“We sent an early warning” isn’t the same as “we notified a compensation event”.
Under NEC4 ECC, these processes serve different purposes.
An early warning flags a matter that could affect cost, Completion, a Key Date or the performance of the works. It gives the team an opportunity to reduce the risk.
A compensation event notification deals with an event that has happened—or is expected to happen—and is believed to qualify under the contract.
For groundworks and civils teams, the practical check is simple:
• Raise risks promptly through the correct contractual channel.
• Review separately whether a compensation event notification is required.
• Where both notifications are required, issue them separately.
• Record the actions agreed and follow them through.
Don’t assume an entry in the Early Warning Register has completed the compensation event notification process.
Check your contract and amendments, including the applicable notification requirements.
