The Dubai's Burj Khalifa is about to get overthroned as the world's tallest building by early 2013. A Chinese company called BSB that specializes in erecting pre-fabricated buildings will begin construction on the 838-meter tall Cky City in Changsa, China in just 90 days.
Ok here's the logic you need to digest, Burj Khalifa took 5 years to complete and the upcoming world's highest building will rise in just 90 days. Less than quarter time needed to construct the Burj Khalifa.
The BSB is the same company that constructs the 30-story hotel in just 15 days earlier this year.
The Sky City will be pre-built in a factory prior to its erection, but to piece it all together will take 90-days.
If everything goes well, the tower will be constructing on November 2012 and will be complete in January 2013. That'll put the Burj Khalifa as the second tallest building in the world.
