Virtual reality technology applied in engineering education

Abstract: The three-dimensional geometric models used to present architectural and engineering work, show only the final form, which does not allow progress in constructions to be observed. But, the visual simulation of the construc-tion process of a building need mod-els which are able to produce dynamic changes to their geometry. This paper re-ports how techniques of geometric modelling and virtual reality were used to obtain models that could show their physical evolution over time and which would be able to simulate construction processes visually. Two types of work, concerning the construction of a cavity wall and a bridge, were developed as virtual models for educational purposes. These models make it possible to view the physical evolution of the work, to follow the planned construction sequence, to visualize details of the form of every component of each work and to support the study of the type and method of op-eration of the equip-ment necessary in the construction process. These models have been used to distinct advantage as educational aids in first-degree courses in Civil Engineering. The use of virtual reality techniques in the development of educational applications brings new perspectives to the teaching of subjects related to the field of construction.

The importance of engaging engineering and construction learners in virtual worlds and serious games

Abstract: The engineering and construction industries require their workforce to undertake complex learning and training activities. Exposing new employees, graduates, or apprentices to these environments could endanger their safety and the safety of those working with them. On site education and training also requires an investment of time from skilled individuals and companies. Problems accessing environments, such as construction sites, heavy plants or chemical manufacturers, are substantially heightened by the need to risk assess and comply with Health and Safety legislation making the traditional “hands on” and “shadowing” approaches to training and education more complicated than in the past. These difficulties are also compounded by changes to the geographical locations (e.g. distance learning, on site) of those studying to join these career paths or progress within them. Therefore, educational institutions and trainers must consider how to deliver this skill based learning for both those with access to academic premises and those learning at a distance. New technologies such as serious games are one of the solutions being explored. This paper undertakes an analysis of safety issues and safety training and learning methods relating to the construction industry. The paper takes its start point from a Health and Safety Executive commissioned report in 2003 (Hide et al, 2003) and questions if sufficient improvements in safety have been achieved within the construction industry since its publication. Then, the paper investigates the development of education and training that meets the necessary reality and complexity of engineering and construction sectors and the ability of serious games to provide timely and accessible training to achieve competency within these sectors.

The development of an integrated life cycle costing model using object oriented and vr technologies

Abstract: There is an increasing realisation of the importance of operation and maintenance as opposed to capital costs throughout the life of an asset. In addition, new styles of contracts such as PFI (Private Finance Initiative) are becoming more popular. This will require that the building product is addressed within its holistic picture including the design, construction and maintenance. It is therefore vital to embed the life cycle costing element of a facility within its design and construction. Whole Life Costing is a technique used to facilitate effective choice between alternatives in the search of economic solutions. Information technology, particularly integrated databases and VR (Virtual Reality), can provide the mechanism to facilitate the integration of the whole life cost information. The research project described in this paper aims to add a life cycle costing element to the design phase of the OSCON integrated database developed at Salford University in the UK. The current integrated database within OSCON supports the functions of design, estimating and planning. The proposed system will allow the user within a VR environment to navigate inside the building retrieving information about building components that need replacement or repair. A colouring mechanism will be developed to show various elements in different colours according to cost criteria. This would allow the user to easily inspect the building and get rough ideas of repair and maintenance programmes, running costs and cash flows. The system will allow data to be updated continuously so that it will enable the comparison with initial plans and estimates and provides a fresh view of future action and feedback.

Information technology teaching at the University: an experience at the Faculty of Architecture in Naples

Abstract: The experiences illustrated here refer to didactic activity carried out at the Faculty of Architecture of the University of Naples; in particular these concentrate on the technological aspects of the teaching of architecture. We can consider the evolution of the architect from individual operator to manager of the multi-disciplinary aspects of the building process (building process manager) as a reality in today's Italy. The Support Systems of Information Technology (ITSS), can be of great importance €or this professional figure, and for this reason it is important to include him/her in the teaching process. I personally have involved fourth and fifth year and last-year undergraduate students in the following subjects at the experimental stage: degradation diagnosis supported by m Expert System in courses of the Technology of Building Rehabilitation; co-ordinated System of tests in degradation of existing buildings; the use of three-dimensional programmes to survey and visualize rhe territory; rapid analysis of degradation in the maintenance of urban facades. * In these and other similar works I'TSS has played a significant part for a global synthesis in students' methodological approaches, being an inttoduc tion to new Information Technology potentialities.

Cognition Enhancement Using Virtual Reality in Apartment Customization

Abstract: The design and construction of customer configured apartments is challenging when customers are unable to interpret construction drawings or lack the knowledge or competence to deliver the decisions and information that is required from them. Builders dedicate significant managerial and technological effort to manage the customization process with their customers, and this process is commonly recognized to be inefficient. Studies suggest that one root cause is the fact that most customers are not construction professionals, hence decision making is often a challenging and sometimes unpleasant task for them due to insufficient product cognition. In this study we developed a virtual reality tool for the facilitation of an immersive presentation of yet to be built apartments to customers, speculating that cognition may be enhanced and facilitate the customization decisions. An experiment was conducted to identify and measure cognition differences. Some areas of measured cognition shown noticeable improvement which imply for significant cognition enhancement. Exploitation of the findings by future adoption of the examined method is discussed and suggested to construction companies.

Misconceptions About Integrated Project Databases

Abstract: The notion of an integrated project database (IPDB) has existed for decades. Over that time many projects have been undertaken to develop the technologies and frameworks required to implement an IPDB. Also over that time, there has been promotion of the benefits and impacts that IPDB systems will have on the industry. As there are still no industrially stable IPDB systems in existence, the industry's perception of what they are and what they can do has diverged from many of the original presentations. It is also clear that researchers and de-velopers involved in IPDB development have many different ideas about what constitutes an IPDB and what is, or is not, possible to create. This paper aims to describe misconceptions which are growing up around IPDB systems, and presents the authors' view of reality (informed by the opinions of the UK network of experts in ob-jects and integration (URL-1 1999) which was run by the DETR).

Developing a Campus Wide Building Information System Based on Open Standards

Abstract: University campuses can significantly benefit from IoT technologies, especially from operational efficiencies and user experience perspective. Traditionally, such systems have been limited to lab based environments, where involvement of end-users is limited and the results may not reflect reality. To build IoT systems for real-world that are reliable and relevant, it is important to build experiments in real-world conditions and involve end-users. From technological perspective, there is a need for convergence of diverse fields ranging from Building Information Systems and Building Services to Building Automation Systems, IoT devices and finally the campus services that include academic and research activities.This paper outlines the efforts to develop a campus wide web based system called Otaniemi3D that provides information about energy usage, occupancy and user comfort by integrating Building Information Models and IoT devices through open messaging standards (O-MI and O-DF) and IFC models. The paper describes the design criteria and the system architecture and the workflow to generate the information needed to develop such a system.
