GAI's cultural resources staff is one of the few groups nationwide providing archaeological and historic architectural services within an engineering and environmental consulting firm.

For more than 35 years, we have successfully guided clients through the Section 106, NEPA, FERC, and environmental permitting processes, and have skillfully managed consultation with Native American tribes and local, state, and federal historic preservation entities. Our cultural resources professionals mobilize across the United States, steadily expanding staff and expertise to provide top-quality service for clients in transportation, mining, gas and electric utilities, private land development, and federal, state, and municipal governments.

Nationally recognized for efficiently meeting the requirements of historic preservation and environmental regulations, GAI’s core team of cultural resources specialists provide innovative services in historic, prehistoric, and urban archaeology, historic preservation and public history, and soils science. From nuclear power plants, electric transmission lines, and natural gas pipelines to military battlefields, and Native American sites, GAI has built a performance record for providing accurate, cost-effective results that serve clients' time-sensitive needs.
