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
Peninsula Link
Project Benefits • Up to 40 minutes travel time savings in peak periods • Ease congestion on existing roads • Bypass eight sets of traffic lights, six major roundabouts and a rail crossing • Completion of missing link • Road safety • New Shared Use Path
PenLink– Project Description • 27 kilometres of freeway standard road • Two traffic lanes in each direction • On and off ramps to 11 roads including three freeway to freeway connections • 28 bridges (45 separate structures) • Three million cubic metres of earthworks • Around 1.5 million trees and plants requiring 80,000 cubic metres of mulch • 25 kilometre shared walking and cycling path • High standard urban design, environmental management and community information
Procurement Model Availability PPP What is an Availability PPP? • 1st of its kind in Australia • Toll free – payment based on lane availability and a series of KPI’s • $759 million fully underwritten (debt and equity) • Concession period – Delivery (D&C) + 25 years

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
