Sometimes—but there is no worldwide rule requiring mediation before every construction lawsuit, adjudication or arbitration. Whether you must mediate depends on the jurisdiction, the type and stage of the dispute, and the exact wording of your contract’s dispute-resolution clause.
A requirement can come from a statute or court rule, from a clause the parties agreed to, or from a later voluntary agreement. Those are different obligations. A required pre-action meeting may allow mediation as one format without making mediation itself compulsory.

What “mandatory construction mediation” can mean
Before deciding that mediation is compulsory, identify the source of the alleged obligation. The same word—“mandatory”—is used for three different situations, with different consequences if a party does not participate.
1. A statute or court rule requires it
A legislature or court rule may require mediation for a defined class of cases. Such a rule normally specifies which claims are covered, when mediation occurs, how a mediator is appointed, where it takes place and what exclusions apply. It does not automatically extend to every construction dispute in the country.

2. The contract requires it
Parties can agree to mediate before commencing litigation, arbitration or adjudication. The clause may prescribe a sequence such as notice, negotiation, mediation and then a formal proceeding. It may also set a notice method, a time period, a named appointing body or a requirement that representatives attend with settlement authority. The clause must be read as written, including definitions and exceptions.
3. The parties choose it voluntarily
Even when no statute or contract clause compels mediation, both sides can agree to use it. They may do so before a claim is filed or while court, arbitration or adjudication proceedings are already under way. A voluntary submission is not evidence that mediation was a precondition to bringing the original claim.
| Source of obligation | What makes it binding | Questions to check |
|---|---|---|
| Statute or court rule | The enacted provision or procedural rule applies to the particular claim and stage. | Is this claim within the defined class? Are there exclusions, filing steps or an order requirement? |
| Contract clause | The parties agreed to the wording, usually when signing the construction contract. | What must happen first, who gives notice, which deadlines and escalation steps apply, and what event permits a formal case? |
| Voluntary agreement | Both parties consent to mediate, sometimes after a dispute has begun. | What terms govern this mediation, and does it run alongside another proceeding? |
A reliable way to determine whether you must mediate
- Identify the forum and governing law. Locate the court, tribunal or arbitral seat that would handle the dispute and the law governing the contract. Construction projects involving several locations can raise more than one potentially relevant regime.
- Classify the dispute. A payment claim, construction-defect action, trust claim, professional-negligence claim, enforcement application and request for urgent relief may be treated differently.
- Mark the procedural stage. Determine whether the matter is still at the notice stage, already in litigation, in arbitration, in adjudication or seeking enforcement of an existing decision. A rule that applies before a claim is issued may not apply to an enforcement application.
- Read the entire dispute clause. Check definitions, notice addresses, negotiation periods, mediation wording, appointment mechanics, cost provisions, escalation order and the clause that permits a party to commence a formal proceeding.
- Check the current official rule. Use the live statute, court rule or protocol rather than an old contract guide or a summary written for another jurisdiction. Confirm amendments and any forms or procedural directions.
- Record the consequences, not assumptions. Verify whether the rule requires an application, a court order, a stay, attendance by a person with authority to settle or a particular mediator. Do not assume that a missed step automatically defeats a claim; that consequence depends on the governing law and wording.
How selected jurisdictions handle construction mediation
The examples below illustrate different mechanisms. They are not a universal survey and cannot determine the law governing a particular project.
England and Wales: a required pre-action process is not automatically mandatory mediation
The Pre-Action Protocol for Construction and Engineering Disputes applies to construction and engineering disputes, including professional-negligence claims involving construction professionals. It sets out pre-action steps and identifies exceptions. The parties’ meeting may take the form of mediation, but the protocol does not make mediation the required format in every construction case.

