Workpackages for CNGS CERN Neutrinos to Gran Sasso

Workpackages for CNGS (CERN Neutrinos to Gran Sasso) + experience with the CNGS project by Konrad Elsener, CERN (project leader 2000 -2006) Apologies: CNGS was a “small” project – few % of the LHC The CNGS project CNGS – same additional remarks --Project management tools used – work packages/units Acknowledgement: Malika Meddahi, Natacha Lopez 1

The CNGS project Task: build and commission a muon-neutrino beam at CERN in direction of Gran Sasso (Italy) 2

CNGS budget and schedule total materials budget (incl. contract labor): 77. 6 MCHF total CERN staff: 105 person-years 5

Civil Engineering > 3 km of tunnels several caverns > 45’ 000 m 3 of excavation > 12’ 000 m 3 of concrete poured + a 1 km long steel tube (vacuum decay tube) (2. 45 m diameter, 18 mm wall thickness, embedded in concrete) 6

CNGS “materials” budget (incl. contract labor) project budget total: 77. 6 MCHF of which “income” special contributions cash: 54. 3 MCHF special contributions “in-kind”: 6. 8 MCHF --------------------------------Civil Engineering (a) underground works 28. 8 MCHF (b) steel vacuum tube (decay) 8. 4 MCHF (c) consultants* for (a)+(b) 3. 7 MCHF Infrastructure 11. 0 MCHF Equipment 23. 2 MCHF Contingency 2. 5 MCHF 9 * includes a contract for safety co-ordination

CNGS project completed - on time - a few MCHF below the estimated cost beam fully operational: 18 August 2006 10

CNGS – additional remarks project “ready for approval” in Dec. 1998 one year to finalise layout, produce CE drawings -> saved a lot of money project approval Dec. 1999: 71 MCHF completion May 2005 “re-baseline” in 2002 77. 6 MCHF first beam May 2006 (minor) schedule change in 2006: first beam 10 July 2006 “end of project” 18 August 2006 11

27 October 2006: water leak on the “reflector” (2 nd focusing lens after target) experiment at Gran Sasso not ready – beam again mid-Sept. 2007 12

CNGS – before project approval (1997 -1999) Technical Committee on CERN-INFN Neutrino Programme 19 meetings in 20 months (2 INFN managers, 4 INFN neutrino physicists, + 18 CERN staff – chair: director of accelerators) CERN Internal Working Group 37 meetings in 24 months 1998: Conceptual Technical Design Report 1999: Addendum to C. T. D. R. no formal “value-engineering” performed – but a lot of brainstorming on possible cost reduction for CNGS 13

Project Management Tools standard methods and tools: -> PBS (“what? ” - product) -> Project Equipment Coding Convention (<->SPS) -> WBS (deliverables -> incl. project management, installation, commissioning) -> OBS. . . did not produce a RRM (Resource-Responsibility Matrix). . . May 2003: -> EVM (Earned Value Management) CERN Tool: PPT (Project Progress Tracking) -> work-units (incl. CERN manpower) 14

CNGS total: 112 workpackages 16

EVM for CNGS -- following the WBS 1 st baseline frozen 9 May 2003 (313 work-units) 2 nd baseline frozen 18 June 2004 at the end: 450 work-units 56 wu – project management / co-ordination 6 wu – civil engineering incl. decay tube, doors, etc. 230 wu – engineering and supply 9 – cooling, ventilation, electrical services 158 wu – installation in different areas 62 - cooling, ventilation, electrical services (10 wu cancelled ‘on the way’) NB. LHC has 12452 wu, 142 cancelled, 878 active, 218 late, 62 planned, 40 draft 21

Engineering Data Management System - EDMS (existing tool, cf. LHC) • allows data storage with many options. . . • in CNGS used for all files, including minutes, slides from presentations, internal notes, etc. (E -> electronic) • Engineering Change Request procedures • Non-Conformity procedures • CNGS-EDMS is now being used and updated by the teams operating the facility 27

CNGS-EDMS: Who are the users? Single storage/source of data Make sure that people find the right information (e. g. latest, approved or relevant information). D. Widegren 28

Summary • CNGS: a “medium-size” project (100 MCHF), 2000 -2006 • WBS (and EDMS) used from the project start 27 main branches; varying granularity 2 -(4) levels; total 112 entries in WBS N. B. CNGS-EDMS still extremely useful today • EVM (PPT) introduced at the end of 3 rd year would have been much easier at project start approx. 400 workunits N. B. PPT-CNGS still sometimes useful today 33
