title The Profits of CAAD Can Be Increased by an Integrated Participatory Design Approach
source Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 53-57
summary Computer-aided Architectural Design is understood in Poland as comprising all computer applications in an architectural design office. In Polish architectural practice (with a few exceptions) it is still under theoretical consideration and in an experimental phase. Therefore if we are talking about the future of CAAD in Poland we are thinking about a much more long-term future than for Western countries. However, if new economic and organizational changes initiated in Poland in the early 1980s continue, future problems and solutions in CAAD will, for us, become similar to those in Western countries.

title Computer Aided Dimensional Control in Building Construction
source Eindhoven University of Technology
summary Dimensional control in the building industry can be defined as the operational techniques and activities that are necessary, during the construction process of a building, for the assurance of the defined dimension quality of a building (Hoof, 1986). Efficient and precise dimensional control of buildings under construction is becoming ever more important because of changes in the construction industry. More prefabricated components are used; more regulations appear; newly designed buildings have more complex shapes, and building construction is speeding up. To ensure the predefined dimensional quality, a plan of dimensional control must be designed, on the basis of building drawings and specifications delivered by architects, before the building is constructed. The dimensional control plan must provide site personnel with adequate information on, among others, setting out and assembling building components, which can often be done by means of Total Stations. The essence of designing a dimensional control plan is to find out which points should be used as positioning points, which points should be set out in advance or controlled afterwards, and not to forget why. In an effort to contribute to the improvement of the dimensional control of on-site construction projects, this research tries to capture the knowledge required to design an adequate dimensional control plan and make that knowledge more generally available, and build a digital connection between CAD systems and Total Stations, focusing on prefabricated concrete building structural elements. The instrument developed in this research for capturing of essential dimensional control information and knowledge makes use of Product Data Technology (PDT) and Knowledge Technology (KT). The chosen solution supports the stochastic analysis of optimal positioning points taking account of various sorts of deviations and their mutual relationships. The resulting information model has been written in a standardized information modelling language called UML (Unified Modelling Language). The model has been implemented in a Dimensional Control System (DCS) and applied in the “La Tour” construction project in Apeldoorn, the Netherlands. The DCS provides a digital way to bridge the floor plan design with dimensional control, predict dimensional deviation limits and output the data needed for a Total Station. The case study of “La Tour” tests the UML model and prototype of the DCS. The results prove that direct positioning of objects (by putting reflectors on the objects and using a Total Station and by inputting coordinates extracted and calculated from the AutoCAD drawings) provides higher speed, accuracy and reliability. It also shows a way to (pre)position free form objects in 3D where traditional methods cannot. In conclusion: (1) it seems to be justified to expect that the application of the DCS will contribute to increased confidence in dimensional control and the reduction of costs of failure, which potentially could support the increased use of cheaper construction methods, and will also contribute to the improvement of building design and construction process. (2) the scientific contribution of this research is a first step towards providing dimensional quality in a construction process covered by stochastic dimensional uncertainty, even for positioning of free form objects.

summary We have grown accustomed to performing elaborate queries on textual data, e.g. via online search engines, file system managers and word processors. In the past decade, retrieval methods that also work on non-textual data have become mainstream (e.g. face recognition software). Sadly, these developments have so far not caught on for data mining within geometrical data, e.g. 3D meshes generated in the course of architectural work. Specifically during data exchange, such a search functionality would be handy, as it often happens that geometry is exported but object identity is lost - think, for example, of generative geometry or exported BIM data. In this paper, we present an example of such a search functionality, based on angular search. Our method is inspired by regular expressions, a string matching technique commonly employed for matching substrings.

