55,500-square-foot entryway and exhibition area at Willis Tower. The museum-quality exhibits focus on Chicago’s eclectic architecture while leading to elevators that take visitors to the 103rd-floor observation deck – one of the busiest tourist attractions in Chicago. The scope of work also included improvements to the restrooms, security screening, and ticketing areas.

The Clark team is currently performing extensive upgrades to the observation tower elevators, including expanding the elevator machine room and installing new rescue openings, structural steel reinforcement, steel bridge platforms, and a welded wire screen partition through the 1,100-foot hoistway to separate the elevator cars. As part of the project, Clark is also demolishing the existing observation space and install new high-end finishes, a fifth observational glass box on the 103rd floor, and MEP systems, including an air handler system on the 104th floor.
