Origin and Cause Investigations

Certified fire investigations delivering scientifically grounded findings for technical insights and effective risk mitigation strategies

Whether determining how a residential fire began or analyzing the cause of a catastrophic industrial explosion, our experts deliver timely, comprehensive analyses to support litigation, recovery planning, and prevention efforts.  

Our consultants meet the qualifications of NFPA 1033 and follow NFPA 921 protocols to ensure scientifically sound, court-admissible results. Many hold certifications through IAAI and NAFI and have experience offering expert witness testimony.  

Leveraging a multidisciplinary approach, we integrate civil, structural, chemical, and electrical engineering to develop a holistic view of each case. Fire investigations are enhanced by insights from related disciplines such as thermal sciences and building sciences. This comprehensive expertise allows our team to identify complex, interconnected causes and effects, from material behavior to code compliance. 

We serve a wide array of clients including law firms, insurance carriers, manufacturers, government agencies, and utility companies. These clients rely on our blend of scientific rigor and practical problem-solving to clarify liability, assess damages, and support claim resolution or litigation strategy.
