Works Contract

A works contract is a public contract having as its object the execution of building or civil engineering works listed in Annex II to Directive 2014/24/EU, or the realization by any means of a work corresponding to the requirements specified by the contracting authority. Defined by Article 2(1)(6) of Directive 2014/24/EU, works contracts are one of the three main categories of public contract (alongside supply contracts and service contracts) and are subject to the highest EU threshold — EUR 5,538,000 for the 2024-2025 period — reflecting the typically large scale and complexity of construction projects. Works contracts represent a significant portion of total public procurement expenditure across the EU, encompassing everything from highway construction and bridge rehabilitation to school building and water treatment plant installation.

How It Works

Works contracts are distinguished from supply and service contracts by their object: the physical construction, alteration, repair, or demolition of buildings and infrastructure. The directive draws an important distinction between "works" (individual construction activities) and "a work" (a complete functional result):

"Works" refers to the individual building or civil engineering activities listed in Annex II to the directive, which corresponds to Division 45 of the NACE classification (Statistical Classification of Economic Activities). These include:

Site preparation and demolition
Building of complete constructions or parts thereof
Civil engineering (roads, bridges, tunnels, railways, airports, harbors)
Building installation (electrical, plumbing, heating, ventilation)
Building completion and finishing (plastering, painting, glazing, floor covering)

"A work" refers to the outcome of building or civil engineering works taken as a whole that is sufficient in itself to fulfill an economic or technical function. A "work" is the complete result — a functional building, a usable bridge, a operational water treatment plant — as opposed to individual construction activities. This distinction matters because a contracting authority that procures individual trades separately (electrical, plumbing, structural) is procuring "works," while an authority that procures the design and construction of a complete building is procuring "a work."

The classification of a contract as a works contract rather than a supply or service contract has several important consequences:

Higher threshold. The works threshold (EUR 5,538,000) is substantially higher than the supply and service thresholds (EUR 143,000 for central government, EUR 221,000 for sub-central). This means many works contracts fall below the EU threshold and are governed only by national procurement rules.
Longer minimum time limits. Works contracts, particularly those using the restricted procedure, may benefit from extended time limits to allow contractors adequate preparation time for complex bids.
Specific selection criteria. Contracting authorities typically require contractors to demonstrate specific works experience, financial capacity for the project's scale, health and safety records, and relevant professional qualifications (e.g., registration in professional construction registers).
Subcontracting provisions. Article 71 contains specific provisions on subcontracting that are particularly relevant to works contracts, including the right of contracting authorities to require disclosure of subcontractors, verify that subcontractors are not subject to exclusion grounds, and require direct payment to subcontractors.
CPV classification. Works contracts are classified under CPV Division 45 (Construction work), with codes ranging from 45000000 to 45999999. The CPV code helps identify the specific type of construction work (building construction, civil engineering, installation, completion).

The procurement of works contracts often involves additional complexity compared to supply and service contracts:

Design and build vs. traditional procurement. In traditional procurement, the authority provides a complete design, and contractors bid on execution. In design-and-build, the authority specifies requirements, and contractors propose both design and execution. Design-and-build is increasingly common for complex projects and may use competitive dialogue or the competitive procedure with negotiation.
Lot division. Article 46 of the directive requires contracting authorities to consider dividing contracts into lots, particularly to facilitate access for SMEs. In works procurement, lot division might follow geographic boundaries (sections of a highway), trades (electrical, mechanical, structural), or project phases.
Framework agreements. Some contracting authorities use framework agreements for recurring works (maintenance, minor repairs, rehabilitation) to streamline procurement and ensure rapid response capability.

Legal Framework

Article 2(1)(6) of Directive 2014/24/EU defines public works contracts as "public contracts having as their object one of the following: (a) the execution, or both the design and execution, of works related to one of the activities within the meaning of Annex II; (b) the execution, or both the design and execution, of a work; (c) the realisation, by whatever means, of a work corresponding to the requirements specified by the contracting authority exercising a decisive influence on the type or design of the work."

Annex II lists the activities that constitute "works" by reference to the NACE classification Division 45, encompassing all building and civil engineering activities.

Article 2(1)(7) defines "work" as "the outcome of building or civil engineering works taken as a whole which is sufficient in itself to fulfil an economic or technical function."

Article 4(a) sets the works threshold at EUR 5,538,000 (2024-2025 period, reviewed every two years).

Article 5(8) provides specific rules for estimating the value of works contracts: the estimated value must include both the cost of the works and the estimated total value of supplies and services needed for the execution, where these are made available by the contracting authority.

Article 46 (division into lots) is particularly relevant to works, as construction projects can often be logically divided into geographic or trade-based lots.

Article 71 addresses subcontracting in works contracts, allowing authorities to require information about subcontractors, verify their compliance with exclusion grounds, and establish direct payment arrangements.

National transpositions include specific works procurement provisions:

Germany: The VOB (Vergabe- und Vertragsordnung fur Bauleistungen) provides detailed rules for construction procurement, including the VOB/A (procurement procedure), VOB/B (contract conditions), and VOB/C (technical specifications).
France: The Code de la commande publique and the CCAG-Travaux (Cahier des Clauses Administratives Generales Travaux) provide the contractual framework for public works.
Netherlands: The Aanbestedingswet 2012, supplemented by the UAV (Uniforme Administratieve Voorwaarden) for traditional works and the UAV-GC for integrated contracts (design-build).
United Kingdom: The NEC (New Engineering Contract) suite is widely used for public works procurement.

