When awarding public contracts, contracting authorities shall apply the national procedures adjusted to be in conformity with this Directive, provided that, without prejudice to Article 32, a call for competition has been published in accordance with this Directive.

Member States shall provide that contracting authorities may apply open or restricted procedures as regulated in this Directive.

Member States shall provide that contracting authorities may apply innovation partnerships as regulated in this Directive.

The call for competition shall be made by means of a contract notice pursuant to Article 49.

Where the contract is awarded by restricted procedure or competitive procedure with negotiation, Member States may provide, notwithstanding the first subparagraph of this paragraph, that sub-central contracting authorities or specific categories thereof may make the call for competition by means of a prior information notice pursuant to Article 48(2).

Where the call for competition is made by means of a prior information notice pursuant to Article 48(2), economic operators having expressed their interest following the publication of the prior information notice shall subsequently be invited to confirm their interest in writing by means of an invitation to confirm interest in conformity with Article 54.

In the specific cases and circumstances referred to expressly in Article 32, Member States may provide that contracting authorities may apply a negotiated procedure without prior publication of a call for competition. Member States shall not allow the application of that procedure in any other cases than those referred to in Article 32.

In open procedures, any interested economic operator may submit a tender in response to a call for competition.

The minimum time limit for the receipt of tenders shall be 35 days from the date on which the contract notice was sent.

The tender shall be accompanied by the information for qualitative selection that is requested by the contracting authority.

Where a state of urgency duly substantiated by the contracting authority renders impracticable the time limit laid down in the second subparagraph of paragraph 1, it may fix a time limit which shall be not less than 15 days from the date on which the contract notice was sent.

The contracting authority may reduce by five days the time limit for receipt of tenders set out in the second subparagraph of paragraph 1 of this Article where it accepts that tenders may be submitted by electronic means in accordance with the first subparagraph of Article 22(1), and Article 22(5) and (6).

In restricted procedures, any economic operator may submit a request to participate in response to a call for competition containing the information set out in Annex V parts B or C as the case may be by providing the information for qualitative selection that is requested by the contracting authority.

The minimum time limit for receipt of requests to participate shall be 30 days from the date on which the contract notice or, where a prior information notice is used as a means of calling for competition, the invitation to confirm interest was sent.

Only those economic operators invited to do so by the contracting authority following its assessment of the information provided may submit a tender. Contracting authorities may limit the number of suitable candidates to be invited to participate in the procedure in accordance with Article 65.

The minimum time limit for the receipt of tenders shall be 30 days from the date on which the invitation to tender was sent.

Member States may provide that all or specific categories of sub-central contracting authorities may set the time limit for the receipt of tenders by mutual agreement between the contracting authority and the selected candidates, provided that all selected candidates have the same time to prepare and submit their tenders. In the absence of agreement on the time limit for the receipt of tenders, the time limit shall be at least 10 days from the date on which the invitation to tender was sent.

The time limit for receipt of tenders provided for in paragraph 2 of this Article may be reduced by five days where the contracting authority accepts that tenders may be submitted by electronic means in conformity with Article 22(1), (5) and (6).

In competitive procedures with negotiation, any economic operator may submit a request to participate in response to a call for competition containing the information set out in Annex V parts B and C by providing the information for qualitative selection that is requested by the contracting authority.

In the procurement documents, contracting authorities shall identify the subject-matter of the procurement by providing a description of their needs and the characteristics required of the supplies, works or services to be procured and specify the contract award criteria. They shall also indicate which elements of the description define the minimum requirements to be met by all tenders.

The information provided shall be sufficiently precise to enable economic operators to identify the nature and scope of the procurement and decide whether to request to participate in the procedure.

The minimum time limit for receipt of requests to participate shall be 30 days from the date on which the contract notice or, where a prior information notice is used as a means of calling for competition, the invitation to confirm interest was sent. The minimum time limit for the receipt of initial tenders shall be 30 days from the date on which the invitation was sent. Article 28(3) to (6) shall apply.

Only those economic operators invited by the contracting authority following its assessment of the information provided may submit an initial tender which shall be the basis for the subsequent negotiations. Contracting authorities may limit the number of suitable candidates to be invited to participate in the procedure in accordance with Article 65.

Unless otherwise provided for in paragraph 4, contracting authorities shall negotiate with tenderers the initial and all subsequent tenders submitted by them, except for the final tenders within the meaning of paragraph 7, to improve the content thereof.

The minimum requirements and the award criteria shall not be subject to negotiations.

Contracting authorities may award contracts on the basis of the initial tenders without negotiation where they have indicated, in the contract notice or in the invitation to confirm interest, that they reserve the possibility of doing so.

