      "content": "Dr Kings recommends that these assumptions focus on the most likely or best-case scenario. Overly cautious or worst-case assumptions tend to inflate quotes and slow things down – often unnecessarily. A balanced approach, built on open communication and fair assumptions, helps ensure quotations are realistic and that risk is managed proportionately.\n\n### Keeping on top of compensation events\n\nThe compensation event process follows four distinct stages: notification, quotation, assessment and implementation. Under standard NEC4 timescales, Project Managers have one week to respond to a notified compensation event, contractors have three weeks to submit their quotation, and Project Managers then have two weeks to respond. [...] This is where digital contract management systems add real value. Platforms like ours provide time-stamped, structured communication threads and allow instructions to be clearly documented and linked to related events. That means there’s never any ambiguity about what was instructed, when, or by whom. And if a dispute arises, there’s a reliable audit trail to fall back on.\n\n### When to propose before you instruct\n\nFor more complex or high-risk changes, NEC4 provides another useful mechanism: the proposed instruction. Clause 65.1 allows Project Managers to request a quotation for a potential change before deciding whether to issue the instruction. It’s a ‘look before you leap’ approach – giving both parties a chance to assess the implications before committing to the work. [...] 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.",
