SOLIDAL durability proves the perfect choice for facade upgrades on several Sydney Metro train station , Punchbowl, Campsie, Dulwhich Hill, Marrickville, for Aurecon and Laing O’Rourke.

Aurecon is completing detailed design for all civil, structural and building components of the new and upgraded rail infrastructure at Central Station, in partnership with GHD and Atkins.

As part of the broader transformation of Central Station, Aurecon was engaged by Sydney Metro and Transport for New South Wales to undertake comprehensive pedestrian modelling.

The scope includes:

Excavation and construction of the new underground Sydney Metro platforms at Central beneath platforms 13, 14 and 15

Central Walk – a 19-metre wide underground concourse from a new entrance on Chalmers Street
Escalators directly to suburban platforms 12 to 23 for the first time

An upgraded northern concourse with transformed pedestrian thoroughfares

A new feature roof to the Northern Concourse that will transform the space and emphasise the historic features of the Central Electric Building

Much of Central Station infrastructure dates back to 1906, with predecessor stations built at the site in 1855 and 1874. This project represents the largest upgrade to the site in decades.

It is also one of the first infrastructure projects delivered on such a scale in Australia to be fully digitised in terms of 3D modelling. Elements of the digital delivery include:

3D laser scanning and comprehensive data/asset management
creation of 3D models for design, construction planning and stakeholder engagement. Automation of processes, including clash detection and model management.

The project is particularly complex because of the extensive works taking place within a live station environment with more than 270,000 people using the station every day.

Early and enabling works for Central Station Metro have been underway since March 2018. Central Walk and the new escalators from Platforms 12 to 23 will be open in late 2022, with the new metro platforms to become operational once Sydney Metro City & Southwest services begin in 2024.
