Thirty major projects were announced in 2023, continuing the upward trend in construction.

Now, approaching the end of the year, we can see which projects these were and which companies attracted them. Almost all of the projects remain under auction, while there is also one project that has been signed.

Out of the thirty projects, the only one currently under construction is the trio of hospitals in Komotini, Thessaloniki, and Sparta, donated by the Stavros Niarchos Foundation. The contractor is ABAX, with a cost reaching 442 million euros.

However, what are these projects? We will categorize them into Metro projects, road projects, waste management facilities, buildings, flood protection projects, and irrigation projects.The total cost of our projects amounts to over 2.5 billion euros.

Metro Projects

Here we have two projects related to the Metro. The first one is construction-related and involves the extension of Line 2 to Ilion.The cost of the project, including VAT, amounts to 680 million euros, and the competition that started on May 3rd this year, with the expression of interest, attracted a total of 4 teams: ΤΕRΝΑ, ΙΝΤRΑΚΑΤ, ΑVAX-GHELLA-ALSTOM και ΑΚΤOR-ΜΥΤΙLINEOS.At this stage, the environmental approval processes are being completed, and the folders of the participants are being reviewed to determine who will proceed to the second round.

The second project is not construction-related; it involves the operation and maintenance of the Thessaloniki Metro.The competition also started in early 2023. The contractor is the Italian-French consortium THEMΑ (composed of ATM and EGIS), which won the 11-year contract with a total financial value of 250 million euros. THEMΑ is one of the leading companies in the European and international scene when it comes to metro network management.The contract follows the Public-Private Partnership (PPP) model. Both competitions were organized by the Hellenic Metro.
