Construction claims best practices separate GCs who manage disputes profitably from those who bleed money on every claim. A 2025 FMI Capital Advisors study found that contractors with documented claims procedures spend 62% less on dispute resolution than those who handle claims ad hoc. The difference comes down to process, not luck.

This guide lists the best practices that protect your margins when construction claims arise. Each practice is actionable and based on real project outcomes.

1. Send Written Notice Within 48 Hours

The clock starts when you become aware of a claim event. Most contracts require written notice within 7 to 21 days. Best practice is to send it within 48 hours.

Early notice does three things. It preserves your contractual rights. It puts the other party on alert to preserve their own records. And it creates a timestamp that supports your timeline later.

Your notice should cite the specific contract clause, describe the event, and state that you are reserving your right to claim additional time, money, or both. Keep it factual. Do not estimate damages in the initial notice.

2. Separate Claim Costs From Day One

Open dedicated cost codes for claim-related work the day the event occurs. Track labor hours, equipment use, materials, and subcontractor costs separately.

Blended cost tracking is the number one reason claims lose value during negotiation. When you cannot prove which costs relate to the claim event, opposing counsel will challenge every dollar. Separate cost codes make your damage calculation defensible.

3. Photograph Everything With Timestamps

Take photos before, during, and after every claim event. Use a device with GPS and timestamp capability so the metadata proves when and where each photo was taken.

Photograph from consistent vantage points. If you document a differing site condition, shoot from multiple angles and include a measuring reference. A 2024 survey of construction arbitrators found that photographic evidence was the most persuasive form of documentation in 73% of cases.

4. Maintain Daily Logs Without Gaps

Daily logs should cover weather, crew size, equipment on site, work performed, visitors, deliveries, and any issues or delays. Complete them the same day. A log entry written a week later loses credibility.

Digital log platforms with automatic timestamps are harder to challenge than handwritten notes. The log does not need to be lengthy. It needs to be consistent, accurate, and contemporaneous.

5. Build Your Schedule Analysis Early

Do not wait until mediation to run a schedule analysis. Update your project schedule within a week of a delay event. Show the critical path impact while the facts are fresh.

Retrospective schedule analyses prepared for litigation carry less weight than real-time updates. Arbitrators and judges give more credit to schedules that were updated as the project progressed.

Schedule Analysis Type	Weight in Disputes	Cost to Prepare	Best Use Case
Contemporaneous update	High	$2,000-$5,000	First response to delay event
Time impact analysis	High	$10,000-$25,000	Formal claim submission
As-planned vs. as-built	Medium	$15,000-$40,000	Claims with multiple delay events
Collapsed as-built	Medium-High	$20,000-$50,000	Complex multi-party disputes
Windows analysis	Highest	$30,000-$75,000	Large-scale disputes, litigation

6. Follow the Contract's Dispute Resolution Steps

Most contracts specify a resolution sequence: negotiation, then mediation, then arbitration or litigation. Skipping steps can waive your rights or delay resolution.

Read your contract's dispute resolution clause before a claim arises. Know the deadlines, the required steps, and who makes interim decisions. On AIA contracts, the architect typically makes initial claim decisions. On ConsensusDocs, the parties negotiate directly first.

7. Quantify Damages With Supporting Data

Your claim should include a clear, line-item damage calculation. Every number needs backup.

For delay damages, show extended general conditions costs: supervision, trailer rental, insurance, utilities, and equipment. For productivity losses, compare planned production rates to actual rates during the affected period. For material cost increases, provide invoices showing the price difference.

Round numbers invite scrutiny. A claim for "$500,000 in delay damages" looks like a guess. A claim for "$487,340 in delay damages" backed by 14 cost exhibits looks like a calculation.

8. Verify Subcontractor Insurance Before Claims Arise

A claim involving an uninsured subcontractor puts the entire financial burden on the GC. Verify that every sub maintains the coverage required by their subcontract throughout the project.

Check for general liability, workers' compensation, auto liability, and umbrella coverage. Confirm additional insured endorsements and surety bond requirements. SubcontractorAudit automates this verification so you catch lapses before a claim occurs.

9. Negotiate Before You Litigate

Direct negotiation resolves 70% of construction claims at a fraction of the cost of formal dispute resolution. Before engaging lawyers, sit down with the other party and present your evidence.

Prepare a clear, factual presentation. Show your documentation, your cost calculation, and your contract basis. Avoid emotional arguments. The goal is to reach a fair resolution, not to win a debate.

If direct negotiation stalls, mediation has a 75-85% success rate in construction disputes and costs 90% less than arbitration.

10. Create a Claims Register for Every Project

Maintain a running log of all potential and active claims on each project. Include the event date, notice date, contract clause, estimated value, and current status.

A claims register prevents issues from falling through the cracks. Review it at weekly project meetings. Update it when circumstances change. It also gives your leadership team visibility into project-level risk exposure.

FAQs

What is the most important construction claims best practice? Timely written notice is the most critical practice. Without proper notice, even a legitimate claim can be denied on procedural grounds. Send written notice within 48 hours of becoming aware of a claim event, citing the specific contract clause and describing the circumstances.

How do I separate claim costs from regular project costs? Set up dedicated cost codes in your accounting system the day a claim event occurs. Assign all labor, equipment, materials, and subcontractor costs related to the claim to these separate codes. This separation makes your damage calculation defensible during negotiation or dispute resolution.

Should I hire a claims consultant or handle claims in-house? For claims under $100,000, experienced GCs can often handle them in-house with legal review. Claims between $100,000 and $500,000 benefit from a claims consultant who specializes in schedule analysis and damage quantification. Claims over $500,000 typically require both a consultant and legal counsel.

How do I calculate delay damages on a construction claim? Calculate extended general conditions by identifying the daily cost of maintaining your project presence during the delay period. Include supervision salaries, trailer and equipment rental, insurance, utilities, and bond costs. Multiply the daily rate by the number of compensable delay days identified in your schedule analysis.

What role does the project schedule play in construction claims? The project schedule is the foundation of delay claims. You must prove that the delay event affected the critical path of the project. A contemporaneous schedule update showing the impact carries more weight than a retrospective analysis. Without schedule evidence, delay claims are difficult to prove.

How can I prevent construction claims on my projects? Invest in pre-construction review, clear contract language, regular progress meetings with documented minutes, and subcontractor compliance tracking. Process change orders within 14 days. Address field issues in writing the week they arise. These practices prevent 60-70% of potential claims from ever reaching the formal notice stage.
