HSI Vibration Monitoring NY NYC NJ CT PA MA


Thank you to our clients!

HSI ensures our clients are in regulatory compliance and provides the Third Party you need for positive public relations.

Documentation Protects Everyone 

All construction must meet a set of requirements decided by towns and cities to ensure that city planning works for everyone. Having hard data to prove compliance with these laws is here to provide peace of mind for everyone involved as we build and rebuild our communities.

Our Pre Construction surveys provide meticulous video and photographic documentation. We document pre-existing conditions to clearly ascertain if construction activities are the cause of any damage. Our ongoing monitoring follows the survey to limit the possibility of damage during construction. 

Why We Are The Best 

For more than 20 years, we have treasured our reputation for providing the Northeast with exact analysis, highest standards and proven scientific practices in seismology and construction monitoring.
