13th of November 2012 Third LHC Splice Review 94 Persons 52 are at CERN 41 are trained and (very) experienced 9 are under training, 2 are at CERN but not available yet 42 have to be hired (on-going) Arrival between 6 weeks (goal) and 4 months prior to start of intervention Budget is foreseen For training, integration, qualification Normally for the entire duration of the project (Rotation exists) Training to be ensured in parallel with the work in the tunnel Is “local” recruitment being saturated ? [About 100 for the whole CERN] 69 Persons 45 are experienced (and are training newcomers) 6 are under training 18 are foreseen but are working on other activities (LHC operation for example) Part time availability from January 2013 on For training, integration, qualification FTE equivalent: in fact more persons available but partially Part time availability (Typically 40-50%) Training and know-how transfer have to be ensured in parallel with the work in the tunnel CERN staff SMACC Human resources availability FSU / Industrial Support + 18 persons as contractors (Leak test, weld inspection) 9/25 J.Ph. Tock

SMACC Human resources Training status 13th of November 2012 Third LHC Splice Review Persons are not at CERN 69 Collaborators Amongst them, 26 are experienced 43 remains 42 FSUs Persons are not available 2 FSUs 19 CERN staff (FTE eq) Typically 35 persons Why not more training ? “New” resources towards task with a short training period (Ex: Open/Close IC) Error proof “automatic” procedures (Ex ELQC) Tooling sent to collaborators (Ex cutting machine) so pre training Revival of previous teams (ELQA, ICIT) Low ratio for splices, due to new activities and recent resizing of the teams following mock-up tests (Insulation, shunt soldering, cu machining, QDiodes) Detailed procedures Good ratio easier to ensure for small teams 10/25 J.Ph. Tock

SMACC Human resources 13th of November 2012 Third LHC Splice Review Safety Motivation Coordination Team work Competent and equipped The only way to success 11/25 J.Ph. Tock
12
SMACC Budget 34.5 MCHF 13th of November 2012 Third LHC Splice Review Human resources oriented project (71%) (Almost) no contingency 45 % for splices consolidation proper From sleeve machining to rewelding (excl QA) 23 % for QA/QC outside production teams Rest for: Giving access and reclosure (11%) Specific consolidation (13%) Logistics, management, others Budget structure put in place (12 budget codes) 12/25 J.Ph. Tock

SMACC Budget Time evolution 13th of November 2012 Third LHC Splice Review Material budget spent before start of the work Remains maintenance, logistics, consumables Means oriented expenditures What matters: Quality Deviations Progress rate 13/25 J.Ph. Tock
14
Contingencies 13th of November 2012 Third LHC Splice Review How to cope with : Unforeseen developments ? > 15 % of splices to redo New non-conformities … Unforeseen scenarios ? Contingencies in available man power Sizing the team for 60 IC/week eq and planning assumes 53 [13 %] 6 efficient working hours are assumed (2 hours for displacement) [Realistic – 0%] No work planned on weekends : Limited impact because of legal limitations Limited experienced and trained staff available Some experienced staffs are presently not in SMACC. In case of need and priority given by management, they could be redirected to SMACC. [5%] Staff collaboration profile [A few %] In manpower In the SIT In the schedule In the budget (Almost none) Training Overlap and know-how transfer “Realistic”? workload profile Start-up issues Contingency ? (schedule delays ) 14/25 J.Ph. Tock
15
13th of November 2012 Third LHC Splice Review Increase of Special Intervention Team capacity Outsource standard interventions (Opening, closure, main BB soldering, ….) to the train team [Gain of expertise] Increase its size : + 3 persons (20% increase) This ensures a theoretical (optimistic) availability of minimum 30 % to handle NCs and full (theoretical) availability for the last 6 months Courtesy N Bourcey / M Bernardini Contingencies In manpower In the SIT In the schedule In the budget (Almost none) 15/25 J.Ph. Tock
16
13th of November 2012 Third LHC Splice Review Contingencies In manpower In the SIT In the schedule In the budget (Almost none) Contingencies in the LS1 schedule ? Sizing the team for 60 IC/week eq and planning assumes 53 [13 %] SMACC is on the critical path (See K Foraz’s presentation) Looking by sectors, there are some margins (Are they real ?) beware of coactivity, access constraints and limitations of other resources 16/25 J.Ph. Tock
17
13th of November 2012 Third LHC Splice Review Contingencies after CD are not usable if < 3 months (Warm-up & Cool-down durations) These periods are used by other teams so there will be access constraints (Powering test, pressure tests,….) and coactivity Shifting some sectors would increase parallelism of subsequent activities with obviously also limited resources so would impact on the overall schedule 3 last sectors without usable time slot If issue detected after CD, interventions can be envisaged in only 2 sectors (67/78) with a limited but non negligible impact For 56 (the first one), there is a possibility to correct if the issue is/can be identified before cool-down Using these contingencies would greatly impact the whole LS1 (ALMOST) NO CONTINGENCY IN THE LS1 SCHEDULE Contingencies In manpower In the SIT In the schedule In the budget (Almost none) 17/25 J.Ph. Tock [months]
18
13th of November 2012 Third LHC Splice Review Time windows are foreseen in the detailed schedule for unsoldering and resoldering all splices [Baseline is 15 %] Corresponding teams are slightly oversized wrt 15% Tooling is available Contingencies In manpower In the SIT In the schedule In the budget (Almost none) 18/25 J.Ph. Tock

