Every AS 4000 contract assumes a superintendent is administering it. Here is what that actually involves, month to month — and what goes wrong when nobody does it properly.

1. Progress claims: the monthly discipline

Each month the contractor claims for work done. The superintendent assesses what has actually been performed and certifies payment accordingly — on the contract’s timeframes, which in Queensland interact with security of payment legislation where response windows are short and missed deadlines can convert a claim into a debt. Certifying accurately and on time is the single most valuable thing a superintendent does.

2. Variations: entitlement before pricing

A variation claim gets two questions, in order. Is the contractor entitled — is this actually a change to the contracted scope, or something they already priced? Only then: is the pricing right? Owners without a superintendent routinely pay for “variations” that were always in scope, at prices nobody scrutinised.

3. Extensions of time: answer or pay

Delay claims have contractual machinery — notice requirements, qualifying causes, assessment timeframes. Under most AS forms, ignoring an extension of time claim is the worst available response: unanswered claims can become deemed entitlements, and with time goes money, through delay damages or lost liquidated damages.

4. Directions, quality and the record

The superintendent issues directions and instructions under the contract, monitors quality against the specification, and — quietly, continuously — builds the record: what was directed, what was claimed, what was certified, and why. If the project ends in dispute, that record is the difference between a defensible position and an expensive argument.

5. Completion: where discipline pays twice

Practical completion assessed against the contract, not the contractor’s schedule. Defects documented and pursued through the defects liability period. Final claim reconciled against every certificate that came before it, and the final certificate issued when it is earned. Projects that drifted through stages 1–4 pay for it here.

The independence point

AS 4000 requires the superintendent to act honestly and fairly in assessing and certifying. The principal appoints and pays the superintendent, but certification is not advocacy — and that is a feature. Fair certificates are the ones that survive scrutiny.
