This study provides a review of important issues for ‘Building Information Modelling’ (BIM) tools and standards and comprehensive recommendations for their advancement and development that may improve BIM technologies and provide a basis for inter-operability, integration, model-based communication, and collaboration in building projects. The results embrace the requirements for a BIM research methodology, with an example of methods and procedures, an R&D review with critique, and a multi-standpoint framework for developments with concrete recommendations, supported by BIM metrics, upon which the progress of tools, models, and standards may be measured, evaluated, streamlined, and judged.

Building information modelling (BIM) has been a dominant topic in information technology in construction research since this memorable acronym replaced the boring “product modelling in construction” and the academic “conceptual modelling of buildings”. The ideal of having a complete, coherent, true digital representation of buildings has become a goal of scientific research, software development and industrial application. In this paper, the author asks and answers ten key questions about BIM, including what it is, how it will develop, how real are the promises and fears of BIM and what is its impact.

Over the last decade, building information models (BIM) have become increasingly popular. Yet their use on construction sites where the digital materializes, is limited. A technology that can bridge the gap between the digital and the real world is augmented reality (AR). We analyze this gap and the AR potential and present how the component based software engineering method can be used to efficiently implement a BIM-based AR system for construction. An architecture of the software system is proposed and verified by a prototype which was tested in a real construction project. We found out that the use of AR can significantly narrow the semantic gap between the digital model and the real world; that components for creating a BIM-based AR systems exist but currently do not scale well to large models; and that the use in AR applications creates additional requirements the for BIM models and tools, particularly related to the BIM's 4th dimension.

A path-following method that is based on controlling plastic dissipation or plastic work in an inelastic solid or structure is presented. It can be effective for highly nonlinear materially and geometrically problems. In particular, it can be applied for elasto-plastic problems where the standard arc-length methods fail, or to avoid artificial and undesirable elastic unloading of a complete solid or structure during the computation. The essential ingredients, the plastic dissipation and the plastic work based constraint equations, are derived by using either explicit or implicit pseudo-time step integration. These constraint equations are valid for geometrically nonlinear small strain elasto-plasticity with hardening. Their implementation in the framework of the path-following method is described. Several numerical examples are presented in order to illustrate very satisfying performance of the derived path-following method. It performed very well for some challenging shell problems.

A procedure for failure analysis of metal frames was derived. It is based on weak coupling of two nonlinear numerical structural models; the shell model (allowing for description of local buckling and localized material softening) and the beam model. Structural models are connected with one another through inelastic material models in a way that the beam material model includes effects of local buckling and softening.

The Internet has dramatically changed everyone's access to information, knowledge and other people. In many fields, this has resulted in an opening up of business models, products, services and organizations. Examples include open academic publishing, open software and open innovation. Experts are increasingly aware that a significant amount of knowledge and experience exists outside of their companies and institutions, which used to be the exclusive creator, aggregator and curator of knowledge and the sole places of innovation. Institutions are responding by reducing their boundaries and are opening up to the outside. A particularly potent technology for engaging people and capturing their knowledge has been social media. However, theories of participation and participatory approaches to shaping the built environment greatly predate even the Internet. In this paper, we present a conceptual framework for open and creative designing. A proven three-tier architecture, various theoretical levels of participation and an abstract view on social media tools have been used to develop an original, flexible, generative, “one size does not fit all” platform that can be used for the optimal collection of external information and knowledge. The platform allows for simple enhancement of in-house information systems (IS) with socially rich components. We are finding such a modular approach as very flexible for organizations that host the planning processes and that the application of social media technology creates very low barriers for the public to contribute.

The paper systematically builds an integrated model that includes quality as well as sustainable performance of the built environment and accompanying construction processes. This model for the “Integrated Quality and Sustainability Performance Assessment in Construction” presents a three-level arrangement, namely: the structure, process/ project, and construction product. In the present version, the model is tailored to the specific features of buildings, and the sustainability aspect is limited to the environmental performance. An investigation of measures required to implement the proposed model into practice shows that clients have a major influence upon the procurement rules. Consequently, the targeted audience of potential users is that of clients procuring buildings.

In many scientific and engineering areas there are emerging software services available over the Web. The reason for deploying such services in the Cloud is either to reduce the operational costs or to support the peaks in their usage profiles. The algorithms employed in such services are usually result of a long term research and technology development work, so it is beneficial to reuse those critical application parts when developing new Cloud applications. This paper investigates the possibilities to introduce a Model Driven Architecture (MDA) for the Cloud computing domain, which would support composition, customization, flexibility, maintenance and reusability of Cloud application components in the particular case of scientific and engineering applications. The underlying middleware technology of choice is the mOSAIC Platform as a Service (PaaS) solution. This choice is motivated by the fact that in mOSAIC a Cloud application consists of loosely coupled components, which are either generic and provide for key resource types needed by an application (computation, storage, communication) or custom made, e.g. based on existing legacy software. The MDA approach is illustrated through the design and operation of an application for analysis of structures under static loading. It is shown that a relatively simple design can be used to address two application bottlenecks: the varying number of users and the computational complexity of the given problem. The design reduces the necessary application development efforts and the key components can be reused for similar applications.

This study was conducted in twelve classrooms in Slovenia. in Groups were matched with respect to gender, ownership of a tablet computer and previous knowledge and understanding of maths. The instructional design of process-outcome strategies incorporated Bruner's (1966) three stage process with learning outcomes in the cognitive, affective-social and psychomotor domains. The affordance of tablet-based cross-curricular apps was examined with respect to domains of learning and ergonomics. The findings indicate that the tablet supported group had better outcomes, with a small effect size for conceptual knowledge (r = 0.10) and medium effect size for procedural knowledge (r = 0.33) and problem-solving abilities (r = 0.30).

The development of science is accompanied by growth of scholarly publications,primarily in the form of articles in peer-reviewed journals. Scientific work is often evaluated through the number of scientific publications in international journals and their citations. This article discusses the impact of open access (OA) on the number of citations for an institution from the field of civil engineering. We analyzed articles, published in 2007 in 14 international journals with IF, which are included in the JCR subject category "Civil Engineering". The influence of open access on the number of citations was analysed. The aim of our research was to determine, if open access articles from the field of civil engineering receivemore citations than non-open access articles. Based on the value of impact factor and ranking in quartiles, we also looked at the influence of therank of journals on the number of citations, separately for OA and NonOA articles, in databases Web of Science (WOS), Scopus and Google Scholar (GS). For 2026 studied articles we found out that 22 % of them were published as OA articles. They received 29 % of all citations in the observed period. This could be confirmed only partly for journals from the second quartile, and would not be confirmed for journals ranked into the third quartile. This showsthat open access is not a sufficient condition for citation, but increases the number of citations for articles published in journals with highimpact.
