Why a Letter Alone Isn't Enough
A delay claim letter puts the other party on notice. It preserves your contractual right to request a time extension or recover delay damages. But the letter itself is just the starting point.
To actually win a delay claim — whether in negotiation, mediation, or litigation — you need contemporaneous documentation that corroborates every assertion in the letter:
- Daily LogsTimestamped records of weather conditions, workforce, equipment, and work performed. The backbone of any delay claim.
- PhotosGPS-tagged, dated site photos showing conditions at the time of the delay. Visual evidence is harder to dispute.
- Schedule ImpactUpdated CPM schedules showing how the delay pushed the critical path. The letter references impact — the schedule proves it.
- CorrespondenceEmails, RFIs, and submittals showing when information was requested and when (or if) it was received.
The bottom line
Contractors who keep consistent daily documentation recover an average of 30-50% more in delay claims than those who rely on letters and memory alone. The letter opens the door — your daily logs are what you walk through with.
How to Use These Templates
Choose the right template
Match the delay type to the corresponding letter. If multiple delay types apply, use the primary cause and reference secondary causes in the body.
Fill in the bracketed fields
Replace all [bracketed placeholders] with your actual project details. Reference your specific contract section for excusable delays or time extensions.
Attach supporting documentation
Include daily logs, weather records, photos, and schedule analyses as attachments. The letter is the notice — the attachments are the evidence.
Send within the notice period
Most contracts require notice within 7-21 days of when the delay becomes known. Check your contract's specific notice requirements. Late notice can waive your claim.
Frequently Asked Questions
When should I send a delay claim letter?
Send a delay claim notice as soon as you become aware of a delay that will impact the project schedule. Most contracts require written notice within a specific timeframe (often 7-21 days). Failing to send timely notice can waive your right to a time extension or delay damages.
What should a construction delay claim letter include?
A delay claim letter should include: the specific contract provision you are invoking, a description of the delay event, the dates affected, the impact on the critical path schedule, supporting documentation references (daily logs, weather records, photos), and the relief you are requesting (time extension, cost recovery, or both).
What is the difference between excusable and compensable delays?
An excusable delay entitles the contractor to a time extension but not additional compensation. Weather delays and acts of God are typically excusable. A compensable delay entitles the contractor to both a time extension and additional payment. Owner-caused delays (late decisions, scope changes, denied site access) are typically compensable. Non-excusable delays are the contractor's responsibility.
Do I need daily logs to support a delay claim?
Yes. Daily jobsite logs are the single most important piece of supporting documentation for delay claims. They provide contemporaneous evidence of weather conditions, workforce presence, equipment usage, and work progress. Without daily logs, a delay claim letter is just an assertion — with them, it becomes documented evidence.
What contract provisions cover construction delays?
Common contract provisions include: AIA A201 Section 8.3 (Delays and Extensions of Time), ConsensusDocs 200 Section 6.3 (Delays), and FAR 52.249-10 (Default for federal projects). Custom contracts typically have a "Time Extensions" or "Excusable Delays" clause. Force majeure clauses may also apply to supply chain disruptions and extreme weather events.
