Bridge and Overpass Structures Print E-mail

For over 25 years, GAI's experienced, award-winning staff has designed, inspected, and rehabilitated all types of bridge and overpass structures. Our understanding of safety standards, construction processes, and material and workmanship practices results in long-term returns on infrastructure investments.

GAI’s certified bridge inspectors identify conditions that may impair safe operation or useful life expectancy of a bridge, and develop repair recommendations. Valuable in-house capabilities provide all support services for structure projects, such as hydraulic analyses, geotechnical engineering, and environmental and archaeological investigations.
