At CIMIC Group, our Integrated Digital Delivery strategy supports our operating companies to innovate and collaborate in priority areas where scalable solutions can make a significant difference to safety, operational performance and ESG outcomes.
For instance, with every new project CPB Contractors delivers, its projects are fully digitally enabled at every point in the delivery lifecycle; a requirement that EIC Activities and 1DCS regularly supports.
A recent example was the successful design of the temporary works supporting the tunnel boring machine (TBM) and back-up gantries for the Sydney Metro – Western Sydney Airport, Station Boxes and Tunnelling Works (WSA-SBT).
The project team engaged EIC Activities to lead the delivery of the design works, in collaboration with the 1DCS digital engineering team. EIC and 1DCS utilised CPB Contractors' common data environment which enables collaboration between project stakeholders through the use of BIM360 and Projectwise.
The team's designs were integrated with designs from other design delivery partners, including RBG, Geodata, BG&E and Arcadis in BIM360 and Projectwise.
Key to the project’s success is the utilisation of cutting-edge technologies and methodologies.
Leveraging BIM, the team digitally crafted representations of crucial components, including the thrust frame, thrust ring, thrust brackets, modules, segment feeder cradle, blind ring temporary supports, steel dolly and brackets.
This approach allowed the team to understand better the intricate interplay between the temporary works and the TBM; setting the stage for seamless integration and execution.
Precise 2D drawings extracted from the BIM model played a vital role in this project, providing detailed documentation essential for understanding and executing the erection of the temporary works on site.
By following this approach, we fostered seamless integration with the TBM, ultimately minimising delays and mitigating potential issues during construction.
Geoff Sewell, Managing Director of EIC Activities, said: "This collaboration between CPB Contractors, EIC and 1DCS has achieved remarkable goals, showcasing the diverse capabilities of the Group and successful teamwork between operating companies."
Brad Davey, Managing Director of Leighton Asia, said: “Strong collaboration has been the driving force behind this project. Facilitated by implementing BIM technology, we have created a platform that fosters seamless coordination among our team members even when sitting thousands of miles apart.
As a result, real-time visualisations and clash detection have become the norm, enhancing communication and reducing errors during the design and construction phases.
About the Sydney Metro – Western Sydney Airport, Stations Boxes and Tunnelling Works (WSA-SBT) Works
CIMIC Group’s CPB Contractors, in joint venture with Ghella, was selected by the NSW Government to deliver the Sydney Metro - WSA-SBT Works.
The new metro railway runs from St Marys through to the Western Sydney International (Nancy-Bird Walton) Airport and the Western Sydney Aerotropolis. It will provide a public transport service to the new airport and make a lasting economic contribution to Sydney’s west.
It involves the design and construction of 9.8 kilometres of twin tunnels and excavations for five stations at St Marys, Orchard Hills, Airport Business Park, Airport Terminal and Aerotropolis and services facilities at Bringelly and Claremont Meadows.
