  • Bridging for Curved Roof

    Will Hook Lok Work

    Short answer – No.

    What are the options

    • Bolted ends with S Channel
    • Bolted ends with Tapered Washers

    Bolted Ends with Swivelling brackets

    Will need 2 bolts on each end. To stabilize, will need 2 tek scres on each bracket holding it to s channel

    P Type with tapered washer.

    Again bolted edge because with tapered washer the hooks will not go over the purlin. Hence tapered washer and bolted ends, or spacer washers to make up with bolted ends.

  • When to Provide HDG for Structural Steel

    We should have a clear understanding of when HDG (Hot-Dip Galvanizing) is required for structural steel.

    If the structural notes state that “exposed steel shall be treated with HDG,” then HDG should be provided for steel that is exposed to weather.

    However, if the steel is located inside the building and is not exposed to weather, it should not be considered exposed steel. In such cases, the steel should be treated with primer or paint, as specified in the structural notes.

    By correctly understanding the project specifications and applying the appropriate surface treatment, we can avoid unnecessary HDG costs. This will help us optimize the project cost and provide a cost-effective solution while meeting the client’s requirements.

  • T4-Airport lounge upgrade

    T4-Airport lounge upgrade

    TEK1 completed a Airport lounge upgrade project for reputed organization in Australia. Our primary scope was to provide shop drawings for lounge renovation steel.

    This project required close coordination with site measurements as it involved an existing building. A significant amount of as-built information was required to ensure the steelwork was accurately detailed to suit the existing conditions.

    Our team carefully coordinated the site measurements and as-built information throughout the project. Despite the complexity and the number of existing conditions involved, the coordination was completed smoothly, and we successfully delivered the project without errors or rework.

  • Bend Lines and Fabrication: What Detailers Should Know

    Bend Lines and Fabrication: What Detailers Should Know

    As steel detailers, we must have a good understanding of fabrication methods and how our drawings will be used in the workshop.

    When providing bent plate DXF files, we include the bend lines. The fabricator uses these lines as etching marks to identify where the plate needs to be bent.

    However, the bending direction is important. If the plate is bent upwards from the etched side, there is generally no issue. But if it is bent downwards from the etched side, there may be a risk of cracking along the etched line.

    When providing bent plate DXF files, always check the bending direction and make sure the plate is intended to be bent upwards from the etched side.

  • RHS/SHS Material Grade – Client Alert for Grade 450

    Client must be informed of NON-STANDARD Grades.

    In many projects, RHS/SHS members are commonly supplied in Grade 350. However, if the structural design specifically requires Grade 450, this must be identified and brought to the client’s attention at the MTO or detailing stage.

    Why we have to identify the Grade 450?

    Grade 450 is a higher-strength material compared with Grade 350. The higher material grade can also affect the material availability, procurement cost and project quotation.

    Therefore, Grade 450 requirement identified early can help the client account for the correct material cost in the quotation and procurement stage.

  • A Practical Guide for Australian Steel Projects

    A Practical Guide for Australian Steel Projects

    This article provides an overview of the important Australian Standards for steel detailing and serves as a practical guide for steel detailing projects in Australia.

    Australian steel detailing requires more than accurately modelling beams, columns, plates and connections.

    In addition, a professional steel detailer needs to understand the project documentation and the applicable Australian Standards.These standards provide an important technical framework for structural steelwork, fabrication, erection and access systems.

    However, standards should always be considered together with the project’s structural drawings, specifications, contract documents and other requirements.

    Therefore, understanding the applicable standards is an important part of producing accurate, coordinated and practical steel detailing documentation.

    In particular, For steel detailing projects, several standards are particularly important, including AS 4100, AS/NZS 3678, AS/NZS 3679.1, AS/NZS 1163, AS/NZS 5131, AS 1657 and AS 1428.1:2021.

    1. AS 4100 – Steel Structures

    AS 4100 – Steel Structures is one of the primary standards used for structural steelwork in Australia. The current edition is AS 4100:2020.

