  31. Cables & Fibres The LS1 Project Leader decided • requirements/resources LS1 Day - François Duval EN-EL

  32. Cables & Fibres • Additional resources • AGH (12 project associates from Krakow) • Fellows & associates (+10 in 2011/2012) • 2 installation contracts (doubled manpower) • FSU being prepared • Specialists + project managers required (skilled and experienced people) LS1 Day - François Duval EN-EL

  33. Cables & Fibres • Help from other departments & experiments We still want new people working with EL team in order to have coherent works done • Work supervisors • Knowledge and experience of cable laying or fibre blowing technologies • Experience in work site supervision • Knowledge of site works • Project managers • Project management • People management • Schedule & Budget management • Knowledge of dedicated softwares(GESMAR, Câblothèque) LS1 Day - François Duval EN-EL

  34. Cables & Fibres • 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 LS1 Day - François Duval EN-EL

  35. EN/EL activities during LS1: Conclusion • 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 PLAN@CERN or elsewhere LS1 Day - François Duval EN-EL
