Video – Stealth demolition…

Inside the incredible shrinking Tokyo hotel.

Back at the beginning of the year, we brought you footage of a new demolition method being pioneered in Japan that allowed engineers to bring down a 456-foot tall hotel building, all the while keeping the roof intact.

Now, thanks to one of our readers, we can bring you an insight into just how the work was carried out, together with a look at a 40-storey “bottom-up” demolition in the same city. If you’re into the engineering side of the business, you will find this fascinating.
