Mean design error cost 23.44% of contract value on the civil engineering projects in a 139-project Australian sample

What it is. 23.4% of original contract value, cost of design errors on the civil engineering projects in the sample, as estimated by survey respondents.

Sample. The civil engineering subgroup of the 139 Australian projects in design_error_cost_au. The abstract does not give how many of the 139 were civil. Fit-out projects averaged 22.50% and projects above A$101 million 26.18%.

What it is not. Graded low because the subgroup size is not in the abstract, and the 2012 abstract on what appears to be the same sample says cost did not vary significantly by project type. Respondents' estimates, not cost records, and the carrier of the cost is not stated. Abstract only; full text not read. Whether the sampled civil projects were road, rail or utilities is not stated.
