The realization of vibration studies in the environment are of course necessary to respect the regulations to carry out your projects, but they also constitute a crucial factor of prevention for the health and for the structure of the buildings.
Indeed, construction and demolition work can affect the structural integrity of surrounding buildings. The risks are even higher if these are already degraded (cracks, flaking, subsidence, etc.) because the emission of vibrations risks aggravating the already existing degradations. In Quebec, the specifications for construction projects near residences indicate that vibrations must remain below the threshold of 8 mm/s for buildings in good condition and 3 mm/s for buildings that are already degraded, very old or heritage buildings.
In addition, inhabitants of buildings subject to regular vibrations, near a railway for example, risk being affected in the peace of their sleep and developing related diseases (increased body mass index, overweight, cardiovascular diseases, impairment of cognitive functions, etc.). Vibrations can also be harmful in certain sensitive buildings such as hospitals or laboratories for the operation of equipment very sensitive to vibrations (MRI, electronic microscopes, measuring devices, etc.).
It is therefore crucial to carry out impact studies and vibration monitoring for projects including sources of vibration or sensitive buildings and to comply with the regulations in place.
The @atelier7hz teams are experts in these areas and will assist you in controlling any vibration risk.
