Structural steel detailing

Steel That Fits the First Time, at Any Tonnage

On large programs, one detailing error repeats across hundreds of pieces. Senior detailers check every member and connection, so steel erects on schedule.

Where margin leaks

Every Misfit Costs Your Margin

Steel sits on the critical path. One detailing error repeats on every floor, paid for in refabrication.

  • Field Misfits

    Where margin leaks
    Holes, plates and lengths that miss by fractions of an inch stop erection and burn crane hours.
    What we fix
    Every member and connection checked in a coordinated 3D model, so erection keeps moving.

  • Refabrication

    Where margin leaks
    Wrong copes, holes or lengths send steel back to the shop, and you pay for it twice.
    What we fix
    Shop drawings to AISC 303, AWS D1.1 and AS/NZS 5131, so steel is cut and welded once.

  • Trade Clashes

    Where margin leaks
    Steel that clashes with MEP and architecture forces field cutting and rework.
    What we fix
    Clashes resolved with every trade in the model before release, so nothing is cut on site.

  • Approval Bottlenecks

    Where margin leaks
    Slow submittals and RFI loops leave the shop idle and push the steel schedule.
    What we fix
    Phased releases and fast RFI turnaround that keep the shop loaded.

What clients ask first

Structural Steel Detailing: Common Questions

Straight answers from our engineering team. If your question isn’t here, ask us directly.

Ask a senior engineer An engineer replies within one business day.
What does your structural steel detailing include?

Coordinated 3D steel models, assembly and single-part shop drawings, erection drawings, anchor bolt plans, DSTV / NC1 CNC files and bills of material, produced in Tekla Structures, SDS2 or Advance Steel to your shop standards.

Which codes do you follow, and who is responsible for the design?

AISC 360, AISC 303, AWS D1.1 and RCSC for US projects; AS 4100, AS/NZS 5131 and AS/NZS 1554 for Australian projects. Design responsibility stays with your engineer of record, who reviews and seals the work. Bimgraphix does not stamp drawings; we answer for every sheet matching your design inputs, and any gap is raised as an RFI, never guessed.

How do you make sure drawings are right before they reach our shop?

Every package is modeled and clash-checked in 3D, checked by an independent checker, then reviewed by a senior detailer before release. Approval comments are tracked to closure, so nothing reaches the shop floor unresolved.

How are fees and schedules set, and can you handle large programs?

Fees and delivery dates are fixed in a written proposal from your scope, priced per ton or per package, before any work starts. Large programs are released in phases by area, sequence or erection order, with the team sized to your schedule. Revision rounds are agreed up front, and anything outside scope is quoted before we do it.

How do you protect our drawings, models and data?

We sign your NDA before any files are shared. Your models, drawings and CNC files remain your property, exchanged through Trimble Connect, Autodesk Construction Cloud, Procore or a secure link, and access is limited to the team on your project.
