What Is 3D Structural Steel Modeling?
3D structural steel modeling is the process of creating a detailed digital representation of a steel structure, including beams, columns, braces, plates, connections and other structural members. A coordinated 3D model provides project teams with a clear view of the structure before fabrication and installation begin.
CHAC United Technologies provides 3D structural steel modeling services that connect structural design, detailing, BIM coordination and fabrication requirements within a structured digital environment. Our models are developed to support accurate coordination, constructability review, fabrication planning, shop drawing development and steel erection.
From primary framing and secondary steel members to connection zones and interfaces, our modeling approach focuses on accurate geometry, coordinated project information and practical downstream deliverables.

Structural Model Development
Primary and secondary steel members are developed according to project drawings, specifications and modeling requirements.
Connection & Interface Coordination
Structural connections, interfaces and surrounding elements are reviewed within the coordinated model.
Multidiscipline Coordination
The structural model can be coordinated with architectural, MEP and other project disciplines to identify potential conflicts.
Fabrication & Erection Support
The coordinated model provides structured information that can support shop drawings, fabrication planning, material quantities and erection activities.
Our 3D Structural Steel Modeling Workflow
Every structural steel project has different design requirements, coordination conditions and fabrication needs. Our modeling workflow is structured to move project information from design intent toward a coordinated model that supports detailing, fabrication and construction.
