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.

Interactive Map

Modern people can use navigation on the outside to save time and get to the destination well. Likewise, in order to find out more information about a destination building, such a system is increasingly needed both in front of the computer (on-line) of the house and after reaching the destination in the building (off-line). Accordingly, we employ Building Information System (BIS) as a system that provide users with content related to a building like BIO and BIM. The Building Information Online system (BIO) is an interactive map application designed to assist customers in finding parcels and building on a map online. The Building Information Modeling (BIM) allows nD information to be visualized simultaneously by architects, engineers and constructors to gain a synchronized understanding viewing from different perspectives. Inspired by above researches, we implement a service that provides online and offline Virtual Reality (VR) and Augmented Reality (AR) content for a building. This system can provide users outside the building with information within the building via devices with VR and AR support regardless of space restrictions. The system is designed to operate across scenarios requiring offline, online, offline-online collaboration, etc., and the corresponding experiments are carried out.

In an educational perspective, unlike other disciplines, hands-on practice is difficult to come by in Civil Engineering. By providing a student with a realistic 3D simulation, we propose a concept that improves the understanding of the individual and eliminate guess-work entirely. Our platform that makes education fun and interactive by eliminating the constraints of a conventional teaching environment by incorporating Virtual Reality (VR) or Augmented Reality (AR) as a tool. AR can help the target audience visualize a model (to scale) in all three dimensions in the palm of their hand. This chapter explores the use of interactive 3D game environments in design visualization in Building Information Modeling (BIM) by adopting various available software packages and APIs. VR will allow the prospective customer to enter and explore a structure before it is constructed. This can be achieved by making use of a powerful game engine, in this case, Unity3D. In this chapter, we will describe ways to pivot Unity's functions towards the benefit of civil engineering.

PurposeThis research proposes a virtual reality (VR) platform for construction detailing that provides experiential learning in a zero-risk environment. It builds on integrating VR technology as a medium and building information modeling (BIM) as a repository of information and a learning tool.Design/methodology/approachThis work discusses the proposed environment curricular unit prototype design, implementation and validation. The validation of the VR environment was conducted in three phases, namely, piloting, testing (system usability and immersion) and learning gain validation, each of which has its aim and outcomes and has been assessed both qualitatively and quantitatively.FindingsAfter considering the feedback, the VR environment prototype is then validated on the level of learning outcomes, providing the evidence that it would enhance students' engagement, motivation and achievement accordingly. The results indicated 30% learning progress after experiencing the VR environment vs. 13.8% for paper-based studying.Originality/valueIn reference to building construction education, construction site visits provide students with real-life practical experience which are considered an extension for classroom. Nevertheless, it is challenging to integrate construction site visits regularly during the academic semester with respect to the class specific needs. The research at hand adopts integrating VR and BIM in AEC (Architecture, Engineering and Construction) education by proposing a system that can work as a mainstream complementary construction detailing learning method for architecture students. The proposed VR system facilitates a virtual construction site that meets the learning needs where students can explore and build in a real scale environment.

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.

Engineering Modeling

The growing need to recover and digitally represent heritage infrastructure has led to the challenge of choosing different Building Information Modeling (BIM) platforms that will be used to manage the implementation of the semi-automatic design and reconstruction processes of reverse engineering modeling. The approach to the integrated management of information derived through Heritage-BIM (H-BIM) has been applied to Via del Duomo, one of the main roads in the old town of Naples, Italy. During preliminary inspections of the construction site it was possible to acquire geometric features and pavement/subgrade information, as well as to conduct a photographic survey, with 1,618 photographs collected. Subsequently, the acquired data were processed, using different BIM-based tools, to obtain the 3D mesh; objects were then converted from pure graphic solids into parametric entities by proposing a specific algorithm. Then a library, with the inclusion of all the possible stone paving package alternatives, including all the structural and stress-deforming characteristics such as Young Modulus (E), Poisson coefficient (n), and Safety factor (SF), was created. In this way, it is possible to associate to the generic element the optimal pavement package solution, depending on different construction contexts. As preliminary result, a dynamic model that updates its information package and modifies the output of the analysis every time the data worksheet is integrated with new collected results is proposed for further pavement management operations evaluation.

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.
