Geotechnical Engineering

Our Geotechnical Engineering department is the cornerstone of Wallace-Kuhl & Associates. Since 1984, our geotechnical engineers have evaluated subsurface conditions and produced critically important analytical information for thousands of projects - information that is factored into the design of a project before construction of a foundation, slope grading, or other ground modifications begin. As a result, our geotechnical data library is comprehensive.

Our Geotechnical Engineering services include:

  • Design-Level Geotechnical Engineering Investigations
  • Geotechnical/Geologic Engineering
  • Underground Utility Excavation Support
  • Trenchless Construction Methods
  • Pavement Analysis and Design
  • Bridge Preliminary Foundation Reports
  • Bridge Foundation Reports
  • Slope and Embankment Stability Studies
  • Materials Reports
  • Seepage Studies
  • Seismic Surveys
  • Distressed Structure Investigations
  • Pile Load Test and Driving Observations
  • CIDH Pile Construction Observations
  • Site-Specific Earthquake Ground Response Analyses
  • Foundation Investigations
  • Bedrock Excavation and Rippability Studies
  • Geotechnical Engineering Laboratory Services
  • Geotechnical Baseline Reports

Engineering Geology

Our Engineering Geology department evolved through the process of tailoring our skills to the needs of our clients. Engineering geologists apply their scientific knowledge and experience for the 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 Engineering Geology 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
  • Aerial Photo Interpretation
