AbstractWe describe a prototype system for communicating building information and models directly to on-site general contractors and subcontractors. The system, developed by SHoP Architects, consists of a workflow of pre-processing information within Revit, post-processing information outside of Revit, combining data flows inside of a custom application built on top of Unity Reflect, and delivering the information through a mobile application on site with an intuitive user interface. This system incorporates augmented reality in combination with a dashboard of documentation views categorized by building element.

The post-earthquake retrofitting and repair process of a building is a key factor in improving its seismic capability. A thorough understanding of retrofitting methods and processes will aid in repairing post-earthquake buildings and improving seismic resilience. This study aims to develop a visualization framework for the post-earthquake retrofitting of buildings which builds models based on building information modeling (BIM) and realizes visualization using augmented reality (AR). First, multi-level representation methods and coding criteria are used to process the models for a damaged member. Then, an information collection template is designed for integrating multi-dimensional information, such as damage information, retrofitting methods, technical solutions, and construction measures. Subsequently, a BIM model is presented in three dimensions (3D) using AR. Finally, the visualization process is tested through experiments, which demonstrate the feasibility of using the framework to visualize the post-earthquake retrofitting of a building.

Zusammenfassung Die Bauwirtschaft gehört bis dato zu den am wenigsten von der Digitalisierung erfassten Wirtschaftszweigen. Der vermehrte Einsatz von Building Information Modeling (BIM) in Planungsbüros beschleunigt nun die Digitalisierung des Bauwesens. Dies ermöglicht den vermehrten Einsatz weiterer digitaler Tools im Bauprozess, zum Beispiel Augmented Reality (AR). Neue Tools bieten die Chance, die vorhandenen Prozesse neu zu überdenken und auf Innovations- und Effizienzpotenzial zu untersuchen. Die Autoren sehen für die Technologie AR großes Potenzial im Bauprozess. Im Forschungsprojekt AR-AQ-Bau führten sie daher eine Anwendungs- und Anforderungsanalyse für AR durch. In diesem Artikel werden einige derzeitige und mögliche Anwendungen von AR im Bauwesen sowie deren Anforderungen an AR-Hard- und Software (z. B. durch die Besonderheiten der Baustelle) dargestellt und ein Ausblick in die Zukunft gegeben. Der Anwendungsbereich von AR ist äußerst vielfältig. Einerseits kann BIM dadurch leichter auf die Baustelle übertragen und können Abnahmen und Qualitätskontrollen durchgeführt werden. Andererseits stellen ein Remote-Expert-System, Schulungen und die Unterstützung im Behördenverfahren weitere Einsatzmöglichkeiten dar.

Heritage Building

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.

The Subject

Association rule mining is a data mining task that is applied in several real problems. However, due to the huge number of association rules that can be generated, the knowledge post-processing phase becomes very complex and challenging. There are several evaluation measures that can be used in this phase to assist users in finding interesting rules. These measures, which can be divided into data-driven (or objective measures) and user-driven (or subjective measures), are first discussed and then analyzed for their pros and cons. A new methodology that combines them, aiming to use the advantages of each kind of measure and to make user’s participation easier, is presented. In this way, data-driven measures can be used to select some potentially interesting rules for the user’s evaluation. These rules and the knowledge obtained during the evaluation can be used to calculate user-driven measures, which are used to aid the user in identifying interesting rules. In order to identify interesting rules that use our methodology, an approach is described, as well as an exploratory environment and a case study to show that the proposed methodology is feasible. Interesting results were obtained. In the end of the chapter tendencies related to the subject are discussed.

Defect management in civil construction work is crucial. This work is aimed at analyzing the conventional method of construction defect management and to bring out a framework for integrating 5D building information modeling with mixed reality. This work is divided into three parts. The first part is the integration of 5D building information modeling with augmented reality that helps to understand the architectural concepts and visualize the workflow onsite. The second part of the work is to develop a user-defined target-based marker-less augmented reality to send screenshots of augmented models and exact progress of work from construction site to engineers working in other locations. The third part of the work is to integrate virtual reality to enable virtual tours of the real site that will be useful for the customers to visualize the building virtually and for the builders to promote sales.
