Why a PPP?

Grimsey and Lewis (of the infrastructure definition) propose that the contemporary rise of PPPs as a means of delivering infrastructure projects stems from:

• Dissatisfaction with traditional procurement methods

• The development and maturing of the private finance model, and

• The adoption of "partnering", as a management process

Table 2 illustrates the relative number of infrastructure PPPs proposed across countries and shows the number of those projects that were funded and brought into service. The table includes the following types of infrastructure projects: roads, rail, water, and buildings.
