The Virtual Construction Simulator: Evaluating an Educational Simulation Application for Teaching Construction Management Concepts

Abstract: Understanding the dynamic nature of the construction process and the ability to make important decisions about resource utilization, sequencing, site layout, and project-related risks are critical skills for design and construction engineering students. Novice students lacking experience face challenges in learning and understanding how to manage risks, cost and time tradeoffs. An evolving area of research concerns the use of educational computer simulations to enhance the learning experience.The current development initiative at the Pennsylvania State University explores the value of educational simulations in teaching construction concepts such as scheduling, site congestion, resource management and resource allocation. The Virtual Construction Simulator (VCS), an interactive simulation game currently being developed and implemented, aims to engage students in an experiential simulation environment where they develop a construction schedule and make initial decisions about construction methods, resources, and activity sequence; and subsequently enter the simulation mode where certain factors and events are triggered. Stepping though the process, students assume more active role in learning the difference between the as-planned and as-built schedule resulting from the impact of factors such as weather, congestion, learning curve, or overtime based on construction project conditions.This paper discusses the development, and the results following the first implementation of the VCS simulation game this spring within the third year introductory course to Building and Construction Management course at Penn State. The pedagogical value of the VCS simulation game in fostering engaged, motivated, and deeper learning complementing the traditional teaching methods is also discussed.

Information technologies for knowledge management: their usage and effectiveness

Abstract: Knowledge is increasingly being recognised as a vital organisational resource that provides competitive advantage. Managing knowledge assets can be a challenge, especially in the construction industry, where short-term working contracts and temporary coalitions of individuals can inhibit knowledge sharing. The role of information technology (IT) in knowledge management (KM), is an essential consideration for any company wishing to exploit emerging technologies to manage their knowledge assets. This paper presents research, which has been conducted to identify the technologies that are currently used to manage knowledge in the construction industry. The effectiveness of these technologies has also been explored, highlighting the strengths and weaknesses of particular IT for KM. In addition, it attempts to highlight some of the challenges and complexities associated with managing knowledge in a project-based environment. A postal questionnaire was distributed among construction organisations in order to obtain generalisable data about the role of IT for KM, in the construction industry. This approach was supplemented by ethnographic interviews to reveal richer data about the nature of IT for KM, in five small, medium and large construction organisations. The research revealed that conventional technologies, such as the telephone, are used more frequently to manage knowledge, than more radical IT, such as Groupware or video-conferencing. In construction organisations, the potential benefits of IT for KM, are not fully exploited and many have expressed a need for greater implementation of IT, appropriated by sufficient training and education of staff

Design as problem handling - outline of a framework

Abstract: This paper presents an ongoing work concerning the development of a theoretical framework for design. The framework is intended to be applied to the development of information systems for architectural design. The paper combines ontological and epistemological perspectives using Bunge’s work as a starting point, supplemented with Schön’s studies of the general nature of design, and with examples of architectural design from Janson’s empirical studies of the Swedish architect Jan Gezelius’ works, as well as the author’s own reflections and conclusions

An ergonomics model for product design

Abstract: This paper models the integration of ergonomics knowledge to the design process. It is suggested that, neither a single methodology, nor an information system will be sufficient to cover all the requirements of an ergonomic product. The relative emphasis given to ergonomics varies with the types of design problem. Nonetheless, it is assumed that the design process will always involve the user, thus ergonomics. The difficulties arise from ill-defined nature of design, inadequate knowledge background or inadequate data which requires a long-tern approach where everything should be thought at macro level. For this purpose, the aim of the paper is to propose a communication model for ergonomists and designers who believe in the value of experts. Therefore, this model presents a macro outlook onto ergonomics and product design, whereas further studies may extend the scope by presenting sub-models for reaching details in the design process or existing micro models (expert or aiding systems) will be valuable sources if they are inserted into this system. "he research is focused on literature search, accident analysis and design strategy analysis. The chief questions to be addressed in the literature search are: - What is the relation between design and ergonomics? - What is designer's responsibility in terms of design, manufacturing and products liability? - What kind of ergonomics information do designers need? How reliable are they? . - What is meant by product-user interaction? The chief questions to be addressed in accident analysis are: - What kind of information does accident analysis provide? - What is the reliability of accident data?. - How is this information used in design? The chief questions to be addressed in design strategy analysis are: - What is a model and what type of models exist in design? - What is design management? - What is a product life-cycle? reputation? . - What are the benefits of product safety in terms of company's reputation?

Integrated Data Analytics-Simulation Framework for Proactive Assessment of Safety Performance

Abstract: Although considerable advances in the proactive control of construction project risks have been reported, identification and assessment of safety-related measures on safety performance remains challenging. This has been attributed to (1) difficulties in data collection; in particular, establishing the number of safety-related measures required to assess their influence on safety performance and (2) difficulties addressing the dynamic nature of projects; in particular, how measures affect safety performance over time. This papers aims to address these issues by implementing a framework that integrates existing departmental data with simulation models to proactively assess and predict safety performance. The framework is composed of three main components. First, safety-related measures available in various departmental databases are identified; second, the relationship between safety performance and measures is analysed and indicators with significant influence are incorporated into the assessment model; and third, a simulation model that reproduces the behaviour of these measures is used to test various scenarios. As evidenced by the results of a case study, the framework proposed here can assist companies with the proactive development of risk-avoidance strategies, thereby improving safety performance.

