DIRECTIVE 2014/24/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 26 February 2014

on public procurement and repealing Directive 2004/18/EC

(Text with EEA relevance)







THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty on the Functioning of the European Union, and in particular Article 53(1), Article 62 and Article 114 thereof, Having regard to the proposal from the European Commission, After transmission of the draft legislative act to the national parliaments, Having regard to the opinion of the European Economic and Social Committee ( 1 ), Having regard to the opinion of the Committee of the Regions ( 2 ), Acting in accordance with the ordinary legislative procedure ( 3 ), Whereas: (1) The award of public contracts by or on behalf of Member States’ authorities has to comply with the principles of the Treaty on the Functioning of the European Union (TFEU), and in particular the free movement of goods, freedom of establishment and the freedom to provide services, as well as the principles deriving therefrom, such as equal treatment, non-discrimination, mutual recognition, proportionality and transparency. However, for public contracts above a certain value, provisions should be drawn up coordinating national procurement procedures so as to ensure that those principles are given practical effect and public procurement is opened up to competition. (2) Public procurement plays a key role in the Europe 2020 strategy, set out in the Commission Communication of 3 March 2010 entitled ‘Europe 2020, a strategy for smart, sustainable and inclusive growth’ (‘Europe 2020 strategy for smart, sustainable and inclusive growth’), as one of the market-based instruments to be used to achieve smart, sustainable and inclusive growth while ensuring the most efficient use of public funds. For that purpose, the public procurement rules adopted pursuant to Directive 2004/17/EC of the European Parliament and of the Council ( 4 ) and Directive 2004/18/EC of the European Parliament and of the Council ( 5 ) should be revised and modernised in order to increase the efficiency of public spending, facilitating in particular the participation of small and medium-sized enterprises (SMEs) in public procurement, and to enable procurers to make better use of public procurement in support of common societal goals. There is also a need to clarify basic notions and concepts to ensure legal certainty and to incorporate certain aspects of related well-established case-law of the Court of Justice of the European Union. (3) When implementing this Directive, the United Nations Convention on the Rights of Persons with Disabilities ( 6 ) should be taken into account, in particular in connection with the choice of means of communications, technical specifications, award criteria and contract performance conditions. (4) The increasingly diverse forms of public action have made it necessary to define more clearly the notion of procurement itself; that clarification should not however broaden the scope of this Directive compared to that of Directive 2004/18/EC. The Union rules on public procurement are not intended to cover all forms of disbursement of public funds, but only those aimed at the acquisition of works, supplies or services for consideration by means of a public contract. It should be clarified that such acquisitions of works, supplies or services should be subject to this Directive whether they are implemented through purchase, leasing or other contractual forms. The notion of acquisition should be understood broadly in the sense of obtaining the benefits of the works, supplies or services in question, not necessarily requiring a transfer of ownership to the contracting authorities. Furthermore, the mere financing, in particular through grants, of an activity, which is frequently linked to the obligation to reimburse the amounts received where they are not used for the purposes intended, does not usually fall within the scope of the public procurement rules. Similarly, situations where all operators fulfilling certain conditions are entitled to perform a given task, without any selectivity, such as customer choice and service voucher systems, should not be understood as being procurement but simple authorisation schemes (for instance licences for medicines or medical services). (5) It should be recalled that nothing in this Directive obliges Member States to contract out or externalise the provision of services that they wish to provide themselves or to organise by means other than public contracts within the meaning of this Directive. The provision of services based on laws, regulations or employment contracts should not be covered. In some Member States, this might for example be the case for certain administrative and government services such as executive and legislative services or the provision of certain services to the community, such as foreign affairs services or justice services or compulsory social security services. (6) It is also appropriate to recall that this Directive should not affect the social security legislation of the Member States. Nor should it deal with the liberalisation of services of general economic interest, reserved to public or private entities, or with the privatisation of public entities providing services. It should equally be recalled that Member States are free to organise the provision of compulsory social services or of other services such as postal services either as services of general economic interest or as non-economic services of general interest or as a mixture thereof. It is appropriate to clarify that non-economic services of general interest should not fall within the scope of this Directive. (7) It should finally be recalled that this Directive is without prejudice to the freedom of national, regional and local authorities to define, in conformity with Union law, services of general economic interest, their scope and the characteristics of the service to be provided, including any conditions regarding the quality of the service, in order to pursue their public policy objectives. This Directive should also be without prejudice to the power of national, regional and local authorities to provide, commission and finance services of general economic interest in accordance with Article 14 TFEU and Protocol No 26 on Services of General Interest annexed to the TFEU and to the Treaty on European Union (TEU). In addition, this Directive does not deal with the funding of services of general economic interest or with systems of aid granted by Member States, in particular in the social field, in accordance with Union rules on competition. (8) A contract should be deemed to be a public works contract only if its subject-matter specifically covers the execution of activities listed in Annex II, even if the contract covers the provision of other services necessary for the execution of such activities. Public service contracts, in particular in the sphere of property management services, may, in certain circumstances, include works. However, in so far as such works are incidental to the principal subject-matter of the contract, and are a possible consequence thereof or a complement thereto, the fact that such works are included in the contract does not justify the qualification of the public service contract as a public works contract. However, in view of the diversity of public works contracts, contracting authorities should be able to make provision for contracts for the design and execution of work to be awarded either separately or jointly. This Directive is not intended to prescribe either joint or separate contract awards. (9) The realisation of a work corresponding to the requirements specified by a contracting authority requires that the authority in question must have taken measures to define the type of the work or, at the very least, have had a decisive influence on its design. Whether the contractor realises all or part of the work by his own means or ensures their realisation by other means should not change the classification of the contract as a works contract, as long as the contractor assumes a direct or indirect obligation that is legally enforceable to ensure that the works will be realised. (10) The notion of ‘contracting authorities’ and in particular that of ‘bodies governed by public law’ have been examined repeatedly in the case-law of the Court of Justice of the European Union. To clarify that the scope of this Directive ratione personae should remain unaltered, it is appropriate to maintain the definitions on which the Court based itself and to incorporate a certain number of clarifications given by that case-law as a key to the understanding of the definitions themselves, without the intention of altering the understanding of the concepts as elaborated by the case-law. For that purpose, it should be clarified that a body which operates in normal market conditions, aims to make a profit, and bears the losses resulting from the exercise of its activity should not be considered as being a ‘body governed by public law’ since the needs in the general interest, that it has been set up to meet or been given the task of meeting, can be deemed to have an industrial or commercial character. Similarly, the condition relating to the origin of the funding of the body considered, has also been examined in the case-law, which has clarified inter alia that being financed for ‘the most part’ means for more than half, and that such financing may include payments from users which are imposed, calculated and collected in accordance with rules of public law. (11) In the case of mixed contracts, the applicable rules should be determined with respect to the main subject of the contract where the different parts which constitute the contract are objectively not separable. It should therefore be clarified how contracting authorities should determine whether the different parts are separable or not. Such clarification should be based on the relevant case-law of the Court of Justice of the European Union. The determination should be carried out on a case-by-case basis, in which the expressed or presumed intentions of the contracting authority to regard the various aspects making up a mixed contract as indivisible should not be sufficient, but should be supported by objective evidence capable of justifying them and of establishing the need to conclude a single contract. Such a justified need to conclude a single contract could for instance be present in the case of the construction of one single building, a part of which is to be used directly by the contracting authority concerned and another part to be operated on a concessions basis, for instance to provide parking facilities to the public. It should be clarified that the need to conclude a single contract may be due to reasons both of a technical nature and of an economic nature. (12) In the case of mixed contracts which can be separated, contracting authorities are always free to award separate contracts for the separate parts of the mixed contract, in which case the provisions applicable to each separate part should be determined exclusively with respect to the characteristics of that specific contract. On the other hand, where contracting authorities choose to include other elements in the procurement, whatever their value and whatever the legal regime the added elements would otherwise have been subject to, the main principle should be that, where a contract should be awarded pursuant to the provisions of this Directive, if awarded on its own, then this Directive should continue to apply to the entire mixed contract. (13) However, special provision should be made for mixed contracts involving defence or security aspects or parts not falling within the scope of the TFEU. In such cases, non-application of this Directive should be possible provided that the award of a single contract is justified for objective reasons and that the decision to award a single contract is not taken for the purpose of excluding contracts from the application of this Directive or of Directive 2009/81/EC of the European Parliament and of the Council ( 7 ). It should be clarified that contracting authorities should not be prevented from choosing to apply this Directive to certain mixed contracts instead of applying Directive 2009/81/EC. (14) It should be clarified