Process

  1. Bidder submits a question via procurement platform
  2. Authority reviews and anonymizes the question
  3. Authority formulates a clear answer
  4. Answer is published to all bidders

Binding Effect

Clarifications are binding. Corrections modify tender documents and must be observed. In case of contradictions, the more recent version prevails.