13th of November 2012 Third LHC Splice Review SMACC Organisation concerns: Schedule Manpower Technical Logistics First sector validated 15 months after start, Too late for feedback -Thorough beforehand testing and reviews -Training -Qualification -Intermediate QA/QC SMACC Train will extend on 3 sectors SMACC will extend on the 8 sectors Supervision will be an issue -Reduces coactivity -Worksite coordinator -Logistics foreseen +Cars and equipped trucks, +Canteen, storage, meeting rooms on the points 19/25 J.Ph. Tock
20
13th of November 2012 Third LHC Splice Review SMACC Organisation concerns Schedule Manpower Technical Logistics Availability Collaboration agreements to finalise Potential difficulty in FSU recruitments Staff turnover Planned for collaboration Short notice with FSU Ratio of experienced staff -Training is planned -But will have to be simultaneous to work in the tunnel -Detailed procedures -Overlaps ? Can we do more ? 20/25 J.Ph. Tock
21
13th of November 2012 Third LHC Splice Review SMACC Organisation concerns Schedule Manpower Technical Logistics DFBA consolidation Technical solutions still under development Could impact the overall schedule and divert critical resources Newly discovered NC Beam operation so far has only identified a few new issues Experience shows that there will be many ? How Critical is it? ? Are available contingencies sufficient ? ? Can we do more ? 21/25 J.Ph. Tock
22
13th of November 2012 Third LHC Splice Review SMACC Organisation concerns Schedule Manpower Technical Logistics Access modalities Relaxation of access constraints (No biometry) What will be the next bottleneck ? Lifts ? Solution for bikes under study General logistics Efficient logistics for RP vacuum cleaners handling Parking places shortage Shuttle services ? How Critical is it? ? Can we do more ? 22/25 J.Ph. Tock
23
13th of November 2012 Third LHC Splice Review SMACC Organisation concerns Schedule Manpower Technical Other From my “little” experience, most things happen... And many more… 23/25 J.Ph. Tock
24
13th of November 2012 Third LHC Splice Review SMACC Organisation Conclusions Schedule Optimised baseline is available for LS1 and SMACC in particular No global contingency / Some little local ones included Manpower Ratio of experienced staff is about 50 % thanks to Advanced hiring of FSU and training Reintegration of experienced collaborators Turnover to be minimised To be finalised (FSU, collaboration agreements) Technical DFBA consolidation is late wrt other activities Logistics Actions are taken to avoid bottlenecks We are not ready YET but we are confident that we will be ready for the start of the interventions in April 2013 Continuous efforts, commitments and works are required 24/25 J.Ph.
