Instrumentation Services


Geotechnical instrumentation may be used to assist project design teams with early characterization of in-situ site conditions, as well as verification of design assumptions. Instrumentation during the construction-phase of projects may be used to monitor the effects of construction on the subsoils, and real-time stability and behavior of the subsoil mass and groundwater.  Other applications include long-term performance monitoring and risk management.

Instrumentation and monitoring services are required where there is a possibility of a structure’s stability or safety being compromised, or where factors of safety are considered marginal.  Accurate and repeatable data is crucial to the success of projects.  Our teams are experienced in developing, installing and executing site-specific instrumentation and monitoring solutions.


Thompson Engineering maintains a staff of experienced engineers, instrumentation technicians and surveyors, all focused on delivering a quality product on schedule.  We utilize only the highest-quality, precision equipment manufactured by experienced leaders in the field, such as Geokon.

Our in-house teams are qualified and safety trained. They maintain TWIC, OSHA 40-hr, CSX rail safe training, and other related credentials.
