CANADA - ONTARIO - TORONTO : The world's tallest building is an engineering wonder  Arguably Canada's most memorable icon and one that defines our ingenuity around the world, the CN Tower in Toronto (TORONTO HOTELS) has stood as a testament to Ontario's engineering prowess for over 30 years. Whether you call it the tallest building, tower or freestanding structure, at 553.33 meters nothing else on the planet has topped it yet."Each year, approximately two million people visit Canada's Wonder of the World, but few realize exactly how it was constructed," says Michael Monette, P.Eng., president and chair of the Ontario Society of Professional Engineers. "The project was massive, involving dozens of engineers from various disciplines including Civil, Soils, Foundation, Mechanical, Electrical, Structural and Broadcast engineering." Originally designed as a telecommunications hub, building the CN Tower was a vast and ambitious project that involved 1,537 workers who laboured 24 hours a day, five days a week for 40 months to completion. The engineering teams made sure the CN Tower was designed as a hollow core with a hollow leg structure in order for the building to be flexible. This is evident by the flexibility of the CN Tower during extremely high winds. The base of the CN Tower is anchored in bedrock - not just a set foundation. Once the foundation was ready in the spring of 1973, work began on the CN Tower's 335 meter concrete shaft, a hexagonal core with three curved support arms. This involved pouring concrete into a huge mold or "slipform." As the concrete hardened, the slipform, supported by a ring of hydraulic climbing jacks, moved upwards, gradually decreasing in size to produce the CN Tower's gracefully tapered contour. The CN Tower approached completion in March 1975, when Olga, the giant Erickson (formerly Sikorsky) aircrane helicopter, flew in to lift the 44 pieces of the antenna into place. The CN Tower was finished on April 2, 1975, and opened to the public June 26, 1976. FAIRMONT ROYAL YORK TORONTO HOTELS ONTARIO HOTELS Photo and article courtesy www.newscanada.com |
