Step‑by‑step Procedure to Refer a Construction Dispute to a Dispute Adjudication Board (DAB) in Mauritius

The dispute adjudication board procedure in Mauritius provides contractors, employers and project owners with a structured, contract-based mechanism to resolve construction disputes without waiting for full-scale arbitration. DABs are embedded in most FIDIC-based contracts used on Mauritian infrastructure and building projects, and they produce binding interim decisions that keep projects moving while preserving each party’s right to a final determination. With the Construction Industry Authority (CIA) rolling out updated contractor grading schedules and procurement guidance during 2026, parties who understand the referral steps, notice periods and enforcement routes hold a significant tactical advantage. This guide sets out every stage of the adjudication process in Mauritius, from the first contemporaneous notice through to post-decision enforcement and the preservation of arbitration rights.

Overview of the DAB Process and Who It Applies To

A Dispute Adjudication Board is a standing or ad hoc panel, typically one or three members, appointed under the construction contract to hear disputes that have not been resolved through the contract’s internal claim machinery. The concept is well established internationally through FIDIC standard forms and ICC Dispute Board Rules, and it occupies a deliberate middle ground: faster and less formal than arbitration, yet more authoritative than negotiation or mediation. In Mauritius, DABs appear most frequently in contracts based on FIDIC Red Book (Conditions of Contract for Construction), Yellow Book (Conditions of Contract for Plant and Design-Build) and their locally adapted variants used in public-sector procurement.

The DAB’s core function is to issue a decision that is binding on both parties immediately, meaning work continues, payments are made and programme adjustments are implemented even while a dissatisfied party retains the right to refer the matter onward to arbitration. This “comply now, argue later” principle protects cash flow and programme certainty, two issues that dominate Mauritian construction disputes. Either party to the contract may refer a dispute; it is not limited to the contractor.

Quick Definitions

Understanding the core terminology is essential before engaging with the adjudication process in Mauritius. For a broader construction law glossary, see the dedicated resource on this site.

• Dispute Adjudication Board (DAB). A panel of one or three independent professionals appointed under the contract to determine disputes. Distinguished from a Dispute Review Board (DRB), which issues non-binding recommendations.
• Referral Notice (Notice of Adjudication). The formal document by which a party refers a crystallised dispute to the DAB, triggering the procedural timetable.
• Adjudicator. The individual member of the DAB who reviews submissions, conducts hearings and issues the written decision.
• DAB Decision. The written determination, binding on both parties from the date of issue unless and until revised by an arbitral tribunal.

When to Use a DAB in Mauritius

A DAB referral becomes available once a dispute has “crystallised”, that is, one party has made a claim or assertion and the other has rejected it, or the Engineer or Contract Administrator has failed to decide within the contractual time limit. In FIDIC-based contracts, the DAB clause operates as a mandatory pre-condition to arbitration; a party that bypasses the DAB step risks having its arbitration claim declared premature. In Mauritius, this structure is especially common on government-funded and donor-funded projects where FIDIC conditions are specified in procurement documents, and where the CIA oversees contractor registration and grading requirements that may affect a party’s standing to participate in the project, and, by extension, the admissibility of its claim.

Eligibility and Prerequisites for the DAB Referral Procedure in Mauritius

Before a referral can be made, several contractual and practical requirements must be satisfied. Failing to meet them can result in the DAB declining jurisdiction, the responding party challenging admissibility, or, in the worst case, a time bar that extinguishes the claim entirely.

Contract Terms Required

The right to refer a dispute to a DAB must be expressly conferred by the contract. In FIDIC 1999 editions, the relevant provisions appear under Sub-Clause 20.2 (Appointment of the Dispute Adjudication Board) and Sub-Clause 20.4 (Obtaining Dispute Adjudication Board’s Decision). In FIDIC 2017 editions, the equivalent framework is set out under Clause 21. Locally adapted contracts used in Mauritius often modify these sub-clauses, for example, by specifying a sole adjudicator rather than a three-member panel, or by shortening or extending the decision period. The first step for any party contemplating referral is to read the specific DAB clause in the signed contract, including any Particular Conditions and appendices that amend the General Conditions.

Pre-Referral Steps That Preserve Rights

Most FIDIC-based contracts require the claiming party to have served a contemporaneous Notice of Claim within the contractual time limit, commonly 28 days of the event giving rise to the claim (Sub-Clause 20.1 in FIDIC 1999). This notice is a gateway requirement: if it was not served, the DAB or a subsequent tribunal may find the claim time-barred. Beyond the initial notice, the contract typically requires the claimant to submit a fully detailed claim to the Engineer or Contract Administrator, who then has a defined period (often 42 days) to give a determination. Only after that determination is issued, or the time for it has expired without a response, does the dispute crystallise and become referable to the DAB.

