Many construction projects require careful monitoring of noise and/or vibration impacts on adjacent communities and structures, to avoid exceeding local regulations or damaging adjacent property.  In addition, underwater construction activities, such as pile-driving in bridge construction, can generate extreme underwater sound levels, which are regulated to protect marine wildlife.  This requires careful monitoring of underwater sound levels, to avoid exceeding regulations.


We own and maintain a full suite of noise and vibration monitoring instruments, capable of both attended and remote operation.  The remote systems can be programmed to monitor noise and vibration levels continuously in real-time and issue exceedance alerts via SMS message and email.  Our construction services can begin at the project planning stage: our engineering staff can develop mitigation strategies to minimize the chance of unacceptable impacts.  Below are some of our noise, vibration and hydroacoustic monitoring projects.
