High requirements for settlements due to historical monuments

Florence HSR link is strongly characterised by three functional components: the Rifredi interchange, the twin tunnels and the new Belfiore station. In more detail, the interchange was designed to allow an effective traffic management, avoiding problematic interferences between the new line and the existing historical tracks. The twin tunnels, with a total length of 5.1km, have an external diameter of 9.1m and reach a maximum depth of 27m. Finally, the new station was conceived to become an iconic landmark for the city (architectural design by Norman Foster).

The client was particularly concerned regarding potential problems that tunnel excavation could induce in the incredible number of wonderful historical masterpieces at the ground level. For the effective post-processing of the massive amount of collected excavation data, a specific web platform for monitoring was developed with Pizzi Terra.
