Construction claims best practices exist for a reason. When GCs ignore them, the financial consequences are severe. A 2025 Navigant Construction Forum report found that contractors who lack formal claims procedures leave an average of 34% of legitimate claim value on the table. That translates to hundreds of thousands of dollars per project lost to avoidable mistakes.

This analysis covers the most damaging mistakes GCs make when handling construction claims. Each mistake includes the financial impact and a clear fix.

Mistake 1: Missing the Notice Deadline

The contract says written notice within 14 days. The PM thinks verbal communication counts. It does not.

Courts and arbitrators enforce notice provisions strictly. A 2024 study by the American Bar Association's Construction Forum found that 22% of denied construction claims failed solely due to late or missing notice. The claim had merit. The contractor had proof. But the notice arrived outside the contractual window.

The fix. Build notice triggers into your project management workflow. When any event occurs that could become a claim, send written notice within 48 hours. Use a standard template that cites the contract clause, describes the event, and reserves your rights. Even if you do not ultimately file a claim, the notice protects your position.

Mistake 2: Blending Claim Costs With Project Costs

When claim-related work gets coded to general project cost accounts, proving damages becomes nearly impossible.

Opposing counsel will ask one question: "Can you show me exactly which costs relate to this claim event?" If the answer requires sorting through blended accounts, your credibility drops. Arbitrators discount damage calculations that rely on estimates and allocations rather than direct tracking.

The fix. Open separate cost codes within 24 hours of a claim event. Track labor, equipment, materials, and sub costs in dedicated accounts. Even if the claim resolves quickly, having clean cost data strengthens your negotiating position.

Mistake 3: Relying on Memory Instead of Records

The superintendent remembers the conversation clearly. The owner's representative remembers it differently. Without written records, it is your word against theirs.

Construction claims that go to arbitration or litigation are often resolved 18-36 months after the event. Memory fades. Details get confused. Written records created at the time of the event carry far more weight than testimony about what someone remembers.

The fix. Follow up every verbal conversation with a written summary sent by email the same day. State what was discussed, what was agreed, and what remains open. If the other party does not dispute the summary, it becomes part of the project record.

Mistake 4: Skipping the Schedule Analysis

Delay claims without schedule support are guesses. Saying "we were delayed 45 days" means nothing without a critical path analysis showing that the delay event pushed the completion date by 45 days.

Many GCs present delay claims with a narrative explanation but no schedule analysis. This approach fails in formal dispute resolution. Arbitrators and judges want to see the critical path, the float consumed, and the net impact on completion.

Mistake	Frequency Among GCs	Average Claim Value Lost	Cost to Fix
Late or missing notice	22% of denied claims	100% of claim value	$500 (template + process)
Blended cost tracking	45% of negotiated claims	25-40% of claim value	$2,000 (cost code setup)
No written follow-up	60% of disputed claims	15-30% of claim value	$0 (email discipline)
Missing schedule analysis	35% of delay claims	30-50% of claim value	$10,000-$25,000 (analysis)
Ignoring sub insurance	28% of liability claims	100% of sub's share	$3,000/year (tracking software)
Premature litigation	15% of claims over $500K	20-40% in excess legal fees	$5,000 (mediation first)

Mistake 5: Ignoring Subcontractor Insurance Compliance

A subcontractor causes a $2 million property damage claim. The GC discovers the sub's insurance lapsed two months ago. The GC's own policy responds, driving up premiums and experience modification rates for years.

This mistake is entirely preventable. Verify sub insurance at contract signing and monitor it throughout the project. Check that additional insured endorsements, indemnification agreements, and waiver of subrogation endorsements are in place.

The fix. Use automated compliance tracking. SubcontractorAudit monitors certificate expiration dates, sends renewal alerts, and flags coverage gaps in real time. Manual tracking with spreadsheets breaks down on projects with more than 20 active subs.

Mistake 6: Accepting Verbal Change Directives

The owner's representative says "go ahead and do the extra work, we will figure out the cost later." The contractor proceeds. Months later, the owner denies authorizing the work.

Verbal change directives create some of the most contentious construction claims. Without written authorization, the contractor bears the burden of proving that the work was directed by someone with contractual authority.

The fix. Require written change directives before starting any work outside the contract scope. If the owner insists on a verbal directive due to urgency, confirm it in writing the same day. Cite the specific work directed, who directed it, and note that you will submit a formal change order proposal.

Mistake 7: Jumping to Litigation Too Early

Some GCs treat litigation as the first option instead of the last. This approach wastes money and damages relationships.

Mediation costs $5,000-$20,000 and resolves 75-85% of construction disputes. Litigation costs $50,000-$500,000+ and takes 18-36 months. The math favors mediation in almost every scenario.

The fix. Follow the contract's dispute resolution ladder. Negotiate directly first. If that fails, propose mediation. Reserve arbitration and litigation for claims where the other party refuses to engage in good faith or where the stakes justify the expense.

Mistake 8: Failing to Update the Claims Register

A project has three active claims and two potential claims. Nobody tracks them in one place. The PM manages them in separate email threads. When leadership asks for project risk exposure, the answer takes three days to compile.

The fix. Maintain a single claims register for every project. Update it weekly. Include the event date, notice date, estimated value, current status, and next action. Review it at every project meeting. This register gives leadership real-time visibility into risk exposure.

FAQs

What is the biggest mistake GCs make with construction claims? Missing the notice deadline is the most damaging mistake because it can result in a complete waiver of an otherwise valid claim. Twenty-two percent of denied claims fail solely due to late or missing notice. The fix is straightforward: send written notice within 48 hours of any event that could lead to a claim.

How much does poor claims management cost a general contractor? Contractors without formal claims procedures leave an average of 34% of legitimate claim value unrecovered. On a $500,000 claim, that represents $170,000 in lost recovery. Add legal fees for poorly documented claims, and the total cost of poor claims management often exceeds 5% of annual revenue.

Why do verbal change directives cause problems? Verbal directives create disputes because both parties remember the conversation differently. Without written authorization, the contractor must prove that the work was directed, that the person giving the direction had authority, and that the scope matches the claim. Written confirmation the same day eliminates these proof problems.

Should I always hire a lawyer for construction claims? Not always. Claims under $50,000 are often resolved through direct negotiation. Claims between $50,000 and $200,000 benefit from legal review but may not require full representation. Claims over $200,000 generally need legal counsel, especially if formal dispute resolution is likely.

How can I track claim costs separately from project costs? Set up dedicated cost codes in your accounting system within 24 hours of a claim event. Create separate codes for labor, equipment, materials, and subcontractor costs related to the claim. Instruct field staff to charge all claim-related work to these codes. Review the charges weekly for accuracy.

What is a claims register and why do I need one? A claims register is a project-level log that tracks all potential and active claims in one document. It includes event dates, notice dates, contract references, estimated values, and current status. It prevents claims from falling through the cracks and gives leadership visibility into project risk. Update it weekly and review it at every project meeting.
