Kurzfassung englisch:
Several data exchange standards support the open exchange of building data. Industry Foundation Classes (IFC) standard is the most widely implemented within software solutions and the most used in practice. This standard is developed by buildingSMART International and describes a schema defined with EXPRESS data modelling language also including the data validation rules.
Because of its richness and redundancy, inadequate support of specific disciplines, but also its variable application within software solutions, open data exchange has not achieved a satisfying level of reliability. To transfer building data, actors that exchange information turn to various alternative data exchange possibilities like other open exchange formats, software specific data exchange software solutions, and workarounds.
This paper aims at analysing the problem of data exchange among disciplines with varying exchange requirements. Depending on the discipline and its specific requirements, data exchange potentials with IFC differ largely. Overcoming the interoperability problems are often discipline-specific: providing new schemas, incorporating strict workflows (for native and receiving application), or using 2D drawing -based exchange, physically or digitally.
In this paper, two workflows that follow BIM modelling process are examined. The first step in both workflows is the creation of architectural BIM model. Consequently, two data transfers are considered: to structural analysis and to life cycle analysis (LCA) software tools. The actors´ exchange requirements are identified, as well as their description through the data flow.
Thereby, the adequacy of a predefined set of exchange requirements in the construction industry is assessed. Results show that IFC schema, or any other schema defined in the same way, is not an optimal answer to the end user needs. An improved open exchange based framework is proposed with a data management concept that supports it. Finally, the implementation of the new concept aims to enhance the technological development of open standards and draw it towards the seamless exchange.
