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	Information technology and building performance
source	Automation in Construction 8 (4) (1999) pp. 411-415
summary	The quality of the built environment depends critically on the concept of sustainability and, in particular, on designs which are energy efficient and environmentally friendly. This paper gives an account of the successful application of computer-based simulations of the physical environment made available to architects through an Energy Design Advice Scheme. It goes on to indicate how emerging multi-media technology can be used to provide an explanation, particularly to those who are technically unsophisticated, of the complexity of the way in which design decisions impact upon the energy efficiency and environmental friendliness of buildings.

title	Modelling architectural design information by features : an approach to dynamic product modelling for application in architectural design
source	Eindhoven University of Technology
summary	Architectural design, like many other human activities, benefits more and more from the ongoing development of information and communication technologies. The traditional paper documents for the representation and communication of design are now replaced by digital media. CAD systems have replaced the drawing board and knowledge systems are used to integrate expert knowledge in the design process. Product modelling is one of the most promising approaches in the developments of the last two decades, aiming in the architectural context at the representation and communication of the information related to a building in all its aspects and during its complete life-cycle. However, after studying both the characteristics of the product modelling approach and the characteristics of architectural design, it is concluded in this research project that product modelling does not suffice for support of architectural design. Architectural design is characterised mainly as a problem solving process, involving illdefined problems that require a very dynamic way of dealing with information that concerns both the problem and emerging solutions. Furthermore, architectural design is in many ways an evolutionary process. In short term this is because of the incremental approach to problem solving in design projects; and in long term because of the stylistic development of designers and the continuous developments in the building and construction industry in general. The requirements that are posed by architectural design are concentrated in the keywords extensibility and flexibility of the design informationmodels. Extensibility means that designers can extend conceptual models with definitions that best suit the design concepts they wish to utilise. Flexibility means that information in design models can be structured in a way that accurately represents the design rationale. This includes the modelling of incidental characteristics and relationships of the entities in the model that are not necessarily predefined in a conceptual model. In general, product modelling does not adequately support this dynamic nature of design. Therefore, this research project has studied the concepts developed in the technology of Feature-based modelling, which originates from the area of mechanical engineering. These concepts include the usage of Features as the primitives for defining and reasoning about a product. Features have an autonomous function in the information model, which, as a result, constitutes a flexible network of relationships between Features that are established during the design process. The definition of Features can be specified by designers to formalise new design concepts. This allows the design tools to be adapted to the specific needs of the individual designer, enlarging the library of available resources for design. In addition to these key-concepts in Feature-based modelling as it is developed in the mechanical engineering context, the project has determined the following principles for a Feature-based approach in the architectural context. Features in mechanical engineering are used mainly to describe the lowest level of detail in a product's design, namely the characteristics of its parts. In architecture the design process does not normally follow a strictly hierarchical approach and therefore requires that the building be modelled as a whole. This implies that multiple levels of abstraction are modelled and that Features are used to describe information at the various abstraction levels. Furthermore, architectural design involves concepts that are non-physical as well as physical; Features are to be used for modelling both kinds. The term Feature is defined in this research project to reflect the above key-concepts for this modelling approach. A Feature is an autonomous, coherent collection of information, with semantic meaning to a designer and possibly emerging during design, that is defined to formalise a design concept at any level of abstraction, either physical or non-physical, as part of a building model. Feature models are built up entirely of Features and are structured in the form of a directed graph. The nodes in the graph are the Features, whereas the arcs are the relationships between the Features. Features can be of user-defined types and incidental relationships can be added that are not defined at the typological level. An inventory in this project of what kind of information is involved in the practice of modelling architectural design is based on the analysis of a selection of sources of architectural design information. This inventory is deepened by a case study and results in the proposition of a categorisation of architectural Feature types.

