A REVIEW OF IFC STANDARDIZATION – INTEROPERABILITY THROUGH COMPLEMENTARY DEVELOPMENT APPROACHES

The Industry Foundation Classes (IFC) data model has been in development by an industry consortium since 1994; during this time the industry context, standardization organization, resource availability, and technology development have exposed the standardization process to a dynamic environment. While the overarching mission of IFC standardization has always been to provide interoperability between AEC/FM software applications and actors, both the goals and the views on how to best achieve those goals have changed throghout the years. Despite the fact that IFC has enjoyed sustained professional and scholarly interest throughout its development, reflective socio-technical studies on the subject are largely non-existent. This study reviews the major shifts in the development process of the IFC standard from its origins in the early 1990s up to 2011, splitting the timeline into four distinct phases. A finding of the review is that the IFC standardization process has utilized complementary minimalist and structuralist approaches for different phases of the standardization process- balancing exhaustive structuralism and implementable minimalism.