that the notion of ‘economic operators’ should be interpreted in a broad manner so as to include any persons and/or entities which offer the execution of works, the supply of products or the provision of services on the market, irrespective of the legal form under which they have chosen to operate. Thus, firms, branches, subsidiaries, partnerships, cooperative societies, limited companies, universities, public or private, and other forms of entities than natural persons should all fall within the notion of economic operator, whether or not they are ‘legal persons’ in all circumstances. (15) It should be clarified that groups of economic operators, including where they have come together in the form of a temporary association, may participate in award procedures without it being necessary for them to take on a specific legal form. To the extent this is necessary, for instance where joint and several liability is required, a specific form may be required when such groups are awarded the contract. It should also be clarified that contracting authorities should be able to set out explicitly how groups of economic operators are to meet the requirements concerning economic and financial standing as set out in this Directive, or the criteria relating to technical and professional ability, which are required of economic operators participating on their own. The performance of contracts by groups of economic operators may necessitate setting conditions which are not imposed on individual participants. Such conditions, which should be justified by objective reasons and be proportionate, could for instance include requiring the appointment of a joint representation or a lead partner for the purposes of the procurement procedure or requiring information on their constitution. (16) Contracting authorities should make use of all possible means at their disposal under national law in order to prevent distortions in public procurement procedures stemming from conflicts of interest. This could include procedures to identify, prevent and remedy conflicts of interests. (17) Council Decision 94/800/EC ( 8 ) approved in particular the World Trade Organisation Agreement on Government Procurement (the ‘GPA’). The aim of the GPA is to establish a multilateral framework of balanced rights and obligations relating to public contracts with a view to achieving the liberalisation and expansion of world trade. For contracts covered by Annexes 1, 2, 4 and 5 and the General Notes to the European Union’s Appendix I to the GPA, as well as by other relevant international agreements by which the Union is bound, contracting authorities should fulfil the obligations under those agreements by applying this Directive to economic operators of third countries that are signatories to the agreements. (18) The GPA applies to contracts above certain thresholds, set in the GPA and expressed as special drawing rights. The thresholds laid down by this Directive should be aligned to ensure that they correspond to the euro equivalents of the thresholds of the GPA. Provision should also be made for periodic reviews of the thresholds expressed in euros so as to adjust them, by means of a purely mathematical operation, to possible variations in the value of the euro in relation to those special drawing rights. Apart from those periodic mathematical adjustments, an increase in the thresholds set in the GPA should be explored during the next round of negotiations thereof. (19) It should be clarified that, for the estimation of the value of a contract, all revenues have to be taken into account, whether received from the contracting authority or from third parties. It should also be clarified that, for the purpose of estimating the thresholds, the notion of similar supplies should be understood as products which are intended for identical or similar uses, such as supplies of a range of foods or of various items of office furniture. Typically, an economic operator active in the field concerned would be likely to carry such supplies as part of his normal product range. (20) For the purposes of estimating the value of a given procurement, it should be clarified that it should be allowed to base the estimation of the value on a subdivision of the procurement only where justified by objective reasons. For instance, it could be justified to estimate contract values at the level of a separate operational unit of the contracting authority, such as for instance schools or kindergartens, provided that the unit in question is independently responsible for its procurement. This can be assumed where the separate operational unit independently runs the procurement procedures and makes the buying decisions, has a separate budget line at its disposal for the procurements concerned, concludes the contract independently and finances it from a budget which it has at its disposal. A subdivision is not justified where the contracting authority merely organises a procurement in a decentralised way. (21) Public contracts that are awarded by contracting authorities operating in the water, energy, transport and postal services sectors and that fall within the scope of those activities are covered by Directive 2014/25/EU of the European Parliament and of the Council ( 9 ). However, contracts awarded by contracting authorities in the context of their operation of maritime, coastal or river transport services fall within the scope of this Directive. (22) Being addressed to Member States, this Directive does not apply to procurement carried out by international organisations on their own behalf and for their own account. There is, however, a need to clarify to what extent this Directive should be applied to procurement governed by specific international rules. (23) The awarding of public contracts for certain audiovisual and radio media services by media providers should allow aspects of cultural or social significance to be taken into account, which renders the application of procurement rules inappropriate. For those reasons, an exception should therefore be made for public service contracts, awarded by the media service providers themselves, for the purchase, development, production or co-production of off-the-shelf programmes and other preparatory services, such as those relating to scripts or artistic performances necessary for the production of the programme. It should also be clarified that that exclusion should apply equally to broadcast media services and on-demand services (non-linear services). However, that exclusion should not apply to the supply of technical equipment necessary for the production, co-production and broadcasting of such programmes. (24) It should be recalled that arbitration and conciliation services and other similar forms of alternative dispute resolution are usually provided by bodies or individuals which are agreed on, or selected, in a manner which cannot be governed by procurement rules. It should be clarified that this Directive does not apply to service contracts for the provision of such services, whatever their denomination under national law. (25) A certain number of legal services are rendered by service providers that are designated by a court or tribunal of a Member State, involve representation of clients in judicial proceedings by lawyers, must be provided by notaries or are connected with the exercise of official authority. Such legal services are usually provided by bodies or individuals designated or selected in a manner which cannot be governed by procurement rules, such as for instance the designation of State Attorneys in certain Member States. Those legal services should therefore be excluded from the scope of this Directive. (26) It is appropriate to specify that the notion of financial instruments as referred to in this Directive is given the same meaning as in other internal market legislation and, in view of the recent creation of the European Financial Stability Facility and the European Stability Mechanism, it should be stipulated that operations conducted with that Facility and that Mechanism should be excluded from the scope of this Directive. It should finally be clarified that loans, whether or not they are in connection with the issuing of securities or other financial instruments or other operations therewith, should be excluded from the scope of this Directive. (27) It should be recalled that Article 5(1) of Regulation (EC) No 1370/2007 of the European Parliament and of the Council ( 10 ) explicitly provides that Directives 2004/17/EC and 2004/18/EC apply, respectively, to service contracts and public service contracts for public passenger transport services by bus or tramway, whereas Regulation (EC) No 1370/2007 applies to service concessions for public passenger transport by bus or tramway. It should furthermore be recalled that that Regulation continues to apply to public service contracts as well as to service concessions for public passenger transport by rail or metro. To clarify the relationship between this Directive and Regulation (EC) No 1370/2007, it should be provided explicitly that this Directive should not be applicable to public service contracts for the provision of public passenger transport services by rail or metro, the award of which should continue to be subject to that Regulation. In so far as Regulation (EC) No 1370/2007 leaves it to national law to depart from the rules laid down in that Regulation, Member States should be able to continue to provide in their national law that public service contracts for public passenger transport services by rail or metro are to be awarded by a contract award procedure following their general public procurement rules. (28) This Directive should not apply to certain emergency services where they are performed by non-profit organisations or associations, since the particular nature of those organisations would be difficult to preserve if the service providers had to be chosen in accordance with the procedures set out in this Directive. However, the exclusion should not be extended beyond that strictly necessary. It should therefore be set out explicitly that patient transport ambulance services should not be excluded. In that context it is furthermore necessary to clarify that CPV Group 601 ‘Land Transport Services’ does not cover ambulance services, to be found in CPV class 8514. It should therefore be clarified that services, which are covered by CPV code 85143000-3, consisting exclusively of patient transport ambulance services should be subject to the special regime set out for social and other specific services (the ‘light regime’). Consequently, mixed contracts for the provision of ambulance services in general would also be subject to the light regime if the value of the patient transport ambulance services were greater than the value of other ambulance services. (29) It is appropriate to recall that this Directive applies only to contracting authorities of Member States. Consequently, political parties in general, not being contracting authorities, are not subject to its provisions. However, political parties in some Member States might fall within the notion of bodies governed by public law. However, certain services (such as propaganda film and video-tape production) are so inextricably connected to the political views of the service provider when provided in the context of an election campaign, that the service providers are normally selected in a manner which cannot be governed by procurement rules. Finally, it should be recalled that the statute and funding of European political parties and European political foundations are subject to rules other than those laid down in this Directive. (30) In certain cases, a contracting authority or an association of contracting authorities may be the sole source for a particular service, in respect of the provision of which it enjoys an exclusive right pursuant to laws, regulations or published administrative provisions which are compatible with the TFEU. It should be clarified that this Directive need not apply to the award of public service contracts to that contracting authority or association. (31) There is considerable legal uncertainty as to how far contracts concluded between entities in the public sector should be covered by public procurement rules. The relevant case-law of the Court of Justice of the European