Practical preservation steps include maintaining contemporaneous site diaries, photographic records, programme updates and payment records from the date of the event onward. These materials form the evidential backbone of the referral bundle.

Eligibility of Parties, Including Foreign Contractors

Both the employer and the contractor (or subcontractor, where the subcontract contains a DAB clause) may refer a dispute. Foreign contractors working in Mauritius should confirm that their company registration, tax clearance and local representative appointment are current, as the responding party may challenge the referral on the ground that the claimant lacks legal standing or has failed to comply with Mauritius regulatory requirements. Under the 2026 CIA grading updates, contractor classification may also be scrutinised at the admissibility stage, industry observers expect that a mismatch between a contractor’s registered grade and the project class could provide grounds for an objection to the DAB’s jurisdiction.

Step-by-Step DAB Referral Procedure in Mauritius

The following numbered steps trace the typical sequence from the first notice through to enforcement of the DAB decision. Timings are based on standard FIDIC provisions; always check the signed contract for project-specific variations.

Step 1, Serve a Notice of Claim or Notice of Potential Dispute

Serve a prompt written notice to the Engineer or Contract Administrator that identifies the event, the contractual basis for the claim and the relief sought. Under FIDIC 1999 Sub-Clause 20.1, the contractor must give notice within 28 days of becoming aware of (or when it should have become aware of) the event or circumstance giving rise to the claim. Failure to serve this notice within the stipulated period may result in the contractor forfeiting its entitlement entirely, the clause operates as a strict time bar in many FIDIC-based contracts used in Mauritius.

The notice should be concise but specific. It should identify the contract, the relevant clause, the nature of the event (delay, disruption, variation, unforeseen conditions) and a preliminary statement of the relief claimed (time, money or both). Send the notice by the method specified in the contract, typically email with a hard-copy follow-up, and retain proof of delivery with date and time stamps.

Step 2, Refer the Claim to the Contract Administrator or Engineer

After serving the initial notice, the claiming party must submit a fully detailed claim to the Engineer or Contract Administrator within the further period specified in the contract (commonly 42 days from the event under FIDIC 1999). The detailed claim should include a narrative of the facts, a breakdown of the amount claimed, a delay analysis (if time-related) and all supporting documents. The Engineer then has a contractually defined period, typically 42 days, to issue a determination approving, rejecting or modifying the claim.

If the Engineer fails to respond within this period, or if the claimant is dissatisfied with the determination, the dispute is considered to have crystallised and the claimant may proceed to the DAB referral step. Do not skip this stage: where the contract requires it, moving directly to the DAB without first obtaining (or waiting for) the Engineer’s determination may give the responding party a procedural objection.

Step 3, Serve the Notice of Adjudication and Referral to the DAB

The Notice of Adjudication is the formal document that triggers the DAB’s jurisdiction. It must be served on the other party and on each member of the DAB (or, if the DAB has not yet been appointed, on the party with an accompanying request to constitute the panel). The notice should contain the following elements:

• Identification of the contract and parties. Full project name, contract reference and party names.
• Description of the dispute. A clear, bounded statement of the issues to be decided.
• Relief sought. The specific order, declaration or payment amount requested.
• Nominated adjudicator(s). If the DAB is ad hoc, identify the proposed adjudicator and confirm their availability and independence.
• List of annexed evidence. An index of all documents, witness statements and expert reports submitted with the referral.
• Contractual basis. Reference to the DAB clause and any prior notices already served.

Service method should follow the contract. In Mauritius, best practice is to serve by recorded delivery or courier with electronic copy by email, retaining proof of delivery. The notice period for commencing DAB proceedings is contract-dependent; where the contract is silent, the referring party should serve without unreasonable delay once the dispute has crystallised.

Step 4, Appointment and Acceptance of Adjudicator(s)

If the contract provides for a standing DAB, the panel is already in place and this step reduces to confirming availability and absence of conflicts. For ad hoc appointments, the parties typically have 7–14 days to agree on a sole adjudicator or panel. If agreement cannot be reached, most FIDIC contracts designate a nominating authority, often the President of FIDIC, the ICC, or a locally agreed institution, to make the appointment.

Either party may object to a proposed adjudicator on grounds of bias, lack of independence, or insufficient expertise. Objections should be raised promptly and in writing, with reasons. The adjudicator, once appointed, must sign a declaration of independence and disclose any potential conflicts, a requirement that mirrors international best practice as described in the ICC Dispute Board Rules.

