How I Help Attorneys Win Cases
Dr. Mitchell provides expert witness and litigation consulting services across the full spectrum of structural engineering disputes. Whether you represent plaintiffs in a construction defect action or defendants in a structural failure claim, Dr. Mitchell delivers the rigorous analysis, credible reporting, and clear courtroom testimony that strengthens your case. His 25-year track record includes 150+ completed engagements with zero Daubert exclusions and repeat retention by major construction law firms throughout California, Nevada, Arizona, and Oregon.
All engagements begin with a complimentary conflict check and preliminary case review. Dr. Mitchell accepts both plaintiff and defense appointments. His opinions are driven by engineering science and applicable codes — not advocacy for either side — which is precisely what makes his testimony credible to judges and juries.
Core Service Areas
Construction Defects
Site investigation, document review, causation analysis, and expert reporting for residential and commercial construction defect claims — from foundation failures to framing errors and cladding failures.
Structural Failures
Forensic analysis of collapsed, cracked, or structurally compromised buildings. Root cause determination, responsible party analysis, and expert opinions on engineering standards of care.
Building Code Compliance
Detailed review of applicable building codes at time of construction, code evolution analysis, and standard-of-care opinions for design professionals and general contractors.
Water Intrusion & Moisture Damage
Building science investigation to determine water entry points, migration paths, damage causation, and contractor or design liability in moisture-related claims.
Forensic Analysis & Material Testing
Laboratory and field testing of concrete, steel, wood, and composite materials to characterize failure mechanisms, timeline, and causation for litigation purposes.
Litigation Consulting & Testimony
Full-service litigation support: initial case assessment, expert report preparation, rebuttal opinions, deposition preparation, and clear, credible trial testimony.
Construction Defect Investigations — What I Do
Scope of Investigation
- Initial case assessment and conflict-of-interest check
- Review of construction documents, plans, specifications, and permits
- Site inspection with photographic and measurement documentation
- Material sampling and laboratory testing where indicated
- Analysis of applicable building codes and standards at time of construction
- Causation determination: what failed, why it failed, and who is responsible
- Preparation of detailed written expert report with findings and opinions
- Deposition testimony and trial testimony as required
Retained by plaintiff counsel in a $4.2M construction defect dispute involving a 32-unit condominium complex in the San Francisco Bay Area. Extensive water intrusion had caused structural wood rot in 18 of 32 units. Dr. Mitchell's investigation identified three distinct defect sources: improper flashing at window-to-wall transitions, missing vapor barriers in exterior wall assemblies, and undersized roof drainage designed below applicable code requirements. His report and deposition testimony supported a mediated settlement covering full remediation costs.
Structural Failure Analysis — What I Do
Scope of Investigation
- Emergency site inspection to document conditions before remediation
- Structural load calculation review and independent engineering analysis
- Review of original design drawings and any as-built modifications
- Material testing of failed structural components (concrete cores, steel samples)
- Comparison of as-built conditions to original design intent and applicable codes
- Determination of failure mechanism: design deficiency, construction error, or material failure
- Preparation of cause-and-origin report suitable for use in litigation
Retained by defense counsel in a structural failure claim involving a partial collapse of a parking structure at a mixed-use development in Nevada. The plaintiff alleged design deficiency; Dr. Mitchell's forensic investigation identified undocumented post-construction modifications to structural support columns made by a tenant contractor without permit or engineering review. His analysis reframed the case from design negligence to unauthorized alteration, providing the defense a clear alternative causation theory that was supported by the engineering evidence.
Other Service Areas
- Seismic Design & Earthquake Damage: Analysis of seismic design standards, lateral force compliance, earthquake damage assessment, and pre-existing defect analysis in post-seismic claims.
- Residential Property Disputes: Single-family home construction defects, soil movement and foundation settlement, retaining wall failures.
- Insurance Subrogation: Cause-and-origin investigations for property insurers pursuing subrogation claims against contractors or design professionals.
- Neutral Expert Appointments: Court-appointed neutral expert analysis in disputes requiring an independent engineering assessment.
- Rebuttal Opinions: Review and rebuttal of opposing expert reports in active litigation.
