Sydney Metro North West Rail Link

The A$8.3 billion (£4.6 billion) North West Rail Link was Australia's largest public transport infrastructure project at the time of construction and a high priority rail project for the New South Wales (NSW) Government.

The principal Design and Build (D&B) Contractor for the A$340m (£190m) Surface and Viaducts contract (SVC) is the Impregilo-Salini Joint Venture (ISJV). The SVC involved the construction of a 4.6km long 'Skytrain' section comprising a precast segmental elevated viaduct. The project also included a complex, 270m long cable-stayed bridge with a curved geometry in plan and employing a single plane of cable-stays.

Rendel was appointed by the ISJV as Proof Engineer to perform an independent design check of the viaduct as well as the cable-stayed bridge.

Rendel also provided expert technical advice and value engineering for the cable-stayed bridge over Windsor Road at Rouse Hill, Sydney.

Opened in 2019, the North West Rail Link is be the country's first fully automated rail system and is the first stage of Sydney's new rapid transport network.
