A demolition system developed by Japan's Taisei Corp., called the Taisei Ecological Reproduction System, or Tecorep, turns demo work into a relatively clean and quiet affair. Work begins at the top -- on the inside of the building -- and as floors and walls are removed, the building becomes less tall. "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," said one Taisei engineer.
