title Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

summary Development of net-based tools initiate a new architecture-computer science junction, offering a possibility to investigate distant exchange and updating of research work on architectural artefacts. Tools such as CAD platforms, rendering software and DBMS are integrated to the every day work of more and more architects and conservationists. Computer tools, which have been introduced in the process of analysing architecture as drawing and data management platforms, now bring to the fore a deeper change: distant analysis. The development of web technologies and the object oriented approach to knowledge representation give us an opportunity of research in the fields of collaborative work on architectural data models. The research presented in this paper focuses on a first set of network operative tools for a co-operation program aimed at developing web-enabled architectural data models referring to the evolution of Cracow's Old Town Hall.

title Conceptual Structural Design Through Knowledge Hierarchies
source Carnegie Mellon University, Department of Civil and Environmental Engineering, Pittsburgh
summary Computer support for conceptual design still lags behind software available for analysis and detailed design. The Software Environment to Support the Early Phases in Building Design (SEED) project has the goal of providing design generation and exploration capabilities to aid in the conceptual design of buildings, from architectural programming and layout to enclosure design and structural configuration. The current work presents a component of the efforts of the SEED-Config Structure group in providing computer support for conceptual structural design. The Building Entity and Technology (BENT) approach models data about building elements in a general, hierarchical form, where design evolution is represented by the growing specificity of the design description. Two methods of system-supported design generation are provided: case-based reasoning and application of knowledge rules. The knowledge rules, termed technologies, and how they are specified and used are the primary focus of this thesis. In the BENT approach, conceptual structural engineering knowledge is modularized into technology nodes arranged in a directed 'AND/OR' graph, where OR nodes represent alternative design decisions and AND nodes represent problem decomposition. In addition, nodes in the graph may also be specified as having AND/OR incoming arcs thus reducing the duplication of nodes and enhancing the representational power of the approach. In order to facilitate the incorporation of new knowledge into the system, and verify and/or change the knowledge already in the system, the data model and the interface allow for dynamic creation, browsing, and editing of technology nodes. Design generation through the use of the knowledge hierarchy involves the conditional application of nodes according to the design context as represented by the building element(s) under consideration. Each application of a technology node expands the design of building elements by increasing the detail of the design description or by decomposing the elements into less abstract components. In addition, support for simultaneous design of multiple elements and for iteration control are also provided. An important feature of the BENT approach is that the generative knowledge (i.e., the technology hierarchy) is detached from the information repository (i.e., the database of entities which make up the building). This allows the technology hierarchies to be used in a modular fashion from building problem to building problem.

title Situation Analysis of Design Tasks for CAD Systems
source Behaviour and Information Technology 1989 v.8 n.3 p.191-206
summary There has been little empirical research on the human aspects of CAD systems. In this paper observations on the analyses of designer activities are presented, by using a systems design approach. The paper concentrates on situation analysis and subsequent allocation of system tasks. A situation analysis was carried out in two design departments. The analysis consisted of a formal system description and a reconstruction interview. During the interview the previous week's activities were reconstructed with the help of photographs of the drawing board and protocols completed by design draughtspersons. This procedure was used for six design projects. In this study the technique of the reconstruction interview proved to be very useful and informative, and enabled three general conclusions to be made. First, designers liked the initial design phase and their responsibility for the final result. Second, they disliked the activities associated with drawing as well as the project documentation phase. Third, they preferred to work with two or more drawings on the drawing board. A number of frequent tasks could be identified, for example, large scale manipulation within and between drawings. In the final section, an example of a global allocation of system tasks for the design of a CAD system is given.

