Revealing Inherent Rules and Validation Frameworks for Evaluating BIM Data Regarding Disaster- and Resilience-Related Regulations

Multi-layered and cross-referred disaster resilience regulations and building codes have been a critical obstacle to holistically evaluating long-term resilience of a residential building according to various disaster scenarios. This challenge is caused and worsen by the primary knowledge gap, which is the lack of integrated and executable regulatory rules and specifications related to disaster resilience. To tackle this issue, the authors have identified fundamental resilience rules and built a disaster resilience validation framework that incorporates formalized, but implementable resilience requirements. To accomplish this goal, we thoroughly investigated multi-layered flood-related regulations and revealed their inherent rules for validating the disaster resilience of a single-family house. We identified 42 resilience-related rules and developed them in an implementable format using the eXtensible Markup Language (XML) schema for broadly disseminating them to related domains. The rules include the flood resilience features dealing with lowest floor elevation and freeboard requirements, openings of building walls, breakaway walls for elevated buildings, and obstruction-free buildings in coastal areas. The revealed rules play a pivotal role as a foundational baseline to establish a web-based automated validation system that can assist the public to evaluate building information modelling data. The proposed approach is expected to help logically assess the resilience of buildings and consistently share their updated regulations.
