What Are Scan-to-BIM Services?
Scan-to-BIM is a process where an existing building is digitally captured using 3D scanning technology and then converted into a structured Building Information Model (BIM).
This allows architects, engineers, and design teams to work from an accurate digital representation of the building when planning renovations, refurbishments, or extensions.
The process is commonly used for existing buildings where accurate drawings are not available or may be outdated.
How Scan-to-BIM Works
Scan-to-BIM typically involves three main stages.
1. Digital Building Capture
A LiDAR scanning system such as the Matterport Pro3 is used to capture the building.
This creates a detailed digital record of the building geometry and spatial layout.
For smaller buildings such as houses or offices, the capture process typically takes around 1–2 hours onsite.
2. Point Cloud Creation
The captured data is exported as a point cloud file, typically in E57 format.
This file contains millions of measured points representing the geometry of the building.
Architects and engineers can import this point cloud into software such as:
Revit
AutoCAD
Navisworks
The point cloud can then be used as a reference when modelling the building.
3. BIM Model Creation
Alternatively, the point cloud can be converted into a fully structured BIM model.
These models are typically delivered in Revit format and can be created at different levels of detail depending on project requirements.
Typical modelling levels include:
LOD 200 – general building form and major elements
LOD 300 – more detailed architectural elements suitable for design development
For many projects, BIM models can be delivered within around one week after capture.
Accuracy of Scan-to-BIM Using Matterport
Matterport Pro3 uses LiDAR technology capable of capturing buildings with accuracy of approximately ±20mm over 10 metres under typical conditions.
This level of accuracy is suitable for many applications including:
Existing conditions documentation
Renovation planning
Architectural design reference
Asset documentation
Why Architects Use Scan-to-BIM
Scan-to-BIM services help architects and design teams work more efficiently when documenting existing buildings.
Benefits include:
Accurate digital record of existing conditions
Reduced time spent on manual measurement
Fewer site visits required during design
Easier coordination with consultants
Faster preparation of design models
Trial Scan-to-BIM Before Purchasing Equipment
Many architecture firms are interested in scanning technology but prefer to trial the workflow before investing in hardware.
Using a professional capture service allows firms to test the process and evaluate how the data integrates into their design workflow before purchasing their own equipment.
Typical Pricing
As a general guide:
Site capture: starting from around $300 for houses and small offices
BIM model creation: typically from around $1,500, depending on building size and modelling level
Larger buildings or higher levels of detail may require project-specific pricing.
Common Questions About Scan-to-BIM
Can Architects work directly from the point cloud?
Yes. Many design teams import the E57 point cloud into Revit or AutoCAD and build their own model using the scan data as a reference.
Do I need to Buy a Matterport camera to use Scan-to-BIM?
No. Many architecture firms use capture services to scan projects rather than owning their own equipment.
How long does Scan-to-BIM take?
For smaller buildings, capture usually takes 1–2 hours onsite, with BIM models typically delivered within around one week.
