The CN Tower, located in downtown Toronto, Ontario, Canada, is a communications and tourist tower standing 553.33 metres (1,815.39 ft) tall.[1] It surpassed the height of the Ostankino Tower while still under construction in 1975, becoming the tallest free-standing structure on land in the world. On September 12, 2007, after holding the record for 31 years, the CN tower was surpassed in height by the still-under-construction Burj Dubai.[2] It remains the tallest free-standing structure in the Americas and the signature icon of Toronto's skyline, attracting more than two million international visitors annually.[3] This article is about the Canadian province. ...

CN originally referred to Canadian National, the railway company that built the tower. Following the railway's decision to divest non-core freight railway assets, prior to the company's privatization in 1995, they transferred the tower to the Canada Lands Company (CLC), a federal Crown corporation responsible for real estate development. Since local residents wished to retain the name CN Tower, the abbreviation is now said to expand to Canada's National Tower rather than the original Canadian National Tower; however, neither of these are commonly used.[4] The Canadian National Railway (CN; AAR reporting marks CN, CNA, CNIS) is a Canadian Class I railway operated by the Canadian National Railway Company headquartered in Montreal, Quebec. ...

History

The concept of the CN Tower originated from a 1968 Canadian National Railway desire to build a large TV and radio communication platform to serve the Toronto area, as well as demonstrating the strength of Canadian industry, and CN in particular. These plans evolved over the next few years, until the project became official in 1972. The Tower would have been part of Metro Centre (see CityPlace), a large development south of Front Street on the Railway Lands, a large railway switching yard that was being made redundant by newer yards outside the city. Key project team members were NCK Engineering as structural engineer; John Andrews Architects; Webb, Zerafa, Menkes, Housden Architects; Foundation Building Construction and Canron (Eastern Structural Division).

At the time, Toronto was a boom town and the late 1960s and early 1970s had seen the construction of numerous large skyscrapers in the downtown core. This made broadcasting into the downtown area very difficult due to reflections off the buildings. The only solution would be to raise the antennas above the buildings, demanding a tower over 300 metres (984 ft) tall. Additionally, at that time most data communications took place over point-to-point microwave links, whose dish antennae used to cover the roofs of large buildings. As each new skyscraper was added to the downtown, former line-of-sight links were no longer possible. CN intended to rent "hub" space for microwave links, visible from almost any building in the Toronto area. The CN Tower can be seen from at least as far away as Gamble Street in Richmond Hill, Ontario, approximately 30 kilometres (19 mi) to the north, and from several points on the south shore of Lake Ontario, 48 kilometres (30 mi) to the south.

The original plan for the tower envisioned a tripod consisting of three independent cylindrical "pillars" linked at various heights by structural bridges. Had it been built, this design would have been considerably shorter, with the metal antenna located roughly where the concrete section between the main level and the Sky Pod lies today. As the design effort continued, it evolved into the current design with a single continuous hexagonal core to the Sky Pod, with three support legs blended into the hexagon below the main level, forming a large Y-shape structure at the ground level.


The idea for the main level in its current form evolved around this time, but the Sky Pod was not part of the plans until some time later. One engineer in particular felt that visitors would feel the higher observation deck would be worth paying extra for, and the costs in terms of construction were not prohibitive. It was also some time around this point that it was realized that the Tower could become the world's tallest structure, and plans were changed to incorporate subtle changes throughout the tower to this end.


Construction

Construction on the CN Tower started on February 6, 1973 with massive excavations at the tower base for the foundation. By the time the foundation was complete, 56,000 tonnes (61,729 ST) of dirt and shale were removed to a depth of 15 metres (49.2 ft) in the centre, and a base incorporating 7,000 cubic metres (9,156 cu yd) of concrete with 450 tonnes (496 ST) of rebar and 36 tonnes (40 ST) of steel cable had been built to a thickness of 6.7 metres (22 ft). This portion of the construction was fairly rapid, with only four months needed between the start and the foundation being ready for construction on top. is the 37th day of the year in the Gregorian calendar. ...

To build the main support pillar, a hydraulically-raised slipform was built at the base. This was a fairly impressive engineering feat on its own, consisting of a large metal platform that raised itself on jacks at about 6 metres (19.7 ft) per day as the concrete below set. Concrete was poured continuously by a team of 1,532 people until February 22, 1974, during which it had already become the tallest structure in Canada, surpassing the recently built Inco Superstack which was built using similar methods. In total, the tower contains 40,500 cubic metres (52,972 cu yd) of concrete, all of which was mixed on-site in order to ensure batch consistency. Through the pour, the vertical accuracy of the tower was maintained by comparing the slip form's location to massive plumb-bobs hanging from it, observed by small telescopes from the ground. Over the height of the tower, it varies from true vertical accuracy by only 29 millimetres (1.1 in).

