title An Evaluative Approach to Architectural Visualization

summary In the forthcoming globalization and virtual almost everything, we are indeed reliving a moment of history when, at the turn of the century, machines replace craftsman in mass-producing goods quicker, cheaper, ‘better’ and faster for the mass market regardless of the appropriateness in using the machine. So much so that the recent proliferation of computer graphics has reached a stage where many are questioning their validity and usefulness in the advancement of architectural discourse. This paper argues that the pedagogy of the use of the new tools should be effective communication in vision and in representation. In short, saying what you do and doing what you say, no more and no less, or to be ‘true’ and ‘honest’. The paper tries to provide a hypothetical framework whereby the rationale of drawing could be more systematically understood and criticised, and it reports ways the framework is introduced in the teaching of design studio. The focus of the experimental studio (Active Studio 1.6 beta) is to enable the substantiation of ideas and feelings through a critical manipulation of medium and techniques. The results are narratives whereby the expression of intention as well as the drawings are both on trial.

title Un Nuevo Horizonte Arquitectonico, Productivo e Intelectual (A New Architectural, Productive and Intelectual Horizon)
source II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 76-83
summary This work presents the pedagogical experience of a Design Workshop that investigated the impact of the digital and analogic means on the architectonic design process This work was based on the research of Dr. Arch. Julio BermÝdez who also directed this workshop in 1997. This class was part of the Training Program organized by the "Centro de Informatica y Diseho" (CID) at the "Universidad Nacional del Litoral" FADU (Facultad de Arquitectura Diseho y Urbanismo) Santa Fe, Argentina and made possible by the ongoing International Program of Academic Exchange between the FADU and the (University of Utah Graduate School of Architecture (IPAE Project NO 4). The experimental studio utilized an architectural problem to study the procedural, technical, interpretative and theoretical issues associated with the relationship of contemporary media and design process. The pedagogical vehicle was a program that expresses in itself the meeting or collision between two cultures competing for dominance at the end of the millennium: the immemorial material culture (corporeal, tectonic) and the new and everyday more influent virtual culture (information, nets, media, simulation). The premise for the design process, communication and criticism was the constant migration between the digital and analog representation systems. Within this theoretical-practical context semantic aspects containing different representation modalities were used such as physical and electronic models along with systematic and sensitive drawings (manuals, pixels and with CAD). Hybrid interfaces took a leading role in the process since they allowed the communication between analog and digital media through the creative and technical interaction between scanner, video and computer. This architectural and media context generated an intense pedagogic environment fostering the development of creativity and a critical attitude while allowing concrete breakthroughs in the teaching process and format design. Our work reflects on these results showing examples of stud-go works and providing a final evaluation of this unique experience in Argentina.

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title Virtual Studio of Design and Technology on Internet (I) - Educator's approach
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary This paper presents a teaching experience involving students and professors from various universities, in Italy and abroad, which began in 1996 and is still on going. The Virtual Studios on the Internet (VSI) have some features in common with the Teaching Studios planned for the new programme of the faculties of Architecture in Italian universities. These are the definition of a common design theme, and the participation of disciplinary teachers. The greatest difference is in the modes of collaboration, which is achieved through information and communication technologies. The chief result of this is that the various work groups in different places can work and collaborate at the same time: the computer networks provide the means to express, communicate and share the design project.

title Teaching CAD with Language Learning Methods
source Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 173-188
summary By looking at computer aided design as design communication we can use pedagogical methods from the well-developed discipline of language learning. Language learning breaks down a complex field into attainable steps, showing how learning strategies and attitudes can enhance mastery. Balancing the linguistic emphases of organizational analysis, communicative intent and contextual application can address different learning styles. Guiding students in learning approaches from language study will equip them to deal with constantly changing technology.

From overall curriculum planning to specific exercises, language study provides a model for building a learner-centered education. Educating students about the learning process, such as the variety of metacognitive, cognitive and social/affective strategies can improve learning. At an introductory level, providing a conceptual framework and enhancing resource-finding, brainstorming and coping abilities can lead to threshold competence. Using kit-of-parts problems helps students to focus on technique and content in successive steps, with mimetic and generative work appealing to different learning styles.

