TOULOUSE public transport operator Tisséo has awarded a consortium of Eiffage and NGE a second contract to undertake civil engineering works on tunnels, stations and structures for Line C, the French city’s third metro line.

The €233m contract covers Lot 1 of the project, from a point 100m from Colomiers Gare station to Laporte, with Eiffage having a 65% share in the contract and NGE 35%. The consortium, which is represented by Eiffage through its Eiffage Génie Civil subsidiary,will in this contract be responsible for constructing a 3.85km tunnel, three stations, four inter-station ancillary structures and three passages connecting the tunnel to access shafts. The three stations are to be named Colomiers Gare, Airbus Colomiers and Airbus Saint-Martin.

Earlier this month Tisséo awarded the consortium the €590m Lot 2 contract for civil engineering works on the Laporte - Raynal section of Line C, including an 8.4km main tunnel. The contract also involved construction of six stations, to be named Ouvrage Laporte, Jean Maga, Sept Deniers, Fondeyre, La Vache and Toulouse-Lautrec.

Work on Lot 1 is expected to begin this spring following a three-month preparatory period. The same methods involving “next generation” TBMs, fibre-reinforced concrete segments manufactured at the consortium’s own plant near Toulouse and Eiffage’s Carasol soil analysis techniques will be deployed as on Lot 2. The consortium says it will take special measures to minimise the impact of construction work on local communities and aims to recover 80% of the excavated material.

The project will provide employment for up to 550 people, including 70,000 hours under access to employment programmes in which training will account for 20% of the total. In all, around 150 to 200 new jobs will be created.

Handover of the completed infrastructure is expected in summer 2027, followed by equipment installation work prior to commissioning in 2028.
