Blockchain BIM
Success Story: Italferr
OYB developed the BIMChain application in collaboration with Italferr, an engineering company part of the Ferrovie dello Stato Group. This innovative solution integrates blockchain technology to ensure the authentication and security of data provenance, ownership, and integrity throughout the BIM (Building Information Modeling) production transfer process, enhancing reliability and transparency standards in the industry.
e-BIM Solution
e-BIM: A solution for managing processes, data, documents, and 3D models developed by our partner, e-Metodi. This innovative platform integrates process, data, document, and 3D model management into a single system, adhering to the ISO 16739-1:2018 Industry Foundation Classes (IFC) standard and utilising technologies such as openAPI 3.0 and blockchain.
Blockchain Application for BIM File Management
Validation of Data Provenance and Integrity
We have developed a system capable of tracking the source of the data and ensuring its integrity over time. The BIM-Blockchain solution guarantees information and data security, traceability, and transparency.
Process Exchange Validation
Our solution enables the traceability of the data exchange process with external parties through validation of the sender and recipient and the process of exchanging and sharing BIM files
Legal protection of know-how
We have created an application that allows you to track and verify the information associated with the data and which can be of support for the legal protection of know-how, such as the role and skills of the file owner, exchange and communication process, recipient of the exchange process and right of use associated with the transfer of the file.
Blockchain and BIM
The combination of BIM and Blockchain is revolutionising the design world by ensuring transparent and traceable collaboration among all stakeholders involved in processes. BIM relies on interoperability, collaboration, communication, and coordination among the various actors throughout a structure’s lifecycle. Blockchain enables the creation of a system that transparently tracks all exchanges, making them secure and reliable.
