Article 168. Tender procedures with qualification systems.

1. Pursuant to article 141, paragraph 4, letter a), contracting authorities or granting bodies may establish and manage a qualification system for economic operators. Economic operators may request to be qualified at any time. 2. With their own documents, published on their institutional sites and, in any case, transmitted to interested economic operators who request them, the contracting authorities or granting bodies establish objective rules and criteria for the functioning of the qualification system, which can be divided into various qualification stages, any periodic updating of the same and its duration. They regulate the requirements relating to economic and financial capacity and the technical and professional skills necessary for registration in the system; the requirements may also be those provided for by articles 100 and 103 and in this case articles 91 and 105 apply. When the criteria for registration involve the possession of technical specifications, articles 79, 80 and 105 apply. 3. The contracting authorities or granting bodies provide in the documents referred to in paragraph 2 that economic operators for whom there are causes for exclusion pursuant to the combined provisions of articles 94, 95, 96, 97, 98 and 169 cannot be registered, and in any case they allow the acquisition of the capacity requirements required for registration in accordance with the methods set out in article 104. The rules and criteria can always be updated by communicating this to the registered economic operators. 4. The qualified operators are registered in a list, which can be divided into categories based on the type of procurement for which the qualification is valid. 5. The contracting authority or the granting body that establishes and manages the qualification system establishes the documents, certificates and substitute declarations that must accompany the application for registration, and cannot request certificates or documents that reproduce valid documents already in his availability. The documents, certificates and substitute declarations, if drawn up in a language other than Italian, are accompanied by a translation into Italian certified as compliant with the original text by the Italian diplomatic or consular authorities of the country in which they were drawn up, or by a official translator. 6. The specific contracts for the works, supplies and services covered by the qualification system are awarded with restricted procedures or negotiated procedures in which operators registered in the qualification system can participate or submit offers.
