Quick answer
A works contract is a public procurement agreement for the execution, or both the design and execution, of construction or civil engineering activities. It is one of the three main contract types under EU procurement law, alongside supply and services contracts.
A works contract is the foundational procurement vehicle for construction, civil engineering, and infrastructure projects in the European public sector. Understanding its legal definition matters because the classification of a contract as a works contract triggers specific EU and national procurement rules, including mandatory advertising thresholds and procedural requirements distinct from those that apply to goods or services.
What is a Works Contract?
Article 2(1)(6) of Directive 2014/24/EU defines a works contract as a public contract having as its object one of three things: the execution of works related to one of the activities listed in Annex II (which includes construction and civil engineering categories); the execution and design of such works; or the realisation of a work by any means corresponding to the requirements specified by the contracting authority.
The EU threshold for works contracts is substantially higher than for supplies or services. As of recent updates, the threshold stands at EUR 5,382,000 for most contracting authorities, meaning that contracts below this value are governed by national rules only, while those at or above it must follow the full Directive 2014/24/EU procedure.
In the UK, following the end of the transition period, the Procurement Act 2023 similarly treats works contracts as a distinct category with a separate financial threshold, currently set at GBP 5,372,609.
A works contract is not the same as a public works concession. In a concession, the operator assumes the operational and demand risk; in a standard works contract, the contracting authority pays directly for the completed works and bears the performance and payment risk itself.
Works contracts frequently incorporate a bill of quantities (BOQ) as the pricing mechanism, allowing for transparent comparison of contractor bids and clear variation management during construction.
Why it matters for bidders
Correctly identifying a tender as a works contract, rather than a services contract, tells you which rules govern the process: which CPV codes apply, what selection and technical capacity requirements may be imposed, and whether the contract will use a standard construction form such as NEC, FIDIC, or JCT.
Bidders should also recognise that works contracts typically carry distinct contractual risk allocations, including provisions for retention, practical completion, and a defects liability period, none of which feature in typical supply or service agreements.
Example
A Dutch municipality wishes to build a new sports centre. The contract covers both the detailed design and the construction of the building. Because the estimated value exceeds the EU works threshold and encompasses both design and execution, it is classified as a works contract under Directive 2014/24/EU and must be advertised in the Supplement to the Official Journal of the EU (TED).
Frequently Asked Questions
How does a works contract differ from a services contract for construction-related work?
A contract for construction supervision, project management, or architectural services is a services contract, not a works contract. A works contract requires the contractor to physically execute the works. Where a single contract bundles both design and execution, it is still treated as a works contract if the works element predominates by value.
Are maintenance contracts treated as works contracts?
General maintenance services (cleaning, routine servicing) are services contracts. Substantial maintenance that amounts to renovation, rebuilding, or significant structural work may qualify as a works contract. The test is whether the activity falls within the CPV codes and activities listed in Annex II to Directive 2014/24/EU.
What procurement procedures are available for works contracts?
Open procedure, restricted procedure, competitive procedure with negotiation, competitive dialogue, and innovation partnership are all available. The open and restricted procedures are the most common for works contracts. For highly complex or technically uncertain infrastructure projects, competitive dialogue is increasingly used.

Public Works Concession
A public works concession is a contract under which a contracting authority grants the right to exploit a constructed work to an operator, with the key distinction that the operator assumes the operating risk, including demand and availability risk, rather than receiving direct payment for completed works.
ViewConstruction Procurement (EU)
Construction procurement in the EU refers to the regulated process by which public authorities acquire building, civil engineering, and infrastructure works, governed primarily by Directive 2014/24/EU for standard works contracts and Directive 2014/23/EU for concessions, with mandatory advertising above defined financial thresholds.
ViewBill of Quantities (BOQ)
A bill of quantities is a structured pricing document prepared by a quantity surveyor that itemises all the materials, labour, and operations required to complete a construction project, enabling contractors to submit comparable tenders and providing a basis for valuing variations and interim payments during the works.
ViewNEC Contract (New Engineering Contract)
The NEC contract suite is a family of standard construction and engineering contracts published by the Institution of Civil Engineers, designed around collaborative management principles, early warning mechanisms, and clear risk allocation, widely used by UK public authorities and increasingly adopted across Europe for major infrastructure projects.
ViewFIDIC Contract
FIDIC contracts are a suite of internationally recognised standard conditions of contract for construction and engineering projects, published by the International Federation of Consulting Engineers, widely used for cross-border infrastructure projects in Europe and for works financed by multilateral development banks.