During the negotiations, contracting authorities shall ensure the equal treatment of all tenderers. To that end, they shall not provide information in a discriminatory manner which may give some tenderers an advantage over others. They shall inform all tenderers, whose tenders have not been eliminated pursuant to paragraph 6, in writing of any changes to the technical specifications or other procurement documents, other than those setting out the minimum requirements. Following these changes, contracting authorities shall provide sufficient time for tenderers to modify and re-submit amended tenders, as appropriate.

In accordance with Article 21, contracting authorities shall not reveal to the other participants confidential information communicated by a candidate or a tenderer participating in the negotiations without its agreement. Such agreement shall not take the form of a general waiver but shall be given with reference to the intended communication of specific information.

Competitive procedures with negotiation may take place in successive stages in order to reduce the number of tenders to be negotiated by applying the award criteria specified in the contract notice, in the invitation to confirm interest or in another procurement document. In the contract notice, the invitation to confirm interest or in another procurement document, the contracting authority shall indicate whether it will use that option.

Where the contracting authority intends to conclude the negotiations, it shall inform the remaining tenderers and set a common deadline to submit any new or revised tenders. It shall verify that the final tenders are in conformity with the minimum requirements and comply with Article 56(1), assess the final tenders on the basis of the award criteria and award the contract in accordance with Articles 66 to 69.

In competitive dialogues, any economic operator may submit a request to participate in response to a contract notice by providing the information for qualitative selection that is requested by the contracting authority.

The minimum time limit for receipt of requests to participate shall be 30 days from the date on which the contract notice was sent.

Only those economic operators invited by the contracting authority following the assessment of the information provided may participate in the dialogue. Contracting authorities may limit the number of suitable candidates to be invited to participate in the procedure in accordance with Article 65. The contract shall be awarded on the sole basis of the award criterion of the best price-quality ratio in accordance with Article 67(2).

Contracting authorities shall set out their needs and requirements in the contract notice and they shall define these needs and requirements in that notice and/or in a descriptive document. At the same time and in the same documents, they shall also set out and define the chosen award criteria and set out an indicative timeframe.

Contracting authorities shall open, with the participants selected in accordance with the relevant provisions of Articles 56 to 66, a dialogue the aim of which shall be to identify and define the means best suited to satisfying their needs. They may discuss all aspects of the procurement with the chosen participants during this dialogue.

During the dialogue, contracting authorities shall ensure equality of treatment among all participants. To that end, they shall not provide information in a discriminatory manner which may give some participants an advantage over others.

In accordance with Article 21, contracting authorities shall not reveal to the other participants solutions proposed or other confidential information communicated by a candidate or tenderer participating in the dialogue without its agreement. Such agreement shall not take the form of a general waiver but shall be given with reference to the intended communication of specific information.

Competitive dialogues may take place in successive stages in order to reduce the number of solutions to be discussed during the dialogue stage by applying the award criteria laid down in the contract notice or in the descriptive document. In the contract notice or the descriptive document, the contracting authority shall indicate whether it will use that option.

The contracting authority shall continue the dialogue until it can identify the solution or solutions which are capable of meeting its needs.

Having declared that the dialogue is concluded and having so informed the remaining participants, contracting authorities shall ask each of them to submit their final tenders on the basis of the solution or solutions presented and specified during the dialogue. Those tenders shall contain all the elements required and necessary for the performance of the project.

Those tenders may be clarified, specified and optimised at the request of the contracting authority. However, such clarification, specification, optimisation or additional information may not involve changes to the essential aspects of the tender or of the public procurement, including the needs and requirements set out in the contract notice or in the descriptive document, where variations to those aspects, needs and requirements are likely to distort competition or have a discriminatory effect.

Contracting authorities shall assess the tenders received on the basis of the award criteria laid down in the contract notice or in the descriptive document.

At the request of the contracting authority, negotiations with the tenderer identified as having submitted the tender presenting the best price-quality ratio in accordance with Article 67 may be carried out to confirm financial commitments or other terms contained in the tender by finalising the terms of the contract provided this does not have the effect of materially modifying essential aspects of the tender or of the public procurement, including the needs and requirements set out in the contract notice or in the descriptive document and does not risk distorting competition or causing discrimination.

Contracting authorities may specify prizes or payments to the participants in the dialogue.

In innovation partnerships, any economic operator may submit a request to participate in response to a contract notice by providing the information for qualitative selection that is requested by the contracting authority.

In the procurement documents, the contracting authority shall identify the need for an innovative product, service or works that cannot be met by purchasing products, services or works already available on the market. It shall indicate which elements of this description define the minimum requirements to be met by all tenders. The information provided shall be sufficiently precise to enable economic operators to identify the nature and scope of the required solution and decide whether to request to participate in the procedure.

