About the Event

WTC2026 serves as the annual gathering of the International Tunnelling and Underground Space Association (ITA) and will also host the organisation’s 52nd General Assembly. The congress brings together tunnelling and underground space professionals from across the globe to share knowledge, discuss industry developments and address current challenges in underground infrastructure. The 2026 edition is themed Connecting Communities Through Underground Infrastructure.

The Conference

The technical programme covers a broad range of subjects relevant to the tunnelling and underground space sector. The congress includes technical sessions, keynote presentations, training courses and technical visits. It provides a platform for professionals including engineers, contractors, project owners, academics and policymakers to exchange expertise and experience across all aspects of underground construction and infrastructure planning.

The Exhibition

WTC2026 will feature an exhibition offering organisations the opportunity to present products, services and innovations to an international audience of tunnelling professionals. Sponsorship and exhibition opportunities are available for companies seeking visibility within the global tunnelling community.

The city is noted for its multicultural character, extensive underground pedestrian network and established infrastructure for large-scale international events. A congress dinner is also scheduled as part of the week’s activities.
