NEC4 Accepted Programme

Under an NEC4 Engineering and Construction Contract, the Accepted Programme is the working version of the programme that the Project Manager has accepted under Clauses 31 and 32. It sits at the centre of how NEC4 manages time: compensation events are assessed against it, completion dates are tracked against it, and the Contractor is required to submit revised programmes at regular intervals to keep it current. It is not simply a Gantt chart — NEC4 specifies what an Accepted Programme must contain, including planned completion, the order and timing of operations, float, time risk allowances, and the dates on which the Contractor plans to meet each Key Date.

The Accepted Programme is a live document. Every time a compensation event is implemented, the programme should be updated to reflect the agreed change. Contractors are required to submit revised programmes at the interval stated in the Contract Data (typically every four to eight weeks), and the Project Manager must either accept the revised programme or give reasons for not accepting it. Failing to maintain a current Accepted Programme is a common trigger for disputes — if there is no agreed reference programme, assessing compensation events or delay claims becomes a retrospective exercise rather than a contemporaneous one.

For project controls teams, the Accepted Programme is the single point of truth for time management on an NEC4 contract. It should be produced to a schedule quality standard (DCMA 14-point compliant, logic-linked, resource-loaded where required), updated with actuals and re-forecasts at each submission cycle, and version-controlled so every previous accepted programme is retrievable. On programmes where the Accepted Programme is treated casually — submitted late, updated inconsistently, or not reconciled to compensation events — the contract loses its primary time-management discipline.
