Integration of virtual reality within the built environment curriculum

Virtual Reality (VR) technology is still perceived by many as being inaccessible and cost prohibitive with VR applications considered expensive to develop as well as challenging to operate. This paper reflects on current developments in VR technologies and describes an approach adopted for its phased integration into the academic curriculum of built environment students. The process and end results of implementing the integration are discussed and the paper illustrates the challenges of introducing VR, including the acceptance of the technology by academic staff and students, interest from industry, and issues pertaining to model development. It sets out to show that fairly sophisticated VR models can now be created by non-VR specialists using commercially available software and advocates that the implementation of VR will increase alongside industryis adoption of these tools and the emergence of a new generation of students with VR skills. The study shows that current VR technologies, if integrated appropriately within built environment academic programmes, demonstrate clear promise to provide a foundation for more widespread collaborative working environments

Improving Communication of Scheduling Information of Earthworks using 4D Visualisation Model in Road Projects

Innovative visualization technology applied to construction simulation and optimization has the potential to improve communications and coordination amongst the project stakeholders. In this context and in the drive for innovation in construction management, this paper introduces a framework of a 4D prototype for the automatic generation of visual terrain surfaces during earthwork construction processes. The framework has been designed and developed by integrating road design data, quantities of cut and fill, productivity models, algorithms for modelling terrain profiles and a road profile visualiser. The paper details the prototype of 4D visualization model (4DVM) that has been designed and developed in this research using innovative methodology where 4D models of terrain surfaces are generated based on coordinate data and the productivity of earthwork. The model has been demonstrated with a case study that was used to validate the model. The 4DVM is intended to assist project planners/construction managers in logical decision making processes for construction scheduling and resource planning. It will also improve the communication gap amongst the construction team and consequently improve site coordination and operation

A Review of Building Information Modeling and Simulation as Virtual Representations Under the Digital Twin Concept

Building Information Modeling (BIM) is a highly promising technique for achieving digitalization in the construction industry, widely used in modern construction projects for digitally representing facilities. Nevertheless, retains limitations in terms of representing construction operations. The digital twin concept may potentially overcome these limitations and initiate advanced digital transformation in the construction industry as it has revolutionized the product lifecycle management in the manufacturing industry. This research provides a critical review of applying digital twin in the construction industry. Altogether, 140 papers from related journals and databases were reviewed. The digital aspect of twinning consists of BIM and simulation modeling. These two techniques have been used to create virtual or digital representations of actual buildings and real-world construction processes. However, integrating and applying BIM and simulation modeling according to the digital twin concept remains to be fully studied. Comprehensive evaluations of BIM, simulation modeling, and digital twin will provide a well-defined framework for this research, to identify direction and potential for digital twin in the construction industry, thereby progressing to the next level of digitalization and improvement in construction management practice

Visualization of the modeled degradation of building flooring systems in building maintenance

The development of a maintenance programme for construction projects is a highly complex and data intensive undertaking. This exercise is characterised by the lack of relevant data on the one hand and the overwhelming amount of extraneous data on the other. The uncertainties and complexities have resulted in increased conservatism in the development of lifecycle evaluation of building maintenance programing, subsequently, these programmes tend to display the symptoms of either the maintenance actions being uneconomical or fall short of providing the appropriate service to the users of the building. The current research project is based on the premise that the visual approach will facilitate a just-in-time solution to maintenance scheduling, hence, the use of virtual simulation of the building is proposed. The broader aim of this research is to develop a complete building maintenance programme through visualisation of buildings as they degrade over time. Here, the focus is on the flooring system and the manner they degrade over time. This requires a better understanding of their pattern and rate of usage. To this end, Anthroposophy and Anthropocentric descriptions of human movement pattern have been used to describe the behaviour of 'subjects' and subsequently represent the pattern and density of the degradation of flooring systems. The mathematics representing this behaviour has been developed which enables it to be embedded into the proposed overall visual building maintenance model

Virtual reality for the built environment: A critical review of recent advances

This paper reviews the current state of the art for Virtual Reality (VR) and Virtual Environment (VE) applications in the field of the built environment. The review begins with a brief overview of technological components involved in enabling VR technology. A classification framework is developed to classify 150 journal papers in order to reveal the scholarly coverage of VR and VE from 2005 to 2011, inclusive. The classification framework summarizes achievements, established knowledge, research issues and challenges in the area. The framework is based on four layers of VR: concept and theory, implementation, evaluation and industrial adoption. These layers encompass architecture and design, urban planning and landscape, engineering, construction, facility management, lifecycle integration, training and education. This paper also discusses various representative VR research work in line with the classification framework. Finally the paper predicts future research trends in this area

Exploiting building information modeling throughout the whole lifecycle of construction projects

Over the past few years, construction industry has encountered numerous problems such as rework, design errors, accidents and building failure, time and economic losses, poor work efficiency, and low standard level of cooperation amongst team members of different sectors. As such, information communication technology (ICT) has been evolved to minimize all the aforementioned setbacks in the construction industry. In doing so, building information modeling (BIM) has been proposed to all construction members such as engineers, architects, contractors, and owners to take benefit from. Since BIM was emerged into the construction industry, it has received the attention of many researchers and practitioners. While there have been roughly numerous studies conducted on the benefits involved in the use of BIM, it is a unresolved point why there has not been a greater take up of exploiting BIM throughout the whole lifecycle of construction projects. Therefore, this paper is mainly aimed to examine the effectiveness of exploiting BIM throughout the three different phases of building’s lifecycle, including preconstruction, construction, and post construction in great details regarding the previous studies conducted in this field. The authors have concluded that utilization of BIM has several benefits in different stages of construction projects, including minimizing design error, reducing rework, increasing work efficiency and cooperation amongst team members, facilitating the process of delivery and procurement, and reusing the wastages of materials
