Tunnels and Underground Works
Advanced expertise in underground engineering
CSC Costruzioni has developed highly specialized expertise in the field of underground works over time, gained through its involvement in the delivery of some of the most complex projects in Europe. This experience represents a unique technical and operational asset, enabling the company to address extremely challenging geological and construction environments through a reliable and innovative engineering approach.
Road and railway tunnels, as well as energy and service infrastructures, represent areas where our expertise is expressed at the highest level, thanks to our ability to integrate specialized know-how, advanced technologies, and rigorous management of construction processes.
An experience built on major European projects
The expertise of CSC Costruzioni’s teams has been strengthened through their involvement in the delivery of some of the most significant underground infrastructures in Europe.
These include the Gotthard Base Tunnel, the Ceneri Base Tunnel, the Brenner Base Tunnel, and the TELT project (Turin–Lyon railway connection), all landmark projects in European railway engineering.
These experiences are complemented by other major projects, such as the Col des Roches works, the Eyholz tunnel, the Silvaplana project, and the underground infrastructures developed for Swissgrid in Martigny. These construction sites have enabled our teams to develop advanced expertise in managing complex geotechnical conditions, underground safety, and the optimization of excavation and ground reinforcement processes.
Technical approach and project management
Each underground project is approached through a multidisciplinary methodology that combines engineering, planning, and innovation. The complexity of these interventions requires strong integration between detailed design and execution, with particular attention to the management of geological risks, operational continuity, and construction quality.
Our teams work in close collaboration with clients and technical partners, ensuring continuous control of activities and a high capacity to adapt to site conditions, even in the most challenging environments.
Innovation and sustainability in underground works
Technological innovation and sustainability are also key elements in underground works. The adoption of advanced excavation techniques, the efficient management of excavated materials, and the optimization of production cycles help reduce environmental impact and improve the overall safety of operations.
This approach makes it possible to combine high technical performance with increasing attention to environmental considerations and the long-term durability of infrastructure.
A contribution to the infrastructure of the future
Thanks to this experience gained through the most important European projects, CSC Costruzioni is now able to contribute to the development of strategic underground infrastructures, ensuring high standards of quality, safety, and reliability.
Underground works therefore represent not only an engineering challenge, but also a field in which the Group fully demonstrates its ability to innovate and create value for the transport and energy networks of the future.
Excavating connections, opening new perspectives
For CSC Costruzioni, every tunnel is much more than an engineering work: it is an infrastructure that overcomes distances, connects territories, and creates new development opportunities, generating lasting value for communities and future generations.
