HL – LHC WBS & more Project Coordination Office supporting the HL Project Isabel Bejar Alonso, Joao Carlos Batista Lopes, Claudia Parente
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
Modifying at least 1.2 Km of an existing machine 3000 fb-1 in 10 years Limited pile up : 140 5 1035levelled
Modifying at least 1.2 Km of an existing machine Collimation Cryogenics IR Magnets
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
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.
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.
Starting point And not only
To be done for every existing system installed Identify the changes included in the HL scope and prepare a list of deliverables
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
WBS as the starting point for the …ing DELIVERABLES TASKS & ACTIVITIES SCHEDULE EVM BUDGET RESOURCES MILESTONES RISK REGISTER RISK …
Supporting the Technical processes performance and interface requirements … but not only
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”
“Design constrains” hierarchy Safety Quality Technical Called sometimes “constrains”; Safety, Quality and Technical requirements have to be added to the performance and interface requirements identified during the conceptual phase
Codes & Standards Advantages 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. • 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
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
Standards evolution since the LHC Two examples: • Cold masses (dipoles) • Vacuum vessels
Do not reuse your old specs …. LHC PRESENTLY IT-2799 / CM dipoles IT-2544 / Vacuum vessels
The complete map contains the groups that were used in old specs + what we think you could need Standards architecture ICS A non-exhaustive overview of some fields and their corresponding groups and sub-groups* Manufacturing engineering Metallurgy Electrical engineering FIELDS GROUPS Iron and steel products Insulating materials Welding, brazing and soldering Iron and steel castings Magnetic materials Welded joints SUB-GROUPS Iron and steel forgings Superconductivity and conducting materials Welding processes Steels for pressure purposes Brazing and soldering Testing of metals Mechanical testing of metals Non-destructive testing of metals * based on the International Classification of Standards (ICS)
Standards – Present scenario Examples Manufacturing engineering Welding processes Fusion welding Welding joints Metallurgy Iron and steel products Iron and steel castings Identification with the WPE the interesting subgroups Mechanical testing of metals Non-destructive testing of metals
Welding and allied processes - Fusion welding Specified in its superseded /replaced version Specified in its valid version Approval testing of welders
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
Safety requirements But how to identify the applicable ones
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
