Eco-Friendly Demolition In Japan Shrinks Skyscrapers Level By Level (VIDEO)

Posted: Updated:

Taisei Corporation, a construction company based in Japan, has devised a way to demolish skyscrapers without the explosive results and messy cleanup.

The eco-friendly demolition technique, called the Taisei Ecological Reproduction System (Tecorep), involves taking a structure apart from the inside, Wired reports.

Tokyo's Grand Prince Hotel Akasaka is the current target of demolition, and, in a recent time-lapse video, the 456-foot skyscraper appears to shrink 100 feet -- one level at a time.

According to the Japan Times, the hotel is the tallest building to be demolished in Japan to date. Since cranes -- the go-to technique for demolishing buildings -- cannot extend to reach the tops of skyscrapers much higher than 330 feet, Tecorep is the safest option of disassembly, the report notes.

Inside the building, jacks support the roof as floors are demolished from the top down, while an internal crane lowers materials and debris to the ground floor.

Conceived in 2008, Tecorep took at least a year and half for development. While other construction companies have launched their own methods of deconstruction, including razing buildings level by level from the bottom up, the system also saves energy and reduces carbon emissions by 85 percent, according to Wired.

The Grand Prince Hotel Akasaka closed in March 2011, since the building required drastic renovations; however, the hotel stayed open through June 2011 to house Fukushima evacuees, the Wall Street Journal notes. So far, the construction crew has demolished about 100 feet of the high-rise.
