The Northern Portal ground engineering works on the West Gate Tunnel Project in Melbourne required a wide range of specialist foundation techniques to provide the client with a robust and economic solution to the challenges presented by the scope of foundation works required and the ground conditions encountered.
This paper looks at several of these challenges including highly congested reinforcement within secant piles, achieving tight pile verticality requirements and working with several foundation activities on a congested site, and the steps that the ground engineering joint venture took to ensure the works were completed to the satisfaction of the client.
