Dispute Resolution: Claims, Mediation, and Arbitration

Why Disputes Happen on Construction Projects

Construction projects involve multiple parties, long schedules, incomplete information, and money under pressure. Disagreements over scope, schedule impacts, changed conditions, and payment are common. The question is not whether disputes will arise, but how they will be resolved. Standard contract forms—especially the AIA A201 General Conditions—establish a structured, step-by-step process designed to resolve disputes at the lowest possible level before they reach a courtroom.

The Dispute Resolution Ladder

AIA A201 Article 15 describes a tiered process often called the "dispute resolution ladder." Each rung must generally be attempted before climbing to the next.

Step 1 — Notice and Initial Decision Maker (IDM). When a dispute arises, the party with the claim must give written notice promptly. Under AIA A201, a claim must be initiated by written notice no later than 21 days after the claimant first recognizes the condition giving rise to the claim. Failure to give timely notice can waive the claim entirely. After notice, the Architect typically acts as the Initial Decision Maker. The IDM reviews the claim and issues a written decision within a set period. Either party can accept that decision, or either can reject it and proceed to the next step. The IDM's decision is a prerequisite to moving forward.

Step 2 — Mediation. Before arbitration or litigation, AIA A201 requires the parties to attempt mediation. Mediation is a confidential, non-binding process in which a neutral third party (the mediator) helps the parties reach a voluntary settlement. The mediator does not impose a decision. Under AIA A201, mediation is administered under the Construction Industry Mediation Procedures of the American Arbitration Association (AAA) unless the parties agree otherwise. Either party may demand mediation after the IDM decision. If mediation produces a settlement agreement, both parties sign it and the dispute is closed. If mediation fails, the parties move to the next step.

Step 3 — Arbitration or Litigation. AIA A201 offers two options at this level: binding arbitration (the default in many versions) or litigation in a court of law. Arbitration is administered under the AAA Construction Industry Arbitration Rules. An arbitrator (or panel) hears evidence and issues a binding award that the courts will enforce. Litigation follows standard civil procedure in the applicable jurisdiction. Both are adversarial, expensive, and time-consuming—strong reasons to resolve disputes at earlier steps.

What Makes a Valid Claim

A formal claim is more than a complaint. To be actionable, a written claim must contain three core elements:

1. Entitlement — the legal and contractual basis for the claim. Cite the specific contract clause (for example, AIA A201 Section 15.1 or the Changes clause) that gives the claimant the right to additional compensation or time.

2. Causation / Chronology — a factual narrative, in date order, showing what happened, who was responsible, and how the event caused the impact. Contemporaneous project records—daily reports, RFIs, meeting minutes, correspondence—are the backbone of this section.

3. Quantum — the quantified impact: dollars claimed (with cost breakups: labor, material, equipment, overhead, and profit) and calendar days of schedule extension requested. Unsupported numbers are easily challenged; attach backup documentation.

A claim package typically includes: a cover letter identifying the claim and relief requested, a chronology of events, the entitlement argument with clause citations, and cost and time exhibits.

Documentation: Your Best Defense

Project records created at the time of the event carry far more weight than reconstructed records. Best practices include:

• Daily reports noting weather, manpower, equipment on site, and any unusual conditions
• Photographs with date and location stamps
• Contemporaneous correspondence (emails, letters) that put the other party on notice
• Updated schedules showing the impact of delays
• Cost codes that segregate impacted work from base contract work

Organizing records as events unfold—not after the fact—is the single most effective claims management strategy.

Safety Note

Disputes sometimes escalate tensions on a job site. Supervisors and workers must maintain professional conduct regardless of contractual disagreements. Never allow a contract dispute to distract from site safety. OSHA standards remain in effect throughout any dispute; no contractual disagreement suspends an employer's duty to maintain a safe workplace. If a dispute involves a safety-related directive (for example, a stop-work order over a hazardous condition), comply first and dispute second. Document everything, but never bypass lockout/tagout, fall protection, or other life-safety controls while a claim is pending.

Practical Takeaway for Estimators and Project Managers

Understanding the dispute resolution process before a project begins—not after—is a mark of a professional. Read Article 15 of any AIA contract before signing. Know the notice deadlines. Build record-keeping into your daily workflow. When a potential claim event occurs, give notice immediately, even if you are not sure of the full impact yet. Preserve your rights first; calculate the damages second.
