GAI's studies and permitting advance small, single-site projects, as well as larger regional efforts, including infrastructure rehabilitation, new power and gas transmission lines, and the redevelopment of brownfields. Our precise and detailed environmental studies in the initial planning stages keep permitting, planning, and construction on schedule.

Our integrated GIS databases streamline the National Environmental Policy Act (NEPA) process through large-volume data sharing that optimizes the regulatory agency review process. Our environmental professionals work extensively with regulatory agencies at the federal, state, and local levels, and are experienced in acquiring expedited, cost-saving FERC certifications, and environmental and air quality permitting for all types of projects.
