Structural Steel Detailing Services: What is it all about?

Looking deeper than our last post about steel detailing, let’s learn more about this specialist drafting service. As covered previously, steel detailers translate engineering drawings into a form that can be interpreted by a fabricator. From there, the service generates sets of layout instructions, which are then used to assemble and erect complex structural frameworks. Now, with the generalities out of the way, let’s add some meat to this barebones description.

Determining the Structural Erection Heirarchy

Think of the architect of a project as the person who does all the facework. This highly qualified individual designs a structure out of steel beams and plating. Next, the engineer makes the building strong and safe. The size of the beams and their load-bearing properties are conceptualized. For the final set of drawings, the steel detailer uses sets of common practices and building regulations to dimensionally thrash out a steel construct’s real-world form. It’s still not enough, though, this level of generalization. What we need is some specifics, which can then be used to describe this discipline much more precisely.

Structural Steel Detailing: The Methodical Approach

So the service calls in 3D computer drafting software and advanced simulations. The engineering professional creates CNC data points, bills of materials, welding and fastening sites, anchor bolt plans, and doesn’t stop the day’s work until a work schedule has been agreed upon. From here, the annotations are dropped into the framework drawings. They mark out the dimensions, from one terminating beam end to the other. Additionally, marked on that same beam, drilling notations, weld planes and cut lines are assigned. Think about the level of precision required to get the drawing work done. From one side, the steel detailer dimensionally outlines every beam edge and corner, plus every junction and connector. For the other half of the job, this same individual marks out not only the weld locations, in great detail, but also the types of welds, the fastener and connector preferences, and the erection markings, as determined by the initial engineering drawings.

The basics have been covered, and we’ve even moved deeper down into a steel detailer’s mind. This is a translator of engineering blueprints. Indeed, steel detailers create bridges between engineers and fabricators. They transform design drawings into fabrication-pertinent schematics, which contain erection markings, cut lines, bolt holes and weld points. Done today in proprietary 3D software packages, a budding professional still starts with the tools of the trade. Working in an office, a computer will come into play at some point. First, though, there’s a drafting board and a large piece of blueprinting paper waiting.
