The construction of Venezia station of Rome Line C Underground presents a significant engineering challenge within an archaeological and monumental context. The civil works will begin with the excavation of an 85 m long diaphragm wall, after which the archaeological investigation will be carried out to a depth of 15 m, before the construction of the cross walls to reduce the deformability effects. The complex geological conditions necessitated for the ground freezing technology for the tunnel excavation. Geotechnical and structural analyses have been conducted to study the potential effects of the excavation on the monuments leading to the design geotechnical and structural interventions for their protection. At the end of the excavation, some of the archaeological structures discovered will be relocated to the atrium of the station that will represent a unique ensemble with the museums of Venezia Palace, the Vittoriano, and the Roman Forum.
