China Is Stacking Buildings Like Lego in 28 Hours. Engineers Are Terrified.

A Chinese company can now stack a finished 10-story apartment building in 28 hours and 45 minutes, bolting factory-made rooms together like a giant piece of flat-pack furniture. The world calls it a miracle. I spent my whole working life around concrete and steel, and it worries me. Not because these towers have fallen. They haven't. It's because of what that speed quietly gives up. To go up in a day, a building like this has to seal its most important parts, the connections between the stacked rooms, behind the walls on the very first day, where no one can ever see them, inspect them, or fix them again. In this video I break down what actually goes up in 28 hours, why those hidden joints are the whole ballgame, and the four ways that bet can come due: through fire, through water, through an earthquake, and through an oversight system almost no outsider can check. From Broad Group's record-breaking towers in Changsha to the schools that fell in Sichuan and the one tower in Bangkok that came down from a quake a thousand kilometers away, this is the warning that comes before the ground moves, not after. If stories like this one matter to you, the kind of warning that stays buried until it's too late, take a second to subscribe. I'll keep bringing you the truth behind the things we build.
