It is possible to evaluate the comparative level of risk today by the analytical techniques described in the engineering method for building firesafety. The numerical values are, of course, comparative and not absolute. Nevertheless, the engineering method does permit a relative consistency in building analyses because of the structure of the analysis. The method can incorporate new research findings without disruption of the basic framework and structure. If guidelines were prepared for numerical evaluation of the components, collection of statistical data on an ongoing basis, incorporated into a Bayesian updating would eventually produce an absolute level of risk for any building. The current approach is not so much to develop an absolute risk analysis for a building, even though it is possible to do so, but rather to integrate building analysis experiences with research results to develop deterministic equations that eventually can be used for office calculation in engineering practice. These deterministic equations will be subjected to reliability analyses to gain an insight into the important variables and incorporated into the equations to form a basis for a fire design code that is analogous to a structural design code.
