Display and Rendering Technologies for Virtual and Mixed Reality Design Review.

Abstract: In this paper we introduce an innovative application designed to make collaborative design review in the architectural and automotive domain more effective. For this purpose we present a system architecture which combines a variety of visualization technologies such as high resolution multi-tile displays, TabletPCs and headmounted displays with innovative 2D and 3D Interaction Paradigms to better support collaborative mobile mixed reality design reviews. Our research and development is motivated by two user scenarios: architectural and automotive design review involving real users from Page\Park architects and FIAT Elasis. Our activities are supported by the EU IST project IMPROVE aimed at developing advanced display techniques, fostering activities in the areas of: optical see-through HMD development using unique OLED technology, marker-less optical tracking, mixed reality rendering, image calibration for large tiled displays, collaborative tablet-based and projection wall oriented interaction and stereoscopic video streaming for mobile users. The paper gives an overview of the targeted scenarios and focuses in particular on the rendering aspects of the project.

A web-based online postgraduate programme in project management

Abstract: The Department of Building and Real Estate of the Hong Kong Polytechnic University has recently developed and implemented a web-based online programme in project management. This programme meets the needs of professionals in the construction industry who wish to acquire new skills and insights as part of their continuing professional development without leaving their place of work for extended and/or repetitive periods. It allows such personnel to learn at their own pace in their own place, with faceto-face supporting workshops. Whereas academic staff members were responsible for the contents of subjects in the programme, a development team was formed to support them with the collection of content material, the development and transformation of the actual content, and instructional design advice on learning in the web-based environment, etc. This paper presents the experience of the team who has pursued the development of the programme into the realms of web-based distance learning. It describes the programme that has been developed, its successes, lessons learnt, and the overall theology that was developed for web-based learning for students of the programme. The opportunities for new methods of teaching and ways of presenting complex ideas are displayed. The use of technology to allow the introduction and innovative use of case studies and continuous monitoring of each student's performance are demonstrated.

Information Technologies and Information Requirements: A BIM-Based Approach

Abstract: The construction industry is currently facing important challenges: an imperative improvement of its productivity, higher performance targets and an increase of projects complexity. In order to overcome these challenges, a digital transition is on-going and has started with the implementation of Building Information Modelling (BIM) processes. At the same time, digitisation of the construction industry requires a paradigm shift focused on collaborative workflows and user involvement, with the Client acting as driver for innovation. The proposed paper highlights the role of the Briefing process as project management tool of the demand side of construction. Information technologies for managing the bi-directional link between as-briefed and as-designed information requirements within a BIM environment are also investigated. These approaches are then compared with the ones of other industries and particularly with Systems Engineering methods. As a major Systems Engineering tool, the use of the SysML language in the construction industry is discussed. The comparison between the various data flows suggests further researches both in the application of Systems Engineering in the construction industry and in the development of requirements management tools for managing a BIM-based construction process. Finally, recommendations for the effective implementation of innovative processes and technologies are proposed.

Lean enterprise web-based information system for construction (LEWIS): a framework

Abstract: Generating a realistic plan at the beginning of a project and maintaining its reliability throughout the construction is not an easy task. A case study of a 120 million pounds Private Finance Initiative (PFI) project in UK indicates unreliability of the construction plan (Percent Plan Completion (PPC) less 40%) which was caused by the lack of co-ordination among work-face personnel, project planners, and supportive organisations (i.e. designers, suppliers, and subcontractors). In this case, wastes regarding waiting for design information and discrepancy supply of resources are considerable. These wastes, apparently, lower productivity and affect time and cost of the project. Aiming to treat the above problems, this paper identifies an improvement strategy through a synergy of: 1) an innovative construction project management paradigm namely lean construction; and 2) the advanced information technologies namely web-based information management, and 4D visualisation. This has resulted in a developing prototype called "LEWIS - Lean Enterprise Web-based Information System for Construction". A unique structure of the system is an integration of product model, process model, and information management functions. Not being merely the information warehouse, the system allows planners to perform lookahead analysis, rehearse the plan, and visualise execution constraints in the 4D environment. It is envisaged that this system will facilitate co-ordination among project participants, increase reliability of construction plan, and improve on-site productivity. The focus of this paper is on the overall system architecture, information repository, and web-based interfaces while the 4D constraint-based analysis and visualisation is detailed in a companion paper.