title Strategic Decision Support: Using Neural Networks to Enhance and Explore Human Strategizing
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper focuses on a mechanism by which planners and designers are thought to reduce complexity. The mechanism involves choosing a potentially profitable direction of search, or choosing potentially profitable set of aims to pursue, within which a detailed solution might be found, and rejecting all potentially unprofitable directions of search. The literature of psychology, planning and operations research is drawn upon to argue that designers base such initial choice of direction on their candidate aims' relative scores for eight key parameters: probability, returns for effort, delay, robustness, difficulty, present satisfaction and dependence. The paper then describes a piece of decision support software which, by eliciting any user's scores for their candidate aims on the eight key parameters, is able to order such aims into a strategic plan. Such software also incorporates a simulated neural network which attempts to "learn", from users' recorded responses to the software-suggested strategies, how users actually weight the relative importances of the eight key parameters. That is, it is hoped that the neural network will "converge' to some prototypical pattern(s) of weightings. Having such a tool would certainly constitute an advance in the state of the art of computer-aided strategy development. Alternatively, if the network never converges, the use of neural networks in computer-aided planning is perhaps not advisable. Accordingly, a test was conducted in which a group of planners used the software to address a typical spatial problem. The results, in terms of whether or not the neural network converged, will be reported.

summary Gulou is a type of building found in ethnic Dong people’s settlements in south west China. It plays a significant role in the traditional Dong architecture and shows both social and technical values. In the near future the technique as an intangible culture heritage would face the risk of extinction because of globalization. The paper argues that the use of formal grammar and computer tools could help the preservation and learning of the design knowledge of Gulou Structure and develop Gulou designs which would be adapted to modern needs. A shape grammar called Gulou Structure Grammar (GSG) and its computer implementation are made to achieve the goals of capturing the design knowledge of Gulou structure, generating new Gulou designs and promoting the education of Gulou building techniques.

title A Decision Support System for Local Authorities in Malaysia
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Given the dynamic nature of urban development, if is particularly important to have a well conceived planning management activity which can serve as the eyes and ears of a large planning process, up-to-date and reliable. It provides monitoring and the surveillance of compliance with planning regulations and it serves as an easy warning system with regard to sources of shortfalls in the process of urban planning. Information is therefore needed at the local authority level to facilitate administrative procedures, policy planning and plan implementation. Also, the advent of corporate planning and the continued squeeze on local authority expenditure require local authorities to examine critically whether rational decisions are made. Against this background, this paper examines the functions of a local authority particularly in the context of planning and urban management. These and the types of data which support them provide the fundamental framework upon which a model of geographic data entities and their relationship is developed. Ultimately, it will be reasonable to assume that a local authority will have developed a GIS providing a complete local authority coverage of up-to-date and accurate information at the parcel base. Consequently, it will be used to assist planning decisions taking into account among other things, the current scenario of the proposed development, physical constraints and future impacts. Further, a customized menu driven user interface is developed to allow planners and decision makers to view and analyze the planning scenarios interactively before deciding on the final plan. The paper concludes with a discussion on problems encountered in the project namely data availability and organizational issues.

title Development Control System and GIS for Local Authority in Malaysia:A Case of Kuala Lumpur City Hall
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary This paper examines the functions of local authority particularly in the context of planning and development control. The process of development control involves a technique for the systematic compilation of expert quantitative analysis and qualitative assessment of a project's land use and development viability, including its effect on the surrounding area, andthe presentation of results in a way which enables the importance of the predicted results, and the scope for modifying or mitigating them, to be properly evaluated by the relevant decision making body before a planning application decision is rendered. Taking Kuala Lumpur as an example this paper will demonstrate the development of database and its application for development and building control. The application indicates that thefunctionality of GIS can be enhanced, i.e. by adding new model and analytical tools to existing systems and by using the GIS toolkit to best effect. Consequently it will be used to assist decision-making, taking into account among other things, the current scenarios of the proposed development, physical constraint and future impacts.

summary This paper investigates the design process of a performance based pavilion from concept towards construction phases, by challenging conventional form and fabrication techniques. The proposed project is considered as a temporary structure, located in Antalya, Turkey. A free-form structure and a parametrically defined cladding are designed to serve as an installation unit, a shading element and urban furniture. The pavilion geometry, performance assessments and proposed fabrication schemes are clearly described in the paper. The method integrates form, performance, material and fabrication constraints and exposes how environmental and structural performances, including Solar Access Analysis and Static Structural Analysis, may inform the design project.

