How to Compare Point Clouds and 3D Models

Anticipate errors before they reach the site

AEC professionals are precision-driven. They need access to a truthful representation of the field throughout the project, not just at kick-off. Superposing the BIM model on the point cloud surfaces every gap: a wall that's 5 cm off, a slab level that shifted, a pipe that clashes with a beam. Catching these early turns expensive site fixes into simple model updates.

How ATIS.cloud automates the comparison

You upload your point cloud and your BIM model (IFC) to ATIS.cloud. The platform automatically detects deviations and renders a color-coded point cloud: areas where the scan matches the model stay neutral, areas that deviate shine in the color scale of the gap size. The team sees, in seconds, where reality and design drift apart.

When to run a scan-vs-BIM comparison

• At project kickoff: confirm the as-built state before design work starts
• Mid-project milestones: verify construction is following the plan
• Just before handover: generate the final as-built delivery
• On renovation and retrofit projects: spot undocumented changes vs. historical drawings
• For facility management: keep the digital twin aligned with the real building over time