Union is interpreted differently between Member States and even between contracting authorities. It is therefore necessary to clarify in which cases contracts concluded within the public sector are not subject to the application of public procurement rules. Such clarification should be guided by the principles set out in the relevant case-law of the Court of Justice of the European Union. The sole fact that both parties to an agreement are themselves public authorities does not as such rule out the application of procurement rules. However, the application of public procurement rules should not interfere with the freedom of public authorities to perform the public service tasks conferred on them by using their own resources, which includes the possibility of cooperation with other public authorities. It should be ensured that any exempted public-public cooperation does not result in a distortion of competition in relation to private economic operators in so far as it places a private provider of services in a position of advantage vis-à-vis its competitors. (32) Public contracts awarded to controlled legal persons should not be subject to the application of the procedures provided for by this Directive if the contracting authority exercises a control over the legal person concerned which is similar to that which it exercises over its own departments, provided that the controlled legal person carries out more than 80 % of its activities in the performance of tasks entrusted to it by the controlling contracting authority or by other legal persons controlled by that contracting authority, regardless of the beneficiary of the contract performance. The exemption should not extend to situations where there is direct participation by a private economic operator in the capital of the controlled legal person since, in such circumstances, the award of a public contract without a competitive procedure would provide the private economic operator with a capital participation in the controlled legal person an undue advantage over its competitors. However, in view of the particular characteristics of public bodies with compulsory membership, such as organisations responsible for the management or exercise of certain public services, this should not apply in cases where the participation of specific private economic operators in the capital of the controlled legal person is made compulsory by a national legislative provision in conformity with the Treaties, provided that such participation is non-controlling and non-blocking and does not confer a decisive influence on the decisions of the controlled legal person. It should further be clarified that the decisive element is only the direct private participation in the controlled legal person. Therefore, where there is private capital participation in the controlling contracting authority or in the controlling contracting authorities, this does not preclude the award of public contracts to the controlled legal person, without applying the procedures provided for by this Directive as such participations do not adversely affect competition between private economic operators. It should also be clarified that contracting authorities such as bodies governed by public law, that may have private capital participation, should be in a position to avail themselves of the exemption for horizontal cooperation. Consequently, where all other conditions in relation to horizontal cooperation are met, the horizontal cooperation exemption should extend to such contracting authorities where the contract is concluded exclusively between contracting authorities. (33) Contracting authorities should be able to choose to provide jointly their public services by way of cooperation without being obliged to use any particular legal form. Such cooperation might cover all types of activities related to the performance of services and responsibilities assigned to or assumed by the participating authorities, such as mandatory or voluntary tasks of local or regional authorities or services conferred upon specific bodies by public law. The services provided by the various participating authorities need not necessarily be identical; they might also be complementary. Contracts for the joint provision of public services should not be subject to the application of the rules set out in this Directive provided that they are concluded exclusively between contracting authorities, that the implementation of that cooperation is governed solely by considerations relating to the public interest and that no private service provider is placed in a position of advantage vis-à-vis its competitors. In order to fulfil those conditions, the cooperation should be based on a cooperative concept. Such cooperation does not require all participating authorities to assume the performance of main contractual obligations, as long as there are commitments to contribute towards the cooperative performance of the public service in question. In addition, the implementation of the cooperation, including any financial transfers between the participating contracting authorities, should be governed solely by considerations relating to the public interest. (34) Certain cases exist where a legal entity acts, under the relevant provisions of national law, as an instrument or technical service to determined contracting authorities, is obliged to carry out orders given to it by those contracting authorities and has no influence on the remuneration for its performance. In view of its non-contractual nature, such a purely administrative relationship should not fall within the scope of public procurement procedures. (35) The co-financing of research and development (R&D) programmes by industry sources should be encouraged. It should consequently be clarified that this Directive applies only where there is no such co-financing and where the outcome of the R&D activities go to the contracting authority concerned. This should not exclude the possibility that the service provider, having carried out those activities, could publish an account thereof as long as the contracting authority retains the exclusive right to use the outcome of the R&D in the conduct of its own affairs. However fictitious sharing of the results of the R&D or purely symbolic participation in the remuneration of the service provider should not prevent the application of this Directive. (36) Employment and occupation contribute to integration in society and are key elements in guaranteeing equal opportunities for all. In this context, sheltered workshops can play a significant role. The same is true for other social businesses whose main aim is to support the social and professional integration or reintegration of disabled and disadvantaged persons, such as the unemployed, members of disadvantaged minorities or otherwise socially marginalised groups. However, such workshops or businesses might not be able to obtain contracts under normal conditions of competition. Consequently, it is appropriate to provide that Member States should be able to reserve the right to participate in award procedures for public contracts or for certain lots thereof to such workshops or businesses or reserve performance of contracts to the context of sheltered employment programmes. (37) With a view to an appropriate integration of environmental, social and labour requirements into public procurement procedures it is of particular importance that Member States and contracting authorities take relevant measures to ensure compliance with obligations in the fields of environmental, social and labour law that apply at the place where the works are executed or the services provided and result from laws, regulations, decrees and decisions, at both national and Union level, as well as from collective agreements, provided that such rules, and their application, comply with Union law. Equally, obligations stemming from international agreements ratified by all Member States and listed in Annex X should apply during contract performance. However, this should in no way prevent the application of terms and conditions of employment which are more favourable to workers. The relevant measures should be applied in conformity with the basic principles of Union law, in particular with a view to ensuring equal treatment. Such relevant measures should be applied in accordance with Directive 96/71/EC of the European Parliament and of the Council ( 11 ) and in a way that ensures equal treatment and does not discriminate directly or indirectly against economic operators and workers from other Member States. (38) Services should be considered to be provided at the place at which the characteristic performances are executed. When services are provided at a distance, for example services provided by call centres, those services should be considered to be provided at the place where the services are executed, irrespective of the places and Member States to which the services are directed. (39) The relevant obligations could be mirrored in contract clauses. It should also be possible to include clauses ensuring compliance with collective agreements in compliance with Union law in public contracts. Non-compliance with the relevant obligations could be considered to be grave misconduct on the part of the economic operator concerned, liable to exclusion of that economic operator from the procedure for the award of a public contract. (40) Control of the observance of the environmental, social and labour law provisions should be performed at the relevant stages of the procurement procedure, when applying the general principles governing the choice of participants and the award of contracts, when applying the exclusion criteria and when applying the provisions concerning abnormally low tenders. The necessary verification for that purpose should be carried out in accordance with the relevant provisions of this Directive, in particular those governing means of proof and self-declarations. (41) Nothing in this Directive should prevent the imposition or enforcement of measures necessary to protect public policy, public morality, public security, health, human and animal life, the preservation of plant life or other environmental measures, in particular with a view to sustainable development, provided that those measures are in conformity with the TFEU. (42) There is a great need for contracting authorities to have additional flexibility to choose a procurement procedure, which provides for negotiations. A greater use of those procedures is also likely to increase cross-border trade, as the evaluation has shown that contracts awarded by negotiated procedure with prior publication have a particularly high success rate of cross-border tenders. Member States should be able to provide for the use of the competitive procedure with negotiation or the competitive dialogue, in various situations where open or restricted procedures without negotiations are not likely to lead to satisfactory procurement outcomes. It should be recalled that use of the competitive dialogue has significantly increased in terms of contract values over the past years. It has shown itself to be of use in cases where contracting authorities are unable to define the means of satisfying their needs or of assessing what the market can offer in terms of technical, financial or legal solutions. This situation may arise in particular with innovative projects, the implementation of major integrated transport infrastructure projects, large computer networks or projects involving complex and structured financing. Where relevant, contracting authorities should be encouraged to appoint a project leader to ensure good cooperation between the economic operators and the contracting authority during the award procedure. (43) For works contracts, such situations include works that are not standard buildings or where works includes design or innovative solutions. For services or supplies that require adaptation or design efforts, the use of a competitive procedure with negotiation or competitive dialogue is likely to be of value. Such adaptation or design efforts are particularly necessary in the case of complex purchases such as sophisticated products, intellectual services, for example some consultancy services, architectural services or engineering services, or major information and communications