TORONTO, Aug. 4 (UPI) — Glass cascaded onto downtown streets from a second Toronto high-rise building this week as engineers try to determine what’s causing the incidents.
The most recent shower of glass came from the 16th floor of the 42-story Festival Tower Tuesday night, the Toronto Star reported. No one was injured, but a side street remained closed Thursday with scaffolding erected to protect pedestrians.
An entire glass panel fell from the building in May, but was stopped before hitting the sidewalk by an overhang, the newspaper said.
Another downtown high-rise is also having problems with large glass balcony panels shattering, most recently Monday, when two panes rained down.
That 37-story condominium has had eight glass partitions disintegrate since December. The city has ordered all of them removed and the developer said it could take months for replacements to be installed.
Engineers told the Star and the Canadian Broadcasting Corp. the most common reasons for glass to shatter are imperfections in the glass or improper installation that doesn’t allow for heat expansion and cold contraction.
Toronto has had near-record high temperatures this summer.