Practicing learning strategies on realistic projects hones the ability to connect concepts to actual situations, drawing on resource-usage, task management, and problem management skills. Including collaborative aspects in these projects provides the motivation of a real audience and while linking academic study to practical concerns. Examples from architectural education illustrate how the approach can be implemented.

summary Description of class research from 1997-2 to 2000-1 in “Applied Computing in Architecture” conducted in the sixth semester of the Architecture Program at Faculdade de Belas Artes de São Paulo. The study is intended to analyze, evaluate and discover new paradigms in the introduction/application of class methodologies of teaching the use of computer in the design process. Our intention is to verify the students natural understanding of the principles of 3D digital modeling by introducing new tools for defining space and form, using the computer as a communication/representation system, and not only as a mimetized production tool. The challenge was to find a natural syntony between the digital projectual process and the learning process. At the end of each semester we evaluated the results and redirected the class proposals.

title AIA CAD layer guidelines
source Washington, DC: The American Institute of Architects Press
summary The power and potential of computer-aided design (CAD) is based on the ability to reuse and share information. This is particularly true in building design and construction, a field that involves extensive information and teamwork between a variety of consultants. CAD provides both a common medium of exchange and a tool for producing the documentation required for construction and management. The key to realizing the potential of CAD is using common organizing principles. In particular, standard organization of files and layers is essential for efficient work and communication. Virtually all CAD systems support the concept of layers. This function allows graphic information to be grouped for display or plotting purposes. Intelligent use of layers can reduce drawing time and improve drawing coordination. By turning selected layers on or off, a variety of different plotted sheets can be produced. The layer is the basic CAD tool for managing visual information. By making it possible to reuse information, layers reduce drawing time and improve coordination. Layers and the new class libraries and object data complement, rather than compete with each other. Using layers to manage the visual aspects of graphic entities, with class libraries and object data to store the non-graphic data, gives architects an efficient way to work in CAD.

title BACnetTM: a standard communication infrastructure for intelligent buildings
source Automation in Construction 6 (5-6) (1997) pp. 529-540
summary Intelligent buildings require integration of a variety of computer-based building automation and control system products that are usually made by different manufacturers. The exchange of information among these devices is critical to the successful operation of the building systems. Proprietary approaches to providing this communication have created great challenges for system integrators and hampered the development of intelligent building technology. Even though digital automation and control technology has been widely available for more than a decade and islands of automation are common, intelligent buildings with integrated building services are still more of a promise than a reality. BACnetTM is a standard communication protocol for building automation and control networks developed by the American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE, Standard 135-1995: BACnetTM--A Data Communication Protocol for Building Automation and Control Networks. American Society of Heating, Refrigerating, and Air-conditioning Engineers. Atlanta, Georgia, USA, 1995). BACnetTM provides the communication infrastructure needed to integrate products made by different vendors and to integrate building services that are now independent. This paper describes the main features of the BACnetTM protocol and early experience implementing it.

source Maher, M. L., Gero, J. S. and Sudweeks, F. (eds), Preprints Formal Aspects of Collaborative Computer-Aided Design, Key Centre of Design Computing, University of Sydney, Sydney, pp. 387-403
summary In a multidisciplinary design environment, such as the AEC domain, the various designers will have their own concepts and representations of the design object making communication in such an environment a complex task. This paper argues for a multiple view approach based upon an assumption that different concepts of an object are based on different functional contexts. Thus an understanding of concepts such as function, purpose and intent is critical since the representation of the functional properties of design objects is the underlying basis for the formation of different concepts and coordination of these concepts. The paper points to the modelling of multidisciplinary design teams as cooperative intelligent agents in a distributed decisionmaking system where the explicit representation of function and purpose are essential, in a CAD environment, for the necessary communication of intent and effects.

title A National Strategy for CAAD and IT-Implementation in the Construction Industry the Construction Industry
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary The objective of this paper is to present a strategy for implementation of CAD and IT in the construction and building management#1 industry in Sweden. The interest is in how to make the best use of the limited resources in a small country or region, cooperating internationally and at the same time avoiding to be totally dominated by the great international actors in the market of information technology.

In Sweden representatives from the construction and building management industry have put forward a research and development program called: "IT-Bygg#2 2002 - Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry.

The presented strategy is based on a seminar with some of the most experienced researchers, developers and practitioners of CAD in Sweden. The activities were recorded and annotated, analyzed and put together afterwards.

