Construction Overrun Risk
Predict cost overrun probability and quantify the most likely overrun amount. Rule-based risk scoring.
About construction cost overruns
Construction projects often exceed planned budgets due to scope changes, material and labour inflation, delays, and unforeseen site conditions. This tool uses rule-based risk scoring to estimate the probability of overrun and the likely overrun amount based on project type, size, and common risk factors.
Use the calculator to stress-test your project budget and set contingency reserves. Results are indicative; combine with expert judgement and historical data for critical decisions.
