Construction Dispute Boards in Nigeria (2026): DRB/DAB, When to Use, How to Draft Clauses and Are Decisions Enforceable?

The use of dispute boards is becoming a standard practice on major construction projects in Nigeria, to address disputes before they disrupt the works. They are particularly useful on long-term and technically complex projects, where waiting for litigation or arbitration can result in significant delay and increased costs.

The Arbitration and Mediation Act 2023 has modernised Nigeria’s arbitration framework, while major infrastructure, energy, roads and port projects continue to attract significant investment. Against this background, parties to construction contracts need to consider not only how disputes will ultimately be resolved, but also how they can be addressed while a project is still underway.

A dispute board can provide that early intervention. Depending on the contractual arrangement, the board may assist the parties in avoiding disputes altogether or issue decisions on disputes that arise during the works. The parties can then preserve arbitration as the final means of resolving matters that remain contested.

This article considers when a dispute board is appropriate for a Nigerian project, how the relevant contractual provisions should be drafted, and the extent to which board decisions can be enforced in Nigeria.

Should a Nigerian project  Have a Dispute board?

For a long-term or technically complex project, a dispute board can be a useful part of the contract’s dispute resolution framework. It is particularly suited to projects involving multiple technical interfaces, substantial expenditure and a significant risk of delay.

A dispute board may be appropriate where:

• Duration and complexity. The works run for years and involve significant technical interfaces, power, oil and gas, ports, highways, water.
• Early intervention matters. You want issues resolved during execution to protect the programme, not after completion.
• Technical expertise is decisive. Disputes turn on engineering judgment that a board of experts can assess quickly.
• Budget allows a retainer. The parties can absorb ongoing member fees and periodic site visits, modest against the cost of delay.
• Lenders require continuity. Financiers want a mechanism that keeps the project moving and provides a clear route to enforceable outcomes.

The appropriate structure will depend on the project and the parties’ requirements. A dispute board does not necessarily replace arbitration. In many construction contracts, the two mechanisms can operate together: the board addresses disputes during the project, while arbitration provides a final forum for matters that remain unresolved.

The key, therefore, is not simply to include a dispute board clause, but to draft the clause carefully. The contract should make clear what the board can decide, when its jurisdiction arises, the effect of its decisions, and how unresolved disputes may proceed to arbitration or another agreed forum.

What Is a Dispute Board (DRB/DAB) and How Does It Work?

A dispute board is a panel, usually comprising one or three independent and suitably qualified members, appointed at or near the beginning of a construction contract to help the parties prevent and resolve disputes during the project.

Unlike arbitration or litigation, which generally arise after a dispute has occurred, a dispute board can be involved throughout the project. Depending on the applicable rules and contract, the board may receive project information, attend site visits, assist the parties with emerging disagreements and issue a formal determination when a dispute is referred to it. The FIDIC suite of contracts and the ICC Dispute Board Rules provide established frameworks for the appointment and operation of dispute boards.

The terminology varies between contracts and rules. A Dispute Review Board (DRB) generally issues recommendations, although the contractual effect of those recommendations depends on the applicable rules. A Dispute Adjudication Board (DAB) generally issues decisions that are binding on the parties in accordance with the contract, subject to any agreed right to challenge the decision through arbitration or another dispute resolution process.

The 2017 FIDIC suite uses the term Dispute Avoidance/Adjudication Board (DAAB), reflecting the board’s role both in helping the parties avoid disputes and in deciding disputes referred to it.

For Nigerian projects, therefore, the label used for the board is only part of the analysis. The contract should clearly state the board’s powers, the matters it may determine, the procedure for making a referral, the effect of its recommendation or decision, and the parties’ rights following an unsuccessful challenge.

Standing vs Ad Hoc Dispute Boards

A standing board is appointed at contract signature and remains in place for the life of the project, conducting regular site visits and staying familiar with progress. This is best for long-duration infrastructure works, where the board’s accumulated knowledge speeds decisions and its presence deters posturing. An ad hoc board is convened only when a dispute arises. It is cheaper for shorter or lower-value contracts but loses the preventive value of a standing panel, members must be briefed from scratch, and the deterrent effect is absent. For most major Nigerian infrastructure projects, a standing board delivers better value.

Typical Powers, Composition and Role During the Project Lifecycle

A dispute board’s powers flow entirely from the contract. Typically the board is empowered to: conduct site visits at agreed intervals; receive progress reports and correspondence; give informal advice on emerging disagreements; and issue reasoned decisions on disputes formally referred to it. Members must be independent and free of conflicts, and are usually chosen for a blend of engineering, contractual and legal expertise. On a three-member board, each party typically nominates one member and the two nominees agree the chair.

Across the project lifecycle, the board moves from a preventive advisory role in the early and middle phases to a determinative role when a formal referral is made, issuing a decision within a defined window, commonly 84 days from referral under the FIDIC forms.

