title	Visualisation for Clients - One Example of Educating CAAD for Practice
doi	https://doi.org/10.52842/conf.ecaade.1996.017
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 17-24
summary	During the spring term 1996, 13 students of the 3rd and 4th year at the School of Architecture at Lund University had the opportunity to make a one semester CAAD project. 11 students chose the individual exercise to use computer media for developing a small architectural design in interaction with a client. The focus was set more on visualization and the process of communicating ideas, feelings and practical solutions between architect and client and visa versa rather than concentrated on the final product. This paper describes the process of the project and the reflections of the participants. It will discuss problems from the teachers point of view.

title	An integrated system for computer-aided design and construction of reinforced concrete buildings using modular forms
source	Automation in Construction 5 (4) (1996) pp. 323-341
summary	The study reported in this paper investigates the feasibility of automating the on-site construction of reinforced concrete residential buildings. The basic construction tasks are identified, analyzed and modified with a view towards potential for automation. Emphasis is placed on developing modular forms that facilitate automation. The majority of work in the field of construction robotics has focused on the adaptation of existing industrial robots to automate traditional construction processes. This paper outlines a computer-aided construction system approach specially suited for integrating design and implementation by on-site robots. A Computer-Integrated Construction (CIC) system, similar to CIM, is developed that includes a CIC data-base, a construction design system, a construction production/process planning system, and a robotics execution system. This approach is intended to minimize the redesign effort as well as the need for on-site manual work.

title	A knowledge-based model for developing location strategies in a DSS for retail planning
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Most DSS for retail planning are based on impact assessment models to support the evaluation of plan scenario's. This paper introduces a complementary knowledge-based model to support also the earlier stage of formulating plan scenario's. An analysis of the retail planning problem reveals the main lines of the strategies adopted by most Dutch planners and retailers to achieve their goals. A basic strategy that seems to be appropriate in most problem contexts is formulated in the form of a set of decision tables. Each decision table or system of decision tables specifies for a problem area decision rules to identify and analyse problems and to formulate possible actions. The model is implemented in a DSS where it is used in combination with quantitative impact assessment models. A case study in the area of daily good facilities demonstrates the approach. The major conclusion is that the knowledge-based approach and in particular the decision table technique provides interesting possibilities to implement planning task structures in a DSS environment.

title	CAD usage in an architectural office: from observations to active assistance
source	Automation in Construction 5 (3) (1996) pp. 243-255
summary	The functionality and resources provided by CAD systems have been increasing rapidly, but productivity growth expected from their use has been difficult to achieve. Although many surveys describe this productivity puzzle, few studies have been conducted on actual CAD users to understand its causes. In an effort to arrive at such an understanding, the first author visited a federal architectural office and observed CAD users in their natural setting. This paper describes preliminary results obtained from the study, which used ethnographic techniques developed by cultural anthropologists. The study revealed that users had leveled-off in their learning and experimentation and were using the CAD system in suboptimal ways. By asking why users were not using many resources available to them to improve performance, the observer uncovered issues of communication and management that needed to be addressed. Based on this understanding, the authors provide explicit recommendations to CAD users and vendors. In addition, they hypothesize that users might benefit from a system that provides active assistance, that is, intervenes spontaneously with advice, assistance, and relevant information while the user interacts with the CAD system. They conclude with some issues revealed by the study that should be considered when developing such active assistance.

title	Knowledge-based System to Support Architectural Design - Intelligent objects, project net-constraints, collaborative work
doi	https://doi.org/10.52842/conf.ecaade.2001.080
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.

title	Design Modeling With Shape Algebras and Formal Logic
doi	https://doi.org/10.52842/conf.acadia.1996.099
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 99-113
summary	A new method of describing designs by combining the paradigms of shape algebras and predicate logic representations is presented. Representing shapes and spatial relations in logic provides a natural, intuitive method of developing complete computer systems for reasoning about designs. The advantages of shape algebra formalisms over more traditional representations of geometric objects are discussed. The method employed involves the definition of a large set of high level design relations from a small set of simple structures and spatial relations. Examples in architecture and geographic information systems are illustrated.