title	A Virtual Reality User Interface for a Design Information System, CCAI: the Journal for the Integrated Study of Artificial Intelligence
source	Cognitive Science and Applied Epistemology, Rijks Universiteit Gent
summary	The computer is a tool, a complex artefact that is used to extend our reach. A computer system can provide several kinds of services, but against these services stands a supplementary task that the user must deal with: the communication with the computer system. We argued that Virtual Reality (VR) can fundamentally improve the user interface by rendering on the common experiential skills of all users. We present the theoretical basis for this, referring to Donald Norman's theory. We show that VR provides at least theoretically, the means to take a big step in the direction of an ideal user interface. As an example of a innovative application of VR in user interface design, we presented the VR-DIS system; an interdisciplinary design system for the building and construction industry. We discuss the issues underlying the design of its VR interface.

title	Integrating Databases, Objects and the World-Wide Web for Collaboration in Architectural Design
source	Proceedings of the focus symposium: World Wide Web as Framework for Collaboration in conjunction with the 11th International Conference on Systems Research, Informatics and Cybernetics, The International Institute for Advanced Studies in Systems Research
summary	Architectural design requires specialized vertical knowledge that goes beyond the sharing of marks on paper or the multi-casting of video images. This paper briefly surveys the state-ofthe- art in groupware and outlines the need for vertical and integrated support of synchronous and asynchronous design collaboration. The paper also describes a software prototype (WebOutliner) under development that uses a three-tier persistent object-oriented, web-based technology for a richer representation of hierarchical architectural artifacts using Apple’s WebObjects technology. The prototype contributes to earlier work that defined a framework for a shared workspace consisting of Participants, Tasks, Proposals, and Artifacts. These four elements have been found through observation and analysis to be adequate representations of the essential components of collaborative architectural design. These components are also hierarchical which allows users to filter information, copy completed solutions to other parts of the program, analyze and compare design parameters and aggregate hierarchical amounts. Given its object orientation, the represented artifacts have built-in data and methods that allow them to respond to user actions and manage their own sub-artifacts. In addition, the prototype integrates this technology with Java tools for ubiquitous synchronous web-based access. The prototype uses architectural programming (defining the spatial program of a building) and early conceptual design as examples of seamlessly integrated groupware applications.

title	XML for Flexibility an Extensibility of Design Information Models
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	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title	Immersive Redlining and Annotation of 3D Design Models on the Web
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 81-98
summary	The Web now enables people in different places to view three-dimensional models of buildings and places in a collaborative design discussion. Already design firms with offices around the world are exploiting this capability. In a typical application, design drawings and models are posted by one party for review by others, and a dialogue is carried out either synchronously using on line streamed video and audio, or asynchronously using email, chat room, and bulletin board software. However, most of these systems do not allow designers to embed annotations and proposed design changes in the threedimensional design model under discussion. We present a working prototype of a system that has these capabilities and describe the configuration of Web technologies we used to construct it.

title	Augmented Reality Design Decision Support Engine for the Early Building Design Stage
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 231-240

summary	Augmented reality has come a long way and experienced a paradigm shift in 1999 when the ARToolKit was released as open source. The nature of interaction between the physical world and the virtual-world has changed forever. Fortunately for the AECO industry, the transition from traditional Computer Aided Design to virtual building design phrased as Building Information Modeling has created a tremendous potential to adopt Augmented Reality. The presented research is situated in the early design stage of project inception and focuses on supporting informed collective decision-making, characterized by a dynamic back and forth analytical process generating large amounts of data. Facilitation aspects, such as data-collection, storage and access to enable comparability and evaluation are crucial for collective decision-making. The current research has addressed these aspects by means of data accessibility, visualization and presentation. At the core of the project is a custom developed Augmented Reality framework that enables data interaction within the design model. In order to serve as a collaborative decision support engine, the framework also allows multiple models and their datasets to be displayed and exercised simultaneously. The paper demonstrates in the case study the successful application of the AR tool during collaborative design decision meetings.

