  • How TEK1 Solved the Complicated Star Node Puzzle in Great EMU in the Sky

    How TEK1 Solved the Complicated Star Node Puzzle in Great EMU in the Sky

    At TEK1, we believe great detailing is more than just precision—it’s about understanding real-world challenges and turning complexity into clarity.

    The Challenge

    The Great EMU in the Sky project presented one of the most unique and technically demanding structures we’ve ever worked on—a 30-metre-wide globe made up of 128 intricate “star nodes” connecting the bracing members.

    These nodes weren’t ordinary joints. Each featured 5 or 6 connection points and came in three different CHS sizes, with every arm set at unique, non-repeating angles.

    For the fabrication team, this posed a significant challenge:

    • 128 Complex Star Nodes, each with custom angles
    • Inconsistent geometries
    • Time-consuming and difficult to fabricate accurately

    Even with precise 3D modelling, the practicality of fabrication was proving to be a serious bottleneck. Something had to change.

    The Turning Point

    That’s when TEK1 took the initiative.

    Rather than simply delivering a model and walking away, we engaged directly with the fabricator to understand the issue from their perspective. We realized that even the most accurate detailing wasn’t enough—what the team needed was smarter, fabrication-friendly solutions.

    The Solution

    Our detailing team re-engineered how the star nodes were documented, presented, and ultimately fabricated. Key solutions included:

    • Custom fabrication jig design: We developed a dedicated jig that allowed star nodes to be fabricated with greater ease and precision, regardless of the angle configuration.
    • Standardized node sub-groups: We grouped similar nodes together to reduce variation and streamline production.
    • Detailed templates: For common angle types, we provided accurate templates to guide fabrication.
    • Visual fabrication aids: Clear drawings showing exact cuts, welds, and orientations for every node.

    The Result

    • Faster fabrication times
    • 🎯 Improved accuracy and alignment
    • 🔁 Reduced rework and error rates
    • 🤝 Stronger collaboration between design and workshop teams

    Most importantly, the fabricators were able to work with confidence, knowing each node would come together exactly as intended.

    Taking Detailing to the Next Level

    This project reinforced one of TEK1’s core values: true excellence in detailing comes not just from precision—but from empathy. When we truly understand the needs of the people building the structure, we unlock practical, buildable solutions.

    The Great EMU in the Sky is more than a globe—it’s a powerful example of what happens when detailers and fabricators work together as one team.

  • TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 3

    TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 3

    We hope you found our previous two blogs on the Sydney Metro project insightful. If you missed them, check them out using the link below!

    In this blog, we’ll share about a connection detail that we proposed to the engineer.

    As per the design, a PFC beam needed to be supported by an I-beam above. However, in one location, the PFC beam was offset from the I-beam — and no connection detail was provided for this condition in the design drawings.

    To address this, TEK1 proposed adding tab plates to connect the offset PFC beam securely. This solution maintained structural intent while resolving the missing detail.

    The structural engineer reviewed our proposal and accepted it.See the below response from the engineer ‘Option shown in snap-03 accepted to maintain 2 bolts at each connection. Additional tab plate to be 80×10 FPBW to PFC. Bolt spacing to follow 140 gauge line of flange of SB14.

    We go beyond drawings to ensure constructibility, reduce rework, and keep projects moving forward.Stay with TEK1 for more updates on steel detailing challenges and solutions in our upcoming blogs.

    SYDNEY METRO CITY & SOUTHWEST TUNNELGRC PANELS & ITS BRACKET

    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.

  • TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 1

    TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 1

    TEK1 is currently engaged in steel detailing for the Sydney Metro project, working with a reputed organization in Australia. During the detailing process, we have encountered several design challenges. Here, we will share one such issue and how we resolved it.

    The Issue

    A design required two unequal angles welded to a small hanger with 10mm packer plates. This left insufficient weld space, making fabrication tough.

    Recognizing this issue early, we raised a query with the concerned team. Our initial proposal was to cut both angles to create the required weld space.

    After reviewing our concern, the team suggested an alternative solution that involved reducing the packer plate thickness from 10mm to 4mm. This adjustment allowed for a 6mm weld clearance on both sides without significantly affecting the design.

    If this issue had gone unnoticed and we had followed the original design, it would have caused complications for both the fabricator and the designer. By identifying the problem early and addressing it proactively, we saved time and costs for the client.
