An investigation was conducted to examine the influence of project size and the difference between base estimate and initial contract sum in predicting change order rates. The study was conducted on historical data of 45 projects in Northern Nigeria that were in progress from 2004 to 2014. Base on the study analysis, it was found that project size and the difference between base estimate and initial contract sum can be predictors of change order rates. The study concluded that despite the fact that cost overrun rate and change order rate are not identical, they can be predicted by the same factors.
