As part of this project, considerable attention has been paid to evaluating existing classifications and modifying classifications of construction types to ensure the most accurate depictions of performance. For purposes of the PAGER model, this means very detailed classifications, that distinguish among roof types, number of stories, etc. The file below lists PAGER construction types, and corresponding types from various other sources, such as HAZUS, WHE, EMS-98, Coburn and Spence 2002, and RISK-EU.