In August of the same year, construction of the main level commenced. Using 45 hydraulic jacks attached to cables strung from a temporary steel crown anchored to the top of the tower, twelve giant steel and wooden bracket forms were slowly raised, ultimately taking about a week to crawl up to their final position. These forms were not only used to create the brackets which support the main level, but also as a base for the construction of the main level itself. The Sky Pod was built of concrete poured into a wooden frame attached to rebar at the lower level Deck, and then reinforced with a large steel compression band around the outside.


The antenna was originally to be raised by crane as well, but during construction the Sikorsky S-64 Skycrane helicopter became available when the United States Army sold off their examples to civilian operators. The helicopter, named "Olga", was first used to remove the crane, and then flew the antenna up in 36 sections. The flights of the antenna pieces were a minor tourist attraction of their own, as the schedule was printed in the local newspapers. Use of the helicopter saved months of construction time, with this phase taking only three-and-a-half weeks instead of the planned six months. The tower was topped off on April 2, 1975 after 26 months of construction, officially capturing the height record from Moscow's Ostankino Tower, and bringing the total mass to 118,000 tonnes (130,073 tons).

Two years into the construction, plans for Metro Centre were scrapped, leaving the Tower isolated on the Railway Lands in what was then a largely abandoned light-industrial space. This caused serious problems for tourists to access the tower. Ned Baldwin, project architect with John Andrews, wrote at the time that "All of the logic which dictated the design of the lower accommodation has been upset," and that "Under such ludicrous circumstances Canadian National would hardly have chosen this location to build."


Opening

The CN Tower opened to the public on June 26, 1976, although the official opening date was October 1. The construction costs of approximately CDN$63 million ($330 million in 2005) were repaid in fifteen years. Canadian National Railway sold the Tower prior to taking the company public in 1995, when they decided to divest themselves of all operations not directly related to their core freight shipping businesses. is the 177th day of the year (178th in leap years) in the Gregorian calendar. ...

As the area around the Tower was developed, particularly with the introduction of the Metro Toronto Convention Centre and Rogers Centre (known as the SkyDome before 2005), the former railway "wasteland" disappeared and the Tower became the centre of a newly developing entertainment area. Access was greatly improved with the construction of the SkyWalk in 1989, which connected the Tower and SkyDome to the nearby railway and subway station, Union Station. By the mid-1990s it was the centre of a thriving tourist district. The entire area continues to be an area of intense building, notably a recent boom in condominium construction.

The CN Tower consists of several substructures. The main portion of the Tower is a hollow concrete hexagonal pillar containing the six elevators, stairwells, and power and plumbing connections. On top of this is a 102 metres (334.6 ft) metal broadcast antenna, carrying TV and radio signals. There are two visitor areas: the main deck level (formerly known as SkyPod) located at 346 metres (1,135 ft), and the higher Sky Pod (formerly known as Space Deck) at 446.5 metres (1,465 ft),[6] just below the metal antenna. The hexagonal shape can be seen between the two areas; however, below the main deck, three large supporting legs give the tower the appearance of a large tripod.

Falling ice danger

A freezing rain storm on March 2, 2007 had resulted in a layer of ice several centimetres thick forming on the side of the tower and other downtown buildings. The sun thawed the ice, and winds of up to 90 kilometres per hour (56 mph) blew some of it away from the structure. There were fears that cars and windows of nearby buildings would be smashed by large chunks of ice. In response, police closed some streets surrounding the CN Tower. During morning rush hour on March 5, police expanded the area of closed streets to include the Gardiner Expressway 310 metres (1,017 ft) away from the tower, as increased winds blew the ice farther away, as far north as King Street, 490 metres (1,608 ft) away, where a taxicab window was shattered.

In August of 2000, a fire broke out at the Ostankino Tower in Moscow, killing several people and causing extensive damage. The fire was blamed on poor maintenance and outdated equipment. The failure of the fire-suppression systems and the lack of proper equipment for firefighters allowed the fire to destroy most of the interior and spark fears the tower might even collapse.

The Ostankino Tower was built 9 years before the CN Tower and is only 13 metres shorter. However, Canadian officials subsequently stated that it is "highly unlikely" that a similar disaster could occur at the CN Tower as it has safeguards that were not present in the Ostankino Tower. Specifically, officials cited:

  • the fireproof building materials used in the tower's construction,
  • frequent and stringent safety inspections,
  • an extensive sprinkler system,
  • a 24-hour emergency monitoring operation,
  • two 15,000-imperial gallon water reservoirs at the top which are automatically replenished,
  • a fire hose at the base of the structure capable of sending 600 imperial gallons a minute to any location in the tower,
  • a ban on gas appliances anywhere in the tower,
  • an elevator that can be used during a fire as it runs up the outside of the building and can be powered by three emergency generators at the base of the structure (unlike the elevator at the Ostankino tower, which seriously malfunctioned).[12]

Officials also noted that the CN Tower has an excellent safety record and that there has never been accidental fire in the Tower since it was opened in 1976.[12] Moreover, other tall structures built between 1967-1976, such as the Sears Tower, the World Trade Center (excluding the terrorist attacks), the John Hancock Center and the Aon Center also have excellent safety records, which suggests that the Ostankino Tower fire was a rare safety failure.

