2023 | ONGOING
Since early 2023, TunnelPro has been involved in the Salerno–Reggio Calabria High-Speed Railway project, with particular reference to Lot 1A Battipaglia–Romagnano, supporting Ghella in the development of the Technical and Economic Feasibility Design during the tender phase.
In 2023, TunnelPro joined the Xenia Consortium, awarded the contract for the works.
For each of the four EPB (Earth Pressure Balance) TBMs — three with a diameter of 13.4 m and one with a diameter of 9.9 m — deployed for the excavation of the Battipaglia–Romagnano section, TunnelPro was responsible for the preliminary construction planning study, site logistics setup during the machine start-up phase, and the analysis of methodological, logistical and organizational optimizations related to mechanized tunnelling operations.
Throughout numerous technical meetings with the TBM manufacturers, both during the design and construction phases, the head office engineering department actively contributed to the definition of the technical specifications, ensuring full consistency between the adopted solutions and the functional and operational requirements necessary to execute the works in compliance with project specifications.
Since 2024, TunnelPro has also been providing specialist consultancy on the geological aspects of the project and on ground conditioning methods, while supporting the site procurement department in the sourcing of materials and equipment.
From 2025 onwards, the engineering department has been engaged in the review of detailed design documents, with particular reference to site layout drawings during the storage phase, the definition of TBM launch procedures, and the dismantling of TBM 3, which will operate in tunnel GI09.
Furthermore, at the end of 2025, TunnelPro was appointed by the Xenia Consortium to provide technical assistance for the lifting and relocation of the TBMs and to develop the methodology and procedures required to allow the machine backups to cross existing viaducts without dismantling. The engineering department prepared a series of technical drawings to support this delicate operational phase, enabling the repositioning of the TBMs between excavation drives with significant time savings compared to conventional methods.
In parallel, TunnelPro delivered technical assistance services related to the identification and specification of the spare parts required to ensure the timely execution of routine maintenance activities for the TBMs and all auxiliary equipment employed in the mechanized excavation of the tunnels.
