History of CN Tower
The concept of constructing a tower in Toronto was proposed in the 1960s to provide better communication services. The tower was initially designed to be 540 meters tall but was later extended to its current height of 553 meters. The CN Tower officially opened to the public in 1976 and was once the tallest freestanding structure globally until 2007.
Original Design of CN Tower
The design of the CN Tower was inspired by the futuristic design of Buckminster Fuller’s geodesic dome. The tower features a tapering design, making it narrow at the top and wide at the bottom. The tower has a total of three observation levels, including an indoor observation deck, an outdoor observation deck, and the SkyPod, which is located at the topmost point of the tower.
Construction Period of CN Tower
The construction of the CN Tower began in 1973 and lasted for four years. The tower was built by a team of expert engineers and contractors who used state-of-the-art technology and equipment to complete the project. The construction of the tower involved several challenges, including the harsh weather conditions, the height of the tower, and the need to ensure the safety of the construction workers.
Materials Used in the Construction of CN Tower
The CN Tower was constructed using several materials, including concrete, steel, and aluminum. The tower’s foundation was constructed using 56,000 tonnes of concrete, while the tower’s main structure was built using steel and aluminum. The tower’s exterior cladding was made of stainless steel, which provides the tower with its distinctive silver appearance.
Structural Components of CN Tower
The CN Tower consists of several structural components, including the antenna mast, the tower’s main structure, and the foundation. The antenna mast is the tallest part of the tower, standing at 102 meters and is used for broadcasting and communication services. The tower’s main structure consists of several levels, including the observation decks, the elevators, and the SkyPod, which is located at the topmost part of the tower.
Challenges Faced during the Construction of CN Tower
Several challenges were faced during the construction of the CN Tower, including the construction of the tower’s foundation, which had to be built on top of an abandoned railway yard. The tower also had to be built in a location with harsh weather conditions, including strong winds and heavy snowfall. Safety was also a significant concern, and several safety measures were put in place to ensure the safety of the construction workers.
Features of CN Tower
The CN Tower features several unique features, including the world’s highest glass-floor paneled elevator, providing visitors with a unique view of the tower’s height as they ascend to the top. The tower also features the EdgeWalk experience, which allows visitors to walk on the outside of the tower, 1168 feet above the ground. The tower also has a revolving restaurant that offers visitors a breathtaking view of the city.
Durability of CN Tower
The CN Tower was designed and constructed to withstand extreme weather conditions, including strong winds, heavy rainfall, and snowfall. The tower’s foundation was designed to distribute the tower’s weight evenly, ensuring the tower’s stability. The use of high-quality materials and advanced construction techniques also ensures the tower’s durability.
Maintenance of CN Tower
The CN Tower undergoes regular maintenance to ensure its safety and durability. The tower’s exterior is cleaned regularly using high-pressure water jets, while the tower’s elevators undergo regular maintenance to ensure their smooth operation. The tower’s foundation is also inspected regularly to ensure its stability.
Conclusion
The CN Tower is a masterpiece of modern engineering and serves as a symbol of Canada’s innovation and technological advancement. The tower’s unique design, construction, and features make it one of the most popular tourist attractions globally, attracting millions of visitors every year.
