Short answer: We laser scan your building, register the scans into an accurate point cloud, and model it in Revit to your required Level of Development — architectural, structural, and MEP elements coordinated into one BIM you can build from.
Scan-to-BIM converts a real, existing building into an accurate Revit model. We capture the space with laser scanning, then model directly from the point cloud to the Level of Development (LOD) your project needs. Here is how the workflow runs from field to model.
The scan-to-bim process, step by step
- Scope & LOD agreement. We confirm which disciplines (architectural, structural, MEP) and what Level of Development (LOD 200–350) your model needs, and how it will be used downstream.
- On-site laser scanning. Survey-grade scanners capture the building as a millimeter-accurate point cloud, including structure and mechanical systems above ceilings.
- Registration. Scans are aligned into one coordinated point cloud with a documented accuracy check, then imported into Revit.
- Revit modeling. Our modelers build native Revit elements directly from the point cloud to the agreed LOD and discipline scope.
- QA & clash review. The model is checked against the point cloud for accuracy and reviewed for coordination before delivery.
- Delivery. You receive the native Revit (.rvt) model, plus IFC / Navisworks exports and the point cloud if needed.
What you receive
- Native Revit (.rvt) model at your LOD
- Architectural, structural &/or MEP elements as scoped
- Coordinated, clash-checked geometry
- IFC and Navisworks exports
- Registered point cloud archive (optional)
Typical timeline
Field capture is typically one to two days; modeling turnaround depends on size, LOD, and disciplines — usually two to six weeks. We can phase deliveries by floor or discipline.

Why CAD Construct LLC
We bridge field and model in-house — the same team that scans your building builds the BIM — so nothing is lost in translation, and every element traces back to survey-grade data.
Frequently asked questions
What is Scan-to-BIM?
\nScan-to-BIM is the process of laser scanning an existing building and using that point cloud to build an accurate 3D BIM (usually a Revit model) of what is really there.
\n
What is LOD and which do I need?
\n
Level of Development describes how detailed and reliable the model elements are. LOD 200 is generic, LOD 300 is accurate geometry, LOD 350 adds connections and clearances. We help you pick the right level for your use.
\n
Which disciplines can you model?
\n
Architectural, structural, and MEP — individually or coordinated together, depending on your scope.
\n
How accurate is the model?
\n
Because it is built from a registered, survey-grade point cloud, geometry is typically accurate to a few millimeters.
\n
Do you deliver the point cloud too?
\n
Yes. You can keep the registered point cloud alongside the Revit model for verification and future work.
\n
How much does Scan-to-BIM cost?
\n
Pricing depends on area, LOD, and disciplines. Use our Scan-to-BIM cost calculator for a ballpark, or send a floor plan for a fixed quote.
\n
Can you match our Revit standards?
\n
Yes — we can work to your template, naming, and family standards.