Building Information Modelling as a Cost Control Tool for Critical Chain Construction Project Management

Abstract: The Critical Path Method (CPM) has been used in the construction industry as a project planning and control tool for a long time, however, project delays and cost overruns still happen. Compared to CPM, Critical Chain Project Management (CCPM) represents an improved management approach that focuses mostly on human behaviour and resource conflicts, addressing concepts like Student Syndrome, ParkinsonŐs Law and multitasking resolution. Additionally, CCPM simplifies project control and utilises buffers to reduce the risk of delay, bringing the project ahead of schedule without increasing costs. On the other hand, Building Information Modelling (BIM), being a methodology that enables enhanced and flexible management of construction project data within a virtual environment, could be exploited as a platform for the introduction of innovative project control methodologies into the construction management practices. This research aims to take advantage of BIM to support the implementation of Critical Chain Project Management methodology along the construction phase of a project. A framework for using BIM as a cost control tool to improve project buffer management is developed and analysed to facilitate the timely project execution and profit increase goals of the contractor.

SL/AM-IT: a CD-rom-based, interactive bibliography on service life and durability

Abstract: This paper describes a technology transfer technique to handle large corpora of technical information. The paper describes and illustrates a sophisticated Information Technology tool to interactively browse over 1500 abstracts and full text documents in the domain of service life and asset management. The first goal of the project is to provide full access to this compendium of information in the topic domain. The second goal of the project is to illustrate a methodology for data storage, data retrieval and technology transfer for other technology domains. The product described in this paper is a compact disk-read only memory (CD-ROM)-based, interactive bibliography on service life prediction, durability and asset management. There are two innovative features of this compendium: (1) a keyphrase index, that was created automatically using sophisticated indexing tools, and (2) an intuitive, interactive interface to large volumes of technical information. The paper describes the problems of accessing the existing large volumes of data and information related to service life prediction, durability and asset management, outlines sophisticated IT tools currently available for indexing and searching large corpora of technical information, details the interface and background data structure of the SL/AM-IT (Service Life/Asset Management-Information Technology) methodology and product, and discusses advantages of such techniques in the domain of service life and asset management and other similar technical domains.

Information technology foresight:the future application of theworld wide web in construction

Abstract: Information technology (IT) is fundamentally changing global construction business. TheInternet, and more specifically the World Wide Web (WWW) will be key to this change.Forecasting technological change is notoriously difficult. This is becoming furtherexacerbated by the increasingly evident cycles of over-hype and disillusionment that newtechnologies and management paradigms face.Science policy research has developed innovative forecasting methods to deal with such aproblem. Key within these is the use of scenarios to describe the integrative effects ofdevelopments in parallel technologies and their socio-economic context.This paper contains a detailed scenario of the way the WWW may be used in globalconstruction in the year 2001. Analysis of the scenario causes key questions to be askedregarding the impact of technology development in construction. These questions are inneed of urgent, serious consideration by: governments, senior construction executives,educators, students, researchers, recruiters, and new entrants to the industry.The answers to these questions will help shape a key component of the research andinnovation agenda for construction for what is left of this millennium.

A knowledge management framework for project definition

Abstract: This paper proposes a knowledge management framework for project definition of capital facility projects. The conceptual framework emphasizes project-based learning and the creation of group knowledge in early phase project planning and design activity. The use of multi-disciplinary expertise in this phase of project development acknowledges the use of multiple decision frames by which stakeholders approach project solutions. This research views project definition as a collaborative decision-making process, and highlights the need for supporting group management techniques and technologies. Project definition is regarded as the phase of project development where exploration of alternatives creates innovative problem and solution definitions that allows maximum customer value generation to be developed. This paper proposes a management framework to support organizational and process interfaces within project definition. The model is based primarily on findings from recent research literature and on exploratory descriptive research. The model presents a process for project definition and supports group knowledge creation and management. The model bases its development on soft systems methodology to support group cognition, learning and creative solution generation. Collaborative group theory is incorporated into the model to support project definition. The framework builds on theoretical principles of lean design and construction

Keywords: client purpose, group knowledge creation, decision-making, learning, organizational cognition, project definition.

Serious Games vs. Traditional Tools in Construction Safety Training: A Review

Abstract: For workers, the exposure to on-site hazards can result in fatalities and serious injuries. To improve safety outcomes, different approaches, namely traditional tools (TT), and innovative tools such as serious games (SG), have been implemented into the construction industry. However, evidence suggesting which one is more effective is not apparent. To bridge this gap, a systematic review was conducted to evaluate the literature on TT and SG in this study, and the strengths and weaknesses between them were discussed. The literature findings suggest that the conclusion regarding which one may be more effective is yet inconclusive due to the limitations of existing studies. However, it is noted that the overall performance of SG seems to be superior in several technical aspects mentioned in this paper compared to TT. Based on the findings of this research, we could see the implication that SG may have the potential to become an effective approach for delivering safety training in the construction industry.
