A large portion of projects in the construction industry face issues related to delivery delays, including increased costs, claims, an‎d litigation. These problems can result from the lack of timely an‎d effective participation an‎d action by all project stakeholders (owner, contractor, consultant) in schedule management. This study presents a framework based on blockchain technology an‎d four-dimensional Building Information Modeling (BIM4D) that, by creating a decentralized, transparent, an‎d trustworthy platform for information sharing an‎d payment management, enables active stakeholder participation in project scheduling an‎d resource provisioning. The performance of the proposed framework in this study is eva‎luated using the Critical Path Method (CPM) an‎d Critical Chain Project Management (CCPM) in a case study, an‎d costs are measured under different scenarios. Comparison of the results from the case study shows that applying the framework, in addition to reducing time an‎d preventing delays, leads to a significant reduction in costs exceeding the original contract amount. The findings of this research demonstrate that using blockchain technology an‎d BIM4D in construction project scheduling has a significant impact on reducing delay-related costs an‎d improving management processes. Stakeholder participation in schedule management is made possible through the secure an‎d reliable blockchain platform (providing trustworthy real-time information for timely action an‎d trust in parties’ commitments due to the non-repudiable logic recorded in the smart contract).
