A practical budget check
Use a current supplier or estimator rate to explore one work package. Choose a consistent unit: for example, floor area in m² and a rate per m².
Start with your own rate
No market price is assumed. Enter an excluding-GST rate from your project documents.
Allow for uncertainty
Add an allowance for this scenario. Contingency is not a substitute for complete scope or professional advice.
Review the full scope
Land, fees, site works and other trades are only included if your rate covers them. This is arithmetic planning, not a quote.
