If only constructing a skyscraper were as easy as stacking Legos. Then, we’d be throwing together 200-story towers in a matter of weeks, just clicking blocks together until we got bored. But the idea isn’t so far-fetched: if China’s Broad Sustainable Building Corp. is doing its math and crossing its ts properly, it could be topping out a 2,749-ft.-tall skyscraper — the world’s tallest — in just three months.
Starting in January, the race will be on against what seems to be an impossibly short deadline. Broad is allotting just 90 days to construct the 220-story tower, dubbed Sky City, in the city of Changsha, in China’s southeastern Hunan province — meaning the building will go up at a rate of about five stories a day, according to Construction Week Online.
