The others are scattered across the core clauses, the main options, and Contract Data — and missing any of them has consequences. As Glenn Hide of GMH Planning noted in CECA Bulletin 34 on NEC4 contract timescales, there is a wide range of response periods across the contract that practitioners routinely overlook.",

      "content": "## Lack of Response to Contractor Application\n\nThe Project Manager should certify a payment within one week of the assessment date. In the UK where Y(UK)2 applies, the Contractor’s application for payment would become the Payment Notice if the Project Manager does not respond to the Contractor’s application. The Client would therefore become legally bound to pay the amount due assessed by the Contractor. This is based on the UK, but other jurisdictions may have their own rules governing construction contracts that would need to be checked.\n\n## Summary [...] 1. Programme: if the Project Manager does not respond to a programme issued for acceptance within two weeks, the Contractor may notify that lack of response. The clause does say ‘may’ in as much as it is not an obligation, but the response is necessary to trigger the next part of this process. To ‘notify’ is obviously in writing and where the Scope states one, it is issued within the cloud-based system that has been agreed to be used. If the Project Manager does not respond to that notification reminder within a further week, then the programme is treated as being accepted (i.e. deemed accepted). [...] 2. Compensation event notification: If the Project Manager does not respond to a notified compensation event within one week, then the Contractor may notify that fact.  If they do not respond within a further two weeks from the notification, the principle that the event is a compensation event is treated as having been accepted. The Contractor may now also submit the quotation.",
