Mandatory Mediation in South Africa (2026): a Practical Guide for Construction Contracts (FIDIC, JBCC, NEC)

Mandatory mediation in South Africa became a procedural reality for civil litigants in the Gauteng Division of the High Court when the Directive on Mediation took effect on 22 April 2025, requiring parties to engage a mediator and file a mediator’s report before any trial date can be allocated. For contractors, project owners and in-house counsel managing disputes under FIDIC, JBCC or NEC contracts, the implications are immediate: construction dispute mediation is no longer an optional “nice-to-have” but a compulsory procedural step that can determine whether a matter even reaches a courtroom. This guide delivers the contract redlines, compliance checklists and tactical decision frameworks that construction professionals need to align existing dispute-resolution clauses with the new landscape.

What Mandatory Mediation Means for Construction Projects in South Africa

The core compliance question for every project team is straightforward: can our matter proceed to trial without a completed mediation? Under the Gauteng mediation directive, the answer is no, and industry observers expect similar directives to expand to other divisions in the near term. Here is what construction stakeholders must do right now.

• Who is affected. All parties to civil trial matters in the Gauteng Division, including construction claims under standard-form contracts, must comply. The directive applies to matters in both the Johannesburg and Pretoria seats of the Gauteng Division.
• Immediate action: check your contract. Review every active and pipeline construction contract for its dispute-resolution clause. If the clause does not include a mandatory mediation step with clear timelines, mediator-appointment mechanics and a mediator-report obligation, it must be amended or supplemented by a side agreement.
• Schedule mediation early. Mediation must be completed, and the mediator’s report filed, before the court will allocate a trial date. Delays in initiating mediation translate directly into delays in obtaining a hearing date.
• Preserve adjudication and arbitration rights. Mediation before litigation does not extinguish contractual rights to adjudication or arbitration. Best-practice drafting preserves these parallel mechanisms while satisfying court requirements.

The decision flow is simple: (1) identify whether the dispute falls within the Gauteng Division’s jurisdiction; (2) engage a mediator through a recognised mediation organisation or by agreement; (3) complete mediation in good faith; (4) file the mediator’s report with the court; and (5) only then apply for a trial date. Failure at any step risks the matter being struck from the roll.

Legal and Regulatory Background: The Gauteng Mediation Directive and National Signals

South Africa’s shift toward compulsory mediation did not begin in 2025. Mandatory mediation has been part of labour law for three decades under the Labour Relations Act 66 of 1995, and the courts have long encouraged voluntary mediation through practice notes and the broader evolution of mediation globally. What changed in 2025 was the introduction of a binding procedural instrument for civil litigation.

The Gauteng Directive on Mediation (22 April 2025)

The Directive on Mediation in the Gauteng Division, issued on 22 April 2025, establishes mediation as a compulsory procedural step for specified civil trial matters. Its key provisions include:

• Pre-trial mediation requirement. Parties must meaningfully engage in mediation before a trial date will be allocated. The directive frames this as a “progressive policy choice” drawing support from South Africa’s constitutional commitment to access to justice and the proven efficiency of mediation in labour disputes.
• Mediator’s report. A mediator’s report must be filed with the court confirming that mediation took place and recording the outcome, whether full settlement, partial settlement or impasse. Without this report, no trial date is issued.
• Recognised mediation pathways. Parties may refer the dispute to any recognised mediation organisation, or they may agree on a private mediator. The directive does not prescribe a single body, giving parties flexibility to choose mediators with sector-specific expertise, a critical point for construction law disputes where technical knowledge matters.
• Effective date. The directive took effect on 22 April 2025 and applies to all civil matters in the Gauteng Division from that date forward.

National and Procedural Developments (2025–2026)

The Gauteng directive is not an isolated event. The South African Judiciary’s media statement accompanying the directive explicitly noted that mandatory mediation has been part of South African law for three decades in the labour sphere and that extending it to civil matters is a natural progression. Industry observers expect other divisions of the High Court to adopt similar directives as the Gauteng pilot demonstrates results in reducing case backlogs, with some matters reportedly having trial dates scheduled as far out as 2031 before the directive’s introduction.