The distinction matters. A party may have to exchange information, set out its position and attend a meeting under the protocol, while still being able to use a different format for that meeting. The Practice Direction – Pre-Action Conduct and Protocols says a court will expect compliance with an applicable protocol or with the direction if the dispute proceeds to litigation.
The construction protocol lists exceptions including proceedings to enforce an adjudicator’s decision, claims for interim injunctive relief, summary-judgment cases and disputes recently addressed by adjudication or another formal alternative-dispute-resolution process. These exceptions are procedural boundaries, not a general statement that mediation is optional in every circumstance. Check the live protocol and its application to the claim before relying on an exception.
Ontario: Rule 24.1 expressly covers specified actions
Ontario’s Rule 24.1 of the Rules of Civil Procedure is titled “Mandatory Mediation.” It applies to specified actions, including actions under the Construction Act, while excluding trust claims. The rule also contains scope, location, timing and procedural requirements.
That wording does not make mediation mandatory for every construction dispute in Canada. A case must fall within the rule’s covered actions, and the rule’s exclusions and procedures must be followed. A construction claim outside the specified class, a trust claim, or a matter in another Canadian jurisdiction cannot be classified by importing Rule 24.1.

Texas: a court-order route for qualifying construction-defect suits
Texas Civil Practice and Remedies Code §27.0041 addresses construction-defect suits seeking more than $7,500 in damages. Under the provision, a claimant or contractor may file a motion to compel mediation within the statutory period. Once a qualifying motion is made, the court is directed to order mediation subject to the statute’s terms.
The section also addresses when mediation must begin, how a mediator is appointed if the parties cannot agree, participation and equal cost contribution, subject to the statutory agreement provision. This is a defined procedure in qualifying litigation—not a blanket requirement that every Texas construction dispute be mediated before suit.

Philippines: CIAC rules support both contract-based and voluntary mediation
The Construction Industry Arbitration Commission’s CIAC Mediation Rules (Resolution No. 11-2005) provide a model clause that parties may include for referring future disputes to CIAC mediation. If incorporated into a contract, that clause can create an agreed step that the parties must analyze according to its wording.
The same rules also apply when a construction dispute has no mediation clause but both parties wish to submit it. They may choose mediation to try to avoid arbitration or litigation, or while those proceedings are in progress. The rule therefore illustrates the difference between an obligation created at contract formation and a later voluntary submission; it does not establish that all Philippine construction disputes must be mediated first.

New Zealand: adjudication rights and mediation can coexist
Part 3 of New Zealand’s Construction Contracts Act 2002 gives a party to a construction contract a right to refer disputes to adjudication, subject to stated exceptions. The legislation also says that nothing in that part prevents the parties from submitting a dispute to another procedure, such as mediation, whether concurrently with adjudication or not.
This structure shows that a statutory right to adjudication is not the same as a mediation precondition. The parties may mediate alongside adjudication, but the Act’s adjudication provisions and any contract terms still need to be checked for the particular dispute.
Mediation, adjudication, arbitration and a pre-action meeting are different
| Process | Who starts it | What the third party does | How it relates to mediation |
|---|---|---|---|
| Mediation | A rule, contract clause or agreement may require or permit it. | A mediator facilitates negotiation; the parties decide whether to settle. | It does not become adjudication or arbitration merely because a dispute is already filed. |
| Adjudication | Often available under a statute or contract, subject to its scope and exceptions. | An adjudicator determines the dispute under the applicable procedure. | Some regimes permit mediation at the same time, and a protocol may exclude disputes already handled by adjudication from certain pre-action steps. |
| Arbitration | Usually founded on an arbitration agreement or applicable rule. | An arbitrator determines the dispute under the arbitration procedure. | A mediation clause may require a mediation attempt before arbitration, but the two processes remain legally distinct. |
| Pre-action meeting | A protocol or court direction may require the parties to meet before litigation. | The parties exchange positions and explore resolution; the format may vary. | In England and Wales, the construction protocol says the meeting may take the form of mediation. That does not make mediation the mandatory format in every case. |
What to inspect in a construction contract’s dispute clause
Sequence and trigger
Look for language such as “shall,” “must,” “condition precedent,” “before commencing proceedings” or “as a prerequisite.” Then identify the event that starts the sequence: a notice of dispute, a payment rejection, a defect notice or another defined trigger. A clause may require negotiation first and mediation only if negotiation fails.
Notice and appointment mechanics
Check the permitted delivery method, the address for notices, the information the notice must contain and the method for selecting a mediator. Some clauses name an institution; others require the parties to agree and provide a fallback appointment method. A clause that simply says “the parties shall mediate” may leave practical details to a later agreement or to an applicable institutional rule.

