Abstract

The Industry Foundation Classes, IFC, are schemes created in EXPRESS for describing and transmitting unambiguous information on the construction industry. Currently, they are considered one of the most important agents in the quest for system interoperability in construction industry. More than ten years after its first version, however, the IFC's continued being used primarily on projects and test separated experiments. Among the various explanations for the low level of implementation is the limited number of tools (API) for developing new IFC-enabled applications. The information contained in the building model in IFC format is widely individualized, with the entities that represent building blocks being reduced to simple data types and geometric primitives, spread around different portions of the file. This feature needs to be reversed during the application creation that access building models, which greatly increases programming task and difficult to maintain code. This paper shows the main approaches for application development of building model data access in IFC format. In addition, it presents suggestions for the creation of an API that could allow semiautomatic metacompilation of Java Library classes corresponding to IFC entities. Such tool provides developers with more direct access methods. Thus, applications could be created easily and faster, helping to disseminate the IFC schema in the building industry. Keywords: BIM, IFC, ifcXML, metacompilation, binding.
