Planning advice for contractors

A specialist M&E subcontractor with twenty years of delivery experience lost an NEC4 framework bid to a larger competitor with a thinner track record. The debrief was instructive. The gap was not price or technical approach. It was the planning and programme response. The larger competitor evidenced delivery confidence through a logic-linked tender programme. The specialist asserted it through a narrative of experience.

Most contractors treat time risk allowances as a presentational question: how much contingency to show and how to stop the project manager challenging it. The framing misses what TRA actually is. A time risk allowance is the only risk provision in the programme the contract explicitly protects: it is retained when compensation events are assessed, while risk hidden inside padded durations is silently consumed by the impact arithmetic, event after event.

A tender programme is required when the invitation to tender asks for one, and in practice when the quality evaluation scores it. Where neither applies it is still worth building, because it sets the durations behind every time-related cost in the price. This guide covers what a tender programme is, how it fits into the tender period, how it differs from the clause 31 programme after award, and a checklist to run before it goes in.

Give the same compensation event to two competent planners. Same accepted programme, same dividing date, same facts. One comes back with three weeks of delay to planned Completion. The other comes back with nine days. Both can defend their model. Neither has made an arithmetic error. The difference is five judgement calls that sit inside every NEC4 delay assessment, that the contract deliberately leaves open, and that most contractors make silently.

A specialist contractor wins an NEC package on the work it can do, and keeps the margin on something else: how the programme, the early warning rhythm and the change record hold up across the job. This is the operating model that decides which, phase by phase.

On NEC, M&E margin is often lost in the silent gap between a builder's delay and a contractor's commissioning window.

Specialist contractors rarely lose money on NEC jobs because they cannot build. More often, they lose it when the accepted programme stops reflecting reality and the change record is too weak to defend. This article looks at where that happens and how stronger programme discipline protects margin and repeat work.
