TUNNELLING IN BELGIUM
Though geographically small, Belgium has a remarkably diverse tunnelling landscape that reflects both its historical legacy and modern-day innovation. With a long-standing need to develop underground infrastructure in densely populated and geologically varied areas, Belgium has accumulated extensive experience across nearly all tunnelling techniques.
Major projects like the Oosterweel Link in Antwerp — one of Europe’s most ambitious mobility initiatives — and the development of urban metro systems in major cities demonstrate the country’s expertise in integrating tunnels into complex environments.
Belgian engineers and contractors are known for their practical experience, technical excellence, and commitment to safety and sustainability. Belgium has also embraced modern contract models and procurement strategies in recent years. Collaborative approaches such as Design-Build (DB), Design-Build-Finance-Maintain (DBFM), and alliancing are increasingly used to deliver complex tunnelling projects. These methods aim to improve risk sharing, encourage innovation, and foster stronger partnerships between public authorities, designers, and contractors.
With a growing focus on climate resilience, underground space is increasingly seen as a solution for mobility, energy, and water management. Tunnelling in Belgium continues to evolve, contributing valuable knowledge and experience to the global tunnelling community.
