Mediation in Construction Disputes: A Practical Guide

Mediation in construction disputes gives owners, general contractors, subcontractors, designers and other project participants a structured way to resolve conflict without asking a judge or arbitrator to decide the outcome. A neutral mediator facilitates negotiations, but the parties retain control over whether they settle and what the settlement terms will be.

For construction executives, mediation is most effective when treated as a business and project-management decision rather than simply another legal proceeding. Contract language, schedule impacts, cost documentation, insurance considerations, project relationships and the authority of the people attending the session can all affect whether mediation produces a workable resolution.

The timing also matters. Construction disputes can remain active long after the original project problem occurs. Arcadis reported that the average North American construction dispute in its 2025 report had a value of $60.1 million and took an average of 12.5 months to resolve, based on 2024 dispute activity. That makes early dispute management particularly consequential for companies managing multiple projects, cash-flow commitments and contractual exposures.

MEDIATION IS A NEGOTIATION PROCESS, NOT A BINDING DECISION

Mediation is a confidential dispute-resolution process in which a neutral third party helps the participants evaluate their positions, identify areas of agreement and negotiate a settlement. The mediator does not generally impose a decision on the parties.

That distinction separates mediation from arbitration and litigation.

For construction disputes, that flexibility can be valuable because the underlying problem is often more complicated than a single dollar figure. A delay claim, for example, may involve schedule responsibility, concurrent delay, acceleration, extended general conditions, liquidated damages, subcontractor impacts and disputed change orders. A negotiated settlement can address several of those issues simultaneously.

CONTRACT LANGUAGE CAN DETERMINE WHEN MEDIATION OCCURS

The first place executives should look when a construction dispute develops is the contract. Dispute-resolution provisions can establish whether mediation is required, when it must occur and which administering organization or procedures govern the process.

For example, the AIA A201-2017 General Conditions provide for mediation of covered claims and disputes as a condition precedent to binding dispute resolution. Under that form, mediation is generally administered by the American Arbitration Association unless the parties agree otherwise. The provision also contemplates mediation proceeding before binding dispute resolution and provides for a 60-day stay of those proceedings from the filing of the mediation request, unless the parties agree to a longer period.

Executives should therefore review:

• The specific contract and incorporated general conditions
• Notice requirements for claims
• Time limits for submitting claims
• Required steps before mediation
• Whether mediation is mandatory or voluntary
• The designated mediation provider
• Venue or locale requirements
• Arbitration or litigation provisions that follow mediation
• Requirements for preserving records, notices and other evidence

Not every construction contract follows the AIA structure. Public contracts, private development agreements, EPC agreements, subcontract forms and negotiated owner-contractor agreements can contain materially different procedures. The contract controls the starting point.

THE BEST TIME TO MEDIATE MAY BE BEFORE THE CLAIM BECOMES EXPENSIVE

Mediation should not automatically be viewed as the final step before a dispute reaches arbitration or litigation. Early mediation can be useful when the parties have enough information to make rational decisions but have not yet invested so heavily in adversarial positions that settlement becomes difficult.

The timing decision should account for the nature of the dispute. A mediation may be premature when the parties do not yet have essential project records, a reliable schedule analysis or sufficient information to evaluate the financial exposure. On the other hand, delaying mediation until after extensive discovery, expert work and substantial legal fees can reduce the economic value of settling.

PREPARATION SHOULD START WITH THE NUMBERS AND THE PROJECT RECORD

A mediation position should be supported by the same project records that management would rely on to make an internal business decision. For contractors and owners, preparation may include:

• Contract documents: the relevant agreement, general conditions, specifications, amendments, change orders, notices and correspondence, organized around the disputed issues
• Schedule evidence: baseline schedules, updates, narratives, critical-path analyses, recovery schedules and contemporaneous project records, which can be central to delay and acceleration disputes
• Cost documentation: the parties should be able to explain how claimed amounts were calculated and connect those amounts to actual project records. Arcadis identified contractor transparency of cost data supporting claimed damages as one of the important factors in early dispute resolution
• Field documentation: daily reports, photographs, meeting minutes, requests for information, submittals, inspection records and correspondence that establish what occurred and when
• Change management records: the history of disputed directives, pricing, approvals, denials and associated schedule effects

A CONSTRUCTION MEDIATOR NEEDS MORE THAN GENERAL ADR EXPERIENCE

The complexity of construction disputes makes subject-matter familiarity an important consideration when selecting a mediator. Construction disputes frequently involve contract interpretation alongside technical issues involving scheduling, estimating, design, engineering, project controls and field operations.

AAA maintains a dedicated construction panel that includes attorneys and industry professionals with construction-related experience. JAMS likewise maintains construction mediators and neutrals with experience handling complex construction matters.

