Geotechnical engineering is the portion of civil engineering that deals with all aspects of the theory and practice of soil mechanics. Geotechnical Engineers in the U.S. Army Corps of Engineers are integral to project activities such as materials property determination, foundation design, slope stability evaluation and remediation, design of dewatering, seepage, and uplift control systems, and project performance monitoring and instrumentation. Geotechnical Engineers ensure that the ground and soil conditions are thoroughly understood and properly managed to support safe and effective construction and engineering solutions.
