En outre, la Commission considère que la modification des conditions d'attribution du marché public en question postérieurement à la publication de l'avis d'appel d'offres, notamment en ce qui concerne la classification des travaux à réaliser, représente une infraction aux principes du traité CE, notamment les principes de transparence et de non-discrimination, dans la mesure où cette modification tardive n'a pas permis à tous les opérateurs, intéressés et qualifiés pour les travaux après modification du projet, de participer à la procédure d'adjudication.
First of all, the Commission considers that the contract being awarded is to be qualified as a public works contract and not as a public works concession. As a consequence, the award of a public contract through a procedure, such as that of "project financing", aimed at the award of a works concession constitutes a violation of Dire
ctive 93/37/EEC. In addition, the Commission considers that the
modification of the conditions for the award of the public contract in question after the publication of the tender notice, in particular with
...[+++] respect to the classification of the works to be realised, amounts to a breach of EC Treaty principles, and in particular the principles of transparency and non-discrimination, in so far as it has not allowed all operators, interested in and qualified for the works resulting from the modified project, to take part in the tendering procedure.
