26 Public Works Professional July-August 2013 Home to Australia's rst Grand Prix in 1928 and now a venue for world-class motorcycle and V8 Supercar events, picturesque Phillip Island Circuit stirs deep emotions among motor sport fans. So any heavy construction on its hallowed ground calls for careful planning and almost surgical precision. This was foremost in the minds of Phillip Island Operations (who manage the circuit for owners Linfox) when they realised last year that a new wear surface was needed. They knew that in 1988 Downer had played a key role in a major upgrade when the circuit was widened to 10m with signi cant asphalt correction work performed to iron out bumps prior to a full-width overlay. The work proved so resilient that Downer was summoned back 10 years later, in 1998, purely to overlay a circuit that had endured the stress of racing, testing and practising for roughly 300 days each year. That overlay stood the test of time for 14 long years. But last year, when it was realised a new surface was needed, Downer SMOOTH & FAST ASPHALTING EXPERTISE MEETS NEED FOR SPEED was given 10 months notice in February to start planning for a new overlay in December. However, that early heads-up carried a clear mandate -- Phillip Island Operations and Linfox wanted the "best race track in the world". THE HARD YARDS That was a tough order to meet, because Phillip Island was already considered one of the world's best motorcycle circuits, holding the title to the fastest average lap speeds in the world. But what ensued over the next 10 months was a classic example of how early contractor involvement (ECI) can pay o when de ning a scope of works, and providing budgetary pricing, constructability assessment and process optimisation. To determine the most cost-e ective project delivery methods, Downer met regularly with the Linfox team and Aurecon, which had also been appointed to the project. "Our main objective was to completely replace the existing surface with an asphalt mix of similar look and texture, without altering the geometry of the track," says Mark Taylor, Downer Infrastructure's Melbourne Metro Manager. "But as the job progressed, the scope became more detailed and called for close interaction between all parties. "The ECI model got that interaction o to a good start, under the catch-cry of 'best for track'. It was a simple phrase but it worked very powerfully in bringing all parties together," he says. Downer recently resurfaced Phillip Island Circuit for a third time in 24 years, making the world's fastest motorcycle track even faster. It's a great example of how early contractor involvement delivers big benefts.
