Abstract

With the advancement of Building Information Modeling (BIM) technology, BIM gains more importance and becomes a prerequisite in building projects. BIM is useful throughout a building lifecycle; from building bid, design, construction, completion, operation, and maintenance to building demolition. However, current information exchange surrounding BIM is still limited and bound to a single participant or organization and is also limited to a particular phase in the building lifecycle. This paper aims to explore BIM information exchange among many parties involved in a secure manner using a blockchain platform throughout the whole building lifecycle. In this research, many parties involved in the building project will be able to recognize one another through deployment of a permissioned blockchain. This information exchange uses Hyperledger Composer, a permissioned blockchain running on a blockchain platform called Hyperledger Fabric. Our experiment shows that BIM information exchange could be further improved. In this study, BIM information exchange can be implemented not only in one building phase but throughout the whole building lifecycle. It also facilitates BIM information exchange among multiple participants in a secure manner via a permissioned blockchain.
