Several possible levels of analysis are identified, each leading to both quantitative (economic) and subjective (human) risk evaluations. These range from ratings based only on historical design information to application of state-of-the-art inelastic collapse analysis.

Two case histories are described, including application to proposed offshore property acquisitions.
