The ITA-AITES World Tunnel Congress 2007 (ITA WTC 2007), which was organized by the ITA/AITES Czech Tunnelling Committee, started on Monday the 7th May 2007 at the Congress Centre in Prague, the capital of the Czech Republic. Some related events and meetings of the ITA bodies commenced in advance, on Friday the 4th May 2007.
The Congress motto was: „Underground Space – the 4th Dimension of Metropolises“.
The negotiations of the Congress itself ended on Tuesday the 9th May 2007; one-day technical excursions to Prague tunnel construction sites followed on Thursday.
The qualityof the Technical Programme was high and the range of topics very wide.
The Keynote Lectures and the ITA Open Session were important parts of the Technical Programme.

The Opening Ceremony of the Congress held on Monday morning, was followed by four lectures presented by outstanding worldwide experts, the Keynote Lectures. They depicted the current state of the tunnelling industry in four areas, namely:

  • The opening lecture “Tunnels in Metropolis” was presented by Professor Zdenek D. Eisenstein from Canada. He provided lot of information on the overburden deformation during the driving tunnels in cities all over the world. Among other tunnels, he mentioned the subway driving through soft ground using EPB TBMs in Los Angeles, where zero surface settlement values were recorded.·
  • The tunnelling by TBMs was the topic addressed by Professor Marcus Thewes from the Ruhr University in Bochumi, who worked with Herrenknecht in the past. 
  •  Professor Jian Zhao arrived to present his lecture on problems of tunnelling in rocks from Laussane.
  • The tunnelling in stiff clays was the topic of the lecture given by Mr. David Powell from Britain, who is the chief specialist in Matt MacDonald’s London branch.

All four lectures were published in an extraordinary issue of TUNEL, which is published by the Czech Tunnelling Committee jointly with the Slovak Tunnelling Association.
The morning programme of the second day of the Congress negotiations consisted of the ITA Open Session. Its topic was: „New financing trends and consequences on the tunnelling contracts“.
The lectures were given by representatives of the European Investment Bank, the re-insurance sector, owners, contractors and other organizations.

1. European Investment Bank - Henry MARTY-GAUQUIE
2. Financial Investor - VINCI Concession - Vincent PIRON
3. Contractor – Holfelder Martin, Bilfinger-Berger Bau
4. Engineering sector - Yann LEBLAIS
5. Contractual aspects - Arnold DIX
6. Re-Insurance sector - Wannick HEIKO (Munich-Re)
7. Owner – Emanuel Šíp (MD ČR)

The Technical Sessions were held simultaneously in four halls during three days. Individual topics were discussed in 9 sections, with 129 lectures delivered in total. The themes of the sections covered the entire sphere of subterranean construction, starting from the planning of the use of the underground space of towns and underground town planning, through geological survey and improvement of rock mass properties, urban tunnelling, concrete in underground construction, to historic underground structures, concrete for underground construction, risk management, tunnel equipment, underground structures and the maintenance of underground structures.

The Technical programme further contained an extensive Exhibition, which attracted 80 exhibitors from all over the world, and the Poster Session. The 70 posters were presented.

The one-day excursions which were held on Thursday the 10th May 2007 were attended by 408 persons of the 460 persons who had applied for the registration. The excursion to the construction site of Metro IVC2 was highest attended (201 persons).

The Congress was preceded by a highly successful two-day Training Course, which was focused on urban tunnelling. It was held on Friday the 4th May and Saturday the 5th May 2007. It was intended above all for young engineers but, because of the high level of lectures, there were also other people well skilled in the tunnelling. The Training Course was attended by 125 guests, 38 of them were foreigners from 15 countries. Three lectures of the total of 19 were given by authors from the Czech Republic and Slovak Republic.
