What does the NEC4 publisher FAQ explain?
The NEC4 ECC FAQ explains that the total cap in X18.5, when selected, subsumes losses covered by X18.2, subject to the excluded matters in X18.5. It also discusses blank entries for X18.2, X18.3 and X18.4 in relation to that total cap. This is the publisher's stated NEC4 example, not a conclusion about a differently amended tender.

Which fields prevent the limits being combined incorrectly?
Use the exact edition and actual clause references from the tender. A headline percentage without its denominator and exclusions is not a complete exposure statement. Preserve blanks as unanswered entries rather than enter a convenient number.
| Record | Input to preserve | Review question |
|---|---|---|
| Contract basis | Form, edition and amendments | Is this NEC4 ECC or another document? |
| Selected option | Actual X18 selection and source | Does the tender include the option? |
| Category limit | Category, amount and denominator | Which losses fall within the limit? |
| Total cap | Actual total cap entry and basis | How do category limits sit within it? |
| Excluded matters | Exact exclusion references | Which exposures sit outside the total cap? |
| Blank entry | Blank and source location | What is the actual contractual consequence? |
| Advice | Reviewer decision and assumptions | Which issue remains unresolved? |
Why is adding subcaps unsafe as a spreadsheet shortcut?
Illustrative example. A fictional review sheet records a total cap of 100 abstract units and two category limits of 40 and 70. Adding the categories gives 110, but does not prove that the total cap has become 110. Nor does the total cap prove that every possible liability is limited to 100.
The qualified reviewer must assess the actual category coverage, total cap and exclusions. The invented numbers show a document-interpretation question, not a prediction of claim recovery, insurance payment or enforceability.
How should the bid decision be recorded?
Keep the source entries, unresolved wording and proposed clarification together. Distinguish the reviewer's approved interpretation from an estimator's provisional assumption. Do not describe a proposed amendment as accepted merely because it appears in a departures schedule.
Retain the insurer's or adviser's separate review where needed. A liability cap entry is not a complete insurance analysis. If the form or edition changes, recheck the clause structure rather than transfer NEC4 clause numbers into another contract. This preparation register does not submit notices or settle contractual positions.
Common questions
What else should the bid team know?
Does a blank category limit mean zero liability?
Do not infer that. Obtain advice on the actual selected and amended contract.
Should category caps be added?
Do not add them without an approved interpretation of how they interact.
Is the total cap a complete insurance answer?
No. Insurance and excluded exposure require separate qualified review.
