Cables & Fibres 34  But there are limits to the increase of manpower:  Lack of experience  Increase of manpower of contractors  CERN access, hotels, logistics bottle neck, Base vie?  Schedule/coactivity 12 Juin 2012LS1 Day - François Duval EN-EL

35  LS1 will be a very huge shutdown also for EN/EL  On the HV & LV infrastructure side, The program will be done with some additional resources  On the cables & fibres side, the situation is critical: prioritization is done but the effort is huge for the section in charge. Additional resources have been deployed from other departments: more are needed.  We are worried about the flow of requests which are still popping up in or elsewhere 12 Juin 2012LS1 Day - François Duval EN-EL EN/EL activities during LS1: Conclusion
