WAI is one of the leading firms in assessing and quantifying blast risk to structures. The firm was one of the first to transfer probabilistic seismic hazard and risk techniques to the field of blast engineering. Relying on the classical definition of risk, WAI has developed a blast risk quantification procedure that is based on assessing threat occurrence likelihood, evaluating structural vulnerability to the defined threats, and characterizing facility importance. The procedure was successfully used by the Port Authority of New York and New Jersey to prioritize, from a risk standpoint, their portfolio of facilities, and then conduct cost-benefit analysis to rank and select several blast mitigation projects at the various facilities. The procedure is currently being used for other major infrastructure projects, and is being adapted for estimating insured building losses due to blast events for a major US-based property and casualty insurer. |
