    Do not stick your neck out

    While detailing a project for a leading organization in Australia, the client asked us to calculate material quantities for production and procurement.

    However, this involves high risk.As detailers, we don’t control the nesting process — which depends on factors like sheet size, scrap management, and fabrication methods. Each fabricator uses different nesting techniques. If we provide material calculations without knowing their exact process, the numbers could be inaccurate.Any miscalculation could lead to over- or under-procurement, and the blame may fall on the detailer.

    Even if the client is willing to pay for it, detailers should avoid taking on such high-risk tasks. Stick to your scope and let the fabricator handle material estimation based on their own nesting and production methods.

  • Media wall

    Media wall

    TEK1 recently completed a media wall support project for a prominent organization in Australia. The goal was to provide detailed support steelwork for a large media wall screen — with a unique challenge.

    Unlike most projects, we didn’t receive any structural design drawings. Instead, we were given only a concept design, leaving it to TEK1 to determine suitable steel profiles and connection details.

    Our team carefully studied the concept and nominated appropriate profiles for each connection based on feasibility, strength, and ease of fabrication. Once the detailing was complete, we submitted it to the structural engineer for review.

    The engineer approved our detailing with minimal changes, which helped speed up the process and made things easier for the client. The use of different profile types also optimized the design for practicality and efficiency.

  • 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.

  • Steel to precast connections (Ferrule)

    Steel to precast connections (Ferrule)

    Steel detailers play a crucial role in ensuring that connections between precast & steel are both practical and efficient. In this blog, I’ll share my experience with the challenges I faced in steel-to-precast connections.

    Design

    The design specified two ferrules on both sides of a precast wall. However, following this design may leads to clash between the ferrules.


    The Proposed Solution

    To address this, I suggested using a CHS (Circular Hollow Section) conduit. This approach would allow a single bolt to be used for both sides of the connection, ensuring proper alignment .(Providing ferrules at a different location will not be feasible as we do not have sufficient edge distance)


    The Outcome

    The structural engineer approved the proposal but recommended an alternative solution: double-ended ferrules. The query is now with the builder to decide which method suits their construction process best.

    Key Takeaways

    • Understanding Precast Connections: Detailers should be aware of connection requirements and potential issues like concrete cover.
    • Collaboration is Key: Engaging with engineers and builders ensures practical solutions are implemented.
    • Flexibility Matters: Proposing alternatives opens the door to more efficient and cost-effective outcomes.

  • Peatsferry Bridge barriers

    Peatsferry Bridge barriers


    Tek1 recently completed a barrier replacement project for a renowned organization in Australia. This project, located near Sydney, involved replacing existing barriers with new ones, and it came with its unique challenges.

    The task was to detail a new 536-meter-long barrier while ensuring the anchor holes for the new posts did not clash with the existing steel posts.

    Aligning anchor holes without clashes presented difficulties in maintaining consistent linear post distances. This required precise planning and coordination.

    Through multiple meetings with the client, we finalized the post locations that balanced structural integrity with practicality. This approach ensured the barrier was installed seamlessly without disrupting the existing infrastructure.


    The result was a well-executed barrier replacement, meeting the client’s expectations and delivering a durable solution.

  • EMU IN THE SKY:Branches

    EMU IN THE SKY:Branches

    Continuing from our previous blog on the EMU IN THE SKY project, this post delves into the challenges and solutions for positioning the branches into the globe structure.

    Challenges with the Original Design

    The initial structural design, while visually impressive, posed significant challenges during the erection phase. The lack of tolerance in positioning the branches made the process more complicated, increasing the risk of errors and time-consuming adjustments.

    EMU team proposal

    To overcome this, the team introduced:

    Circular Plates with Holes: A circular plate with pre-drilled holes was introduced, allowing for precise alignment of the branches.

    Slotted Holes in the Outer Stub: Slotted holes were added to the outer stub welded to the globe. This innovation offers adjustable positioning, making the assembly process significantly easier and more efficient

    In this method we can place the branches plate in any rotation.

    Why This Design is Feasible

    The updated design not only simplifies the erection process but also reduces the likelihood of rework. The added tolerances ensure that branches can be positioned accurately with minimal effort, saving both time and resources.

    Stay tuned for more updates on the EMU IN THE SKY project as we continue to share insights and innovations from this iconic endeavor.

  • Expert Steel Detailer looks beyond Structural Drawings

    Expert Steel Detailer looks beyond Structural Drawings

    Expert Detailing | Sydeny | Melbourne

    This blog focuses on a crucial aspect of detailing: collaborating with fabricators and understanding steel profiles.

    Structural engineers typically specify steel profiles based on their calculations. However, as detailers, we need to consider two critical factors:

    Product Availability: Is the specified material readily available in the market?

    Fabrication Feasibility: Can the profile be easily fabricated?

    Balancing these factors can save significant time and effort for both fabricators and detailers.

    Real-World Example

    In one case, an engineer specified a curved SHS (Square Hollow Section) beam.

    While this profile met the structural requirements, bending an SHS beam is a challenging process .There are fabrication limitations. Instead, we suggested using two PFCs (Parallel Flange Channels), which are much easier to bend.

    Before making the change, we sought the engineer’s approval, and they confirmed the modification. By doing so:

    • We avoided delays in fabrication.
    • We ensured the project stayed on schedule.

    Why This Matters

    If we had followed the original design without questioning it, the fabricator would have requested changes due to the difficulty of bending an SHS beam. This would have caused delays and disrupted the project timeline.
