Civil engineering works were distributed in eight contracts which were awarded after bidding by five companies: SNCF, ISL, Tractebel, Scétauroute and Setec. This is the first time there has been competition for the construction of a TGV line since reform of the rail system in 1997 and the involvement of RFF. SNCF Engineering, in partnership with EEG Simecsol succeeded in obtaining four of the contracts (including one for the second phase), this being 50% of the civil engineering project. Moreover, it directed the entire superstructure works project (track, signals and electrification) under the responsibility of Réseau Ferré de France.
