Track Record of Accuracy

The AIA Professional Practice Handbook states, “Any estimator who brings 60% of projects within 5% of the low bid is doing better than can be expected. One project in 5 will fall outside of 10%.” How does CostPro measure up? Over 60% of our projects are within 5% of the low bid, and fewer than one in twenty exceeds 10%. Our batting average for all projects is 1.63% below the low bid.
