Construction claims affect nearly every project a general contractor touches. A 2025 CMAA industry survey found that 92% of commercial construction projects exceeding $10 million face at least one formal claim. The average claim on a mid-size project runs $340,000. Understanding how claims work puts you in a stronger position whether you are filing one or defending against one.

This guide breaks down construction claims into their core components. You will learn what triggers a claim, how the process moves forward, and what GCs should do at each stage.

What Makes Something a Construction Claim

A construction claim is a formal demand for something the contract does not currently provide. That demand can be for additional money, more time, or both. The key word is "formal." An informal discussion about a cost increase is not a claim. A written notice citing specific contract provisions and requesting specific relief is.

Claims differ from change orders in one critical way. A change order is a mutual agreement. Both parties accept the scope change and agree on the price and time adjustment. A claim is one-sided. One party asserts a right that the other party has not accepted.

Risk management practices play a direct role in how many issues become formal claims. GCs with documented processes for handling field issues resolve 3 out of 4 potential claims before they reach the formal notice stage.

The Six Main Claim Types

Construction claims group into six categories. Knowing the type helps you understand the evidence requirements.

Delay claims involve time. The contractor argues that an event outside their control pushed the project past its scheduled completion date. Weather delays, owner-directed changes, and design errors are common causes. Proving a delay claim requires a critical path analysis showing that the delay event actually affected the completion date.

Differing site conditions arise when what the contractor finds in the field differs from what the contract documents described. A geotechnical report showing sandy soil when the crew hits solid rock is a classic example. The contractor must prove that the actual conditions materially differ from the contract representation.

Scope changes happen when the owner adds work or modifies existing work. If the parties cannot agree on the cost and time impact, the dispute becomes a claim. Clear scope definitions in the original contract reduce these claims significantly.

Specification defects occur when the design documents contain errors, conflicts, or omissions that cause additional work. Under the Spearin Doctrine, the owner warrants that their plans and specifications are adequate for construction.

Acceleration claims arise when the contractor is forced to compress the schedule. Direct acceleration happens through an explicit order. Constructive acceleration happens when the owner denies a valid time extension but still holds the contractor to the original completion date.

Payment claims involve disputes over amounts owed. Retainage releases, final payment holdbacks, and disputed back-charges all fall into this category. Prompt payment acts in most states set deadlines for payment after proper invoice submission.

How to Respond to a Construction Claim

When a claim lands on your desk, follow a structured response process.

Step 1: Verify the notice. Check whether the claimant followed the contract's notice requirements. Did they provide written notice within the contractual time limit? Did they cite the correct contract provisions? A defective notice does not automatically kill a claim, but it weakens the claimant's position.

Step 2: Review the contract. Pull the relevant contract clauses governing changes, delays, and disputes. Identify the specific provisions the claimant cites and compare their interpretation with yours.

Step 3: Gather your records. Collect daily reports, photographs, meeting minutes, RFIs, and correspondence related to the claim event. Organize them chronologically. The strength of your records determines your negotiating position.

Step 4: Assess liability. Make an honest evaluation. If the claim has merit, early settlement saves money. If it lacks merit, prepare your defense with specific evidence. Partial liability is common. Most claims settle at a negotiated middle ground.

Step 5: Respond in writing. Provide a formal written response within the timeframe your contract specifies. State your position clearly, cite supporting evidence, and propose a resolution path.

What Construction Claims Cost

Claim costs extend far beyond the disputed amount. Understanding total cost helps you decide when to fight and when to settle.

Cost Category	Small Claim (Under $100K)	Mid-Size Claim ($100K-$1M)	Large Claim (Over $1M)
Legal fees	$10,000-$30,000	$50,000-$200,000	$200,000-$1,000,000+
Expert witnesses	$5,000-$15,000	$25,000-$100,000	$100,000-$500,000
Internal staff time	40-80 hours	200-500 hours	1,000+ hours
Resolution timeline	2-6 months	6-18 months	12-36 months
Typical settlement range	40-60% of claimed amount	35-55% of claimed amount	30-50% of claimed amount

The internal staff time cost is often overlooked. Project managers, superintendents, and executives spend hundreds of hours preparing claim documentation, attending meetings, and testifying. That time comes directly off other projects.

Preventing Claims Before They Start

Prevention is where GCs gain the biggest advantage. Every claim you prevent saves $50,000 or more in resolution costs.

Write clear contracts with specific change order procedures. Define notice periods, documentation requirements, and dispute resolution steps. Do not rely on standard form contracts without reviewing them for your specific project.

Hold regular progress meetings with documented minutes. Address issues in writing the week they arise. A problem discussed verbally in week 3 and ignored until week 20 becomes a much harder claim to resolve.

Track subcontractor compliance from day one. Verify insurance, collect lien waivers, and process payments on schedule. SubcontractorAudit automates sub compliance tracking so issues surface before they become claims.

FAQs

What is the difference between a construction claim and a change order? A change order is a mutual agreement between the contractor and owner to modify the contract scope, price, or schedule. A claim is a one-sided demand where the parties disagree. When a change order request is denied and the contractor believes they are entitled to additional compensation or time, the dispute becomes a formal claim.

How long do I have to respond to a construction claim? Response deadlines depend on your contract terms. AIA A201 gives the architect 30 days to make an initial decision on a claim. Most subcontracts allow 14-30 days for the GC to respond. Always check your specific contract. Missing the response deadline can weaken your position.

What is constructive acceleration in construction? Constructive acceleration occurs when the owner denies a legitimate time extension request but still holds the contractor to the original completion date. The contractor is forced to spend additional resources to compress the schedule. This creates a claim for the additional costs of accelerating the work.

Do I need a lawyer for every construction claim? Not necessarily. Small claims under $50,000 are often resolved through direct negotiation between the parties. Claims over $100,000 generally benefit from legal counsel, especially if they involve complex schedule analysis or contract interpretation. Always consult a construction attorney before mediation or arbitration.

What records are most important for defending against a claim? Contemporaneous daily logs, photographs with date stamps, written correspondence, meeting minutes, and schedule updates created at the time of the event carry the most weight. Records prepared after the fact for litigation purposes are less credible. Start documenting on day one of every project.

Can I file a construction claim against a subcontractor? Yes. GCs frequently file claims against subcontractors for delay, defective work, or failure to maintain insurance. The process mirrors claims filed against owners. Provide written notice per the subcontract terms, document the issue, quantify your damages, and follow the dispute resolution procedures in the subcontract.
