WTC2023 Technical Visits

Technical visits for Congress attendees, as they attached below, will be held on Thursday 18th of May 2023.

Draft Program

of Technical Visits

Athens  Metro  Line 4  (A’ Phase)

The Contract Agreement was signed in June 2021 with an estimated cost of 1.5 bn. euros and 8 years of construction period. The first phase (from Alsos Veikou to Goudi) of the U-shaped Line 4 will serve densely populated districts of Athens. The Project comprises 15 underground stations, 9 shafts and approx. 13 km of running tunnels plus a new underground depot. The tour will visit several worksites to view tunnelling and underground construction works. There may be two options for visitors to choose between half-day or one-day tour according to number of sites to be visited.

The Hellinikon Project

The biggest project of its kind in Europe with 8 bn. euros of investment expanding at an area of 6 mil. m2 and the most ambitious development ever undertaken in Greece. It combines urban development, recreation facilities, a huge metropolitan park and seafront full accessible to the public. Access through metro and tram lines will be assured while the existing road along the shoreline will be reconstructed to become fully underground. Works started in summer 2020 and move forward rapidly. The tour will walk the delegates around the various worksites in the area as well as the underground coastal road.

Immersed Road Tunnel Salamina-Perama

 

The Project is in tender phase and construction is expected to begin in early 2023. The road tunnel will be an immersed double tube tunnel under a busy naval channel and in an area with archaeological interest. A half day tour will enable delegates to visit the worksite of the tunnel, watch the construction method and hear about the E/M and safety systems scheduled for the operation period.

Lavrion Underground Hazardous Waste Repository

 

The Lavrion Underground Hazardous Waste Repository was commissioned in 2009 as part of the restoration of the old “French Company of Lavrion Mines” facilities. It is designed to store approx. 5000 tn of hazardous waste with high concentrations of heavy metals and toxic metalloids. The repository was constructed under low overburden using the room and pillar mining technique. The total area of the repository is 2,475 m2 and is accessible through an inclined tunnel and a 35 m deep shaft. The Repository visit can continue with a tour of the restored old metallurgical facilities which were rescued and given to the student and the local communities as a technology plus culture centre.

New Road Tunnels in Metropolitan Area of Athens

 

New urban road tunnels are planned in the metropolitan area of Athens. One of them is the Kimis tunnel which will connect Attiki Odos with the Athens-Thessaloniki motorway. It will be a 2.1 Km long double tube tunnel and the Project is in tender phase. It is expected that tunnelling works may be underway by 2023 and a technical visit will be quite interesting for the WTC 2023 attendees.
