In 1958, GAI was a 6-man engineering design firm with a vision to provide innovative applied engineering in foundation studies and soil mechanics. By the '80s we were designing major highways and bridges, discovering precious historic artifacts, and studying the effects of abandoned mines on the environment. Today we have 600+ professionals dedicated to projects in energy, environmental, transportation, land development, industry and government... 50 years of transforming ideas into reality.