title A Conceptual Model of a Computer Mediated Asynchronous Collaborative Design Environment
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary Architectural design practice is a collective work of different levels of expertise. Collaborative design relies on seamless meshing of specialists with different levels of expertise, skills and views. Research oncollaborative design suggests various methodologies for supporting synchronous or asynchronous communicative practices of designers in reviewing and analyzing design decisions at different stages of thedesign process. However, they do not address the provision of an action platform that would enable collaborative group decision making in architectural design. There are four requirements for this platform:1) sharing of design decisions among designers, 2) sharing of design rationale among designers, 3) detecting conflicts among design decisions, and 4) sharing of designers responses to design decisions. Thispaper presents a conceptual model of an asynchronous collaborative design environment that implements methodologies for addressing these requirements.

title Computer Mediated Collaborative Methodologies for Schematic Design Process
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary In architectural design practice, a number of design participants are involved in the schematic design process. Participants of the schematic design process perform collaboratively or individually conductedactivities at different stages of the design process. Research conducted on computer mediated architectural design systems suggests a variety of computerized methodologies to support participants in performingcollaborative activities during schematic design process. Most of the suggested methodologies are designed and ready to be implemented in specific platforms, and others are implemented and anticipated to beevaluated against the requirements of specific architectural design domains. However, there is still no single model to date that satisfactorily meets the requirements of collaborating participants duringschematic design process. Prospective users of the currently available models are obliged to choose among a vast variety of group design support solutions with little information about their potentials and pitfalls.This paper focuses on the identification of the fit between collaborating participants’ requirements, prospects of design activities and the currently developed computer mediated design paradigms. In this paper, the author discusses the findings of two different researches conducted in two different professional design domains, and identifies the type of actions prevalent to schematic design process. The author introduces an analysis of a number of computer mediated methodologies that are developed to support participants during schematic design process. As a result of this analysis, this paper introduces a classification of computer-mediated methodologies according to their potential support to tasks and activities performed during the schematic architectural design practice.

summary Design theories and film work with the same keywords since the designative concepts for both are time and space. At the beginning of the 20th century, the discovery of montage technique and a new esthetic language took place synchronically. This led to an interaction between them. Throughout the paper, this situation has been searched. However, the look is operational. For this reason, other discussions, concerning the topic have been excluded. The discussion is formed basically around four points defined in the 20th century. Four directors: Eisenstein, Tarkovski, Lynch and Greenaway are examined and discussed with their operational methods of filming. Various architects’ works are also searched and discussed with the same operational keywords. The paper aims to disclose the interaction between the topics.

title Virtual Shopping Centre Models and Path Choice
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary A three-dimensional computer model of a shopping center was navigated by participants who were unfamiliar with it. In the first experiment, an orthogonal and equally spaced grid was used. It was found that the great majority of the itineraries made simple and similar patterns which were remembered by the participants, although they often mistook theprecise path choices. In a second experiment, the width of the corridors was varied. Participants showed a distinct preference for wider corridors over narrow ones, resulting in a significantly different distribution of itineraries when compared with the results of the first experiment. Dimensional variation did not improve the ability of the participants toremember their itineraries, however. Also, individuals preferred to continue moving straight-ahead over turning. They also preferred to circumnavigate the shopping center, traveling along the outer edges, rather than head first into its center. The computer-based model is a low-cost way of testing preference in a dynamic way and could be mounted on multiple stations in computer laboratories as a way of increasing sample size. Thereremain some interface problems, however, that diminish somewhat the sensation of moving in real time. Further work will include refinements to the model and other variations in geometry and visual stimuli in the virtual shopping center, in addition to its validation in real environments.

