Vibration control in construction projects

Leave a comment

There are numerous sources of noise and vibration in any construction project, from small hand tools, to large machinery such as drills, pile drivers, excavators and lorries. There are different types of regulations, both national and local, which establish maximum authorised levels to ensure that such noise and vibration does not harm the environment.untitled0

Noise and vibration are two closely related phenomena. Both are the result of an oscillation with a certain frequency. The essential difference lies in the medium through which they propagate.

A high level of prolonged exposure to vibrations triggers short-term health problems (e.g. migraine, difficulty concentrating, dizziness and pain) and eventually long-term physical sequelae (e.g. lumbago, inflammation of cartilage and osteoarthritis).

The experience of NIHON KASETSU in measuring vibrations in very diverse construction projects has led to the development of a simple and effective methodology for recording vibration levels with the eComo monitoring system.

The system allows for the analysis of specific activity during the duration of the project, with threshold values being able to be established remotely and automatic alerts received when these are exceeded.

To control vibrations transmitted outside the work perimeter, in nearby residential areas, for example, the number of sensors and their positions need to be properly determined.

In addition, to measure vibration properly, the vibration sensor, the accelerometer, must be properly supported on a rigid surface and in the same plane as the vibration to capture the movement in the perpendicular axis, so that no other element can cause mechanical interference.
