Construction Contracts in the Netherlands

Published on 20 March 2026 · Last updated 25 October 2026

Under Dutch law, a construction contract is in principle a contract for work (aanneming van werk): the contractor undertakes to build and deliver a tangible work, outside an employment relationship, for a price in money (Article 7:750 Dutch Civil Code, DCC). Articles 7:750-7:769 DCC govern the price, extra work, completion and defects. Our Dutch construction lawyers explain what to check.

There is no separate construction contracts act: the rules are in Title 7.12 of the Dutch Civil Code and apply to traditional contracts as well as to design and build. A contract for work can in principle be concluded in any form (Article 3:37(1) DCC), unless the law provides otherwise. For example, a contract with a consumer for the construction of a house must be in writing, unless the house is built on land the consumer already owns and the contract is not connected with the purchase of that land (Article 7:766 DCC). In practice, parties add standard terms such as the UAV 2012 or the UAV-GC.

Since 1 January 2024, the Quality Assurance for Building Act (Wet kwaliteitsborging voor het bouwen, Wkb) has changed several rules for building works (bouwwerken). The contractor is now liable for defects not discovered at completion, unless they cannot be attributed to it (Article 7:758(4) DCC). If the client is not a consumer, this rule can only be departed from if the contract expressly says so. It only applies to contracts concluded on or after 1 January 2024 (Article 218(1) Transitional Act for the new Civil Code). Modern construction contracts often combine design, construction and maintenance in one contract.

What Contract Forms Exist in Dutch Construction Law?

Three main contract forms are used in Dutch construction: the traditional model, in which the client provides the design and the contractor builds it; the construction team (bouwteam), in which the contractor advises during the design phase; and integrated contracts such as design and build (D&B), in which one contractor is responsible for both design and execution.

In the traditional model, the client has the design made by an architect or engineer, after which a contractor builds the work according to the specifications (bestek). The contractor must warn the client of errors in the assignment that it knew or should reasonably have known, including errors in plans, drawings and specifications provided by the client (Article 7:754(1) DCC). The consequences of errors in such client-supplied documents are in principle for the client’s account, unless the contractor breached its duty to warn or otherwise fell short in expertise or care (Article 7:760(2) and (3) DCC). The drawback of this model is that the contractor’s execution knowledge is not used during the design.

Construction Team Collaboration for Optimal Coordination

In a construction team (bouwteam), the contractor joins the client and the designer during the design phase and contributes its execution knowledge. This allows technical problems to be identified earlier. Whether the contractor will then also receive the construction contract depends on what the parties have agreed. They usually record the cooperation, the fee for the design phase and the procedure for pricing the execution in a separate bouwteam agreement.

Integrated Contract Models from International Practice Under Dutch Law

Integrated contracts combine design and construction, and sometimes financing, maintenance or operation, in one contract with one contractor. Examples are design and build (D&B) or design and construct (D&C), turnkey contracts, DBFM (design, build, finance, maintain) and BOT (build, operate, transfer) contracts, the latter mainly in public-private partnerships.

For the client, an integrated contract means one point of contact for the whole project. The contractor is responsible for the design it makes itself: the rule that the consequences of errors in designs are for the client’s account (Article 7:760(3) DCC) only concerns designs that the client provides. For integrated contracts, parties can use the UAV-GC standard terms (see below).

How Does Subcontracting Work in Dutch Construction Law?

A contractor may have the work carried out by others, such as subcontractors (onderaannemers), under its direction, but it remains liable to the client for proper performance of the contract (Article 7:751 DCC). Back-to-back contracting means passing on obligations from the main contract to the subcontracts, so that risks and responsibilities are aligned along the chain.

Main contractors regularly engage subcontractors for specialised work such as installations or foundations. The client has no contract with the subcontractor, so under the contract it holds the main contractor liable for the subcontractor’s work. The main contractor therefore tries to pass on its own obligations in the subcontracts.