title	Put: Language-Based Interactive Manipulation of Objects
source	IEEE Computer Graphics and Applications
summary	Describing a scene to a computer is an inherent task of computer graphics applications. Modeled scenes are typically built with direct placement techniques or specialized scripting languages. The scene description task could be greatly eased if natural language were an interactive control option. However, natural language understanding is notoriously difficult for computers. This difficulty is exacerbated in the case of computer graphics by the need for geometric output, not just "conceptual understanding" or high-level inferencing. General text-understanding techniques have not been successfully applied to scene generation. Typically, a few task-specific commands, such as "walk," are implemented as an ad-hoc collection of procedures. Our approach aims to separate the expressive power of fundamental natural concepts from the difficult task of text understanding. We are developing a 3D object placement system based on a combination of natural commands and interactive techniques. Guided by research in cognitive linguistics, we use basic spatial relationships--such as in, on, and at--and fundamental scene parameters--such as viewer location and object dimensionality--to identify regions of placement for objects in a scene. These natural commands can be used to quickly prototype a complex scene and constrain object placement.

title	Report on Computers in Practice: A survey of computers in architectural practice
source	UK: University of Edinburgh
summary	This is a report on the dynamic relationship between information technology (IT) and architectural practice. The report summarises the attitudes and opinions of practitioners gathered through extensive recorded interviews, and compares these attitudes and opinions with the findings of other studies. The report is compiled from the point of view of an understanding of appropriating as preceding as the model for understanding. We thereby connect what is going on in IT with concepts currently under discussion in postmodern thought and in the tradition of philosophical pragmatism. We identify several of the major options identified by practitioners in their use of IT, including practicing without computers, substituting computers for traditional tasks, delivering traditional services in an innovative way through IT, and developing new services with IT. We also demonstrate how firms are changing and are being shaped by the market for architectural services. One of the major areas of change is in how IT and related resources are managed. We also consider how the role of the practitioner as an individual in a firm is changing along with changes in IT, and how different prognoses about the future of IT in practice are influenced by certain dominant metaphors. Our conclusion is that IT is best understood and appropriated when it is seen as fitting into a dynamic field or constellation of technologies and practices. Such an orientation enables the reflective practitioner to confront what is really going on as IT interacts with practice. praxis- practice theory

title	The Continuing Dichotomy: Practice vs. Education
doi	https://doi.org/10.52842/conf.ecaade.1996.131
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 131-142
summary	While it is apparent from the architectural literature that some practices are innovative in their use of computers for architectural design, clear evidence indicates that most architectural practices have applied computing to traditional practice paradigms. Information technology is therefore being applied to practice systems which were in place prior to computers being available. This has significant implications for architectural education in which there is tension developing between the requirements of the commercially oriented architectural practice and the innovation driven computer-aided architectural design educator. The first wishes to equip graduates for immediate and productive employment in computerised architectural practices and may be loosely interpreted as a graduate’s ability to work as a CAD operator within an architectural practice environment. The second has the desire for students to be innovative in their use of information technology as an aid in informing and evaluating parts of both the design process and its outcomes. However, it is only when both architects and educators identify the architectural process as an integrated information system that these tensions can be resolved. This requires reconsideration of the function and use of information technology in both educational institutions and in architectural practices. The paper discusses how fruitful this can be in the current environment and outlines current developments at Deakin University which aim at providing a middle ground

title	Modeling construction processes using artificial neural networks
source	Automation in Construction 4 (4) (1996) pp. 307-320
summary	The paper evaluates a neural network approach to modeling the dynamics of construction processes that exhibit both discrete and stochastic behavior, providing an alternative to the more conventional method of discrete-event simulation. The incentive for developing the technique is its potential for (i) facilitating model development in situations where there is limited theory describing the dependence between component processes; and (ii) rapid execution of a simulation through parallel processing. The alternative ways in which neural networks can be used to model construction processes are reviewed and their relative merits are identified. The most promising approach, a recursive method of dynamic modeling, is examined in a series of experiments. These involve the application of the technique to two classes of earthmoving system, the first comprising a push-dozer and a fleet of scrapers, and the second a loader and fleet of haul trucks. The viability of the neural network approach is demonstrated in terms of its ability to model the discrete and stochastic behavior of these classes of construction processes. The paper concludes with an indication of some areas for further development of the technique.

