13. Access Systems – Special SMACC 13Ch. Delamare GS-ASE «James Bond» suitcase Specific development Used in some LHC points Easier access of the SMACC train Our opinion: useful system but not essential

14. Access Systems – Availability/flexibility Availability Very few incidents with the Access Systems MAD difficulties => remote operation by CSA Systems heavily solicited More maintenance Always difficult to find slots for maintenance “Swap”/juggling between the access points Typical use case: incident with lifts Flexibility well appreciated by EN-MEF Manual procedure for the LS1 14Ch. Delamare GS-ASE

15. Access Systems – Lessons learnt Two different contexts Large Project (owner) E.g. PS Access, LHC Access LS1 evolutions “Small” project workpackage E.g. SUSI Access Control (or Fire detection works) plan.cern.ch was essential Permitted to identify tens of coming requests Should come asap for LS2 Identify and analyze proposed evolutions asap (ECR) Point 7 Collimation: September 2012 Preparatory phase organized by EN-MEF well appreciated Integration (3D) laser scans, studies and conflict detections to pursue and reinforce Early detection of conflicts between key projects (and “big” items) E.g. PS Access & PS Cooling and Ventilation Develop and simplify publication and approval of 3D views Keep the notion of “LS1 mode” (Access Safety System “in reduced mode”) To be planned with BE DSO Ch. Delamare GS-ASE15

16. Access Systems – Lessons learnt Access conditions & Safety training A lot of newcomers – how to practice ? Safety Training Center ? Safety trainings (&DBs) must be in place much before the start of the LS CSA (guards) involvement Clear need: the integrity of the envelop MAD remote operation very useful to handle difficult cases Dedicated and trained “ZORA team” Coordination in LHC & injectors well appreciated Coordination in Meyrin Experimental areas – room for improvement Planning and stakeholders especially in commissioning phase Identification of the actors to operate infrastructure DSO tests are essential Allocate and “protect” the slots – huge commitment of several teams Works on some EIS-beam just before these tests Keep in mind the specific maintenance requirements of these equipment Validation, traceability, etc. 16Ch.

27. Mobility car fleet 27 167 additional LS1 cars 55 cars still in use as of end March CERN-wide fleet management required Anticipation of the needs Contractual solution(s) E.g. leased cars (but higher cost + VAT fuel) 1/2 Ch. Delamare GS-ASE

28. GS-IS LS2 forecasts Forecasts are needed for almost all GI-IS areas Budgets, service contracts Inform on quantity and quality change versus LS1 E.g through plan.cern.ch enhance activity details with data such as Required storage space Material needs Cleaning request Generated waste CERN Stores standard items Anticipate project needs to identify the best suppliers, prepare supply contracts, stock only the necessary level of material (no dead stock), respond at the right time to material demands. Infrastructure: New building for radioactive storage On-going process. Can take up to 3 years Please answer to the corresponding surveys (+regular updates) Ch. Delamare GS-ASE

36. Civil Engineering - LS1 - preparation LS1 activities started well before the shutdown Task force for the space requirements Involved long negotiations – time consuming Implied construction and transformation works before LS1 period started Identification of the support to be provided to equipment groups Plan tool as a starter Involved long discussions with equipment groups to anticipate requirements for CONTRACTS, RESOURCES and BUDGETS 36Ch. Delamare GS-ASE

37. LS1 – dedicated organization 37Ch. Delamare GS-ASE

38. Civil Engineering – Lessons learnt Allow sufficient time for preparation Many things GS-SE does are needed well before the beginning of the shutdown. Additional resources need to be on board well in anticipation (1 year!). Strategy of support contracts needs to be finalized NOW. Note that Civil Engineering large works require ~2-3 years from the decision to the realization (contract for design, design, building permits, contracts for works, works) Huge list already collected (e.g. Chamonix) Communicate at all level (internal/external to the group) Management of priorities (machine/tertiary) Quick decisions are needed to shift personnel from the standard services (e.g. leaking roof) to tunnel services (e.g. equipment supports) Time consuming participation to coordination meetings. 38Ch.
