Northwest Rapid Transit – SJV – UGL Limited and MTR Corporation.

The project
Sydney Metro Northwest is Australia’s largest public transport infrastructure project and will be the first fully automatic rapid transit rail system in Australia. The project involves the construction of 23km of new track between Epping and Rouse Hill – extending rail to north western Sydney. It also includes eight new stations – Cudgegong (open cut), Rouse Hill (elevated), Kellyville (elevated), Bella Vista (part underground/open cut), Norwest (underground), Showground (underground), Castle Hill (underground) and Cherrybrook (open cut).

The first 15km of the new rail section between Epping and Bella Vista will be in twin tunnels, with the tunnel portal at Bella Vista Station. This tunnel section of the project includes an open cut station at Cherrybrook and 3 new underground stations at Castle Hill, Showground and Norwest. One new rail section includes a 4km viaduct and 2 new elevated stations at Kellyville and Rouse Hill, and another includes 4 km at grade between an open cut station at Cudgegong and the depot, maintenance and stabling yard at Tallawong Road.

The project also consists of 13km of twin tunnels and underground stations in the existing Epping to Chatswood Rail Link (ECRL) where the following existing stations remain – Epping (underground shared with above ground Sydney Trains station), Macquarie University (underground), Macquarie Park (underground), North Ryde (underground), and Chatswood (above ground, shared platforms with Sydney Trains).

Our solution
As the Qualified Fire Engineer (QFE) for this project, Warringtonfire Sydney were responsible for the fire and life safety design of the Sydney Metro Northwest stations, tunnels, service facilities and viaducts. This involved extensive consultation with Transport for NSW, Metro Trains Sydney, Fire and Rescue NSW and local councils. We also had an ongoing role to monitor the construction phase and commissioning of the tunnel and stations for compliance with the fire safety engineering documentation we prepared.