    Furthermore, standards Australia describes AS 4100:2020 as an important standard for the Australian steel sector and identifies it alongside AS/NZS 5131 as key guidance for structural steelwork.

    In particular, AS 4100 is particularly important when interpreting structural design information.

    Therefore, a detailer does not normally perform the structural engineer’s design, but needs to understand the design requirements sufficiently to produce accurate fabrication and erection documentation.

    Typical detailing considerations include:

    In addition, the structural engineer’s drawings and specifications remain the primary design inputs.

    Finally, the detailer’s responsibility is to accurately translate those requirements into constructible steelwork.

    2. AS/NZS 3678 – Structural Steel: Hot-Rolled Plates

    AS/NZS 3678 covers structural steel, including hot-rolled plates, floorplates and slabs.

    Furthermore, standards Australia identifies it as one of the key structural steel standards published as part of its steel-sector standards work program.

    In particular, This standard is important when specifying and detailing fabricated steel components such as:

    When preparing shop drawings, the steel grade specified by the engineer should be clearly identified.

    In addition, the detailer should also ensure that the material description used in the drawings and MTO corresponds with the project requirements.

    For example, a plate shown as a particular grade on the structural drawings should not be changed to another grade simply because the alternative material is readily available.

    3. AS/NZS 3679.1 – Hot-Rolled Bars and Sections

    Australian steel projects commonly use hot-rolled sections such as universal beams, universal columns and angles.

    AS/NZS 3679.1 – Structural steel, Part 1: Hot-rolled bars and sections is therefore highly relevant to steel detailing.

    During modelling and detailing, the detailer should verify:

    Furthermore, accurate member identification is especially important in Tekla Structures because incorrect profiles or grades can flow through to fabrication drawings, NC files, MTO reports and material schedules.

    4. AS/NZS 1163 – Cold-Formed Structural Steel Hollow Sections

    Hollow sections are widely used in Australian construction for columns, beams, frames, handrails, balustrades and miscellaneous steelwork.

    In particular, AS/NZS 1163 covers cold-formed structural steel hollow sections.

    Common hollow-section profiles include:

    • SHS – Square Hollow Sections
    • RHS – Rectangular Hollow Sections
    • CHS – Circular Hollow Sections

    During the detailing process, it is important to correctly represent the section size and wall thickness specified by the engineer.

    For example, an SHS column specified as SHS150 × 6 should not be modelled as SHS150 × 9 unless the change has been formally approved.

    Furthermore, this is particularly important when steel members are connected to windows, doors, precast elements, concrete walls or architectural features where dimensional clearances are critical.

    5. AS/NZS 5131 – Fabrication and Erection of Structural Steelwork

    One of the most important standards for the fabrication and erection stage is AS/NZS 5131 – Structural steelwork – Fabrication and erection.

    Furthermore, standards Australia explains that AS/NZS 5131 covers areas including fabrication, bolting and welding, surface preparation, corrosion protection, painting, galvanizing, site erection and modification of steelwork.

    In particular, this standard is particularly relevant to the information shown on shop drawings.

    Therefore, A professional steel detailer should consider fabrication and erection requirements when producing drawings, including:

    Fabrication

    Firstly, Drawings should provide sufficient information for the fabricator to manufacture the component correctly.

    This may include:

    Erection

    In addition, Steelwork must also be practical to assemble on site.

    Detailers should consider:

    However, a connection that looks acceptable on a computer model may still be difficult or impossible to install on site.

    Therefore, Good detailing requires an understanding of both fabrication and erection.

    6. AS 1657 – Fixed Platforms, Walkways, Stairways and Ladders

    AS 1657 is particularly important for industrial steelwork, access platforms, stairs, ladders, walkways and handrails.

    The standard addresses fixed means of access and safe working areas, including platforms, walkways, stairways and fixed ladders.

