Inspect the outer wall of a high-rise building with a drone First experiment in Japan Nakano-ku, Tokyo March 17, 14:19

With the aging of high-rise buildings becoming an issue, this is a new initiative to promote efficient inspections. In an urban area where populations are concentrated, the first nationwide experiment using a drone to inspect the outer wall of a building was conducted in Nakano-ku, Tokyo.

The experiment was conducted at the Nakano Sun Plaza, a 20-story high-rise building near Nakano Station in Tokyo, by the National Institute of Architects and a private construction company.

In the experiment, a drone with a camera is shot along the wall of a building about 90 meters high to photograph the state of the wall, and it is determined from the image whether there is a crack or paint has been removed. Although more efficient than assembling a scaffold and inspecting directly by workers, flying a drone in a densely populated urban area would have been more risky in the event of a crash and could not proceed.

For this reason, this time, a string of fishing line called a “line” was hung from the roof of the building along the outer wall, and passed through a part of the drone's fuselage to reduce the risk of flight deviation and crash. Construction companies and other companies are aiming for practical use around the fall, as drones can be expected to significantly reduce work costs and time.

"In urban areas, skyscrapers and condominiums are rapidly increasing, and aging is a major issue. I want to spread the use of drone inspections with safety first," said Hiroyuki Miyauchi, a senior researcher at the Building Research Institute. I was