Legal Complexity of Back-to-Back Clauses in the Netherlands

A general clause stating that the subcontractor is deemed familiar with the main contract offers little certainty and can lead to construction disputes. It is safer to include the specific obligations, deadlines and standards in the subcontract itself. If the subcontract refers to general terms and conditions, the user must give the subcontractor a reasonable opportunity to read them; otherwise a clause can be annulled (Article 6:233(b) DCC and Article 6:234 DCC).

That protection does not apply to a party that, at the time of contracting, is a legal entity within the meaning of Article 2:360 DCC that last published its annual accounts (or for which the group exemption of Article 2:403(1) DCC was last applied), or that has 50 or more people working for it, or whose filing with the Trade Register shows this (Article 6:235(1) DCC), or that itself repeatedly uses the same or nearly the same general terms (Article 6:235(3)). And between businesses that are not both established in the Netherlands, the Civil Code rules on general terms do not apply at all, whatever law governs the contract; what counts is the establishment that is to perform under the contract (Article 6:247(2) and (3) DCC).

Passing on main contract obligations one-to-one remains risky, because the relationship between client and main contractor differs from that between main contractor and subcontractor.

Essential Points of Attention for Subcontracting Under Dutch Law

The order of priority of contract documents requires explicit attention in subcontracts. Schedules and deadlines from the main contract must be translated into realistic deadlines for each subcontractor, taking dependencies into account. Pay-when-paid clauses, under which the main contractor only pays after it has been paid by the client, occur in practice. Title 7.12 DCC does not regulate them, so their effect depends on the wording and on general contract law.

Extra work deserves particular attention, since subcontractors are often not authorised to agree changes directly with the client. Procedures on extra work and changes in standard terms, such as §§ 35 and 36 of the UAV 2012 (versie 2025), should therefore be passed on in adapted form. Dispute resolution must be aligned as well: § 49 UAV 2012 (versie 2025) provides for arbitration under the arbitration rules of the Raad van Arbitrage voor de Bouw. A subcontract with a different dispute clause can lead to separate proceedings about the same defect. Include the relevant main contract provisions in the subcontract in adapted form, rather than a general reference to terms the subcontractor may not know.

What General Conditions Apply in Dutch Construction Law?

Dutch construction contracts often incorporate standard terms: the UAV 2012 for the execution of works designed by the client, the UAV-GC for integrated contracts and the DNR (De Nieuwe Regeling) for architects, engineers and consultants. They regulate responsibilities, risks, payment and dispute resolution, but only apply if the contract makes them applicable.

A contract is formed by an offer and its acceptance (Article 6:217 DCC). A party that has accepted general terms is bound by them, even if the user understood or should have understood at the time of contracting that the other party did not know their content (Article 6:232 DCC). A clause can, however, be annulled if it is unreasonably onerous or if the other party had no reasonable opportunity to read the terms (Article 6:233 DCC), subject to the exceptions in Articles 6:235 and 6:247(2) DCC described above. Contractors and large clients often use their own general terms alongside standard terms.

UAV Conditions for Executive Works in the Netherlands

The Uniform Administrative Conditions (UAV) 2012 regulate the execution of works where the design is provided by the client. The current version, the UAV 2012 (versie 2025), was adopted by the Minister for Housing and Spatial Planning on 17 February 2025 and published in the Government Gazette (Staatscourant 2025, 6896). It deletes § 12(1)-(3) on the contractor’s liability after completion; according to the explanatory note, § 12(1) and (2) conflicted with Article 7:758(4) DCC as amended by the Wkb. The UAV is divided into numbered paragraphs (§): for example, §§ 35 and 36 deal with extra and reduced work and changes to the specifications.

The UAV-GC (Uniform Administrative Conditions for Integrated Contracts) is intended for design and build and other integrated contracts, in which the contractor is responsible for both design and execution. The UAV-GC 2025 succeeds the UAV-GC 2005. Always check which version your contract refers to.

