Reliability evaluation plays a crucial role in the design, operation and maintenance of building and infrastructure facilities. Meanwhile building information modelling (BIM) technology has been widely used in life cycle assessment (LCA), rule checking and lean construction for its advantages in multi-platform collaboration and digital modelling. However, in the combination of traditional reliability theory and BIM-based life cycle assessment is still lacking, especially for component level computations. This paper proposes a reliability assessment framework based on BIM to realize the complementarity of these two technologies. The method is developed based on reliability model of different facilities and data interoperability function of BIM technology. The former considers the randomness and degradation effect of a c omponent, and the later makes it possible to transmit and share data information among different platforms. A reliability assessment example for a reliability-based design for a four-story reinforced concrete fram e structure are perform ed to demonstrate the proposed method. The results show that the proposed method can easily transform the design information in BIM into reliability information and the reliability for each component can well feedback to BIM model. The calculated reliability index can provide more valuable reference and theoretical basis for life cycle assessment.
