Definition
HBIM, or Heritage BIM, is the use of building information modelling for historic and heritage structures. It creates detailed, information-rich digital models of old buildings, capturing not just their geometry but also their materials, condition, and historical significance.
Heritage buildings are often complex and irregular, so HBIM relies heavily on reality capture to record them accurately. The result is a valuable digital resource for understanding, conserving, and maintaining historic architecture.
In simple terms, HBIM applies BIM to historic buildings, turning them into rich, accurate digital models.
How It Works
HBIM typically begins with laser scanning or photogrammetry to capture a heritage building precisely as a point cloud. Because historic structures rarely follow standard shapes, modellers carefully build BIM elements that reflect their true, often irregular geometry.
The model is enriched with information about materials, construction, condition, and history. This creates a comprehensive record that supports conservation planning, restoration, and ongoing management of the heritage asset.
Applications
HBIM is used in conservation, restoration, research, and heritage management. It documents historic buildings accurately, supports planning of repairs and restoration, aids research and education, and provides a lasting digital record of culturally important structures.
Benefits
- Accurate models of complex historic buildings.

Frequently Asked Questions
What is HBIM used for?
It is used to document, conserve, restore, and manage historic buildings using detailed, information-rich digital models.
How is HBIM created?
It usually starts with laser scanning or photogrammetry, then careful modelling of the building’s true, often irregular geometry.
How is HBIM different from standard BIM?
HBIM focuses on existing historic structures with complex shapes and heritage information, rather than new, standardised construction.
Why is reality capture important for HBIM?
Historic buildings are irregular, so accurate scans are needed to model them faithfully.
