With the growing complexity of financial an‎d contractual relationships in construction projects, challenges such as payment delays, lack of transparency, an‎d disputes arising from change orders have become critical issues in project management. These challenges are particularly significant in EPC projects, where frequent change orders an‎d strong cash flow dependencies exist. Meanwhile, emerging technologies such as Building Information Modeling (BIM) an‎d Blockchain offer new opportunities to transform traditional payment an‎d change management systems. The aim of this research is to develop an integrated an‎d operational framework for intelligent payment management based on work progress, considering change orders during the construction phase. The proposed framework is developed in accordance with the AACE Recommended Practice 100R-19 an‎d the FIDIC Silver Book (2nd Edition, 2017). This study adopts a mixed analytical–modeling an‎d software development approach. The Dynamo environment within Revit was used to automatically identify an‎d classify design changes, while the Solidity language was employed to implement Blockchain-based smart contracts. In addition, a decentralized web application was designed to facilitate transparent an‎d automated interactions among the Employer, Contractor, an‎d Employer’s Representative for change approval an‎d payment execution. The results demonstrated that the proposed framework can significantly reduce payment processing time from weeks to days, enhance transparency an‎d auditability, minimize contractual disputes, an‎d improve cash flow performance. The main innovation of this study lies in the integration of BIM an‎d Blockchain technologies an‎d the establishment of a data linkage between the BIM model an‎d the smart contract, providing a foundation for transparent, automated, an‎d data-driven payment systems in the construction industry.
