ITA - International Tunnelling Association


Founded in 1974 by the initiative of nineteen Nations, the International Tunnelling and Underground Space Association (ITA) which aims are:

•  to encourage the use of the subsurface for the benefit of public, environment and sustainable development and

•  to promote advances in planning, design, construction, maintenance and safety of tunnels and underground space, by bringing together information thereon and by studying questions related thereto.

Since then, ITA has considerably developed. Presently, ITA gathers 64 Member nations and 310 Corporate or Individual Affiliate Members.
