Retained costs are defined as costs incurred by the government in pursuing a project that are the same for both the traditional and the PPP options. For example, transition and move costs for a health care project are retained by the public sector as patients will have to be transitioned to the new facility regardless of the procurement model chosen. The cost of acquiring property for a transportation project is another example of a cost retained by the owner, as the price of the land along a particular alignment would be the same under both procurement options.
