Indicative grand total
This is an indicative estimate, not a final quotation. GST is extra. Contingency is 5% of section billing and overhead is 8% of the same bill. The figure uses thumb-rule quantities. Actual cost will vary with the final drawings, soil conditions, and market rates.
The detailed bill of quantities is a separate signed-in workspace. It is not produced by the package rate on the card.
