Renovation projects often begin with uncertainty about what is actually built. Scan-to-BIM reduces that uncertainty by converting captured site data into a Revit model and drawings that designers and contractors can rely on.
Step 1 — Capture and collect
Inputs can include laser-scan point clouds, Matterport captures, existing CAD or PDF drawings, photos and field measurements. The more complete the data, the fewer assumptions are needed later.
Step 2 — Agree on the level of development
Before modeling starts, the team should agree on what will be modeled and to what level of detail. Modeling every bolt is rarely necessary; modeling walls, openings, structure and major MEP elements accurately usually is.
Step 3 — Model in Revit
- Walls, floors, roofs, openings and structure are modeled against the point cloud.
- Visible MEP elements are modeled where the scope includes them.
- Existing phases are set up so new work can be designed directly in the model.
Step 4 — Document
Plans, sections and elevations are produced from the model. Areas that could not be captured are clearly noted for field verification.
The goal is not a perfect digital twin — it is a model accurate enough for the decisions the project needs to make.
A reliable existing-conditions model shortens design, improves coordination and reduces surprises during construction.
