The purpose of this research is to benchmark Australian PPP projects against a representative sample of traditionally procured infrastructure projects on time and cost performance indicators. The research has been commissioned by the National PPP Forum and has been conducted in two phases. Phase 1 involved identification of a range of possible projects from around Australia that could be included in the research. Phase 1 forms the foundation for Phase 2. Some additional projects were added to the Phase 1 listing. Projects included in the data set were determined through a robust sampling process developed as part of the Phase I study; data for specific projects was provided by staff associated with the projects nominated from each jurisdiction and verified as appropriate.
