Our dam-related services include stability, seepage, and piping analysis; instrumentation engineering and monitoring; failure mode effect analysis and risk assessment; safety review and inspection; engineering design; and construction management and inspection.

Geosyntec’s integrated services bridge the gaps between geotechnical characterization and analysis, structural design, and construction. Our staff is highly experienced in performing site characterization studies in all types of geologic environments and providing traditional geotechnical analysis supplemented with advanced state-of-the-practice numerical modeling to analyze complex loading conditions and soil-structure interaction. Geosyntec performs detailed geostructural design services for a wide range of specialty geotechnical applications including stone columns, rigid inclusions, temporary and permanent retaining walls, soil and rock anchors, and work platforms for specialized construction for construction and remediation of embankment and concrete dams.

Our team has played a leading role in the application of state-of-the-art analyses and seismically induced ground deformation assessments (e.g., liquefaction) evaluations and has spearheaded designing economical structures that safely resist the loads caused by earthquakes. We conduct deterministic and probabilistic seismic hazard analyses, ground motions evaluations, site response analyses, and seismic retrofit support services.

Geosyntec is highly experienced in the use of both standards-based deterministic and risk-based probabilistic evaluations of earthen dams and levees, concrete dams, spillways, outlet works, and other ancillary structures using state of the practice modeling and analytical methodologies. We facilitate risk-informed-decision making (RIDM) by performing quantitative and semi-quantitative risk assessments (QRA and SQRA), developing and implementing risk reduction measures, consequence and hazard potential evaluations, and emergency action planning and exercises.
