Actors in the Architecture, Engineering, Construction, Owner and Operation (AECOO) industry traditionally exchange building models as files. The Building Information Modelling (BIM) methodology advocates the seamless exchange of all information between related stakeholders using digital technologies. The ultimate evolution of the methodology, BIM Maturity Level 3, envisions interoperable, distributed, web-based, interdisciplinary information exchange among stakeholders across the life-cycle of buildings. The World Wide Web Consortium Linked Building Data Community Group (W3C LBD-CG) hypothesises that the Linked Data models and best practices can be leveraged to achieve this vision in modern web-based applications. In this paper, we introduce the Building Topology Ontology (BOT) as a core vocabulary to this approach. It provides a high-level description of the topology of buildings including storeys and spaces, the building elements they contain, and their web-friendly 3D models. We describe how existing applications produce and consume datasets combining BOT with other ontologies that describe product catalogues, sensor observations, or Internet of Things (IoT) devices effectively implementing BIM Maturity Level 3. We evaluate our approach by exporting and querying three real-life large building models.

Internet-of-Things (IoT) focuses on enabling communication between all devices, things that are existent in real life or that are virtual. Building Information Models (BIMs) and Building Information Modelling is a hype that has been the buzzword of the construction industry for last 15 years. BIMs emerged as a result of a push by the software companies, to tackle the problems of inefficient information exchange between different software and to enable true interoperability. In BIM approach most up-to-date an accurate models of a building are stored in shared central databases during the design and the construction of a project and at post-construction stages. GIS based city monitoring / city management applications require the fusion of information acquired from multiple resources, BIMs, City Models and Sensors. This paper focuses on providing a method for facilitating the GIS based fusion of information residing in digital building “Models” and information acquired from the city objects i.e. “Things”. Once this information fusion is accomplished, many fields ranging from Emergency Response, Urban Surveillance, Urban Monitoring to Smart Buildings will have potential benefits.

Purpose – The next generation of Building Information Modelling (BIM) seeks to establish the concept of Building Knowledge Modelling (BKM). The current BIM applications in construction, including those for asset management, have been mainly used to ensure consistent information exchange among the stakeholders. However, BKM needs to utilise knowledge management (KM) techniques into building models to advance the use of these systems. The purpose of this paper is to develop an integrated system to capture, retrieve, and manage information/knowledge for one of the key operations of asset management: building maintenance (BM). Design/methodology/approach – The proposed system consists of two modules; BIM module to capture relevant information and case-based reasoning (CBR) module to capture the operational knowledge of maintenance activities. The structure of the CBR module was based on analysis of a number of interviews and case studies conducted with professionals working in public BM departments. This paper discusses the development of the CBR module and its integration with the BIM module. The case retaining function of the developed system identifies the information/knowledge relevant to maintenance cases and pursues the related affected building elements by these cases. Findings – The paper concludes that CBR as a tool for KM can improve the performance of BIM models. Originality/value – As the research in BKM is still relatively immature, this research takes an advanced step by incorporating the intelligent functions of knowledge systems into BIM-based systems which helps the transformation from the conventional BIM to BKM.

Purpose – Construction organisations are mandated to use Building Information Modelling (BIM) for Government projects from 2016. The purpose of this paper is to investigate the current status of the management aspects of BIM. Design/methodology/approach – Following a telephone sift, a web-based questionnaire was conducted with UK construction BIM experts with 92 responses. Findings – This research demonstrates a paradigm shift in construction as operations were deemed more important than the technical aspects of BIM Adoption. Respondents agree with enforced Level 2 BIM, demonstrating client demand is a significant driver on uptake. BIM use will substantially increase in the next five years. Ranking of the importance of current BIM standards indicated BS1192 was most used but almost a third adopted individual standards producing fragmentation. BIM’s effect on consultant fees indicated the need for structural change. Practical implications – Front end design via BIM models and clash detection outweighed the use for facilities management indicating industry were meeting the target but not exploiting BIM to its full potential. Design and build and framework arrangements were the most common BIM procurement routes. Fragmentation of standards use creates a future interoperability problem between BIM systems. Social implications – Design team structure changes are supported with the adoption of a separate BIM manager being popular. Analysis of industry-wide model hosting characteristics indicated individual disciplines managed their own models meaning without an additional target for Level 3 BIM the single model environment is unlikely to be widely adopted. Originality/value – BIM fee structure and procurement are investigated for the first time

