CAD to BIM Conversion

CAD to BIM Conversion & Design Development Modeling

If your project is starting from 2D CAD files, legacy drawings, or incomplete design sets, you need more than visuals—you need a clean, coordinated Revit model that teams can use for design development, coordination, and construction planning.

At HSE Contractors, we convert 2D drawings and existing documentation into accurate BIM models (Revit) built to your standards, LOD target, and real project workflows—so you can reduce errors early and move faster from design to execution.

What This Service Covers

• CAD-to-BIM conversion (2D drawings → 3D Revit model)
• Design Development (DD) modeling to support coordination and constructability
• Model cleanup + standardization (levels/grids, naming, shared parameters)
• Discipline modeling support (Architectural / Structural / MEP as scope requires)

Typical Deliverables

• Revit model(s) aligned to agreed LOD (commonly LOD 200–400)
• Sheets / views as required (plans, sections, details, coordination views)
• Model exports (RVT / IFC / DWG / PDF as requested)
• Basic QA/QC checks (model integrity, consistency, key dimensions)

Our Process (Simple and Predictable)

1. Intake: drawings/CAD files, scope, LOD target, standards, timeline
2. Setup: coordinates, levels/grids, naming conventions, parameters
3. Model build: convert CAD/drawings into structured Revit geometry + data
4. Review + refinements: incorporate markups and coordination feedback
5. Handoff: deliver final model + required exports

When CAD-to-BIM Is a Perfect Fit

• Renovations and existing conditions (where clean documentation is limited)
• Fast-track projects that need a model quickly for coordination
• Owner/GC teams needing a single source of truth to reduce RFIs
• Projects preparing for coordination before clash detection begins