Construction Dispute Boards vs Adjudication vs Arbitration: Side-by-Side Comparison

Dispute boards, adjudication and arbitration serve different purposes in construction disputes. The key differences are in timing, cost, the effect of the decision and the extent to which the process provides finality.

Reading the comparison

The main advantage of a dispute board is its involvement while the project is ongoing. It allows issues to be addressed before they develop into larger claims or cause significant delay. This comes at the cost of maintaining the board throughout the project, but that cost may be justified on large or complex projects.

On binding effect and enforceability, the contract and applicable rules are critical. A board’s decision does not have the same status as an arbitral award simply because it is described as binding. The contract should therefore clearly state the effect of the board’s decision and the procedure for referring an unresolved dispute to arbitration.

Adjudication can provide a faster determination of a specific dispute, while arbitration generally offers greater finality. The appropriate mechanism will depend on the nature of the project, the parties’ priorities and the terms of the contract.

Decision Framework, Which Mechanism Should Be Used?

• Dispute Board: Suitable for long-term or technically complex projects where the parties need continuous involvement and early resolution of disputes.
• Adjudication: Suitable where a quick determination is required on a specific issue, such as payment or an extension of time.
• Arbitration: Suitable where the parties require a final determination of a dispute and an enforceable arbitral award.

For major projects, the mechanisms do not necessarily have to be alternatives. A contract may use a dispute board to address issues during construction, while retaining arbitration as the final dispute resolution mechanism.

Are Dispute Board Decisions Binding and How Are They Enforced in Nigeria?

A dispute board decision derives its effect primarily from the contract and the rules incorporated into it. Nigeria does not currently have a dedicated statutory regime governing the enforcement of dispute board decisions. This makes the drafting of the dispute resolution clause particularly important.

The contract should state clearly whether a board’s decision is immediately binding, when it becomes final, the period within which a party may challenge it, and what happens if a party fails to comply.

Under FIDIC-based arrangements, for example, a DAB or DAAB decision may be binding on the parties and subject to implementation even where a party has given notice of dissatisfaction. If no notice is given within the prescribed period, the decision becomes final and binding.

How to make DB decisions binding and enforceable

The clause should address at least three issues:

• Binding effect: State expressly whether the decision is immediately binding and whether the parties must comply pending any arbitration.
• Challenge period: Specify the period within which a party may give notice of dissatisfaction or otherwise challenge the decision. Under FIDIC forms, 28 days is commonly used.
• Non-compliance: Provide a clear mechanism for dealing with a party’s failure to comply, including referral of the failure to arbitration where appropriate.

For example:

“The Board’s decision shall be binding on the Parties and shall be given effect unless and until revised by agreement or arbitral award. A Party dissatisfied with the decision may give notice of dissatisfaction within 28 days of receiving it. Where no such notice is given, the decision shall become final and binding. A failure to comply with a final decision may be referred directly to arbitration.”

The wording should, however, be adapted to the applicable dispute board rules and the governing law of the contract. A clause should not assume that a board decision has the same enforcement status as an arbitral award. Under Nigerian law, the statutory recognition and enforcement framework applies to arbitral awards, which is one reason for providing a clear route from an unresolved board decision to arbitration.

Enforcement Routes in Nigeria

Where a party fails to comply with a binding dispute board decision, the available remedy will depend on the terms of the contract and the nature of the decision.

• Contractual enforcement: A party may bring a claim based on the contractual obligation to comply with the board’s decision, including a claim for payment where appropriate.
• Injunctive relief: Where the decision requires a party to take or refrain from taking a particular action, the appropriate court remedy may include an injunction, subject to the usual requirements.
• Arbitration: Where the contract provides for arbitration, non-compliance or the underlying dispute may be referred to arbitration. An arbitral award can then be enforced under the Arbitration and Mediation Act 2023.
• Interim measures: Where necessary, a party may seek interim relief from a court with the requisite jurisdiction to preserve the position pending arbitration or other final resolution.

The party seeking enforcement should retain the contract and dispute board clause, the referral and correspondence, the board’s decision, evidence of the board’s appointment and jurisdiction, and proof of non-compliance. These documents will be important in establishing that the board acted within the authority given to it by the parties.

Risks and limits

A board decision may be challenged where, for example, the board exceeded its contractual jurisdiction or failed to follow a procedure required by the contract. The absence of clear provisions dealing with the binding effect of the decision and the consequences of non-compliance can also create uncertainty.

The dispute board clause should therefore address these issues from the outset.

How to Draft an Effective Dispute Board Clause for Nigeria

A dispute board clause should clearly address the board’s composition, powers, procedure and the effect of its decisions. It should also provide a clear route for challenging a decision and, where appropriate, referring the matter to arbitration.

