Integrating Blockchain and BIM (BCT-BIM) to Promote the Construction Practices in Terms of Efficiency and Transparency

Abstract

Inefficiency, opaqueness, and dispute are the evils that cling to the body of construction. Blockchain, combined with BIM, can be an alternative to these issues. Trustable and Transparent: BCT ensures authenticity and transparency against records that cannot be repudiated as the fact records are available for decentralization on BCT, immune to third-party tampering; with the opportunity of Building Information Modelling (BIM) data-driven project execution efficiency improvement, such as data-rich collaborative environment that is being support in pre-checked information’ relevancy and feasibility based on (BIM). This study examines the potential of BCT and BIM, separately (BCT-BIM), in improving efficiency and transparency in the overall construction facilities’ lifecycle. A field survey was conducted in order to explore the most significant factors that were contributing to such integration. The findings reveal that the soundness of (BCT-BIM) integration is contingent on digital infrastructure, data security within organizations, and between actors. Furthermore, strategic planning, technological adoption, continuous workforce development, and effective stakeholder communication are key drivers of improving the construction sector’s efficiency. In context, transparency can be increased through the adoption of (BCT), open communication, and contract clarity. The researchers propose a prototype model to illustrate the automation of smart contracts linked to (BIM) milestones, which significantly improves payment accuracy and transaction transparency, subsequently developing efficiency and transparency in the construction production processes. This study confirms that (BCT-BIM) integration has the potential to improve construction practices in terms of being more transparent, efficient, and reliable project delivery.
