Skyscraper
A skyscraper is a tall, continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least or in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.
Burj Khalifa
The Burj Khalifa (known as the Burj Dubai prior to its inauguration in 2010) is a skyscraper in Dubai, United Arab Emirates. It is the world's tallest building. With a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding antenna, but including a 242.6 m spire) of , the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009, supplanting Taipei 101, the previous holder of that status.
One World Trade Center
One World Trade Center, also known as One World Trade, One WTC, and formerly called the Freedom Tower during initial planning stages, is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City. Designed by David Childs of Skidmore, Owings & Merrill, One World Trade Center is the tallest building in the United States, the tallest building in the Western Hemisphere, and the seventh-tallest in the world.
Modern architecture
Modern architecture, or modernist architecture, was an architectural movement or architectural style based upon new and innovative technologies of construction, particularly the use of glass, steel, and reinforced concrete; the idea that form should follow function (functionalism); an embrace of minimalism; and a rejection of ornament. It emerged in the first half of the 20th century and became dominant after World War II until the 1980s, when it was gradually replaced as the principal style for institutional and corporate buildings by postmodern architecture.
Sky lobby
A sky lobby is an intermediate interchange floor in a skyscraper where people can change from an express elevator that stops only at the sky lobby to a local elevator that stops at a subset of higher floors. When designing supertall buildings, supplying enough elevators is a problem – travellers wanting to reach a specific higher floor may conceivably have to stop at a very large number of other floors on the way up to let other passengers off and on.
Taipei 101
Taipei 101 (; stylized as TAIPEI 101), formerly known as the Taipei World Financial Center, is a skyscraper in the capital Taipei, Taiwan. The building was officially classified as the world's tallest from its opening in 2004 until the 2010 completion of the Burj Khalifa. Upon completion, it became the world's first skyscraper to exceed a height of half a kilometer (about 0.3 miles). Taipei 101 is the tallest building in Taiwan. The elevators of Taipei 101 that transport passengers from the 5th to the 89th floor in 37 seconds (attaining ) set speed records.
Alain Robert
Alain Robert (born as Robert Alain Philippe on 7 August 1962) is a French rock climber and urban climber. Known as "the French Spider-Man" or "the Human Spider", Robert is famous for his free solo climbing, scaling skyscrapers using no climbing equipment except for a small bag of chalk and a pair of climbing shoes. Because authorities do not normally give him permission for such dangerous exploits, Robert will appear at dawn on the site of whichever giant skyscraper he has chosen to climb.
Manhattan
Manhattan (mænˈhætən,_mən-) is the most densely populated and geographically smallest of the five boroughs of New York City. The borough is coextensive with New York County, one of the original counties of the U.S. state of New York. Located near the southern tip of the State of New York, Manhattan is based in the Eastern Time Zone and constitutes both the geographical and demographic center of the Northeast megalopolis and the urban core of the New York metropolitan area, the largest metropolitan area in the world by urban landmass.
Tube (structure)
In structural engineering, the tube is a system where, to resist lateral loads (wind, seismic, impact), a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground. This system was introduced by Fazlur Rahman Khan while at the architectural firm Skidmore, Owings & Merrill (SOM), in their Chicago office. The first example of the tube's use is the 43-story Khan-designed DeWitt-Chestnut Apartment Building, since renamed Plaza on DeWitt, in Chicago, Illinois, finished in 1966.
Chicago metropolitan area
The Chicago metropolitan area, also colloquially referred to as Chicagoland, is the metropolitan area containing the City of Chicago, which includes its surrounding suburbs and satellite cities. Encompassing 10,286 square mi (28,120 km2), the metropolitan area includes the city of Chicago, its suburbs and hinterland, that span 14 counties across northeast Illinois, northwest Indiana, and southeast Wisconsin. The MSA had a 2020 census population of 9,618,502 and the combined statistical area which spans up to 19 counties had a population of nearly 10 million people.
