Amazing Japanese demolition work

After 40 years, the Grand Prince Hotel Akasaka (140m) in Tokyo closed in 2011 in order to make space for new constructions.

This video show how a skyscraper can be demolished without using explosives. The building is lowered slowly and disappears from the skyline. This technology increases security for the workers and reduces sound and dust clouds remarkably. Amazing!

Summing up the video:
- Grand Prince Hotel was build in 1983, during the economic boom in Japan
- Top floor is held in place by temporary columns while two floors are being demolished at once and the building "shrinks" approx 6m in 3 hours.
- Japanese construction companies are competing in order to provide the best solution for demolishing old buildings from the 60ies that do not meet new construction standards.
