As digital collaboration becomes the norm in the construction industry, ensuring the authenticity and integrity of Building Information Models (BIM) is more critical than ever. While BIM and openBIM standards, such as the Industry Foundation Classes (IFC), have improved interoperability and data exchange, challenges remain in verifying data at the object level.

This presentation explores the potential of digital signatures as a solution to enhance trust, transparency, and traceability in BIM workflows. By securely signing BIM objects, digital signatures can ensure data integrity, authenticate contributors, and create a verifiable record of model changes. Additionally, the session will highlight how integrating digital signatures within IFC-based BIM processes can support compliance, reduce legal disputes, and improve collaboration across stakeholders.

Attendees will gain insights into the practical challenges of implementing digital authentication at the object level within BIMs and how emerging solutions could shape future best practices for secure digital project delivery.
