Under the €438m contract, the consortium will bore 6.7km of tunnel between the Saint-Quentin Est and Versailles-Chantiers stations in western Paris. The work, scheduled to take 104 months, also includes building three stations and eight ancillary infrastructures.
Challenges on the contract include tunnelling through the Fontainebleau sands, and in close proximity to the SNCF railway line at Versailles.
The Grand Paris Express, described as Europe’s largest sustainable mobility initiative, will extend the French capital’s metro and light rail network by 200km, with 68 stations, to improve connections between the city centre and the periphery.
Ferrovial says the contract strengthens its footprint in France. The company has been operating in France since 2013, having executed four contracts in ITER, the world’s largest experimental fusion facility.
