World Tunnel Congress 2026
The International Tunnelling and Underground Space Association’s flagship congress, with a record technical programme.
Where the industry talks shop.
Conferences, congresses and short courses where our engineers present, exhibit, and — more usefully — listen.
Where to find us next.

Want our engineers on your programme?
We present regularly on ground behaviour, temporary works, tunnelling in ground that does not behave, and the forensic side of construction claims. If your conference needs a speaker who will tell you what actually went wrong on a real job rather than what the brochure says, we are interested.
Missed one? Read the papers.
Technical papers, case studies and slide decks from the events we have already spoken at.
