Building a 1,000-foot Panorama
Visitors to Chicago’s fourth tallest building, 875 North Michigan Avenue, can test their nerves in TILT, an enclosed glass and steel movable platform that allows up to eight visitors to angle away from the building. At 1,000 feet, TILT gives thrill-seekers a look down on Chicago and a vista of Lake Michigan and four states.
We designed the structure and kinetic system for the platform. The project was completed in 2014.
Highlights
- TILT comprises a stationary base and movable viewing platform of build-up steel sections.
- Three overhead hydraulic actuators extend to pivot the platform 30 degrees beyond the face of the building.
- The viewing window is several layers of reinforced, fully tempered glass panels.
- A partial roof formed by reinforced glass protects the space from weather and debris.
- Visitors have handrail grips on both sides and waistband for additional support as needed.