technology (ICT) projects. In those cases, negotiations may be necessary to guarantee that the supply or service in question corresponds to the needs of the contracting authority. In respect of off-the-shelf services or supplies that can be provided by many different operators on the market, the competitive procedure with negotiation and competitive dialogue should not be used. (44) The competitive procedure with negotiation should also be available in cases where an open or restricted procedure resulted only in irregular or unacceptable tenders. In such cases, contracting authorities should be allowed to conduct negotiations with the aim of obtaining regular and acceptable tenders. (45) The competitive procedure with negotiation should be accompanied by adequate safeguards ensuring observance of the principles of equal treatment and transparency. In particular, contracting authorities should indicate beforehand the minimum requirements which characterise the nature of the procurement and which should not be changed in the negotiations. Award criteria and their weighting should remain stable throughout the entire procedure and should not be subject to negotiations, in order to guarantee equal treatment of all economic operators. Negotiations should aim at improving the tenders so as to allow contracting authorities to buy works, supplies and services perfectly adapted to their specific needs. Negotiations may concern all characteristics of the purchased works, supplies and services including, for instance, quality, quantities, commercial clauses as well as social, environmental and innovative aspects, in so far as they do not constitute minimum requirements. It should be clarified that the minimum requirements to be set by the contracting authority are those conditions and characteristics (particularly physical, functional and legal) that any tender should meet or possess in order to allow the contracting authority to award the contract in accordance with the chosen award criteria. In order to ensure transparency and traceability of the process, all stages should be duly documented. Furthermore, all tenders throughout the procedure should be submitted in writing. (46) Contracting authorities should be allowed to shorten certain deadlines applicable to open and restricted procedures and to competitive procedures with negotiation where the deadlines in question would be impracticable because of a state of urgency which should be duly substantiated by the contracting authorities. It should be clarified that this need not be an extreme urgency brought about by events unforeseeable for and not attributable to the contracting authority. (47) Research and innovation, including eco-innovation and social innovation, are among the main drivers of future growth and have been put at the centre of the Europe 2020 strategy for smart, sustainable and inclusive growth. Public authorities should make the best strategic use of public procurement to spur innovation. Buying innovative products, works and services plays a key role in improving the efficiency and quality of public services while addressing major societal challenges. It contributes to achieving best value for public money as well as wider economic, environmental and societal benefits in terms of generating new ideas, translating them into innovative products and services and thus promoting sustainable economic growth. It should be recalled that a series of procurement models have been outlined in the Commission Communication of 14 December 2007 entitled ‘Pre-commercial Procurement: Driving innovation to ensure sustainable high quality public services in Europe’, which deals with the procurement of those R&D services not falling within the scope of this Directive. Those models would continue to be available, but this Directive should also contribute to facilitating public procurement of innovation and help Member States in achieving the Innovation Union targets. (48) Because of the importance of innovation, contracting authorities should be encouraged to allow variants as often as possible. The attention of those authorities should consequently be drawn to the need to define the minimum requirements to be met by variants before indicating that variants may be submitted. (49) Where a need for the development of an innovative product or service or innovative works and the subsequent purchase of the resulting supplies, services or works cannot be met by solutions already available on the market, contracting authorities should have access to a specific procurement procedure in respect of contracts falling within the scope of this Directive. This specific procedure should allow contracting authorities to establish a long-term innovation partnership for the development and subsequent purchase of a new, innovative product, service or works provided that such innovative product or service or innovative works can be delivered to agreed performance levels and costs, without the need for a separate procurement procedure for the purchase. The innovation partnership should be based on the procedural rules that apply to the competitive procedure with negotiation and contracts should be awarded on the sole basis of the best price-quality ratio, which is most suitable for comparing tenders for innovative solutions. Whether in respect of very large projects or smaller innovative projects, the innovation partnership should be structured in such a way that it can provide the necessary ‘market-pull’, incentivising the development of an innovative solution without foreclosing the market. Contracting authorities should therefore not use innovation partnerships in such a way as to prevent, restrict or distort competition. In certain cases, setting up innovation partnerships with several partners could contribute to avoiding such effects. (50) In view of the detrimental effects on competition, negotiated procedures without prior publication of a contract notice should be used only in very exceptional circumstances. This exception should be limited to cases where publication is either not possible, for reasons of extreme urgency brought about by events unforeseeable for and not attributable to the contracting authority, or where it is clear from the outset that publication would not trigger more competition or better procurement outcomes, not least because there is objectively only one economic operator that can perform the contract. This is the case for works of art, where the identity of the artist intrinsically determines the unique character and value of the art object itself. Exclusivity can also arise from other reasons, but only situations of objective exclusivity can justify the use of the negotiated procedure without publication, where the situation of exclusivity has not been created by the contracting authority itself with a view to the future procurement procedure. Contracting authorities relying on this exception should provide reasons why there are no reasonable alternatives or substitutes such as using alternative distribution channels including outside the Member State of the contracting authority or considering functionally comparable works, supplies and services. Where the situation of exclusivity is due to technical reasons, they should be rigorously defined and justified on a case-by-case basis. They could include, for instance, near technical impossibility for another economic operator to achieve the required performance or the necessity to use specific know-how, tools or means which only one economic operator has at its disposal. Technical reasons may also derive from specific interoperability requirements which must be fulfilled in order to ensure the functioning of the works, supplies or services to be procured. Finally, a procurement procedure is not useful where supplies are purchased directly on a commodity market, including trading platforms for commodities such as agricultural products, raw materials and energy exchanges, where the regulated and supervised multilateral trading structure naturally guarantees market prices. (51) It should be clarified that the provisions concerning protection of confidential information do not in any way prevent public disclosure of non-confidential parts of concluded contracts, including any subsequent changes. (52) Electronic means of information and communication can greatly simplify the publication of contracts and increase the efficiency and transparency of procurement processes. They should become the standard means of communication and information exchange in procurement procedures, as they greatly enhance the possibilities of economic operators to participate in procurement procedures across the internal market. For that purpose, transmission of notices in electronic form, electronic availability of the procurement documents and – after a transition period of 30 months – fully electronic communication, meaning communication by electronic means at all stages of the procedure, including the transmission of requests for participation and, in particular, the transmission of the tenders (electronic submission) should be made mandatory. Member States and contracting authorities should remain free to go further if they so wish. It should also be clarified that mandatory use of electronic means of communications pursuant to this Directive should not, however, oblige contracting authorities to carry out electronic processing of tenders, nor should it mandate electronic evaluation or automatic processing. Furthermore, pursuant to this Directive, no elements of the public procurement process after the award of the contract should be covered by the obligation to use electronic means of communication, nor should internal communication within the contracting authority. (53) Contracting authorities should, except in certain specific situations, use electronic means of communication which are non-discriminatory, generally available and interoperable with the ICT products in general use and which do not restrict economic operators’ access to the procurement procedure. The use of such means of communication should also take accessibility for persons with disabilities into due account. It should be clarified that the obligation to use electronic means at all stages of the public procurement procedure would be appropriate neither where the use of electronic means would require specialised tools or file formats that are not generally available nor where the communications concerned could only be handled using specialised office equipment. Contracting authorities should therefore not be obliged to require the use of electronic means of communication in the submission process in certain cases, which should be listed exhaustively. This Directive stipulates that such cases should include situations which would require the use of specialised office equipment not generally available to the contracting authorities such as wide-format printers. In some procurement procedures the procurement documents might require the submission of a physical or scale model which cannot be submitted to the contracting authorities using electronic means. In such situations, the model should be transmitted to the contracting authorities by post or other suitable carrier. It should however be clarified that the use of other means of communication should be limited to those elements of the tender for which electronic means of communications are not required. It is appropriate to clarify that, where necessary for technical reasons, contracting authorities should be able to set a maximum limit to the size of the files that may be submitted. (54) There can be exceptional cases in which contracting authorities should be allowed not to use electronic means of communication where not using such means of communication is necessary in order to protect the particularly sensitive nature of information. It should be clarified that, where the use of electronic tools which are not generally available can offer the necessary level of protection, such electronic tools should be used. Such might for instance be the case where contracting authorities require the use of dedicated secure means of communication to which they offer access. (55) Differing technical formats or processes and messaging standards could potentially create obstacles to interoperability, not only within each