Step 5, Exchange of Submissions and Evidence

The adjudicator sets the procedural timetable, which typically involves two rounds of written submissions: the referring party’s statement of case (the “claim bundle”), followed by the responding party’s response, and, if permitted, a reply. Each exchange round usually spans 7–14 days. The adjudicator may request additional information, clarifications or specific documents at any point.

Evidentiary standards in DAB proceedings are less formal than in arbitration or litigation, but the quality and organisation of the evidence remain critical. Contemporaneous records, site diaries, daily labour returns, programme updates and photographs, carry significantly more weight than reconstructed narratives. Parties should present documents in a paginated, indexed bundle with a clear chronological or thematic structure.

Step 6, Adjudicator’s Decision: Compliance and Immediate Effect

The adjudicator must issue a written, reasoned decision within the contractual time limit, typically 28 days from the date of referral. The parties may agree to extend this period if the dispute is complex. The decision is binding on both parties immediately and must be complied with without delay, regardless of whether either party intends to refer the matter to arbitration.

In practice, the decision will direct one or more of the following: payment of a specified sum (with or without interest), an extension of time, a direction to perform or cease a particular action, or a combination. The decision’s binding nature means that the losing party must comply even while reserving its right to challenge the decision in arbitration. Non-compliance is itself a breach of contract, and in Mauritius, the prevailing party may seek enforcement through the courts (see Step 7 below).

Interest on amounts awarded by the DAB typically runs from the date specified in the decision. Parties should check the contract for any agreed interest rate; where the contract is silent, the adjudicator may apply a commercially reasonable rate. The immediate cash-flow effect of a DAB decision is one of its most valuable features, particularly on large infrastructure projects where delayed payments can threaten contractor solvency.

Step 7, Post-Decision: Enforce the DAB Decision and Preserve Arbitration Rights

Once the decision is issued, both parties face parallel obligations: comply with the decision and take the necessary steps to preserve their right to challenge it in arbitration if they are dissatisfied. These two requirements operate independently.

Enforcement. If the losing party fails to comply with the DAB decision, the winning party may seek enforcement through contractual remedies (such as set-off, suspension of work or termination for breach) or through the Mauritius courts. Court enforcement typically involves an application for interim or conservatory relief, the court is asked to order compliance with the binding decision pending the outcome of any arbitration. For guidance on preparing for arbitral proceedings that may follow, see our arbitration hearings preparation guide.

Preserving arbitration rights. A party that wishes to challenge the DAB decision must serve a Notice of Dissatisfaction within the contractual time limit, typically 28 days of receiving the decision under FIDIC Sub-Clause 20.4. Failure to serve this notice in time converts the DAB decision into a final and binding determination from which there is no further recourse. The Notice of Dissatisfaction should identify the aspects of the decision with which the party disagrees and state that the matter is to be referred to arbitration.

Required Documents and Information for a DAB Referral

A well-prepared referral bundle is the single most important factor in achieving a favourable DAB decision. The following table sets out the documents needed for a standard referral under FIDIC-based contracts in Mauritius, together with practical notes on format and authentication.

Practical Evidence Rules and Document Authentication

All exhibits should be assembled in a paginated, indexed bundle with a table of contents. Number each page sequentially and cross-reference documents to the relevant paragraphs of the statement of case. Witness statements should be in the first person, signed by the maker and accompanied by a statement of truth. Expert reports must identify the expert’s qualifications and the instructions under which they were prepared. Where documents originate from outside Mauritius, consider whether notarisation or apostille certification is required, particularly for company registration certificates and powers of attorney. Submitting a disorganised or incomplete bundle is one of the most common reasons for weak DAB outcomes.

Timeline and Key Deadlines for the DAB Procedure in Mauritius

Deadlines in DAB proceedings are contractual, not statutory, the signed contract is the controlling document. The table below sets out common time windows based on standard FIDIC provisions as widely used in Mauritius. Parties must check their own contract for variations.

The critical insight for parties operating in Mauritius is that every one of these deadlines is a potential trap. Missing the 28-day notice window under FIDIC Sub-Clause 20.1, for instance, can extinguish a multi-million-dollar claim. Similarly, failing to serve a Notice of Dissatisfaction within 28 days of the DAB decision converts it into a final determination. Practitioners should maintain a rolling deadline tracker from the first event and update it at each procedural stage. Where the contract interacts with CIA reporting obligations, for example, milestone certifications or grading-related compliance filings, those deadlines should be tracked in parallel to avoid administrative lapses that could affect admissibility.

