The object of the contract is an underground section of 2.8 km and four stations, one of them located at Praça da Liberdade very close to the historical city centre, which is a UNESCO World Heritage Site.

Porto light rail system, in operation since 2002, links seven municipalities of the Porto Metropolitan Area with Pedras Rubras international airport. Annually, it moves about 55 million passengers in its four lines, with a total length of 67 km and 71 stations, 14 of them underground, and having 7 km of tunnels.

In 1994, Sener led the joint venture in charge for the management of the technical assistance provided to Metro do Porto. The company carried out the preliminary studies, the election of the system, the preliminary design and the technical specifications, the evaluation of contractors' bids and the subsequent negotiation with the shortlisted firms, the monitoring and review of the detailed designs, the project management, the tunnel construction and the commissioning of the line. It also advised Metro do Porto in matters related to the system certification process.

Between 2006 and 2010, Sener also participated in the monitoring of the operation and maintenance of the entire metro network and was awarded the contract to develop the technical assistance for the second construction phase of this metro project.
