ITA World Tunnel Congress 2026 in Montréal: Global Underground Engineering Event

The International Tunnelling and Underground Space Association (ITA), in collaboration with the Tunnelling Association of Canada (TAC), will host the ITA World Tunnel Congress 2026 in Montréal, Quebec, from May 15 to 21. The event is a premier gathering for professionals involved in the planning, design, and construction of underground infrastructure, including roads, railways, hydro projects, water and wastewater systems, flood control, and urban planning.

Under the theme “Connecting Communities Through Underground Infrastructure,” the Congress will feature technical sessions, discussions, and workshops covering all aspects of underground space development. Attendees will have access to the latest innovations in equipment, materials, products, and services showcased at the exhibition hall.

The three-day technical program will cover a wide range of topics, including contract practices, insurance, risk management, site investigation, instrumentation, excavation methods, immersed tunnels, caverns and shafts, microtunnelling, ground support, grouting, waterproofing, operations, maintenance, rehabilitation, and operational safety in underground works.

The ITA World Tunnel Congress 2026 provides an unmatched platform for engineers, contractors, manufacturers, suppliers, and clients to connect, share expertise, and explore opportunities in underground infrastructure worldwide.
