A New Addition to Launceston Christian School, Tasmania
Let’s dive into the exciting expansion at Launceston Christian School in Tasmania—a thoughtfully designed new building covering an area of 1,440 square meters. This structure adds essential facilities to the campus, including classrooms, an auditorium, a storage room, and a library.
Challenges:
A key engineering challenge in this project was related to the cast-in base plates. These base plates had to be finalized and fabricated before the slab pour could begin. This required us to release accurate base plate fabrication drawings and exact location details early in the project timeline.
Since altering column positions later would not be feasible—especially if rafter alignments or other components demanded changes—we had to finalize all column locations at the earliest stage. This meant that the column modeling had to be both precise and quick.
Once the column layout was locked in, the modeling of the beams and girts progressed smoothly without any complications.
This project serves as a great example of how early coordination, clarity in design, and proactive decision-making contribute to successful structural outcomes.

TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 4
We hope you found our previous blogs on the Sydney Metro project insightful. If you missed them, check them out.
In this blog, I’d like to share another connection detail we proposed to the structural engineer on the Sydney Metro project
Since this is a metro project, fireproofing sheets are required on steel members as per the structural engineer’s specifications. However, the original connection details provided by the engineer were not feasible interms of installation of fireproofing sheets — they would make installing the fireproofing sheets difficult and time-consuming.
Please see the connection details below. These are the standard connection details typically used for the steel members.
However, applying these as-is may create difficulties during the installation of the fireproofing sheets.
We identified this issue early in the detailing stage and proposed alternate connection details that would allow easier installation of the fireproofing sheets without compromising the structural requirement.
The engineer reviewed our proposal, suggested a few adjustments like thickness changes, and then approved our updated connection details.
Catching these issues early during detailing avoids major headaches later for installers and saves valuable time on-site

TYPES OF MODEL VIEWERS FORMAT , PURPOSE AND ITS BENFITS
A. IFC Mode
Industry Foundation Classes (IFC) is an open file format developed by Building Smart Alliance. It is an international data exchange standard for exchanging building information across different software platforms. An IFC Model is just a model of a building or a construction project with all geometric, structural, and semantic information.
Key Features of IFC Models:
- Open Standard: IFC is vendor-independent, i.e., any software that supports it can be accessed, without regard for the vendor.
- Static Data Exchange: It is mostly utilized for data exchange between software tools, data import, and export. For instance, an architect can create a model using Revit and export it as an IFC file, which can then be imported into structural engineering software like Tekla or SAP2000.
- Limitation of Real-Time Coordination: IFC files are representations of the model at a specific moment. Changes in one application are not duplicated in another except where the file is re-exported and re-imported.
- Use Cases:
- Exchange of models between stakeholders with various software.
- Ensuring interoperability in interdisciplinary projects (e.g., construction, engineering, and architecture).
Advantages of IFC Models:
- Encourages collaboration and interoperability in BIM workflows.
- Reduces errors by making sure all stakeholders are working from the same information.
- Allows clash detection and coordination between different disciplines.
B. Live Link Model Viewer
A Live Link Model Viewer is software that enables real-time sharing and visualization of BIM models on various software platforms. Unlike IFC models, which are pre-exported static files, a Live Link Model Viewer enables multiple users to work on the same model at the same time using different software programs. Common examples of Live Link Model Viewers are:
Revit Live: A cloud-based collaboration platform by Autodesk.
Trimble Connect: A BIM data management and sharing tool.
Key Features of Live Link Model Viewers:
- Real-Time Collaboration: One software application’s changes are reflected immediately in the model viewer and other linked applications.
- Dynamic Data Sharing: Unlike static IFC files, Live Link Model Viewers offer dynamic, real-time linking between software applications.
- Multi-User Collaboration: Multiple stakeholders can view and edit one model at the same time even though they are in different software.
- Use Cases:
- Real-time collaboration among architects, engineers, and contractors.
- Collaborative design review and clash detection.
- Smooth communication between teams working on different software platforms.
Advantages of Live Link Model Viewer Benefits:
- Make collaboration more effective and faster.
- Eliminate the need for repeated file imports and exports.
- Enhance accuracy by getting the entire team to work on the current version of the model.

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
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.
Check out the snapshots below to see how the GRC panels are securely fixed to the tunnel wall using custom steel brackets.