summary In this paper we report on a recently started PhD project in which we investigate the extension of the concept of “Building Information Model” (BIM) to the domain of landscape design. The potential benefits of BIM in the field of architecture have been reported many times (e.g., Ibrahim et al., 2004; Eastman et al., 2008; Abdelmohsen et al., 2011). However, in landscape design an information model in the way of BIM seems to be missing. Benefits of a Landscape Information Model would be (a) formalisation of knowledge in landscape design; (b) information model to support multiple participants in landscape design; (c) improved information exchange between landscape design, architecture, and urban design. In this paper we set out the basic outline of the research.

summary The consciousness of identity, safety and identification of the individual in a social group, a nation or a place in which this person exists, can come into being and develop only if the continuing of tradition is secured. This continuing is in fact the person's indispensable and first need. It manifests itself especially through the cultural and spatial tradition of the person's own habitation, or more precisely - in the regional, native artistic expression of architecture.

It uses detailed mock-ups as vehicles to study, optimize, and evaluate the design as well as to provide feedback for student learning and the direction in which future designers may engage computational design. Finally, it investigates digital-to-physical design translations, the importance of which becomes more and more critical in the context of the current, computer-intensive architectural education and professional practice.

title From Drafting to Design: New Programming Tools are Needed
source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 253-261
summary The software needed by engineers and architects shows two new aspects. First, these programs get more and more graphic elements, secondly there is a trend from general purpose packages to more problem oriented programs. Comparing several of these application depending programs, a strong similarity appears; a user builds up a representation of a (technical) model by placing, replacing, deleting and so on, representations of objects, belonging to this model. From the programmer's point of view, it must be possible to abstract the several models and the actions on the components of a model, and therefore to build one-program with a model description as parameter. Assuming the existence of such a program, the only remaining part needed to build a complete dedicated package has reference to the specific technical calculations. In this contribution we touch on a number of the problems in developing and implementing such a program.

title Using Post-Occupancy Evaluation To AID Reflection in ConceptualDesign: Creating a Case-Based Design Aid For Architecture
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The design of large complex "real-world" objects such as buildings requires that the intentions of many potentially competing stakeholders be understood and reconciled. The process of conceptual design itself can be understood as a set of discourses among design team participants and between the designer and the design that gradually reveal these intentions and their relationships to design moves. Our goal is to aid this discourse by creating a Case-based Design Aid (CBDA) that provides design team participants access to specific evaluated cases of experience with previous buildings. This represents a merger of two sets of theories and methodologies: case-based reasoning (CBR) in artificial intelligence; and, post-occupancy evaluation (POE) in architectural research. In developing our CBDA, we have focused on several problems in architectural design: understanding the interactions between intentions, and making links between various modes of understanding and communication, and particularly between verbal description and visual representation. This has led to a particular way of parsing experience, and to several modes of entering and browsing the system. For instance, each case is accessible as a specific building, such as the Santa Clara County Hall of Justice, that can be explored much as an architect might browse a magazine article about the building, looking at a brief text description of the building, photos, and plans. However, each plan is annotated with "problematic situations" that are actually hypertext links into the discursive part of the program. By clicking on the button, the users reaches a "story" screen that lists the intentions of various stakeholders relevant to the problematic situation, a fuller text description of the general problematic situation with a diagram, text and diagram for a specific problematic situation as it operates in a specific building, several general design responses showing how one might respond to the problematic situations, and specific design responses from specific buildings. In addition, the user can browse the system by listing his or her interests and moving directly to stories about a given space type such as "courtroom" or issue such as "way finding." In addition, the designer can access brief synopses of key issues in a building type, for a space type, or for an issue. We are currently implementing the system on the Macintosh using Common Lisp and are focusing on libraries and courthouses as initial building types. Initial feedback from designers has been encouraging. We believe that this approach provides a useful alternative to design guidelines, that often tend to be too prescriptive, and the entirely inductive approach of many designers that may miss critical intentions.