summary This paper is a contribution to the domain of computer tools for architectural and archeological restitution of ancient buildings. We describe an application of these tools to the modeling of the 14th century AD. Thermae of Constantin in Arles, south of France. It was a diploma project in School of Architecture of MarseilleLuminy, and took place in a context defined in the European ARELATE project. The general objective of this project is to emphasize the archeological and architectural heritage of the city of Arles; it aims, in particular, to equip the museum of ancient Arles with a computer tool enabling the storage and consultation of archaeological archives, the communication of information and exchange by specialized networks, and the creation of a virtual museum allowing a redescription of the monuments and a “virtual” visit of ancient Arles. Our approach involves a multidisciplinary approach, calling on architecture, archeology and computer science. The archeologist’s work is to collect information and interpret it; this is the starting point of the architect’s work who, using these elements, suggests an architectural reconstruction. This synthesis contains the functioning analysis of the structure and building. The potential provided by the computer as a tool (in this case, the POV-Ray software) with access to several three-dimensional visualizations, according to hypotheses formulated by the architect and archaeologists, necessitates the use of evolutive models which, thanks to the parametrization of dimensions of a building and its elements, can be adapted to all the changes desired by the architect. The specific contribution of POV-Ray in architectural reconstruction of thermae finds its expression in four forms of this modeling program, which correspond to the objectives set by the architect in agreement with archeologists: (a) The parametrization of dimensions, which contributes significantly in simplifying the reintervention process of the architectural data base; (b) Hierarchy and links between variables, allowing “grouped” modifications of modelized elements in order to preserve the consistency of the architectural building’s morphology; (c) The levels of modeling (with or without facing, for example), which admit of the exploration of all structural and architectural trails (relationship form/ function); and, (d) The “model-type,” facilitating the setting up of hypotheses by simple scaling and transformation of these models (e.g., roofing models) on an already modelled structure. The methodological validation of this modeling software’s particular use in architectural formulation of hypotheses shows that the software is the principal graphical medium of discussion between architect and archaeologist, thus confirming the hypotheses formulated at the beginning of this project.

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

title Planning building design by simulating information flow
source Automation in Construction 8 (2) (1998) pp. 149-163
summary Successful project management requires the effective control of the design teams and the exchange of information between them for successful design management. This paper describes a methodology involving discrete event simulation that can help the planning and control of building design. Discipline-based information flow models of the building design process are used to define the activities of the simulation model, concentrating on the concept and schematic design stages. Factors such as task durations and resources are then allocated along with any specific constraints that are to be evaluated. The model predicts the outcomes of the specific scenario of information related events, including design schedules and resource histograms. The paper describes the development and validation of the simulation model and discusses its potential application during the planning and design phases of building projects. It is concluded that this approach could form the basis of a useful tool for design managers responsible for multidisciplinary building design work.

summary Particular design approaches must be taught in order to take advantage of the strengths of computers in design rather than attempting to make computers conform to methods developed as by-products of manual design techniques. For the last three years our team of faculty teaching the second year design studio has been trying different approaches to the use of computers in design, in order to find the advantages and opportunities especially suited to electronic media. There are several projects during the semester which use computers at different stages of the design process. One of these projects, called “A Spatial Sequence,” uses information from a previous project as well as the knowledge from the computer class in parallel to design studio. The project asked students to create spatial archetypes based on the work of well-known architects. They explore the following topics as represented in the work of one particular architect: relationships of major spaces/minor spaces, approach/entry, and transition/threshold. Following the analysis, they create digital models to explore the spaces formed by their archetypes. Before committing to a physical study model, they look at the transitions between spaces by creating a sequence using the digital model and producing a series of shots through the digital model to show the flow of spaces. The use of computer through the process accelerates the options available to explore a sequence of elements, while simultaneously giving them a window to look into the spaces they have created. This hybridized approach of precedent analysis, digital modeling, and physical modeling was uniquely suited to the studio problem.

title A Mental Space Model
source Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 27-42
summary The architectural design process is often characterised a series of evolving ideas, and involving a cyclical process between design and visualisation. However, the nature of the internal representation still remains unclear. What is actually represented in a designers mental space and what drives and influences the mental design process? If we wish to programme a computer to mimic or work in tandem with the mental processes involved we need to make that representation and the associated cognitive processes explicit. The ways that designers form mental representations are so diverse, personal, and often transient that it is not easy to externalise and articulate them in explicit terms. In order to propose a mental model, we can take in a particular I psychological research approach; that of introspective observation from design drawing . In doing so, we posit an assumption that the designer's drawing can be seen as an extension of the internal mental feature, and hence internal representation could be inferred from the analysis of external representation - the drawing or sketch. This approach contrasts with the protocol analysis approach where mental operations are inferred from words, what could be termed thinking aloud.

title Playing with Design Intent: Integration of Physical and Urban Constraints in CAD

source Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 118-137
summary Our work deals with the exploration of a universe of forms that satisfy some design intents. That is, we substitute a “generate and test” approach for a declarative approach in which an object is created from its properties. In this paper we present an original method that takes into account design intents relative to sunlight, visibility and urban regulation. First of all we study how current CAD tools have considered these properties until now. Our conclusion is that the classical design / simulation / analysis process does not suit design practices, especially in the early stages. We think that an improved CAD system should offer the architect the option of manipulating abstract information such as design intents. We define an intent as a conceptual expression of constraints having an influence on the project. For instance, a visual intent will be stated with no reference to vision geometry: “ from this place, I want to see the front of the new building”. We show how to represent each of these constraints with a 3D volume associated to some characteristics. If some solutions exist, we are sure that they are included in these volumes. For physical phenomena we compute the volume geometry using the principles of inverse simulation. In the case of urban regulation we apply deduction rules. Design intents are solved by means of geometrical entities that represent openings or obstructions in the project. Computing constraint volumes is a way of guiding the architect in his exploration of solutions. Constraint volumes are new spaces that can restore the link between form and phenomenon in a CAD tool. Our approach offers the designer the possibility of manipulating design intents.

