Demolish Building Without Bomb

The pedestrian crossing in Tokyo's Akasaka neighborhood began to realize there was something odd about Grand Prince Hotel Akasaka that is standing there. Hotel turned out to be as high as 40 floors shrink so half.

This is a how to demolish skyscraper: no explosives such as those commonly used today. Slowly but sure, without the sound of explosions and smoke rising high, it began to be stripped. Grand Akasaka Prince Hotel was built in the 1980s with 140 meters high. This hotel is a symbol of a decade full of glory when the Japanese economy was very prosperous and they are the motor of the world economy.

Now, the heyday had passed. Every 10 days, the hotel was reduced 2 floors or about 6.4 meters. Tasei Corp. has a method for isolating noise and dust resulting from the demolition. In addition, they also recycle energy pent up in a skyscraper.

How do they do it? The engineers reinforce the top of the building with a concrete block and then reduce the height of the building. Concretes was left in place and then used as a flexible cover that can be derived by relying on external support.

Currently, there are 15 hydraulic jack used to prop up this cover during the unloading process runs floors by floors. The material is crushed and then separated and recycled where possible.

In its heyday, Akasaka Castle (Japanese pronunciation to refer to the Akasaka Prince), is the gathering place of the upper class in Tokyo. Guests do not hesitate to pay hundreds of dollars for their stay in a luxury suite and Christmas Eve package for couples are also in great demand.

This situation has changed since the 1990s when the explosion occurred in the stock market and property market of Japan. Luxury hotels are no longer crowded by guests and they should strive to bring in customers.