Internationally, comparable mandatory mediation frameworks for construction disputes have gained momentum. Early indications suggest that the South African approach will continue to evolve, with practice directives and protocols likely to be refined as courts gather data on compliance rates and settlement outcomes. For construction professionals, the practical effect is that mediation compliance in South Africa is now an operational necessity, not merely a contractual option.

How Mandatory Mediation Intersects with Construction Dispute Pathways

Construction contracts in South Africa typically provide a tiered dispute-resolution mechanism, negotiation, then adjudication or a dispute board, and finally arbitration. The Gauteng mediation directive introduces a court-directed mediation layer that sits alongside (and sometimes overlaps with) these contractual mechanisms. Understanding when and how to deploy each tool is essential for effective construction dispute mediation.

Timeline and Urgency: When Mediation Must Occur

Under the Gauteng directive, mediation must be completed before any trial date is allocated. For construction disputes that are headed to court rather than arbitration, this means mediation is triggered at the litigation-commencement stage, after pleadings close but before the matter is set down for trial. Where a contract provides for arbitration as the final-tier mechanism (as most FIDIC and NEC contracts do), the court-directed mediation requirement applies only if a party instead initiates High Court proceedings.

The practical implication: if your contract’s dispute clause channels disputes to arbitration, you avoid the court-imposed mediation requirement, but you may still benefit from including a contractual mediation step before arbitration to reduce costs and preserve commercial relationships.

Enforceability and Interplay: Preserving Parallel Rights

A mediated settlement reduced to writing and signed by the parties is contractually binding and enforceable under ordinary contract-law principles. Courts will enforce such agreements. However, mediation itself is non-binding, if the parties do not reach settlement, they retain full rights to proceed to adjudication, arbitration or trial (as applicable under their contract).

The key drafting takeaway: mandatory mediation in South Africa does not replace adjudication or arbitration. It adds a compulsory early step that, if properly managed, can resolve or narrow disputes before significant legal costs are incurred.

Contract Drafting: Model Mandatory Mediation Clauses and Redlines for FIDIC, JBCC and NEC

Standard-form construction contracts used in South Africa were drafted before the Gauteng directive. While each suite includes some form of dispute-resolution procedure, none explicitly addresses the court-imposed mediation report requirements. The redlines below show how to bring each contract into alignment with mandatory mediation in South Africa.

FIDIC Mediation Clause, Model Redline and Commentary

Under the FIDIC 2017 Yellow and Red Books, disputes proceed through the Dispute Avoidance/Adjudication Board (DAAB) and then to arbitration under ICC Rules. There is no standalone mediation step. To incorporate a FIDIC mediation clause that satisfies the Gauteng directive, insert the following as a new Sub-Clause (e.g., Sub-Clause 21.7) or as a Particular Condition:

“Prior to referring any Dispute to arbitration under Sub-Clause 21.6, the Parties shall first attempt to resolve the Dispute by mediation. The mediation shall be conducted by a mediator agreed by the Parties or, failing agreement within 14 days of a written request for mediation, appointed by [insert recognised mediation organisation]. The mediation shall be completed within 60 days of the mediator’s appointment. The mediator shall produce a written report recording the outcome of the mediation. Mediation does not suspend or alter any time limits applicable to the DAAB process or arbitration.”

• Do: Specify a fallback appointing body (e.g., AFSA, SAICE, or another recognised mediation organisation) to prevent tactical delays in mediator selection.
• Do: Include a “without prejudice” confidentiality carve-out confirming that mediation communications cannot be used in subsequent arbitration or court proceedings.
• Don’t: Make mediation a condition precedent to adjudication under the DAAB, adjudication must remain available as a rapid interim mechanism during the project.
• Don’t: Set mediation timelines so long that they interfere with contractual limitation periods for referring disputes to the DAAB.

