Costing GuidelinesCosting Guidelines
The RDR is not a complete Technical/Engineering Design a design made to the level required to support a
reliable cost estimate
Good common sense has to be applied to level of engineering/costing Main Linac, CF&S
cost drivers: pay attention to details Injectors, DRs, BDS
not cost drivers: can make looser cost estimates
Nick Walker – SA meeting KEK 19.01.06
Example: US studyExample: US studynote: US accountingfull-cost model
CF&S included for each system

Cost Drivers: SCRF tech.Cost Drivers: SCRF tech.
bottom-up cost detailed cost estimate based on existing information (TDR, USLCOS) new input from industrial studies (US?) (XFEL TDR cost update)
May have largest uncertainty International agreed upon model for
costing SCRF tech. needed
Nick Walker – SA meeting KEK 19.01.06
Cost Drivers: CF&SCost Drivers: CF&S Civil engineering requirements must be well specified
tunnel diameters, lengths # of shafts, access etc PPS zones shielding requirements for hi rad areas etc. surface building requirements (space!)
scaling from existing machines or similar engineering projects useful
site dependencies may exist Must have a clear picture of what you want to go into a
tunnel, shaft, hall or building

Cost Drivers: CF&SCost Drivers: CF&S
Cooling & AC power requirements input needed from AS on
magnets, power supplies, electronic racks, klystrons/modulators etc.
some can be scaled from existing infrastructures
Special case: cryogenics look to LHC…
Nick Walker – SA meeting KEK 19.01.06
Non Cost DriversNon Cost Drivers
Careful: taken together still ¼-1/3 of total cost magnets: rough estimates of IV parameters, cooling
requirements needed based on field specs from AS No need to perform detailed magnet design
~30% best guess ~2% TPC
(warm) vacuum systems: rough design; scale from existing machines
controls (inc. software), instrumentation… rough counts, scale from existing experience

WBS is needed to define the level of cost detail required
First-pass at WBS (level of detail) can be made from experience
Will need to iterate as costs begin to arrive Our first job! Define the WBS
