The opening ceremony of the northern extension of line 14 took place last week, in the presence of Prime Minister Jean Castex and the authorities. Thanks to its branch in France, I.CO.P. S.p.A. Società Benefit took part in this great project by implementing its specific high-tech know-how.
A large soil freezing operation using the combined method enabled the construction of a main underground structure at the Clichy Saint-Ouen station, allowing the excavation under the RER C line on service and the link between the southern tunnel lot T03 and the northern tunnel Lot T02.
The ICOP’s teams deployed all know-how to successfully complete a technically very complex operation in a very dense urban context with the RER C railway line kept in service above the excavation during freezing.
ICOP would like to thank the client RATP, the engineering supervisor SYSTRA and the VINCI-SPIE BATIGNOLLES joint venture who trusted us in a spirit of collaboration.
