Description du marché
The purpose of the present contract is as follows:
• project management services,
• execution of works,
• the provision of maintenance.
The project management services include the design studies for the structures, the monitoring and control of the execution of the works, and the establishment and implementation of the test programme. The contractor must identify an integrated project manager within its organisation who is responsible for these services.
The execution of the works includes the execution studies, the realisation of the secondary civil engineering works, the supply and installation of the equipment (railway and non-railway systems), the realisation of all the tests and trials required for the commissioning, and the supply of the emergency trains and bimodal transport.
The main elements of the secondary civil engineering are:
• the emergency and maintenance platforms along the entire length of the tunnel,
• the lining of the access adits and caverns,
• the finishing of the secondary works,
• the technical buildings,
• the construction site offices,
• the works and installations to reduce the impact on the environment,
• the final fittings.
The main systems included in the railway installations are:
• the track: slab track in the tunnel, on ballast outside,
• traction power supply: catenaries (25 kV), substations, transformation, distribution, high voltage connections (RTE up to 400 kV in France, TERNA 132 kV in Italy) and medium voltage (ENEDIS, Régie Municipale),
• signalling: ETCS level 2 (without superimposing with the automatic block), signal boxes interfaced with the adjacent control boxes of the french and italian networks,
• telecommunications including railway telephony and GSM-R (connected to the MSC RFI),
• control: centralised control room (railway traffic and installations), supervisor (SCADA) with multi-service broadband communication network and supervised equipment, digital innovation.
The main systems included in the non-rail installations are:
• medium/low voltage power supply,
• ventilation (comfort and safety), branch doors and odd/even communication doors,
• cooling/climate control (technical rooms and possibly tunnel), pumping and drainage,
• electrical distribution and low voltage lighting,
• safety equipment (communication, audio system, traffic video, sites video, access control, thermographic gates), firefighting (with Fire Safety System supervisor) and security,
• maintenance and measurement machines
• evacuation and rescue trains and bimodal vehicles,
• photovoltaic systems.
The realisation of the maintenance work includes, within the framework of the objectives defined by TELT:
• the preparation of a regularly updated maintenance plan allowing the triggering of curative or preventive maintenance operations (the ESM, not included in the present contract, will be proposed by the contractor and decided by TELT),
• the organisation and management of the maintenance teams,
• systems performance monitoring and data collected analysis (big data),
• planning and coordination of work slots in collaboration with the operators (TELT),
• management of material resources and supplies for maintenance.
The scope of the maintenance assignment includes the monitoring and routine maintenance of:
• the structures, installations and systems designed and built by the contractor,
• and of the other assets of the cross-border section (civil engineering structures, buildings, tunnels, access adits, etc.).
The breakdown of the duration of the contract is provided as follows:
• 2026-2032: studies, works and installations,
• 31.12.2032: commissioning,
• 2033-2039: maintenance of the established tranche,
• 2040-2047: maintenance of the optional tranches.
