Guide to Structural Steel Detailing with Tekla

In the world of steel fabrication, success is measured in millimetres and minutes. Every beam, plate, and connection must fit perfectly, and every hour spent on rework or clarifying confusing drawings is an hour of lost profit. The bridge between an engineer’s design and a flawlessly executed structure is structural steel detailing. When done correctly, it is the engine of workshop productivity. When done poorly, it is a source of endless frustration.

At Proline Structural Detailing, we have built our reputation on providing a service that gives our clients optimal workflow and maximum productivity. A critical tool in achieving this is Tekla Structures. This guide explains how we use Tekla to translate complex designs into clear, buildable information that empowers your workshop and keeps your projects on track.

What is Tekla Structures and Why Does it Matter?

Tekla Structures is more than just drawing software; it is a powerful Building Information Modelling (BIM) platform designed specifically for the construction industry. Developed by Trimble, it allows us to create a highly detailed and data-rich 3D model of a steel structure. This is not just a visual representation. It is an intelligent digital twin of the final building, containing every piece of information needed for fabrication and erection.

For a fabricator, this means moving away from ambiguous 2D plans and into a world of absolute clarity. Instead of interpreting lines on paper, you receive a complete fabrication package derived from a single, accurate source. This is the foundation of modern, efficient steel construction.

The Core Features of Tekla That Drive Workshop Efficiency

Tekla Structures is packed with features, but we focus on those that deliver tangible benefits to our steel fabrication clients. It is about using the technology to solve real-world problems on the workshop floor and on site.

Intelligent 3D Modelling

The heart of Tekla is its ability to create a constructible 3D model. We model every single component, from the largest universal beam to the smallest bolt. This isn’t just for looks. The model behaves like a real structure, allowing us to test connections, check for access, and visualise the entire erection sequence. It is the ultimate tool for buildability reviews.

Automated Clash Detection

One of the most significant risks in any construction project is clashes, where different elements (like steelwork and pipework) are designed to occupy the same space. Finding these issues on site is a nightmare of delays and costly modifications. Tekla’s automated clash detection allows us to identify and resolve these problems in the digital model, long before a single piece of steel is cut. This single feature saves our clients thousands of pounds in rework.

Parametric Connection Design

Tekla includes a vast library of intelligent, parametric connections. This means we can apply standard or custom joints to the model, and the software automatically creates the necessary plates, bolts, and welds according to predefined rules. If a beam size changes, the connection updates automatically. This speeds up the detailing process immensely and ensures consistency across the project.

Seamless Drawing Generation

From the approved 3D model, we can generate a complete set of drawings automatically. This includes:

  • General Arrangement (GA) Drawings: For site installation teams.
  • Assembly Drawings: Showing how individual pieces are welded together.
  • Single Part Drawings: For cutting and drilling individual plates and profiles.

Because all drawings are linked to the central model, any changes made to the model are reflected across the entire drawing set. This eliminates the risk of outdated or contradictory information, a common problem with traditional 2D workflows.

Direct CNC Data Output

To maximise workshop automation, Tekla produces machine-readable data files (like NC1/DSTV) directly from the model. This information can be sent straight to your CNC saws, drills, and profilers, ensuring parts are fabricated with complete accuracy and minimal manual input. This direct line from model to machine is a cornerstone of efficient production.

The Proline Workflow: Using Tekla to Deliver Certainty

A powerful tool is only effective in the right hands. Our process is designed to leverage Tekla’s capabilities to provide a streamlined, collaborative, and transparent service.

  1. Project Assessment and 3D Model Creation: The process begins with a thorough review of the engineer’s and architect’s drawings. We then build the initial 3D model in Tekla, flagging any technical queries or discrepancies early. This is where we lay the foundation for a successful project.
  2. Coordination and Clash Resolution: With the model built, we run clash detection and coordinate with other trades. Any issues are raised, discussed, and resolved within the digital environment. We issue the model for review and hold collaborative meetings to ensure all stakeholders are aligned.
  3. Drawing Approval and Fabrication Release: Once the model is approved, we generate the full fabrication package. This includes the GA drawings, which are issued for your final approval. Once we receive “Status A” approval, we release the complete set of workshop drawings, lists, and CNC data.
  4. Ongoing Support: Our service does not stop once the drawings are issued. We remain on hand to support your workshop and site teams throughout the project. If an unexpected site condition arises, we can quickly adapt the model and re-issue updated information, keeping delays to an absolute minimum.

Tangible Benefits for Your Fabrication Business

Adopting a Tekla-driven workflow with Proline translates directly into improved profitability and reduced risk for your business.

Drastically Reduced Rework

By identifying clashes and confirming buildability in the 3D model, the steel that arrives on site fits the first time. This eliminates the need for expensive and time-consuming site modifications, keeping your erection teams productive and your project on schedule.

Increased Workshop Throughput

Clear, accurate assembly drawings and direct CNC data output mean your fabricators can work with confidence and speed. There is less time spent interpreting drawings or manually correcting errors. This increases your workshop’s capacity and allows you to take on more work.

Accurate Material Procurement

Tekla automatically generates precise material lists and bolt lists directly from the approved model. This allows you to order exactly what you need, reducing material waste from over-ordering and avoiding delays caused by shortages. It brings a new level of control to your procurement process.

Enhanced Collaboration and Communication

The 3D model becomes the single source of truth for the project. It provides a clear, unambiguous reference point for architects, engineers, fabricators, and erectors. Using tools like Trimble Connect, all stakeholders can view the model, ask questions, and track progress, leading to better-informed decisions and fewer misunderstandings.

Building a Stronger Reputation

Delivering projects on time, on budget, and without issues enhances your reputation in the industry. By partnering with a detailer who uses Tekla effectively, you are demonstrating a commitment to quality, efficiency, and modern construction methods. This is how strong relationships are built and repeat business is won.

At Proline Structural Detailing, we are invested in the success of our clients. We use Tekla Structures not just as a drawing tool, but as a project management and quality assurance platform. Our experience in this industry allows us to provide the practical guidance and high-quality information you need to thrive.

If you are ready to experience the certainty and efficiency that a model-based workflow can bring to your business, we are ready to help.