    For steel detailers, this can affect many components, including:

    When detailing stairs and handrails, the detailer must carefully check the project requirements and applicable standard requirements rather than relying on assumptions from previous projects.

    Important items to verify include:

    The architectural drawings, structural drawings, specifications and project requirements should all be coordinated before finalising the detailing.

    7. AS 1428.1:2021 – Design for Access and Mobility

    AS 1428.1:2021 provides design requirements for access and mobility in new building work. In particular, it covers requirements that can affect accessible paths, ramps, stairs, landings, handrails, circulation spaces and other accessibility-related elements.

    For steel detailers, this standard can be relevant when detailing commercial building stairs, ramps, handrails, balustrades, platforms and other steelwork that forms part of an accessible path of travel.

    During the detailing process, the architectural and engineering drawings should be checked carefully for accessibility requirements. For example, dimensions, clearances, handrail arrangements, ramp and landing requirements may need to be coordinated with the structural steelwork.

    In addition, the detailer should coordinate the steelwork with architectural layouts and project specifications to avoid conflicts with doors, walls, finishes and other building elements.

    However, the steel detailer should not independently determine accessibility compliance. Instead, the applicable project requirements, architectural documentation, NCC requirements and relevant engineering information should be followed.

    Therefore, where AS 1428.1:2021 applies to the project, its requirements should be considered during the steel detailing and coordination process.

    8. AS/NZS 5131 and the Importance of Steel Detailing

    Australian steel detailing is closely connected to fabrication and erection.

    Before finalising the steelwork, several practical questions should be considered:

    These questions can prevent costly fabrication changes and site modifications.

    AS/NZS 5131 provides a framework for fabrication and erection practices, making coordination between engineering, detailing, fabrication and erection particularly important.

    9. Australian Standards and Tekla Structures

    Modern steel detailing is often completed using 3D modelling software such as Tekla Structures.

    However, software does not automatically guarantee compliance with Australian Standards.

    For this reason, The detailer still needs to interpret the project documentation and apply the correct requirements.

    10. Coordination Between Architectural and Structural Drawings

    One of the most common challenges in Australian steel detailing is the difference between architectural and structural information.

    Typical discrepancies include:

    Therefore, the steel detailer should identify these discrepancies during the checking stage.

    An effective RFI should clearly state:

    As a result, this approach reduces assumptions and helps maintain a clear record of design decisions.

    11. MTO and Material Identification

    Australian steel detailing is not complete when the 3D model is finished.

    In addition, The model must also produce accurate fabrication information and material quantities.

    The MTO/BOM should correctly identify:

    However, incorrect modelling can result in incorrect MTO quantities and fabrication information.Therefore, model checking should be performed before issuing the final material report.

    12. Common Steel Detailing Mistakes

    Some common problems encountered in Australian steel detailing include:

    Incorrect steel grade

    Incorrect member size

    Missing connection information

    Poor bolt access

    Architectural conflicts

    Missing site information

    Unapproved design changes

    13. The Role of a Professional Australian Steel Detailer

    A professional steel detailer acts as an important link between engineering design and steel fabrication.

    Therefore, the role involves much more than simply drawing steel members.

    For this reason, A competent detailer should be able to:

    Conclusion

    Australian steel detailing requires a combination of technical knowledge, practical fabrication experience, attention to detail and understanding of Australian Standards.

    In Particularly the Standards such as AS 4100, AS/NZS 3678, AS/NZS 3679.1, AS/NZS 1163, AS/NZS 5131, AS 1657 and AS 1428.1:2021 provide important references for different aspects of structural steelwork.

    However, standards should not be viewed in isolation.

    Therefore, The successful steel projects depend on coordination between the structural engineer, architect, steel detailer, fabricator and erector.

    The goal of professional steel detailing is simple:

    Create accurate, clear and buildable steelwork information that can be safely fabricated, delivered and erected on site.

    Finally, for current editions and official information, always refer to the applicable project specifications and the official Standards Australia catalogue rather than relying on outdated or unofficial copies of standards.
