Summary: TESTING SEMANTIC INTEROPERABILITY

With standardised semantic representations of construction objects able to be transferred
between major CAD systems, and other design tools, there is an expectation, supported by
compliance testing, that semantically consistent data will flow across the project team. This
assumption is questioned due to the known difficulties in mapping consistently and
completely between two distinct representations of an artifact. To test the ability of CAD,
and design tools, a number of buildings, described in a standard format, are loaded and then
saved directly back out of these tools and then checked for differences. A range of potential
differences has been postulated, and experiments show the existence of most categories of
differences when data files are examined.

The evolving IFC standard, published by the International Alliance for Interoperability (IAI
2005), allows for the transfer of semantically rich information between applications in the
