Is it an important question ?
My answer is YES
The answer to the question « are the functional specifications better or more suitable than build to print order » is not binary : Yes or No
I like to rephrase the question

Case Study 2 ( Antoine) : Magnets Conventional magnets and superconducting magnets
In the case of conventional magnets , CERN will usually give just a principle design , interface definition with implementation constraints and requested performances
WHY ? Because many companies have now the competences to design and build conventional magnets and CERN should not do what European industry can do.
In the case of superconducting magnets , CERN will usually give a fully detailed design and drawings which are very close to fabrication drawings. And CERN keeps the functional responsibility
WHY ? Because no company has the necessary full skil to design frontier edge magnets and some of the procurements have to be launched well in advance to meet schedule

Where to put the cursor ?
Conventional magnets : we are very close to fully functional specifications but not 100% because a preliminary design is always useful to fix all the interface details

Where to put the cursor ?

Superconducting magnets : we are on the build to print model but not 100% because the fabrication drawings , in the workshop, are always reviewed by the Company.

8. Case Study 3 ( Antoine) : Collimators
The procurement strategy for the new HL-LHC collimators at present involves four major contracts :
the supply of raw material for the jaws’ back-stiffener,
the supply of low-impedance absorbing blocks,
the supply of cradles and supports,
a final contract for the remaining mechanical manufacturing and assembly
Additional components will be purchased using standard price inquiries or invitations to tender
We can hardly imagine to procure these sophisticated and so critical equipment on the basis of functional specifications

10. Case Study 4 ( Antoine) : HVAC
CERN’s cooling and ventilation systems consist of 4 000 heating, ventilation and air-conditioning (HVAC) installations, cooling and fluid distribution facilities, compressed-air and demineralised water production plants, fire-fighting systems, discharge pumping stations and waste-water pumping systems.
This equipment is critical for safety and for the operation of the accelerators and the experiments.
New large scale facilities , like ITER or ESS , are contracting “turn-key” and the scope includes operation and maintenance.
This method is difficult in a existing facility but evolution may be discussed

Comments and potential evolutions : Antoine Why CERN is more often on the “Buid to print” side ?
Because equipment are usually specific and highly sophisticated
Because the main duty of CERN being to serve Physics by operating the accelerator chain, CERN teams need to master completely those equipment
Because CERN has internally very powerful and competent engineering teams able to produce the suitable detailed designs
Also present CERN good practices are consistent with the procurement rules
I am personnally in favor of suitable evolutions , mainly in the procurement of conventional hardware , especially when available « from the shelf » or easy to develop in European industry
