Engineering Geology Services

WKA’s engineering geology unit evolved through the process of tailoring our skills to the needs of our clients. Engineering geologists apply their scientific knowledge and experience for identification and mitigation of fault rupture, liquefaction, landslides and other geologic hazard conditions that must be factored into the planning, design, construction and maintenance of civil engineering structures.

Our Geotechnical services include:

  • geologic mapping
  • geologic hazards investigations
  • engineering geologic investigations
  • construction geology
  • land use planning
  • Alquist-Priolo earthquake fault investigations
  • site-specific ground motion analysis
  • seismic source characterizations
  • liquefaction evaluations
  • landslide investigations and mitigation
  • rock and soil slope stability investigations
  • instrumentation installation and analysis
  • seismic refraction surveys – rippability studies and groundwater studies
  • quarry evaluations and reserve estimates
  • third-party peer reviews
  • emergency response
  • forensic engineering geology investigations
  • litigation support and expert witness services
  • percolation testing
  • dispute resolution
  • FERC Part 12D support
