      Construction management

      As part of the road tunnel Safety measures, in accordance with Circular 2000-63, DIRIF has entrusted INGEROP for design and work supervision for the safety of the Champigny sur Marne cut-and-cover tunnel. This mission follows the definition of the improvement programme and elements of the Safety Dossier in 2003-2004.

      • Works with maintenance of the operation
      • Co-activity with 4 other transverse construction management on the site (supervision overhaul, DAI video and physical closures, self-evacuation, radio, etc.)

       

      Civil engineering works:

      • Emergency exits and new safety and fire niches creation
      • Facilities for disabled people
      • N2 or N3 fire protection of structures and networks
      • Redevelopment of technical rooms and ventilation plants

       

      Equipment works:

      • Resumption of High Voltage (HTA) distribution (new HTA link between substations), refurbishment of technical premises with modification of HTA switchboards and securing of Low Voltage.
      • Renovation of the ventilation system (longitudinal system with accelerators in the south and semi-crosswise in the north)
      • Complete overhaul of the lighting installations in the 2 tubes and installation of beaconing studs
      • Redesign of the fire network

       

      SIRIUS network routing

      Complete overhaul of the Centralised Control Management (CTM), interfacing with the general overhaul programme for the supervision of the 22 Ile-de-France tunnels

            The cross-border section of the Lyon-Turino railway line is a new railway line of about 67 km linking Saint Jean de Maurienne in France to Suze in Italy and Bussoleno where it connects to the historic Turino-Modane line. In particular, the line requires the excavation of a 57.5 km single-track twin-tube tunnel known as the “Montcenis base tunnel”.

            On the French side, the civil engineering of the base tunnel is divided into 3 operational worksites.

            The construction management of the 08-operating site, led by a consortium formed by Egis tunnels (leader)/ Ingérop/Alpina/Géodata, includes the construction of the following works:

            • The construction of a site platform at Villard Clément at the head of the future French side
            • Preparatory construction for access to the future tunnel head (high-level temporary lining, mass earthworks, special ground reinforcement work),
            • Excavation and lining of the two tubes of the base tunnel and the linking galleries over about 3 km,
            • The construction of a cut-and-cover tunnel about 140 m long at the connection between the entrance to the base tunnel and the cut-and-cover tunnel under the A43 motorway already constructed as part of another construction package,
            • The construction of the networks and water drainage system at the tunnel exit, the backfilling and definitive site installations

             

            Characteristics

            • Multiple interfaces work with the existing (buildings, infrastructures, networks) and other construction sites of the project (construction civil engineering sites, processing of excavated materials)
            • Carrying out additional geotechnical and topographical studies, ICPE (Classified facilities for Environmental protection) files

                The Chilterns Tunnel is a 15.8km bored tunnel. There will be four vent shafts and one intervention shaft located along the proposed line of route – Chalfont St Peter, Chalfont St Giles, Amersham, Little Missenden and Chesham Road. Its southern portal is located near Maple Cross. Its site will also house a compound during construction with all material from the bored tunnel coming here to be treated prior to being used elsewhere along the line of route. The northern portal is adjacent to South Heath.
