What is HBIM? The Digital Guardian of Cultural Heritage

Historical Building Information Modeling (H-BIM) is a specialized application of BIM technology used for the preservation, documentation, and management of historic structures. Traditional methods are often inadequate (wall curvatures, cracks, ornaments, etc.). Laser scanning and photogrammetry overcome these challenges by providing millimetric precision data.

Traditional vs. HBIM

Traditional: Manual measurements are taken, error margins are high, inaccessible details like ceiling ornaments may be missing.

HBIM: With non-contact laser scanning, every stone and every crack is digitally copied.

Applications

**Deformation Analysis

** How much the walls deviate from plumb and the condition of arches are analyzed with color maps (Heatmaps).

**Survey Drawing

** The most accurate survey drawings required for Heritage Council approval processes are produced.

**Virtualization (VR/AR)

** Museums and historic sites can be opened to visitors through virtual tours.

How Is It Done?

Data Collection: Laser Scanners (Terrestrial) + Drone (Photogrammetry).

Processing: Data is merged and placed in a registered coordinate system (ITRF).

Modeling: Irregular forms are modeled in Revit using "in-place family" methods.

Conclusion

Digital documentation is now a necessity to pass on our cultural heritage to future generations. At EosProje, we are here for you with our expert team in HBIM processes.
