Cost Estimate Classification: Understanding Class 1–5 Estimates in Capital Projects
Cost estimate classification defines the maturity, methodology, and expected accuracy of project cost estimates. The AACE Class 1–5 framework links estimate types to project phases—from conceptual order-of-magnitude estimates to detailed definitive construction budgets.
