Project Cost Estimation

Project Cost Estimation, based on Wikipedia, is the approximation of the cost of project. The project cost estimate is the product of the project cost estimating process. The project cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate. An estimator is the professional who prepares cost estimates. There are different types of estimators, whose title may be preceded by a modifier, such as building estimator, or electrical estimator, or chief estimator. Other professional titles may also prepare estimates or contribute to estimates, such as quantity surveyors, cost engineers, etc. In the US, there were 185,400 cost estimators in 2010. There are around 75,000 professional quantity surveyors working in the UK.

The U.S. Government Accountability Office (GAO) defines a cost estimate as, “the summation of individual cost elements, using established methods and valid data, to estimate the future costs of a program, based on what is known today.” The GAO reports that “realistic cost estimating was imperative when making wise decisions in acquiring new systems.”

Project cost estimation is often needed to support evaluations of project feasibility or funding requirements in support of planning. A cost estimate is often used to establish a budget as the cost constraint for a project or operation.
