In the framework of the Radiation to Electronics (R2E) project, important mitigation actions are being implemented in the LHC during the first Long Shutdown (LS1) to reduce the Single Event Error (SEE) occurrence in standard electronics present in much of the equipment installed in LHC underground areas. Recent simulations have motivated additional actions to be performed in Point 4, in addition to those already scheduled in Points 1, 5, 7 and 8. This paper presents the organisation process

It reports the challenges linked to civil engineering and to safe room relocation in Points 5 and 7. It highlights the reactivity needed to face the new mitigation requirements to be implemented in Point 4 before the end of LS1. It presents the advancement status of the R2E mitigation activities in the different LHC points with the main concerns and impact with the overall LHC LS1 planning.
