Cross River Rail Case Study

Cross River Rail

Overview

Cross River Rail is a 10.2 kilometre rail line between Dutton Park and Bowen Hills which includes 5.9 kilometres of twin tunnels under the Brisbane River and the CBD. The project also includes four new underground stations at Boggo Road, Woolloongabba, Albert Street, and Roma Street, as well as station upgrades for the Dutton Park station and the Exhibition station. Engaged by CBGU D&C JV, Willow’s bid role offered digital engineering services. Our team undertook model federation, model coordination of all contributing consultants and provided support or the construction team in construction sequencing, tem porary works and 4D requirements.

Scope of work

WillowDigital™ Engineering has been engaged to

  • Design delivery – Existing conditions 3D models generation and implementation into the design and construction coordination process, cloud-based design coordination, models requirement definition and assessment to suit the Digital Twin development

  • Finalise design & modelling – Turning Project Information Model (PIM) into Asset Information Model (AIM): Postconstruction update of the design models (when required) to ensure alignment of the simultaneous design and construction phase works and mitigate site issues, ensuring all the data produced during construction is captured and collated into the design models

  • Progressive digital handover – Provide handover support services including models and data review, models auditing and data validation

    The Willow advantage

    Cross River Rail has derived the following benefits

    • Experience the highest coordination between designers and existing conditions thanks to high quality modelling recreated from site feature survey, historical drawings and point-cloud survey. These models are the basis for a precise 3D design development and a fully-coordination design process.
    • Reduced risk and improved certainty of the program providing 4D analysis
    • Reduced on-site surprises by providing accurate digital coordination from day one
    • Asset Operation in mind since early design stages to derisk the design-construction-handover-maintenance process and reduce re-works and loss of information
