If you build a building or tear down an old building, you need to be concerned about the neighborhood more than you think.
If people who live near the construction site are angry with the contractor for some reason,
you might not be able to continue to build or the working time might be restricted.
Contractors always make an effort to meet the nearby residents before they being to build..
The numbers in the photo shows the noise level and vibration level in the construction site.
People walking around the place can confirm the noise level and feel that the contractor seems to do well.
When the number is less than the legal limit, the contractor can say that they are respecting the neighborhood.
However, some people might think the sound is too loud even if the number is low.
Anyway the field superintendent needs to be wary of the noize level and complaints in the neighborhood.
Life in Kawagoe 
very interesting practice…
Thanks.I think so.
That is a wise decision to display the decibel level sign: I like the idea…. It is a smart reminder to the contractor to keep noise in check. Wish we had more of them in big cities… 🙂
Thanks.The contractor has to think about a lot of things..
Wish we have them here. 😦
I hope you will live in calm place.
I wish it was the same here !
I hope the contractor in France use it. 🙂
Wow, what a cool idea! You would never see that here, too bad.
The contractor could think of the idea maybe because people living in the neighborhood was angry. 🙂
The numbers in the photo shows the noise level – never saw this, but it is very good idea – not for architecture, but for some disco, rock or karaoke music stage shows!
Interesting idea.People living around disco and karaoke are also annoyed in a noise.
家を建てる時、隣接する敷地、建物への影響を考えないといけない事 境界、日当たり、窓、換気扇の位置 雨水・・・ まだまだ山のようにありそうですね。 きっと考え出したら、山の中の一軒家で暮らしたくなるでしょうね。
やはり、狭い場所に密集かつ高層に建てるといろいろな問題が起きるようです。。
都会から離れてよかったと思います。。
Very good idea. It is not used in South Africa.
You had better use this idea in South Africa for the first time. 🙂
during the FIFA soccer world cup in Africa beneath Voovoozeelas the noise level tool for sure would have been exploded!
I think so.During the world cup even players could not hear their teammate’s voice.
Wow. Very interesting to show the noise levels at the site. Never see anything like that in America.
I was surprised that all blog friends didn’t see that.I often see that in many places.
I never knew about this too……great idea!
Thanks.That was good to upload this photo. 🙂
I just seems such as thoughtful idea! I wish they had something like that in the US.
Thank you for your comment.I hope that you will also see this idea in the US someday.
I’ve never seen a measurement for decible level at construction sites. What a grand idea! The Japanese are very considerate people.
Thanks a lot.I’m happy to hear that Japanese are considerate people. 🙂
Like everyone else, I must say that I haven’t seen that over here in the States. Very neat idea to consider here though! I like the random photo. 🙂
Thanks much. I didn’t think that this was neat idea. Since the area is small, we need this idea.
I do not see this here in Thailand nor in the Philippines. It is actually a good idea to adapt. Very informative entry!
Thank you for stopping by. I’m glad to hear that. This idea will adapt in different places.
