Structural Steel Detailing

Steel detailing turns an engineer's structural design into the piece-by-piece documentation a fabrication shop actually builds from: shop drawings for individual members, connection and bolt detail, and erection drawings that sequence how the structure goes together on site.

We detail from structural engineering drawings, calculations or a coordinated 3D model, and can work in Tekla Structures or AutoCAD depending on your workflow and whether the project needs a full structural BIM model for coordination with other disciplines. The choice of platform is rarely arbitrary — a project running clash detection against services and architectural models genuinely benefits from a Tekla model, while a smaller standalone steel package may not need that overhead.

Material take-offs and bolt lists are produced alongside the drawing set, giving fabrication and procurement teams consistent quantities to work from, rather than a separate estimate that has to be reconciled against the drawings later.

Piece marking is treated as a first-class part of the detailing output, not an administrative afterthought. A consistent, logical piece-mark system makes the difference between a workshop floor that can track hundreds of individual members through cutting, drilling and welding without confusion, and one where two similarly-marked pieces get swapped and only discovered during erection.

Erection sequencing is coordinated with the fabrication programme where that information is available — there's little point detailing a perfectly correct structure if the drawing set doesn't reflect the order pieces actually need to arrive on site and go up, particularly on projects with limited laydown area or a tight crane schedule.

Connection detailing on a steel package is where fabrication cost is often won or lost. Two connections that satisfy the same engineering capacity can carry very different fabrication costs depending on how many welds, cuts and copes they require — we flag options where a simpler, equally compliant connection detail could reduce fabrication time, rather than defaulting to whichever detail happens to be first to hand.

For fabricators working across multiple simultaneous jobs, keeping piece mark numbering consistent across projects — rather than reusing the same mark scheme in a way that could cause confusion between concurrent jobs on the same shop floor — is a small detail that avoids a surprisingly common and easily preventable mix-up.