DNR and International Contract Forms Under Dutch Law

The DNR (De Nieuwe Regeling) contains standard terms for the relationship between clients and architects, engineers and other consultants, including provisions on the use of designs and on liability for design errors. Check which version your contract incorporates.

International projects sometimes use FIDIC contract forms (Red Book, Yellow Book, Silver Book) or NEC contracts. If Dutch law governs the contract, mandatory Dutch rules still apply alongside these forms. For example, a contractor’s liability for known hidden defects that it concealed cannot be excluded or limited (Article 7:762 DCC).

How Do You Prevent Battle of Forms Situations in the Netherlands?

A battle of forms arises when offer and acceptance refer to different general terms. Under Article 6:225(3) DCC, the second reference has no effect unless it also expressly rejects the general terms referred to first. If it does not, the terms referred to first apply.

Large clients and contractors regularly refer to their own general terms in tender requests and offers. This leads to uncertainty about which terms apply. Timing and an express rejection are therefore decisive.

Legal Operation of Condition Battles Under Dutch Law

Example: a client places an order (an offer) that refers to its own general terms. The contractor accepts, but refers to the UAV 2012 or its own terms and does not expressly reject the client’s terms. Under Article 6:225(3) DCC, the client’s terms then apply. If the contractor states in its acceptance that its own terms apply and that the client’s terms are not accepted, the second reference does have effect. The acceptance then deviates from the offer and in principle counts as a new offer and a rejection of the original one (Article 6:225(1) DCC); the contractor’s terms apply if the client accepts that new offer. Which message counts as the offer and which as the acceptance follows from the general rules on contract formation (Article 6:217 DCC).

Strategic Contract Formation and Clause Testing in the Netherlands

Effective contract formation requires clear communication about the applicable terms. Agree explicitly during negotiations which terms apply, and record this in the signed contract. The user must also give the other party a reasonable opportunity to read its terms: by handing them over before or at the conclusion of the contract, by making them available electronically before or at that time in a way that allows them to be stored, or, if that is not reasonably possible, by announcing before the contract is concluded where they can be inspected or have been filed, or where they can be consulted electronically, and that they will be sent on request (Article 6:234(1) and (2) DCC). If the terms were not handed over or made available electronically before or at the conclusion of the contract, the clauses are also voidable if the user does not promptly send the terms at its own expense when the other party asks for them (Article 6:234(1) and (2)). If the contract is not concluded electronically, providing the terms electronically requires the other party’s express consent (Article 6:234(3)).

A clause in general terms is voidable if it is unreasonably onerous for the other party (Article 6:233(a) DCC). The black and grey lists of Articles 6:236 and 6:237 DCC only apply to contracts with consumers. If Dutch law governs the contract, a clause can also be set aside if applying it would be unacceptable by standards of reasonableness and fairness (Article 6:248(2) DCC); this also applies where Article 6:247(2) excludes the rules on general terms.

Standard terms such as the UAV and UAV-GC are not law; they only apply by agreement. For cost increases after the contract was concluded, Article 7:753 DCC contains a specific rule (see below).

Who Bears the Risk of Price Increases in a Dutch Construction Contract?

If no price was agreed, or only an estimate (richtprijs), the client owes a reasonable price (Article 7:752(1) DCC). If costs rise after the contract was concluded because of circumstances that cannot be attributed to the contractor, the court can, at the contractor’s request, adjust the agreed price, provided the contractor did not have to take the risk of such circumstances into account when setting the price (Article 7:753(1) DCC).

Construction projects often have long lead times, during which prices of materials and labour can change considerably. An agreed estimate may not be exceeded by more than 10%, unless the contractor warned the client as early as possible that a larger overrun was likely, so that the client could still limit or simplify the work (Article 7:752(2) DCC). The same applies if the price depends on the estimated duration of the work (Article 7:752(3)).

How Does Price Adjustment Work Under Article 7:753 DCC?

