Since 1958, GAI has helped clients manage the ground materials and geologic processes essential to their facilities and project successes. Our geotechnical engineers and geologists are highly experienced in the principles of engineering geology, soil and rock mechanics, foundation engineering, subsidence, and mine studies.

GAI has some of the most experienced mine fire experts in the private consulting field, making us uniquely qualified to address any aspect of mine fire diagnosis and control. We maintain a certified AASHTO Materials Reference Laboratory (AMRL) and Cement and Concrete Reference Library (CCRL) facility in Pennsylvania, providing solid data and answers for a broad range of geotechnical investigation disciplines.
