Quantity surveyor

A construction cost professional who measures and values building work, often used by banks to verify each stage of a build before releasing the next drawdown.

Definition

A construction cost professional who measures and values building work. On bank-funded builds, a quantity surveyor or valuer often inspects each stage and confirms the work matches the progress claim before the bank releases the drawdown. Owners funding a build themselves can engage one independently to verify a stage before releasing payment.

Why it matters

A quantity surveyor is the independent set of eyes that confirms a stage has actually been reached before money is released for it. On bank-funded builds, this verification is built into the drawdown process. For owners funding a build themselves, engaging a quantity surveyor or independent inspector for a few hundred dollars per stage is a way to verify progress before releasing a payment, rather than relying only on the builder's word.

How it works in practice

On a construction loan, when the builder claims a stage, the bank engages a quantity surveyor or valuer to inspect the site and confirm the work matches the claim. The bank releases the drawdown once the report is satisfactory.

Owners funding a build directly can engage a quantity surveyor or independent inspector themselves to check each stage before releasing the corresponding progress payment. The cost is small relative to the payment being released and gives an independent check on whether the stage is genuinely complete.

Common misconceptions

A quantity surveyor checks build quality

Their core role is measuring and valuing work and confirming a stage has been reached. Confirming that work meets building standards is a building inspector's role, though some professionals do both.

Only banks can use a quantity surveyor

Owners funding a build themselves can engage one independently to verify a stage before releasing payment.
