Rail Baltica Alliance: Developing Shared Digital Overview with Open BIM

Since 2011, around 100 alliance projects have been launched or completed in Finland, with a combined value exceeding €11 billion. Most have been delivered on time and within budget, demonstrating the model’s effectiveness.

The alliance approach has now also been adopted in Estonia, where it is being used to deliver the Rail Baltica railway from Tallinn through Poland to Germany. Based on shared goals, open collaboration, and joint risk-benefit sharing, the alliance model has provided a strong foundation for improving project management and integrating stakeholders.

In recent large-scale tramway projects, stakeholders have jointly developed digital situational awareness, though often in isolated, project-specific ways. To address this, Finnish industry actors have joined forces to build a unified digital overview based on the Open BIM model, with shared data definitions and common interfaces. This development work is now intended to continue within the Rail Baltica Alliance.