Under Article 7:753(1) DCC, the court can adjust the agreed price in whole or in part to the cost increase. The contractor may adjust the price itself, without a court, if the increase results from incorrect information supplied by the client that was relevant for setting the price, unless the contractor should have discovered the error before the price was set (Article 7:753(2)). Both options only apply if the contractor warned the client as soon as possible of the need for a price increase, so that the client can either terminate the contract (Article 7:764 DCC) or propose to limit or simplify the work (Article 7:753(3)).

Many contracts regulate price risk themselves, for example through indexation clauses or sector risk arrangements; these only apply if the contract incorporates them. Under § 47 UAV 2012 (versie 2025), the contractor is entitled to additional payment for cost-increasing circumstances that it did not need to take into account, that cannot be attributed to it and that increase the cost of the work considerably. The contractor must notify the client in writing as soon as possible, after which the parties consult; instead of agreeing to compensation, the client may limit, simplify or terminate the work.

How Does the Building Quality Assurance Act Influence Construction Contracts in the Netherlands?

Since 1 January 2024, the Quality Assurance for Building Act (Wkb) has amended Title 7.12 DCC for building works. The contractor must give its warnings in writing and unambiguously (Article 7:754(2)), must hand over a completion file (Article 7:757a) and is liable for defects not discovered at completion, unless they cannot be attributed to it (Article 7:758(4)); these last two rules only apply to contracts concluded on or after 1 January 2024 (Article 218(1) Transitional Act for the new Civil Code). The Wkb also amended public building law, originally the Housing Act (Woningwet), to introduce a new system of quality assurance.

The Wkb aims to improve the quality of buildings. Contracting parties must take the new responsibilities and liabilities into account in their contracts.

Extension of Liability After Delivery Under Dutch Law

The general rule is that the contractor is released from liability for defects that the client should reasonably have discovered at completion (oplevering) (Article 7:758(3) DCC). For building works, Article 7:758(4) DCC departs from this: the contractor is liable for defects not discovered at completion, unless they cannot be attributed to it. This cannot be departed from to the detriment of a consumer client; in other cases, only if the contract expressly says so. Article 7:758(4) only applies to contracts concluded on or after 1 January 2024 (Article 218(1) Transitional Act).

The client must protest within a reasonable time after it discovered, or should reasonably have discovered, a defect (Article 6:89 DCC), and must in principle give the contractor the opportunity to remedy the defect within a reasonable period (Article 7:759(1) DCC). A claim for a defect becomes time-barred two years after the client protested; if the client set the contractor a period to remedy the defect, those two years only start at the end of that period, or earlier if the contractor indicated that it would not repair the defect, and the period is extended while the contractor investigates or attempts to repair the defect (Article 7:761(1) and (3) DCC); for building works, it is in any event time-barred twenty years after completion, and for other works ten years (Article 7:761(1) and (2) DCC).

Warning Obligation and Quality Declarations in the Netherlands

The contractor must warn the client of errors in the assignment that it knew or should reasonably have known, and of defects in materials, the site and the plans, drawings, calculations and specifications provided by the client (Article 7:754(1) DCC). For building works, the warning must be given in writing and unambiguously, and the contractor must point out the possible consequences for proper performance in good time; this cannot be departed from to the detriment of a consumer client (Article 7:754(2)). For example, a contractor must warn if it knows or should know that architect drawings supplied by the client contain errors.

For contracts concluded on or after 1 January 2024 (Article 218(1) Transitional Act), when the contractor reports that a building is ready for completion, it must hand over a file that gives full insight into its performance of the contract and in any event contains drawings and calculations of the building and its installations, a description of the materials and installations used and of the building’s use functions, and the information needed for use and maintenance (Article 7:757a DCC). The contract should also state who arranges and pays for the quality assurance required under public building law.

Adaptation of UAV Conditions to Wkb in Dutch Law

The UAV 2012 (versie 2025) brings the UAV in line with the Wkb by deleting § 12(1)-(3). According to the explanatory note in the Government Gazette, a working group of representatives of clients and contractors under an independent chair did not reach agreement on a new text. Under the UAV 2012 (versie 2025), liability after completion therefore follows Article 7:758 DCC, unless the contract expressly provides otherwise (which is not possible against a consumer client).

