Excavation of tunnel construction pit completed

05.05.2020 - Notes

The FAIR project has reached an important milestone: the excavation of the tunnel pit has been completed. At the end of April, the excavators shovelled the last soil out of the seventh and final excavation pit, thus reconnecting with the beginning of the tunnel of the underground accelerator ring, almost 1,100 metres long.

The excavation work began in June 2017 and the first excavation pit was handed over in May 2018 to the construction company responsible for erecting the structural shell. As soon as the floor slab, walls and ceiling of the tunnel are built, it will be filled in again step-by-step until eventually, only the exit buildings are visible.
