1.1 This practice covers a definitive procedure for rating the serviceability of a building or building-related facility, that is, for ascertaining its capability to perform the functions for which it is designed, used, or required to be used. A separate scale is used for each topic of serviceability. For each topic, a serviceability level is ascertained. Overall serviceability is expressed as a profile of levels (that is, not as a single number), and may be presented as a bar chart.

1.2 This practice is not intended to be used for regulatory purposes.

1.3 This practice can be used to rate the serviceability of a building or building-related facility that has been planned but not yet built, or which is about to be remodelled or rehabilitated, for example, for which single-line drawings and outline specifications have been prepared.