title	Virtual Heritage: Is There a Future for the Past?
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 482-487
summary	This paper attempts an overview of the contribution which emerging information technologies - viz CAD, Multimedia, Virtual Reality and the Internet - can make to the presentation, understanding and preservation of the rich architectural heritage which exists (pro-term) in almost every cultural context. In the UK, the growing interest in sites such as Stonehenge has, through the threat of greater physical presence, increasingly kept the public at bay - a curious paradox which Virtual Reality (VR) has the potential to address. Virtual Reality (-an overly used and underly understood term-) is an information technology which can provide a convincing experience of environments which: i) exist, but are too remote, costly or hazardous, to visit. ii) don't yet exist but are planned, such as architectural designs or urban plans. iii) never will exist, other than in the imagination. iv) existed in the past and are now threatened or already lost. // This paper has its focus on the latter category, i.e. what is now becoming known as Virtual Heritage (VH), but it puts VH in the context of the broader spectrum of simulated experiences of past, present and future environments of cultural significance. The paper draws largely on the work of ABACUS, the Architecture and Building Aids Computer Unit, Strathclyde. The examples of the application of IT to VH include: i) a virtual reality experience of Historic Scotland's premier historical site: Skara Brae, the most complete neolithic settlement in Northern Europe. ii) a multimedia CD-ROM featuring some 50 of the most wonderful interiors of Glasgow's architectural treasures. iii) a computer based archive of rare and normally inaccessible 17C and 18C drawings of Scottish buildings from three seminal sources. iv) a massive 3-D model of Glasgow (some 10,000 buildings located on the hilly terrain of the city), which is now accessible on the Internet. // The paper concludes with conjectures based on the examples given of how emerging information technologies can help secure a future for the past.

doi	https://doi.org/10.52842/conf.acadia.1999.138
summary	One of the most consistent, powerful and philosophical ideas which has run like a silk thread through the short and erratic history of the development of computer aided architectural design is that of user participation in the design decision-making process. It is not an idea with which the architectural profession is particularly comfortable but it is, the authors claim, one which is central to the professional ethic and, therefore, to its ultimate survival. Design decision-making is, if addressed properly, a hugely, complex multi-variety, multi-person process on which precious little serious research has been focused. In the late 1960's the Design Methods Group in the USA and the Design Research Society in the UK formulated paper-based models of the design process and anticipated, in some regards with un-nerving accuracy, the way in which the application of information technologies would impinge beneficially on the process of design decision-making and, therefore, on the quality of the built environment. One concept expressed at that time was as follows: (•) the application of computers to the modeling and prediction of the cost and performance behavior of alternative design solutions allows subjective value judgements to be better informed and more explicitly audited, and that (•) such subjective value judgements should be made by those most affected by them, i.e. the future owners and users of buildings. // This paper is devoted to the critical re-examination of this concept, on the seminal research and development which has kept the notion alive over 30 years, and, most importantly in the context of the theme of ACADIA 1999, how the current advances in multimedia, virtual reality and internet access are not yet making its ubiquitous adoption inevitable: in short, a plea for Media in Mediation.

title	Integration and Application of Technologies CAD in a Regional Reality - Methodological and Formative Experience in Industrial Design and Products Development
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 295-297
summary	The experience to present is begun and developed during the academic year 1998, together to the course of IV pupils level of the Industrial Design career in the Universidad del Bío-Bío, labor that I have continued assuming during the present year, with a new youths generation. We have accomplished our academic work taking as original of study and base, the industrial and economic situation of the VIII Region, context in the one which we outline and we commit our needs formative as well as methodological to the teaching of the discipline of the Industrial Design. Consequently, we have defined a high-priority factor among pupils and teachers to reach the objectives and activities program of the course, the one which envisages first of all a commitment of attitude and integrative reflection among our academic activity and the territorial human context in the one which we inhabit. In Chile the activity of the industrial designer, his knowledge and by so much his capacity of producing innovation, it has been something practically unknown in the industrial productive area. However, the current national development challenges and the search by widening our markets, they have created and established a conscience of the fact that the Chilean industrial product must have a modern and effective competitiveness if wants be made participates in segments of the international marketing. It is in this new vision where the design provides in decisive form to consider and add a commercial and cultural value in our products. To the university corresponds the role of transmitting the knowledge generated in his classrooms toward the society, for thus to promote a development in the widest sense of the word. Under this prism the small and median regional industry in their various areas, have not integrated in the national arrangement in what concerns to the design and development of new and integral products. The design and the innovation as motor concept for a competitiveness and permanency in new markets, it has not entered yet in the entrepreneurial culture. If we want to save this situation, it is necessary that the regional entrepreneur knows the importance of the Design with new models development and examples of application, through concrete cases and with demands, that serve of base to demonstrate that the alliance among Designer and Industry, opens new perspectives of growth upon offering innovation and value added factors as new competitiveness tools. Today the communication and the managing of the information is a strategic weapon, to the moment of making changes in a social dynamics, so much at local level as global. It is with this look that our efforts and objective are centered in forming to our pupils with an integration speech and direct application toward the industrial community of our region, using the communication and the technological information as a tool validates and effective to solve the receipt in the visualization of our projects, designs and solutions of products. As complement to the development of the proposed topic will be exhibited a series of projects accomplished by the pupils for some regional industries, in which the three dimensional modeling and the use of programs vectoriales demonstrate the efficiency of communication and comprehension of the proposals, its complexity and constructive possibilities.

