We’re proud to share that GLA has once again earned a spot on Engineering News-Record’s prestigious Top 225 International Design Firms list!

In 2024, nearly 15% of our total revenue came from international projects spanning Peru, Bulgaria, Turkey, and Canada—with Peru leading the way. Our full-service Lima office is home to a multidisciplinary team of civil and geotechnical engineers, geologists, hydrogeologists, hydrology and hydraulics experts, and environmental engineers.

A key driver of our global success? Enhanced Metal Recovery—GLA’s innovative injection leaching process that helps mining clients recover tens of thousands of additional ounces of ore. This breakthrough technology continues to set us apart in the international mining sector.
