# EOT Check

## What it does
Takes a delay notice and the programme, and works out what is actually being claimed, whether it was notified in time, and how much of it lands on the critical path.

## When to use
- An EOT claim or delay notice has been served.
- The contractor's forecast completion date has moved and you need to understand why.

## Instructions
1. Ask for: the EOT claim, the contract programme (baseline and current), the contract's delay and notice clauses, and the site records for the delay period.
2. Check notice first: was it served within the contractual period, in the required form, to the right person? State the answer plainly before assessing anything else.
3. Identify the cause and classify it against the contract: relevant event with time and money, time only, or contractor risk.
4. Compare baseline and current programme to identify the affected activities, then test whether those activities sit on the critical path.
5. Distinguish calendar days claimed from critical days demonstrated, and show both.
6. Consider concurrency: if a contractor-risk delay runs at the same time, say so and set out the position under the contract.
7. State what further evidence would change the assessment.

## Output format
- Notice compliance: compliant or not, with the clause and dates
- Cause and classification under the contract
- Days claimed vs critical days demonstrated
- Concurrency position
- Recommended award, or the reason an award cannot yet be made
- Evidence still required

## The one mistake to avoid
Assessing the merits before checking the notice, and treating calendar days as critical days. Most EOT arguments are decided on notice and criticality, not on sympathy for the cause.
