Abstract

Downtime -as the time necessary to restore a system's functionality- is the critical parameter of the recovery process after an abrupt event. This quantity is usually underestimated to the repair time, while the recovery process also includes the “recovery initiation delay”. The paper tries to use a model to estimate the time needed to start the building repair after the hazard occurrence. Among several factors affecting downtime, those external to the building play a key role in determining this duration. Such factors are strongly dependent on community relationships. External factors - including transportation access, building inspection, utility disruption, financing, etc. - from Loma Prieta earthquake are compiled and analyzed in order to investigate the relative effect of community dependent factors on building recovery initiation delay. A sensitivity analysis is done, as different factors do not have the same influence on recovery path.
