The BIG5 Challenges

Over the next five years, BIM will drive not just the transformation of the built environment, but also the geospatial industry itself. Its successful implementation is dependent on collaboration and Survey4BIM has identified the five technical geospatial challenges to geo-enable implementation of BIM level 2.

Survey4BIM has identified these challenges as:

  • Accuracy
  • Generalisation
  • Interoperability
  • Level of Detail
  • Meta-Data


Bernhard Becker is leading the charge on the discussion of Accuracy.  This is a fundamental element of Survey4BIM – because however well your project is managed in the Digital Domain – it matters little if it ends up getting built or recorded in the wrong geo-spatial location.

Bernhard has been doing some work with the RICS:
