What is Scan to BIM?

It is the process of converting an existing building, bridge, or facility into a 3D Building Information Model (BIM) using laser scanning (point cloud) data. This model is not just a visual representation; it is an intelligent database containing the geometric, technical, and quantity information of the structure.

The 5-Step Process

The Scan to BIM process begins with fieldwork and ends in the office environment.

**Field Planning (Survey Plan)

** Site reconnaissance and determination of scanner positions.

**Data Collection (Laser Scanning)

** Point cloud data collection with LiDAR devices like Leica RTC360.

**Registration

** Merging fragmented scans into a single coordinate system (Autodesk ReCap / Cyclone).

**Modeling (BIM Production)

** Modeling architectural, structural, and MEP elements in Revit by tracing over the point cloud.

**Quality Control (QA/QC)

** Analyzing deviations between the model and the point cloud (Navisworks / Verity).

Why Is It Necessary?

In renovation projects, drawings of the existing structure are often lost or outdated (walls demolished, installations changed). With Scan to BIM, the "as-built" condition is documented with 100% accuracy.

Risk Management: Clashes are detected at the design stage (Clash Detection).

Cost Control: The most accurate quantity lists are obtained for manufacturing.

Facility Management: An up-to-date digital twin is provided for maintenance and repair processes.
