An early warning identifies a developing risk so the parties can consider measures to reduce its effects. Under NEC it has a management purpose distinct from compensation-event notification. Giving one does not automatically satisfy every other notice requirement or establish an entitlement to extra payment. Record the risk, possible effects and proposed response.

It gives the required warning and identifies the installation activities at risk. 2. It separately checks whether the facts require another contractual notice. ### What this shows The warning supports mitigation, while the payment and time consequences remain separate contractual questions. ## Sources 1.