title	Awareness Space in Distributed Social Networks
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary	In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

title	Development of interior finishing unit assembly system with robot: WASCOR IV research project report
source	Automation in Construction 5 (1) (1996) pp. 31-38
summary	The WASCOR (WASeda Construction Robot) research project was organized in 1982 by Waseda University, Tokyo, Japan, aiming at automatizing building construction with a robot. This project is collaborated by nine general contractors and a construction machinery manufacturer. The WASCOR research project has been divided into four phases with the development of the study and called WASCOR I, II, III, and IV respectively. WASCOR I, II, and III finished during the time from 1982 to 1992 in a row with having 3-4 years for each phase, and WASCOR IV has been continued since 1993. WASCOR IV has been working on a automatized building interior finishing system. This system consists of following three parts. (1) Development of building system and construction method for automated interior finishing system. (2) Design of hardware system applied to automated interior finishing system. (3) Design of information management system in automated construction. As the research project has been developing, this paper describes the interim report of (1) Development of building system and construction method for automated interior finishing system, and (2) Design of hardware system applied to automated interior finishing system.

title	A Site-Based Computerized Production Planning & Control Model for The Plants which Produce Prefabricated Building Components
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	The "open systems" in building prefabrication may be qualified more flexible to some extent compared to the closed ones and may use the tools and approaches used in industrial production areas for the estimation of demand and production. As for the closed systems in particular, it is not possible for these systems to apply this kind of approach. Their production must be based on absolutely assured demands and projects. Because of this, they need detailed projects and assembly schedules for produc-tion. As a result of this, their production modes can be qualified "custom-made" type and production planning functions must provide the demand values from the assembly schedules of contracted proj-ects. The problem can be solved by integrating the work schedules of the sites that are served by fac-tory. Integration of data on a computerized system will be preferable and it is possible to realize the model in two alternative ways. The first is developing a new conceptual model and convert it into a software and the second is developing an approach for customizing general purpose project planning and programming software for using them in production planning. The second solution is studied in the paper following this. The aim of this study is to develop the principals of a conceptual model for an Integrated Data Flow and Evaluation System for production planning in prefabrication and to con-vert this model into an applicable and objective computer-aided model.

title	Matching the Knowledge Needs of Trade and Industry: Advanced and Operational Knowledge Based Systems
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Complex tasks that are being performed in trade and industry such as diagnosis, engineering and planning, increasingly require rapid and easy access to large amounts of complicated knowledge. To cope with these demands on trade and industry, advanced automated support for managing knowledge seems to be needed. Knowledge based systems are claimed to match these needs. However, to deal with the vast volume and complexity of knowledge through knowledge based systems, preconditions at three computer systems levels should be fulfilled. At the first level, called the knowledge level, the development of knowledge based systems requires a well-elaborated theory of the nature of knowledge that helps to get a clear and consistent definition of knowledge. By providing guidelines for selecting and developing methodologies and for organising the mathematical functions underlying knowledge representation formalisms, such a definition significantly advances the process of knowledge engineering. Here, we present the theory of functional object-types as a theory of the nature of knowledge. At the second level, called the symbol level, the representation formalisms used must be compatible with the chosen theory of the nature of knowledge. The representation formalisms also have to be interpretable as propositions representing knowledge, so that their knowledge level import can be assessed. Furthermore, knowledge representation formalisms have to play a causal role in the intelligent behaviour of the knowledge based system. At the third level, called the systems level, a knowledge based system should be equipped with facilities that enable an effective management of the representation formalisms used. Yet other system facilities are needed to allow the knowledge base to communicate with existing computer systems used in the daily practice of trade and industry, for instance Database Management Systems, Geographical Information Systems and Computer Aided Design Systems. It should be taken into account that these systems may run in different networks and on different operating systems. A real-world knowledge based system that operates in the field of soil contamination exemplifies the development of an advanced and operational knowledge-based system that complies with the preconditions at each computer systems level.

