Normal conducting accelerating structures are used up to 92 MeV and superconducting structures up to 2 GeV. Most linac components are designed and procured as in-kind contributions by institutes/laboratories in the European partner countries. Installation of the Ion source delivered by INFN-Catania started end 2017. Installation of more components and infrastructure progresses at a high pace. Commissioning of the normal conducting linac section will take place in parallel with installation of the superconducting section. Beam commissioning of the superconducting section will be done starting in 2021, interlaced with the installation of additional high beta cryomodules. Beam will be sent to the target in 2022, initially at an energy of 1.3 GeV. Start of the User Programme is scheduled in 2023, when some neutron instruments will be ready and end of construction is in 2025, with the full set of instruments operational. This paper reports the status of linac components construction, the progress with installation on site, and the overall project schedule.
