Construction activities including pile driving, blasting, and heavy equipment operation generate vibration that can damage nearby structures. Vibration limits protect buildings from damage. Peak particle velocity (PPV) measured in inches per second indicates vibration intensity. Historic structures are more sensitive to vibration than modern structures. Vibration monitoring verifies that activities comply with limits. Seismographs placed on affected structures record vibration. Baseline measurements before construction establish normal vibration levels. During construction, vibration is monitored continuously. Exceedances of limits trigger work modifications or stoppages. Vibration reduction methods include distance (perform activities far from sensitive structures) and damping (reduce vibration at the source). Cushioning materials reduce impact vibration from pile driving. Helical piles instead of impact-driven piles eliminate vibration. Explosive charges can be reduced to minimize vibration from blasting. Vibration velocity can be measured at the source and adjusted. Pre-construction surveys document condition of nearby structures. Photographic documentation shows cracks and condition. If vibration causes damage, the condition is compared to baseline. Notification of property owners before vibration-generating work is professional courtesy. Control measures may be coordinated with neighbors. Insurance coverage for vibration-related damage is important.
