THE company building the driverless Grand Paris Express metro around the French capital, Société du Grand Paris (SGP), has announced the award of a €2.7bn contract to design and build the 14km western section of Line 15 from Saint-Cloud to La Défense.

The contract has been awarded to the Intencités 15 consortium led by Vinci Construction Grands Projets. It is the first to be let by SGP that combines design and construction of new metro infrastructure.

The members of the Intencités 15 consortium are:

  • Vinci Construction Grands Projets (lead)
  • Chantiers Modernes Construction
  • Razel-Bec
  • Dodin Campenon Bernard
  • SDEL Infi
  • Fayat Energie Services
  • ETF
  • Ingérop
  • Artelia
  • JFS Architectes
  • Grimshaw
  • Arep Architectes
  • Archi 5 Prod, and
  • Philippe Gazeau Architecte.

The contract includes the construction of five stations at Saint-Cloud, Rueil-Suresnes Mont Valérien, Nanterre La Boule, Nanterre La Folie and La Défense.

There will be interchange with lines L and U of the Transilien suburban network at Saint-Cloud and La Défense, with RER Line E at Nanterre La Folie, and with RER lines A and E, metro Line 1 and light rail route T2 at La Défense.

The 14km section between Saint-Cloud and La Défense is due to enter service at the end of 2031. Vinci says that it has made ambitious carbon reduction commitments under the contract with SGP, which will see the use of mostly low-carbon concrete on the project.

SGP says that 20% of the total contract value of €2.7bn will go to local SMEs. The Intencités 15 consortium will employ over 2000 people at the peak of construction and will create 460 posts for new entrants as it executes the contract, representing 10% of total work hours.

Tendering is still in progress for the three remaining Line 15 construction contracts, comprising the second lot of works on the western section and work on the eastern section which has been divided into two lots.
