The purpose of the Capital Cost Database is not to prepare a detailed cost estimate. The Capital Cost Database should be used for preparing conceptual, “ballpark” estimates for conceptual projects or for better understanding the unique characteristics of a cost estimate by comparing the costs to historical experiences.
Further development of the Capital Cost Database is anticipated. More projects will be added to the database over time and an annual update of the inflationary factors is expected.
