Japan’s revolutionary new way of demolishing buildings

If you’ve ever been to Japan, heck, seen pictures of Japan, you’ll know that it can be pretty crowded over there. There can be a ridiculous amount of people in very small areas. With a city so densely populated, what do you do when over 100 skyscrapers have to be demolished in the next 10 years? It looks like Japan’s got it covered.

Taisei Corp. has spent a year and half developing a revolutionary way of demolishing buildings in the most ecological way possible. They’re calling it the Taisei Ecological Reproduction System, or Tecorep for short. The concept behind the method is using the roof of the building as a sort of hat that creates an enclosed space for deconstruction. Temporary columns hold up the roof and are lowered by jacks as floors are removed.

“It’s kind of like having a disassembly factory on top of the building and putting a big hat there, and then the building shrinks from the top,” said a representative of the company. Not only is it safer for workers but it reduces noise by over 25%, cuts dust by as much as 90%, and is more energy efficient.

For a closer look at how it’s done, check out the video below:

    “I was hoping to see more detail as to how they accomplished this, but such is life…”
    @Mike:

    The problem could be someone finding a way of outsourcing it to the Chinese for a fraction of the cost, and tenfold the pollution.

    @Mike: That would depend on what you define as eco-friendly. Due to lack of stringent standards explicitly defining what can be regarded as ecologically friendly, keep in mind companies often take part in ‘green washing’ — claims of something being environmentally friendly when other people or organizations may not consider it to be. It is all a mater of perspective.

    @Mike: Whe I first saw the photos at the top, I thought that the ‘cap’ was part of the building. I thought it looked OK, so perhaps they could use the cap for the construction part and when at required height, incorporate it into the building. Then it would be ready for the time when the building has to come down.
    It might help construction, because ‘floors’ could be made weather proof quicker allowing fitting out and possibly occupation sooner.
