Earth Structures

Gannett Fleming utilizes the latest in computer-aided analysis and laboratory testing to determine stability, seepage paths and construction materials for levees, dams, dikes and other earth structures. We have designed tunnels and underground structures in many different geologic conditions including soft clays, rock, sand and mixed faces. Our portfolio includes rural mountainous areas as well as urban areas where underpinning and existing structure protection are critical. Furthermore, Gannett Fleming is a leader in the design of roller compacted concrete dams.