summary Unique to the interior design program at Cornell University is a planned pedagogical approach requiring equal emphasis toward manual and digital graphic communication at the freshman level. Prior to 1998, computer-based instruction only occurred at the junior year of study. Recognizing that cultural and symbolic biases against digital media were formally being instituted by curriculum policy, faculty searched for a new perspective. Central to success was the removal of illogically placed boundaries, both mental and physical. In response, students are now encouraged to cultivate a fluid dexterity between traditional and digital methods, at times using various skills concurrently for design analysis and representation (Figures 1, 2, 3, 4, 5, 6, 7). Course content for DEA115 ranges from basic orthographic drafting, paraline projection, and perspective drawing to color rendering and composition. Students utilize a full range of media: pencil, ink, marker, pastel, AutoCAD, 3DS/ MAX, and Photoshop in this graphics studio. Course meetings total six contact hours per week, constituting a three credit hour class. Assignments are purposefully created to shatter digital myths. For example, instead of a standard, rote drafting exercise, AutoCAD is used to explore design ideas through systemic object manipulation (Figures 8, 9).

source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary The evaluation of environmental aspects in architectural design has traditionally been performed by means of simple (and often simplistic) rule systems. These generally remain at the normative level of minimal control one encounters in building rules and regulations, thereby failing to provide sufficient information and clarity for design guidance. Despite this, evaluation results normally bound subsequent design decisions as fundamental, inflexible constraints. At much later design stages, whenarchitectural form has been largely crystallized and when environmental subsystems must be specified in detail, both the architect and the contributing engineers often realize the severe limitation of theinitial choices. A frequently voiced argument for such simplification in the guise of abstraction is the lack of detailed information on the form and functional content of a building in the early stages of the designprocess. This obviously presupposes a tabula rasa generative approach. The application of a priori knowledge in the form of types, cases, precedents and automated recognition permits direct transaction from the abstract to the specific at and between a number of predefined relevant abstraction levels in the representation. The combination of a priori knowledge at the typological level with multilevel representations permits the use of precise simulation techniques already in the early design stages and throughout thedesign process. The simulation results employ the dual representation principle of scientific visualization, thereby linking form with measurable performance. Feedback from the simulation provides the analysis and evaluation means for design guidance and for communication between thearchitect and the contributing engineers. A prerequisite to this is that the abstraction level in the representation constrains the analysis derived from the simulation, e.g., by means of grades of fuzziness applied to different zones in the representation on the basis of information specificity.

summary The Design Process - inherent conflicts? It is frequently stated that the activity of design is an iterative one; ie that it is a process whereby ideas are refined through constant change and development; if one also considers that designing is also very difficult: Hartwell and Holland (1) describe design "as an activity which attempts to reach an effective compromise between conflicting, complex and often apparently irreconcilable criteria"; then the key question arises: how can there be an effective interface between the obviously creative (generative?) elements of the design process and the (often) very functional / technical requirements of a typical design outcome.

summary Leeds Metropolitan University is well placed to carry out research into multi-disciplinary team-working, as all the design and construction disciplines are housed in one faculty. Staff have set up an experimental project, TIME IT (Team-working in Multi-disciplinary Environments using IT) which examines ways of working in the design/construction process and how IT is used when there is no commercial pressure. Four groups of four students, one graduate diploma architect, and one final year student from each of Civil Engineering, Construction Management and Quantity Surveying have been working on feasibility studies for projects that are based on completed schemes or have been devised by collaborators in the Construction Industry. Students have been asked to produce a PowerPoint presentation, in up to five working days, of a design scheme, with costs, structural analysis and construction programme. The students are not assessed on the quality of the product, but on their own ability to monitor the process and use of IT. Despite this, aggressive competition evolved between the teams to produce the 'best' design. Five projects were run in the 1998/99 session. A dedicated IT suite has been provided; each group of students had exclusive use of a machine. They were not told how to approach the projects nor when to use the available technology, but were asked to keep the use of paper to a minimum and to keep all their work on the server, so that it could be monitored externally. Not so. They plotted the AO drawings of an existing building that had been provided on the server. They like paper - they can scribble on it, fold it, tear it and throw it at one another.

