Count on us to solve your most complex geotechnical, dam, or environmental engineering challenge. Our mission is your success.
With more than 100 years of experience in subsurface conditions, our specialists have the in-depth knowledge and expertise to excel on the most challenging geotechnical assignments. We provide innovative solutions for foundations, underground construction, earth structures, groundwater resources, and marginal building sites. Our geotechnical engineers and geologists specialize in landslides, sinkholes, mine subsidence, seepage, expansive soils, and seismic activity. We’ve completed more than 1,000 subsurface and geophysical projects across the U.S.–from small-scale projects to large, complex dams, highways, bridges, and underground structures.
Aging infrastructure, climate change, extreme weather events, and rising sea levels present challenges to our communities. We help our clients stay prepared with innovative, cost-effective designs to renew their existing dams or bring new dams online to meet current needs, plan for the future, and keep communities safe. Our designs serve our clients’ needs for water supply, flood damage reduction, navigation, and recreation, to sustain communities. Since our founding more than 100 years ago, our Dams and Hydraulics team has designed more than 100 new dams, modified over 250 dams and 50 levee systems, and evaluated the safety of more than 500 dams.
Our environmental expertise spans a wide range of environmental, site assessment, regulatory compliance, and remediation services. With experience in federal, state, and local regulations, we provide permitting and compliance support. Our cost-effective remedial services help clients solve existing remediation needs and identify potential hazards before they impact operations and result in adverse environmental conditions. Our full complement of services includes everything from initial site investigation to final remedial action implementation and compliance audits.