title	Information Sharing in Building Design
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 165-183
summary	We address information modeling and exchange in asynchronous, distributed collaboration between software applications or design agents that are heterogeneous, that is, developed independently based on application- specific data models. We identify the requirements an integration environment must satisfy if it is to support the semantically correct exchange of selected, locally generated information between the agents. These requirements are distilled from both the literature and our own experiments with the Object Modeling Language OML. The resulting requirements were then formalized into an information modeling and exchange environment constructed around the modeling language called SPROUT (supported by a compiler) and an associated software architecture that can be targeted toward many different hardware and software platforms. A unique capability supported in this environment is formal support for integrating existing applications: Given a schematic description in SPROUT, a formal specification can be used to generate computer programs that provably map data to and from the applications.

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.

summary	Intemet technologies provide opportunities for improving the delivery of facility information to building owners and operators. Discussions with facility operators have led to identification of problems in current practices of delivering facility information using as-built drawings. A Web-based software prototype illustrates how facility information can be automatically structured into documents that support specific facility operations tasks.

title	The Front of the Stage of Vitruvius' Roman Theatre - A new Approach of Computer Aided Design that Transforms Geometric Operators to Semantic Operators
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 321-333
summary	The driving force of all researches where the systems of computation are used, is the utilization of an intelligent method for the representation of building. The use of computer, in design process, is often limited to technical functions (tekhne), and what one usually calls computer-aided design is often no more than computer-aided drawing. In this research paper we continue a reflection on the architect's work methods, and suggest an approach to design based on the semantic properties of the object (i.e. semantic operators), rather than by geometric operators. We propose a method of computer aid design using procedural models where the initial state of design is vague and undefined. We operate from a paradigm that leads to represent a building by means of parametric functions that, expressed algorithmically, give a procedural model to facilitate the design process. This approach opens new avenues that would permit to add the logos (semantic properties) and lead to a metaphorical representation. By means of procedural models, we show that, from a generic model we can produce a four dimensional model that encapsulate a volumetric model with semantic characteristics. We use a meta-functional language that allows us to model the actions and encapsulate detailed information about various building elements. This descriptive mechanism is extremely powerful. It helps to establish relations between the functions, contributes to a better understanding of the project's aim, and encapsulates the building properties by recalling characteristics of common classes which give rise to a new configuration and a completely original design. The scientific result of this experiment is the understanding and confirmation of the hypothesis that it is possible to encapsulate, by means of computing process, the links between design moves during conceptual and figural decisions and transform the geometric operators in semantic operators.