There are currently six proposals for towers whose final heights are to exceed the CN Tower's,[15] four of which are currently under construction. At the forefront is the Burj Dubai which surpassed the CN Tower in height in September 2007. The developers of Burj Dubai have kept the final planned height and number of stories a secret, but they have announced that it would stop somewhere above 2,684 feet (818.1 m). In North America, the Chicago Spire's height is currently planned to exceed CN Tower's height, currently planned at 2,000 feet (609.6 m).[16] The Freedom Tower, which is under construction in New York City is expected to be 12 m (39 ft) shorter in order to make the tower 1776 ft tall (1776 was the year the United States declared independence).

Controversy over the "World's Tallest" title

Guinness World Records has called the CN Tower "The world's tallest self-supporting tower" and "the world's tallest free-standing tower".[17][18] Although Guinness did list this description of the CN Tower under the heading "tallest building" at least once[18], it has also listed it under "tallest tower", omitting it from its list of "tallest buildings."[17] In 1996, Guinness World Records officially changed the CN Tower's classification to "World's Tallest Building and Freestanding Structure". Today, the Guinness World Records state the CN Tower as the "Tallest Freestanding Tower," because the Petronius Platform oil platform in the Gulf of Mexico is taller at 2,001 feet (609.9 m), yet most of the rig is underwater, earning it the title of tallest free-standing structure in the world. Emporis and the Council on Tall Buildings and Urban Habitat both list the CN Tower as the world's tallest free-standing structure on land, and specifically state that the CN Tower is not a true building, thereby awarding the title of world's tallest building to Taipei 101, which is 44 metres (144 ft) shorter than the CN Tower.[19][20] The tower's official web site, however, unequivocally claims it is the "world's tallest building".[21] Guinness World Records 2008 edition. ...

Although the CN Tower contains a restaurant, a gift shop and multiple observation levels, it does not have floors continuously from the ground, and therefore it is not considered a building by the Council on Tall Buildings and Urban Habitat (CTBUH), Emporis, or any other architectural authorities. The CTBUH defines a building as "a structure that is designed for residential, business, or manufacturing purposes. An essential characteristic of a building is that it has floors."[20] The CN Tower and other similar structures, such as the Ostankino Tower in Moscow, Russia, the Stratosphere Tower in Las Vegas, Nevada and the Eiffel Tower in Paris, France are categorized as "towers", which are free-standing structures which may have observation decks and a few other habitable levels, but do not have floors from the ground up.

Taller than the CN Tower are numerous radio masts and towers which are held in place by guy-wires, the tallest being the KVLY-TV mast in North Dakota at 628 metres (2,060 ft) tall, leading to a distinction between these and "free-standing" structures. Additionally, the Petronius Platform stands 610 metres (2,001 ft) above its base on the bottom of the Gulf of Mexico, However, only the top 75 metres (246 ft) of this oil and natural gas platform are above water, and the structure is thus partially supported by its buoyancy. Like the CN Tower, none of these taller structures are commonly considered buildings.

On September 12, 2007, the Burj Dubai, a hotel, residential and commercial building being built in Dubai, United Arab Emirates, finally succeeded in passing the CN Tower's 553.33 metre[1] height. The CN Tower held the record of tallest free-standing structure on land for over 30 years.[2] The tower now stands as the second-tallest free-standing structure on land in the world, and as the tallest completed structure.

CN Tower - Wikipedia, the free encyclopedia (2776 words)
The CN Tower opened to the public on June 26, 1976, although the official opening date was October 1st.
CN sold the Tower prior to taking the company public in 1995, when they decided to divest themselves of all operations not directly related to their core freight shipping businesses.
As the area around the Tower was developed, particularly with the introduction of the Metro Toronto Convention Centre and Skydome (known as the Rogers Centre since 2005), the former railway "wasteland" disappeared and the Tower became the centre of a newly developing entertainment area.
CN Tower: Information from Answers.com (1704 words)
CN originally referred to the Canadian National Railway, but following the railway's decision to divest non-core freight railway assets, prior to the company's privatization in 1995, the CN Tower was transferred to the Canada Lands Company (CLC), a federal Crown corporation responsible for real estate development.
In 1995, the CN Tower was declared one of the modern Seven Wonders of the World by the American Society of Civil Engineers.
The CN Tower is 13 metres taller than Moscow's Ostankino Tower, is almost twice as tall as the Eiffel Tower, and is the tallest member of the World Federation of Great Towers.
