Event Description
CONGRÈS INTERNATIONAL DE L'AFTES 2026: Shaping the Future of Underground Infrastructure in Lille
Scheduled for October 12-14, 2026, in the vibrant northern French city of Lille, the CONGRÈS INTERNATIONAL DE L'AFTES stands as a pivotal event for the global underground construction industry. Organized by AFTES (Association Française des Travaux en Souterrain), this prestigious biennial gathering brings together leading engineers, researchers, contractors, consultants, policymakers, and academics from over 30 countries. It serves as the premier platform for sharing cutting-edge knowledge, debating critical challenges, and showcasing innovations that drive the development and sustainability of underground spaces worldwide.
Thematic Focus: Innovation, Sustainability, and Resilience
The 2026 Congress will revolve around core themes essential for the future of underground infrastructure:
1. Digital Transformation & Smart Tunnels: Exploring the integration of BIM (Building Information Modeling), AI, IoT sensors, digital twins, and advanced data analytics for design, construction monitoring, predictive maintenance, and optimizing tunnel performance and safety.
2. Sustainable Underground Solutions: Highlighting innovations in low-carbon construction materials, energy efficiency in ventilation and lighting, geothermal applications, integrating renewable energy sources, minimizing environmental impact, and promoting circular economy principles in underground projects.
3. Resilient Infrastructure for Future Challenges: Addressing the design and construction of tunnels and underground facilities capable of withstanding extreme events (climate impacts, seismic activity, flooding) and ensuring long-term durability and adaptability in a changing world.
4. Complex Projects & Advanced Techniques: Focusing on the engineering and execution of challenging underground works in urban environments (complex geology, deep excavations, sensitive surroundings), innovative tunneling methods (TBM advancements, NATM, sequential excavation), and large-diameter tunnels.
5. Safety Culture & Risk Management: Sharing best practices, new technologies for hazard detection and prevention, improving emergency response protocols, and fostering a proactive safety culture across the entire project lifecycle.
6. Optimizing Underground Space Utilization: Discussing innovative uses beyond traditional transport (storage, data centers, utilities, cultural spaces, climate adaptation) and strategies for integrating underground infrastructure more effectively into urban planning.