JBCC Mediation, Model Redline and Commentary

The JBCC Series 2000 and subsequent editions (including the JBCC 6.2) provide for disputes to be referred to adjudication and then arbitration. JBCC mediation provisions, where they exist, are typically optional. To comply with the Gauteng directive, amend Clause 40 (Dispute Resolution) or add a supplementary clause:

“40.X Mediation: Before any Dispute is referred to litigation in the High Court, the Parties shall submit the Dispute to mediation conducted by a mediator appointed by agreement or, failing agreement within 14 days, nominated by [recognised mediation organisation]. The mediation shall be completed within 45 days of the mediator’s appointment. The mediator shall prepare a report for filing with the court in accordance with applicable practice directives. This clause does not preclude a Party from referring a Dispute to adjudication under Clause 40.1 at any time.”

• Do: Make clear that mediation applies only to disputes headed to court (not to those proceeding directly to JBCC adjudication or contractual arbitration).
• Do: Align the mediator-report obligation with the content requirements expected by the Gauteng Division.
• Don’t: Remove or weaken adjudication rights, JBCC adjudication remains the primary rapid-resolution mechanism during construction.

NEC Dispute Resolution, Model Redline and Commentary

NEC4 contracts (and NEC3 predecessors) use Option W1 or W2 for dispute resolution, proceeding through a senior representative negotiation, adjudication by the Adjudicator, and then tribunal (arbitration or litigation as selected in the Contract Data). NEC dispute resolution does not include a mandatory mediation step. Insert the following as a Z-clause or Contract Data amendment:

“Z[X], Mandatory Mediation: If the tribunal selected in the Contract Data is litigation, the Parties shall attempt to resolve any dispute by mediation before issuing proceedings. The mediation is conducted by a mediator agreed by the Parties or appointed by [recognised mediation organisation] within 14 days of a written request. The mediation is completed within 42 days. The Mediator issues a written report recording the outcome. Mediation does not affect any time period for referral to or decision by the Adjudicator.”

• Do: Link the mediation trigger to the tribunal pathway, if arbitration is selected, court-directed mediation does not apply, but contractual mediation may still be desirable.
• Do: Preserve the NEC’s strict adjudication timelines. The Adjudicator’s role and four-week decision period must not be affected.
• Don’t: Use vague language such as “the Parties may consider mediation”, the Gauteng directive requires meaningful engagement, not discretionary consideration.

Practical Drafting Notes for All Contract Suites

• Mediator appointment timeline: Specify 14 days for agreement, with automatic referral to a recognised organisation if the parties cannot agree. This prevents one party from obstructing the process.
• Mediation completion deadline: 42–60 days from appointment is realistic for construction disputes, balancing urgency with the need to prepare technical submissions.
• Mediator report format: The report should, at minimum, record the parties’ names, the date and duration of the mediation, whether settlement (full or partial) was reached, and, if not, that the mediator certifies good-faith participation. The report is filed with the court as part of the mediation report requirements under the Gauteng directive.
• Confidentiality carve-out: All mediation communications remain without prejudice and may not be disclosed in subsequent proceedings, except as required by the mediator’s report filed with the court, which should contain only procedural information, not substantive admissions.
• Costs allocation: State that mediation costs are shared equally unless the parties agree otherwise, or as a court may later direct in costs orders.

Operational Compliance: Running a Mediation That Satisfies Courts

Inserting the right clause is only the first step. Construction professionals must also execute the mediation process in a way that meets the court’s expectations. The Gauteng directive and supporting protocol require meaningful engagement, not a box-ticking exercise. Courts have indicated that mediation is a compulsory procedural step, and failure to comply can result in matters being struck from the roll.

