Greece’s state-owned subway operator, Attiko Metro, has short-listed three interested groups of contractors in a tender for a 1.5 billion euro ($1.8 billion) expansion project.
The bidders are Greek contractor GEK Terna with France’s Vinci and Germany’s Siemens; J&P Avax with Italy’s Ghella and France’s Alstom Transport; and Greek construction firm Aktor with Spain’s Ansaldo and Hitachi Rail Italy.
The three suitors have been asked to table their financial and technical offers by December 10 so that the selection process can begin.
The construction period for the project is eight years.
The Athens metro’s planned Line 4, known also as the U line due to its shape on the map, will start from Galatsi, head south to the city center and then northeast to Goudi.
It includes 15 stations and 12.8 kilometers of tunnels, while the concession project will also include the construction of two more buildings at Sepolia.
