Interesting demolition method
Kajima Corporation is demolishing two skyscrapers using a silent, clean and fast original method. In the video you’ll see how they replace the first floor columns with metal ones supported by an hydraulic system controlled by computer, they can make the whole building to go down one level and repeat the same process over and over:
This method is inspired by a traditional Japanese game called “daruma otoshi”:
Japan is a country where buildings are seen as something “temporary”, the average life-span of buildings-houses in Japan is around 20-30 years. In Great Britain I thing the average lifespan of houses goes up to 100 years. Buildings and houses appearing and disappearing in Japanese cities es very normal. At the beginning I was surprised how much my neighbourhood changed in a year or two, but now I think I’m used to. 30 years old buildings are considered REALLY old!