A PROPOSAL FOR REUSING SIMULATION MODELS IN THE DESIGNOF PRODUCTION SYSTEMS IN CONSTRUCTION

Abstract: One of the main difficulties of using simulation in the management of construction projects is the fact that developing simulation models is time consuming. One of the possible strategies to cope with this problem is the reuse of an existing model or part of it in other simulation study. Although many authors have pointed out that the unique nature of construction projects leads to the necessity of starting each model from the scratch, the reuse of models for simulating projects of the same market sector seems to be reasonable. This paper aims to assess the main benefits and difficulties of developing reusable simulation models for designing production systems for housing projects. A case study in which a simulation model was developed for supporting that task in a construction company involved in repetitive housing projects is presented. The development of this model took into account the possibility of reusing it in other similar projects of the company in order to reduce the time for doing the simulation study. The main findings are related to the limitations and requirements of reusable models as well as to the implementation of those models in the design of production systems for real construction projects.

THE CHALLENGES OF SCHOOL EDUCATION IN AN INFORMATION SOCIETY

Abstract: The difficulty in understanding the future implications of new technologies in society is seen in the growth of the internet throughout the world, and in particular, in schools. As factors such as convergence, increased bandwidth, "edutainment", multitasking and changes to traditional socialization modify everyday life. There is a corresponding need to consider the ways in which emerging practises and beliefs challenge traditional assumptions about the nature of school education. Although schools are by nature conservative and can be resistant to reform, the collective influence of an increase in the number of networked computers, improved teacher training, and the impetus of a transformed culture in a wide society are likely to lead to a reconsideration of the nature of schooling

DESIGNING A WEB BASED E-LEARNING SYSTEM FOR THE FEDERAL UNIVERSITY OF TECHNOLOGY YOLA

Abstract: During the last decade, the Web has changed from a simple hyper textual repository of documents to a powerful communication media. This shift has made Web applications highly suitable for the support of educational activities, which often include collaborative sessions. Although educational institutions are by nature conservative and can be resistant to reform, the collective influence of an increase in the number of networked computers, improved teacher training, and the impetus of a transformed culture in wider society are likely to lead to a reconsideration of the nature of education. The traditional emphasis on print in educational system is likely to be challenged by a range of screen-based and telecommunications mediums. Thus, this thesis proposes the design of a web-enabled Learning Management System – FRANKSTWEBS - built with the latest generation web technologies for FUTY. Modular, scaleable, and easy to implement and learn, one can track and manage any type of learning asset from online training, assessment, testing and corporate web sessions to classroom-based training.

Information-management-systems used by the Hong Kong construction industry

Abstract: This paper presents the results of current research into the extent that construction IT is used to support the large and dynamic construction industry of Hong Kong. The 1990’s have seen a continued growth in construction with the Government’s airport-core-programme of projects taking centre stage against a backdrop of a growth in construction of infrastructure and other public-sector and private-sector building works. Through economic necessity, the Government of the Hong Kong Special Administrative Region (S.A.R.) plans to promote significantly more construction within the territory of the Hong Kong S.A.R., over the next two decades This is essential to meet the growth demands that are forecast to occur over the medium-term planning horizon of fifteen years. Concurrently, economic expansion in the neighbouring regions of southern China requires considerably greater amounts of new infrastructure. The Hong Kong construction industry will, inevitably, want to be heavily involved in these business opportunities. It is presumed that these demands for construction will attract participation from the global construction industry. The relative exploitation of construction IT for competitive advantage, by competing construction companies from different parts of the world, has therefore become important to the industry in Hong Kong. The Hong Kong construction industry has an enviable reputation and it is to be expected that this high-performance is supported by the use of construction IT technologies. However, Futcher and Rowlinson have previously presented subjective arguments that ‘Hong Kong’s reputation for high-speed, on-time and within-budget, construction belies the rudimentary nature of the industry’s exploitation of IT’, that ‘Hong Kong [is] strong in hardware, telecommunications and the marketing of technology. Opposed to weakness in systems support; programming; IT services, such as implementation and operational administration; documentation; and user-training’. They have stated that ‘the industry is likely to adopt IT only if it is seen as an accepted good practice. It does not actively seek IT solutions to achieve competitive advantage; as a means of offence and defence; to reduce costs; to innovate; or to impress.’ The research provides a factual basis for these statements by way of a comparative assessment on the use of construction information technologies in the Hong Kong industry. Knowledge which is of value to all the participants pursuing new business in this dynamic market. It is indicative of the sino-asian construction industry’s perceptions of the value and utility of construction IT. The paper provides argument for industry-lead development of construction IT.

A prototype distributed CIC system based on IAI standards

Abstract: A prototype Computer Integrated Construction system is being developed that models building product and process information using International Alliance for Interoperability standards. The goal of this research is to provide a window into the future of how these standards can be applied in the construction industry. The prototype consists of a project database that is structured according to a common project schema or project data model. The schema is based on emerging International Alliance for Interoperability standard models but it is implemented in a way that allows the dynamic development of the schema (and even of its underlying metamodel) without destroying the information in the database in order to support on-going work in the development of information model standards. The system is modular in nature so that it can be supplemented with plug-in tools to accomplish a variety of project management tasks. It is served over the web through a combination of Microsoft's Active-X Data Object technology and a lightweight version of ISO STEP's Standard Data Access Interface. Data sets served to the client are wrapped in the Extensible Markup Language to allow for the self-description of information.
