How to Write a Notice of Claim That Gets Taken Seriously

On public works construction projects, virtually every contract requires the subcontractor to provide written notice within a specified timeframe before pursuing a claim. Miss the deadline, and you may forfeit your right to recover — regardless of the merits. Provide notice that's vague or incomplete, and the other side will use it against you.

The notice of claim is not a formality. It's the single most important document in the claims process.

Timing: The Non-Negotiable Requirement

Your contract specifies when notice must be given — typically within 7 to 21 days of the event giving rise to the claim. This is not a suggestion. Courts and arbitrators routinely deny otherwise-valid claims because the notice was late.

Mark every notice deadline in your calendar when you sign the subcontract. When a potential claim event occurs — a change directive, a differing condition, a schedule impact — send notice immediately. Don't wait to see if the issue resolves itself. Don't wait until you can quantify the cost. You can always supplement later. You can't unsend a late notice.

What to Include

An effective notice of claim should contain:

- The date and contract reference. Identify the project, subcontract number, and the specific provision you're claiming under. - A clear description of the event. What happened? When? What contract provision was affected? - The impact on your work. How does this event affect your scope, schedule, or cost? - Reservation of rights. "We reserve the right to submit a detailed claim with full cost and schedule impact analysis upon completion of the affected work." - Reference to the contract notice requirement. "This notice is provided pursuant to Section [X] of the Subcontract."

Keep the notice factual and professional. Avoid blame, emotional language, or legal threats. The notice is a record, not an argument.

The Follow-Up

A notice is just the beginning. After providing timely notice, you must:

- Continue documenting the cost and schedule impact daily. - Submit a detailed claim with supporting documentation within the contractual timeframe. - Respond to any GC requests for additional information promptly. - Keep copies of everything — the notice, the claim, all correspondence, and all supporting documents.

The subcontractors who win claims are the ones who start documenting on day one. The notice is your starting gun.

The Bottom Line

A notice of claim is not a letter of complaint. It is a legal document that preserves your right to recover money you are owed. Under PCC §9204, the claim process for public works projects follows a defined timeline: the contractor submits a written claim to the public entity, the entity responds within 45 days, and if unresolved, the parties proceed to meet-and-confer and potentially mediation before litigation.

Missing the notice deadline can waive your claim entirely, regardless of how strong your position is. File on time, include the right content, follow up in writing, and treat the notice as the legal instrument it is. The subcontractors who get paid on disputed work are the ones who followed the notice requirements to the letter.
