## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Construction & Infrastructure](https://ailawframework.com/practice/construction-and-infrastructure.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | Set the summary beside the programme and the site records and list each date, activity, or quantity that does not match, with the document name. Do not write a delay analysis or a claim letter. |
| What the lawyer must review | Entitlement to time or money is the contract’s clause, which the lawyer reads. 31 U.S.C. § 3905’s 7-day payment duty, on an agency construction contract, runs from satisfactory performance and from amounts the agency has paid the prime. It is not a test of who caused delay. 40 U.S.C. § 3133’s 90-day notice and one-year suit limit apply to a bond claim by a person who furnished labor or material, not to a delay claim between the parties. Formal Opinion 512 requires the lawyer to verify the tool’s dates before they are used. |

## Checking plan

- What the AI does: Set the summary beside the programme and the site records and list each date, activity, or quantity that does not match, with the document name. Do not write a delay analysis or a claim letter.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- No federal security-of-payment adjudication statute was opened. Do not invent a payment-schedule regime.
- A critical-path opinion is expert work. Federal Rule of Evidence 702 is the court rule if that opinion is later offered, and this check does not write it.
