1. Contracting authorities and contracting entities shall treat economic operators equally and without discrimination and shall act in a transparent and proportionate manner. The design of the concession award procedure, including the estimate of the value, shall not be made with the intention of excluding it from the scope of this Directive or of unduly favouring or disadvantaging certain economic operators or certain works, supplies or services. 2. Contracting authorities and contracting entities shall aim at ensuring the transparency of the award procedure and of the performance of the contract, while complying with Article 28.
