The learning of CAD for construction: technical abilities or visual?

Abstract: The increasing demands of the construction industry for individuals with good IT skills add continuous pressures on higher education to improve their methods of teaching. CAD training, as an important part of IT training for construction students, is becoming an essential part of the curriculum in most built environment schools. However, general CAD training is mostly concerned with providing students with technical skills rather than the initial ability of spatial visualisation. Indeed, existing training methods of CAD applications, do not take into consideration students? learning styles, and the differences in their spatial visualisation abilities. Considering that CAD students need to perform various activities within CAD applications to develop an understanding of building concepts and components, their spatial visualisation abilities and their learning style, remain the main barriers. This paper identifies the learning strategies required to assist with the learning of 3D modelling and describes a new approach adopted to examine students' Special Visualisation Skills. The paper also describes innovative e-learning approaches developed to reinforce students' learning of 3D CAD, tracking their progress and highlighting qualitative measures of their effectiveness.

Information link model for construction using artificial intelligence

Abstract: This paper reports on a novel project model developed to help clients plan, monitor and control their construction projects. It describes a knowledge-based system designed for this purpose. The paper initially concentrates on the practical aspect of knowledge acquisition indicating problems that were faced and solutions employed. Following this, the structure of the knowledge-based system which was developed is outlined and its use described. Conclusions are drawn as to the applicability of the model and the final system. The work undertaken shows that it is feasible to benefit from the field of artificial intelligence to develop a project manager assistant computer program that utilises the benefit of information and its links.

Architecture and HCI: a review of trends towards an integrative approach to designing responsive space

Abstract: Recently, trends in integrating dynamism and response in Computer Aided Architectural Design have been in vogue. Attempts to attach dynamic forces to vector objects and thereby breeding amorphous elements and responsive environments are demonstrated through numerous design proposals in recent times, where design concepts are represented as active systems of forces affecting CAD objects; turning them into responsive amorphous organisms. This intention is compromised once such active forms are translated into built objects from the simulations, which largely remain inert. On the other hand, recent concepts in Human Computer Interaction (HCI) and pervasive computing, have demonstrated relevance in physical objects and spaces; turning them into elements of physical interface to mediate particular human actions, aspects of communication, entertainment and aesthetic expression. While responsiveness grows as a concern amongst architects, allowing HCI features and computational schemes to become integral processes and parameters within architectural design may provide design processes with new approaches to architectural production. This may, in turn, alter the resultant architectural schemes and their behavior. This paper reviews relevant developments that contribute to such potential to inform physically responsive environments and scopes their integration in heterogeneous architectural design processes.

A framework for research of IT application in Croatian construction companies

Abstract: Croatian construction companies are passing dramatically changes by privatisation and restructuring according to the market needs of today and especially during future huge reconstruction and development of Croatian (as well Bosnia and Herzegovina) economy. The market conditions in these Republics are for now: scarcity of financial means, scarcity of personal educated and trained in modern management methods, scarcity of some profiles of skilled people in construction, very strong competition of foreign companies, since Croatian (and B and H) market is now open for foreign companies. The specific after war conditions include also new legal and business structure (completely new legislative based on the practice of developed western democratic states) new financial structure and institutions (also based on the financial structure of the developed countries). In the chaining of the subsystems: [ ownership - undertaking - management - transformed ownership] , information technology is fundamental but not sufficient enabler for quality decision making and efficiently management of the construction processes. Based on the IT application, there are necessary educated and trained management people, adequate decisions, and realisation. By adequate IT application design and construction processes are probably rationalised and accelerated, by satisfaction of the high quality standards, so that construction companies could easier adapt to market needs. What are necessary prerequisites (organization, IT, personnel, other) for making and carrying out of the quality decisions? In which degree IT application (modern information technologies, expert systems, CAD/CAM, GIS, CASE) influence on decision quality? What are other factors are influencing (knowledge degree, psychological state, environment, market)? On such question have been proposed and accepted research program under the name "Development of IT application in Croatian construction companies" by Croatian Ministry for science and technology. The goals: * Continually research of development of IT application in companies that are active in design, construction and maintenance of construction objects. * Comparative overview of IT application state to different criteria * Proposition of strategy development of IT application in construction * Creation of IT data base for information and experience exchange between the foreign and domestic construction companies * Proposition of education programme of IT application in construction * The questionnaire is now in distribution, and research will be carried out in the next three years. * The paper will explain the research approach, and eventually the first results.
