This study explores the critical need to enhance interoperability in the Architecture, Engineering, and Construction (AEC) industry by integrating blockchain technology with Building Information Modeling (BIM). In today's Industry 4.0, where robust digital platforms are essential, decision-making often involves navigating uncertainty and imprecision. We utilize the fuzzy TOPSIS method to evaluate essential factors related to BIM and technology-related that are crucial for the industry's advancement. The research begins by pin-pointing key performance indicators (KPIs) for BIM and blockchain integration, highlighting their importance in improving interoperability. The paper delves into the basics of blockchain technology, showcasing its potential in the AEC field, particularly in ensuring data immutability, transparency, and the execution of smart contracts. It also provides insights into the technical complexities of merging blockchain with BIM systems, supported by real-world examples that demonstrate the practical benefits of this innovative combination. By employing the fuzzy TOPSIS approach, the study measures the significance of key factors such as data integrity, security, scalability, and regulatory compliance in AEC projects. This comprehensive evaluation framework arms decision-makers with the necessary tools for effective prioritization. The findings reveal the substantial impact of technology-related factors on construction projects and advocate for the adoption of blockchain-enhanced BIM integration. This study highlights the effectiveness of the fuzzy TOPSIS method as a tool for assessing BIM and technology factors, suggesting a pathway toward improved interoperability, and fostering collaboration and innovation in the AEC industry. This approach aligns with the industry’s vision for a future characterized by technological integration, efficiency, and excellence.
