Digital Survey of Historic Fabric
How laser scanning and photogrammetry have changed the way we document and restore historic buildings.
Surveying a historic house by hand with tape and level takes weeks, and its errors become expensive later on.
Point clouds
With a terrestrial laser scanner we capture an entire house in two days. The resulting point cloud records every crack and wall deformation to within a few millimetres.
From point cloud to model
This data feeds directly into a BIM model that underpins the restoration design. Drone photogrammetry fills in roofs and domes that are hard to reach.
In Oudlajan, digital surveys of fourteen houses formed the basis of the restoration files and a permanent archive for the quarter.
