Regulation 146. Clarification, specification, etc

Those tenders may be clarified, specified and optimised at the request of the contracting authority. However, such clarification, specification, optimisation or additional information may not involve changes to the essential aspects of the tender or of the public procurement, including the needs and requirements set out in the contract notice or in the descriptive document, where variations to those aspects, needs and requirements are likely to distort competition or have a discriminatory effect.
