01Services
How we help
Engineering analysis you can rely on, from the first scene visit to testimony in the courtroom.
Forensic Engineering
We have the tools and the know-how to conduct forensic investigations in our areas of expertise, and our work is peer reviewed at every step of the investigation.
Learn more
Root Cause Analysis
A systematic look at the underlying causes of a failure, not just its symptoms, so the real source of the problem is found and similar problems do not recur.
Learn more
Litigation Support
Admissible reports, testimony at deposition and in the courtroom, and help with discovery requests and deposition strategy.

02Investigations
Electrical investigations we handle
Residential electrical
Fire causation from product and appliance failures, defective workmanship and electromechanical defects, plus damage from lightning and distribution system faults.
Shock, electrocution and arc flash
Workplace electrical safety, OSHA, CFR and NFPA 70E knowledge, combined with hands-on experience in shipyards and other dangerous environments.
Commercial and industrial
Fires and accidents involving industrial equipment, damage classification for insurance adjusters, and equipment condition assessments.
Marine fires
30 years of operating and maintaining boats and a combined 80+ years of experience on Navy shipboard systems.
Vehicles
Automotive fires, lemon law matters, defective workmanship, and design or manufacturing defects in cars, motorcycles, construction and recreational vehicles.
Failure analysis
Experiments, exemplar products and the interpretation of x-ray, CT, SEM and EDS images and data to test each explanation.
03Fire scene examinations
Your expert at the scene, in person or remotely
Every loss is different, so we offer three ways to bring an electrical engineer into a scene or field examination:
- In person: we lead or co-lead the examination and plan the evidence collection. Recommended for large or complex losses.
- Live and virtual: your expert takes part through a smartphone or tablet, which saves the cost and time of travel.
- On call: your expert is available to your on-scene investigator for planned activities, such as testing an electrical system.
See all scene examination options, or the field test equipment we can bring or ship to the scene.
