This study aims at establishing an LCP (Life Continuity Planning) evaluation method for assessing the possibility of continuing life in ownership condominiums in the wake of a great earthquake. This paper identifies risk factors as the basis for LCP evaluation and extracts evaluation factors that represent the measures against the risk factors.
Based on the results of interviews made in existing works, six primary post-earthquake risk factors that occurred at affected condominiums were extracted, namely, injuries, confinement, escape, fires, poor information communication and disruption. Six secondary risk factors related to the continuation of life were also identified, namely, power failure, water stoppage, poor water discharge, discontinuation of gas supply, difficulty in movement and hardships incurred by lack of food and bedding. Then, questionnaire surveys were conducted and asked residents in condominiums about their greatest worry at the time of a great earthquake by delivering free-answer questions. As a result, the above twelve risk factors that occurred in affected condominiums proved to be valid evaluation factors because the respondents specified nearly all of the factors and the residents recognized such risk. The twelve risk factors were further classified as the basis for LCP evaluation and evaluation factors were established. Then, LCP evaluation factors were developed for condominiums.
