Mr. Wittasek specializes in fire protection engineering, building and fire codes, accessibility, failure analysis, and origin and cause determination. He has more than 15 years of experience providing fire protection engineering codes consulting and failure analysis. Mr. Wittasek has extensive experience addressing issues related to combustible and flammable liquids, explosions, fire alarm and detection systems, fire resistive compartmentation and materials, fire department access and water supplies, fire modeling, fire testing of construction assemblies, fire suppression systems, flame spread analysis, hazardous materials classification and mitigation, means of egress, smoke movement and smoke control. Mr. Wittasek brings a detailed and pragmatic approach to his clients that reflect his knowledge of how fire and life safety principles and the use of the scientific method relate to building and fire codes, safety standards, fire protection systems failure analysis, and forensic investigation. Having served as a fire fighter, fire science research professional, consultant in the A/E industry, and educator, he is uniquely positioned to contribute both proactively and reactively. He has investigated failures involving flues and chimneys, heating appliances, fire suppression systems (sprinkler and foam systems), fire alarm systems, and smoke management systems. Mr. Wittasek has been involved with the development of fire and life safety strategies and engineered (performance based) approaches for well over 200 facilities in the following sectors:
- Assembly facilities (arenas, casinos, stadiums, and theaters)
- Cultural resource properties (museums, libraries, and performing arts venues)
- Critical facilities (data centers, scientific & engineering laboratories, communications)
- Healthcare facilities (hospitals, medical research facilities and medical office buildings)
- High-rise buildings containing commercial, hotels and residential condominiums
- Historical buildings undergoing restoration, renovation or adaptive re-use
- Transit facilities (rail stations, tunnels and airport terminals)
He has worked extensively throughout North America, Central America, China, Europe, the Middle East, and Russia utilizing local and internationally adopted codes and standards including those published by the American Society of Testing and Materials (ASTM), International Codes Council (ICC), National Fire Protection Association (NFPA), Office of Statewide Health Planning and Development (OSHPD), Joint Commission (JCAHO), American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), American Society of Testing and Materials (ASTM), Factory Mutual (FM) and Underwriters Laboratories (UL).
