Split defensive covering on the Willis Tower’s glass survey deck, 410 meters over the ground level, prompts brief conclusion.
As indicated by nearby reports, every one of the four of the glass box seeing ranges of The Ledge fascination on the 103rd story of the 440 meter tall Willis Tower high rise were briefly shut yesterday morning for a “routine investigation”, succeeding reports of breaking glass.
Traveler Alejandro Garibay told NBC Chicago that he had been in one of the crates on the west side of the building with his sibling and cousins when they heard splitting. Pictures indicated a floor board that seemed to have broken.
An agent for the building said that there was no threat, and that the split surface was a layer of defensive covering over the structural glass intended to keep the glass from harm and scratching.
“This covering does not influence the structural uprightness of The Ledge in any capacity. Periodically, the covering will break, as it is intended to with a specific end goal to ensure the surface of the glass,” said Brian Rehme, an agent from advertising firm Fleishmanhillard.
By 4pm Chicago time, the fascination’s administrators had published that the defensive covering on box four of the ledge had been supplanted.
