Here is how to make your claims inevitable.

As a subcontractor, if you're not issuing a notice of change within 48 hours, you're basically volunteering to fund the change yourself. Most subcontractors treat notices like admin we'll catch up on later when we get a chance to do it. Early notice is actually leverage because it locks the event in while everyone still remembers it and before the story gets rewritten over time. Here's the kicker: you don't need the perfect claim on day one. You just need a timestamp. What has changed? When did it happen? Why it impacts time and cost, and that you're reserving your rights. That's what you're trying to do, because once the paper trail exists, everything downstream gets easier. Variation pricing, EOT pricing, the approvals don't feel like arguments, they feel like just a process that you're going through. You missed the notice window and now you're not really managing the contract anymore, you're negotiating from a place of weakness, trying to prove something after the fact. The best operators don't fight harder for claims, they make the claim inevitable by getting the notice in early.
