The analog method of cost estimation

After clarifying the similarities between the old and new projects, the method consists in estimating the cost of the new project based on criteria characteristic of the old projects, known as influential parameters (scope, volume, mass, etc.). This approach can be used as a feasibility study in the upstream phase of projects (APS or APD) to measure a good return on investment.

This fact sheet will first give you an overview of the different cost estimation methods, illustrated by three tools, and then show you in more detail how to carry out an analog estimate. This method provides orders of magnitude with an uncertainty of the order of x%, enabling you to make a "Go/No Go" decision on the follow-up to a call for tenders or a planned investment.