The proposal in brief is that object oriented distributed CAD is to be used in the long perspective. It will need to be based on international standards such as STEP and it will take at least another 5 years to get established.

Meanwhile something temporary has to be used. Pragmatically a "de facto standard" on formats has to be accepted and implemented. To support new users of IT all software in use in the country will be analyzed, described and published for a national platform for IT-communication within the construction industry.

Finally the question is discussed "How can architect schools then contribute to IT being implemented within the housing sector at a regional or national level?" Some ideas are presented: Creating the good example, better support for the customer, sharing the holistic concept of the project with all actors, taking part in an integrated education process and international collaboration like AVOCAAD and ECAADE.

summary This paper briefly describes the implementation of an Internet-intranet information system applied to a large-scale project. The large-scale project is centered on the urban area around the Porta Susa railway station in Turin, Italy. The information system integrates the communicative tools used to facilitate and improve the collaboration between the different actors working on the project and the distributed environment used to elaborate the information across a wide area network. The main factors considered are those which exploit the potentialities of computers and networks for interaction and communication. One result is the possibility of interacting dynamically with the information, re-elaborating and distributing it in progress. The information systems opens different ways of collaboration between the project employees, and extends the participation in the project to the citizens.

source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 80-85
summary The architectural design business is marked by a progressive increase in operators all cooperating towards the realization of building structures and complex infrastructures (Jenckes, 1997). This type of design implies the simultaneous activity of specialists in different fields, often working a considerable distance apart, on increasingly distributed design studies. Collaborative Architectural Design comprises a vast field of studies that embraces also these sectors and problems. To mention but a few: communication among operators in the building and design sector; design process system logic architecture; conceptual structure of the building organism; building component representation; conflict identification and management; sharing of knowledge; and also, user interface; global evaluation of solutions adopted; IT definition of objects; inter-object communication (in the IT sense). The point of view of the research is that of the designers of the architectural artefact (Simon, 1996); its focus consists of the relations among the various design operators and among the latter and the information exchanged: the Building Objects. Its primary research goal is thus the conceptual structure of the building organism for the purpose of managing conflicts and developing possible methods of resolving them.

summary Collaborative design requires participation of individuals and coordination of design information and tasks. This paper focuses on the representations and communication channels in collaboration design. On the basis of a design communication model and findings of four collaborative design case studies, the phenomena of design communication are presented. The study also examines when the conditions of collaboration are achieved and what kinds of interfaces in computer-mediated collaborative work are needed, and propose a theme-oriented interface for computer-mediated collaborative design.

title Towards a Taxonomy of Virtual Reality User Interfaces
source Proceedings of the International Conference on Information Visualisation (IV97), pp. 17-29
summary Virtual reality based user interfaces (VRUIs) are expected to bring about a revolution in computing. VR can potentially communicate large amounts of data in an easily understandable format. VR looks very promising, but it is still a very new interface technology for which very little application oriented knowledge is available. As a basis for such a future VRUI design theory, a taxonomy of VRUIs is required. A general model of human computer communication is formulated. This model constitutes a frame for the integration of partial taxonomies of human computer interaction that are found in the literature. The whole model constitutes a general user interface taxonomy. The field of VRUIs is described and delimited with respect to this taxonomy.

title Management and Integration of Product Information in Construction: Reality and Future Trends
source The Int. Journal of Construction IT 5(2), pp. 19-46
summary For many years numerous efforts have been spent on the development of standardized approaches for modelling industrial information. During this period stand-alone software tools have been developed in most industries including the Building and Construction sector : Computer Aided Design (CAD) tools, technical software such as software development for energy analysis, project management systems, product databases etc. As this set of computer tools became more and more heterogeneous, the need for communication tools has emerged to enable data to be exchanged between them. Standardising data exchange then becomes a logical step in the improvement of the information management during the whole construction process. The aim of this paper is to put forward the state-of-the art in the domain of product model approaches and standards developments : ISO 10303 STEP, ISO 13584 P-LIB and ISO 15531 MANDATE. We will give a global overview of the existing applications in the construction sector, both in terms of product, or process models, most of them provided by either national or European projects.

