| Commissioning costs can vary considerably from project to project. Actual costs depend on the size and complexity of the project, and the extent and rigor of the commissioning specified.
There currently is no standard method of reporting the costs and savings associated with building commissioning. For many projects, commissioning costs were never separated from other project costs. For projects where these costs have been tracked separately, various methods have been used to report them.
The following table lists some of the most common methods. No matter which estimation method is used, however, commissioning accounts for a very small portion of overall construction and renovation budgets.
