Full project details
The completion of the Chatswood Transport Interchange in early 2009 was the culmination of more than three years’ work to redevelop one of Sydney’s busiest transport hubs. The project was undertaken by one of the largest public–private partnerships in New South Wales at the time, with Laing O’Rourke engaged as the design and construct contractor.
Chatswood Transport Interchange serves more than 35,000 rail passengers every day, as well as the thousands of bus passengers and pedestrians using the station as a thoroughfare. Projected growth is estimated to reach more than 50,000 commuters by 2021, and the redevelopment was therefore essential to cater for this future growth.
This multi-faceted engineering and building project involved designing and constructing both a temporary and a new railway station. The new station comprises twin island platforms and a commuter concourse, bridgeworks, a new bus interchange, taxi ranks, kiss-and-ride facilities, a basement car park, 10,000m2 of convenience-based retail, and rail trackwork to accommodate the new Epping–Chatswood Rail Link. The project also provided for the future construction of three residential towers over the interchange.
The major works were carried out within a bustling commuter environment. Maintaining rail, bus and pedestrian access—and constructing within metres of live rail lines—presented challenges that required innovation and flexibility in construction techniques. Complex staging was also required, including multi-phase, top-down construction.
Laing O'Rourke contributed a unique multidisciplinary capability to the project and extensive experience in civil, rail and building works. The team developed an alternative design focusing on the urban grid, which improved the quality and rate of construction while minimising community and stakeholder impacts. The project also incorporated an Australian-first railway track solution to resolve several structural, acoustic and spatial design concerns.
Laing O’Rourke successfully completed this project with no unscheduled effects on train operations. Today, the infrastructure forms an integral component of the Epping–Chatswood Rail Link.
