That is one of more than 30 time obligations in the NEC4 Engineering and Construction Contract. 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. [...] ## Deemed Acceptance: When Silence Becomes Consent\n\nNEC4 contains specific provisions that treat a party's failure to respond as agreement to the other party's position. These are not general principles — they apply only where the contract explicitly creates the deeming mechanism. There are two in the CE process.\n\n| Situation | Deemed Outcome | Clause | Automatic? |\n ---  --- |\n| PM does not respond to CE notification within one week | Notification treated as accepted | 61.4 | Yes — no further action needed |\n| PM does not respond to CE quotation within two weeks | Quotation treated as accepted | 62.6 | No — Contractor must notify the PM |\n| PM does not respond to revised CE quotation within two weeks | Revised quotation treated as accepted | 62.6 | No — Contractor must notify the PM | [...] Fixed periods written into the contract clauses. These are the same on every NEC4 ECC project regardless of what the parties agree in Contract Data. The most commercially significant are in the compensation event procedures: the eight-week notification window (clause 61.3), the one-week PM response to a CE notification (clause 61.4), the three-week quotation period (clause 62.3), and the two-week PM response to a quotation (clause 62.6). The PM's two-week acceptance window for a programme submission (clause 31.3) also falls in this category. These periods cannot be varied by Contract Data.",

[...] For straight forward work, the NEC4 ECC gives Project Managers the authority to issue instructions under clause 14.3, allowing them to change the Scope of the works. However, where that change affects time or cost, it must also be notified as a compensation event under clause 61.1. This is then followed by a quotation request using clause 61.2. Missing any of these steps – or doing them out of order – risks confusion and non-compliance. One common mistake Dr Kings highlighted is when a compensation event is notified before the actual instruction has been issued, or when no instruction is given at all. In both cases, the communication lacks contractual standing. Both steps must be followed.",
