The following criteria were used to select projects from the Phase 1 respondents for inclusion in Phase 2:
• A balance of project and program alliances.
• A mixture of NOP selection processes (non-price and price).
• Projects from road, water and rail sectors.
• A range of projects including those considered to perform well (time, cost, quality), and projects that did not perform well (refer to Appendix D).
• Projects from Victoria, New South Wales, Queensland, and Western Australia.
• Projects where detailed data was available.
• Projects where the alliance staff were available for interviews.
• Projects that were well progressed or completed.
• Projects that were either nominated by the Owner or indicated in Phase 1 they were willing to participate in Phase 2.
Applying these criteria to the 46 alliances identified in Phase 1, 14 projects were initially selected as detailed below:
• 5 road projects, 6 water projects, 3 rail.
• 2 projects from Western Australia, 2 from Victoria, 1 from New South Wales and 9 from Queensland.
• 12 project alliances, 2 program alliance.
• 12 alliances that selected NOPs using non-price competition, 2 that used outturn price competition.
The Research Team noted that some of these alliances were part of a broader project undertaken by the same Owner and after review it was determined that they were sufficiently independent (different objectives, different scope of work, different NOPs, different commercial frameworks, different selection processes etc.) that they could be considered as individual case studies for the purpose of this Study.
The selection of 14 projects was then compared to the population of projects40 which were identified as coming within the Study parameters to ensure that there was a representative collection of case studies. For example, 13% of the Phase 1 alliances were Western Australia based which compares reasonably with the two case studies from Western Australia selected (14% of 14). Similarly, 16% of project alliances involved price competition compared to the two case studies selected (14% of 14). The nine case studies in Queensland (64%) compares reasonably to the total population of projects in Phase 1 that occur in Queensland (45%). The one case study in New South Wales (which is somewhat less than the total population of 24%) reflects the availability of projects to the Research Team in that state.