Member State but also and especially between the Member States. For example, in order to participate in a procurement procedure in which use of electronic catalogues, which is a format for the presentation and organisation of information in a manner that is common to all the participating bidders and which lends itself to electronic treatment, is permitted or required, economic operators would, in the absence of standardisation, be required to customise their own catalogues to each procurement procedure, which would entail providing very similar information in different formats depending on the specifications of the contracting authority concerned. Standardising the catalogue formats would thus improve the level of interoperability, enhance efficiency and would also reduce the effort required of economic operators. (56) When considering whether there is a need to ensure or enhance interoperability between differing technical formats or process and messaging standards by rendering the use of specific standards mandatory, and if so which standards to impose, the Commission should take the utmost account of the opinions of the stakeholders concerned. It should also consider the extent to which a given standard has already been used in practice by economic operators and contracting authorities and how well it has worked. Before making the use of any particular technical standard mandatory, the Commission should also carefully consider the costs that this might entail, in particular in terms of adaptations to existing e-procurement solutions, including infrastructure, processes or software. Where the standards concerned are not developed by an international, European or national standardisation organisation, they should meet the requirements applicable to ICT standards as set out in Regulation (EU) 1025/2012 of the European Parliament and of the Council ( 12 ). (57) Before specifying the level of security required for the electronic means of communications to be used at the various stages of the award procedure, Member States and contracting authorities should evaluate the proportionality between on the one hand the requirements aimed at ensuring correct and reliable identification of the senders of the communication concerned as well as the integrity of its content, and on the other hand the risk of problems such as in situations where messages are sent by a different sender than that indicated. All other things being equal, this would mean that the level of security required of, for instance, an email requesting confirmation of the exact address at which an information meeting will be held would not need to be set at the same level as for the tender itself which constitutes a binding offer for the economic operator. Similarly, the evaluation of proportionality could result in lower levels of security being required in connection with the resubmission of electronic catalogues or the submission of tenders in the context of mini-competitions under a framework agreement or the access to procurement documents. (58) While essential elements of a procurement procedure such as the procurement documents, requests for participation, confirmation of interest and tenders should always be made in writing, oral communication with economic operators should otherwise continue to be possible, provided that its content is documented to a sufficient degree. This is necessary to ensure an adequate level of transparency that allows for a verification of whether the principle of equal treatment has been adhered to. In particular, it is essential that oral communications with tenderers which could have an impact on the content and assessment of the tenders be documented to a sufficient extent and by appropriate means, such as written or audio records or summaries of the main elements of the communication. (59) There is a strong trend emerging across Union public procurement markets towards the aggregation of demand by public purchasers, with a view to obtaining economies of scale, including lower prices and transaction costs, and to improving and professionalising procurement management. This can be achieved by concentrating purchases either by the number of contracting authorities involved or by volume and value over time. However, the aggregation and centralisation of purchases should be carefully monitored in order to avoid excessive concentration of purchasing power and collusion, and to preserve transparency and competition, as well as market access opportunities for SMEs. (60) The instrument of framework agreements has been widely used and is considered as an efficient procurement technique throughout Europe. It should therefore be maintained largely as it is. However, certain aspects need to be clarified, in particular that framework agreements should not be used by contracting authorities which are not identified in them. For that purpose, the contracting authorities that are parties to a specific framework agreement from the outset should be clearly indicated, either by name or by other means, such as a reference to a given category of contracting authorities within a clearly delimited geographical area, so that the contracting authorities concerned can be easily and unequivocally identified. Likewise, a framework agreement should not be open to entry of new economic operators once it has been concluded. This implies for instance that where a central purchasing body uses an overall register of the contracting authorities or categories thereof, such as the local authorities in a given geographical area, that are entitled to have recourse to framework agreements it concludes, that central purchasing body should do so in a way that makes it possible to verify not only the identity of the contracting authority concerned but also the date from which it acquires the right to have recourse to the framework agreement concluded by the central purchasing body as that date determines which specific framework agreements that contracting authority should be allowed to use. (61) The objective conditions for determining which of the economic operators party to the framework agreement should perform a given task, such as supplies or services intended for use by natural persons, may, in the context of framework agreements setting out all the terms, include the needs or the choice of the natural persons concerned. Contracting authorities should be given additional flexibility when procuring under framework agreements, which are concluded with more than one economic operator and which set out all the terms. In such cases, contracting authorities should be allowed to obtain specific works, supplies or services, that are covered by the framework agreement, either by requiring them from one of the economic operators, determined in accordance with objective criteria and on the terms already set out, or by awarding a specific contract for the works, supplies or services concerned following a mini-competition among the economic operators parties to the framework agreement. To ensure transparency and equal treatment, contracting authorities should indicate in the procurement documents for the framework agreement the objective criteria that will govern the choice between those two methods of performing the framework agreement. Such criteria could for instance relate to the quantity, value or characteristics of the works, supplies or services concerned, including the need for a higher degree of service or an increased security level, or to developments in price levels compared to a predetermined price index. Framework agreements should not be used improperly or in such a way as to prevent, restrict or distort competition. Contracting authorities should not be obliged pursuant to this Directive to procure works, supplies or services that are covered by a framework agreement, under that framework agreement. (62) It should also be clarified that, while contracts based on a framework agreement are to be awarded before the end of the term of the framework agreement itself, the duration of the individual contracts based on a framework agreement does not need to coincide with the duration of that framework agreement, but might, as appropriate, be shorter or longer. In particular, it should be allowed to set the length of individual contracts based on a framework agreement taking account of factors such as the time needed for their performance, where maintenance of equipment with an expected useful life of more than four years is included or where extensive training of staff to perform the contract is needed. It should also be clarified that there might be exceptional cases in which the length of the framework agreements themselves should be allowed to be longer than four years. Such cases, which should be duly justified, in particular by the subject of the framework agreement, might for instance arise where economic operators need to dispose of equipment the amortisation period of which is longer than four years and which must be available at any time over the entire duration of the framework agreement. (63) In view of the experience acquired, there is also a need to adjust the rules governing dynamic purchasing systems to enable contracting authorities to take full advantage of the possibilities afforded by that instrument. The systems need to be simplified; in particular they should be operated in the form of a restricted procedure, hence eliminating the need for indicative tenders, which have been identified as one of the major burdens associated with dynamic purchasing systems. Thus any economic operator that submits a request to participate and meets the selection criteria should be allowed to take part in procurement procedures carried out through the dynamic purchasing system over its period of validity. This purchasing technique allows the contracting authority to have a particularly broad range of tenders and hence to ensure optimum use of public funds through broad competition in respect of commonly used or off-the-shelf products, works or services which are generally available on the market. (64) The examination of those requests to participate should normally be performed within a maximum of 10 working days, given that the evaluation of the selection criteria will take place on the basis of the simplified requirements for documentation that are set out in this Directive. However, when a dynamic purchasing system is first set up, contracting authorities might, in response to the first publication of the contract notice or the invitation to confirm interest, be faced with such a large number of requests for participation that they would need more time to examine the requests. That should be admissible, provided that no specific procurement is launched before all the requests have been examined. Contracting authorities should be free to organise the way in which they intend to examine the requests for participation, for instance by deciding to conduct such examinations only once a week, provided the deadlines for the examination of each request of admission are observed. (65) At any time during the period of validity of the dynamic purchasing system, contracting authorities should be free to require economic operators to submit a renewed and updated self-declaration on the fulfilment of criteria for qualitative selection, within an adequate time limit. It should be recalled that the possibility foreseen in the general provisions on means of proof of this Directive to ask economic operators to submit supporting documents and the obligation to do so of the tenderer to which it has decided to award the contract also apply in the particular context of dynamic purchasing systems. (66) In order to further the possibilities of SMEs to participate in a large-scale dynamic purchasing system, for instance one that is operated by a central purchasing body, the contracting authority concerned should be able to articulate the system in objectively defined categories of products, works or services. Such categories should be defined by reference to objective factors which might for instance include the maximum allowable size of specific contracts to be awarded within the category concerned or a specific geographic area in which specific contracts are to be performed. Where a dynamic purchasing system is divided into categories, the contracting authority should apply