	To increase by more than 10 times the luminosity reach w.r.t the first 10 years of the LHC lifetime, the HL-LHC project will replace nearly 1.2 km of the accelerator during the Long Shutdown 3 scheduled in 2024 [1][2][3]. This paper presents the HL-LHC alignment and internal metrology requirements of all the new components to be installed, from the magnet components to the beam instrumentation and vacuum devices. As for the LHC, a combination of Hydrostatic Levelling Sensors (HLS) and Wire Positioning Sensors (WPS) is proposed for the alignment of the main components, but on a longer distance (210 m instead of 50 m), generating technical challenges for the installation of the stretched wire and for the maintenance of the alignment systems. Innovative measurements methods and instrumentation are under study to perform the position monitoring inside a cryostat of cold masses and crab cavities, in a cold (2K) and radioactive (1 MGy/year) environment, as well as to carry remote measurements in the tunnel of the intermediary components. The proposed solutions concerning the determination of the position and the re-adjustment of the components are detailed in this paper.

	The Configuration and Layout (CL) team at CERN ensures that there is a clear and coherent representation of the status of the CERN underground facilities (about 60 km of equipment) and main accelerator projects at a given point in time. In view of the major equipment changes to be carried out during the extended end of year technical stop (EYETS), the next Long Shutdown (LS2), and to facilitate the associated preparatory work of multiple CERN groups, the CL team has developed an immersive visualisation tool, displaying 360 degree panoramic images of CERN underground facilities. In addition, the CL team is launching a process to manage future layout configurations inside the CERN Layout database in parallel to the current configuration. This paper presents the 360 degree panorama visualisation tool and the parallel configuration process, to view the past, current and future status of the CERN accelerator complex. It highlights their added value for the CERN groups in the preparatory phase for upgrade and consolidation modifications and discusses the potential future improvements.

The Configuration and Layout (CL) team at CERN ensures that there is a clear and coherent representation of the status of the CERN underground facilities (about 60 km of equipment) and main accelerator projects at a given point in time. In view of the major equipment changes to be carried out during the extended end of year technical stop (EYETS), the next Long Shutdown (LS2), and to facilitate the associated preparatory work of multiple CERN groups, the CL team has developed an immersive visualisation tool, displaying 360 degree panoramic images of CERN underground facilities. In addition, the CL team is launching a process to manage future layout configurations inside the CERN Layout database in parallel to the current configuration. This paper presents the 360 degree panorama visualisation tool and the parallel configuration process, to view the past, current and future status of the CERN accelerator complex. It highlights their added value for the CERN groups in the preparatory phase for upgrade and consolidation modifications and discusses the potential future improvements.
