Geotechnical Consulting Services

Peterson Geotechnical Group specializes in forensic geotechnical evaluations. Typically, this includes studying and diagnosing the cause of movement that has led to cracks, separations, and other types of distress in relatively newer buildings. Our evaluations typically culminate with written reports of our findings, opinions, and repair recommendations for the project.

The application of forensic evaluations can apply to a wide variety of projects, including:

  • Providing expert witness testimony for litigated matters and ROC complaints
  • Customer service issues for home builders, developers, general and sub-contractors
  • Independent evaluations for insurance companies and insurance adjusters
  • Surety evaluations for insurance and bonding companies
  • Forensic construction engineering, analysis and consulting
  • Construction defects analysis
  • Foundation repair analysis and recommendations
  • Drainage surveys
  • Soil sampling and analysis to address expansive soil problems and soil stabilization issues

Our forensic evaluations include studying and diagnosing the cause of:

  • Cracks and separations in residential and commercial construction. The majority of the homes we evaluate are relatively newer construction; however, some of the structures that we evaluate are in excess of 50 years and have suddenly developed cracks.