Practical Examples

Example 1: Highway Construction. A national roads authority procures the construction of a 25-km highway bypass valued at EUR 180 million. The contract includes earthworks, road pavement, bridges, drainage, signage, and landscaping. The authority uses a restricted procedure, pre-qualifying contractors based on experience with similar highway projects (minimum three projects of EUR 50 million+ in the past 10 years), financial standing, and health and safety record. The MEAT evaluation weights price at 40%, construction methodology at 25%, programme and traffic management at 20%, and environmental management at 15%.

Example 2: School Renovation. A municipality procures the energy renovation of five primary schools. Each school is a separate lot, valued at EUR 800,000 to EUR 1.2 million. The aggregate value (EUR 5 million) is below the works threshold (EUR 5,538,000), so the full EU directive procedures do not apply. However, under Article 5(10), where the value of an individual lot exceeds EUR 1 million for works, the directive still applies to that lot. The municipality applies national procurement rules to all lots, as permitted by Article 5(10) where the aggregate value of exempted lots does not exceed 20% of the total.

Example 3: Design-Build Water Treatment Plant. A water utility procures the design and construction of a new water treatment plant valued at EUR 45 million. The authority uses competitive dialogue, inviting pre-qualified consortia to develop designs through multiple dialogue rounds. Each consortium includes an engineering design firm, a construction contractor, and a specialist equipment supplier. The final tenders propose different treatment technologies (membrane filtration vs. conventional rapid gravity filtration), and the evaluation assesses treatment performance, life-cycle cost, buildability, and construction programme.

Key Considerations for Suppliers

Build a strong works reference portfolio. Works procurement places heavy emphasis on track record. Contracting authorities typically require references for similar completed projects within the past 5-10 years, with specific minimum values and technical characteristics. Maintain a comprehensive database of completed projects with certificates of satisfactory completion, final account values, and contact details for client references.

Understand the subcontracting landscape. Major works contracts are rarely delivered by a single contractor. Specialist subcontractors (electrical, mechanical, structural steelwork, piling, facade) are essential. Whether you are a main contractor or a subcontractor, understand the subcontracting provisions: Article 71 requires transparency about subcontractors, and many contracting authorities increasingly require that key subcontractors be named in the tender and meet the same exclusion and qualification standards as the main contractor.

Plan for the works threshold implications. At EUR 5,538,000, the works threshold is substantially higher than for supplies or services. Many works contracts fall below the EU threshold, meaning they are governed by national rules that may be more or less stringent than the directive. If you operate across multiple countries, understand the national procurement rules for below-threshold works in each jurisdiction.

Invest in BIM and digital construction capabilities. Building Information Modelling (BIM) is increasingly required or valued in public works procurement, particularly in northern European countries. The UK, the Netherlands, and the Nordic countries frequently mandate BIM at specified levels of maturity. Digital construction capabilities (BIM, 4D scheduling, drone surveying, digital twins) are becoming award criteria rather than optional extras.

Price carefully and manage risk. Works contracts involve significant uncertainty: ground conditions, weather, material price fluctuations, labor availability, and design changes all affect costs. Ensure your pricing includes appropriate contingencies and that you understand the contractual risk allocation. Fixed-price contracts place more risk on the contractor; cost-reimbursable contracts place more risk on the client. Most public works contracts use fixed-price or target-cost models with defined change management procedures.

Public Contract — The general category of contracts; works contracts are one of three types.
Works — The building and civil engineering activities that form the object of a works contract.
Procedure — The procurement process used to award works contracts; restricted and competitive dialogue are common for complex works.
Lot — Works contracts are frequently divided into geographic or trade-based lots.
CPV — Works are classified under CPV Division 45 (45000000-45999999).
EU Threshold — The works threshold (EUR 5,538,000) is the highest of the three contract type thresholds.

Frequently Asked Questions

Why is the works threshold higher than the supply and service thresholds?

The higher works threshold reflects the nature of construction projects: they are inherently local (requiring physical presence at the construction site), involve significant mobilization costs that would be disproportionate for smaller projects, and have limited cross-border interest for lower-value contracts. A construction project in a remote area of Portugal is unlikely to attract bidders from Finland unless the contract is very large. The higher threshold ensures that only the largest works contracts — where cross-border competition is realistic and the administrative cost of EU procedures is proportionate — are subject to the full directive requirements.

The distinction depends on the primary object of the contract. A contract for the physical execution of building or civil engineering works (construction, installation, renovation, demolition) is a works contract. A contract for design services (architecture, engineering, surveying), supervision, project management, or consultancy related to construction is a service contract. A design-and-build contract — which combines both design services and works execution — is classified according to the main object: if the works element is the larger component (which is almost always the case), it is a works contract.

Can an SME win a works contract?

Yes. EU policy actively promotes SME participation in works procurement. Article 46 requires authorities to consider dividing contracts into lots to facilitate SME access. Many works contracts are divided into trade lots (electrical, mechanical, finishing) that are accessible to specialist SMEs. Additionally, the Article 5(10) exemption for small lots (below EUR 1 million for works) may allow simplified procurement rules for smaller packages. SMEs that cannot compete for main contractor roles can participate as named subcontractors, gaining experience and references for future direct bids.
