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.
