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 projects must adhere to specific requirements set by towns and cities in order to ensure that city planning benefits everyone. Having concrete data to demonstrate compliance with these regulations provides reassurance to all stakeholders involved in the construction and redevelopment of our communities.

Our Pre-Construction Surveys include detailed video and photographic documentation. We meticulously record the existing conditions to accurately determine if construction activities are responsible for any damage. We also maintain ongoing monitoring throughout the construction process to minimize the potential for damage.

Why We Are The Best 

For over two decades, we have proudly upheld our reputation as a trusted provider of precise analysis, adhering to the highest standards and utilizing proven scientific practices in the fields of construction monitoring and seismology.

Our high-definition video inspections conducted before blasting or construction, along with state-of-the-art vibration monitoring services, enable us to swiftly address damage claims. We expedite the process of getting your operations back on track and take care of the complex task of communicating with nearby stakeholders."
