The article talks about a method of dismantling skyscrapers floor-by-floor, lowering the roof as you go. Lots of people tweeting about this technological marvel.
Massive reduction in release of dirt and debris to the environment. The technique has been developed in Japan, where
“…there are 797 skyscrapers over 100 metres tall, around 150 of which will be between 30 and 40 years old in the next decade, says Ichihara. This has historically been the age when such buildings are earmarked for demolition, but conventional methods are not suitable for such tall skyscrapers.” (New Scientist)
The real issue for me is why in the world so many massive buildings are built with a 30-40 year lifespan! That would be the real cause for environmental concern! (Me, I am unapolgetic about my love for tall buildings…)
