Bay Area Geotechnical Group

Provides engineering criteria for design or planning purposes by evaluating subsurface conditions. Services span a wide variety of structures including commercial developments, residential subdivisions, mid-rise buildings, landfill facilities, and transportation infrastructure.

• Subsurface Investigations

  Explores soil and groundwater conditions using advanced sampling techniques to establish baseline site criteria.

• Geotechnical Feasibility Studies

  Evaluates preliminary site conditions to identify potential geologic constraints prior to property acquisition or development.

• Seismic and Liquefaction Studies

  Assesses earthquake hazards, ground motion, and the potential for soil liquefaction to support structural design.

• Slope Stability Analysis

  Evaluates landslide risk and natural slope conditions to design safe grading and stabilization measures.

• Seismic Refraction and Rippability Studies

  Determines rock excavatability and subsurface profiling through geophysical refraction methods.

Applies geosciences to civil engineering projects to identify and address geologic hazards. This work ensures that seismic, slope, and soil factors are thoroughly evaluated during site selection, design, and construction.

• Geological Hazard Assessments

  Identifies hazards such as landslides, slope instability, erosion, flooding, and dewatering to guide mitigation efforts.

• Earthquake Fault Studies

  Investigates fault lines and surface rupture hazards near proposed or existing structures.

Helps clients navigate environmental compliance issues by combining technical expertise with a thorough knowledge of regulatory requirements. Studies are designed to follow appropriate ASTM standards to support transactions and site safety.

• Phase I Preliminary Site Assessments

  Conducts historical and records research to identify potential environmental liabilities and recognized environmental conditions.

• Phase II Qualitative Site Assessments

  Performs soil and groundwater sampling to evaluate the presence of hazardous substances.

• Site Remediation and Compliance

  Designs and monitors remediation measures, assists with regulatory permitting, and manages ongoing compliance reporting.

Delivers field quality control, observation, and materials verification to ensure projects are built in accordance with engineered designs and specifications.

• Construction Monitoring

  Observes site grading, foundation installation, and remediation work to verify compliance with geotechnical recommendations.

• Special Inspection Services

  Provides certified inspection for reinforced concrete, structural steel, and other critical structural elements.

• In-House Laboratory Testing

  Operates a certified laboratory facility to perform testing on soil, concrete, and steel samples.
