PPP is regarded as a method for procuring and delivering both public assets (new assets or upgrades of existing assets) and public services.
This section will propose a broad definition of PPPs to capture the sense of the PPP concept as a means to procure assets, procure and deliver services, and manage existing infrastructure. It will also provide a narrower definition, the main definition to be used in the rest of the PPP Guide, which focuses on PPPs as an alternative way to procure new infrastructure.
After introducing the PPP definition, and qualifying general aspects surrounding the PPP term, this section will summarize the main features of a PPP contract.
On the basis of the proposed definition and PPP contract structure, the next section will provide further detail, describing the main types of contracts and other contexts in which the private sector plays a role in public infrastructure management and services.
Further information about the PPP concept will be provided in subsequent sections. These sections will explain how different names and concepts are used to refer to PPP contracts in different jurisdictions, which type of projects and/or sectors are typically suited to PPPs, and what a typical PPP structure looks like.
