Connecting Western Sydney Airport to Greater Sydney with a new 23km metro line

Project Overview

This 23 km metro rail line will connect Western Sydney Airport to Greater Sydney, linking new and existing residential areas via six new stations, including Bradfield Metro Station.
The Stations, Systems, Trains, Operations and Maintenance (SSTOM) package spans seven precincts and includes stations, service buildings, a stabling yard, and a maintenance facility, forming a critical piece of the region’s future transport network.

Scope of Work

TTW’s façade and structural engineering teams were engaged to design and document façade systems across all stations. The scope covered:

  • External glazed and aluminium façades, structural steel, precast elements, and internal cladding and ceiling systems.
  • The team also delivered specialised design elements, including perforated screens, mesh systems, skylights, and blast-resistant façade solutions, balancing safety, durability, and the visual identity and resilience of the transport network’s built environment
  • Building on the tender phase, TTW continues to support the project through detailed design and construction, collaborating with subcontractors to deliver IFC documentation and certification.
  • A true integrated approach between Structural and Façade Engineering Teams was required to deliver the façade and façade steel for these stations to the requirements of Sydney Metro and the project consortium, working together in a single BIM Model with 1:1 REVIT Façade and Steel Documentation to IFC.