Essential Clause Elements

A well-drafted clause should address:

• Scope: Specify which disputes may be referred to the board.
• Composition: State whether the board will have one or three members and whether it will be standing or ad hoc.
• Appointment: Set out the appointment process, qualifications, independence requirements and a fallback mechanism if an appointment cannot be agreed.
• Procedure: Address site visits, meetings, referrals, submissions and the procedure for issuing decisions.
• Decision: State the time within which a decision must be issued and whether it must be reasoned.
• Binding effect: Clearly state whether the decision is immediately binding, when it becomes final, and the period for giving notice of dissatisfaction.
• Costs: Provide for members’ fees, expenses and the allocation of costs between the parties.
• Arbitration: State how an unresolved dispute or failure to comply with a board decision may be referred to arbitration.
• Other matters: Where relevant, address confidentiality, immunity or liability of board members and applicable exclusions.

Sample Wording

The following is illustrative and should be adapted to the applicable contract and dispute board rules:

“The Board shall issue its reasoned decision within 84 days of a referral, unless the Parties agree otherwise. The decision shall be binding on the Parties, who shall give effect to it unless and until it is revised by agreement or arbitral award. A Party dissatisfied with the decision may give notice of dissatisfaction within 28 days of receiving it. Where no notice is given within that period, the decision shall become final and binding.”

The clause should also provide for what happens if a party fails to comply with a binding decision. For example:

“Where a Party fails to comply with a binding decision, the other Party may refer the failure to arbitration. The tribunal may give effect to the Board’s decision by appropriate award, subject to the terms of this Agreement and applicable law.”

The precise wording should be aligned with the dispute board rules incorporated into the contract, particularly where FIDIC or ICC rules are being used.

Operational best practice, setting up and operating a dispute board in Nigeria

Good drafting is necessary but not sufficient. A dispute board only delivers value if it is properly constituted and disciplined in operation.

Selection and appointment process

Appoint the board early, ideally at contract signature for a standing board. Vet members for independence, relevant technical and contractual expertise, and availability. Use the contract’s fallback appointing authority (such as a professional institution) to resolve any deadlock over the chair. Document each member’s declaration of independence at the outset and refresh it periodically.

Meetings, record-keeping and documents

Hold regular site visits and meetings on a fixed schedule, with a standing agenda covering progress, emerging issues and any referrals. Keep a complete, indexed record of all correspondence, progress reports, minutes and decisions. This record is not administrative housekeeping, it is the evidential foundation for any later enforcement, so store it securely and maintain a single source of truth accessible to counsel and the project manager.

Managing costs, retainers and evidence-handling

Agree a transparent retainer plus meeting-fee model up front, with clear cost allocation in the clause. Handle evidence consistently: exchange documents on a defined timetable, mark confidential materials, and preserve originals for any dispute that escalates to arbitration.

Practical enforcement playbook, step by step

When a party receives an adverse decision, or when the other side ignores a favourable one, move deliberately through these steps.

1. Check the clause and time limits. Confirm whether the decision has become final, and whether any notice of dissatisfaction window has expired.
2. Issue a formal notice to comply. Put the defaulting party on written notice, specifying the decision and the compliance deadline.
3. Convert to an arbitral award. Where the clause allows, refer non-compliance to arbitration and seek an award giving effect to the decision, the route to enforceability under the Arbitration and Mediation Act 2023 and the New York Convention.
4. Seek court enforcement or a declaration. Enforce as a contractual debt, or apply for a declaration and injunctive relief in the Federal High Court or the relevant State High Court, subject to jurisdiction.
5. Prepare for challenge. If enforcement is resisted, marshal evidence of the board’s appointment, jurisdiction and the procedure followed to defeat any procedural irregularity argument.

Template timeline and documents to file

Keep ready: the contract and dispute board clause; the referral and any notices; the reasoned decision; declarations of the board’s appointment and independence; the meeting and site-visit record; and evidence of default. A tight, chronological bundle shortens enforcement and strengthens your position against jurisdictional challenge.

Roles, counsel, project manager, lender’s counsel

Counsel drives the enforcement strategy and any arbitration conversion; the project manager supplies the factual and technical record and witnesses; and the lender’s counsel monitors compliance and, where the clause allows, directs referral to arbitration to protect the security package.

Sample clause annex and drafting checklist

For project teams, a practical annex is invaluable: a set of model clauses, a FIDIC-style DAB clause, a “final unless referred” binding clause, an automatic conversion clause, and lender-protection wording, together with a printable drafting checklist. Treat any model wording as a starting point to be tailored to the specific contract and reviewed by counsel before use. Verbatim model clauses should be sourced from, and attributed to, the official FIDIC and ICC materials.

Conclusion and Recommended Next Steps

For most major Nigerian projects in 2026, a dispute board can provide an effective means of addressing disputes while the works are ongoing, particularly where the project is long-term or technically complex. Adjudication may be appropriate where a quick determination is required on a specific issue, while arbitration remains an important option where the parties require a final and enforceable determination.

The effectiveness of a dispute board depends significantly on the contract. The clause should clearly address the board’s composition and powers, the effect of its decisions, the period for challenging them and the procedure for dealing with non-compliance or referring the matter to arbitration.

Parties undertaking major projects should therefore review their existing dispute resolution clauses and consider whether a standing board, adjudication procedure, arbitration, or a combination of these mechanisms is appropriate for the project.
