"In late 2011, Broad built a 30-story building in 15 days; now it intends to use similar methods to erect the world’s tallest building in just seven months. Perhaps you’re already familiar with Zhang’s handiwork: On New Year’s Day 2012, Broad released a time-lapse video of its 30-story achievement that quickly went viral: construction workers buzzing around like gnats while a clock in the corner of the screen marks the time. In just 360 hours, a 328-foot-tall tower called the T30 rises from an empty site to overlook Hunan’s Xiang River."
