Sydney Metro North West – Skytrain Proof Engineering

Sydney Metro North West is Australia’s largest public transport infrastructure project currently under construction and a high priority rail project for the New South Wales (NSW) Government.

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

Rendel, in association with ASPEC, was appointed by the ISJV as Proof Engineer to perform an independent design check of the viaduct as well as the cable-stayed bridge. Final certification was issued on 23rd October 2017. Services provided also included expert technical advice and value engineering for the cable-stayed bridge over Windsor Road at Rouse Hill, Sydney.

Scheduled to open in 2019, the Sydney Metro North West will be the country’s first fully automated rail system and is the first stage of Sydney’s new rapid transport network.
