Together, these features create an unalterable and transparent record, mitigating the risks of data loss, corruption, or unauthorized alterations. Blockchain's role in preserving data integrity is a foundational element for reliable and trustworthy BIM project outcomes.

Data integrity in BIM projects refers to the accuracy, completeness, and consistency of data throughout its lifecycle. However, maintaining data integrity can be challenging due to potential issues like loss, corruption, or tampering. Blockchain technology offers a solution by using hashing and consensus mechanisms to secure and validate data transactions. Hashing converts data into unique and fixed-length codes, ensuring its identification and encryption. Consensus mechanisms enable agreement among network nodes regarding the validity and order of transactions. By employing these techniques, blockchain creates a permanent and immutable record of data history, preventing unauthorized changes and enhancing data integrity in BIM projects.

Data integrity and blockchain work together in a powerful synergy to significantly improve data security and trust in BIM projects: - >Ensuring Accuracy and Consistency: Data integrity focuses on maintaining the accuracy, completeness, and consistency of data throughout the BIM lifecycle. This includes preventing errors, omissions, and unauthorized modifications during model creation, sharing, and updates. >Validation and Quality Control: Various tools and protocols are employed to validate data against standards and project requirements, identifying inconsistencies and ensuring quality control. Regular audits and reviews further uphold data integrity.

we can establish a robust data ownership system, which will assure that consistent and unaltered information is upheld. This not only bolsters security but also cultivates trust among stakeholders, ensuring that the shared data remains reliable.

In the AEC industry, data access in BIM projects often needs to be improved due to siloed or incompatible systems and centralised control. This impedes efficient data management and project success.
