The concrete industry has had a major part to play in the design and construction of the Westgate Tunnel project with many developments and learnings. In this presentation, we will explore the technical challenges being addressed, opportunities for innovation, proposed construction methodologies and provide a construction update. With design 75% complete, construction well underway and the Southern Hemisphere’s largest tunnel boring machine having recently arrived in Melbourne, this is an exciting time to hear the latest about this once-in-a-career project. Book soon to learn how this incredibly large, complex and challenging project is unfolding.
