PPPs have allowed all of the host nations to deliver specific projects sooner than possible with conventional project delivery methods. Essentially, the public sector's capacity to appropriate budgetary funds lags behind the private sector's ability to access capital in the financial markets, particularly for large-scale projects. Alone, this circumstance does not justify a PPP approach, but it is a fact that public agencies use to their advantage.
Several host nations claimed that PPPs produce better price and schedule certainty for design and construction. Certainly, one of the private partner's incentives is to open a project for service as quickly as possible so it can begin collecting revenue from tolls or government payments. As an illustration, table 10 shows the schedule performance of the PPP projects in New South Wales, Australia.
