As GAI's first and largest office, our Pittsburgh operation began in 1958 with six Carnegie Mellon University graduates providing highly specialized geotechnical and structural engineering services. Today the office is a multi-disciplined engineering operation with a staff of nearly 300 professionals. An award-winning and well-established company in the southwestern Pennsylvania region, GAI's Pittsburgh office continues to grow its business in transportation, energy, land development, environmental, cultural resources, and geotechnical engineering services.