summary Design studio still plays a very important role in architectural design education today since teachers and students can exchange their thinking directly. In the whole teaching/learning process, there are a lot of information to be exchanged between the teachers and the students. How to organize the information and record the whole teaching/learning process is very interesting to us. The increasing use of CAD raises some problems with its advantages when the amount of compute-files becomes very big and they are in different formats. In the third year design studio teaching in the academic year 1998/99 at Department of Architecture in Southeast University, we try to use WWW techniques and features to organise the design information. We try to integrate the teaching programme, the project information, the reference material and the students' work together, to record and monitor the teaching process. Since the teaching programme is clearly organised, we could use some strategies and ideas to control the organisation of file storage and presentation. It creates the basis for the further development of applying network to aid the studio teaching.

summary In this paper, the integration of modelling the changes in land-use and the changes in the infrastructure network will be described. Emphasis is laid on the automatic development of the network instead of changing the network by hand before simulating the changes in the land-use pattern.The approach and working procedure were tested by developing a pilot model simulating the spatial situation on the Frisian island Ameland (The Netherlands). The pilot is developed within the geographical information system Arcinfo. In this pilot model, special attention is paid to the extension of the infrastructure network and the allocation of more than one activity. Network analysis for the purpose of network extension is based on graph theory. Selection of links is based on the increase of the total accessibility within the network system as a result of adding a link to the network. The allocation of activities is based on several selection criteria and takes place within a cellular grid. Several methods ofselecting cells and links and the choices made will be discussed.

title Ancient structures and modern analysis: investigating damage and reconstruction at Pompeii
source Automation in Construction 8 (1) (1998) pp. 125-137
summary The paper describes the application of non-linear structural analysis methods to address archaeological questions concerning the reconstruction of the ancient city of Pompeii after a major earthquake that occurred 17 yr prior to the famous eruption of Mt. Vesuvius in 79 AD. It presents preliminary findings in an effort to develop an approach to modelling the two-way out-of-plane behavior of unreinforced masonry walls, including comparison studies with published analytic and experimental results for one-way loaded walls, plus a trial analysis for a two-way span condition. The approach requires the application of computationally intensive non-linear analysis techniques, since the linear analysis methods used in conventional design and education are inadequate to model the behavior of unreinforced masonry. Developing an understanding of the two-way behavior of unreinforced masonry has implications not only for archaeological investigation of ancient structures, but also for modern renovation of historic structures.

summary As computer technology is integrated into design curricula, significant shifts in pedagogy must be developed that acknowledge and incorporate alterations in teaching design process. This paper offers a critical analysis of the effects on design productivity of an experimental design studio that proposed and investigated an interdependent relationship of mechanical and digital technologies. A design studio was developed based on linking digital and physical technologies through systematic transformations of one technology into the other. Transformations were structured as a series of projects to test concepts of "making/building" in the form of abstracting/ making concrete, building/un-building, and un-making/making. Student permutations of the transforming operations revealed that design processes occurred as a mutuality, rather than an opposition, of the virtual and material. Design activity was revealed as a patterned flow of systematic formulations built on previous transformations. Key results of the studio indicated increased early development of conceptualization, increased refinement and integration of design issues throughout the project stages, and greater sensitivity to use of materials in a more holistic realization of concepts. Current curriculum structures that fragment technologies and subjugate ideas of craft, technology, and ideation into separate courses or educational issues, do so at the expense of substantive design refinement. The experimental studio of interdependent technologies offers digital and mechanical technologies as an holistic feature of design processes, thus indicating a greater integration of "support" courses into design studio and implicating an increased role of "hands-on constructing" such as that in wood/metal shops.

summary Recent advances in computer graphics and 3D user interfaces have enabled the emergence of 3D sketch modeling as a viable approach to architectural design, especially in the early schematic phase. This paper describes how a system can be built and used which integrates the capabilities of a good structural analysis system in the user-friendly working environment of a design-oriented modeling program. The structure of a building model as seen by finite element algorithms is a schematic idealization of the building's physical structure into nodes, elements, internal releases, boundary conditions, and loads. The more familiar architectural model used for design visualization represents spatial elements such as roofs, floors, walls, and windows. Rather than treat these models independently, the structural model can be defined in relation to the architectural as a virtual model with inherited common characteristics and additional relational and attribute information, using feature-based geometry data structures to organize topological intelligence in the spatial model. This provides the basis for synchronous modification of structural and architectural aspects of the design.
