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.

Examples of product model transformations in construction

Abstract: This paper discusses the results of a case study of product model transformations and geometric reasoning techniques for a challenging project. The complex geometry in the Experience Music Project offers unique challenges in construction processes. Manual transformation of the design-centric product model prepared by the architect into a production model for construction is time-consuming. We discuss ways to transform a design view of a product model into a construction view emphasizing the value of product models supporting multiple views. Geometric reasoning aids in the planning, scheduling, coordination of the project, and modeling of temporary structures. We are developing methods to support these product model transformations using the geometric model.

The Nature of Managing IT and Its Managerial Challenges

Abstract: Management of information technology (IT) is increasingly important for organizations and users at the work environment. This paper, first, introduces the way IT is changing the work environment. Second, failure to integrate IT, building systems and the work environment is addressed as a result of the subdivision of responsibility by professional discipline and poor communications in team decision-making. Third, this paper describes the nature of managing IT, which is a life-cycle activity and a problem-solving business. Furthermore, managing IT requires multi-disciplinary participation in the delivery process. Finally, four managerial challenges are provided for all professions in the field, including to assess what the users need, plan for better systems integration, manage the project delivery process effectively, and use computer aids for education and training.

Towards ICT-enhanced management support systems for optimizing infrastructure procurement

Abstract: Infrastructure procurement programmes of many public clients and large private developers, increasingly involve complex networks of stakeholders. Well balanced and 'fully informed? decisions are critical in optimizing resources to achieve agreed objectives. A research project in Hong Kong is aimed at developing an ICT (Information and Communications Technology) - enhanced MSS (Management Support System). This will empower the formulation of more effective and efficient construction project procurement and delivery/ operational systems - for innovative and improved 'total? management of construction projects - from a large client's viewpoint. Web-based Decision Support Systems (wDSSs) are being developed to help achieve such objectives, by capturing, codifying and mobilising both expert and experiential construction industry knowledge. Furthermore, web interfaces are being designed to mobilise the collective expertise of the entire project supply chain in real-time collaborative formats. These decision aids will enable the often fragmented multi-disciplinary project teams to build on 'state of the science? knowledge, past 'lessons learnt? and present best practices, in making more informed managerial decisions that will help to optimise inputs and reduce wasted resources. Potential benefits of wDSSs are demonstrated in this paper, through examples from the integrated framework and prototype modules/ models that are under development and 'construction' in Hong Kong. These cover a crosssection of infrastructure programme management decision scenarios, i.e. in: (1) multi-purpose contractor registration-prequalification, (2) dynamic performance appraisal of contractors and (3) evaluating 'extension of time? entitlements. Interim outcomes included herein are the basic MSS framework, pilot models of items (1) and (2) above and prototype modules of item (3) above.

Architectural computer-aided design systems: an example

Abstract: In 1987, a project was initiated at The IMS Design Research Workshop with the aim to study the effects of the introduction of CAAD methodology on the possible qualitative improvement of architectural design in the Institute's proprietary Building System " GIMS". The system consists of a precast prestressed concrete skeleton structure that incorporates various sub-systems, and has been applied extensively in housing and public building in Yugoslavia and many other countries. Generally speaking, all well-defined and well-structured aspects of architectural design, mainly dealing with the technical aspects and/or graphical presentations, have been successfully modelled and merged with thecomputer application and applied particularly in the detailed design phases. This is not so with the ill-structured problems and fluid situations that dominate the conceptual phase. Many decisions here depend on the subjective judgements of the designer. Knowledge-based systems have been applied in the selected domains to aid decisions based on experience and difficult to model by algorithmic methods. However, how to increase quality of design process is an open-ended question. The semantic aspects of design have not been treated to a great extent in CAAD research projects so far. The paper describes some of the project results - the CAAD methods and tools to be used as aids in conceptual design of the IMS family houses. The tools have been developed to a prototype level, with limited, but adequate testing of their performance.The present versions are applicable on the IBM personal computers.

Assessing the pedagogical value of Augmented Reality-based learning in construction engineering

Abstract: This paper presents the latest findings of authorsí work in design and assessment of an augmented reality pedagogical tool for construction engineering education. Previous work has extensively discussed the need for suitable learning tools and information delivery methods to enhance the quality of engineering education. However, developing a methodology with measurable outcomes that can assist in transforming conventional instructional techniques is not a trivial task and requires a meticulous approach. Within the educational research community, it is commonly accepted that instrumental aids, if properly used, can be effective controllers of human learning. This prospect coupled with the fact that technological advancements and mobile tools have become ubiquitous parts of our lives, motivated the authors to explore the possibility of using smartphones and tablet devices as instrumental aids to improve the quality of classroom teaching and learning. In particular, a context-aware augmented reality application was used to create a pop-up book by superimposing 3D graphics (virtual models, animations) and multimedia (images, videos, sounds) over the pages of a construction engineering textbook. This enabled students to watch, interact with, and learn abstract topics in construction equipment and methods in multiple contexts. The hypothesis of this research is that by establishing a contextual connection between ordinary textbook materials and technologies that students use in their daily routines, student engagement in the learning process improves, students can focus their attention to critical concepts, and instructors will be able to better evaluate studentsí progress toward conceptual understanding. In this regard, effectively measuring knowledge transfer and metacognition plays a vital role. To achieve this, several assessment techniques such as teacher-designed feedback forms, group-work evaluations, pre- and post- surveys, and exam evaluations are used to assess all three aspects of the learning process (replicative, applicative, and interpretive). Results, technical discussions, and recommendations are provided in this paper.
