Digital twins for the built environment

BuildingSmart International has also created a Digital Twin working group in 2020, set on deciding the way forward from BIM and help develop open standards focused around three main areas: data models, data management & integration, data security & privacy. Within their white paper [59], BuildingSmart mention possible links to the ISO 55000 (Asset management — Overview, principles and terminology). On the macro scale, the standards developed by the Sustainable cities and communities committee (ISO TC/268) around the subject of smart cities should also play an important role when adopting a DT strategy.
IFC development for BIM application to railway projects

It is common knowledge that the various stakeholders in the AECO sector, both at the project level and in the different phases of work and exploration, sometimes do not use compatible applications in carrying out their work, others often need inputs from different specialties, which are not always available with the necessary quality and brevity, or still have different levels of knowledge and mastery in relation to the BIM methodology. In this sense, the study of interoperability is a topic of the greatest relevance and timeliness, considering several types: i) interoperability between applications; ii) interoperability between different stakeholders and specialties; iii) interoperability between people with very different levels of education and/or knowledge in the area. The issue of interoperability is inseparable from buildingSMART, which has as main objective to contribute to the effective interconnection between the different stakeholders in the construction industry, throughout its life cycle, and contribute to the creation and dissemination of protocols for information exchange.
BIM-based model checking in a business process management environment

One of the main challenges has been the lack of standardization of rule and design representation. An ongoing effort is made by the organization buildingSMART to develop open-standards for representing BIM-models to increase interoperability, lessening the need for managing information (Golabchi & Kamat, 2013). Moreover, various open-standards for rule formulations are available, but need to be manually updated (Dimyadi & Amor, 2013).
A model-based approach to convert a building BIM-IFC data set model into CityGML
Published in Journal of Spatial Science, 2020

BIM model specifications are developed by buildingSMART, a worldwide recognised authority: international standards are defined according to a set of five technical categories. First of all, carrying digital data is eased by industry foundation classes (IFC), recorded under the ISO 16739. The IFC schema lays upon a series of fundamental concepts. A detailed representation of a process can be found in its process map, described through the information delivery manual (IDM). Translating descriptive processes into technical requirements is resolved by the use of model view definitions (MVD). A complete ontology description integrates into the logic of terms mapping covered within the international framework for dictionaries (IFD). A change coordination format is shown in the BIM collaboration format (BCF) to enhance communication and overall project quality.
Extending the current model view definition standards to support multi-storey modular building projects
Published in Architectural Engineering and Design Management, 2018
To facilitate digital IEs in the construction industry, the international alliance for interoperability (later named buildingSMART International) initiated standardisation of ontology-based semantic IEs in 1994 (Nawari & Sgambelluri, 2010). buildingSMART International is a non-profit international organisation that develops standards for implementation of BIM in the AEC industry (buildingSMART International, 2016b). As depicted in Figure 2, efforts related to IE in buildingSMART International are focused on three major areas: (1) Information Delivery Manual (IDM), (2) International Framework for Dictionary (IFD), and (3) Industry Foundation Classes (IFC) data schema. IDM is a standard for the processes and information requirements in construction projects, IFD is a data dictionary and a standard for the terminology and data model for the information related to construction projects, and IFC is an open standard data schema for data management and IE in the construction industry. At the conjunction of IDM and IFC, relevant MVDs are defined as translation of IDM Exchange Requirements (ERs) in the IFC language.
An open world adventure: The quest for a global BIM ecosystem
Published in Construction Research and Innovation, 2019
There is, however, a need to make use of the biggest advantage of open-source software creation by making the development of standards more transparent and accessible for those who are not members of its chapters. To this end, BuildingSMART is developing its site on GitHub – Microsoft’s software development platform – and will upload its standards to it using UML (unified modelling language), which is a general purpose code.
