Since 2010, the Burj Khalifa in Dubai has held the title of world's tallest structure at 2,716 ft. The Vincom Landmark 81 tower in Ho Chi Minh City, Vietnam, is the smallest structure on the list, standing at 1,513 feet.
The current record holder is the Trump Tower in Chicago, which rises 853 feet to its tip. Other notable buildings that have topped this list include the World Trade Center in New York City, the Petronas Towers in Kuala Lumpur, Malaysia, and the Taipei 101 in Taiwan.
The first skyscraper is said to have been built by Daniel Burnham and John M. Root in Chicago in 1892. They called their creation "The Great American Hotel". It was later renamed the Tribune Tower after the newspaper that built it.
The second skyscraper was built a few years later by William Henry Weber in St. Louis. It too was called "The Great American Hotel" but today is known as the Old Post Office Building because it now houses some government offices.
In 1903, the third skyscraper was built by Henry Hobson Richardson in Boston. It too was called "The Great American Hotel", but today is known as the Richardson Building because it now houses some government offices.
In 1908, the fourth skyscraper was built by Walter Curtiss in Cleveland.
The 828-metre (2,717-foot) tall Burj Khalifa in Dubai has held the title of tallest building since 2010. The Burj Khalifa has been designated as a "megatall," or the world's tallest structure.
|City||Ho Chi Minh City|
The world's tallest building, at 2,723 feet (829.84 meters), is the Burj Khalifa (previously Burj Dubai) in Dubai, United Arab Emirates. The second tallest building, by volume, is the World Trade Center Twin Towers in New York City. When completed in 1972, the twin towers were the highest buildings in the world.
The third tallest building, by height, is the Shanghai Tower (formerly the Shanghai World Financial Center). When it is finished in 2016, it will be 828 m (2,722 ft) tall. The fourth-tallest building is the Petronas Tower in Kuala Lumpur, Malaysia. At 632 m (2,071 ft) it is taller than Chicago's Willis Tower (formerly the Sears Tower). The fifth-tallest building is the Pinnacle Building in Toronto, which at 544 m (1,700 ft) is only slightly shorter than Chicago's John Hancock Centre (formerly the John Hancock Center).
The sixth-tallest building is the Jianguomen Tower in Beijing, which at 518 m (1,678 ft) is nearly as tall as Chicago's John Hancock Center. The seventh-tallest building is the HSBC Headquarters in Hong Kong, which at 468 m (1567 ft) is taller than Chicago's Willis Tower but not by very much.
The Burj Khalifa At 829.8 meters, the Burj Khalifa skyscraper is the world's tallest building (2,722 ft). Guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electrical transmission towers, and bridge support towers are among the structures included. The list is limited to functional buildings over 40 meters high, which were constructed after the Taipei 101.
The second question is easier to answer. The current record holder is the Tatiara Island Wind Farm, which consists of six 200-metre-high turbine generators installed on an island near Port Douglas, Queensland, Australia. The wind farm was built by Imerys who also supplied the titanium housing for the turbines. It started operating in December 2001 and its total capacity is 30 megawatts (MW). There are plans to increase this capacity to 50 MW in late 2003 or early 2004. The estimated cost is $20 million.
Here are the other candidates: the Taiwan Telecommunication Corporation Building (TTCC) in Taipei has a height of 556 feet (170 meters), while the Shanghai World Financial Center (SWFC) is only 498 feet tall (150 meters). Both buildings are luxury hotels currently under construction. When they are completed in 2009 and 2010 respectively, they will be the first skyscrapers in Asia to exceed 500 meters in height.
With a height of more than 2,716 feet, the Burj Khalifa is the world's tallest skyscraper and highest free-standing structure. It is also the most expensive building in history to build into the sky, costing $1.5 billion. The office tower holds 49 floors above the ground floor and has a total area of 535,000 square feet (50,000 m²). It was designed by British architect F.R.I. Crawford and constructed by the Burj Dubai LLC, which is owned by the government of Dubai.
The Burj Khalifa was intended to be the centerpiece of the "World Islands" mega-development, but this project was cancelled after its estimated cost of $750 million was found to be too high. Instead, the building's owner, the Emir of Dubai, announced plans to build another similar tower, the Sheikh Zayed Grand Mosque. The new tower will be the largest mosque in the world upon completion in 2014.
The Burj Khalifa was inspired by the tall buildings in Mumbai, India. It is believed that its creators sought to create a new icon for Dubai's tourism industry - one that would be unique yet familiar to many travelers. The building's height also represents the pinnacle of human achievement through science and technology.
Dubai The world's current tallest structure, the Burj Khalifa in Dubai, reaches 2,716 meters into the sky, and new skyscrapers are being built in Asia and the Middle East every year. China has eight of the top fifteen tallest skyscrapers. India has two buildings in the list.
Chicago The Willis Tower (formerly known as "John Hancock Center") is the second-highest building in the United States and third-highest in the world. It was also the first high-rise building in Chicago to be constructed since the Silver Building in 1930. The 1,331-foot (411 m) tall, 49 stories high structure holds the record for the highest occupied floor area ratio (the proportion of floor space to building volume) of any building in North America. The record was previously held by New York's Rockefeller Center with a FARA of 0.52. The John Hancock offers one of the best views in the city because all of Chicago's major landmarks are within view from its observation deck: the lake, the skyline, and even part of Wisconsin beyond it.
Seattle The Petronas Towers are twin office towers in Kuala Lumpur, Malaysia, that are the tallest buildings in Southeast Asia. They are also the fifth and sixth tallest buildings in the world. The taller tower measures 998 feet (300 m) while the shorter one is 888 feet (272 m).
The world's current tallest structure, the Burj Khalifa in Dubai, reaches 2,716 meters into the sky, and new skyscrapers are being built in Asia and the Middle East every year. Shanghai's Pudong International Airport is now the world's busiest airport by passenger traffic.
The original height of the Chrysler Building was 1,046 feet, but it was destroyed by a fire in July 1931. The rebuilt tower was again surpassed by another skyscraper just five years later. The Empire State Building is now recognized as the world's first true skyscraper because it remains the highest building in New York City.
The RIchard Rogers-designed Tribune Tower is the second-highest building in Chicago after the Willis Tower (formerly known as the Sears Tower). The third-highest building in the city is the John Hancock Center which was designed by Mies van der Rohe. It contains an observation deck on the 100th floor called Mies van der Rohe Park Bridge Viewing Platform.
Tallest buildings are found in Asia and the Middle East. There are three countries with at least four skyscrapers each: China, India, and Pakistan. Israel, Japan, South Korea, and Taiwan also have three skyscrapers each.
There are several factors that go into determining how high a building can be.
