Project Description
Contexte of the project
It will only take 26 minutes to travel from Nice Cote d’Azur Airport to the port in Nice via the city’s new 11.3km tramway with 20 stops.
Description of the project
The Nice Côte d’Azur Metropolitan Authority awarded the main civil engineering contract on the future line 2 of the tramway to the Thaumasia consortium.
Our solution
Soletanche Bachy France, working with Soletanche Bachy Tunnels and Bessac, alongside others within the Thaumasia joint venture, carried out surveys and civil engineering works for the 3.2km underground section under a contract involving a 9.8-metre-diameter bored tunnel, four underground stations, entrance and exit shafts, fittings and finishing, equipment, and testing. The tunnel is being built to efficiently serve the city centre while safeguarding its architectural heritage.
Soletanche Bachy faced the challenges of complex geology with highly variable soil and a small construction site in the centre of the city with shallow foundations and particularly sensitive built structures.
