There is broad recognition that recent investment levels in transportation infrastructure have been and remain inadequate. In addition, future funding levels are generally uncertain. As a result, the pressure on state departments of transportation (DOTs) to do more with less has never been greater, and agencies continue to actively pursue opportunities to lower costs while striving to maintain or even improve performance. In the maintenance arena, this has led an increasing number of state DOTs to consider the options of outsourcing and public-private partnership of some maintenance services. Cost is most often cited as a factor that must be considered when exploring such alternative delivery methods. To date, however, there has been no widely accepted process for determining the costs associated with performing highway maintenance if done entirely, or in large part, by the transportation agency itself. Furthermore, a review of any number of existing reports and audits that address the issue of in-house versus outsourced costs clearly demonstrates that often, some of the elements making up the total agency cost of an activity are not properly considered or, in some instances, are not included. |
