A very rough cost estimate of the pre-isolator:  two 110 tons masses,  20 air-springs,  leveling system  position controls,  ~ 500 kCHf. But large uncertainties on civil engineering costs This does not includes R&D and prototypes.

Post-collision line vacuum for one side, thus (30% less for 2 nd one) 3.2 MCHF E.Gschwendtner, R.Veness

Main beam dumps No estimate has been made yet. But work starting in EN/STI group But an old ILC estimate (R.Appleby, Bangalore, 2006) raises some questions

Not yet studied:  BDS&MDI magnets, rectifiers and their various services  BDS collimators, optional muon sweepers  MDI vacuum  Support structures for QD0  Push-pull platforms + infrastructure  ….. Independent estimates to come from other groups:  Civil engineering and services (form CE working group)  Detectors (from PH-LCD)  ….

Some questions and remarks:  One is very happy that we have made good progress in the cost estimates, even though we are not yet at the end.  For the moment spares, CERN manpower, operational and R&D costs must not be included. However, tooling for installation must be.  Steiner Stapnes will want to discuss with some of us how to make sure that all is correctly counted, but not twice, in particular also concerning the detectors  The CES working group should do the costing for the cavern and services, but we shall montor that everything is included.  Elimination cost must be calculated in cases where it is important (dumps!), but will most likely not be quoted at the CDR stage  We must make progress with the estimates for the BDS  Philippe Lebrun and the management will see how the cost estimates for the beam dumps can be speeded up  The number of magnets for the post collision lines slide is not consistent with the final conclusion. Should they be made super conducting to reduce power consumption?

Next steps:  Regular follow-up of progress in Cost and Schedule Working Group meetings  Internal Review of the overall CLIC Cost Estimates on 9 th of December  External Cost Review Committee on 5 and 6 April 2011

Internal Review of CLIC CDR Value Estimate Guidelines for contents of presentations Presentations are made by PBS domain/subdomain coordinators, i.e. they follow the PBS description of the project Only material costs will be addressed for the time being Each presentation will be 20 min + 10 min questions Each presentation should contain – Brief description of the PBS domain/subdomain – PBS level(s) at which the elementary costs were input – Value estimate methodology: analytical/scaling Scaling variables and laws Possible application of learning curves (learning coefficients) Consistency with general schedule – Justification of elementary/unit costs, references, benchmarking Publications Earlier projects (CERN or elsewhere) Industrial cost studies When applicable, consistency check with ILC RDR – Summary tables of material value at 3 TeV and 500 GeV Installation through industrial contracts is part of material cost – Uncertainties: technical, commercial – Potential for further cost reduction/mitigation To be discussed
