The case study projects were selected by the participating jurisdictions on the basis that the projects were representative of their social infrastructure PPP projects. The projects sought were in the domains of health, education, justice or 'other'.20 For a project to included, it was necessary that:
• the PPP contracted services had been delivered for about three or more years of operations, and
• it was representative of the current style PPP contracts.21
The total number of PPPs meeting these criteria in the participating jurisdictions is 28 and the nominated case study sample was 12 projects, representing 43 per cent of the total. This was considered reasonable given that all four categories of projects were represented, and that the study required access to individuals with knowledge of a project during its operational life. The projects nominated and researched are listed in Appendix C, Table C.1.
