27.4% of construction cost: Equipment and fuel as a share of the cost of road construction, Australia (2013 survey of road works) (Bureau of Infrastructure, Transport and Regional Economics (BITRE), 2013 to 2016; Australia; moderate confidence).
What it is. 27.4% of the total cost of road construction work: equipment hire and depreciation 21.69% plus fuel 5.76%.
Sample. Survey of road works by the federal transport research bureau, 2013. For private sector contractors alone (36 respondents) equipment and fuel are 27.60% of construction cost (hire and depreciation 21.53%, fuel 6.07%). State and territory road authorities report 27.70% and local governments 26.97%.
What it is not. Context only: how large plant and fuel are in the cost of road construction, 2013 mix, for roads only. It is not an overrun, an hours-over-allowance figure or a measure of standby, and not a share of contract value. Fuel alone is 5.76% of road construction cost, but only 0.79% in the state road authorities' own column and 8.05% in local governments' (Table B2), so it varies with who does the work.

Considered and set aside
- Australian Taxation Office: A tax credit in cents per litre (52.6 for off-road diesel in early 2026, 20.6 from April 2026). It is a rate on fuel bought, not a share of cost, and the schema has no per-litre unit.
- Australian Bureau of Statistics: The output price of road and bridge construction rose 6.0% over the year to September 2026, with a 4.5% jump in the June 2026 quarter. A price movement, not plant or fuel as a share of contract cost.
- Bureau of Infrastructure, Transport and Regional Economics (BITRE): Reports diesel and labour as the main contributors to the 2013-14 rise in index points; no cost share beyond the 2013 mix.
