Tender documents for geophysical and geological consultancy services for a tunnel on the planned 65km Lyon to Turin railway have been published in the Official Journal of the European Union (OJEC).
Project promoter Tunnel Euralpin Lyon Turin (Telt) is calling for bidders to create a three year framework contract to support in its groundwater modelling work on the Italian end of the tunnelled section of the scheme.
The twin bore 57.5km Mont Ceris base tunnel is a key part of the planned rail link, which is considered the main missing link in the corridor which aims at connecting south western Europe with Central and Eastern European Countries. The tunnel will cover 45km in France and 12km in Otaly and include 170 connection tunnels, four intermediate access shafts, five ventilation shafts and three underground security areas.
Preliminary tunnelling work has started with three access tunnels completed in France and another in Italy. Another 9km tunnel is currently being excavated using a tunnel boring machine in order to gain insight into the geology of one of the most complex section of the tunnel using the same diameter and on the planned alignment of the tunnel.
Tenders for the groundwater study must submit their documents by 6 October.
