Abstract
Sharing construction project data among the construction supply chain (CSC) stakeholders (e.g., Architects, General Contractors, Subcontractors, and Suppliers) is critical for the successful delivery of construction projects within time, budget, and expected quality. Building Information Modeling (BIM) is an advanced technology for the stakeholders to create and share the construction data. However, BIM data is not effectively shared among the stakeholders because of the difficulty in determining BIM data ownership and the ambiguity in clarifying who will be responsible for BIM data inaccuracies. Consequently, the stakeholders cannot trust that their data are safe from data ownership and liability issues, hesitating to share their data. This study examines the potential of blockchain to address the limitations of BIM by analyzing blockchain use cases in construction and other industries. Furthermore, based on the findings, this paper proposes a novel framework for a blockchain-enabled BIM data sharing application to improve the quality assurance process in the CSC. This study contributes to the body of knowledge by 1) enabling the construction industry to understand the potential of blockchain through construction and other industries’ blockchain use cases and 2) providing a practical framework for blockchain-enabled BIM data sharing to improve the quality assurance process in the CSC.
