Structural Building Information Modeling

A Coordinated Digital Structure for Design, Documentation and Construction Information

Structural BIM organizes the geometry and project information for foundations, columns, beams, slabs, walls, structural steel, reinforcement, embeds and related structural components within a controlled three-dimensional model.

Structural Drafting Group supports engineering consultants, architects, contractors, fabricators and BIM teams with Revit structural models, steel and concrete modeling, model-based drawings, parametric families, clash review, quantity outputs and coordinated revision support.

A structural BIM model communicates approved engineering information; it does not automatically perform or approve structural design. Analysis, calculations, member sizing, reinforcement design, connection capacity, stability and professional certification remain with the qualified and authorised engineers identified by the contract.

Structural Engineering versus Structural BIM

Professional Design Decisions and Digital Model Production Must Stay Connected—but Distinct

The model can support analysis, review and coordination, but engineering authority must remain explicit.

ENGINEERING

Structural Engineering Responsibility

Establishes the structural design basis and provides the approved information that controls the model.

  • Loading, load combinations and design criteria
  • Structural system and load-path decisions
  • Member, foundation and reinforcement design
  • Connection forces and design requirements
  • Structural analysis and calculations
  • Code interpretation and technical approval
  • Professional certification where required
Authority: Must remain with qualified and authorised professionals assigned by the contract and jurisdiction.
BIM MODEL

Structural BIM Modeling Responsibility

Develops and coordinates the approved structural information in the project’s digital model and documentation environment.

  • Model structural geometry and approved components
  • Apply agreed parameters, classifications and status
  • Coordinate architecture, structure and MEP interfaces
  • Prepare plans, sections, details and schedules
  • Maintain model links, coordinates and revisions
  • Identify missing or conflicting information
  • Issue model and documentation packages for review
Authority: Modelers represent approved information and raise RFIs instead of independently changing structural design intent.

REFERENCES
Linked Discipline Information

Architecture, civil, MEP, facade, equipment, point cloud and survey information referenced for coordination.

Model Purpose and Information Need

Specify What the Model Must Support—not Only a Generic LOD Number

Geometry, information, coordination and documentation requirements should be stated independently for each milestone.

01

Geometry Requirement

Define included elements, shapes, sizes, locations, openings, offsets, slopes, connection representation, tolerances and existing-condition limitations.

02

Information Requirement

Define parameters, classifications, material data, type information, model status, phase, zones, marks and required property values.

03

Model Use

Identify whether the model supports visualization, design coordination, drawing production, clash review, quantities, fabrication links or asset records.

04

Approval and Reliance

State the model author, reviewer, approval status, permitted use, exclusions, reliance limitations and relationship to signed engineering documents.

Structural BIM Coordination

Review Structural Interfaces before Drawings and Construction Packages Are Released

BIM coordination helps identify spatial and information conflicts, but the responsible disciplines must decide and approve the technical resolution.

Architecture and structural grids Walls, cores and framing Openings and penetrations MEP services and clearances Equipment and support zones Facade and edge conditions Embeds, anchors and sleeves Access and maintenance spaces

Frequently Asked Questions

Structural BIM Services FAQs

Common questions about model content, engineering responsibility, coordination, drawings, quantities, software and required project inputs.

What is included in Structural BIM Services?
The scope may include Revit structural modeling, structural steel and concrete systems, reinforcement representation, structural families, multidisciplinary coordination, clash review, model-driven drawings, schedules, quantities, exchange files and revision support.
Does Structural BIM include structural analysis and engineering design?
Only when expressly contracted and performed or verified by appropriately qualified and authorised engineers. BIM production itself represents and coordinates approved engineering information; it does not replace analysis, calculations or professional certification.
Which structural elements can be modeled?
Typical elements include foundations, pile caps, grade beams, columns, beams, slabs, walls, cores, structural steel, trusses, braces, openings, embeds, base plates, anchors, reinforcement and approved project-specific components.
Can the model be coordinated with architectural and MEP models?
Yes. Structural models can be federated with architectural, MEP, facade, equipment, civil and existing-condition references to identify clashes, clearance issues and unresolved interfaces.
Can structural drawings and schedules be produced from the model?
Yes. Plans, elevations, sections, details, schedules and quantity outputs can be produced from controlled model information. Each output should be checked for its intended use and current approval status.
Can quantity take-offs be extracted?
Yes, when the required elements, parameters, classification rules, measurement method and model status are defined. Quantity outputs should be reviewed against the project’s commercial and procurement requirements before reliance.
Which software platforms are supported?
Typical workflows may use Revit, Navisworks, AutoCAD, Tekla Structures, SDS2, Advance Steel and IFC-based exchange. The exact software version, templates, coordinates and output formats should be confirmed before production.
What information is needed for a Structural BIM quotation?
Share structural drawings, specifications, available architectural and MEP models, structural systems, project stage, required model uses, geometry and information requirements, software, coordinates, drawings, schedules, quantity needs, clash scope and delivery programme.
