Toward Construction Payment Automation by Integrating BIM and Blockchain Technology

The construction industry encounters persistent obstacles, such as payment delays, disputes, and transparency, which hinder project efficacy and stakeholder confidence. To resolve these issues, this study proposes a transparent and automated construction payment approach by integrating BIM with its precise project data and blockchain, decentralized ledger, and smart contract capabilities. The new approach illustrates how BIM can facilitate precise progress monitoring and milestone verification while blockchain ensures secure, real-time payments upon milestone completion. The findings indicate that this integration encourages transparent payment processes, drastically reduces disputes, and enhances stakeholder trust, thereby reshaping the financial landscape of the construction industry and improving project outcomes. The research also discusses technical, security, and regulatory considerations, providing an all-encompassing view of the practicability and benefits of this innovative approach. The research contributions prove that incorporating BIM and blockchain can revolutionize construction payments by rendering them more efficient, transparent, and adaptable to the industry’s changing requirements.
