The presentation summaries the planned new underground civil engineering work for the HL-LHC upgrade project. The related work implies significant underground excavation work and studies were launched to study the impact of such underground work on the operation of the running LHC machine. The studies involved test drills, vibration excitations using shakers and the analysis of the impact of earthquakes on the LHC operation. The studies showed a beam sensitivity of up to 1micormeter and indicated that the HL-LHC excavation work would can not be conducted in parallel to the LHC operation and lead to a revised schedule and planning that foresees most of the civil engineering work during the Long Shutdown 2.
