Information requirement definition for BIM: A life cycle perspective

Adopting the Building Information Modeling (BIM) methodology assists in fulfilling stringent cost and time objectives in architecture, engineering, construction and facility management industry. To enable further adoption of the technology a life cycle oriented approach needs to be pursued. In this work, information requirements for the whole life cycle of a building are defined and the capabilities of existing BIM models to assist the identified information areas are evaluated. The results indicate missing support on information about equipment efficiency curves, description of decentralized energy conversion devices, occupant behavior, thermal and visual indoor comfort and information on the preservation status. Furthermore, to support future BIM model development, the novel information management method GASCEeIiL is presented which allows tracing the use of a piece of information by each stakeholder along the information life cycle.
