Recently, there was a video on Yahoo news showing an 80-year-old bridge being demolished. Using explosives, from start to finish took less than 30 seconds. Meanwhile, in Noborito, close to the main traffic bridge running over the Tamagawa river, along my regular cycling route, was an old factory building also being demolished. From start to finish, it took over 30 days. This is fairly typical for a project like this in Japan.
About day 3. When I first rode by the site, I didn't have my camera. There was just a single gash in the front wall where the shovel had started cutting from the top. The next day, the weather wasn't good so I didn't ride. He'd made a lot of progress in only 2 days.
About day 10. Weather stayed fairly crappy for about a week, so I wasn't able to get out and ride so much.
Day 14. They laid down a bed of gravel. Either this was to move the shovels closer to the roof, or to give the shovels better traction over the bare dirt.
Day 15, they rested. Actually, this was taken on Christmas weekend. Christmas itself isn't a holiday here, but things like construction companies do shut down for the 2 weeks leading up to the end of the year, and the first few days of the new year. Below, the cranes are in "sleep mode" during the holiday period.
Day 26. It's about Jan. 8 or 9 now, and the destruction has started up again.
Day 27. With the big shovel up and running on its own, things are zipping by pretty quickly.
The other shovels are just waiting their turns again. They're so cute when they're sleeping.
Day 30. Now it's a matter of clean up and pulling the bigger chunks out to be placed in the trucks separately.
Day 34. Finally, time to remove the gravel bed.
