ABSTRACT
The construction of Line C San Giovanni station in Rome required the adoption of building techniques suitable for responding to the numerous problems concerning geology, archaeology and the surrounding buildings. The procedures for building this station were heavily constrained by what emerged unexpectedly at the start of the work: the archaeological findings down to a depth of 18 m from ground level. The project faced logistical challenges, such as the underpassing of the existing Line A San Giovanni Station with two tunnels excavated by conventional mining using artificial ground freezing. The archaeological findings required an overall revision of the internal design of the station: at the end of the archaeological excavation, the Archaeological Ministerial Office required the contractor to change the interior design to safeguard these findings. Metro C designed a new architectural layout and San Giovanni station became the first archaeological station in Italy.
