II. NOISE AND VIBRATION

Vibration

On road construction, impact pile-driving may be used to establish a base for foundations.  These operations can give rise to high levels of ground vibrations.  The magnitude of the nuisance created by vibrations depends on the nature of soils transmitting the vibration and the distance to the nearest building.

Objective: To ensure nuisance from noise and vibration does not occur.

Suggested Measures:

• Fit and maintain appropriate mufflers on earth-moving and other vehicles on the site.

• Enclose noisy equipment.

• Provide noise attenuation screens, where appropriate.

• Where an activity is likely to cause a noise nuisance to nearby residents, restrict operating hours to between 7 am and 6 pm weekdays and 7 am to 1 pm Saturday, except where, for practical reasons, the activity is unavoidable.

• Noise should not be above background levels inside any adjacent residence between 10 pm and 7 am.

• Advise local residents when unavoidable out-of-hours work will occur.

• Schedule deliveries to the site so that disruption to local amenity and traffic are minimized.

• Conduct a study on the impact of ground vibration from construction activities where these operations occur within 150 feet of a building and take appropriate action.

• Minimize air vibrations.
