The European Laboratory of Particle Physics (CERN) has awarded the joint venture between Implenia (60%)/Baresel GmbH (40%) for a construction project to build several underground structures as well as various surface buildings in the French town of Cessy, around 15 kms from Meyrin (GE). This new infrastructure is required for CERN’s flagship upgrade project, the High Luminosity LHC. The contract is worth EUR 58 million. The joint venture is building an underground network of tunnels connected to the existing tunnels at CERN’s Large Hadron Collider (LHC). Access to the tunnels is provided by a new 60-m deep shaft, at the foot of which a cavern is being created for technical infrastructure installations. The joint venture is also building an underground power converter gallery, service tunnels and personnel safety exits. Visit https://www.implenia.com. 17/18.
