Abstract: Managing data in construction projects faces significant challenges due to the high volume of information and execution complexities. Traditional systems for data recording and management often encounter issues such as human error, lack of accuracy, and high operational costs. This study eva‎luates and develops a blockchain-based system aimed at improving the accuracy and reliability of data in construction project controls. The research methodology includes designing an innovative blockchain-based model for data validation and analyzing its impact on payment accuracy and dispute reduction in projects. Initially, payment data were validated using a proposed consensus-based framework, followed by blockchain implementation. The model design involved surveying 12 construction industry experts, and weights were assigned to the project stakeholders based on four parameters. These weights were obtained through two types of online questionnaires and AHP comparative questionnaires from the experts. The framework utilized ERC-20 smart contracts on the Ethereum blockchain. The smart contract was developed using Solidity, the software with JavaScript, and the web interface was designed using HTML. The findings indicate that this method enhances transparency and reduces disputes related to project control data. Results show that the use of blockchain increases contractors' payment receipts by approximately 23% compared to traditional payment systems at the time of the study, thereby reducing claims and excess project costs. Moreover, the system improves the payment processes and project progress control. Based on statistical analyses and existing data, the proposed framework effectively addresses the shortcomings of traditional systems and contributes to improving the accuracy and efficiency of construction projects.
