NEC3 — common questions

Where you’ll meet it: Engineering and infrastructure — power, water, roads, rail and heavy civils. Widely used by state-owned entities (e.g. Eskom) and on donor-funded projects.

What is a compensation event?

A compensation event is the single route under NEC3 for adjusting the Prices and/or the Completion Date. There are no separate 'variations' or 'claims' — everything that changes cost or time is a compensation event, drawn from the closed list in clause 60.1. The contractor notifies the event and submits a quotation covering both the cost and the time effect together.

How long do I have to notify a compensation event?

NEC3 carries a well-known time bar: a compensation event must generally be notified within eight weeks of the contractor becoming aware of it, or the entitlement to more time or money is lost. This is one of the most important dates on the contract — diarise it and notify early, even if the full effect isn't yet clear.

What is the Accepted Programme and why does it matter?

The Accepted Programme is a live, contractually binding programme that the contractor keeps updated and the Project Manager accepts. Time impacts of compensation events are assessed against it, so it isn't a formality — it's the engine of the contract. Keep it genuinely current; a programme the Project Manager hasn't accepted weakens your position on delay.

What is an early warning?

Either party must give an early warning as soon as they become aware of anything that could increase cost, delay Completion or a Key Date, or impair performance. Early warnings feed a risk register and are discussed at risk-reduction meetings. Failing to give an early warning you should have given can reduce what you eventually recover on a related compensation event.

Assessment is prospective — what does that mean?

Compensation events are assessed on a forecast of their effect at the time, not by a back-calculation after the work is done. You price the quotation on the expected cost and time impact. This rewards contractors who manage and quote promptly, and it's a key difference from contracts where claims are argued retrospectively at the end.

What are the main Options (A–F)?

NEC3 ECC has main Options that set the pricing mechanism: A (priced contract with activity schedule), B (priced contract with bill of quantities), C (target contract with activity schedule), D (target contract with bill of quantities), E (cost-reimbursable), and F (management contract). Option A and target Option C are the most common you'll meet on SA projects.

Who are the Project Manager and the Supervisor?

NEC3 splits the employer's administration between two roles. The Project Manager runs the commercial and programme side — accepting programmes, assessing compensation events, certifying payment. The Supervisor deals with quality and defects on site. Knowing which role to address a communication to matters, because notices to the wrong person may not count.