title	Developing case-based reasoning for structural design
source	IEEE Expert
summary	Case-based systems enable users to retrieve previously known designs from memory and adapt them to fit the current design problem. The four case-based design systems described here illustrate how various implementations achieve design assistance or design automation objectives. Case-based reasoning is a problem-solving technique that makes analogies between a problem and previously encountered situations (cases) relevant to solving the problem. Using CBR as a design process model involves the subtasks of recalling previously known designs from memory and adapting these design cases or subcases to fit the current design context. The detailed development of this process model for a particular design domain proceeds in parallel with the development of the case representation, the case memory organization, and the necessary design knowledge. The selection of an information representation paradigm and the details of its use for a problem-solving domain depend on the intended use of the information, the project information available, and the nature of the domain. CBR could be used to develop and implement a CBR system. Although that sounds circular, if CBR is a viable approach to problem solving, it can be applied to the development of the reasoning system itself. Toward that end, this article presents four "cases" of case-based building design systems that we've developed at the University of Sydney: CaseCAD, CADsyn, Win, and Demex. These systems exemplify alternative case memory contents and organizations and provide insight into different potential implementations of the recall and adaptation subprocesses.

title	A history and application of visual simulation in which perceptual behaviour movement is measured.
source	Architectural and Urban Simulation Techniques in Research and Education [3rd EAEA-Conference Proceedings]
summary	For our research on perception and judgment, we have developed a new visual simulation system based on the previous system. Here, we report on the development history of our system and on the current research employing it. In 1975, the first visual simulation system was introduced, witch comprised a fiberscope and small-scale models. By manipulating the fiberscope's handles, the subject was able to view the models at eye level. When the pen-size CCD TV camera came out, we immediately embraced it, incorporating it into a computer controlled visual simulation system in 1988. It comprises four elements: operation input, drive control, model shooting, and presentation. This system was easy to operate, and the subject gained an omnidirectional, eye-level image as though walking through the model. In 1995, we began developing a new visual system. We wanted to relate the scale model image directly to perceptual behavior, to make natural background images, and to record human feelings in a non-verbal method. Restructuring the above four elements to meet our equirements and adding two more (background shooting and emotion spectrum analysis), we inally completed the new simulation system in 1996. We are employing this system in streetscape research. Using the emotion spectrum system, we are able to record brain waves. Quantifying the visual effects through these waves, we are analyzing the relation between visual effects and physical elements. Thus, we are presented with a new aspect to study: the relationship between brain waves and changes in the physical environment. We will be studying the relation of brain waves in our sequential analysis of the streetscape.

title	Form Processing: A System for Architectural Design
source	Harvard University
summary	This thesis introduces a new approach to developing software for formal synthesis in architectural design. It presents theoretical foundations, describes prototype specifications for computable implementation, and illustrates some examples. The approach derives from the observation that architects explore ideas through the use of sequences of drawings. Architects derive each drawing in a sequence from its predecessor by executing some transformation on a portion of the drawing. Thus, a formal design state is established by a sequence of drawings with historical information about their construction through progressive transformations. The proposed system allows an architect to develop a design in three ways. First, a new transformation can be added to a current sequence of drawings. Second, existing sequences can be edited by exchanging their subset sequences. Third, an existing sequence can be revised parametrically by assigning new values to its design variables. The system implements scripts that specify categories of shapes and transformations between any two shape categories. When an instance of a shape category is found in a design, a transformation can replace it with an instance of another shape category. Recursive application of a given set of transformations to an initial shape instance produces a sequence of drawings that represents a formal design state. The system encodes this formal design state as an assembly of all the shape instances used and their relationships (nesting, emergent and replacement). Furthermore, this assembly, called a construction graph, allows the existing sequences to be edited efficiently by exchanging subsets and to be revised parametrically. The advantage of this approach as demonstrated in the examples is that it allows intuitive, rapid and interactive construction of complex designs. Moreover, design knowledge can be captured by scripts that depict heuristic shapes and transformations as well as by assembled construction graphs which depict cases of formal design. Such a reusable and expandable knowledge base is essential for assisting disciplined and creative architectural design.