The typical end-to-end timeline for the DAB procedure in Mauritius, from Notice of Claim to DAB decision, is approximately 10–16 weeks on standard FIDIC terms. Enforcement or arbitration proceedings extend the timeline further, depending on the complexity of the dispute and the court’s docket.

Costs, Fees and Tax Considerations for Adjudication in Mauritius

The cost of adjudication in Mauritius depends on the adjudicator’s fee structure, the complexity of the dispute and whether expert evidence or court enforcement is required. The following table outlines the main cost categories. Parties should obtain specific fee quotes from proposed adjudicators and legal counsel before committing to a referral.

The adjudicator’s fees are typically the largest single cost item. In many FIDIC contracts, the DAB Agreement sets out the adjudicator’s daily rate and provides for reimbursement of travel and subsistence expenses. Parties should factor in the cost of expert evidence, particularly delay analysis, which can be substantial on complex disputes but is often decisive in securing a favourable decision.

What Changes in 2026: CIA Updates and Practical Effects on DAB Referrals

The Construction Industry Authority (CIA) of Mauritius has introduced updated contractor grading schedules and procurement guidance during 2026. While these administrative changes do not alter the DAB procedure itself, they have practical effects on claim admissibility and the documentation required for referral.

The updated grading framework imposes stricter classification criteria for contractors by project value and type. Industry observers expect the likely practical effect to be that a contractor whose grade does not match the project class at the time of the dispute may face admissibility objections, the responding party could argue that the contractor was not properly qualified to undertake the works and therefore lacks standing to claim additional time or money. Early indications suggest that adjudicators are paying closer attention to grading compliance when assessing jurisdiction.

Procurement circulars issued alongside the grading updates also signal tighter requirements for contemporaneous record-keeping and claim substantiation on publicly funded projects. Parties referring disputes to a DAB on these projects should ensure that their referral bundle includes current CIA registration and grading certificates, evidence of compliance with any pre-qualification requirements and confirmation that the contractor’s grade was valid at the relevant project milestones.

Practical checklist for 2026 compliance:

• Confirm the contractor’s current CIA grade before serving the Notice of Adjudication.
• Include a certified copy of the CIA grading certificate in the referral bundle.
• Cross-check the grading certificate against the project class specified in the contract and procurement documents.
• If the contractor’s grade has changed during the project, prepare a brief explanation and supporting evidence showing that the grade was valid at the time of the events giving rise to the claim.

Common Pitfalls and How to Avoid Them

• Missing the notice window. Failure to serve the Notice of Claim within the contractual time limit (commonly 28 days) can extinguish the claim entirely. Mitigation: set up an internal alert system and serve the notice immediately on becoming aware of the event, even if full particulars are not yet available.
• Weak contemporaneous evidence. Relying on reconstructed narratives rather than daily site diaries, photographs and programme updates undermines credibility. Mitigation: mandate daily diary entries signed by the responsible site manager from day one of the project.
• Poorly drafted Notice of Adjudication. A notice that fails to describe the dispute clearly or omits the relief sought may be rejected or lead to a narrow, unhelpful decision. Mitigation: follow the checklist in Step 3 above and have the notice reviewed by construction counsel before service.
• Failure to preserve arbitration rights. Not serving a Notice of Dissatisfaction within the contractual period (typically 28 days) converts the DAB decision into a final binding determination. Mitigation: diarise the deadline immediately on receipt of the decision and serve the notice promptly if dissatisfied.
• Ignoring 2026 CIA grading requirements. Proceeding with a referral without confirming that the contractor’s grade matches the project class risks an admissibility challenge. Mitigation: verify and document grading status before serving the referral.
• Enforcing without preserving arbitration grounds. Seeking court enforcement of a DAB decision without simultaneously serving the Notice of Dissatisfaction can waive the right to challenge the decision later. Mitigation: treat enforcement and preservation of appeal rights as parallel actions, not alternatives.

Conclusion

The dispute adjudication board procedure in Mauritius offers a powerful, contract-based route to resolve construction disputes efficiently while keeping projects on track. The process demands strict compliance with notice periods, a well-organised evidence bundle and careful attention to the 2026 CIA grading requirements that may affect claim admissibility. Parties who follow the step-by-step referral process outlined in this guide, from the initial Notice of Claim through to post-decision enforcement and the preservation of arbitration rights, are best positioned to protect their contractual entitlements and maintain project cash flow. For parties involved in a live dispute or preparing a DAB referral, consulting a qualified Mauritius construction lawyer at the earliest opportunity is strongly recommended.
