Consulting with Passion

Any professional consulting can be only as good as the practical experience behind it.

We have over 20 years of experience in tunnel construction on all 5 continents and share our experience in all areas of tunnelling. Having participated in big international design companies, we do also review, evaluate and advise planning works. Furthermore, we give technical workshops on all topics of tunnelling.

Our credo is knowledge-sharing.


Tunnelling is a daily adventure because it's notoriously dark at the hoe.

Well advised is who seeks good advice. It is not about knowing things better, but to complement valuable knowledge from experience.

We are specialists in tunnelling and all related fields.


Our services are very manifold and spread around the following main columns:
