A Blockchain and Decentralized Cloud Framework for Trust-free Automated Progress Payment of Construction Projects

Abstract: The payment issues in construction projects present major challenges for successful completion of projects. In this proceeding a framework is presented for achieving trust-free automated progress payment of construction projects to eliminate or reduce the payment issues. The framework integrates blockchain, smart contracts, Building Information Modeling (BIM), robotic reality capture solutions, and decentralized cloud technologies for accomplishing automated progress payments without any involvement of the project participants. Achieving a trust-free automated progress payment system would enable secure, efficient, timely and transparent payment of construction projects and would also eliminate payment related trust issues among the project participants.
