This post is the third installment in a series of posts about AACE’s 5 Estimating Classes. Designed for the new construction employee (engineer, estimator, and field personnel), we will take a high-level look the five types of estimates.
One of the ways that HD Project Cost Management software is unique is that it can handle the full gamut of estimate types, everything from Class 5 through Class 1.
The Class 3 or “Authorization” estimate is much more definitive than Classes 4 and 5. A C3 estimate is nearing the 50% definition mark, with anywhere from 10-40% of the project defined. Budget, appropriation, and control are key reasons for building a C3 estimate. Having completed the C4 estimate, we determined that the project will proceed to the C3 stage. With the C3 estimate, we’re beginning to nail down the entire scope of the project, and data included in the C3 estimate will be used against the actual costs as the project nears completion.
Class 3 estimate methodology is mixed, but contains somewhat detailed unit costs with assembly level (rather than an individual component level) line items. HD’s ability to add assemblies from libraries or historical data allows the estimator to efficiently and accurately build out a C3 estimate.
