Geotechnical

The conditions below the ground surface cannot be easily predicted without a thorough subsurface exploration and proper evaluation of the data collected. It is essential that the exploration program be planned based on the local geologic conditions, the potential environmental factors, the geotechnical engineer’s experience, and the intended use of the property.

Our firm provides geotechnical recommendations that result in cost-effective site development and foundation design/construction, and a reduced likelihood of construction delays caused by unforeseen conditions.
