summary Location is often considered as the most important factor leading to the success of public or private services. Location is the key in maximising accessibility and keeping operating cost low. A collaborative research project between ‘Nottingham University’ and the ‘Environmental ServicesDepartment of Nottingham City Council’ is developing an ‘Intelligent Map’ for identifying optimum locations for the recycling centres in the city. The object is to develop a new decision support system for urban planners, to be used as a management and analytical tool for improving locational decisionmaking. This paper discusses the technique of the Intelligent Map, and its concept. The paper includes three main sections. The first discusses the introduction of the mini-recycling centres in Nottingham, theproblems associated with their spatial distribution, and the need for a new decision support system using GIS technology. The second examines traditional techniques using GIS for identifying optimum locations and calculating catchment areas. The third explains the concept of the Intelligent Map; discussion takes the form of an initial analysis of the likely method to be applied, and then briefly outlines some of the prototyping work that is currently taking place at Nottingham.

title A comparison of land valuation methods supported by GIS
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary The purpose of this work was to study three different strategies for the appraisal of urban land. The first, a theoretical strategy created by the authors of this study to reproduce the common conditions of Brazilian cities, uses increments and reductions in the value of a square meter of land according to each lot’s individual features. The second method, based on Multiple Regression techniques, is widely used for valuation purposes. Finally, the effectiveness of Artificial Neural Networks to deal with thiskind of problem is studied. A sample of 157 lots was collected from several neighbourhoods of a small Brazilian city for the case study. The lot features recorded were area, width, shape, distance to the downtown district of the city through the street network, existence of fences and paved sidewalks, and market price. Prediction errors have been estimated for each of the three methods in order to compare their results. Predicted and error values, added to Geographical Information Systems, may be used to build thematic maps and to check how each strategy applies to different areas of the city. The analyses of error values conducted in this study showed that Artificial Neural Networks presented the best performance as a land appraisal method for the case studied.

summary Generative design formalisms utilise discrete, constructive steps to encode strategies for formal change. In physical design media, the pervasive metaphor for doing design is the direct and continuous manipulation of the developing form. The goal of our investigation is to develop mixed initiative approaches to design exploration. In this paper, we address how constrained manipulation in generative systems can support both discrete and continuous modes of interaction. Massing is a common strategy for processing conceptual notions about three dimensional form. We use massing models of tenth century temple cellas as an example to illustrate an environment for constrained manipulation.

title The Role of Artifacts in Collaborative Design
source CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 271-280
doi https://doi.org/10.52842/conf.caadria.1998.271
summary With the proliferation of digital technology, a new category of design artifacts, usually described with the term virtual, has emerged. Virtual artifacts have gained further prominence due to the advances made in collaboration software and networking technologies. These technologies have made it easier to communicate design intentions through the transfer and sharing of virtual rather than physical artifacts. This becomes particularly true in the case of long-distance or international collaborative efforts. This paper compares the two major categories of artifacts – the physical and the computer-based – and places them in relationship to an observed collaborative design process. In order to get at their specific roles in collaboration, two case studies were conducted in which designers in academic and professional settings were observed using a methodology which focused on participation in the everydayness of the designer as well as casual discussions, collection of artifacts, note-taking, and detailed descriptions of insightful events. The collected artifacts were then categorized according to the setting in which they were created and the setting in which they were intended to be used. These two attributes could have one of two values, private or public, which yield a matrix of four possible categories. It was observed that artifacts belonging in the same quadrant shared common qualities such as parsimony, completeness, and ambiguity. This paper finds that distinguishing between physical and virtual artifacts according to their material and imagined attributes is neither accurate nor useful. This research illustrates how virtual artifacts can obtain the qualities of their physical counterparts and vice versa. It also demonstrates how a new meta-artifact can emerge from the inclusion and unification of its material and imagined components. In conclusion, the paper calls for a seamless continuity in the representation and management of physical and virtual artifacts as a prerequisite to the success of: (1) computer-supported collaborative design processes, (2) academic instruction dealing with making and artifact building, and (3) executive policies in architectural practice addressing the management of architectural documents.

