“…For this, GUIDs are typically used in a shallow or deep tree comparison of IFC models (Nour, 2007). Yet, this approach has been widely criticized due to the inconsistent persistence of GUIDS (Weise and Katranuschkov, 2004;Kiviniemi et al, 2005;Nour and Beucke, 2008;Hjelseth and Nisbet, 2010). These resulting inconsistent, missing, or replaced GUIDs can potentially lead to costly calculations, and quality compromises in a round trip data exchange.…”

“…Thus, there is an abstraction gap between current BIM tools and the structural nature of IFC models. As an alternative, object versioning is a developing approach that applies a control mechanism to an object in a BIM, at an attribute level, enabling conflict detection and change management on objects rather than on files or models (Nour and Beucke, 2008;.…”

Model server enabled management of collaborative changes in building information models

The issues and challenges involved in controlling the collaborative changes in a Building Information Modeling (BIM) data repository, in a multi-model collaboration environment, are discussed. It is suggested that managing iterative changes in BIMs is a database problem, exacerbated by the long transaction times needed to support collaborative design progression. This is yet to be resolved in the construction industry and better solutions are needed to support the underlying workflows and computing operations for seamless collaboration on BIMs. With this in mind, this paper proposes the use of the structural and semantic characteristics of BIM objects as a mechanism for tracking changes across co-developed solutions. The creation of object signatures, using hash codes derived from their characteristics, provides a potential mechanism for object comparison and effective change recognition and management.

“…This has been largely achieved through the reliance on data exchange standards or API level customisation for interoperability [16]. The import and export functionality of CAD and BIM tools dealing with Industry Foundation Classes (IFC) models utilize the STEP API for EXPRESS defined data to access attributes of objects created at run time [17]. Also, the implementation parts of many contemporary research efforts on BIM extension have relied on API programming technology to establish communication with models in existing BIM-enabled platforms.…”

The provision of Application Programming Interface (API) in BIM-enable tools can contribute to facilitating BIM-related research. APIs are useful links for running plug-ins and external programmes but they are yet to be fully exploited in expanding the BIM scope. The modelling of n-Dimensional (nD) building performance measures can potentially benefit from BIM extension through API implementations. Sustainability is one such measure associated with buildings. For the structural engineer, recent design criteria have put great emphasis on the sustainability credentials as part of the traditional criteria of structural integrity, constructability and cost. This paper examines the utilization of API in BIM extension and presents a demonstration of an API application to embed sustainability issues into the appraisal process of structural conceptual design options in BIM. It concludes that API implementations are useful in expanding the BIM scope. Also, the approach including process modelling, algorithms and object-based instantiations demonstrated in the API implementation can be applicable to other nD building performance measures as may be relevant to the various professional platforms in the construction domain.

“…File-based exchange in a fragmented environment also causes data duplicity and hence inconsistency. Therefore, researchers have developed IFC based BIM servers using web based object-relational databases that considers partial information exchange (Nour 2007;Kang and Lee 2009;Nour and Karl 2008). These frameworks however have limitations on the size of data that can be exchanged, as relational databases may not be able to store and exchange large amounts of data in a web based environment.…”
