For the heritage-protected reconstruction of an ancient industrial building in Magdeburg (Germany), 3D laser scanning has been applied as method of measurement. In the scope of restoration works and renovations, 22 loft apartments shall be created in the complex.

For an authentic reconstruction of the facade as part of the renovations, detailed and accurate façade plans, which are true to scale, are necessary. As a result of the space restrictions, the 17 m high façade can only be imaged by a contact-free measuring technique. The smallest of the three facades, the east façade, is fitted with several jumps in the façade and inclined façade components by which the effort for the survey as well as for the analysis and interpretation is increased. A highly accurate dimensional as-built documentation is essential for getting precise plans as a basis for planning. By laser scanning, the façade details, such as window opening and breaks in the wall, could be captured in high accuracy.

Facts

  • survey of three facades accomplished via laser scanner
  • analysis and interpretation of data with the software PointCab and Geograf on a scale of 1:50
  • 25 laser scanner positions
  • a total of 1,720 m² facade has been measured (thereof 469 m² façade are on the yard side, 442 m² on the east side and 810 m² of the street view)
  • survey: 5 hours (just one assistant)

Why PointCab?

  • fast generation of orthophotos in 1 hour (3 GB)
  • scaled and detailed images
  • data could easily be read in the CAD system Geograf, further processing possible
  • generate views and sections

The fast generation of scaled orthophotos allows the fast analysis and interpretation in Geograf.
