Suburban Rail Loop – Burwood Tunnel Access Shaft

Cerecon played a key role in delivering essential temporary works solutions for the Burwood Tunnel Access Shaft, a critical component of the Suburban Rail Loop (SRL). The project required innovative structural engineering expertise to support the safe and efficient installation of the ground retention system, ensuring the stability and integrity of the shaft throughout construction.

Our scope

• Shade structure modularisation – turning the shade structure into a fully modular design to provide safe and efficient on-site protection, improving constructability while maintaining flexibility across project phases.
• Thermal expansion and contraction assessment – engineering advice on the potential impact of temperature variations on the retention system, supporting the client in discussions with other project stakeholders.
• Centre of gravity assessment – detailed analysis of critical structural elements to optimise handling and installation safety. Cerecon developed Grasshopper scripts to automate these assessments, reducing turnaround times for lifting assessments.
• SPMT installation design with limited headroom – a specialised Self-Propelled Modular Transporter installation process for the Level S3 structure, enabling precise and efficient movement of large steel components.
• Lashing design for transportation – secure lashing configurations for the safe and compliant transport of heavy structural components to site.
• Strut support design – robust support systems for the retention struts, ensuring stability and safe load transfer during installation and operation.
• Client advisory and installation support – on-site technical support to address installation challenges, tolerance compliance and constructability improvements.

Cerecon’s involvement in this project underscores its expertise in complex temporary works design, combining advanced engineering methodologies with practical construction solutions to enhance safety, efficiency and precision on major infrastructure projects.
