  3. 1 • Page 3 • The Project does not contain Preconstruction • Costs (as Regards CFS Activities) : • Not Obvious which costs excluded • from Estimates GDE Meeting, Beijing, 4-7 February 2007

  4. CFS Preconstruction Costs • Civil Engineering – Basis of Costing Exercise (4) • Not Included in Cost Estimates : • All R&D (before T0) : Survey and Alignment for CFS only) • Geotechnical Investigations (before T0) : 0.3% of • Civil Engineering Costs • Purchase of Land (Surface, and Underground if needed) • Cost of Local Formalities (Impact Study, …) • Consultants, Architects, Experts fees before T0 : all design and Specifications up to Tender Stage, 3.5% of Civil Engineering Cost GDE Meeting, Beijing, 4-7 February 2007

  5. RDR/Reviews Bid to Host Specs Preparation of Bids to Host Site Selection Process EDR (All CFS) Selection of Main Consultants Site Investigations CE + other CFS Works Machine Supply, Install, Assembly TENTATIVE OVERALL TIME SCHEDULE T0 = 2012 2007 2018 -5 -4 -3 -1 +1 +2 +3 +4 +5 +6 +7 -2 DRAFT Site Independent Eng.

  6. 2 • Page 4 • Costs Risk Analysis for CFS Activities GDE Meeting, Beijing, 4-7 February 2007

  7. 3 • Page 5 • Optimization of Overall Heat Dissipation • Confirmation / Clarification on Air Conditioning • System Cost GDE Meeting, Beijing, 4-7 February 2007

  8. 4 • Page 6/1 • No Attempts Reported to Investigate • ILC Costs assuming a Shallow Site GDE Meeting, Beijing, 4-7 February 2007

  9. European Sites “For Reference” • DESY Site • Shallow Site (-10 m to -20 m) in Sedimentary Sand 70% and Marl (30%) in Water Table • Tunnel Excavation by Hydro or Earth Pressure Balanced TBMs, other Works from Surface • Design and Costing Carried Out to the Same Level of Detail as for the CERN Site, with the Same Consultant • Same Layouts adapted to Specificities of Site • Cost by Compare to CERN Site : • Total CFS : +13 % • Civil Engineering : + 20% • (1) Official Confirmation “for Reference” Not Received GDE Meeting, Beijing, 4-7 February 2007

  10. European Sites “For Reference” • DUBNA Site • Shallow Site (- 20 m average) in drift Clay under Superficial Layer of Alluvial Deposits • Tunnel Excavation by Shield TBMs, other Works from Surface • Cost Estimates Based on Valencia Layouts (Last Information Received by End November Possibly Not Taken into Account) • Cost by compare to CERN Site : • Total CFS : +9% • Civil Engineering : -13% (Underground -29%) • Electrical Engineering : +43% • Process Cooling Water : +58% • (2) According to Last Information Provided by G. Shirkov 11-12-06 GDE Meeting, Beijing, 4-7 February 2007

  13. GDE Meeting, Beijing, 4-7 February 2007

  14. 5 • Page 6/2 • Lists of Buildings : Two Lists needed, One • for Needed Buildings on a Stand Alone Site, • One for Sites close to Existing HEP • Laboratories GDE Meeting, Beijing, 4-7 February 2007

  16. 6 • Page 6/3 • Shaft Diameter depending on Details of the • Cavity Module Cryostat Design • Overall Savings for reducing the • 14 m Shafts to 9 m Diameter. GDE Meeting, Beijing, 4-7 February 2007

  17. SHAFTS Diameter Reduction from 14 m to 9 m • (Shafts 2, 3, 4, 5, 10, 11) • EUROPE : • ∆ Cost : 100’523 – 49’818 = 50’705 USD/m • Average depth : 100 m • Savings : 50’705 x 6 x 100 = 30.4 MUSD • + 10% uncertainties on moraines = - 33.5 MUSD • AMERICAS : • ∆ Cost : 134’768 – 78’280 = 56’488 USD/m • Average depth : 135 m • Savings : 56’488 x 6 x 135 = -45.8 MUSD • ASIA : Not Applicable (Slopped Access Galleries) • Additional Costs on Reinforcement of Modules Structures to • be assessed by RF GDE Meeting, Beijing, 4-7 February 2007

  18. 7 • Page 7 • Give the Cost and Benefits for an Insulated • Water Return Pipe. • Give Consequences for Rising the Delta • For Water Temperature • (of more than the present 10°C) GDE Meeting, Beijing, 4-7 February 2007

  19. 8 • Page 7 • The Committee suggests reassessing the Specified Emergency Power Value since it appears quite Low. GDE Meeting, Beijing, 4-7 February 2007

  20. Emergency Power Value (1) • What should be taken for emergency power needs further consideration • and clear decision at EDR stage • At present stage, we guestimated that following items should be considered: • - Emergency ventilation • - Emergency ligthing • - Emergency drainage pumps • - Alarms and signalling systems • - Access control systems • - lifts GDE Meeting, Beijing, 4-7 February 2007

  21. Emergency Power Value (2) • Steady state consumption is 1.4 MW • Emergency supply system as designed and costed allows for 5 to 10 MW • Inrush current for users requires a factor of 2 to 3 • We suggest to state 3.8 MW in EMER column of power table • hence an overall total of 229.7 MW • However main cost driver is distance rather than power GDE Meeting, Beijing, 4-7 February 2007

  22. 9 • Page 8 • Combination of Service Access Shaft and Neighboring Detector Installation ? • Reasons for the Necessity of an Access • Shaft over the Service Cavern for BDS Area. GDE Meeting, Beijing, 4-7 February 2007

  23. Reasons for Necessity of an Access Shaft to the Service Cavern of the BDS Area System • Easy and Direct Access to all Equipment/Components • in Service cavern • Safety Access Required to such a Large cavern • Possibility to Access the Service cavern at all Times • (Shielding not Required) • Specific Crane and Lift in the Service Shaft : no need • for time sharing with one of the Detectors (nearest one) • Direct Access to the BDS Service Tunnel : easier transport • of BDS equipment from the surface • Easier Access to Survey Galleries for Alignment of Machine/Detectors Components • Access to Detectors hall in case of Failure of Lowering Equipment • in the 16 m Diameter Shafts over the Detector Hall • CE Cost : Europe ~ 5.5 MUSD • Americas ~ 10.6 MUSD • Asia ~ 13.7 MUSD GDE Meeting, Beijing, 4-7 February 2007
