What is Root Cause Failure Analysis?
Root Cause Failure Analysis (RCFA) is a structured investigative process used to determine the underlying cause of engineering failures.
In forensic engineering, RCFA is essential for identifying why a component, system, or structure failed—and for preventing similar failures in the future. At Gilmore Engineers, RCFA is a key part of our forensic investigations, helping clients resolve technical disputes, improve designs, and enhance operational safety.
Why is RCFA Critical in Forensic Engineering?
RCFA provides these four key benefits to companies and the legal system:
- Accurate failure diagnosis
- Evidence for legal and insurance claims
- Insights for design and process improvements
- Enhanced safety and reliability
Whether it’s a machinery breakdown, structural collapse, or product defect, RCFA helps determine the true cause – not just the symptoms. In this blog, we’ll help you understand why and how we use RCFA for forensic engineering.
What is Gilmore Engineers’ RCFA Methodology?
Our forensic engineering team follows a proven, data-driven approach:
1. Initial Failure Assessment
We begin by reviewing design documents, operational history, and maintenance records to understand the context of the failure.
2. Site Inspection and Evidence Collection
Our engineers conduct detailed inspections, collect physical evidence, and document the failure using high-resolution photography and technical measurements.
3. Engineering Analysis and Simulation
We use advanced tools and techniques such as:
- Finite Element Analysis (FEA)
- Vibration and stress testing
- Material property analysis
- Thermal imaging
4. Root Cause Identification
Using methods like the 5 Whys, Fault Tree Analysis, and Failure Mode and Effects Analysis (FMEA), we isolate the root cause – whether it’s material fatigue, design flaws, human error, or environmental stress.
5. Reporting and Recommendations
Our findings are presented in a detailed forensic engineering report, often used in court proceedings, insurance claims, and technical reviews.

Frequently Asked Questions
It’s the fundamental, underlying cause of a failure that, if corrected, would prevent the incident from occurring again.
Yes, complex failures often stem from a combination of systemic issues, rather than one single cause.
They use evidence-based approaches, such as forming and testing multiple, alternative hypotheses, to prevent premature, faulty conclusions.
It’s crucial to preserve the scene, take photographic evidence before moving parts, and use ‘bag-and-tag’ methods to catalogue, secure, and transport components to a controlled environment. Forensic engineers should be contacted as soon as possible to aid in their investigation.