title	Anticipating Reuse: Documenting Buildings for Operations Using Web Technology
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 54-65
doi	https://doi.org/10.52842/conf.acadia.1999.054
summary	This research explores the feasibility of Web technology as a means for delivering building information to better support facility operations. Our research proposes just-in-time (JIT) facility documentation as a pragmatic solution to the limitations of current as-built documents, allowing more effective reuse of building information. Our investigation addresses four issues: 1) what building information is needed for facility operations; 2) how the design and construction team can improve the format for delivering the building information to facility operators; 3) how current Web technology can store and deliver facility information in support of operations; 4) what is the mechanism of documenting building information using the Web technology. // We surveyed literature, interviewed members of design and operations teams and reviewed current initiatives of industry and software vendors to identify problems with current practices. We also surveyed promising Web technologies and conducted experiments to determine how these technologies could help to solve the problems. We constructed a conceptual framework of JIT facility documentation as a solution to current information fragmentation problems. We developed a prototype of the JIT document system to demonstrate a “proof of concept” by using current Web technologies such as Autodesk’s DWF, Microsoft’s Active Server Pages, VB and Java script, and Access database to develop the prototype system. By dynamically composing HTML pages in response to task-specific requests, our prototype enables easy access and integration of a variety of building information to support facility operations.

title	Integration of design and construction through shared objects in the CO-CIS project
source	CIDAC, Volume 1 Issue 1 May 1999, pp.
summary	This paper presents an Integrated Building Project Model (IBPM) which provides the basis on which software applications can share objects and shows how integration is achieved at the conceptual level. It is used to develop a pure object-oriented database server which acts as a central object repository, and facilitates the sharing of objects between multiple applications. The IBPM provided the basis for the development of the COllaborative Construction Integrated System (CO-CIS) based on the principles of client/server computing and utilising dynamic common object sharing in real-time between CAD and project management packages. The work demonstrates the capabilities of pure object technologies and should encourage industry to adopt the approach and facilitate the development of the common information standards.

title	Standards media and methods
source	Automation in Construction 8 (4) (1999) pp. 473-479
summary	The global marketplace and advances in information technologies are leading to great changes in standards. These include growing reliance on international standards, new standards-development techniques, and new media and environments in which standards are expressed. Both general and project-specific information are being stored in and accessed from distributed, electronic, object-oriented databases. Standards available from general-purpose information systems will be capable of accessing and processing data to evaluate compliance with their provisions. Such standards will be convenient and efficient: input data will be accessed automatically from pertinent fields of the general and project-specific databases; results of evaluations will be recorded automatically in the project-specific database and used in decisions affecting design, construction or operation of constructed facilities. Major uses of standards will be associated with computer-aided systems and major revenues from uses of standards will accrue to systems developers and users. Standards-developing organizations should respond to this marketplace by themselves producing standards in the form of executable objects. Computer aids can assist in the formulation and expression of standards that are complete in coverage of the intended scope, consistent and unambiguous in their logic, and correct in reproducing the intent of the formulators.

title	Virtual Reality in Architectural Education: Defining Possibilities
source	ACADIA Quarterly, vol. 18, no. 4, pp. 7-9
doi	https://doi.org/10.52842/conf.acadia.1999.007
summary	Introduction: virtual reality in architecture Virtual Reality (VR) is an emergent computer technology for full 3D-simulations, which has a natural application in the architectural work, due that activity involves the complete definition of buildings prior to its construction. Although the profession has a long tradition and expertise in the use of 2D-plans for the design of buildings, the increasing complexity of projects and social participation requires better media of representation. However, the technological promise of Virtual Reality involves many sophisticated software and hardware developments. It is based on techniques of 3D-modelling currently incorporated in the majority of drawing software used in architecture, and also there are several tools for rendering, animation and panoramic views, which provide visual realism. But other capabilities like interactivity and sense of immersion are still complex, expensive and under research. These require stereoscopic helmets, 3D pointers and trackers with complicated configurations and uncomfortable use. Most advanced installations of Virtual-Reality like CAVEs involve much hardware, building space and restrictions for users. Nevertheless, diverse developers are working in Virtual-Reality user-friendly techniques and there are many initial experiences of architectural walk-throughs showing advantages in the communication and development of designs. Then we may expect an increasing use of Virtual Reality in architecture.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.
