New roof above Central Station taking shape

New roof

The new roof above the future Northern Concourse is currently being installed at Central Station in Sydney.

The roof is part of the redevelopment of Central Station as the hub expands to serve Sydney Metro services from 2024.

NSW Minister for Transport Andrew Constance said the feature roof will provide light and shade.

“The 80-metre-long and 40-metre-wide roof extends from the northern end of Platform 8 to Platform 16 and will sit more than 16 metres above ground to enable natural light to filter into the station,” he said.

The structure was manufactured and pre-assembled in the Hunter Valley town of Kurri Kurri, with segments transported to Sydney. There are 58 cassette roof sections, known as hockey sticks for their shape, and each weigh about five tonnes. In addition, eight girders weighing 30 tonnes and up to 21 metres long are being installed.

The perforated aluminium cladding panels enable air to flow through the roof, and the design includes 21 diamond-shaped skylights with lighting and speakers.

The roof is expected to be completed by the end of the year, with Central Walk to be open to commuters in 2022.

To enable passengers to change between the future Metro lines, Sydney Trains services, light rail services and buses, Central Walk will extend from Chalmers Street, underneath current platforms and provide access to the Metro station, 30 metres underneath Central.

Excavation has reached 18 metres below ground and breakthrough into the tunnel box is expected in the coming months.

Laing O’Rouke won the $955 million construction contract with architecture firm Woods Bagot and John McAslan + Partners.
