  • TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 2

    TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 2

    In the last blog in Sydney metro project , we discussed about the design issue regarding angle weld. https://www.tek1.com.au/steel-detailing/tek1s-steel-detailing-for-sydney-metro-resolving-design-challenges-1/

    Here we are going to discuss about the member placement issue.

    The design specified two PFCs on both sides of a column.Column was surrounded by fireproofing sheets. However, the PFC flanges clashed with the fireproofing sheets, making installation difficult. Additionally, the bolts connecting the PFCs would interfere with the fireproofing.

    To resolve this, TEK1 planned a simple yet effective adjustment—changing the orientation of the PFCs. This allowed for seamless fireproofing installation without compromising the structural integrity.

    If we have followed the design , then the erection team will have difficulties to provide the fireproofing sheets.By identifying and addressing potential clashes early in the detailing process, TEK1 saved significant time and costs for the client, ensuring a smooth execution on-site.

  • Erection Issue Eliminated Through Suggested Changes in the Splice Connection During Detail Engineering

    Erection Issue Eliminated Through Suggested Changes in the Splice Connection During Detail Engineering

    Issue Identified During Detail Engineering

    • During detail engineering, it was identified that the design specifies both-side web plates, with shop weld on one side and field bolts on the other.
    • This would have created a field erection issue, as the shop-welded web plate on both sides prevents secondary beam placement.

    Proposed Solution: Fully Bolted Connection

    • Use bolted connections on both sides instead of welding one side.
    • This allows the web plate to be shipped loose, making field installation easier.
    • At the site, the secondary beam can be placed first, followed by the web plate installation and bolting.
    • Factory-drilled holes ensure precise alignment and better quality.
    • Eliminates on-site welding hazards and inspection issues.

    Client Approval

    • The client accepted the suggestion due to its practical benefits and ease of installation.
    • The change improves efficiency, cost-effectiveness, and safety.

    Conclusion

    • Switching from welded-bolted to fully bolted improves constructability.
    • Ensures stronger, safer, and more efficient structural connections.
    • Small design changes can greatly impact project success.

    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.

  • Melbourne Airport Gantry

    Melbourne Airport Gantry

    At Melbourne Airport, a gantry supporting a signboard spans 26 meters between laced columns without intermediate supports. The box gantry alone weighs 8 tonne. Since the gantry would bend because of to its self weight, pre-camber of 170mm was provided at the middle.


    For accurate representation, two models were created: one with pre-camber for assembly drawings and another without for general arrangement (GA) drawings. This approach ensures clarity in fabrication and erection, maintaining structural integrity while achieving the desired final alignment.

    Input information was an Inventor model and pdf drawings

    We have extracted the information from inventor, cross checked with pdf drawings, Checked constructurability, Resolved design details so that items can be fabricated at lowest cost.

    These chutes were submitted for approval, and was approved without any issues.

    Eventhough these chutes are for grain transfer, mining projects have similar requirements.

    KAMAY FERRY-LA PEROUSE WHARF

    This was a complex project, but we successfully delivered it. Our scope included the balustrade around the bridge, which needed to be provided in multiple panels. By utilizing advanced modeling techniques, we were able to complete it within a significantly shorter timeline.

    Since the structure is above the sea, we provided several cost-saving ideas for both erection and fabrication to optimize the process.

  • Transforming 3D CAD Models into 2D Fabrication Drawings: The Orange Rope Project

    Transforming 3D CAD Models into 2D Fabrication Drawings: The Orange Rope Project

    Imagine trying to build a complex 3D structure using only flat, 2D puzzle pieces—every cut, weld, and alignment must be perfect. That’s exactly the challenge we faced with the Orange Rope project, where 3D CAD models had to be transformed into precise 2D fabrication drawings. How did we tackle this engineering puzzle? Let’s dive in!

    The “Orange Rope” is a series of rolled pipes placed between the piers in a bridge. This project involves a total of 11 ropes, with the following images showcasing a sample of a rope.

    Challenges and Solutions

    1. Converting 3D Models to 2D Fabrication Drawings

    The initial input received was in the form of 3D CAD drawings, while the required output consisted of 2D drawings for fabrication. To achieve this, the 3D ropes were broken down into a series of 2D pipe members, which were then welded together to recreate the 3D structure. Each rope was divided into 4 to 5 assemblies, each containing multiple 2D pipes that, when assembled, would form the final 3D shape.

    2. Welding and Alignment

    Welding each 2D pipe in the correct position to form the 3D structure presented a significant challenge. With intricate dimensions, aligning each pipe manually would be nearly impossible. To tackle this issue, a splice system was introduced. This system involved a welded plate with a nut affixed at the bottom of one pipe and a corresponding hole in the adjacent pipe. By bolting the pipes together through these holes, proper alignment was ensured before welding. Once the pipes were secured and welded, the bolts were removed, and the holes were plug-welded for a seamless finish.

    3. Asymmetrical Cuts for Base Plate Fixing

    Another major challenge was the presence of asymmetrical cuts in the pipes for fixing them onto the base plates. To ensure precise cuts, unwrapped views of the pipes were provided. These unwrapped views were printed on paper at a 1:1 scale and then wrapped around the pipe. This method allowed for accurate cutting directly from the template, ensuring proper fitment and alignment during installation.
