Can you do Scan to BIM with an iPhone?

Short answer

Yes, for the right job. Phone LiDAR typically reaches centimetre-level accuracy for building elements, which suits LOD 200 to LOD 300 models of small, uncluttered spaces: offices, apartments, small shops, single rooms. It is not suitable where tight tolerances, long ranges, tall spaces or legal survey records are needed.

What the studies found

• A 2024 study of iPhone 13 Pro LiDAR for BIM compared it with a FARO terrestrial scanner and a distometer, then modeled in Revit. Most measured elements (windows, doors, columns, walls) fell in the centimetre range, with some in the millimetre range, and the authors noted point-cloud drift but judged the data usable for BIM.
• A 2023 iPad Pro study found very low noise for static scanning, with average deviation rising to about 1 cm when the device moved, and better results in smaller areas.
• App makers give their own figures; Polycam, for example, states about ±½ inch on standard interiors and lower accuracy in very large, cluttered or reflective spaces. Treat vendor figures as indicative.

Where phone scans work

• Small renovation and fit-out projects at LOD 200 to 300.
• Quick existing-conditions checks before a full survey.
• Furniture, fixtures and equipment inventories for facilities teams.
• Digital twins and simulation of rooms, where completeness matters more than millimetres.

Two of our public LiDAR samples, a workshop and a medical warehouse, were rebuilt from phone captures from Niantic Spatial into hundreds of individually editable objects, with Revit downloads.

Where they do not

• Spaces larger than a few hundred square meters, where drift accumulates.
• High ceilings, plant rooms and anything beyond a few meters' range.
• Specifications at LOA30 or tighter (see how to write a Scan to BIM specification).
• Reflective, dark or glass-heavy spaces.

How to capture a usable phone scan

1. Clear the room of people and move slowly, overlapping your path.
2. Capture closed loops: return to where you started so the app can correct drift.
3. Scan in sections for larger areas and keep each section small.
4. Measure one or two reference distances with a laser measure to check scale.
5. Export the point cloud (for example PLY or E57) rather than only a mesh, if the app allows. See point cloud file formats.

When to step up

If the phone scan shows the job is bigger than expected, move to mobile SLAM or a terrestrial scanner (see choosing a scanner). Either way, you can upload a scan and get a separated Revit and IFC model back within 48 hours.
