Czech Tunnelling Association

The Czech Tunnelling Association (Česká tunelářská asociace, CzTA) is the Czech national member of the International Tunnelling and Underground Space Association (ITA/AITES), which is headquartered in Lausanne, Switzerland. It brings together organisations, university and scientific workplaces, companies and individuals interested in underground construction in the Czech Republic. The association is an open organisation whose members may include anyone engaged in activities related to underground construction and the associated scientific disciplines. At the time of the source material, it had 43 collective members and 50 individual members registered. The association traces its origins to the Czechoslovak Tunnelling Committee, founded in 1982 on the initiative of enterprises involved in the construction of the Prague metro. After the dissolution of the federation, the Czech Tunnelling Association was established from that committee. It is therefore a professional and technical membership body rather than a commercial construction firm, although its collective members include companies active in the tunnelling and underground construction sector. CzTA's activities centre on professional exchange, publishing and events. It publishes news and updates on underground construction in the Czech Republic and Slovakia, maintains a web presence at ita-aites.cz, and is associated with the journal Tunel, in which a long-running series on underground construction postcards has appeared since issue 2/2014. It also supports the Podzemní stavby Praha (Underground Construction Prague) conference, whose 16th edition was held on 25–27 May 2026. Through its national membership in ITA/AITES, CzTA connects the Czech underground construction community to the international tunnelling field.

The Czech Tunnelling Association (Česká tunelářská asociace, CzTA) emerged from the Czechoslovak Tunnelling Committee, which was founded in 1982 on the initiative of enterprises involved in the construction of the Prague metro. That committee served as the professional platform for Czechoslovak tunnelling expertise during the era of major metro and underground infrastructure works in Prague. After the dissolution of the Czechoslovak federation, the Czech Tunnelling Association was established from the Czechoslovak Tunnelling Committee. It became the Czech national member of the International Tunnelling and Underground Space Association (ITA/AITES), headquartered in Lausanne, Switzerland. In this role, CzTA represents the Czech underground construction community within the international tunnelling association and maintains links with counterpart national organisations. The association is an open organisation. Its membership comprises organisations, university and scientific workplaces, companies and individuals interested in underground construction and related scientific disciplines. At the time of the source material, 43 collective members and 50 individual members were registered. CzTA's public activities include publishing news and updates on underground construction in the Czech Republic and Slovakia, covering projects such as metro D, the Hangár G collector, and the Jizerní Vtelno, Okruhliak and Španí Háj tunnels. It maintains a website at ita-aites.cz and is associated with the journal Tunel, where a series of postcards on underground construction has been published since issue 2/2014; individual instalments of that series have been made available on the CzTA website. The association also supports the Podzemní stavby Praha (Underground Construction Prague) conference, whose 16th edition was held on 25–27 May 2026.
