In the field of construction, China is leading the world, as of 2020, the country's construction companies have built seven 500m+ skyscrapers in their own country (with the ones topped out but not fully complete included), and is also building supertalls in some other countries. Chicago Spire was reported to have construction difficulties. As of now American construction companies have not built a single skyscraper taller than 500 meters (1640ft) yet, it's unknown whether their technology could complete a building that tall. For instance, in 1930s, the height of the Empire State Building was the maximum height achievable with the technology of that time. The height of a skyscraper is subject to the restriction of technology. So why America doesn't build tallest building again? Below are some main factors behind it. Moreover, many megatall skyscrapers have been successfully built in China, while America's tallest completed building by roof height is still Sears Tower ( One World Trade Center is not really taller than Sears Tower, its roof, highest occupied floor and observation deck are all much lower than that of Sears Tower, which is a building built in 1970s), megatall is still in vision stage in America.
With the current speed, the total number of skyscrapers above 500 feet in China will be 4 times of the number in America within a few years. Skyline of Chicago seen in 2017, Willis Tower has been the tallest building in the city for more than 40 years.Īmerica is the birthplace of skyscraper, in last century, most skyscrapers in the world were located within America, New York City and Chicago had been the most representative skyscraper cities, and the crown of World's Tallest Building had always been owned by buildings in America, until in 1997 when Petronas Towers in Malaysia overtook that crown from Sears Tower with their decorative spires.īut after that, Asian countries keep building more and more skyscrapers, Dubai, China, and some Southeast Asian countries are best examples, as in recent years the majority of newly built skyscrapers are located in these places.
