Check a Primavera P6 programme against the NEC3 / NEC4 acceptance requirements before you submit it. The tool assesses the schedule you upload against Clause 31.2 and, where a previous programme is provided, the revision requirements of Clause 32.1 — then tells you which of the four Clause 31.3 grounds a Project Manager could use to reject it. Set your Contract Data, confirm the items an XER can’t show, and run the check. Everything runs in your browser; nothing is uploaded to a server.
Assessment set-up
The programme file cannot tell us everything the contract requires. Set the Contract Data and reporting cycle so the check compares the programme against the right benchmarks.
Manual confirmations
Tick each item that is genuinely present and correct in the submission. An unticked box is treated as not provided — which is itself a common ground for non-acceptance.

Analysis support only: This is an automated indicative check of a programme against the NEC acceptance requirements. It is decision support, not a formal acceptance, a legal opinion, or a substitute for the Project Manager’s assessment under the contract. Independent expert review is recommended before relying on it in any contractual context.
Clause 31.3 grounds for non-acceptance
A Project Manager may reject a programme only on the four grounds set out in Clause 31.3. Each is assessed below against the results of the check.
