AACE RP 19R-97 benchmarks the cost of preparing project cost estimates in process industries such as chemical, hydrocarbon, and utilities. It defines the estimating scope—from planning, quantification, costing, and risk analysis to documentation and review—while excluding design and project controls. Data from multiple sources show wide variation but consistent trends: estimating costs rise with project complexity and definition, yet decline as project size increases. Preparation costs typically range from 0.02% to 2% of total project cost depending on class and scale. The study introduces a parametric model linking preparation cost to project size, complexity, organization, and estimator productivity.
