Capabilities

Geotechnical Engineering

Comprehensive subsurface investigations and engineering analyses to evaluate soil and geologic conditions for civil works and structural foundations.

  • Site Characterization & Engineering Geology

    Evaluating geological hazards, soil conditions, and site parameters to inform structural layout and risk mitigation.

  • Seismic Design & Analysis

    Developing seismic criteria, conducting ground motion evaluations, and performing dynamic soil-structure interaction assessments.

  • Soil-Structure Interaction Analysis

    Evaluating the complex physical response between underground geologic formations and structural elements.

  • Liquefaction Analysis

    Evaluating liquefaction hazards, post-liquefaction settlement, and developing reliable ground-improvement solutions.

  • Field Investigation & Geotechnical Drilling

    Direct site explorations, soil sampling, and standard penetration testing to collect high-fidelity subsurface data.