summary New technologies like Computer Aided Design and network facilities are affecting the building procurement, design and construction processes very rapidly, in the education, design studio teaching as well as in the practice. Network technologies are giving us a variety of possibilities: quick and simple access to information, quick and easy communication, exchange of data in different formats (texts, data, drawings, images, animations, hypertext or multimedia products, etc.) or access to differently located computer and work on it. As the result the communication or collaboration in a design and construction process and management could be used not only in the CAD based design studio but, what is more important, between geographically dispersed members of design teams (dispersed in different places, towns, regions, countries or even continents). There is a lot of advantages: quick and easy communication and exchange of information, free choice of a team, easy revisions of a documentation, collaborative work on the same drawings, costs savings in travelling, issuing, copying and shipping, etc. On the other hand the long-distance education on an international base appears like a modern teaching tool. Paper reflects the experiences from International collaborative studio work via computer network, Internet and World Wide Web.

title Animate Form
source Princeton Architectural Press, New York
summary Animate Form is a book and interactive CD-ROM of recent architectural projects designed by Form, the office of Greg Lynn. The projects documented here explore the potential of time-based animation techniques to inform architectural design. Historically, architecture has been considered static, fixed, and inert. Through the use of state-of-the-art animation and special-effects software, Lynn transforms space and form into highly plastic, flexible, and mutable entities. He uses topological geometries to bend, twist, deform, and differentiate structure, creating unprecedented departures from preconceived notions of architecture. In experimenting with these new methods and media, Lynn has charted an innovative direction in design. The book provides a theoretical context for the experimental projects through a collection of texts by Lynn, extensively illustrated in color. The CD-ROM is an interactive hypertext environment that fully documents the design processes used to generate the projects through animations, renderings, model photographs, videos, and texts. Using a virtual 3D interface, the viewer is able to navigate through space and select objects and animations to view at different scales.

title Decision Support for Improving Public Transport Network
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary When dealing with accessibility in a public transport network, isochronous maps are the common rule. Those maps are based on shortest distance algorithms run over simple or simplified networks. This contribution aims at representing the actual spatial distribution of the public transport offer in order to improve the usefulness to the urban community and to predict the evolution of the network according to the expected development of the agglomeration. The study combines the street (walking distance)and public transportation (buses) networks. The analyses rely on timetables and road maps completed by the public transportation company (TEC). Moreover, it makes use of built-up areas derived from satellite imagery. The processing requires raster- as well as vector-based procedures which have been achieved notably with the IDRISI software. Nevertheless the implementation of the decision rule relies on an original routine written by the authors. The area of interest concerns a part of the agglomeration of Liège (Belgium), including two secondary poles, highlighting their relation with the centre of the city and with each other. First the paper presents the typology of the public transport routes. Then the methodology elaborated for each transportation type is analysed; the shortestdistance routes and their alternatives are extracted and combined within a raster process. The obtained results and their operationality are finally presented and the paper concludes with possible improvements of the methodology.

source II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 398-405
summary Motivated by a tendency towards the development of international design and construction consortia, the paper explores the application of information technology in order to add an international and multicultural dimension to our Design Studios. In particular, the paper describes how a group of 4 Mexican design professors offers distance education to a Design Studio in the U.S. and how, in a reciprocal way, 4 American construction professors offer distance education to a Construction Studio in Mexico. Both groups of professors and students make extensive use of the Internet and a T1 dedicated line for compressed video. In addition to the experience previously mentioned, the paper elaborates on potential applications of the "Reciprocal Distance Education" model at university and professional levels. The paper presents conclusions that place particular attention in the evaluation of information resources. In the same way, some conclusions address the administrative an faculty structures that make possible the implementation of the model.

source Computers in Design Studio Teaching [EAAE/eCAADe International Workshop Proceedings / ISBN 09523687-7-3] Leuven (Belgium) 13-14 November 1998, pp. 157-164
doi https://doi.org/10.52842/conf.ecaade.1998.157
summary Although the use of computers has become widespread among architecture students, their use in design studios often lacks integration. To gain maximum advantage from computers, design students must acquire a breadth and depth of knowledge that allows them to choose the right tools, integrate multiple technologies, and apply knowledge to new situations. It is not possible for students to gain all of this knowledge in an ad hoc way as part of a design studio. Thus, an introductory CAAD course is a necessary prerequisite for participation in design studios that employ computer methods. The paper presents the experience of two faculty members currently working on the integration of their second year introductory CAAD courses and their fourth year Electronic Design Studios. The paper describes the pedagogical methods used in the introductory CAAD courses, and shows how they serve as the foundation for exercises in upper level electronic design studios. The paper also presents plans for the implementation of distance education methodologies in the delivery of computing and studio courses. The paper ends by providing conclusions that address how the use of computer technology permits the addition of instructional objectives that go beyond those of conventional design studios.

