Work: INVERTED VAULT AND CONCRETE WORKS IN DANES AND SIGHISOARA TUNNELS (ROMANIA) Client: JV FCC-Azvi-Alpine-Straco

Execution of the inverted vault and sidewalks is carried out simultaneously to the bench excavation into a cycle of scheduled activities. All concrete structures are reinforced with steel.

CIVILSUB teams develop steel works, both inside and outside the tunnel, as well as formwork and concreting. The cycle consists of an outside team making reinforced steel modules which are joined on site to its final position, to be finished by the team inside the tunnel. All works are performed in a closed 24-hour cycle.
