This page show cases some of the Steel Detailing projectgs completed in Melbourne, Sydney, WA, Brisbane Tek1 has completed
Vent holes are required for draining molten zinc from the material being galvanised.
The size and location of the vent holes are important in achieving the vent holes.
Different sections have differnt vent hole position requirements.
Vent holes are not just of closed profiles like SHS.
UBs UCs PFCs etc require vent holes at base plates, cap plates, stiffner plates.
Also if two SHS comes together cut the wall out.
Please find attached drawings showing how much you need to allow for the turn buckle for future jobs
For 20mm Rod please allow 550mm
For 16mm Rod please allow 400mm
In addition to that please have one side of the solid rod either 500mm or 6000mm and the other side to make up to the required length.
In a residential project nestled in the scenic suburb of Scarborough, Bundeena, a critical coordination issue surfaced during the construction of the first-floor balcony. Originally designed to sit 100mm lower than the internal first-floor level (with the balcony at RL+33.000 and the floor level inside the residence at RL+33.100), the structural drawings, however, did not reflect this intended step-down.
Adding to the complexity, the vertical space between the first-floor Finished Floor Level (FFL) and the ground floor Ceiling Level (FCL) was only 300mm, while the structural floor members specified were 327mm deep. This created an unintended exposure of the first-floor framing—both below the ceiling and above the balcony floor.
Upon identifying the discrepancy, Tek1 promptly flagged the issue to both the structural engineer and the architect. A collaborative resolution was achieved by adjusting the levels: the internal FFL was raised to RL+33.253 and the balcony FFL to RL+33.153, restoring the 100mm step-down while maintaining all ground floor steel members at their original elevations. The level variation was managed by introducing floor joists of different depths—an efficient solution that avoided reworking the base structure.
Another issue surfaced in the form of a splice connection detail provided in the structural drawings. The original design called for splice plates on both the top and bottom flanges of the beam. However, the bottom plate posed a risk of clashing with the ceiling board. Tek1 proactively suggested an alternative splice configuration that avoided interference with the ceiling. This revised detail was reviewed and subsequently approved by the structural engineer.
This case serves as a strong example of how early-stage detection, open communication, and thoughtful coordination between teams can lead to efficient, buildable solutions—ensuring design intent is met without compromising on functionality or aesthetics.
What is HGD?
What is primer?
What is EPOXY?
You must follow the finish notes listed in Engineer and Architectural drawings.
If the steel is exposed to the elements, it will usually be specified as Hot Dip Galvanized (HDG). For interior structural steel, a primer coating is typically applied. And perhaps, where required, a top coat finish will be applied to make it look aesthetically pleasing.
What happens if you ignore or avoid finishes?
What is the lesson learned?
We are proud to be a part of the team in VSBA School-51 project.
Our detailing team worked closely with architects to ensure tolerances and offsets were met without compromising design intent With a limited fabrication and erection window, our detailing team adopted a fast-track workflow using Tekla Structures for 3D modeling.
This allowed us to provide early shop drawings for procurement and parallel review of sections still under coordination.
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 recently completed a cladding project for a prominent organization in Australia. The project involved detailing cladding and its support system around a footbridge with unique challenges.
The footbridge featured curved ends, but these were not simple linear curves, making the design and detailing process particularly intricate.
Tek1 conducted numerous meetings with the client and engineers to finalize the cladding’s shape and ensure it met both aesthetic and structural requirements. This collaborative approach ensured the project’s success.
Stay tuned for more projects from Tek1!

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
