GLA proudly ranks among the Engineering News-Record (ENR) Top 500 Design Firms, thanks to our outstanding engineering services provided both nationally and internationally, as reflected in our 2024 revenue.

Our success is a collective effort of GLA and its wholly owned subsidiaries, including Clear Creek Associates, Daniel B. Stephens & Associates, Geo-Logic Perú, Kunkel Engineering Group, Summit Water Resources, and The MINES Group. Project successes in 2024 included implementation of an innovative heap leach injection process for Enhanced Metal Recovery at a mine in Perú, large landslide mitigation projects in California, and permitting, monitoring, and related technical support for carbon management projects across the United States.  These successes have allowed GLA to continue to grow our California operations, add resources in Illinois and northern Texas, and incorporate Loughlin Water Resources of Park City, Utah into the company.

As an employee-owned, multidisciplinary environmental, civil, and geotechnical engineering consulting firm with over 300 professionals in 29 offices across the U.S. and abroad, we offer diverse geologic, engineering, water, and environmental consulting services for landfills, mines, contaminated sites, municipal projects, natural resources, and water resources.
