Question details
Related to the References - (ToR page 21) - "Only references that are relevant and can be verified will be taken into consideration."
Is the EIB requiring proof for verification to be included in the tender? If so, would that be timesheets in the case of staffing projects? client certificates, or other?

It is up to the Tenderer to prove the validity of the references in whatever manner that is compatible with the request and available to the Tenderer.
