How is a mountain excavated? What jobs lay behind the construction of a 53-km-long railway line? What skills are required?

To explain this, we created a HowWebuild video series, a six-part tech series that chronicles the Terzo Valico dei Giovi construction site from the inside, analysing the progress of the work and delving into its various facets with our colleagues working on it.

Let's discover together the construction techniques of the Terzo Valico dei Giovi – Genoa Junction One Project, a large infrastructure which will allow trains to travel at a maximum speed of 250 km/h, crossing the provinces of Genoa and Alessandria, involving 12 municipalities, until reaching Milan.
