"This manual provides guidance for building inspectors, architects and engineers on quickly and effectively determining what, if any, are the risks posed to the building by natural hazards, terrorist attacks and other threats to the building's structural integrity. [...] This rapid visual screening procedure has been developed for use in assessing risk of terrorist attack on standard commercial buildings in urban or semi-urban areas, but it is also intended to be applicable nationwide for all conventional building types. It can be used to identify the level of risk for a single building, or the relative risk among buildings in a portfolio, community, or region as a prioritization tool for further risk management activities. The information gathered as part of this screening procedure can also be used to support and facilitate higher level assessments by expert investigators performing building-specific evaluations of threat, consequences, and vulnerability."
