Values of α ij ACHIEVEMENT (expressed in %); α ij ADVANCE (expressed in %); and the number of required countermeasures for the four countermeasure levels, the different building classifications, and the different building security ratings. One of the advantages of this process is that it systematically ensures that basic countermeasures in the lower security rating categories are not bypassed when attempting to achieve a higher security rating category. 5 BONUS POINTS At the end of each rating category, there is a provision for awarding bonus points.

It is used in evaluating the adequacy of the security of the building within a particular security level. 0. 0. 0, a lower security status is approached. ) situations for a countermeasure. 4 REQUIRED COUNTERMEASURES Several countermeasures in each level are required. A required countermeasure is an essential countermeasure that must be implemented to pass that level. Required countermeasures do not have assigned weights; thus, they do not contribute to the computations in Eqs. (3-1)–(3-5). However, if the building fails to satisfy any required countermeasure, the building will not pass that level; this makes any computation of a security score irrelevant.
