    Steel Fabrication Drawing

    Workshop drawings for balustrades of Bridge#84 Dynon Road Walking & Cycling bridge, West Melbourne.

    The fabrication drawings for the 230-meter-long balustrade panels, which feature vibrant, rainbow-colored finishes were delivered with NIL mistakes and on time.

    Challenges in the As-Built Stage

    One of the most intriguing aspects of this project was the challenge posed by the as-built ramp slope and its curve, which deviated significantly from the original design coordinates. These deviations added a layer of complexity to detailing the balustrades, as each panel had to align perfectly with the precast kerbs.

    To address this, we worked closely with the builder and requested precise site measurements. These measurements were essential for us to adjust our detailing to account for the as-built ramp’s unique coordinates, ensuring every panel fit perfectly into place.

    Tailored Solutions for On-Site Realities

    The balustrade panels were fixed to the precast kerbs using as-built ferrules, demonstrating the adaptability required in projects where site conditions differ from the initial design. By leveraging the site measurements provided, we completed the detailing of all balustrades with precision, overcoming the complexities introduced by the ramp’s deviations.

    Conclusion:

    The Dynon Road Walking & Cycling Bridge is not just a pathway; it’s a vivid example of how meticulous detailing and innovative problem-solving can overcome challenges to deliver exceptional results. Its rainbow-colored balustrades are now a standout feature in West Melbourne, adding vibrancy and charm to the community.

    Addressing Design Discrepancies in Fixing Timber Wall to Steel Structures: An RFI Necessity

    When it comes to construction projects, precision and adherence to design specifications are critical. However, sometimes, practical considerations highlight the need for adjustments to those specifications. One such scenario involves the fixing of a timber wall to steel SHS columns and beams, where the original design calls for M12 bolts spaced 300 mm on centers.

    The Issue with 300 mm Spacing

    While the design specifies M12 bolts at 300 mm centers, this spacing is notably narrow for this type of application. Typically, such close spacing is reserved for situations where exceptional load-bearing capacity or additional structural support is required. In this context, a spacing of 600 mm on centers would be more than sufficient to secure the timber wall effectively, without compromising structural integrity.

    The concern with the 300 mm spacing is not just overengineering but also the practical implications on the job site. Implementing such close spacing requires more materials, labor, and time, leading to increased costs and potential delays. Moreover, drilling excessive holes into steel SHS columns for fixing purposes could weaken the structural integrity of the columns, which is an outcome that must be avoided.

    Alternative Solution: Gun-Fixing the Studs

    Given that the primary objective is to secure the timber wall to the steel structure, an alternative approach could be considered. Gun-fixing the timber studs directly onto the steel columns, without the need for drilled holes, is a viable option. This method is not only faster but also maintains the strength of the steel columns by avoiding unnecessary perforations.

    Raising the Issue: The Importance of an RFI

    Before proceeding with the job, it is essential to address this issue through a Request for Information (RFI). An RFI will formally document the concern regarding the overly narrow bolt spacing and propose the alternative method of gun-fixing. By raising an RFI, the project team can seek clarification and approval from the design engineers or the client to adjust the specifications accordingly.

    This step ensures that all parties are aligned, and any modifications to the original design are officially approved, reducing the risk of rework or disputes later in the project. It also demonstrates due diligence and a commitment to delivering a project that is both cost-effective and structurally sound.

    Conclusion

    In summary, while the original design calls for M12 bolts at 300 mm on centers to fix the timber wall to steel SHS columns and beams, this spacing is unnecessarily narrow. A 600 mm spacing would be sufficient, and an alternative method of gun-fixing the studs to the columns should be considered. Before commencing work, this issue must be addressed via an RFI to ensure that all stakeholders are in agreement and that the project proceeds smoothly and efficiently.

  • Managing Sticker-shock

    Managing Sticker-shock

    Author: RAJ (Arokiaraj Arputharaj)

    • The initial project was quoted at: $x
    • Changes were required on the project necessitating variations – at double the cost of the original quote!

    When this happens, it is ESSENTIAL that you call the client before you put in your variation documentation.

    Why?

    • The client will suffer from “sticker shock” after he sees your price.
    • “Sticker shock” means that the client will be so surprised, and shocked, that he will fall off his chair.
    • The client will lose trust in you.
    • The client will try to negotiate everything down.

    What should I do instead?

    • Call the client and say that the changes are huge.
    • Do not send variation documentation before addressing the “sticker shock issue”.
    • We cannot and do not negotiate on prices.
    • Going forward clients can choose between: (i) a fixed price quote – where we take on-board the risks of an infinite amount of variations, or (ii) where we charge variations but come in at a lower price.
    • Our variations are FIXED in price.
    • They are not negotiable.

  • Importance of Adhering to Standards in Modelling

    Importance of Adhering to Standards in Modelling

    In the realm of steel detailing, it’s not enough to simply follow design drawings and IFC models. As detailers, a thorough understanding of general standards is crucial to ensure accuracy and compliance.

    The Importance of Standards

    For instance, consider the Australian stair standards AS1657, which require a clear handrail area of 240° with a minimum clearance of 50mm. In the example below, the designer overlooked this standard, focusing solely on structural aspects without accounting for necessary clearances.

    Steel Detailing Standards

    Identifying and Addressing Errors

    As detailers, it is our responsibility to identify such discrepancies. In this case, the handrail does not meet the required clearance standards, which could lead to safety issues and non-compliance.

