Our Principals and Associates have in depth, operational and hands on expertise, in a broad spectrum of Industries – specializing in Intellectual Property, Safety Regulations, OSHA and Accident Reconstruction. Since 1983, most of our more than 600 Industrial Cases have settled OUT OF COURT – as Experts for Insurers, Defense and Plaintiff Attorneys.

Areas of expertise include natural gas, petroleum, oil & gas production, petrochemical, chemical plants, refineries, power stations, co-generation, pulp & paper, logging & forestry, lumber & wood products, food manufacturing, plastics, industrial & construction equipment, machine & tool design, packaging, materials handling, trucking, warehousing, and industrial construction. Available worldwide for plaintiff and defense cases.


To assist our clients SETTLE their Industrial Cases OUT OF COURT, which significantly reduces the time and cost of extensive litigation.


By hiring an Expert Witness early in a case, with specific industrial experience, you will gain valuable insight about the circumstances – regardless of which side you represent. You will know:
1. What and where poignant plant or supplier documents should exist.
2. What to look for and request to see during a site inspection.
3. What is inside the plant, including processes and equipment.
4. How to interpret data, and spot misinterpretation.
5. Who to depose, what to ask, and where to probe.
6. How they operate, and how their competition operates.
7. What other safeguards were available, but missing.
8. When a Model can demonstrate the circumstances better than words.

A Causey Engineering Expert Witness, trained in Forensic and Investigative Services, can present case circumstances and specific industry standards and regulations, by combining them into an understandable portrait of the case – that will withstand a Daubert Challenge.


Causey Engineering has been providing Expert Witness, Forensic Engineering, Investigation, and Litigation Support services NATIONWIDE since 1983. We specialize in Industrial and Construction Safety, to either plaintiff or defense council – where we have in-depth expertise.

Our experts are professionals with engineering, operational, and management experience in their specialized industry.

Our firm purposefully restricts itself to inter-related industries. This avoids being spread too thin over the complete spectrum of industries. Many regulations and standards that apply to industrial cases are developed by and for a specific industry. A comprehensive understanding of the specific industry is essential in order to block assertions from a hired generalist.

When new Experts become associated with Causey Engineering LLC, they are trained and mentored by Causey, in accordance with the highest standards of the Expert Witnessing profession. They learn the process and requirements to apply their knowledge and assist their client, whether it is on the plaintiff or defense council.

Often, show and tell is much more effective than words. Models can be persuasive. Accordingly, Causey Engineering can design and build relatively inexpensive machine models or components. Historically, medical litigation has had more experience with models. Industrial modeling is considerably simpler and inexpensive compared to medical models. Our extensive experience in modeling frequently results in settlements during Mediation and Deposition.
