BIM in 2007 – are we there yet?

Abstract: As the prevalence of BIM increases in A/E/C-FM disciplines it is timely to review the standards that are being utilised and how well they are serving the discipline. The analysis presented analyses the most common standard, the IAI’s IFC, from a meta-level and asks questions about the evolving model from the viewpoint of metrics for data models as well as a low level analysis of the accuracy and correctness of implementations of the data model interpret-ers. Metrics applied to the evolving versions of the IFC schema can indicate the trajectory of the schema and profile areas which may be of concern in the maintenance of the schema and applications that have to utilise the schema. Analysis of the approaches to importing and exporting data for design tools, based on the schema, help indicate how market ready the technology really is. Where commercial projects are starting to rely on the standards as a mechanism to reliably transfer semantically correct information there must be guarantees of the accuracy of the data as it is ma-nipulated by these design tools.