The mediator does not need to be an expert witness for either side. The more useful question is whether the mediator can quickly understand the commercial and technical dimensions of the dispute. Executives should evaluate a mediator’s experience with issues such as:

• Delay and disruption
• Differing site conditions
• Defective work
• Design responsibility
• Payment and change-order disputes
• Insurance and indemnity issues
• Subcontractor claims
• Schedule acceleration
• Cost and damages analysis
• Multiparty disputes

For a straightforward payment dispute, a highly specialized technical background may be unnecessary. For a complex infrastructure dispute involving multiple contractors, design professionals and overlapping delay claims, mediator experience can become much more important.

THE RIGHT PEOPLE MUST BE IN THE ROOM

Authority is one of the most overlooked elements of effective mediation. A project manager may understand every factual detail of a dispute but lack authority to approve a settlement. Conversely, an executive with settlement authority may not understand the project history well enough to evaluate the other side’s position.

The mediation team should therefore combine decision-making authority with technical and contractual knowledge. Depending on the dispute, participants may include a company executive with settlement authority, project management, contract or commercial management, legal counsel, scheduling or damages professionals, risk or insurance personnel, and technical subject-matter experts.

MEDIATION CAN ADDRESS MORE THAN THE AMOUNT OF THE CLAIM

Construction settlements do not have to be limited to a check for disputed damages. The parties may negotiate combinations of financial and operational terms, depending on the dispute and the parties’ authority to make those commitments.

That flexibility is particularly relevant when the parties still have an ongoing business relationship. Consider a contractor and owner involved in a dispute over a delayed project. The dispute may not be solved simply by deciding whether one party owes the other $2 million. Mediation gives the parties room to negotiate that broader business outcome.

COMMON MEDIATION FAILURES ARE OFTEN PREPARATION FAILURES

A mediation can fail even when both parties have legitimate reasons to settle.

One common problem is entering mediation with an opening position that is disconnected from the company’s actual risk. A negotiating position should be informed by the strengths and weaknesses of the contract, evidence, damages analysis and likely alternatives to settlement.

Another problem is treating the mediation statement as a litigation brief. A useful mediation presentation should help the mediator understand the commercial dispute, not simply repeat every allegation in a pleading.

A third problem is failing to identify non-monetary issues. Construction disputes can involve damaged working relationships, disputed responsibility, completion concerns, reputational considerations or disagreements over how a project should be finished. The American Bar Association has specifically noted that construction mediation involves human and organizational considerations in addition to the financial dispute.

EXECUTIVES SHOULD EVALUATE MEDIATION AGAINST THE ALTERNATIVES

Mediation has value only when the expected benefits justify the cost of resolving the dispute through that process. A useful executive assessment compares at least four scenarios.

The correct choice depends on the dispute, contract, jurisdiction and business objectives. A party may have a strong legal position but still conclude that settlement makes more sense because of schedule requirements, continuing project obligations, legal expense or uncertainty. That is not an admission that the claim lacks merit. It is a risk-management decision.

DOCUMENT THE SETTLEMENT AS CAREFULLY AS THE ORIGINAL CLAIM

Reaching a verbal understanding is not the same as completing a settlement. Settlement documents should clearly establish what each party is agreeing to do, the payment obligations, releases, continuing responsibilities, deadlines and treatment of unresolved matters. Depending on the dispute, the settlement may also need to address liens, warranties, insurance issues, confidentiality provisions or obligations involving other project participants.

The precise legal requirements vary by agreement and jurisdiction, so counsel should evaluate the settlement documentation before execution.

The distinction between mediation and settlement is important: mediation is the process, while the settlement is the resulting agreement when the parties successfully resolve the dispute. A well-documented agreement prevents the parties from creating a second dispute over what they believed they resolved in the first one.

MEDIATION WORKS BEST AS PART OF A BROADER DISPUTE STRATEGY

Mediation should be viewed as one component of construction dispute management rather than an isolated event. The strongest dispute-resolution systems start before a formal claim exists. Contract reviews, clear notice procedures, accurate schedules, organized cost records, timely communications and disciplined change management can make later mediation substantially more productive. Arcadis’ recent construction disputes research ranked contract and specification reviews, communication and risk management among the leading claims-avoidance techniques reported for 2024.

That approach also changes the role of senior management. Executives do not need to participate in every project-level disagreement, but they should establish clear escalation points for disputes that could materially affect cash flow, project completion, insurance exposure, customer relationships or future work.

For companies managing large portfolios, consistency matters. A defined escalation process can help project teams identify when a dispute should move from field-level negotiation to executive review, formal claim administration, mediation or another dispute-resolution process.

Construction disputes will remain unavoidable on complex projects. The competitive advantage comes from recognizing which disputes require a formal fight and which can be converted into a negotiated business solution before costs, schedules and relationships deteriorate further.
