Planning advice for contractors

Most contractors come to NEC with JCT instincts: claim extensions retrospectively, reconstruct delay at the end, argue from the completion date. NEC works the opposite way. Time entitlement is built prospectively, one compensation event at a time, against planned completion at the dividing date. Get that wrong, and you are fighting uphill for every week. Get it right, and the contract does the heavy lifting. This is the complete contractor guide to NEC delay analysis and exte

Most contractors treat clause 31 as a procedural hurdle to clear at the start of the job. Submit the programme, wait for acceptance, move on. That approach quietly hands commercial control to the project manager. This article explains what the accepted programme actually protects, how the deemed acceptance mechanism works, and why a programme that was accepted at mobilisation provides almost no commercial protection by month six.

The programme schedule goes to the planner. The programme narrative goes to the decision-maker. Most contractors write one that describes the Gantt rather than argues the case. Here is why that costs them at clarification and what a strong narrative actually does.

On NEC Options C and D, real cost can still become vulnerable when the accepted programme and the cost record stop telling the same story. This article looks at the hidden commercial fracture between planning and QS records, and why that is where Defined Cost recovery often starts to fail.

For mechanical, electrical, civil, groundworks and fit-out contractors, the accepted programme often only becomes important when change or delay lands on a programme that no longer reflects the live job. This article explains why that drift matters under NEC and how programme protection is often lost by degrees, not all at once.

Many specialist subcontractors run NEC packages without a full planning team. The issue is not team size. It is whether the programme stays live, current and commercially usable while the job is moving.

Where multiple compensation events arise under NEC4, separate assessment is usually the safer route. This guide explains the accepted programme, the dividing date, and why one blended impact programme can weaken traceability.

Time Risk Allowance and terminal float both create breathing space in an NEC programme. That is why contractors often confuse them. But they sit in different places, serve different purposes, and blurring the line between them weakens programme acceptance, distorts the update cycle, and makes compensation event assessments harder to defend. This article explains what each one actually is, how they connect without being the same, and why keeping the distinction clean matters c

Clause 15 only works when early warnings trigger decisions and programme movement. Here’s a quantified register method and weekly rhythm you can run on real jobs.