The contracting authority may decide to set up the innovation partnership with one partner or with several partners conducting separate research and development activities.

The minimum time limit for receipt of requests to participate shall be 30 days from the date on which the contract notice is sent. Only those economic operators invited by the contracting authority following the assessment of the information provided may participate in the procedure. Contracting authorities may limit the number of suitable candidates to be invited to participate in the procedure in accordance with Article 65. The contracts shall be awarded on the sole basis of the award criterion of the best price-quality ratio in accordance with Article 67.

The innovation partnership shall aim at the development of an innovative product, service or works and the subsequent purchase of the resulting supplies, services or works, provided that they correspond to the performance levels and maximum costs agreed between the contracting authorities and the participants.

The innovation partnership shall be structured in successive phases following the sequence of steps in the research and innovation process, which may include the manufacturing of the products, the provision of the services or the completion of the works. The innovation partnership shall set intermediate targets to be attained by the partners and provide for payment of the remuneration in appropriate instalments.

Based on those targets, the contracting authority may decide after each phase to terminate the innovation partnership or, in the case of an innovation partnership with several partners, to reduce the number of partners by terminating individual contracts, provided that the contracting authority has indicated in the procurement documents those possibilities and the conditions for their use.

Unless otherwise provided for in this Article, contracting authorities shall negotiate with tenderers the initial and all subsequent tenders submitted by them, except for the final tender, to improve the content thereof.

The minimum requirements and the award criteria shall not be subject to negotiations.

During the negotiations, contracting authorities shall ensure the equal treatment of all tenderers. To that end, they shall not provide information in a discriminatory manner which may give some tenderers an advantage over others. They shall inform all tenderers whose tenders have not been eliminated, pursuant to paragraph 5, in writing of any changes to the technical specifications or other procurement documents other than those setting out the minimum requirements. Following those changes, contracting authorities shall provide sufficient time for tenderers to modify and re-submit amended tenders, as appropriate.

In accordance with Article 21, contracting authorities shall not reveal to the other participants confidential information communicated by a candidate or tenderer participating in the negotiations without its agreement. Such agreement shall not take the form of a general waiver but shall be given with reference to the intended communication of specific information.

Negotiations during innovation partnership procedures may take place in successive stages in order to reduce the number of tenders to be negotiated by applying the award criteria specified in the contract notice, in the invitation to confirm interest or in the procurement documents. In the contract notice, the invitation to confirm interest or in the procurement documents, the contracting authority shall indicate whether it will use that option.

In selecting candidates, contracting authorities shall in particular apply criteria concerning the candidates’ capacity in the field of research and development and of developing and implementing innovative solutions.

Only those economic operators invited by the contracting authority following its assessment of the requested information may submit research and innovation projects aimed at meeting the needs identified by the contracting authority that cannot be met by existing solutions.

In the procurement documents, the contracting authority shall define the arrangements applicable to intellectual property rights. In the case of an innovation partnership with several partners, the contracting authority shall not, in accordance with Article 21, reveal to the other partners solutions proposed or other confidential information communicated by a partner in the framework of the partnership without that partner’s agreement. Such agreement shall not take the form of a general waiver but shall be given with reference to the intended communication of specific information.

The contracting authority shall ensure that the structure of the partnership and, in particular, the duration and value of the different phases reflect the degree of innovation of the proposed solution and the sequence of the research and innovation activities required for the development of an innovative solution not yet available on the market. The estimated value of supplies, services or works shall not be disproportionate in relation to the investment required for their development.

In the specific cases and circumstances laid down in paragraphs 2 to 5, Member States may provide that contracting authorities may award public contracts by a negotiated procedure without prior publication.

The negotiated procedure without prior publication may be used for public service contracts, where the contract concerned follows a design contest organised in accordance with this Directive and is to be awarded, under the rules provided for in the design contest, to the winner or one of the winners of the design contest; in the latter case, all winners must be invited to participate in the negotiations.

The negotiated procedure without prior publication may be used for new works or services consisting in the repetition of similar works or services entrusted to the economic operator to which the same contracting authorities awarded an original contract, provided that such works or services are in conformity with a basic project for which the original contract was awarded pursuant to a procedure in accordance with Article 26(1). The basic project shall indicate the extent of possible additional works or services and the conditions under which they will be awarded.

As soon as the first project is put up for tender, the possible use of this procedure shall be disclosed and the total estimated cost of subsequent works or services shall be taken into consideration by the contracting authorities when they apply Article 4.

This procedure may be used only during the three years following the conclusion of the original contract.
