Definition
Scan-to-BIM is the process of turning a laser scan of an existing building into an accurate BIM model. It starts with capturing reality as a point cloud, then uses that data to create an intelligent, information-rich digital model of the structure as it truly exists.
This bridges the gap between real, existing buildings and the digital BIM workflows used for design and construction. It is especially valuable for renovation, refurbishment, and documentation, where reliable existing-condition data is essential.
In simple terms, scan-to-BIM converts a 3D scan of a real building into a usable, detailed BIM model.
How It Works
The process begins with laser scanning the building to produce a detailed point cloud of its actual dimensions and features. This point cloud is cleaned and registered into a single accurate dataset representing the structure.
Modellers then use the point cloud as a reference to build BIM elements, such as walls, floors, and columns, that match the real geometry. The finished BIM model reflects the building as-built and carries the data needed for design, coordination, and management.
Applications
Scan-to-BIM is used in renovation, refurbishment, heritage, and facility management. It provides accurate models of existing buildings for design and coordination, supports clash-free planning of alterations, and creates reliable digital records where original drawings are missing or outdated.
Benefits
- Accurate BIM models of existing buildings.
- Reliable existing-condition data for design.
- Fewer errors and surprises during renovation.
- A digital record where drawings are missing.
- A bridge from reality capture to BIM workflows.

Frequently Asked Questions
What is scan-to-BIM used for?
It is used to create accurate BIM models of existing buildings for renovation, refurbishment, heritage, and facility management.
How does scan-to-BIM work?
A building is laser scanned into a point cloud, which is then used as a reference to build an accurate BIM model.
Why is scan-to-BIM useful for renovations?
It captures the true as-built condition of a building, reducing errors and surprises when planning alterations.
What is the output of scan-to-BIM?
The output is an information-rich BIM model that reflects the existing building as it truly is.
