art_83__para_6
6. Contracting authorities and contracting entities may on an exceptional basis decide not to apply paragraph 2 of this Article where, after preliminary market consultation in line with Article 40 of Directive 2014/24/EU and Article 58 of Directive 2014/25/EU, it was found that: the required construction product can only be supplied by a specific economic operator, and no reasonable alternative or substitute exists; no suitable tenders or no suitable requests to participate have been submitted in response to a previous public procurement procedure; or the application of paragraph 1 or the incorporation of the required construction product in construction works would oblige that contracting authority or contracting entity to incur disproportionate costs, or would result in incompatibility or technical difficulties. Contracting authorities and contracting entities may presume that estimated contract value differences above 10 %, based on objective and transparent data, are disproportionate. When contracting authorities and contracting entities use the derogation in this paragraph, the procurement procedure cannot be considered to be environmentally sustainable in relation to the construction products to which the exceptions have been applied. Every three years, Member States shall report to the Commission about the use of this paragraph, in accordance with Article 83 of Directive 2014/24/EU. This paragraph shall be without prejudice to the possibility of excluding abnormally low tenders under Article 69 of Directive 2014/24/EU and Article 84 of Directive 2014/25/EU.
