Forensic Engineering

A significant portion of SPC Geotechnical, Inc.'s consulting services lies in forensic civil and geotechnical engineering, as well as providing expert witness testimony. Forensic engineering focuses on exploring and identifying the mechanisms that have caused foundation failure, earth and slope movement, or unexpected performance of an engineering design. Professionals at SPC Geotechnical, Inc. have been working on forensic cases for 30 years, assisting clients with unmatched expertise in both civil and geotechnical engineering.


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
