Software stack

We pick the platform to fit the geometry, the fabricator, and the downstream analysis pipeline — never the other way around.

SolidWorks

Parametric solid modeling for equipment skids, custom fixtures, brackets, and weldments. Sheet-metal, weldment, and surface environments with full GD&T (ASME Y14.5) and Toolbox standard hardware. Used for tight-tolerance machined and welded assemblies.

  • Top-down weldment assemblies with cut-list and BOM
  • ASME Y14.5 GD&T on detail drawings
  • Sheet-metal flat patterns for laser/waterjet/plasma cutting
Tekla Structures

BIM-grade structural steel detailing for pipe racks, equipment platforms, mezzanines, and seismic bracing systems. Connection design, full clash detection, and IFC export for coordination with mechanical, electrical, and piping models.

  • AISC 360-22 connections (CIDECT, CISC, BCSA modules)
  • CNC NC1 / DSTV output for fabrication shop machinery
  • IFC 4 / NWD export for BIM coordination
AutoCAD

Industry-standard 2D fabrication shop drawings — base plate plans, member elevations, bracing layouts, weld and bolt details, and erection drawings. AWS A2.4 weld symbols, AISC detailing conventions, and ANSI title blocks ready for fabricator and AHJ review.

  • AWS A2.4 weld symbols and AISC bolt callouts
  • Layered drawings (S-, M-, E-) for trade coordination
  • PDF, DWG, and DXF deliverables
Inventor / Revit / NX (on request)

Project requirements drive software selection. We also model in Autodesk Inventor for OEM equipment, Revit for architectural-coordinated MEP supports, and Siemens NX for advanced freeform geometry feeding directly into ANSYS Workbench.

  • Inventor weldments and iLogic configurators
  • Revit families for MEP support coordination
  • STEP / IGES / Parasolid neutral-format exchange

From 3D model to fabrication

A single coordinated dataset drives the 3D assembly, BIM coordination model, and 2D shop drawings — eliminating inconsistencies between design intent and shipped steel.

Drawing types we produce

Every package is structured around AISC 303-22 Code of Standard Practice and the fabricator's preferred shop conventions.

General Arrangement (GA)

Plan, elevation, and section views establishing overall geometry, member sizes, grid lines, and elevations. The reference document for all downstream details.

Erection Drawings

Field assembly drawings showing piece marks, bolt patterns, splice locations, and erection sequence. Coordinated with the structural engineer's loading and bracing requirements.

Shop / Fabrication Detail Drawings

Single-piece details with cut lengths, hole patterns, bevels, weld preparation, and AWS-compliant weld symbols. Each piece tagged with a unique mark number tied to the BOM.

Anchor Bolt Setting Plans

Anchor layout, projection, embedment, and tolerance plans coordinated with concrete rebar drawings. Includes ACI 318-19 Ch. 17 anchorage forces and template details.

Connection Details

Moment, braced, shear, and base-plate connections designed per AISC 360-22 and AISC Manual 16th edition. CBFEM verification (IDEA StatiCa) on demand for non-prequalified geometries.

Seismic Bracing Layouts

Trapeze, transverse, and longitudinal bracing for piping, ductwork, conduit, and cable tray per ASCE 7-22 §13 and OSHPD OSP/OPM. Pre-approval drawings ready for AHJ review.
