FAQs
What does a quantity surveyor actually do?
A QS measures and estimates construction costs, prepares tender documents, manages contracts, and ensures you stay ATO-compliant—essentially acting as the project’s financial watchdog.
How much does it cost to hire a QS in Australia?
Fees vary by scope and project size, but expect 0.5–2 % of construction value for full-service engagements or $130–$250 per hour for ad-hoc advice.
When should I engage a QS?
Ideally at concept stage. Early cost modelling saves headaches later by aligning design aspirations with budget realities.
Do I need a QS for residential builds?
Yes—especially for duplexes, multi-unit developments or major renovations. A QS maximises tax-depreciation benefits and keeps builders honest on variations.
