China Begins Construction on the Tallest Building in the World

China is constructing the tallest building in the world in 90 days. Sky City is the name of the building and it's located in Changsha, Hunan province in South Central China. The total height of Sky City is going to be 838 meters, which is 10 meters taller than the Dubai landmark Burj Khalifa, the world's tallest building right now.

Surprisingly, the construction company, Broad Sustainable Building, announced that they would finish this only in 90 days. It took 5 years to finish building Burj Khalifa so this plan is incredible. In order to finish this on time, they have to construct 5 floors every day on average. It sounds unbelievable but to do so, they will use the 'prefabrication' technique in which blocks of the building are constructed offsite and then pieced together. As a result, it helps to reduce time to build.

The construction started in January 2013 and they anticipate finishing it in March 2013. It is going to have 220 floors and house 17,400 people as well as a selection of hotels, a hospital, several schools, and offices. Another surprising fact is that it will cost about $630 million, which is around a third of the cost for building Burj Khalifa.

One of the concerns about this building is safeness. However, Sky City will be able to stand magnitude 9.0 earthquakes. The 2008 Sichuan earthquake was one of the biggest recent earthquakes in China and it was magnitude 7.9. Therefore, it is obvious that Sky City is going to be strong enough to withstand massive earthquakes. Recently, China has been amazing the world by its announcements of astonishing projects and this is one of them that we keep our eyes on this month.
