Planned gross margin on Australian civil and transport work

What it is. Mean margin excluding overheads, of contract value.

Range 6% to 9.89% (across studies)

Sample. 67 projects from one Australian contractor (9.89%); 8 Australian transport projects (almost 9%); six years of one contractor's ledgers (6% to 9%).

What it is not. Two of the three sources are one contractor's data each, and all three are the same research group. The docs page rounds this to 9%.