Under § 12(4) UAV 2012 (versie 2025), a claim for a defect for which the contractor is liable by law can no longer be brought after five years from completion, or after ten years if the work has collapsed or threatens to collapse, or has become or threatens to become unfit for its intended purpose, and this can only be remedied or prevented at very high cost. If the specifications prescribe a maintenance period, these periods run from the day after that maintenance period ends (§ 12(5)). Check whether your contract uses the UAV-GC 2025 or other terms instead.

What Role Does Procurement Play in Construction Contracts Under Dutch Law?

Public authorities (aanbestedende diensten), such as the State, provinces, municipalities and water authorities, must apply the procurement procedures of the Procurement Act 2012 (Aanbestedingswet 2012) to works contracts with an estimated value at or above the EU threshold (Article 2.1 Procurement Act 2012, which refers to the threshold in Directive 2014/24/EU). Procedures include the open and restricted procedure, the competitive dialogue and the innovation partnership.

The Procurement Act 2012 implements the European procurement directives in Dutch law. A contracting authority must treat businesses equally and without discrimination (Article 1.8). For example, a municipality that has a school built with an estimated value above the threshold must follow a European procurement procedure.

Procurement Procedures and Award Criteria in the Netherlands

In an open procedure, any interested business can submit a tender; the time limit for tenders is at least 45 days from the date the contract notice was sent (Article 2.71(1) Procurement Act 2012). In a restricted procedure, only selected candidates may tender: the time limit for requests to participate is at least 30 days, and for tenders at least 40 days from the invitation to tender (Article 2.71(2) and (4)). Shorter periods are possible in specified cases, for example after a prior information notice (Article 2.71(5)).

The contract is awarded to the most economically advantageous tender. As a rule, this is determined on the basis of the best price-quality ratio; the authority may instead use lowest cost or lowest price, but must then give reasons in the tender documents (Article 2.114 Procurement Act 2012).

Legal Challenges and Dispute Resolution in Dutch Procurement Law

Before concluding the contract, the authority must observe a standstill period of at least 20 calendar days, starting on the day after the award decision was sent to the tenderers and candidates concerned (Article 2.127 Procurement Act 2012); the law provides some exceptions. A tenderer that disagrees with the award decision should therefore act within that period, usually by starting summary proceedings (kort geding) before the civil court.

What Are Important Points of Attention for International Construction Contracts in the Netherlands?

International construction projects in the Netherlands sometimes use international contract forms such as FIDIC or NEC, combined with a choice of Dutch law. If Dutch law applies, the mandatory rules of Title 7.12 DCC apply alongside the contract form. Disputes can be referred to arbitration, for example under the rules of the ICC or the Netherlands Arbitration Institute (NAI).

FIDIC (Fédération Internationale des Ingénieurs-Conseils) publishes standard contract forms for different allocations of design and execution risk. The FIDIC Red Book is intended for projects where the client supplies the design, while the FIDIC Yellow Book is intended for design and build.

FIDIC and NEC Contract Structures Under Dutch Law

The FIDIC Silver Book is intended for turnkey projects in which the contractor bears complete responsibility for design, execution and delivery. NEC (New Engineering Contract) is a British family of contracts based on cooperation, in which the parties jointly manage project risks, for example through early warnings of potential problems.

Arbitration and International Cooperation in the Netherlands

The Netherlands Arbitration Institute (NAI) administers arbitrations under its own rules; see our article on the 2024 NAI Arbitration Rules. The ICC International Court of Arbitration administers arbitrations worldwide. A foreign arbitral award to which a recognition and enforcement treaty applies, such as the 1958 New York Convention, can be recognised and enforced in the Netherlands (Article 1075 Dutch Code of Civil Procedure); likewise, awards made in the Netherlands can be enforced in the other states party to that Convention.

