What a superintendent actually does, and when you need one

The superintendent is the most misunderstood seat at the table on a Victorian construction contract. What the role covers under AS 4000 and AS 4902, what it does not, and when appointing one protects an owner.

On a Victorian commercial building contract, the superintendent is the person named in the contract to administer it. The role is written into the Australian Standard forms (AS 4000 for construct-only, AS 4902 for design and construct) and into most bespoke contracts. It is also the most misunderstood seat at the table, because it sits between the owner and the builder and owes duties to both.

What the superintendent does

The contract gives the superintendent a list of functions. The ones that matter most to an owner:

  1. Certifying progress claims. The builder claims each month; the superintendent assesses what has been done and certifies what is payable. The owner pays the certified amount. An uncertified claim is not a debt.
  2. Assessing variations. When the scope changes, the superintendent directs the variation, assesses the builder's price and, where the parties disagree, determines a reasonable value.
  3. Ruling on extensions of time. The builder claims delay; the superintendent assesses whether the cause is one the contract allows and how many days it is worth. This decides who pays for delay, so it is where the money is.
  4. Directing the works. Instructions, clarifications, and the resolution of discrepancies between documents are issued through the superintendent.
  5. Practical completion and defects. The superintendent inspects, issues the certificate of practical completion, and administers the defects liability period through to final certificate.

What the superintendent does not do

The superintendent is not the owner's advocate. Under the Australian Standard forms, when the superintendent certifies, assesses or values, they must act honestly and fairly, and reasonably in the time they take. A superintendent who simply rules for the owner every time exposes the owner to a claim that the contract was not administered as agreed. The role is closer to a referee than a lawyer.

Nor is the superintendent the designer, the project manager or the building surveyor. On many projects the same firm holds two of those roles, which is fine as long as the contract says so, and everyone understands which hat is on for a given decision.

When you need one

If you have signed an AS 4000 or AS 4902 contract you already need one, because the contract will not work without the role being filled. The real question is who should hold it.

  • The architect is the traditional choice on construct-only contracts and works well where the architect is experienced in contract administration and has the time.
  • An independent superintendent makes sense where the owner wants a construction professional assessing claims and programme, where the architect is not administering the contract, or on design and construct contracts where the builder's designer cannot be the referee.
  • The owner's project manager can hold the role, but the contract should say so explicitly, and the person should be prepared to rule against the owner when the contract requires it.

Appointing a superintendent early, before the contract is signed, lets them shape the schedule of separable portions, the liquidated damages, the security and the payment terms so the contract is administrable rather than a document nobody has read.

What it costs, and what it saves

Superintendent fees on a commercial project typically run as a monthly fee through the construction period plus a defects-period retainer, set against the contract sum and the complexity. The saving is in the claims that are assessed properly rather than paid because nobody checked, the variations priced before rather than after the work, and the extension of time disputes that are resolved on the day rather than at the end.

Where Silverfox fits

Silverfox acts as independent superintendent on aged care, health and commercial development contracts in Melbourne and Central Victoria, including the 120 bed Whitehorse Aged Care facility at Nunawading and the 90 bed Granite Hills facility at Euroa. Because the same business also builds, our assessments of programme, claims and variations are grounded in how the work is actually done.
