Vibration monitoring systems are capable of recording and storing vibration data generated by construction activities. Two of the most commonly monitored construction activities are blasting and pile driving. Through the years blasting in urban areas has become less of a widely used method though occasionally it is used under careful supervision. Pile driving and drilling is utilized on nearly every job requiring "support of excavation." These projects are typically located in dense areas and require procedures to monitor the impact on adjacent structures. In this instance, a vibration monitor can be used to determine the likelihood of damaging an adjacent structure.
