Abstract Building information modeling provides an integrated three-dimensional environment applied to the management of large-scale engineering projects, allowing you to reduce the cost and time for planning structures and requirements for the reliability of buildings. The purpose of this work is to develop a methodology for changing the layout and reliability factor during the visualization of three-dimensional models to improve the analysis of building plans. This approach will allow you to combine different analytical methods and approaches when planning different structures. The results of this work suggest new directions for future research in the field of information visualization for the construction complex. The system is compatible with portable and scalable mobile devices. The proposed system can also be used for pre-project architecture and augmented visualization, where proprietary developed methods are used to achieve the quality of photorealistic rendering.

With application and popularization of information modeling technology, both Geographic Information Systems (GIS) and Building Information Modeling (BIM) could represent three dimensional models in different fields. By introducing application features of GIS and BIM in Metro construction, this paper presents such a thought that effective combination of GIS and BIM may play a role at different stages in metro construction.

In the past two decades, building information modeling (BIM) has been widely adopted by architectural, engineering, and construction firms. Its technology is based on the integration and coordination of different disciplines and professions. It involves creating three-dimensional models containing data that can be organized and manipulated to serve design, construction, and operational phases. This raises the debate over how the existence of a platform that enables urban planners and decision makers of different disciplines is so crucial. Several research studies have recently been done to integrate BIM with geographic information systems (GIS) for numerous purposes, as illustrated by several case studies. This chapter comparatively analyzes different cases, given general acknowledgment of each. Problems and potentials of the existence of such integration will be defined, in order to estimate the need for such a platform. Finally, a model of integration between different disciplines was illustrated as a motivation for further studies in the future concerning this topic.

<p><strong>Abstract.</strong> The developments of the latest technology in the field of Digital Cultural Heritage (DCH) are revolutionizing the methods of surveying, representing and managing the built heritage. The integrated use of 3D survey instruments such as laser scanning, digital photogrammetry and the new holistic way to represent the architecture, based on the Building Information Modeling (BIM), allows the collection, analysis and archiving of a large amount of data, by increasing information sharing among a great number of experts involved during the life cycle of the building. The paper focuses on the connection between Italy and Czech in terms of vaults patterns and construction techniques. The two case studies are the frame vault of the chapel of the Italian Cultural Institute and the barrel vault with lunettes of the Klementinum Baroque Library. They are both unique examples of the great expertise of architects and craftsmen that worked in Bohemia across the 17th and 18th centuries. Most of them were from the North of Italy, like the ones that worked in the building sites of the two case studies. The in-depth study of the construction techniques and the complex shapes needs the use of new scan-to-BIM modeling requirements, based on the definition of geometric primitives useful for the generation of intelligent three-dimensional models able to integrate different types of data. Finally, the acquired data are included in a database that collects information coming from both Italian and Czech studies, raising awareness among citizens of the richness of their built heritage.</p>

<p>This article aims to critically examine the entire methodology of very large scale (1:1) surveying and documentation of mosaic surfaces. The term ‘survey’ should be read in its broadest and most complete and sense, including the phases of measurement and data processing as well as management and use of these data for the purposes of preservation and maintenance. The case study presented here took place at St Mark’s Basilica (<em>Basilica di San Marco</em>), in Venice, where mosaic flooring, wall and vault decorations have been surveyed on two separate occasions. These two experiences shared a common goal (a full-scale survey of the mosaic decorations) but differed in terms of the methodologies used, chiefly due to the technological developments of recent years. All this, therefore, lends itself to a methodological reflection and critique of the ways in which surveying technology has evolved over time. It enables to conduct surveys that would, just a few years ago, have been inconceivable due to their size and complexity. This article describes in detail current surveying processes, which includes the use of a multi-scale “image-based” approach, “re-topology” methods such as non-uniform rational B-spline (NURBS) and a tailor-made Building Information Modeling (BIM) system. This system allows the direct use of a three-dimensional (3D) model of the Basilica within the maintenance process of the monument itself with the options to georeferencing information, extract basic metric data and catalogue all its mosaics.</p><p><strong>Highlights:</strong></p><ul><li><p>Modern digital photogrammetric techniques enable the acquisition of very complex objects, not only in terms of form but also in terms of material.</p></li><li><p>To obtain high resolution orthophotos, it is necessary to accurately take care of all the stages of the process: photographic acquisition, surveying, modelling and orthographic reprojection.</p></li><li><p>High resolution images and detailed 3D models can benefit from a complex BIM system for the management of all data.</p></li></ul>

The building sector influences the Gross Domestic Product (GDP) of many countries. There is a vast amount of waste generated in the building process, with many projects suffering from delivery delays, running over budget, and resulting in buildings of minimal quality. Building Information Modeling (BIM) has shown great potential towards solving these problems. BIM sets frameworks for Architects, Engineers, and Contractors (AEC), enhancing management of the building process. This paper analyzes select framework methods, tools, and processes, identifying key guidelines required to create a BIM framework customized to local requirements; this will have a positive effect on the construction industry by lowering the cost of buildings and improving the communication among parties, and leading to the development of frameworks based on local indicators. A comprehensive literature review was conducted to determine components and factors from structure frameworks with the main findings then classified and categorized into the following sectors -- government support, maturity level measurement, standards, protocol, database, and education plan. This permits the development of a comparison highlighting the frameworks’ differences and summing up possible strategies for BIM implementation on several bases, such as region differentiation and the local industries’ Political, Economic, Socio-Cultural, Technological (PEST) aspects, allowing for greater understanding of BIM implementation on various scales. The selection of the BIM frameworks was dependent on specific criteria with a minimum score of 4 out of 5 required to merit inclusion. Three strategies for the creation of a BIM framework were discovered and were seen to vary across regions. The discovery of these strategies lays the groundwork for future research into the development of these frameworks to determine the potential advantages and downsides of each.