English is frequently used as the language of international arbitration, and Dutch lawyers can advise and act in English. The costs of arbitration depend on the institute, the amount in dispute and the number of arbitrators; check the cost rules of the institute before you agree on an arbitration clause.

How Do You Resolve Construction Disputes Effectively in the Netherlands?

Construction disputes usually concern extra work, delays, defects or payment. Many Dutch construction contracts provide for mediation, binding advice or arbitration, for example before the Raad van Arbitrage in bouwgeschillen (RvA). Without such a clause, the ordinary Dutch courts have jurisdiction.

Under § 49 UAV 2012 (versie 2025), disputes between client and contractor are settled by arbitration under the arbitration rules of the Raad van Arbitrage voor de Bouw, and the parties expressly waive their right to go to the ordinary courts. This only applies if the UAV forms part of the contract. Specialised arbitrators can handle technical discussions efficiently.

Dispute Prevention and Escalation Under Dutch Law

Prevent disputes by recording progress, delays and changes during execution, for example in regular construction meetings, and by warning and objecting in writing in good time. For additions or changes requested by the client, the contractor can only claim a higher price if it pointed out in time that the price would increase, unless the client should have understood this itself (Article 7:755 DCC). Warnings under Article 7:754 DCC are often decisive later as well.

Mediation can be a useful first step: an independent mediator helps the parties negotiate a settlement but cannot impose a decision.

Arbitration Procedures and Cost Management in the Netherlands

The Raad van Arbitrage in bouwgeschillen handles construction disputes with specialised arbitrators. An arbitration clause in standard terms, such as § 49 UAV 2012 (versie 2025), only applies if those terms form part of the contract.

The costs of arbitration, legal assistance and experts depend on the amount at stake and the complexity of the dispute; the arbitral tribunal decides on the costs under the applicable arbitration rules. To enforce an arbitral award in the Netherlands, leave for enforcement (exequatur) is required from the provisional relief judge of the district court in whose district the place of arbitration is located (Article 1062(1) Dutch Code of Civil Procedure).

Frequently asked questions about construction contracts in the Netherlands

What is a design and build contract under Dutch law?

In a design and build (D&B) contract, one contractor designs and builds the work. The construction part is a contract for work under Article 7:750 DCC. Unlike in the traditional model, the contractor is responsible for its own design: the rule that errors in client-supplied designs are for the client’s account (Article 7:760(3) DCC) does not cover a design made by the contractor. Parties often use the UAV-GC standard terms.

Is there a Construction Contracts Act in the Netherlands?

No separate act exists. Construction contracts are governed by Title 7.12 of the Dutch Civil Code (Articles 7:750-7:769 DCC), which the Quality Assurance for Building Act (Wkb) amended with effect from 1 January 2024. Standard terms such as the UAV 2012 and UAV-GC are not law; they only apply if the contract incorporates them.

Can the client terminate if the work will not be finished on time?

If, even before the agreed completion date, it becomes likely that the work will not be completed on time or properly, the court can dissolve the contract in whole or in part at the client’s request (Article 7:756(1) DCC). The client can also terminate the contract in whole or in part at any time, but must then pay the price for the whole work minus the savings resulting for the contractor, against delivery of the work already completed; if the price depended on the contractor’s actual costs, the amount due is based on the costs incurred, the work done and the profit the contractor would have made on the whole work (Article 7:764 DCC).

What price is due if only an estimate (richtprijs) was agreed?

If no price was set, or only an estimate, the client owes a reasonable price, taking into account the contractor’s usual prices and the expectations it raised (Article 7:752(1) DCC). An estimate may not be exceeded by more than 10%, unless the contractor warned the client in good time that a larger overrun was likely (Article 7:752(2)).

May a Dutch contractor use subcontractors?

Yes. The contractor may have the work carried out by others under its direction, and for parts of the work may also leave the direction to others, but it remains liable for proper performance of the contract (Article 7:751 DCC). The contract may restrict the use of subcontractors.
