The Kajima Corporation, a Japanese civil engineering company, has started utilizing a demolition technique that dismantles a skyscraper from the ground up. Using a system that is not fully explained, the building’s support columns are replaced with massive jacks. The highly computerized system lowers the entire building after the bottom floor is demolished. By using this format, crews are able to easily separate recyclable construction materials and drastically cut down on dust pollution. Amazingly, this system is based on Daruma-Otoshi, an ancient Japanese game where a small hammer is used to knock out the lowest piece in a stack of colored blocks. What’s next, a construction technique based on Chutes and Ladders?