selection criteria that are proportionate to the characteristics of the category concerned. (67) It should be clarified that electronic auctions are typically not suitable for certain public works contracts and certain public service contracts having as their subject-matter intellectual performances, such as the design of works, because only the elements suitable for automatic evaluation by electronic means, without any intervention or appreciation by the contracting authority, namely elements which are quantifiable so that they can be expressed in figures or percentages, may be the object of electronic auctions. It should, however, also be clarified that electronic auctions may be used in a procurement procedure for the purchase of a specific intellectual property right. It is also appropriate to recall that while contracting authorities remain free to reduce the number of candidates or tenderers as long as the auction has not yet started, no further reduction of the number of tenderers participating in the electronic auction should be allowed after the auction has started. (68) New electronic purchasing techniques are constantly being developed, such as electronic catalogues. Electronic catalogues are a format for the presentation and organisation of information in a manner that is common to all the participating bidders and which lends itself to electronic treatment. An example could be tenders presented in the form of a spreadsheet. Contracting authorities should be able to require electronic catalogues in all available procedures where the use of electronic means of communication is required. Electronic catalogues help to increase competition and streamline public purchasing, particularly in terms of savings in time and money. Certain rules should however be laid down to ensure that the use of the new techniques complies with this Directive and with the principles of equal treatment, non-discrimination and transparency. Thus, the use of electronic catalogues for the presentation of tenders should not entail the possibility of economic operators limiting themselves to the transmission of their general catalogue. Economic operators should still have to adapt their general catalogues in view of the specific procurement procedure. Such adaptation ensures that the catalogue that is transmitted in response to a given procurement procedure contains only products, works or services that the economic operators estimated - after an active examination - correspond to the requirements of the contracting authority. In so doing, economic operators should be allowed to copy information contained in their general catalogue, but they should not be allowed to submit the general catalogue as such. Furthermore, where sufficient guarantees are offered in respect of ensuring traceability, equal treatment and predictability, contracting authorities should be allowed to generate tenders in relation to specific purchases on the basis of previously transmitted electronic catalogues, in particular where competition has been reopened under a framework agreement or where a dynamic purchasing system is being used. Where tenders have been generated by the contracting authority, the economic operator concerned should be given the possibility to verify that the tender thus constituted by the contracting authority does not contain any material errors. Where material errors are present, the economic operator should not be bound by the tender generated by the contracting authority unless the error is corrected. In line with the requirements of the rules for electronic means of communication, contracting authorities should avoid unjustified obstacles to economic operators’ access to procurement procedures in which tenders are to be presented in the form of electronic catalogues and which guarantee compliance with the general principles of non-discrimination and equal treatment. (69) Centralised purchasing techniques are increasingly used in most Member States. Central purchasing bodies are responsible for making acquisitions, managing dynamic purchasing systems or awarding public contracts/framework agreements for other contracting authorities, with or without remuneration. The contracting authorities for whom a framework agreement is concluded should be able to use it for individual or repetitive purchases. In view of the large volumes purchased, such techniques may help increase competition and should help to professionalise public purchasing. Provision should therefore be made for a Union definition of central purchasing bodies dedicated to contracting authorities and it should be clarified that central purchasing bodies operate in two different manners. Firstly, they should be able to act as wholesalers by buying, stocking and reselling or, secondly, they should be able to act as intermediaries by awarding contracts, operating dynamic purchasing systems or concluding framework agreements to be used by contracting authorities. Such an intermediary role might in some cases be carried out by conducting the relevant award procedures autonomously, without detailed instructions from the contracting authorities concerned; in other cases, by conducting the relevant award procedures under the instructions of the contracting authorities concerned, on their behalf and for their account. Furthermore, rules should be laid down for allocating responsibility for the observance of the obligations pursuant to this Directive, as between the central purchasing body and the contracting authorities procuring from or through it. Where the central purchasing body has sole responsibility for the conduct of the procurement procedures, it should also be solely and directly responsible for the legality of the procedures. Where a contracting authority conducts certain parts of the procedure, for instance the reopening of competition under a framework agreement or the award of individual contracts based on a dynamic purchasing system, it should continue to be responsible for the stages it conducts. (70) Contracting authorities should be allowed to award a public service contract for the provision of centralised purchasing activities to a central purchasing body without applying the procedures provided for in this Directive. It should also be permitted for such public service contracts to include the provision of ancillary purchasing activities. Public service contracts for the provision of ancillary purchasing activities should, when performed otherwise than by a central purchasing body in connection with its provision of central purchasing activities to the contracting authority concerned, be awarded in accordance with this Directive. It should also be recalled that this Directive should not apply where centralised or ancillary purchasing activities are provided other than through a contract for pecuniary interest which constitutes procurement within the meaning of this Directive. (71) Strengthening the provisions concerning central purchasing bodies should in no way prevent the current practices of occasional joint procurement, i.e. less institutionalised and systematic common purchasing or the established practice of having recourse to service providers that prepare and manage procurement procedures on behalf and for the account of a contracting authority and under its instructions. On the contrary, certain features of joint procurement should be clarified because of the important role joint procurement may play, not least in connection with innovative projects. Joint procurement can take many different forms, ranging from coordinated procurement through the preparation of common technical specifications for works, supplies or services that will be procured by a number of contracting authorities, each conducting a separate procurement procedure, to situations where the contracting authorities concerned jointly conduct one procurement procedure either by acting together or by entrusting one contracting authority with the management of the procurement procedure on behalf of all contracting authorities. Where several contracting authorities are jointly conducting a procurement procedure, they should be jointly responsible for fulfilling their obligations under this Directive. However, where only parts of the procurement procedure are jointly conducted by the contracting authorities, joint responsibility should apply only to those parts of the procedure that have been carried out together. Each contracting authority should be solely responsible in respect of procedures or parts of procedures it conducts on its own, such as the awarding of a contract, the conclusion of a framework agreement, the operation of a dynamic purchasing system, the reopening of competition under a framework agreement or the determination of which of the economic operators party to a framework agreement shall perform a given task. (72) Electronic means of communication are particularly well suited to supporting centralised purchasing practices and tools because of the possibility they offer to re-use and automatically process data and to minimise information and transaction costs. The use of such electronic means of communication should therefore, as a first step, be rendered compulsory for central purchasing bodies, while also facilitating converging practices across the Union. This should be followed by a general obligation to use electronic means of communication in all procurement procedures after a transition period of 30 months. (73) Joint awarding of public contracts by contracting authorities from different Member States currently encounters specific legal difficulties concerning conflicts of national laws. Despite the fact that Directive 2004/18/EC implicitly allowed for cross-border joint public procurement, contracting authorities are still facing considerable legal and practical difficulties in purchasing from central purchasing bodies in other Member States or jointly awarding public contracts. In order to allow contracting authorities to derive maximum benefit from the potential of the internal market in terms of economies of scale and risk-benefit sharing, not least for innovative projects involving a greater amount of risk than reasonably bearable by a single contracting authority, those difficulties should be remedied. Therefore new rules on cross-border joint procurement should be established in order to facilitate cooperation between contracting authorities and enhancing the benefits of the internal market by creating cross-border business opportunities for suppliers and service providers. Those rules should determine the conditions for cross-border utilisation of central purchasing bodies and designate the applicable public procurement legislation, including the applicable legislation on remedies, in cases of cross-border joint procedures, complementing the conflict of law rules of Regulation (EC) No 593/2008 of the European Parliament and the Council ( 13 ). In addition, contracting authorities from different Member States should be able to set up joint entities established under national or Union law. Specific rules should be established for such forms of joint procurement. However, contracting authorities should not make use of the possibilities for cross-border joint procurement for the purpose of circumventing mandatory public law rules, in conformity with Union law, which are applicable to them in the Member State where they are located. Such rules might include, for example, provisions on transparency and access to documents or specific requirements for the traceability of sensitive supplies. (74) The technical specifications drawn up by public purchasers need to allow public procurement to be open to competition as well as to achieve objectives of sustainability. To that end, it should be possible to submit tenders that reflect the diversity of technical solutions standards and technical specifications in the marketplace, including those drawn up on the basis of performance criteria linked to the life cycle and the sustainability of the production process of the works, supplies and services. Consequently, technical specifications should be drafted in such a way as to avoid artificially narrowing down competition through requirements that favour a specific economic operator by mirroring key characteristics of the supplies, services or works habitually offered by that