2. Why we are having this presentation? 2

3. 3 Three main messages WBS why it is so important and why will be used as starting point for most project processes Standards – what tools we will have to ensure that we use the “right” ones while preparing the design files Safety – how to integrate it from the beginning

4. 4 Modifying at least 1.2 Km of an existing machine 3000 fb -1 in 10 years Limited pile up : 140  5 10 35 levelled 3000 fb -1 in 10 years Limited pile up : 140  5 10 35 levelled

5. 5 Modifying at least 1.2 Km of an existing machine Cryogenics Collimation IR Magnets

6. 6 And modifying means … New systems New equipment for existing systems Modifications to the present systems to adapt to the new equipment/system “Consolidation” (even if handled outside HL) Dismantling and elimination of equipment replaced

7. 7 WBS some concepts Definition “The Work breakdown structure is a deliverable-oriented hierarchical decomposition of the work to be executed by the project team to accomplish the project objectives and create the required deliverables. The WBS organizes and defines the total scope of the project” (PMBOK) Why - To ensure a clear definition and communication of project scope - To have a baseline for planning, costing, scheduling, …ing.

8. 8 WBS some concepts - Deliverable Definition “Any unique and verifiable product, result, or capability to perform a service that must be produced to complete a process, phase or project. ” (PMBOK) Important A deliverable is not a task or an activity. You will need those to obtain the deliverable. What at CERN we call Work packages is not what the PMBOK calls Work Packages as they are not the lowest level in the WBS.

9. 9 Starting point And not only

10. 10 To be done for every existing system installed Identify the changes included in the HL scope and prepare a list of deliverables

11. 11 To be done for every deliverable Every deliverable shall be linked to an LHC system or declared as a new LHC system /subsystem (ex. Halo control) Every deliverable is assigned to a HL WP. New HL WPs will be created if required

12. 12 As a collaborative process

13. 13 As a structured process

14. 14 Supported by guides and templates

15. 15 WBS as the starting point for the …ing DELIVERABLES TASKS & ACTIVITIES SCHEDULE RESOURCES BUDGET MILESTONES EVMEVM EVMEVM RISK RISK REGISTER …

16. 16 Supporting the Technical processes performance and interface requirements … but not only

17. 17 From Concept to Design Once finalized the Conceptual phase we will enter the Implementation phase where the functional specifications will become design files for components that will be fabricated. To the existing performance, and interface requirements we will have to add “design constraints”

18. “Design constrains” hierarchy Rules & Regulations Codes and standards Specific technologies and methods SafetyQualityTechnical Called sometimes “constrains”; Safety, Quality and Technical requirements have to be added to the performance and interface requirements identified during the conceptual phase

19. Codes & Standards Advantages Increased confidence on the Quality of equipment Increase of equipment’s reliability and availability Minimization of risks and costs Ensures Compliance with CERN Safety rules/EU regulations Presumption of conformity with the Essential Safety Requirements of EU directives (whenever applicable) by using Harmonized Standards Disadvantages Codes and standards are not (yet, or completely) cost free or Global market oriented 55% and 70% of all European standards adopted by CEN and CENELEC are technically equivalent or identical to ISO and IEC standards, respectively Unified approach still to be extended to other standards development organizations namely in the US.

20. Codes & Standards Reliability and Availability Working in a Radioactive environment Minimization of risks and costs Components Designed and built around the globe But how to identify the applicable ones

21. Standards evolution since the LHC Two examples: Cold masses (dipoles) Vacuum vessels

22. Do not reuse your old specs …. IT-2544 / Vacuum vessels IT-2799 / CM dipoles LHC PRESENTLY

23. Standards architecture ICS Manufacturing engineering Welding processes Welded joints * based on the International Classification of Standards (ICS) Brazing and soldering A non-exhaustive overview of some fields and their corresponding groups and sub-groups* Welding, brazing and soldering Metallurgy Iron and steel products Iron and steel castings Iron and steel forgings Steels for pressure purposes Testing of metals Mechanical testing of metals Non-destructive testing of metals Electrical engineering Superconductivity and conducting materials Insulating materials Magnetic materials FIELDS GROUPS SUB-GROUPS The complete map contains the groups that were used in old specs + what we think you could need

24. Standards – Present scenario Manufacturing engineering Welding processes Welding joints Iron and steel products Mechanical testing of metals Non-destructive testing of metals Iron and steel castings Metallurgy Fusion welding Examples Identification with the WPE the interesting subgroups

25. Welding and allied processes - Fusion welding Specified in its superseded /replaced version Specified in its valid version Approval testing of welders

26. Iron and steel castings

27. Mechanical testing of metals

28. 28 Codes & Standards maps A guide to identify if there is an standard that guides you to fulfill your quality/technical/ safety requirements A basis for benchmarking and best practices ICS makes easier to find the equivalence in other countries

29. Safety requirements Rules & Regulations But how to identify the applicable ones

30. 30 Guided process

31. 31 With roles and responsibilities identified

32. 32 Documentation

33. 33 What, when, where, why, …

34. 34 Conclusions & Next steps WBS as an enabler that ensures clear definition and communication of the project scope Structured approach with well defined processes Guidelines and training to ensure a common approach Support to identify the design requirements with maps identifying standards by applicable categories and international equivalences Support to identify safety requirements by hazards with forms Lists of applicable documents for each phase with templates and clear approval and distribution processes
