Construction Class Descriptions

AIR provides the following categories of construction class codes.

  Touchstone applies non-engineered building damage distributions to the following construction classes regardless of occupancy class, including the industrial facility (400-series) occupancy classes: 101, 102, 103, 104, 111, 112, 113, 114, 115, 173, 174, 178, 179, 261. This applies to the AIR Earthquake Model for Japan and to the AIR Earthquake Model for Canada.
