1. The calculation of the estimated value of a concession shall be based on the total amount payable, net of VAT, as estimated by the contracting authority or the contracting entity, including any form of option and any extension of the duration of the concession.
2. The estimated value of a concession shall be calculated as the value of an entirety of works or services, even if purchased through different contracts, where the contracts are part of one single project. Indications for the existence of one single project consist in overall prior planning and conception by the contracting authority or contracting entity, the fact that the different elements purchased fulfil a single economic and technical function or that they are otherwise logically interlinked.
Where the contracting authority or the contracting entity provides for prizes or payments to candidates or tenderers it shall take them into account when calculating the estimated value of the concession.
3. The choice of the method used to calculate the estimated value of a concession shall not be made with the intention of excluding it from the scope of this Directive. A works project or an entirety of services shall not be subdivided with the effect of preventing it from falling within the scope of this Directive, unless justified by objective reasons.
4. This estimate shall be valid at the moment at which the concession notice is sent, or, in cases where such notice is not foreseen, at the moment at which the contracting authority or the contracting entity commences the concession award procedure, in particular by defining the essential characteristics of the intended concession.
5. With regard to public works concessions and works concessions, calculation of the estimated value shall take account of both the cost of the works and the total estimated value of the supplies and services that are made available to the contractor by the contracting authorities or entities provided that they are necessary for executing the works.
6. Where a proposed work or purchase of services may result in concessions being awarded at the same time in the form of separate lots, account shall be taken of the total estimated value of all such lots.
7. Where the aggregate value of the lots is equal to or exceeds the threshold laid down in Article 5, this Directive shall apply to the awarding of each lot.
8. Contracting authorities or contracting entities may award concessions for individual lots without applying the provisions on the award provided for under this Directive, provided that the estimated value net of VAT of the lot concerned is less than EUR 1 million. However, the aggregate value of the lots thus awarded without applying this Directive shall not exceed 20% of the aggregate value of all the lots into which the proposed work or the proposed purchase of services has been divided.
9. The value of services concessions shall be the estimated total value of services to be provided by the concessionaire during the whole duration of the concession, calculated in accordance with an objective methodology which shall be specified in the concession notice or in the concession documents.
The basis for calculating the estimated concession value shall, where appropriate, be the following:
(a) for insurance services: the premium payable and other forms of remuneration;
(b) for banking and other financial services: fees, commissions, interest and other forms of remuneration;
(c) for design services: fees, commission payable and other forms of remuneration;
10. The value of concessions shall include both the estimated revenue to be received from third parties and the amounts to be paid by the contracting authority or the contracting entity.