AbstractIn the last few years, particular focus has been devoted to the life cycle performance of fastening systems, which is reflected in increasing numbers of publications, standards and large-scale research efforts. Simultaneously, experience shows that in many cases, where fastening systems are implemented – such as industrial facilities – the design of fasteners is governed by fatigue loading under dynamic characteristics. In order to perform an adequate design and to specify the most efficient and appropriate fastening product, the engineer needs to access and process a broad range of technical and commercial information. Building information modelling (BIM), as a data management method in the construction industry, can supply such information and accommodate a comprehensive design and specification process. Furthermore, the application of BIM-based processes, such as the generation of a BIM-model, allows to use the important information for the construction as well as the life cycle management with different actions and time dependencies of the asset and its components. As a consequence, the BIM model offers the potential to correlate different data relevant for achieving the goals of the respective application, in order to ensure a more effective and correct design of the fastening. This paper demonstrates such a BIM-based design framework for an Industry 4.0 case, and in particular, the installation of a factory robot through post-installed anchors under fatigue-relevant loading in concrete.

The latest developments in the field of generative modeling and building information modeling for heritage building (HBIM) have allowed the authors to increase the level of transmissibility of information through the most modern techniques of virtual and augmented reality (VR-AR). This chapter summarises the last years of applied research in the field of three-dimensional modeling oriented to digitise and correctly represent the built heritage thanks to the integration of the most modern three-dimensional survey techniques with a scan-to-BIM process based on new grades of generation (GOG) and accuracy (GOA). The new paradigm of the complexity of the built heritage, its tangible and intangible values, have been shared through new immersive ways able to increase the information contents and the knowledge accumulated in the last years of one of the most representative and unique buildings of the Lombard architecture: the Cà Granda in Milan.

This work represents a paradigm shift in the approach to manage port infrastructure maintenance where the use of the building information modeling (BIM) method is very scarce, and it is now beginning. The new infrastructure conservation management method proposed in this manuscript combines traditional methods with new technology, covering the gap of the implementation of BIM in port maintenance. This new technology is the BIM method, and its use is already mandatory in public infrastructure projects in some countries. In this work, the BIM method is applied to the management of the conservation of port infrastructures to show the benefits that can be obtained using it. After the analysis of the state of the art in the conservation of port infrastructures, two of the main maritime works of the Outer Port of A Coruña were modeled in Revit. This as-built model serves as an inventory model and forms a large database of all the information regarding the conservation of the structures. In this way, all the data on the conservation of the port’s infrastructures are concentrated in a single source of information in which, in addition, there is a three-dimensional and georeferenced representation of the port in question. The main finding of this work is the development of a step by step method to implement BIM philosophy in port maintenance, highlighting the positive and negative points detected during the validation of the method in a real case, detecting future improvement research lines. Although BIM has a lot of advantages and possibilities just now, some improvements are still necessary.

Objectives:This study aims to provide the first estimates of the costs and effects of the large scale introduction of autologous transfusion technologies into the United Kingdom National Health Service.Methods:A model was constructed to allow disparate data sources to be combined to produce estimates of the scale, costs, and effects of introducing four interventions. The interventions considered were preparing patients for surgery (PPS) clinics, preoperative autologous donation (PAD), intraoperative cell salvage (ICS), and postoperative cell salvage (PoCS).Results:The key determinants of cost per operation are the anticipated level of reductions in blood use, the mean level of blood use, mean length of stay, and the cost of the technology. The results show the potential for considerable reductions in blood use. The greatest reductions are anticipated to be through the use of PPS and ICS. Vascular surgery, transplant surgery, and cardiothoracic surgery appear to be the specialties that will benefit most from the technologies.Conclusions:Several simplifications were used in the production of these estimates; consequently, caution should be used in their interpretation and use. Despite the drawbacks in the methods used in the study, the model shows the scale of the issue, the importance of gathering better data, and the form that data must take. Such preliminary modeling exercises are essential for rational policy development and to direct future research and discussion among stakeholders.

Abstract Does ethnic stacking in the armed forces help prevent military defection? Recent research, particularly in Africa and the Middle East, suggests so; by favoring in-groups, regimes can keep in-group soldiers loyal. In-group loyalty comes at the cost of antagonizing members of out-groups, but many regimes gladly run that risk. In this research note, we provide the first large-scale evidence on the impact of ethnic stacking on the incidence of military defection during uprisings from below, using data on fifty-seven popular uprisings in Africa since formal independence. We find clear evidence for the downside: ethnic stacking is associated with more frequent defection if out-group members are still dominant in the armed forces. We find more limited support for the hypothesized payoff. Ethnic stacking may reduce the risk of defection, but only in regimes without a recent history of coup attempts. Future research should therefore trace the solidification of ethnic stacking over time.
