To another country! Vance Kelley, Treanor Preservation principal, and Julia Manglitz, Treanor Preservation project manager, recently travelled to Toronto, Canada to present a paper they co-authored at ASTM International’s Symposium on Masonry 2014.
While in Toronto they took in a few of the sights, including the CN Tower. The CN Tower is a 1,815.4 ft high concrete communications and observation tower in Downtown Toronto. It was completed in 1976, becoming the world's tallest free-standing structure and world's tallest tower at the time. It held both records for 34 years until the completion of Burj Khalifa and Canton Tower in 2010. It remains the tallest free-standing structure in the Western Hemisphere, a signature icon of Toronto's skyline, and a symbol of Canada, attracting more than two million international visitors annually.
In 1995, the CN Tower was declared one of the modern Seven Wonders of the World by the American Society of Civil Engineers. It also belongs to the World Federation of Great Towers, where it holds second-place ranking.
