RC structure durability information model based on IFC

An extension of the BIM technology that allows integrating durability factors into designing process, appraising durability and predicting residual life of building structures is proposed. Furthermore, by integrating national durability code, achievements of durability researches and the IFC standard which is developed by International Alliance for Interoperability (IAI) with the standard number of ISO10303 to facilitate AEC information sharing and exchanging, a BIM-Based Durability Appraising Software System for Reinforcement Concrete Structure is developed. The durability information model and IFC data interface are elaborated. Then the system is verified by a case study to be capable of improving lifecycle management of AEC projects, upgrading durability level and optimizing the lifecycle cost structure of building projects.
