What is a forensic engineering expert witness?

The background of a forensic engineering expert witness will vary greatly depending on the product and technology involved in a case. In general, a forensic engineering expert witness has an engineering discipline degree (i.e., mechanical engineering, materials engineering, civil engineering, structural engineering, or electrical engineering), along with extensive experience in forensic engineering, accident reconstruction, and/or laboratory testing. The chosen expert may be a member of an industry association, such as the National Academy of Forensic Engineers (NAFE).

What types of cases require a forensic engineering expert witness?

The primary purpose of a forensic engineering investigation is to locate the cause of a failure, assist in an accident investigation, or to investigate intellectual property infringement claims. Cahn Litigation Services most often works on cases requiring forensic engineering expertise that revolve around product liability and patent infringement matters.

Forensic engineering expert witness case examples

Representing the plaintiff or defendant, when the need for a forensic investigation expert arises, top litigation firms call on Cahn Litigation Services. Whether the case involves:

• electrocution accident,
• geotechnical engineering,
• construction management liability analysis for insurance companies,
• NFPA’s Life Safety Code,
• forensic analysis of a control system failure,
• fire investigation by a Certified Fire & Explosion Investigator (CFEI),
• traffic accident reconstruction,
• root cause of a building systems’ HVAC corrosion issues,
• safety engineering,
• forensic electrical engineering methodology,
• construction defect issues, or
• any type of matter requiring forensic engineering expertise.

What litigation support work might a forensic engineering expert witness be expected to perform?

Forensic engineering services in support of litigation could include product testing and failure analyses, reverse engineering, research and authoring expert reports, arbitrations, depositions, providing expert opinions, and/or courtroom testimony. In addition, a law firm may request a forensic engineering expert for pre-litigation consulting services. In a high-profile case, or litigation involving a significant financial stake, a law firm may require a forensic expert with prior expert witness testimony experience.

Cahn Litigation Services has the experience required to turn a search for a forensic engineering expert witness around quickly, providing the right balance of expertise and testimony experience.
