Cross River Rail is a 10.2km rail line between Dutton Park and Bowen Hills, which includes a 5.9km twin tunnel under the Brisbane River and Brisbane CBD. The project also includes construction of four new high-capacity underground stations at Boggo Road, Woolloongabba, Albert Street, Roma Street and redevelopment of the existing over Dutton Park Station. Cross River Rail will integrate with proposed Brisbane Metro services. The Tunnel, Stations and Development Package will primarily deliver the underground section of the project. The scope of work will include:
- The tunnel from a southern portal near Dutton Park station, under the Brisbane River and the CBD, to a northern portal beyond Normanby
- Four new underground stations at Boggo Road, Woolloongabba, Albert Street and Roma Street
- The tunnel portals and dive structures
- All associated mechanical, electrical and safety systems, including vertical transportation for passengers at underground stations
- Tunnel track work, traction power systems and selection rail operation and control infrastructure. Refer to the map below for a project overview.
- Four new underground stations at Boggo Road, Woolloongabba, Albert Street and Roma Street:
- Underground Primary Structures
- Platform & cavern structures
- Above ground and canopy structures
- Underground station ancillary structures
- Dutton Park Station Upgrade
- New pedestrian bridge to access new platforms
- Design of new Station Building
- Extension and re-configuration of existing island and side platforms.
- North & South Portal Structures
- Transition of new CRR lines form above ground to below ground
- Dive structures transition from open trough with cantilevered retaining walls to a complete cut and cover tunnel interfacing with the CRR bored tunnel at the North entry and Boggo Rd station at the South.
- Boggo Rd Station to PA Hospital Cable Stayed Pedestrian Bridge
- Cable stayed bridge crossing the QLD Rail corridor
- Cable stayed section of the bridge is approximately 102 metres long with a total deck width of 7.0 metres.
- Bridge consists of two spans, a western span of 36 metres and an eastern span of 66 metres.
- Underpinning design for Southern Freight Flyover Bridge
- Design of underpinning beam and load transfer to support existing freight flyover bridge to facilitate the new Southern dive structure underneath.
Construction Engineering / Temporary Works
- Initial Retention Design for four new underground stations at Boggo Road, Woolloongabba, Albert Street (3 shafts) and Roma Street (3 shafts).
- Combination of anchored soldier piles and shotcrete infill panels to facilitate open box construction (with the exception of Albert St Station) to a maximum depth of ??m.
- Design of temporary shoring props Albert St station Lots 1 and 3.
- Miscellaneous temporary works design across CRR project
Civil Engineering / Site Establishment
- Civil engineering design to facilitate construction site establishment
- Survey and structural Analysis of all buildings and infrastructure adjacent to the new station precincts to estimate effects of the construction works associated with the new CRR.
Lessons Learnt / Value
- RBG’s value to the CRR project is our unique ‘design for delivery’ approach utilizing:
- Our skills and capability in structural engineering
- Our experience in underground rail infrastructure projects in Sydney and London.
- Our valuable experience in construction engineering and temporary works and working with contractors
- Our extensive local experience and knowledge of the Brisbane construction market and the station sites.
