The Greek Tunnelling Society Young Members, in collaboration with ATTIKO METRO, organized a technical site visit to the tunnel of the GNA Station on Metro Line 4A. This visit offered our new members a unique opportunity to witness first-hand the development of a major infrastructure project in full progress.

During the visit, participants toured the construction site and observed real-time support works, gaining valuable technical insights and practical experience.

A special thank you to Kostas Kondylis and the project engineers from AVAX, Mr. Georgios Mavrodakos and Mr. Nikos Georgaras, for their guidance, support, and for sharing their expertise throughout the visit. We also sincerely thank Mr. Georgios Stoumpos, Mr. Evangelos Pergantis, and Mr. Dimitrios Alifragkis for their key contributions in making this visit a reality.
