Will there be any long-term environmental impact?
Will there be any long-term environmental impact? Road traffic will not be affected. When the work is complete, the footpath in Meyrin linking the Maisonnex sports complex to the Chemin de la Berne will be reopened, with the route modified to pass around the new buildings. The footpath in Cessy will remain unchanged. Both sites

How did the work affect the environment?
How did the work affect the environment? The contracts concluded with the two civil engineering consortia imposed environmental restrictions and, notably, the hiring of experts to perform environmental monitoring on the worksite. The noise generated by the work was limited to respect French and Swiss regulations. An acoustic system monitored noise levels at various times.

How will the work affect traffic?
How will the work affect traffic? During the excavation period, lorries will transport the spoil to treatment or storage centres. A maximum of 10 lorries will come and go on the Meyrin site each day, and 10 to 15 on the Cessy site. Spoil will be transported only during working days (Monday to Friday) and,

What will happen to the excavated spoil?
What will happen to the excavated spoil? In total, 92,000m3 of spoil were excavated from the underground structures on both sites. The excavated material was analysed on the surface to check its quality and the spoil polluted by hydrocarbon was managed accordingly. On the Meyrin site, much of the excavated material will be reused to

What was the work schedule?
What was the work schedule? The HL-LHC civil engineering works began in May 2018 and lasted five years. All foreseen underground and surface works were successfully completed in September 2022 at Point 1 and in December 2022 at Point 5. Related articles

Who carried out the work?
Who carried out the work? The HL-LHC civil engineering project is based on four main contracts. Two consultancy service contracts are dedicated to the design and to the construction administration: SETEC–CSD–ROCKSOIL (ORIGIN) at Point 1 and LOMBARDI–ARTELIA–PINI (LAP) at Point 5. Two supply contracts are dedicated to the construction of both the underground and surface

What civil engineering work was required for the High-Luminosity LHC?
What civil engineering work was required for the High-Luminosity LHC? The new equipment for the High-Luminosity LHC requires new large civil engineering structures on the sites of the ATLAS experiment in Meyrin, Switzerland (LHC Point 1) and the CMS experiment in Cessy, France (LHC Point 5). On each site, the underground constructions consist of: –
