Tunnelling - for the infrastructure of the future

Special geological features, high-tech processes and state-of-the-art machinery - underground construction is one of the most demanding disciplines in civil engineering. At the same time, the construction, modernisation or repair of tunnels is one of our core competencies.

Whether it is the successful completion of tunnelling projects for road, rail, district heating supply, sewage systems or pumped storage power plants: our versatile references prove our expertise and flexibility in tunnelling.

From underground railway construction in inner-city conditions, conventional tunnelling in shotcrete construction to high-tech mechanised tunnelling: We meet challenges with technical expertise, flexibility and innovative strength. This is why we are one of the leading providers in tunnelling, not only in Austria but throughout Europe. The basis for efficient and successful project execution includes innovative, digital planning and working methods as well as lean processes.
