SOCOTEC is leading a visionary project: the construction of the new L-9 line of the Metro, the longest in Europe. At 47.8 km, including 43.7 km underground, it represents a monumental breakthrough in underground engineering. This tender has been acquired thanks to our experience in Infrastructure Construction Management and we collaborated with TPF, Getinsa, Euroestudios and Tunelconsult to shape this innovative transport network.

Services Provided:
SOCOTEC, supported by its strategic partners, meticulously defines the design and detailed planning of the initial section of the L-9 of the Barcelona Metro. Our highly trained team oversees every phase of the project, ensuring flawless and on-time execution. In addition, detailed inspections and rigorous tests are carried out at facilities, stations and evacuation shafts to ensure quality and safety in each component. BIM technology and Tunel Data sensors provide a real-time view of the status and behavior of underground infrastructure.
Main Services:
- Construction project (studies and designs) of the first section of the L-9 of the Metro
- Management of the execution works
- Inspection and testing of installations, stations and evacuation shafts
- Geotechnical Project and Geological Profiles of the Tunnel
- Auscultation with sensors (Data Tunnel ) with BIM
Tunnel Boring Machine
Advances and Challenges from SOCOTEC's Technical Perspective
This tunnel boring machine represents a giant step towards a more efficient and sustainable infrastructure for Barcelona. It is a milestone in the history of engineering, consolidating SOCOTEC as the only company capable of leading the Construction Management of this project, guaranteeing its prosperity and safety at every stage.
The design of the tunnel has been conceived after exhaustive geotechnical and auscultation tests. The implementation of a tunnel boring machine in the final section ensures safety in changing conditions at depths of between 35 and 70 metres. This innovative approach places SOCOTEC at the forefront of tunnel engineering.

SOCOTEC is at the forefront of tunnel engineering by implementing a tunnel boring machine in the final section, ensuring safety at depths between 35 and 70 meters.
Monitoring and Geotechnics
Digitalization for safety and viability
SOCOTEC adopts current digitalization methodologies and implements BIM to ensure the rigor and control of information, meeting deadlines and achieving the optimization of public costs.
Inspections have been carried out in areas of influence through which the TBM would pass to ensure its passage. To this end, SOCOTEC has installed more than 2900 points with automatic and manual readings that allow total monitoring.
