Compliance requirements

The tender documents include the standard exclusion grounds from the ESPD: participation in a criminal organisation, corruption, fraud, terrorist offences and related offences, money laundering, child labour and human trafficking, and other mandatory exclusion grounds under the Public Procurement Act. If an exclusion ground exists, the bidder may be allowed to prove self-cleaning measures where the law or tender documents permit it. The machine-readable notice did not provide the full list in a concise form, so the official tender documents should be checked for the exact grounds and any recovery/self-cleaning rules.
