Chinese Firms Claims It Can Build World's Tallest Tower in 90 Days

An anonymous reader writes "Even since the current world's tallest builing — the Burj Khalifa in Dubai — was completed, there has been a constant battle to build the world's next tallest building. The current record holder stands tall at 828 meters and took five years to build, but a Chinese company called Broad Sustainable Building aims to smash that record by building the 838 meter Sky City tower, in Changsa, China in a mere 90 days. BSB plans to use prefab building techniques to construct the tower in record time."