economic operator. Drawing up the technical specifications in terms of functional and performance requirements generally allows that objective to be achieved in the best way possible. Functional and performance-related requirements are also appropriate means to favour innovation in public procurement and should be used as widely as possible. Where reference is made to a European standard or, in the absence thereof, to a national standard, tenders based on equivalent arrangements should be considered by contracting authorities. It should be the responsibility of the economic operator to prove equivalence with the requested label. To prove equivalence, it should be possible to require tenderers to provide third-party verified evidence. However, other appropriate means of proof such as a technical dossier of the manufacturer should also be allowed where the economic operator concerned has no access to such certificates or test reports, or no possibility of obtaining them within the relevant time limits, provided that the economic operator concerned thereby proves that the works, supplies or services meet the requirements or criteria set out in the technical specifications, the award criteria or the contract performance conditions. (75) Contracting authorities that wish to purchase works, supplies or services with specific environmental, social or other characteristics should be able to refer to particular labels, such as the European Eco-label, (multi-)national eco-labels or any other label provided that the requirements for the label are linked to the subject-matter of the contract, such as the description of the product and its presentation, including packaging requirements. It is furthermore essential that those requirements are drawn up and adopted on the basis of objectively verifiable criteria, using a procedure in which stakeholders, such as government bodies, consumers, manufacturers, distributors and environmental organisations, can participate, and that the label is accessible and available to all interested parties. It should be clarified that stakeholders could be public or private bodies, businesses or any sort of non-governmental organisation (an organisation that is not a part of a government and is not a conventional business). It should equally be clarified that specific national or government bodies or organisations can be involved in setting up label requirements that may be used in connection with procurement by public authorities without those bodies or organisations losing their status as third parties. References to labels should not have the effect of restricting innovation. (76) For all procurement intended for use by persons, whether general public or staff of the contracting authority, it is necessary for contracting authorities to lay down technical specifications so as to take into account accessibility criteria for people with disabilities or design for all users, except in duly justified cases. (77) When drawing up technical specifications, contracting authorities should take into account requirements ensuing from Union law in the field of data protection law, in particular in relation to the design of the processing of personal data (data protection by design). (78) Public procurement should be adapted to the needs of SMEs. Contracting authorities should be encouraged to make use of the Code of Best Practices set out in the Commission Staff Working Document of 25 June 2008 entitled ‘European Code of Best Practices Facilitating Access by SMEs to Public Procurement Contracts’, providing guidance on how they may apply the public procurement framework in a way that facilitates SME participation. To that end and to enhance competition, contracting authorities should in particular be encouraged to divide large contracts into lots. Such division could be done on a quantitative basis, making the size of the individual contracts better correspond to the capacity of SMEs, or on a qualitative basis, in accordance with the different trades and specialisations involved, to adapt the content of the individual contracts more closely to the specialised sectors of SMEs or in accordance with different subsequent project phases. The size and subject-matter of the lots should be determined freely by the contracting authority, which, in accordance with the relevant rules on the calculation of the estimated value of procurement, should also be allowed to award some of the lots without applying the procedures of this Directive. The contracting authority should have a duty to consider the appropriateness of dividing contracts into lots while remaining free to decide autonomously on the basis of any reason it deems relevant, without being subject to administrative or judicial supervision. Where the contracting authority decides that it would not be appropriate to divide the contract into lots, the individual report or the procurement documents should contain an indication of the main reasons for the contracting authority’s choice. Such reasons could for instance be that the contracting authority finds that such division could risk restricting competition, or risk rendering the execution of the contract excessively technically difficult or expensive, or that the need to coordinate the different contractors for the lots could seriously risk undermining the proper execution of the contract. Member States should remain free to go further in their efforts to facilitate the involvement of SMEs in the public procurement market, by extending the scope of the obligation to consider the appropriateness of dividing contracts into lots to smaller contracts, by requiring contracting authorities to provide a justification for a decision not to divide contracts into lots or by rendering a division into lots obligatory under certain conditions. With the same purpose, Member States should also be free to provide mechanisms for direct payments to subcontractors. (79) Where contracts are divided into lots, contracting authorities should, for instance in order to preserve competition or to ensure reliability of supply, be allowed to limit the number of lots for which an economic operator may tender; they should also be allowed to limit the number of lots that may be awarded to any one tenderer. However, the objective of facilitating greater access to public procurement by SMEs might be hampered if contracting authorities would be obliged to award the contract lot by lot even where this would entail having to accept substantially less advantageous solutions compared to an award grouping several or all of the lots. Where the possibility to apply such a method has been clearly indicated beforehand, it should therefore be possible for contracting authorities to conduct a comparative assessment of the tenders in order to establish whether the tenders submitted by a particular tenderer for a specific combination of lots would, taken as whole, fulfil the award criteria laid down in accordance with this Directive with regard to those lots better than the tenders for the individual lots concerned seen in isolation. If so, the contracting authority should be allowed to award a contract combining the lots in question to the tenderer concerned. It should be clarified that contracting authorities should conduct such a comparative assessment by first determining which tenders best fulfil the award criteria laid down for each individual lot and then comparing it with the tenders submitted by a particular tenderer for a specific combination of lots, taken as a whole. (80) In order to make procedures faster and more efficient, time limits for participation in procurement procedures should be kept as short as possible without creating undue barriers to access for economic operators from across the internal market and in particular SMEs. It should therefore be kept in mind that, when fixing the time limits for the receipt of tenders and requests to participate, contracting authorities should take account in particular of the complexity of the contract and the time required to draw up tenders, even if this entails setting time limits that are longer than the minima provided for under this Directive. The use of electronic means of information and communication, in particular full electronic availability to economic operators, tenderers and candidates of procurement documents and electronic transmission of communications leads, on the other hand, to increased transparency and time savings. Therefore, provision should be made for reducing the minimum time limits in line with the rules set by the GPA and subject to the condition that they are compatible with the specific mode of transmission envisaged at Union level. Furthermore, contracting authorities should have the opportunity to further shorten the time limits for receipt of requests to participate and of tenders in cases where a state of urgency renders the regular time limits impracticable, but does not make a regular procedure with publication impossible. Only in exceptional situations where extreme urgency brought about by events unforeseeable by the contracting authority concerned that are not attributable to that contracting authority makes it impossible to conduct a regular procedure even with shortened time limits, contracting authorities should, in so far as strictly necessary, have the possibility to award contracts by negotiated procedure without prior publication. This might be case where natural catastrophes require immediate action. (81) It should be clarified that the need to ensure that economic operators have sufficient time in which to draw up responsive tenders may entail that the time limits which were set initially may have to be extended. This would, in particular, be the case where significant changes are made to the procurement documents. It should also be specified that, in that case, significant changes should be understood as covering changes, in particular to the technical specifications, in respect of which economic operators would need additional time in order to understand and respond appropriately. It should, however, be clarified that such changes should not be so substantial that the admission of candidates other than those initially selected would have been allowed for or additional participants in the procurement procedure would have been attracted. That could, in particular, be the case where the changes render the contract or the framework agreement materially different in character from the one initially set out in the procurement documents. (82) It should be clarified that the information concerning certain decisions taken during a procurement procedure, including the decision not to award a contract or not to conclude a framework agreement, should be sent by the contracting authorities, without candidates or tenderers having to request such information. It should also be recalled that Council Directive 89/665/EEC ( 14 ) provides for an obligation for contracting authorities, again without candidates or tenderer having to request it, to provide the candidates and tenderers concerned with a summary of the relevant reasons for some of the central decisions that are taken in the course of a procurement procedure. It should finally be clarified that candidates and tenderers should be able to request more detailed information concerning those reasons, which contracting authorities should be required to give except where there would be serious grounds for not doing so. Those grounds should be set out in this Directive. To ensure the necessary transparency in the context of procurement procedures involving negotiations and dialogues with tenderers, tenderers having made an admissible tender should, except where there would be serious grounds for not doing so, also be enabled to request information on the conduct and progress of the procedure. (83) Overly demanding requirements concerning economic and financial capacity frequently constitute an unjustified obstacle to the involvement of SMEs in public procurement. Any such requirements should be related and proportionate to the subject-matter of the contract. In particular, contracting authorities should not be allowed to require economic operators to have a minimum turnover that would be disproportionate to the subject-matter of the contract; the requirement should normally not exceed at the most twice the