What a superintendent actually does under AS 4000, and why the builder should not choose one.
Every AS 4000 contract names a superintendent. Most boards signing one could not say what the role does, who it works for, or why it matters which side of the table it comes from. This is the plain answer.
The role the contract creates
AS 4000 is one of the most widely used general conditions of contract for building work in Australia, and AS 4902 is its design and construct cousin. Both create a role called the superintendent. The superintendent is not a party to the contract. The parties are the owner, called the Principal, and the builder, called the Contractor. The superintendent is the person the Principal appoints to administer the contract between them.
That word, administer, hides a great deal. In practice the superintendent is the person who decides, month after month, what the builder is paid, whether the builder gets more time, what a change to the work is worth, and when the building is finished. Those four decisions are where the money in a construction contract moves. Whoever makes them shapes the outcome more than the architect, the quantity surveyor or the lawyer.
Two hats, one person
The general conditions give the superintendent two kinds of function, and the distinction matters.
The first is as the Principal's agent. When the superintendent issues a direction, orders a variation, or tells the builder how the site is to be managed, the superintendent is acting for the owner. The builder must comply, and the owner is bound by what its superintendent directs.
The second is as a certifier. When the superintendent assesses a progress claim, determines an extension of time, values a variation, or certifies practical completion, AS 4000 requires the Principal to ensure that the superintendent fulfils all aspects of the role reasonably and in good faith, and it fixes the time the superintendent has to respond to a progress claim, an extension of time claim and a request for a certificate of practical completion. That obligation exists because the builder has agreed to let one person, appointed and paid by the other side, decide what it is owed. The price of that arrangement is that the decisions must be reasonable, made in good faith, on time and reasoned.
A good superintendent lives comfortably in both hats. The owner's interests are protected by rigour, not by bias. A certificate that could not survive scrutiny protects nobody, least of all the owner who will end up defending it.
What the superintendent actually issues
On a typical club or hospitality project the superintendent's month looks like this.
- Progress claim assessment. The builder claims for work done to a date. The superintendent measures what was actually done, applies the contract sum, the approved variations and the retention or security provisions, and issues a certificate or payment schedule stating what is payable and why any amount claimed is not. In New South Wales and Queensland that response also has to satisfy the Security of Payment legislation, and it has to be served inside a statutory period. Miss the period and the owner can become liable for the whole amount claimed.
- Variations. When the owner wants something changed, or the site throws up something nobody expected, the superintendent directs the variation in writing before it is built, and values it. Without a direction the builder is not entitled to be paid for it; without a valuation the account drifts.
- Extensions of time. When the builder claims delay, the superintendent assesses whether the cause is one the contract recognises, whether the builder gave notice in the way and within the time the contract requires, and whether the delay actually affected the critical path. The determination is issued in writing with reasons, because it decides whether liquidated damages apply.
- Notices and directions. Latent conditions, inclement weather, defective work, safety, show cause. Each has a procedure and most have a time bar.
- Practical completion. The most valuable certificate on the project. It starts the defects liability period, releases security and ends liquidated damages. It is issued when the superintendent is satisfied, on inspection, that the works are complete except for minor defects and that the tests and documents the contract requires have been dealt with, not simply because the builder has asked for it.
- Final certificate. The account closed, security released, the file complete.
Behind those instruments sit the registers: variations, extensions of time, notices, requests for information, defects. And behind the registers sits the report to the board each month, in language directors can act on.
Why it matters who chooses the superintendent
On many smaller projects the superintendent is the architect, because the architect is already there. On some, a builder will suggest a superintendent, or offer to have its own contracts administrator "handle the paperwork". Both arrangements can work, and both carry a structural problem the owner should see clearly.
The architect's interest is in the design being built as drawn. When a variation is needed because the drawings were incomplete, the architect is being asked to certify a cost that flows from the architect's own work. Most handle it honourably. None are independent.
The builder's contracts administrator works for the builder. The builder's commercial success depends on the value of variations, the extensions of time granted and the timing of practical completion. Asking that person to certify those things for the owner is asking them to referee a match they are playing in.
An independent superintendent, appointed by the owner and engaged by nobody else on the project, has one interest: administering the contract properly. That is what the general conditions assume, and it is what the owner is paying for.
What a board should ask before it signs
- Who is named as superintendent in the contract, and who do they work for on this project?
- Has anyone read the special conditions? Australian Standard contracts are routinely amended, and the amendments usually shift risk to the owner. Every clause the superintendent relies on must be read in the executed document, not the standard form.
- What are the response periods for payment claims and extension of time claims, and who is diarising them?
- How will the board hear about variations: before they are built, or in the final account?
- Who inspects for practical completion, and what documentation must the builder hand over before the certificate issues?
If the answers are not clear before the contract is signed, they will be expensive to discover afterwards.
