Compliance requirements
The bidder and relevant persons authorised to represent, manage or control it must declare whether any exclusion grounds apply. These include convictions for participation in a criminal organisation, corruption, fraud, terrorist offences, money laundering or terrorist financing, child labour or human trafficking; tax or social security contribution arrears; breaches of environmental, social or labour obligations; insolvency, bankruptcy or suspended business activity; serious professional misconduct, anti-competitive agreements, conflicts of interest, involvement in preparing the procurement, serious failures under previous contracts, and false or misleading statements or failure to provide required information or documents. National grounds also cover enabling the unlawful employment of a foreign national, international sanctions, tax offences and any applicable local tax debt or restriction on participation. A tax debt below EUR 100 or a debt whose payment has been rescheduled is addressed under the stated national tax rules. Where legally permitted, the bidder may provide evidence of measures taken to restore its reliability. The bidder must also provide the names and personal identification codes of authorised persons not identifiable from the commercial register, or confirm that there are no such persons.

Contract details must be listed; client confirmations may be requested if the information cannot be verified in public records. The bidder must operate a quality management system certified to ISO 9001 or an equivalent standard and provide the certificate or equivalent independent evidence when requested.
