How to demolish a building by reducing

Passers-by in the busy district of Akasaka in Tokyo began to notice something unusual about the 40-storey high hotel: reduced and "turned" in the double lower object.

Slowly but surely, without a single shred of explosions and dust - which is always accompanied by the demolition of skyscrapers - all hotel disappears.
"In the scheme of demolition, the building is reduced or disappears, and it almost does not notice," said the AFP manager of construction company "Taisel" performing this project, Hideki Ićihara.
"Grand Prince Hotel Akasaka" was built in the eighties and with a height of 140 meters is the symbol of the extravagance of the decade, when the Japanese had "money to throw away," Japan and the economic "ruled".
Now, the hotel is falling: ten days lost every 6.4 meters or two floors, says Ićihara.
The project of "Taisel" new ecological destruction process, designed to minimize noise and dirt, and recycled energy compressed into a high building.
Engineers have increased the top floor with steel beams and it is part of the hotel, which will remain as a "criss-roof" demolition by the end of the reduction, working your way down. Such as roof cover protects the lower floor in the process of dissolution. Is set to 15 hydraulic connector where the roof-cover is now "sitting", while workers removed floor by floor hotel which was once a symbol of luxury.
"Retaining this 'cap' on top of the building, significantly suppress noise and dust," says Ićihara.
Material remaining demolition sort in the group and, where possible, recycled. Scrap down through central drain, "well".
Thirty Hotel - which locals affectionately call "Aka Puri" - was once a symbol of Tokyo's flashy lifestyle. Customers are paying hundreds of dollars for a "sea bed" in luxury rooms and suites.
The style, however, disappeared at the beginning of the nineties, and many luxury hotels in Tokyo are - in parallel with changes in economic conditions - led the fight to keep their guests.
A spokesman for the hotel owner said that the hotel management is pleased quieter and cleaner version of the crash.
"People are like Aka Puri. Many people just gotten married at that hotel," says South Jasutake from "Seibu property" - the company which now plans to build on the same site a new hotel and business center.
"It's nice to see that the building disappears in such a clean way," he concludes.
Completion of the demolition of the hotel is expected in June.