estimated contract value. However, in duly justified circumstances, it should be possible to apply higher requirements. Such circumstances might relate to the high risks attached to the performance of the contract or the fact that its timely and correct performance is critical, for instance because it constitutes a necessary preliminary for the performance of other contracts. In such duly justified cases contracting authorities should remain free to decide autonomously whether higher minimum turnover requirements would be appropriate and pertinent without being subject to administrative or judicial supervision. Where higher minimum turnover requirements are to be applied, contracting authorities should remain free to set the level as long as it is related and proportionate to the subject-matter of the contract. Where the contracting authority decides that the minimum turnover requirement should be set at a level higher than twice the estimated contract value, the individual report or the procurement documents should contain an indication of the main reasons for the contracting authority’s choice. Contracting authorities should also be able to request information on the ratios, for instance, between assets and liabilities in the annual accounts. A positive ratio showing higher levels of assets than of liabilities could provide additional evidence that the financial capacity of economic operators is sufficient. (84) Many economic operators, and not least SMEs, find that a major obstacle to their participation in public procurement consists in administrative burdens deriving from the need to produce a substantial number of certificates or other documents related to exclusion and selection criteria. Limiting such requirements, for example through use of a European Single Procurement Document (ESPD) consisting of an updated self-declaration, could result in considerable simplification for the benefit of both contracting authorities and economic operators. The tenderer to which it has been decided to award the contract should, however, be required to provide the relevant evidence and contracting authorities should not conclude contracts with tenderers unable to do so. Contracting authorities should also be entitled to request all or part of the supporting documents at any moment where they consider this to be necessary in view of the proper conduct of the procedure. This might in particular be the case in two-stage procedures – restricted procedures, competitive procedures with negotiation, competitive dialogues and innovation partnerships - in which the contracting authorities make use of the possibility to limit the number of candidates invited to submit a tender. Requiring submission of the supporting documents at the moment of selection of the candidates to be invited could be justified to avoid that contracting authorities invite candidates which later prove unable to submit the supporting documents at the award stage, depriving otherwise qualified candidates from participation. It should be set out explicitly that the ESPD should also provide the relevant information in respect of entities on whose capacities an economic operator relies, so that the verification of the information regarding such entities can be carried out together with and on the same conditions as the verification in respect of the main economic operator. (85) It is important that the decisions of contracting authorities should be based on recent information, in particular as regards exclusion grounds, given that important changes can intervene quite rapidly, for instance in the event of financial difficulties which would render the economic operator unsuitable or, conversely, because an outstanding debt on social contributions would meanwhile have been paid. It is therefore preferable that, whenever possible, contracting authorities should verify such information by accessing relevant databases, which should be national in the sense of being administered by public authorities. At the current stage of development, there might still be cases where doing so is not yet possible because of technical reasons. The Commission should therefore envisage promoting measures that could facilitate easy recourse to up-to-date information electronically, such as strengthening tools offering access to virtual company dossiers, or means of facilitating interoperability between databases or other such flanking measures. It should also be provided that contracting authorities should not ask for still up-to-date documents, which they already possess from earlier procurement procedures. However, it should also be ensured that contracting authorities will not be faced with disproportionate archiving and filing burdens in this context. Consequently, implementation of this duty should only be applicable once the use of electronic means of communication is obligatory, as electronic document management will render the task much easier for contracting authorities. (86) Further simplification for both economic operators and contracting authorities could be obtained by means of a standard form for self-declarations, which could reduce problems linked to the precise drafting of formal statements and declarations of consent as well as language issues. (87) The Commission provides and manages an electronic system, e-Certis, which is currently updated and verified on a voluntary basis by national authorities. The aim of e-Certis is to facilitate the exchange of certificates and other documentary evidence frequently required by contracting authorities. Experience acquired so far indicates that voluntary updating and verification is insufficient to ensure that e-Certis can deliver its full potential for simplifying and facilitating documentary exchanges for the benefit of SMEs in particular. Maintenance should therefore be rendered obligatory in a first step. Recourse to e-Certis will be made mandatory at a later stage. (88) Contracting authorities should be able to require that environmental management measures or schemes be applied during the performance of a public contract. Environmental management schemes, whether or not they are registered under Union instruments such as Regulation (EC) No 1221/2009 of the European Parliament and of the Council ( 15 ), can demonstrate that the economic operator has the technical capability to perform the contract. This includes Ecolabel certificates involving environmental management criteria. Where an economic operator has no access to such environmental management registration schemes or no possibility of obtaining them within the relevant time limits, it should be allowed to submit a description of the environmental management measures implemented, provided that the economic operator concerned demonstrates that those measures ensure the same level of environmental protection as the measures required under the environmental management. (89) The notion of award criteria is central to this Directive. It is therefore important that the relevant provisions be presented in as simple and streamlined a way as possible. This can be obtained by using the terminology ‘most economically advantageous tender’ as the overriding concept, since all winning tenders should finally be chosen in accordance with what the individual contracting authority considers to be the economically best solution among those offered. In order to avoid confusion with the award criterion that is currently known as the ‘most economically advantageous tender’ in Directives 2004/17/EC and 2004/18/EC, a different terminology should be used to cover that concept, the ‘best price-quality ratio’. Consequently, it should be interpreted in accordance with the case-law relating to those Directives, except where there is a clearly materially different solution in this Directive. (90) Contracts should be awarded on the basis of objective criteria that ensure compliance with the principles of transparency, non-discrimination and equal treatment, with a view to ensuring an objective comparison of the relative value of the tenders in order to determine, in conditions of effective competition, which tender is the most economically advantageous tender. It should be set out explicitly that the most economically advantageous tender should be assessed on the basis of the best price-quality ratio, which should always include a price or cost element. It should equally be clarified that such assessment of the most economically advantageous tender could also be carried out on the basis of either price or cost effectiveness only. It is furthermore appropriate to recall that contracting authorities are free to set adequate quality standards by using technical specifications or contract performance conditions. In order to encourage a greater quality orientation of public procurement, Member States should be permitted to prohibit or restrict use of price only or cost only to assess the most economically advantageous tender where they deem this appropriate. To ensure compliance with the principle of equal treatment in the award of contracts, contracting authorities should be obliged to create the necessary transparency to enable all tenderers to be reasonably informed of the criteria and arrangements which will be applied in the contract award decision. Contracting authorities should therefore be obliged to indicate the contract award criteria and the relative weighting given to each of those criteria. Contracting authorities should, however, be permitted to derogate from that obligation to indicate the weighting of the criteria in duly justified cases for which they must be able to give reasons, where the weighting cannot be established in advance, in particular because of the complexity of the contract. In such cases, they should indicate the criteria in decreasing order of importance. (91) Article 11 TFEU requires that environmental protection requirements be integrated into the definition and implementation of the Union policies and activities, in particular with a view to promoting sustainable development. This Directive clarifies how the contracting authorities can contribute to the protection of the environment and the promotion of sustainable development, whilst ensuring that they can obtain the best value for money for their contracts. (92) When assessing the best price-quality ratio contracting authorities should determine the economic and qualitative criteria linked to the subject-matter of the contract that they will use for that purpose. Those criteria should thus allow for a comparative assessment of the level of performance offered by each tender in the light of the subject-matter of the contract, as defined in the technical specifications. In the context of the best price-quality ratio, a non-exhaustive list of possible award criteria which include environmental and social aspects is set out in this Directive. Contracting authorities should be encouraged to choose award criteria that allow them to obtain high-quality works, supplies and services that are optimally suited to their needs. The chosen award criteria should not confer an unrestricted freedom of choice on the contracting authority and they should ensure the possibility of effective and fair competition and be accompanied by arrangements that allow the information provided by the tenderers to be effectively verified. To identify the most economically advantageous tender, the contract award decision should not be based on non-cost criteria only. Qualitative criteria should therefore be accompanied by a cost criterion that could, at the choice of the contracting authority, be either the price or a cost-effectiveness approach such as life-cycle costing. However, the award criteria should not affect the application of national provisions determining the remuneration of certain services or setting out fixed prices for certain supplies. (93) Where national provisions determine the remuneration of certain services or set out fixed prices for certain supplies, it should be clarified that it remains possible to assess value for money on the basis of other factors than solely the price or remuneration. Depending on the service or product concerned, such factors could, for instance, include conditions of delivery and payment, aspects of after-sale service (e.g. the extent of advisory and replacement services) or environmental or social
