Ulteig Fire & Explosion Investigation Services
Fire investigation — sometimes referred to as origin and cause investigation — is the analysis of fire-related
incidents. After the fire is extinguished, the origin and cause of the fire or explosion must be determined.
Investigations of such incidents require a systematic approach and knowledge of fire science.
Ulteig’s fire and explosion investigation team consists of a coordinated group of experienced experts who
are prepared to investigate fire-related losses. Our experts provide timely and accurate services to meet the
needs of our clients.
In litigation, the credibility of the experts is often the deciding factor. In large, complicated losses, multiple
disciplines are often needed to gather and document evidence. Ulteig’s staff includes registered electrical,
structural, mechanical, civil, and fire protection engineers, as well as certified fire investigators.
Whether it is a small loss or a petrochemical plant, Ulteig is at the top of its field in fire sciences. We are
not owned by or associated with an interested party, such as an adjusting company or a law firm; our
independence eliminates the potential for bias.
When requested to conduct a fire scene examination, our investigators follow the same systematic approach
used for origin and cause investigations. As we gather information concerning the incident, they are mindful
that any investigation may turn into a full litigated case. Therefore, when we process a scene, we make sure
that a hypothesis is developed after all the information at the scene is gathered and proper investigative
techniques have been used.
