“…As a technique for realising a cyber–physical system [ 38 , 39 ], the DT method integrates multiple new information technologies such as the Internet, the IoT, artificial intelligence, and digital modelling to achieve interaction between the real physical world and the virtual digital world, which helps systems in various industries to achieve high-level intelligence and automation [ 40 ]. In [ 41 ], the applications of BIM were reviewed to pave the way for construction DT, and the areas for future research in the AEC industry were elaborated. At present, digital twins have been applied in the field of smart cities [ 42 ], building construction, maintenance, and strengthening operations [ 43 , 44 ].…”

With the development of the next generation of information technology, an increasing amount of attention is being paid to smart residential spaces, including smart cities, smart buildings, and smart homes. Building indoor safety intelligence is an important research topic. However, current indoor safety management methods cannot comprehensively analyse safety data, owing to a poor combination of safety management and building information. Additionally, the judgement of danger depends significantly on the experience of the safety management staff. In this study, digital twins (DTs) are introduced to building indoor safety management. A framework for an indoor safety management system based on DT is proposed which exploits the Internet of Things (IoT), building information modelling (BIM), the Internet, and support vector machines (SVMs) to improve the level of intelligence for building indoor safety management. A DT model (DTM) is developed using BIM integrated with operation information collected by IoT sensors. The trained SVM model is used to automatically obtain the types and levels of danger by processing the data in the DTM. The Internet is a medium for interactions between people and systems. A building in the bobsleigh and sled stadium for the Beijing Winter Olympics is considered as an example; the proposed system realises the functions of the scene display of the operation status, danger warning and positioning, danger classification and level assessment, and danger handling suggestions.

“…The AEC industry is facing similar challenges while still operating in a document-centric manner. Even the great effort in researching multidimensional BIM in the last decades didn´t lead to a sufficient improvement in information flow [15]. The chance towards a model-centric approach becomes a necessity for the AEC industry to solve the long existing problems.…”

“…Research efforts conducted during the past decades show that while modeling has already moved beyond the n-dimensional development of BIM, the degree of integration between different systems and stakeholders can still be greatly improved [15]. Given the various use-cases applied throughout the construction project lifecycle and their diverse requirements, there is currently little interoperability and automation potential to leverage the use of BIM [15]. Although the advances in vendor-independent formats such as Industry Foundation Classes (IFC) have a significant impact on the development of integrated methods for the exchange of construction data [15].…”

The increased complexity of construction projects requires the involvement of a wide range of organizations throughout the project lifecycle-from conceptual planning to decommissioning. Construction project teams, therefore, differ from teams in other industries as they comprise individuals who are employed by organizations that conduct different businesses. These many separate organizations working together in a close harmony over the duration of the project is fundamental to the overall business of construction. Project success relies heavily on the management of the flow of information among players and access to the right information is vital to efficiently perform the work. Therefore, an efficient information access and effective information exchange methods internally and externally with other organizations needs to be achieved. The model-centric approach introduces a unique solution to solve the problems with the information jungle, inconsistency, and disintegration associated with the traditional document-centric approach. As such, a coherent use of information management is required to merge, comanage, and semantically connect the information and artifacts generated throughout the project phases. Adopting a model-centric approach creates a single point of truth that centralizes information and facilitates access to it. A transformation plan is needed to outline the shift of the construction from document-centric to model-centric. This paper proposes a strategy to support the model-centric transformation of the Architecture, Engineering, and Construction (AEC) industry. Five strategic objectives are outlined and discussed in this paper highlighting considerations that need to be made to enable this transformation. This study describes the "what" necessary to enable and support a model-centric AEC industry.

“…In the manufacturing sector, the digital twin can be regarded as a source of useful information across the entire product lifecycle, for instance, it applies to the building and infrastructure lifecycles. Therefore, the construction digital twin will be conducive to shifting from a smart and lean construction process towards smart lifecycle management [11]. By applying digital twins in their work, engineers can foresee and avoid possible problems as well as take cradle-to-grave responsibility for the constructions they design, taking into account both external and internal factors.…”

The article considers industrial applications of digital twins and their contribution to decision-making and prevention of failures in manufacturing. Virtual laboratories are described as an example of using digital twins not only in industry but also for educational purposes. The article is also focused on the value of physical and virtual investigations through the prism of content and language integrated learning approach (CLIL) and it offers recommendations for combining the two to strengthen science inquiry learning and job-relevant learning. Students conduct online investigations resulting in interdisciplinary team interaction and knowledge integration. Adopting the CLIL approach changes engineering students’ attitudes to learning a foreign language, drums up their academic interest, and strengthens their motivation. In addition, the article describes how neural networks are applied for the simulation of physical processes in a virtual laboratory. The advantages of using virtual laboratories for professional-oriented training include linking observable and unobservable phenomena, pointing out essential information, and providing online, adaptive guidance. To evaluate the efficiency of the virtual laboratory environment, we conducted an experiment to assess the effectiveness of an integrated learning course with the elements of a virtual laboratory. The sample was 48 students (23 of them were enrolled on the course based on integrated learning with elements of virtual environment; 25 students studied professional discipline and professional English separately). To collect the data two online testing on English were conducted. The professional discipline was evaluated once at the end of the semester. In addition, we conducted an online survey on motivation for students of both groups to reveal the influence of educational process organization on this indicator. The results of the experiment allowed us to ascertain that the CLIL approach in the virtual laboratory environment resulted in better outcomes and helped the students adopt a more positive attitude to learning English.
