Pre-construction surveys allow for the determination of a baseline record of preexisting conditions of properties near sites where vibratory work, including excavating, blasting, and pile driving, is to be done. Per ANSI A10.34-2001, pre-construction surveys are required before work can start for the protection of the contractor and the surrounding property’s owners and tenants. Post-construction surveys damage alleged to have been caused from construction.

Vibration and noise monitoring provide necessary feedback for analyzing ground vibration and noise protection and regulatory compliance. Understanding the radiuses of influence from construction activities mitigate claims and litigation. Monitors are set to alert any activity that meets or exceeds a minimum threshold within a predetermined distance from construction. This allows experts to measure movement caused by activity. Data collected show any variations from expected intensities, highlighting unsafe or unexpected activity. Additionally, they provide a record of vibration activity which serves as evidence in the evaluation of damage claims that may arise.
