The purpose of this research, issued by the Australian National PPP Forum and carried out by the Melbourne Engineering Research Institute of the University of Melbourne, was to benchmark Australian PPP projects against a representative sample of traditionally procured projects on time and cost performance indicators. A total sample of 67 projects, of which 23 concerned transport projects, has been used for the benchmark. The report includes a review of earlier benchmarking studies. Some key findings of the study are:
- PPPs delivered projects for a price that is far closer to the expected cost than traditionally procured projects.
- PPP projects provide far great cost certainty.
- once PPP projects reach financial close there was only very little delay and changes were minimal.
