Construction Mediation: What Actually Happens?

3 November 2025 · infraADR

For someone who has never participated in a mediation, the process can seem somewhat opaque.

Who needs to attend? What does the mediator actually do? Do the parties spend the day sitting across a table from each other? And what happens if no agreement is reached?

While every mediation is different, understanding the process can help parties prepare for it more effectively.

What is construction mediation?

Mediation is a confidential, facilitated dispute resolution process in which an independent mediator assists the parties to identify the issues in dispute, consider their respective positions and explore whether an agreed resolution can be reached.

Importantly, the mediator does not determine the outcome. Unlike a judge or arbitrator, the mediator does not decide which party should succeed. The parties retain control over whether they reach agreement and, if they do, the terms of that agreement.

For construction and infrastructure disputes, this distinction can be particularly important. The issues may involve complex contractual, technical and commercial considerations, while the parties may also have an ongoing project or business relationship to manage.

A structured process, tailored to the dispute

Mediation is not simply a meeting between the parties on the appointed day.

AMDRAS-accredited mediators operate within Australia's national framework for mediator training, accreditation and professional practice. The framework establishes recognised standards for the conduct of mediation, while allowing the mediator to tailor the process to the particular circumstances of the dispute.

At infraADR, that means applying an established mediation framework while considering the nature and complexity of the dispute, the parties involved, the contractual and commercial context, and the issues that need to be addressed.

A relatively discrete payment or valuation dispute may require a different approach from a complex infrastructure dispute involving multiple claims, technical experts and significant ongoing project interfaces. The process should reflect those differences.

The intake process

An important part of the mediation occurs before the mediation day itself.

The mediator will ordinarily conduct an intake or preliminary session with the parties. This assists the mediator to understand the nature of the dispute, identify the participants and issues, consider whether mediation is appropriate and determine how the process should be structured.

It also provides an opportunity to address practical matters such as who should participate, whether those attending have appropriate authority to negotiate, what information may need to be available and whether there are particular matters that should be addressed before the mediation.

For complex construction and infrastructure disputes, this preparation can be particularly valuable. It allows the mediator to understand the broad context of the dispute without prejudging its merits and helps ensure that, when the parties come together, the mediation is focused on the issues that genuinely need to be resolved.

Who participates?

The appropriate participants will depend on the dispute.

Typically, each party will be represented by people who understand the issues and have sufficient authority to negotiate. Lawyers, technical advisers and experts may also participate where their involvement will assist the process.

Having the right people involved is important. Construction disputes can involve legal rights, technical questions, commercial considerations and project consequences simultaneously. Effective mediation requires the people involved to be able to understand and evaluate those different dimensions when considering potential outcomes.

What happens during the mediation?

While mediation follows an established professional framework, the way the mediation is conducted can be adapted to the particular dispute and the needs of the parties.

The process may involve joint discussions between the parties as well as confidential private sessions between the mediator and each party.

During those discussions, the mediator may assist the parties to clarify the matters genuinely in dispute, explore their respective interests and priorities, consider the strengths and risks associated with their positions, and examine possible pathways to resolution.

The mediator manages the process, but the parties remain responsible for the outcome.

In construction and infrastructure matters, the mediator's understanding of the industry can also be valuable. Familiarity with the commercial and project environment means less time needs to be spent explaining how projects operate and more attention can be directed to the issues separating the parties.

What if the dispute settles?

If the parties reach agreement, the terms of the settlement are documented and agreed between them.

One of the advantages of mediation is that the parties retain control over the outcome. Rather than having a decision imposed on them, they can negotiate a resolution that reflects the commercial realities of the dispute and, where relevant, what is needed to allow the project to move forward.

This can be particularly valuable in construction and infrastructure, where resolving the immediate dispute is often only part of the objective. The parties may also need to restore a workable relationship and continue delivering the project together.

Importantly, the parties have the opportunity to develop a clear and workable written agreement that records how the dispute will be resolved. This provides certainty about what has been agreed and allows both parties to move forward on that basis.

For parties who may have spent considerable time and resources dealing with a dispute, that finality can be one of the most valuable outcomes of mediation. Once the agreed issues have been resolved and documented, the parties can put the dispute behind them and redirect their attention to the project and their respective businesses, rather than allowing the disagreement to continue consuming management time and affecting the commercial relationship.

And if it doesn't settle?

Not every mediation results in settlement.

If agreement is not reached, the parties retain the rights available to them under their contract and at law, subject to the arrangements governing the mediation.

That does not necessarily mean the mediation has been unsuccessful. The process may narrow the issues genuinely in dispute, improve each party's understanding of the other's position, identify matters requiring further information or consideration, and provide a foundation for subsequent negotiations or proceedings.

Why is mediation particularly relevant to construction?

Construction disputes occur within projects, not in isolation from them.

While a dispute is being addressed, works may still need to progress, decisions still need to be made and the parties may need to continue working together for months or years.

A well-structured mediation provides an opportunity to consider the legal, technical and commercial dimensions of the dispute while retaining focus on a fundamental question: is there a commercially sensible way to resolve this dispute?
