Biography

Dave was introduced to engineering while pursuing an Airframe & Powerplant maintenance degree in university. A love for the details of engineering led to completing his Master's degree in Mechanical Engineering. Dave began his engineering career as a consultant for the power, oil, and gas industries. Expertise developed during this time includes fracture mechanics, welding residual stress analysis, ASME boiler and pressure vessel assessments, API 579/ASME fitness for service assessments, high energy piping design and analysis, and finite element analyses of various types. Discovering a love for the puzzles provided by forensic engineering, Dave continued on to provide consultation in the areas of root cause investigation of mechanical system and component failures. His services include evaluating incidents involving residential, commercial and industrial systems, fire and explosion investigation, product design analysis, damage evaluation, and assessment. Dave has actively consulted for insurance companies, private companies, legal clients, and individuals. Living near San Francisco, California, he can provide resolution for engineering questions throughout California and the contiguous States, Hawaii, and Alberta, Canada.
