Abstract: In the chaotic aftermath following a major earthquake, building owners often need rapid, accurate, and reliable damage information to resume occupancy or take appropriate measures for building recovery. Within 3-10 days of the event, municipal-deputized safety evaluators typically provide a rapid safety assessment.|However, to completely assess the building's condition, a more detailed structural assessment is often necessary. Without prior arrangements, owners may have to wait weeks to coordinate with a qualified structural engineering professional. To avoid this delay, some jurisdictions have adopted programs based on the Building Occupancy Resumption Program (BORP) developed by the City and County of San Francisco that allows owners to pre-certify qualified structural engineers for post-earthquake inspection of their buildings. In non-participating jurisdictions, a similar "unofficial" approach can facilitate the post-earthquake assessment efforts. This paper outlines the basic BORP phases and provides recommendations for alternate programs based on building owners needs.
