Engineering Geology

Integration and application of earth sciences into the engineering, design and construction process is vital to every project in the built environment. With over 25 years of experience in California we are technically well versed to evaluate and address potential geologic and seismic hazards that affect your projects.


Engineering Geology

  • Geologic Mapping
  • Geophysics
  • Economic Geology
  • Aerial Photograph Interpretation
  • Development Feasibility Studies
  • Geologic Hazard Evaluations
  • Landslide Evaluation
  • Subsurface Exploration/Fault Trenching
  • Earthquake Fault Evaluation
  • Groundwater Control/Dewatering

Our geologic professionals have been involved in mitigation of geologic hazards assessment, induced subsidence mitigation, hillside erosion control, flood assessment, wave runup analysis, and coastal hazards mitigation.
