SOM designs observation platforms that allow visitors to walk on the air. A new platform is planned for Chicago's Sears Tower.
The platforms are made op water-white glass, with no visible frame, and will stick out 1,353 feet above the street.
"In addition to delivering a gut-wrenching experience while ensuring no one actually plummets to the ground, the designers had to contend with one other factor: the window washing system.

In answer, SOM designed The Ledge's modules to retract into the building."
