Geotunel is participating in the expansion of the Porto metro system on the yellow line from Santo Ovidio to Vila do Conde and in construction of the new pink or circular line that connects Liberdade/Sao Bento with Casa de Música/Boavista, executed by Ferrovial S.A. and ACA Engenharia &Construção for the Metro do Porto public corporation.
Geotunel’s participation in the yellow line includes execution of the tunnel section using conventional mining methods from kp 0+765 to kp 1+605 and excavation of the shaft, with underground access and cavern widening, where the Manuel Leao station will be located.
Geotunel is performing the works for the San Antonio Hospital station on the circular (pink) line including emergency shafts and elevators, the Cais and Mezanino station caverns and the Poente and Nascente accesses. We are also working on ventilation shaft 1 and the tunnel section between San Antonio station and the future Liberdade station.
All these works represent a technical challenge due to working not only with the usual constraints of an underground project in an urban environment but also with the demands posed by the historical value of the buildings under which the route in question passes.
