Some other projects are linked to the CV consolidation plan. Finally, most of the work shall be done to respond to several requests: SR buildings air conditioning, the need to be able to clean and maintain the LHC cooling towers without a complete stop of cooling circuits, the upgrade of the air conditioning of the CCC rack room cooling etc. For all these activities , the author will detail constraints and the impact on the schedule and on the operation of the plants that will however need to run for the major part of the shutdown.
