The industry foundation classes (IFC) : ready for indoor cadastre?
Clemen, Christian and Lothar Grundig
The term indoor cadastree describes an information system that integrates the functional components of acquisition, management, analysis and presentation of building indoor information. In contrast to the term building information systemm (BIM) the focus is set on the data acquisition. From a surveyorrs point of view, the redundant geodetic measurements are the primary data. The measurement results establish the basis for planning and construction. This article figures out how engineering surveyors can use the Industry Foundation Classes (IFC) in order to document the survey result. The Industry Foundation Classes (IFC) provide a data model for 3D-Building-Information- Models (BIM) which enables all actors in a planning, construction and management process to exchange information in an integrated data pool. The model is not focused on drawing exchange, like DXF, but considers building components as what they are: objects! ifcXML-files can be used as a software independent model-based exchange format. The objective to use the IFC Model is to improve communication, productivity, delivery time, cost, and quality throughout the whole building life cycle. The IFC model is also interesting from the administrative point of view. For instance Singapore Building and Construction Authority uses the IFC for electronic regulation-checking.
