Panama City Metro Line 1 

Initial Phase (Inauguration in 2014)

Sener accompanied the construction consortium in all phases of the Design & Build project, from technical assistance and preparation of technical documentation in the tender process, to detailed design, including technical assistance for construction. 

We elaborate the detailed design of the 7.1 km double-track tunnel and eight underground stations, including associated ventilation and emergency rescue shafts. In addition, we collaborated with the consortium on:

• Elaboration of the design basis: in coordination with the client, we prepared the design basis for all specialties, in addition to developing field work such as topography, geology, hydrological studies, etc. 
• Basic design of the project: identification and resolution of all design interfaces between all disciplines and the different parties involved. 
• Construction project: Sener carried out the construction project for the Panama Metro, including: 
  • 7.1 km in tunnel with TBM.
  • 8 underground stations.
  • Workshops and depots for a fleet of 26 trains, with a total area of 10 Ha.
  • Ventilation shafts and emergency exits.
  • Auxiliary systems.
  • Technical assistance to the construction under the D&B modality. 

The Panama Metro was conceived as a high-capacity mass transit system with conventional metro-type trains with steel wheels, composed of up to a maximum of 5 cars, for an approximate length of 91 m and 2.71 m wide at the waist, and with an estimated maximum capacity to transport 39,000 passengers per hour. 

Expansion: from San Isidro to Villa Zaita (inaugurated in 2024)

A 2.4 km extension located on the north side towards the Villa Zaita area, including a new station with this name, for which we have developed the tender, basic and detailed engineering of the civil works of the project. 

The project has an investment of more than 200 million euros and will allow an increasing of the traffic of the metro line by 30,000 passengers per day. 

At Sener we have been in charge of the: 

• Design of the route: an elevated section along its entire length, which is materialized on prestressed concrete beams up to 30 meters long. 
• Viaduct. 
• New elevated station at Villa Zaita (located above Avenida Transístmica, with a section that expands from two to three lanes in each direction). 
• Intermodal building (with a bus interchange with 16 bus platforms and two floors for a total of 600 parking spaces). 
• Pedestrian accesses and the extension of the avenue: the redevelopment of the surroundings of the track and the station has been developed, on a total area of about 13 hectares.  
• Management of interfaces with railway systems.
