The Level 1 – PST aims to quickly identify buildings for which the seismic performance can be assessed with reasonable certainty on the basis of four key criteria, namely: (1) seismicity; (2) benchmark NBC edition; (3) remaining occupancy time; and (4) consequences of failure. The Level 1 – PST also identifies special conditions that immediately trigger further seismic risk assessment. These conditions are (1) unknown model building type, (2) federal heritage designation, (3), change of occupancy results in increase of structural loads, (4) consequences of failure higher than original consequences of failure, (5) Site Class F (such as liquefiable soils), and (6) presence of geologic hazards. |
