East Link Planning and design challenges • Availability or resources • Engineering (Design and Construction) • Plant • Materials • Coordination of design • 3 major consultants • Consistency and high quality • External stakeholders

East Link Specific issues associated with PPP model • Performance spec vs detailed spec • Maximise traffic volumes • Programme pressure • Tolling issues • Whole of Life costs

Peninsula Link Strategic Context

East Link

Conclusion • PPPs have been around for about 20 years are evolving • PPPs are a popular way to deliver major Transport Infrastructure and becoming more so • Most of the challenges in planning, designing and constructing major transport projects occur irrespective of procurement model • With PPPs, WLC and operational considerations are built into the design more effectively