Pre-Mediation Checklist

Before the mediation session, the project team should prepare the following:

• Summary of the dispute: A concise written summary (no more than 10 pages) identifying the issues, the relief sought, and the commercial context. Include a project timeline and key correspondence.
• Supporting documents: Relevant contract extracts, variation orders, payment certificates, delay notices, engineer’s decisions and any adjudicator’s determinations already issued.
• Attendance with authority: Ensure that the person attending the mediation has full authority to settle. Courts and mediators will scrutinise whether decision-makers actually participated. Sending a junior representative without settlement authority undermines the process and may be treated as non-compliance.
• Mediator selection: Confirm the mediator’s appointment in writing. Where construction disputes are involved, choose a mediator with relevant industry experience, ideally someone familiar with the contract suite (FIDIC, JBCC or NEC) and the technical subject matter.
• Logistics: Book a neutral venue, confirm the date and duration (allow at least one full day for complex construction matters), and agree on the mediation protocol (opening statements, joint sessions, caucuses).

The Mediation Session: Agenda, Authority and Settlement

A well-structured mediation session for construction disputes typically follows this sequence:

1. Opening statements: Each party presents its case to the mediator and the other side (15–30 minutes per party).
2. Joint discussion: The mediator facilitates a dialogue to identify common ground and narrow issues.
3. Private caucuses: The mediator meets separately with each party to explore settlement positions, test assumptions and develop options.
4. Negotiation and offers: The mediator shuttles between the parties, conveying offers and counter-offers.
5. Settlement or impasse: If the parties reach agreement, a written settlement agreement is drafted and signed at the session. If not, the mediator confirms the impasse and proceeds to prepare the mediator’s report.

Key practice point: if partial settlement is achieved (for example, agreement on a variation valuation but not on a delay claim), record the settled items separately and continue with the unsettled items to trial or arbitration.

Mediator’s Report: Required Content, Format and Court Filing

The mediator’s report is the document that unlocks access to a trial date under the Gauteng directive. Its mediation report requirements include the following minimum content:

• Parties’ names and case reference number.
• Date(s) and duration of the mediation session(s).
• Confirmation that all parties attended and participated in good faith (or, where applicable, that a party failed to attend or participate meaningfully).
• Outcome: Whether the dispute was settled in full, settled in part, or remains unresolved.
• Mediator’s certification that the mediation was conducted in accordance with the applicable protocol.

The report must not disclose the substance of any settlement offers, concessions or admissions made during the mediation. It is a procedural certificate, not a record of negotiations. The report is filed with the Registrar of the Gauteng Division, together with the application for a trial date.

Risks of Non-Compliance and Practical Mitigations for Contractors

The consequences of ignoring mandatory mediation in South Africa are tangible and immediate. Courts have signalled that non-compliance will be met with real procedural sanctions, not merely judicial disapproval.

Court Sanctions and Costs Consequences

• Striking from the roll: A matter may be struck from the court roll if the parties have not complied with the mediation directive. This means losing an allocated trial date, which, given current backlogs, could result in delays of months or years before a new date is obtained.
• Adverse costs orders: A party that unreasonably refuses to participate in mediation or obstructs the process risks an adverse costs order, even if that party ultimately succeeds on the merits at trial.
• Reputational risk: In the close-knit South African construction industry, a reputation for obstructing dispute resolution can damage commercial relationships and affect future tendering prospects.

Practical Mitigations

• If mediation is genuinely inappropriate (for example, in urgent interdict applications or matters involving fraud), apply to the court for a dispensation with written reasons before the trial-allocation stage. Do not simply ignore the directive and hope the court will overlook non-compliance.
• Where the other party refuses to mediate, document your own good-faith attempts to initiate and schedule mediation. File this correspondence with the court alongside an application explaining the other party’s non-compliance. The court is likely to view the compliant party favourably.
• Build mediation into project budgets and programmes. The cost of mediation (mediator fees, venue hire, legal representation) is modest compared to the cost of trial, and the time saved can be significant. Industry observers expect that mediation compliance in South Africa will become as routine as pre-trial conferences within a few years.
