Client-approved change orders, 67 Australian public infrastructure projects

What it is. 10.6% of original contract value, client-approved change orders.

Sample. 67 completed public infrastructure projects from one contractor, Australia, civil, 2011-2014. Change orders totalled about AU$342m against about AU$3.2bn of original contract value, so 10.6% is a total over a total (the paper calls it a mean: average change orders of about AU$5.1m over average contract value of about AU$48.2m).

What it is not. SIZE OF THE POT, NOT A LOSS. No study measures how much of it a typical contractor fails to claim. Change orders were linked to HIGHER contractor margins, which is the opposite of a loss.