summary Continually being redeveloped since its inception six years ago, Virtual Design Studio (VDS) represents a new method of practicing and teaching design. This paper focuses on a recent project which used VDS in a professional context: a design competition entry for the 2006 Winter Olympic Games. Separated by six time zones, the authors offer distinctive views of VDS, discussing the creative aspects of long-distance design collaboration using both synchronous and asynchronous modes of communication. The authors consider Information Technology (IT) as a facilitator for design collaboration, and examine in this paper the extent to which this new condition expands the possibilities of creative design work.

summary Over the past few years, we have seen that the evolution of the Internet and World Wide Web technologies have significantly enhanced the global communication and collaboration. People, no matter where they are, are virtually getting closer and closer. The barriers that came from time and distance have been partially removed by the use of such technologies. Internet and WWW are not just technology, they are an environment or space. With such breakthrough in technologies, a new paradigm in education is there. The education very differently from what we have now. This paper presents an Internet-based environment to support teaching and learning in architecture education. We will discuss the design concept and how to integrate the technology and knowledge-based techniques to implement the learning environment for architecture students. Architecture is a very specific discipline which consists of the knowledge from arts, sciences, engineering, and more. One of the focuses in architecture education is to teach how to express and communicate design ideas with the multimedia or other technologies, such as, virtual reality (VR). A case study presented in this paper is about how to deliver and present the ancient Chinese temples and its bracket set systems from the server to the browsers to support distance teaching. That is, students and teachers may not be in the same location, but they are able to watch the same objects and to exchange ideas. We will discuss how to use multimedia technologies to illustrate how a temple and its bracket set differ from dynasties to dynasties and introduce its basic properties to the viewers. Moreover, we will discuss how we organize and handle 3-dimensional objects with such system. Many people are still arguing about whether Internet-based teaching or a real classroom setting is better. We are not implying that Internet-based teaching is superior or predicting that it will dominate the teaching in the near future. However, we strongly believe that it is just another alternative to express and represent architectural thinking to over some of the barriers that come from time and distance. We believe, that it is always true, that the Internet-based teaching may provide both teachers and learners greater flexibility and to support more International collaboration. That is, regardless where the students or teachers are, they can always participate in learning or teaching and make teaching and learning much more rich and interesting.

summary A computer program is being elaborated as an aid in designing assembled parts whose assembly presents high degrees of complexity. The newly created program, once incorporated in the CAD sector to increase its potential applications, will facilitate the analysis of reciprocal relationhips between pieces of the assemblage; this will enhance optimum decision-making in terms of geometric and functional characteristics with respect to the previously conceived assembly sequence. The program will automatically create images in three different ways: instantaneous images of assembly stages for each piece of the assembled part; exploded axonometric view of the whole structure with indications of necessary procedures for inserting or connecting the assembled part;sequenced procedures for connecting the assembled part. The different methods of visualization listed above will allow for project verification of the part by means of simultaneous visual analysis of the images and rapid updating should any changes in their properties arise. These types of visualization include simulations of piece by piece assemblage, which will facilitate an "optimal assemblage", meaning a set of components which are assembled in a specific sequence according to their "structural compatibility" and taking into consideration "particular assembly requirements".

doi https://doi.org/10.52842/conf.ecaade.1999.169
summary Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

title A Feature-Based Description Technique for Design Processes: A Case Study
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary In order to develop appropriate tools for decision support in design processes, it is necessary to found them on an understanding of design. Analytical techniques of design processes that have a direct relationship with tool development can enhance design support systems development. The paper focuses on a design support system in the VR-DIS research program. The aim of this research program is to develop insight in the architectural design process and to establish design tools for architectsworking in Virtual Reality. The basic approach for data modelling in VR in this research is based on an extension of the Feature Based Modelling paradigm taken from design in mechanical engineering. The computer model of the design in the system is a Feature-based model. This paper describes design processes in terms of changes in the Feature-based model of the design. For this purpose, a case of a house design is used. Drawings in the conceptual design phase up to the preliminary design phase arestudied. Each state of the drawings is described in terms of a Feature-model. Particular design actions such as creation of spaces, definition of architectural elements, and changes during the design process can be expressed in terms of changes in the Feature-model. Because of the use of Features, the changes can be formalised in the VR-DIS system. The description in terms of Features offers an analytical toolthat leads to a functional brief for design support tools. The paper ends with a discussion of implications and future work.

source Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 141-145
summary In a chain of "real - perceived - imagined space" the computer reduces to a uniform model of only real and imagined space. It cannot undertake man's function or it cannot build the perception model. However, perception assumes physiological perception, psychological estimation and understanding, and emotional ho-experience. For a person the seizing of space during perception is constructing temporary spatial images and their development. The communicative relations of the person with environment are established during revealing internal and external structural communications and the interior represents the message, unwrapped in space and perceived in time. The real space is formed under influence of the sum of conceptual restrictions. The character of these restrictions depends on a super idea, a type of an initial situation, character of installations and on social-cultural stereotypes of the author. Without this stage transition to real architectural object is impossible. Result of activity of an architect at this stage becomes creation hypothetical cyberspace, with its own peculiarities and laws.

title On the process of creativity in puzzles, inventions, and designs
source Automation in Construction 7 (2-3) (1998) pp. 123-138
summary The most common means of identifying creativity has been through its products. In architecture, music, writing, art, even puzzle solving and scientific discovery, the prerequisite for considering creativity has been the presence of a creative product. Alternatively, anecdotal descriptions have been used to identify processes that are considered creative. Many scientific discoveries have been linked to a sudden realization or unexplainable revelation punctuated with the AHA! response. Outside of the creative product itself and the AHA! response, the kinds of concrete evidence that point to the process of creativity are precious few. Our purpose here is to further examine these phenomena and develop hypotheses about the nature of the creative process. Our ultimate aim is to develop a general theory of creativity. We intend to base this theory on a set of conditions that are necessary for the creative process to take place in a number of domains: puzzles, scientific discoveries, and design, with special emphasis on architectural design.

title Computational Specification of Building Requirements in theEarly Stages of Design
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary We have been exploring computational techniques to help building designers to specify design requirements during the early stages of design. In the past, little has been accomplished in this area either in terms of innovative computational technologies or the improvement of design performance.The prospect of improving design productivity and creating a seamless process between requirements specification and formal design are our primary motivations. This research has been conducted as partof a larger project entitled SEED (Software Environment to Support Early Phases in Building Design). SEED features an open-ended modular architecture, where each module provides support for a design activity that takes place in early design stages. Each module is supported by a database to store and retrieve information, as well as a user interface to support the interaction with designers. The module described in this paper, SEED-Pro (the architectural programming module of SEED), is a workingprototype for building design requirements specification. It can be used by other modules in SEED or by design systems in other domains, such as mechanical engineering, civil engineering, industrial designand electrical engineering. Our approach to SEED-Pro is divided into two phases: core, and support functionalities. The core functionalities operate in an interactive mode relying on a case-based approach to retrieve and adapt complex specification records to the problem at hand. The supportfunctionalities include the case-base, the data-base, and the standards processing environment for building specification tasks. Our findings indicate that SEED-Pro: (1) is a tool that structures the unstructured domain of design requirements; (2) enables the integration of design requirements with the rest of the design process, (3) leads to the creation of complex case-bases and (4) enables the observation of their performance in the context of real world design problems.

title A Web-Based Virtual Reality Model for Preliminary Estimates of Hi-Rise Building Projects
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Cost estimating of a construction project at its early stage is considered to be very important task since it will be used as a base to commit or otherwise not to commit funds to that project. Preparation of a reliableand realistic preliminary estimate to aid the decision makers to commit funds for a specific project is a complicated assignment. Traditional methods and operations produced unsatisfactory aid due to lack ofaccuracy especially in the pre-design stage of a project. This participates in the increase of percentage of bankruptcy in the construction industry, which has dramatically climbed up and ranked as 15 percent of thewhole bankruptcies claimed in Canada (Statistic Canada 1998). This paper presents a methodology for developing and a Web-based model to automate preliminary cost estimates for hi-rise buildings. This is achieved by integrating a database with design drawings in a Virtual Reality (VR) environment. The model will automatically generate preliminary estimates after modifying a 3D CAD drawing. It provides the user the option to visualize and simulate the drawing and its cost data through VR environment. Having done that, it will allow owners, architects and cost engineers to view a constructed building project, change its geometric objects and shapes, and accordingly generate a new conceptual cost estimate.
