Project Delivery—PPP Concession Periods
Public-Private Partnerships (PPPs, P3s) and related concessional delivery methods have current popularity in the delivery of infrastructure across the world, but have been used in different disguises for several centuries. A defining characteristic of a PPP is a concession period, agreed between the two main parties—a public authority and a private concessionaire. The concession period is the time given to the concessionaire to design and construct the infrastructure and collect revenue, before handing back the infrastructure to the authority.
