Abstract
The official groundbreaking of the civil engineering (CE) work for the high luminosity upgrade of the LHC started on15 June 2018 parallel to LHC beam operation. Compactorwork and shaft excavation around the two low beta experi-ments, ATLAS and CMS, were expected to induce vibrationsto the accelerator magnets and cause orbit disturbance, beamloss and potentially premature beam dumps. Ground motionsensors were installed on the surface and close to the triplets,where the CE works were expected to have the largest impacton the beams. This paper discusses the observations madeon the LHC beams that could be correlated to CE work.
