North and south extension of the Liège tramway

The Challenge

The project required seamless integration with an operational line, meaning every proposed solution had to be fully interoperable between the existing infrastructure and its planned extensions. This constraint introduced significant complexity in terms of technical compatibility, safety standards, and operational continuity, demanding meticulous coordination across multiple stakeholders and disciplines.

The Solution

To address these challenges, Tractebel implemented a rigorous interface management process, ensuring that all systems and components aligned perfectly with the existing line. Continuous collaboration was maintained through regular contact with the designers of the historical line, enabling proactive identification of potential conflicts and fostering a shared understanding of technical and architectural requirements. This structured approach minimized risks and guaranteed interoperability throughout the project lifecycle.

The Impact

The result was a functional and harmonious extension, achieved through excellent collaboration between the design office and the urban architect. The project not only met operational and technical objectives but also respected the identity of the city and its natural environment, delivering an infrastructure solution that blends performance with aesthetic and ecological considerations. This synergy underscores Tractebel’s commitment to sustainable, integrated urban development.
