Thornton Tomasetti, the international engineering firm, announces that it is the engineer of record for Tilt, a moveable platform that will incline out from the 94th floor at 360 CHICAGO (formerly John Hancock Observatory) and offer patrons a bird’s eye view of the Chicago skyline. Tilt is currently under construction and is scheduled to open this spring.
• Tilt consists of a stationary base structure and a 26-foot-wide movable platform that is controlled by three overhead hydraulic actuators. It is approximately 1000 feet above street level.
• Up to eight people will be able to stand in partitions along the platform and look down through the full-height tempered glass panels.
• Thornton Tomasetti designed the operable steel and glass structure and evaluated the steel framing of the 1960s-era building to verify its capacity to support it.
• Since its completion in 1970, the John Hancock Center stands as the pre-eminent address for local, national and international business. With its significant architecture and captivating views of four states, the John Hancock Center offers 897,000 square feet of Class-A commercial office space.
In addition to Thornton Tomasetti, 360 CHICAGO owner Montparnasse 56 Group has also employed Cupples as the fabricator/erector of Tilt. Turner Special Projects served as general contractor.
