Abstract:
The Lane Cove Tunnel Project in New South Wales is one of the major transport projects in Australia in recent times and an important link in the high class motorway network of the Sydney orbital. As an example of the continuing influence in the transport infrastructure, this paper describes the use of concrete construction to provide an effective solution for one of the two major ventilation stations for the project, and meet the design challenges of tight site constraints, staged construction program, acoustic and vibration attenuation, and maintenance and operational requirements. The innovative use of concrete construction for the multilevel structure incorporating a deep beam transfer system spanning over 20m and supporting equipment floors, an upper car-park level, and the ventilation stack over a 35m deep vertical excavated-shaft, played a significant role in providing a workable economical solution for the ventilation station and enabled staged construction and early installation of ventilation equipment.
