Scope: Practical commentary on NEC4 ECC. Check the edition, selected options, Contract Data and amendments used on your project.
Begin with the contractual requirements
Read the applicable record obligations, main option and Scope. Avoid presenting a generic diary checklist as the full contractual requirement. Identify who produces each record, who reviews it and how it is retained.
A construction site diary can capture location, work undertaken, resources, progress, conditions, instructions and significant events. The detail should let someone who was not present understand what happened.
Connect the event to its effects
For a compensation event review, link the event and notification record to relevant programme and cost evidence. A diary entry may support an awareness chronology, but does not conclusively fix awareness or replace a valid notice.
Distinguish actual records from forecasts used in an assessment. Preserve the assumptions, programme version and basis of the calculation rather than presenting a retrospective total as the complete explanation.
Keep cost substantiation option-specific
The Disallowed cost definitions differ by main option. For NEC4 ECC Options C–E, clause 11.2(26) includes a records-related exclusion; Option F needs separate treatment. Good evidence supports review but does not turn an excluded cost into Defined Cost.
A missing daily entry is not the same as proof that no other evidence exists. Review the accounts and records as a whole against the applicable wording.
Build a record chain people can follow
- Use stable activity and location references.
- Record who made the entry and when.
- Keep photographs with context, not just filenames.
- Cross-reference instructions, notices and programme updates.
- Preserve revisions and identify later corrections.
- Make review responsibilities and unresolved queries visible.
Digital tools can make this easier to search and assemble. The underlying need for accurate information and responsible review remains the same.
Set a justified retention policy
Do not use a blanket rule of six or twelve years from Completion for every record. Under the Limitation Act 1980 in England and Wales, the ordinary simple-contract and specialty periods generally run from accrual of the cause of action, subject to the applicable rules and exceptions.
Set retention with the contract, jurisdiction, potential claims, insurance, statutory obligations and personal-data requirements in view. Preserve material relevant to an actual or anticipated dispute. A project-specific policy is more reliable than an unsupported universal deletion date.
