In focus


The blue pages highlight different topics like loans and financing agreements, infrastructure investments programmed by such or such country, booming markets, contractual disputes and litigation, etc.

Tunnels under study

The red pages describe future tunnel projects, still in the study phase and early engineering stages of development or even just proposals. This section gives a precise idea of what’s up next. It is often an opportunity for companies to be aware of new projects never or hardly heard of before to approach and advise the owners and developers. As many technical details as possible are given about tunnels and underground structures described. The articles are often illustrated with maps and studded with click-through web links.


Invitations to tender


The green pages report about requests for proposals, expressions of interest, invitations to tender and calls for bids related to engineering studies, civil works and construction supervision for new tunnels. Shortlisted/prequalified companies are disclosed when available. Technical details are provided as well as contact people and web links to the tender announcements and associated documents.

Contract announcements

Events and recognition

alt The black and white pages pay attention to the important conferences, symposiums, training courses and congresses for tunnelling and trenchless construction professionnals. It also reports about prizes awarded to outstanding projects and eminent people.
