CAD to BIM Conversion Services

Traditional CAD drawings contain important design information, but they are often difficult to coordinate, analyse, update, and use across the complete project lifecycle. Vertus Engineering converts 2D CAD drawings and legacy documentation into structured, intelligent, and data-rich BIM models.

Our CAD to BIM conversion service is suitable for new construction, renovation, refurbishment, facility management, as-built documentation, and design coordination projects. Whether you need to convert a single drawing or a large drawing archive, our team can develop BIM models according to your project requirements, modelling standards, and required Level of Development.

Scope of CAD to BIM Conversion Services

Our scope is tailored to the specific requirements of each project, discipline, and delivery stage. From reviewing inputs and understanding technical requirements to preparing coordinated deliverables and incorporating client feedback, we provide structured support aligned with your drawings, specifications, standards, and commercial objectives. Each service scope is clearly defined to ensure accuracy, transparency, and seamless integration with your project team.

Typical Deliverables

  • Native BIM model
  • Architectural, structural, or MEP model
  • Federated model, where required
  • BIM model based on agreed LOD
  • Model views, plans, sections, and elevations
  • Schedules and quantity outputs
  • Model audit and quality report
  • IFC or agreed exchange format
  • As-built BIM model, where required

Our Conversion Process

We begin by reviewing the available CAD files, PDFs, scans, specifications, survey information, and modelling requirements. We then establish the modelling scope, project units, naming conventions, levels, families, LOD, and deliverable format before developing, checking, and submitting the BIM model.

Frequently Asked Questions

Yes. We can assess legacy and incomplete drawings and identify assumptions, missing information, and areas requiring clarification before modelling.

Yes. The conversion can cover one discipline or multiple disciplines, depending on the available information and project requirements.

The required LOD is agreed according to the project phase, intended use, design information, coordination requirements, and client BIM standards.

Yes. A suitably structured model can support quantity extraction, subject to model completeness and the agreed modelling scope.

Modernise your legacy drawings and create a coordinated digital project model with Vertus.
