TEK1, we recently had the opportunity to detail GRC panel brackets for a section of the Sydney Metro Tunnel, utilizing a point cloud survey to ensure precise alignment and installation.
Project Overview
The client provided a point cloud survey of the tunnel, allowing us to accurately determine the placement of GRC panels and their supporting brackets. Since tunnel walls are rarely perfectly straight—often featuring irregularities, ups, and downs—extra attention was required to ensure each bracket was positioned correctly for a seamless fit.
Challenges & Solutions
Efficient Coordination – By leveraging point cloud technology, we minimized potential site adjustments, streamlining the installation process for our client.
As-Built Adjustments – The natural deviations in the tunnel wall’s shape meant that standard placements wouldn’t work. The point cloud data helped us fine-tune the bracket positions to match real-world conditions.
Precision Detailing – Each steel bracket was meticulously detailed to accommodate the GRC panels, ensuring a secure and uniform installation.
Conclusion
Working with as-built tunnel walls requires high accuracy and adaptability, and this project was a great example of how TEK1 effectively integrates advanced technologies like point cloud surveys into our detailing process.
