OFITECO, as part of a joint venture, will carry out principal inspections of 77 tunnels on the High-Speed Rail Network managed by ADIF along the Southern, Northeastern, Eastern and Northern corridors (excluding Galicia), a key undertaking to ensure the safety, functionality and maintenance of these strategic infrastructure assets.
This contract covers the inspection of more than 150 kilometres of tunnels along the country’s main high-speed rail corridors. The work will include periodic principal inspections and, where necessary, special inspections and supplementary studies to provide a more in-depth analysis of specific defects or issues identified.
The work will combine visual inspections with advanced data capture and analysis technologies. High-resolution 3D laser scanners and thermographic systems will be used to identify dampness, cracks, deformation, water ingress and other defects that may affect tunnel performance.
Detailed assessments of tunnel linings, drainage systems, sidewalls, crowns and trackbeds will also be carried out, generating graphical information and digital models to assess the condition of each infrastructure asset and monitor the progression of damage over time. A new feature of the contract is the inclusion of tunnel portal inspections, in accordance with ADIF’s specific standards for railway earthworks.
Where tunnel conditions require, the work may include monitoring programmes, geotechnical instrumentation, convergence measurements, testing and targeted studies. Technical recommendations may also be prepared to define repair or strengthening measures that help maintain the safety and reliability levels required for railway operations.
To carry out this work, OFITECO will draw on a multidisciplinary team specialising in surveying, geology, geotechnical engineering, structures, drainage and railway infrastructure, supported by advanced technologies for data capture and processing.
All results will be integrated into ADIF’s digital systems through the inclusion of reports, drawings, photographs and technical records. This will facilitate maintenance management and decision-making for one of the most significant elements of Spain’s railway network.
Through this project, OFITECO further strengthens its experience in the inspection and monitoring of complex infrastructure, helping to improve safety and understanding of the condition of tunnels on the High-Speed Rail Network.
