Expert Witness

Mechanical and plumbing system deficiencies and failures cause property damage, injuries, and fatalities. I provide forensic investigations to determine the root cause of failures and testify as an expert witness in litigation to ensure disputes are resolved based on sound engineering analysis.

For over 25 years, Mr. Griffith has provided forensic investigations, expert witness services, and litigation support for cases involving HVAC design, plumbing design, pipe failures, plumbing component failures, sprinkler system failures, hot water scalding, water heater failures, gas venting/carbon monoxide poisoning, and gas furnaces. He participates in the development and revision of national fuel gas and plumbing system standards through his involvement with technical committees. Experience includes work related to fuel gas systems, combustion appliance venting, plumbing systems, and domestic hot water system design.

As the principal mechanical engineer at Griffith Engineering & Consulting for over 28 years, my training and experience in designing plumbing, HVAC, and fire sprinkler systems enable me to offer professional opinions on the adequacy of system design, construction, maintenance, and operation.

I provide investigative engineering, consulting, and expert witness services that are thorough, credible, and timely. I strive to perform independent analyses based on factual evidence and the proper application of engineering and scientific principles.

As a licensed professional engineer, I can assist with investigations in the following areas:

Areas of Forensic Practice

  • Carbon monoxide exposure in buildings

  • Fuel gas systems and appliance-related incidents

  • Hot water systems and scald injury investigations

  • Venting and combustion air systems

  • Plumbing and mechanical (HVAC) system failures

  • Building code application and interpretation

 

Engagement Philosophy

Mr. Griffith approaches each assignment with an emphasis on:

  • Technical accuracy

  • Independence and objectivity

  • Clear communication of engineering concepts

  • Adherence to accepted forensic engineering practice

He is retained by both plaintiffs and defendants and does not advocate for outcomes outside the bounds of his engineering opinions.

  • Licensed Professional Engineer with multi-state licensure across the United States.
  •  
  • Board Certified in Forensic Engineering (NAFE).

 

Curriculum Vitae available upon request.