title Inhabiting the virtual city : the design of social environments for electronic communities
source Massachusetts Institute of Technology, Program in Media Arts & Sciences
summary The goal of this work is to develop an approach to the design of on-line social environments. My thesis is that, in order to foster the development of vibrant and viable online communities, the environment - i.e. the technical infrastructure and user interface - must provide the means to communicate social cues and information: the participants must be able to perceive the social patterns of activity and affiliation and the community must be able to evolve a fluid and subtle cultural vocabulary. The theoretical foundation for the research is drawn from traditional studies of society and culture and from observations of contemporary on-line systems. Starting with an analysis of the fundamental differences between real and virtual societies - most notably, the presence and absence of the body - the first section examines the ways social cues are communicated in the real world, discusses the limits imposed on on-line communities due to their mediated and bodiless nature, and explores directions that virtual societies can take that are impossible for physical ones. These ideas form the basis for the main part of the thesis, a design platform for creating sociable virtual environments. The focus of the discussion is on the analysis of a set of implemented design experiments that explore three areas of the platform: the visual representations of social phenomena, the role of information spaces as contexts for communication, and the presentation of self in the virtual world.

title Wireless communication and computing at the construction jobsite
source Automation in Construction 7 (4) (1998) pp. 327-347
summary For many years, the walkie-talkie has been synonymous with the construction industry. During jobsite project execution, there are three variables which can either hinder or facilitate successful results, namely, quality, quantity, and timing of information. Wireless data communications technology is capable of delivering just-in-time information within the `last mile' between the trailer and a desired location on the jobsite. This paper reports on a study which surveyed information needs at the jobsite, emerging wireless data communications technology, and assessed the extent to which wireless data technology can fulfill the information needs of the jobsite [J.M. de la Garza, I. Howitt, Wireless communication and computing at the jobsite, Research Report 136-11, Construction Industry Institute, Austin, TX, 1997]. We have organized jobsite information needs into the following ten categories: (a) requests for information, (b) materials management, (c) equipment management, (d) cost management, (e) schedule and means and methods, (f) jobsite record keeping, (g) submittals, (h) safety, (i) QC/QA, and (k) future trends. Each category was analyzed in terms of its appropriateness to take advantage of wireless technology. The four formats considered to transmit information wirelessly were: (a) live voice, (b) live video, (c) batched data, and (d) live data. Current wireless communication technology has been classified into the following five classes: (a) circuit-switched wireless data systems, (b) packet-switched wireless data systems––this class was further subdivided into specialized mobile radio systems and cellular digital packet data systems, (c) wireless local area networks, (d) paging systems, and (e) satellite-based data communications. A primer for wireless communications covering both fundamental and advanced communications concepts has also been included to enable a better understanding of the issues involved in making trade-offs while configuring a wireless jobsite communication system. The example presented in this paper shows how a contractor can define a subset of information needs by choosing from those already articulated herein and determine if a given wireless technology should even be considered as a viable way of meeting the information needs that such company has.

summary This paper belongs to a suite of three interrelated papers. The two others are 'The VEGA Platform' and 'A Dynamic Product Model'. These two companion papers are also based on the VEGA project. The ESPRIT project VEGA (Virtual Enterprises using Groupware tools and distributed Architectures) has the objective to develop IT solutions enabling virtual enterprises, especially in the domain of architectural design and building engineering. VEGA shall give answers to many questions of what is needed for enabling such virtual enterprise from the IT side. The questions range from technologies for networks, communication between distributed applications, control, management of information flow to implementation and model architectures to allow distribution of information in the virtual enterprises. This paper is focused on the product model aspect of VEGA. So far modeling experts have followed a more or less centralized architecture (central or central with 4 satellites'). Is this also the architecture for the envisaged goal? What is the architecture for such a distributed model following the paradigm of modeling the , natural human' way of doing business? What is the architecture enabling most effective the filtering and translation in the communication process. Today there is some experience with 'bulk data' of the document exchange type. What is with incremental information (not data) exchange? Incremental on demand only the really needed information not a whole document. The paper is structured into three parts. First there is description of the modeling history or background. the second a vision of interoperability in an distributed environment from the users coming from architectural design and building engineering view point. Third is a description of work undertaken by the authors in previous project forming the direct basis for the VEGA model. Finally a short description of the VEGA project, especially the VEGA model architecture.
