Because PPP is an innovative approach to project delivery, which can significantly reduce the timeframe of a project and introduce new technologies and other savings, public agencies may face cultural and political resistance to PPP. Resistance may be related to the processes employed by regulatory agencies or to the distinct world view of different project partners-from transit agencies to departments of transportation to freight railroads. Resistance may also be related to the influence of other project stakeholders, such as local governments, lenders, unions, and elected officials.
