Risk (possible changes in schedule): additional activities • Additional activities, especially those requiring supports from other groups can disorganize the global schedule, and induce delays. • CSCM tests in all sectors will cost around 4 weeks PT PT PT PT PT PT Warm-up Warm-up PT Warm-up Warm-up PT Warm-up Warm-up -> 10K Warm-up Cryo Maint.

Organization Reiner : “QPS upgrade and machine protection during LS1 ” Miguel : “Vacuum upgrade” Laurent: “Cryogenics system: strategy to achieve nominal performance and reliable operation “ • Schedule & logistics • Lots’of work still to be done in matter of schedule & logistics for all the other activities w.r.t. skeleton schedule • Preparation • ECR have to be written prior to works • Modification of the envelope of your equipment ICL • DIMR • Materials have to be ready in due time…..This has often induced delays !!! • Follow-up • Weekly coordination and scheduling meeting K. Foraz - LHC Performance Workshop 2012
Conclusions • Analysis of requests well advanced (LHC & experiments, injectors) • w.r.t. priorities & resources & time & interaction between groups • New requests will be scrutinized, especially the support form overloaded groups (VSC, EL, CV) • “Skeleton” schedules for LHC machine & injectors ready • Workload is huge and the schedule is tight • Worksites have to be well prepared.Please do not forget layout, integration & safety K.
