Focus on the Mont Cenis base tunnel works in France and in Italy and on above-ground works.
Let’s take stock of how the excavation materials between Chiomonte, Salbertrand and Susa are processed
The new TBM has been started by the French and Italian Ministers of transports Philippe Tabarot and Matteo Salvini.
Work is progressing on the railway viaduct over the Arvan, the Chiomonte junction on the A32 and the new San Didero car and truck terminal.
Together with its twin TBM it will cross the border between France and Italy.
The contract for the management of excavated materials in Italy was awarded to five companies from Piedmont and one from Switzerland.
The gripper tunneling machine was delivered on Thursday 21 December at the Herrenknecht factory in Germany.
The companies of the UXT consortium, led by Itinera, signed the Sustainability and Security Pacts with TELT.
On 6 October, the group of companies together with TELT were present at the test of the machine at the Herrenknecht factory in Germany.
The contract worth EUR 1 billion was awarded to the binational group of companies composed by Itinera (agent), Spie Batignolles and Ghella.
The binational public promoter with the companies on the construction site witnessed the trials of the machine that will excavate the next 9 km beneath Mont Cenis.
SNCF has awarded the tender for the above-ground works between the Lyon-Turin base tunnel and the historic line.
At Saint-Julien-Montdenis, work began on the French entrance of the Mont Cenis base tunnel.
With the 10.5 km base tunnel completed on time and on budget TELT presents Mission-S, the programme to improve safety at work.
The CIM 4.0 competence centre has created for Webuild the first autonomously-guided robot to safely explore the deepest area of the gallery.
Mission-S: TELT and companies sign pact for accident prevention and workers’ health
At Saint-Martin-la-Porte, in a stretch of the mountain particularly difficult, two fronts are advancing with caution using traditional methods.
The contract concerns the construction of four vertical shafts to be excavated from the foot of the Villarodin-Bourget / Modane access tunnel.
The excavation of the first 9 km of the Turin-Lyon base tunnel has ended: the “Federica” boring machine has now broken down the last section of rock and has completed the first phase of the great European infrastructure.