<p><strong>Abstract.</strong> Rapid urbanisation relates to increased space requirements above and below ground and the development of complex structures. This profound need attracted increasing interest for the collection, modelling, management, visualisation and dissemination of 3D objects through various application fields, such as: 3D Cadastre, 3D City Modelling and Building Information Modelling. Contemporary advances in GIS technology, Geo-Web services and computer graphics facilitate the development of such models accompanied by semantic, geometrical and topological information, while the use of international standards enables the communication and interoperability between the systems. The aim of this paper is to combine state-of-the art methodologies and technologies for the development of semantically enriched 3D models for the Campus of the National Technical University of Athens in Greece. The result is a web-based 3D Campus map that integrates these models as Web Services, providing access to management and navigation for the campus area and can also be used for maintenance purposes from the various NTUA Departments. To this end, the database schema has been designed compatible with CityGML, while attention was given to interoperability issues that arise from differently derived 3D models which had to be stored and visualised while retaining their characteristics.</p>

Operations and maintenance (O&M) management for existing buildings is of high importance since it consumes the most cost during buildings’ lifecycle. Its effectiveness could be significantly improved through the systematic use of building information modeling (BIM). However, BIM relies on full-fledged digital models, which, for most buildings, are not available. This paper introduces a recognition algorithm aiming at the automatic generation of 3D building models from 2D drawings. The algorithm is able to generate separated wall segment 3D models with their topology relations. The algorithm is implemented and tested by several real projects. The results are very promising and show that the proposed algorithm could be a key component of future digital toolkits for O&M management.

Aiming at the large amount of component data in the 3D dynamic display of the ancient building BIM model, which caused difficulties in information exchange during the protection of the ancient building, a lightweight method of the ancient building BIM model combining with WebGL and IFC standards was proposed. Using WebGL technology to extend the 3D visualization method of BIM models of ancient buildings, providing new technical support for the protection and research of ancient buildings. First define the JSON intermediate file, design the Revit-JSON data interface, make the model support .html and .js format, and improve the visual display method of the web side; use JavaScript to directly call the JSON interactive program of the underlying GPU to improve the web-side rendering effect of the model; Three.js framework realizes the display and interaction of 3D models of ancient buildings on the Web. Taking a typical ancient building as an example to carry out experiments, the method in this paper can reduce the storage volume by more than 70% on the basis of ensuring that the model information is complete, and has a good rendering effect in the browser. The experimental results verify the effectiveness and feasibility of the method.

This work presents the developments of representing a part of the city districts of Manchester, UK and Turin, IT initiated within the FP7 DIMMER project completed in 2016 and continued in the last years by the Center of Excellence GIS of CSI Piemonte. The DIMMER system integrates BIM (building information modelling) and district level 3D models with real-time data from sensors and user feedback to analyze and correlate buildings utilization and provide real-time feedback about energy-related behaviors. The emerging standard 3D Tiles endorsed by the OGC was applied to represent CityGML data of two districts of Turin, Italy and Manchester, UK. 3D Tiles allows for a high level of detail (LOD) visualization that displays increasing detail of geometric features and their alphanumeric properties. Currently, the OGC 3D Tiles technology is mature, and the OGC CityGML specification will be soon updated to version three, with the adoption of exciting innovations like the support of time-dependent properties defined Dynamizers.

Information Interchange

Buildings have a multifunctional character, which makes it hard to define just one model for all their diverse functions. As these diverse functions are addressed by actors of different perspectives and domain backgrounds, the possibility to exchange available building information would be desirable. Two main models for the creation of building information are Industry Foundation Classes/Building Information Modelling (IFC/BIM) and City Geography Markup Language (CityGML). As the importance of information interchange has been recognized, several authors have tried to develop intermediate models for the information exchange between IFC/BIM and CityGML, e.g., the Unified Building Model (UBM), the BIM Oriented Indoor data Model (BO-IDM), the Indoor Emergency Spatial Model (IESM) and the BIM-GIS integration model for Flood Damage Assessment (FDA model). Nevertheless, all these models have been created with a certain use in mind. Our focus in this article is to identify common elements amongst these proposed models and to combine them into one “core model” that is as simple as possible, while simultaneously containing all important elements. Furthermore, this base model extracted from proposed intermediate models can then be expanded to serve specific use requirements, while still being exchangeable. To show this cross-domain character of the core model, we validated the resulting model with two cases of use (production environment/maintenance and 3D digital cadaster).

The report presents the author’s experience in integrating modern ICT technologies in the process of teaching and learning in school. The emphasis is on the use of mobile devices and the integration of cloud technologies in schools. As an ICT teacher, the author provides some practical guidelines on how to apply innovation. The generation of 7 screens does not know a world without digital technologies and mobile communications. The discrepancy between the expectations of the digital generation and the reality in our schools is in terms of the information and communication technologies (ICT) used in them and the didactic models. Adolescents, when they find themselves in an environment that does not meet their expectations, are demotivated and redirect their attention to other objects and goals and stop being active in class. The use of the so-called. „Cloud“ technologies will significantly increase the interest and retention of students. The modern approach to building information systems is focused on developing solutions in which the collection, input and output of information is carried out through WEB-based applications or platforms.
