d. Seismic Use Groups. Examples of occupancy types or functions in the various Seismic
Use Groups are indicated in Table 1-1. Buildings with multiple occupancies should be
categorized according to the most important occupancy, unless the portion of the building that
houses the most important occupancy can be shown to satisfy all of the requirements for that
e. Structural scores and modifiers. This is the most important portion of the review form.
The lateral load system data recorded from the drawings and the confirming data observed in
the site visit are tempered with the engineering judgment of the engineer to develop a relative
score reflecting the seismic vulnerability of the building. For each building type, this portion of