    When we encounter designs that do not meet standards, it’s essential to raise queries with the client. This proactive approach ensures:

    1. Compliance with Standards: Adhering to necessary safety and design standards.
    2. Cost and Time Efficiency: Preventing costly rework and project delays.
      Enhanced Quality: Ensuring the final product is safe, functional, and compliant.

  • Good Steel Fabrication Drawings : Simplifying Erection with Steel Columns at 14 Ridgeway AV Kew

    Good Steel Fabrication Drawings : Simplifying Erection with Steel Columns at 14 Ridgeway AV Kew

    Author: RAJ (Arokiaraj Arputharaj)

    Introduction

    Good fabrication drawings must consider erection feasibility. In this job during the design phase, we identified a potential erection issue involving the use of timber columns to support steel beams. Our proactive approach led us to recommend a change that would streamline the construction process and enhance the overall efficiency of the project.

    Project Overview

    The 14 Ridgeway AV Kew project involves the construction of a structure where two steel beams are supported by timber columns. This design posed a significant challenge: coordinating the efforts of two different types of erectors—one for steel and another for timber. This not only complicates the erection process but also introduces potential delays and additional costs.

    Identifying the Issue

    As steel detailers, our primary goal is to ensure that every aspect of the project is executed smoothly. We quickly realized that having two different erectors on-site to handle the steel beams and timber columns would create unnecessary complications. The need for precise coordination between the steel and timber erectors could lead to scheduling conflicts, increased labor costs, and potential delays in the project timeline.

    Proposed Solution: Steel Columns

    To mitigate these issues, we suggested replacing the timber columns with steel columns. This change offers several advantages:

    1. Streamlined Erection Process: With steel columns, a single erector can handle both the beams and the columns, simplifying coordination and reducing the risk of delays.
    2. Enhanced Structural Integrity: Steel columns provide better support for the steel beams, ensuring a more robust and reliable structure.
    3. Cost-Effective: By minimizing the need for multiple erectors, we can reduce labor costs and improve overall project efficiency.
    4. Consistency in Material: Using steel for both the beams and columns ensures uniformity in the materials, which can lead to better performance and durability over time.

    Client Approval and Implementation

    We presented our recommendation to the client, highlighting the benefits of using steel columns instead of timber. The client appreciated our foresight and agreed to the change. This decision not only simplified the erection process but also contributed to a more streamlined and cost-effective construction phase.

    Conclusion

    At 14 Ridgeway AV Kew, our proactive approach and attention to detail allowed us to foresee potential issues and implement effective solutions. By suggesting the use of steel columns, we ensured a smoother erection process and enhanced the overall quality of the project. At TEK1, we are dedicated to delivering excellence in steel detailing and construction, always putting our clients’ best interests at the forefront of our projects.

  • How We are helping our Client Save $100,000s on the Iconic “EMU IN THE SKY” Project

    How We are helping our Client Save $100,000s on the Iconic “EMU IN THE SKY” Project

    How we saved our 30% (i.e. hundreds of thousands of dollars) in Costs on the “Emu In the Sky” Project

    Recently, we have been detailing one of Australia’s most iconic projects, the “EMU IN THE SKY.” The structure of this project is a 30m globe,
    and as part of the steel detailing, numerous connections are involved.

    How did we do it?

    TEK1 has proposed

    • several solutions for the connections required.
    • proposed as easy way to acheive more accurate fabrication
    • Reduce Fabrication Time
    • and ultimately saved the client in the order of hundreds of thousands of dollars.

    Hexagon Joint Connections:

    The Problem

    • This design contains numbers of Hexagon join involved & it required six cruciform connections per hexagon joint. The weight of one Cruciform joint is 60-70kg approx

    The Solution

    • The TEK1 Team (Ramakrishnan)proposed an alternative solution that reduced the number of cruciform connections required for a hexagon joint..
    • By implementing our proposal, we eliminate two cruciform connection per hexagon joint, resulting in substantial savings N-numbers of connections in terms of fabrication.
    • This involves saving of Material cost & Fabrication cost.
    • Our client was very pleased to see these cost-saving proposals coming from the steel detailer.
    • Please refer to the following snaps which showing the detailed info about the proposal

    Cruciform Connection Accuracy

    The Problem

    Another example involves the cruciform design connection, where the initial design called for three 20mm thick plates to be welded
    together to form the joint. This connection demands high accuracy in fabrication, as all plates must be perfectly aligned at 90º to avoid
    significant erection issues. During welding, there is a possibility of distortion, making it difficult to maintain the desired shape.

    This is risky for the client – if they get it wrong they will lose: $abc and lose xyz months

    The Solution

    To address these challenges, TEK1 proposed a notched cruciform connection. Instead of three plates, we use only two plates, each with a
    notch. By interlocking the notched plates, we can avoid steel distortion and achieve the desired design shape more easily. This approach
    not only improves fabrication accuracy but also simplifies the assembly process.

    Again our client was very pleased to see these cost-saving proposals coming from the steel detailer & we implemented this in our current model.

    If you’re interested in having TEK1 manage your project, please send a quote request to our principal, Koshy, at koshy@tek1.com.au, and specify that you want Ramakrishnan to manage your project. We look forward to bringing our expertise to your next venture.
