Executive Project of the Fortaleza Metro (Brazil)

SENER provides 24/7 technical assistance for the Ferreira-Guedes-Sacyr Consortium for the excavation of the tunnel boring machines in the city of Fortaleza, in order to reduce the risks associated with excavation (to third parties, in terms of costs and time).

The project consists of building the east line of the Fortaleza Metro by using tunnel boring machines to excavate two tunnels approximately 7 m in diameter, with a length of 6 km each.

Executive Project of Phase 1 of the East Line of the Fortaleza metro includes:

• Execution of the Underground Work of the tunnels using TBMs, from the shaft after the Chico da Silva Station to the Papicu Station, and a section after the Papicu trench to park the TBMs;
