Coordinate systems have different origins, scales, and orientations. When they don't match across disciplines, models that look correct in isolation end up misregistered — and the problem often doesn't surface until it's expensive to fix. This tutorial, taught by Štefan Jaud of Jaud IT GmbH through buildingSMART Deutschland (bSD), covers IFC 4.3 georeferencing at the schema level, with the CRS theory and transformation math that make it work in practice.
Aimed at BIM engineers and infrastructure specialists who already deal with georeferenced models and want to know what's actually going on at the schema level.

What the tutorial covers
- Coordinate reference systems: projected, topocentric, and geocentric
- Transformations between reference systems and the distortions they introduce
- IFC 4.3 georeferencing: IfcProjectedCRS, IfcMapConversion, and how to apply them
- Aligning georeferenced models across disciplines without coordinate drift
- Common failure modes in multidisciplinary projects and how to catch them early
Instructor
Štefan is our founder and managing director. His doctorate at TU Munich is on georeferencing in BIM. That research is what this course is built on. He also runs a two-day georeferencing course at VDI Wissensforum.
Format and recognition
Three hours, online via GoToWebinar. The October 2024 edition was accredited as continuing education by six German engineering and architecture chambers, for 4 credit hours.
