Simplified methodological approach for repair time based on workforce population distribution of building portfolios from a resilience perspective

Abstract

Recovery from catastrophic seismic events is subjected to multiple aspects involving the resilience capacity. Disaster Risk Reduction management includes policies focus on preparedness to overcome the challenges associated to response on a post-disaster event. Most of those covers up the distribution of available resources to recovery from the damage state for the whole elements-at-risk. This paper presents a simplified methodology to estimate the maximum repair time using the distribution of resources through workforce population for intervention of building portfolio. This approach uses the risk metric: average annual repair time and the workforce population capacity. The risk metric could be obtained from conventional probabilistic seismic risk assessment. Therefore, several scenarios are defined to estimate the total repair time to recovery based on the percentage of the workforce population capacity. This gives a simplified tool for policymakers to stablish the thresholds limits for allowable repair time and percentage of population used for recovery. Finally, an example of its application is presented for a school building portfolio.
