Under a conventional project-delivery method, ADOT finances both the design and construction of a transportation project. First, ADOT typically bids out and oversees the engineering design. Once the design is complete, ADOT then bids out and oversees the project's construction. Once the construction is complete, ADOT assumes the operations and maintenance of the facility. This process often results in change orders, which increase the cost of the project.

P3s make it possible to deliver much needed transportation projects in a timely manner, often years before the projects could be delivered using traditional project-delivery methods. Because P3s are business ventures for the private sector, the private sector has become efficient at delivering projects under this method. These efficiencies, combined with the private sector's resources, provide a more effective life-cycle cost and timely approach to delivering projects and provide a greater value for money for the public owner.
