Litigation Support

SPC Engineering provides expert witness services in the fields of geotechnical, civil, and environmental engineering, and represents Plaintiffs, defendants, and third-party defendants in civil litigation matters. We have provided expert witness services in over 500 civil litigation cases, and regularly attend Mediations, Arbitrations, and provide expert witness testimony in deposition and trial.



Professional Experience

Geotechnical issues that are typically evaluated are:

  • Subsidence
  • Expansive soils
  • Corrosive soils
  • Retaining wall failures
  • Slope movement
  • Construction vibrations
  • Earthquake damage
  • Liquefaction


Civil engineering issues are related to determining concrete quality, design and performance, drainage and water intrusion, and asphalt pavement design and performance. Some of these issues include:

  • Concrete cracking
  • Concrete corrosion
  • Efflorescence
  • Sulfate attack
  • Reactive aggregate
  • Pavement distress
  • Drainage
  • Water intrusion
  • Analyses of water consumption records
  • Analyses of rainfall records
  • Surveying



Failure Analyses

In addition to geotechnical and civil, our expertise in forensic engineering includes:

  • Recognition, documentation, and evaluation of structural damage (distress)
  • Damage causation
  • Timing of damage occurrence
  • Determining likelihood of on-going civil/geotechnical/geological influences
  • Evaluating site performance and potential future problems
  • Investigating design/construction-related defects
  • Monitoring movement of soils and foundations
  • Alternative mitigation designs and recommended options for a best-fit solution
