Blockchain-based Building Information Modeling

Abstract

Building Information Modeling (BIM) is a 3D real time and dynamic building modeling software that is used to enhance productivity in designing and constructing buildings. BIM is also a process to create and manage building information throughout building life cycle. BIM is used by many parties such as building owner, contractor, architect, engineer, site manager and facility manager. Thus to enhance security of BIM, we propose a new technology called blockchain. Blockchain has security features that can benefit BIM such as immutable and impossibility to be tampered with and forged, The features makes blockchain have incomparable advantages in ensuring information credibility, security and traceability. Thus, the objective of this research is to assess application of blockchain technology on Building Information Modeling (BIM). Construction management based on blockchain-based BIM could enhance information system security.
