Floor-by-Floor Demolition
Normally when tall buildings are destroyed, there is a lot of explosion and a lot of dust, but Gizmodo reports on Kajima’s floor-by-floor slow demolition that does things a little differently
How do they do it? Gizmodo explains:
How do they do it? First they replace the support pillars at ground level with computer-controlled metal columns. Then, a crew carefully demolishes by hand the entire floor, leaving the structure resting on the mechanic pillars, which then go down slowly until the next floor is at ground level. They replace again the support pillars with the mechanic ones, destroy that floor, and repeat the operation until they get rid of all the floors. This makes it look as if the building is shrinking in front of you, or being swallowed by the street.
You can watch the process here:
One of the best parts of this process (called daruma-otoshi), aside from the eerie cool, is that in reduces the environmental impact of the demolition process. For more: Floor-by-Floor Demolition Blows Minds, Saves Environment.
