Status of infrastructure installations for HL-LHC
Following the handover of the civil engineering buildings and structures in the period from May 2020 until January 2023, the installation of the general services and technical infrastructures has started at the HL-LHC worksites of P1 (ATLAS) and P5 (CMS).
Update on Civil Engineering Work for HL-LHC
The two civil-engineering contractors, MARTI for the Point 1 works and IMPLENIA for the Point 5 works, are fully mobilized. The excavations of the shafts at Points 1 and 5 were completed in February 2019 and December 2018, respectively.
COVID-19 Impact on Schedule and Update on Civil Engineering Works
The COVID-19 restrictions have impacted the schedules of the LS2 and of the HL-LHC activities. Concerning the LS2 schedule, the hardware commissioning of LHC should be completed by March 2021 for all sectors except the S67.
Status of civil engineering works
In spite of the perturbation related to the COVID-19 pandemic, the civil engineering works is progressing well.
Status of civil engineering works and technical infrastructures
The civil engineering works is progressing well. The underground works, including the metallic structures, have been fully completed at Point 1 in October 2021 and Point 5 in February 2022.
