PPPs can expedite the financing and delivery of transportation projects through the involvement of the private sector in these phases of a project, that lower project costs by avoiding inflationary cost increases, applying best practices and new technology, and transferring more technical and other risks to the private sector which is often better able to manage these risks. The private sector has an incentive to minimize construction delays in order to minimize costs and bring forward their revenue stream. Contract conditions including early completion bonus payments and the inclusion of the construction period within the concession period can provide further incentives to bring forward delivery.