Who must attend
Determine whether attendance is required by a project representative, a lawyer, an insurer or a person with authority to settle. A mediation can be ineffective if the contract or rule requires meaningful participation but the attending representative cannot make or obtain a settlement decision.
Timing, costs and confidentiality
Read any stated time limits, cost-sharing language and confidentiality provisions together with the governing law. These jurisdictions do not support one universal rule on deadlines, privilege, sanctions, fees or enforceability. Those consequences must be verified for the specific contract and forum rather than assumed from a clause used on another project.
Escalation and the next forum
Identify what happens if mediation ends without agreement. The clause may permit arbitration, adjudication or court proceedings, sometimes in a prescribed order. It may also allow urgent relief to be sought without completing every step. Do not infer that a failed mediation waives a claim or extends a limitation period; obtain jurisdiction-specific advice on those issues.
If mediation is required, prepare for the actual process
- Confirm the obligation in writing. Save the applicable statute, rule, protocol and contract clause, and note the claim category and procedural stage that bring them into play.
- Send the correct notice. Use the contract’s notice method and include the information it requires. If a court rule supplies a form or filing step, follow that rule rather than a generic mediation invitation.
- Agree or obtain the mediator. Apply the appointment mechanism in the clause or rule. If the parties cannot agree and the governing provision supplies a fallback appointment, use that route.
- Bring a representative with settlement authority. Confirm in advance who can approve terms and how any required insurer, owner, contractor or public-body approval will be obtained.
- Prepare a focused position. Organize the contract, change orders, payment records, programme evidence, defect reports, photographs and the remedy sought. Separate facts that are agreed from issues that require a decision.
- Check costs and confidentiality before exchanging material. Establish who pays the mediator and venue, how costs are shared and what the applicable rule says about the use of mediation communications.
- Protect parallel procedural rights. Record every filing, notice and contractual deadline that applies to the dispute. Mediation does not automatically replace adjudication, arbitration or court requirements unless the governing terms say so.
- Document the outcome. If the parties settle, reduce the agreement to a signed document that identifies the obligations, dates, releases and any required approvals. If they do not settle, record the next permitted procedural step without assuming that mediation itself decides the dispute.
When an exception or different route may matter
Urgent interim relief, enforcement of an adjudicator’s decision, summary judgment and a dispute recently dealt with through adjudication or another formal ADR process can be treated differently under the England and Wales construction protocol. Other jurisdictions may have their own exclusions. The fact that a case feels urgent does not by itself establish an exception; the applicable rule must be checked.
A statutory right to adjudicate can also operate alongside mediation. New Zealand’s legislation expressly preserves that possibility, and the Philippine CIAC rules contemplate mediation during arbitration or litigation when the parties choose it. The correct question is therefore not simply “Should we mediate?” but “What process is available or required at this stage, and can mediation run with it?”
What if mediation does not settle the dispute?
Mediation produces no imposed decision. If the parties do not reach an agreement, the dispute normally continues through whatever forum the statute, contract or court rules permit: litigation, arbitration or adjudication. The exact next step, any notice requirement and the effect on filing or limitation periods are jurisdiction-specific.

Quick Recap
Practical answer for a project team
- Do not describe mediation as mandatory without naming the jurisdiction, claim type, procedural stage and legal or contractual source.
- Separate a required pre-action meeting from a requirement to use mediation as that meeting’s format.
- Distinguish a statute that automatically covers a defined case from a statute that lets a party ask the court to order mediation.
- Read the dispute clause in full, including notice, sequence, appointment, attendance, costs, confidentiality, exceptions and the next forum.
- Check the current official rule before relying on an exclusion, deadline or consequence.
- Get advice specific to the project before treating a missed mediation step as a bar, waiver, stay or extension of time.
