Discover the congress
The World Tunnelling Congress (WTC) is the largest recurring event of the International Tunnelling and Underground Space Association (ITA-AITES), gathering engineers, contractors, owners and researchers from around the world to share the latest advances in tunnelling and underground space technology.
Every edition is run by a different local organizing committee, and each congress has its own website on ita-wtc.org — with its registration, programme, speakers, exhibition and travel information — alongside its own congress app.
