Ch. Delamare GS-ASE
Persons in LHC – Sept. 2014 – March 2015
13
Access Systems – Special SMACC
Ch. 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

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
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

• 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

Ch. Delamare GS-ASE
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
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.Ch. Delamare GS-ASE

List the different aspects in the management of the work carried out during the LS1
Define what should be kept and was an added value during the LS1

Define what was a bottleneck to carry out the work during the LS1 and needs to be changed for LS2
3D Integration Essential for Access projects (“big” items)
To be reinforced (e.g. 3D scans, viewers, etc.)
Civil Engineering needs Large works require ~2-3 years. Contact GS-SE asap
plan.cern.ch Essential to identify the “small” WP
Collect needs about storage, material, cleaning, waste
Complex changes must be ECRed ~1 year before
Stores & al. Anticipate project needs. Contact Stores and reply to surveys
