French rail organisation seeks shaft solution partner

French rail infrastructure operator SNCF Réseau has started the search for a contractor to construct an emergency access shaft for the Meudon Tunnel on RER Line C from Invalides to Versailles Rive Gauche.

The launch of the pre-qualification process for construction of the 40m deep, 8m diameter evacuation shaft was announced in the Official Journal of the European Union.

The work will also include construction of a 46m long connection tunnel.

The 3.36km long tunnel was built in the late 1890s but was declared dangerous by the L’Office parlementaire d’évaluation des choix scientifiques et technologiques in 2010, which was launched an investigation following the Mont-Blanc Tunnel accident in 1999, due to fire safety issues and lack of emergency access at Meudon.

The pre-qualification process will end on 27 April and a shortlist of tenderers will be announced in mid-May.
