3D Modeling

Architectural, structural, and MEP modeling in Revit, Tekla, AutoCAD, Civil 3D, and Blender. We produce construction documents, shop drawings, bid-set packages, and coordination models at the LOD your project requires.

Service Overview

3D BIM modeling is the foundation of every downstream VDC workflow. High-quality, information-rich models make coordination faster, documentation more accurate, and facility management more effective. At EZ-VDC, we build Revit models for all building systems (structural, architectural, MEP, and civil) to project-specific LOD requirements, using a model-first approach where the 3D geometry and its embedded data are the single source of truth for all construction documentation.

How We Work
1

Document Review & LOD Planning

We review all available drawings, specifications, and reference models to establish modeling scope, LOD requirements per system, and a project-specific modeling standards guide.

2

Model Development

Disciplined modeling in Revit following established standards: correct family types, parameter mapping, and system connectivity from the start, not as a later cleanup task.

3

Internal QA/QC

Every model goes through our checklist-based QA process: geometry accuracy, naming compliance, parameter completeness, and basic self-clash review before client delivery.

4

Client Review & Revision Cycles

Models are shared via ACC or Revizto for client review, with a structured comment response process ensuring all markups are tracked and addressed in subsequent releases.

5

Final Handoff

Deliverables include the discipline Revit model, linked file structure, model transmittal, and parameter legend: everything needed to hand off to coordination or construction teams.

Why It Matters
A correct LOD 350 model eliminates the need for separate shop drawing coordination
Parametric families carry specification data, enabling automated scheduling and quantity take-offs
Model-generated documents always reflect the latest geometry: no more out-of-sync drawings
High-quality input models reduce downstream coordination time by 30–50%
Revit models become the FM asset register when handed over to operations teams
Frequently Asked Questions

What LOD levels do you model to, and what does each include?

We model from LOD 100 (massing/concept) through LOD 400 (fabrication-ready). For design documentation, LOD 300 is standard: accurate geometry, correct family types, and manufacturer-agnostic specifications. LOD 350 adds connection details and supports. LOD 400 adds fabrication dimensions and is required for shop drawing production. We define LOD per discipline at project kickoff.

Can you convert existing 2D CAD drawings or PDFs into a BIM model?

Yes. PDF-to-BIM and CAD-to-BIM conversions are a common engagement type. We work from architectural and structural PDFs, contractor as-builts, and legacy CAD files. The accuracy of the resulting model is tied to the quality of source information — we document any areas where source data was insufficient and flag assumptions for client review before finalizing.

What software do you use for 3D modeling?

Revit is our primary platform for architectural, structural, and MEP models. For structural steel we also work in Tekla Structures. For site and infrastructure, Civil 3D and InfraWorks. Concept visualization uses Blender and Enscape. All models are delivered in native format plus IFC for interoperability with other platforms.

How do you handle model quality control before delivery?

Every model passes a three-stage QA process: internal checklist review covering geometry accuracy, family compliance, and naming conventions; basic self-clash review catching conflicts within the same discipline before sharing; and client review via ACC or Revizto with tracked markup response. We maintain a revision log and address all markups before each delivery milestone.

How is 3D BIM modeling priced?

3D modeling is typically priced per square foot or per discipline-hour depending on project type. Commercial Revit models run approximately $0.10–$0.30/SF for architecture. MEP modeling is scoped per system. Complex structures such as hospitals and data centers are quoted higher due to system density. We provide detailed fixed-fee proposals broken down by discipline and LOD.
