title	Possibilities of applying the E-government management concept in Serbian cities
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Recent urban transformations worldwide consequentially lead to the numerous environmental problems that have to be solved bycomplex structure of social interest groups which have to be included in that process. This demands initiated requisitioning andmodification of concepts and methodologies of planning and managing urban development. At this moment there are differentmodels used in world wide practice, but main bases of new methods and techniques are the same. Leaving the idea of possibility ofconstituting the universal urban planning model lead to very productive results in developing the disciplinary methodologies. Processof transformation of traditional comprehensive urban planning model to integrated procedural pluralistic model (based on sustainabledevelopment principles) is something that can be underlined as a main characteristic of disciplinary development. The questions ofdecision making mechanisms and plans implementation are put in axes of conceptual and methodological considerations. Urbanplanning loses the classic form of making the multi level comprehensive urban plans with exact spatial and time horizon. It means, ingeneral that planning and managing of urban development is aiming to be realistic, decentralized, strategic and problem oriented,arbitrary, not instructive, but understood as a efficient and effective process.Operational support to the this kind of approach are Decision Support IT tools, such as GIS - Geographical Information Systems orES -Expert Systems. Usability of IT tools is based on their capability to perform fast and complicated processing of spatial data andon their flexibility towards specific real problems which are to be solved. In order to use maximum of capabilities of these tools inpractice problem solving it is necessary to adjust their structure and usage to the: - actual conditions of socioeconomic of the contextin which urban development planning and management is performed, - practical demands that managing of urban development has tofore fill, - all participants in urban management process, - institutional mechanisms and procedures.

title	Realism vs. Reality in Digital Reconstruction of Cities
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The digital reconstruction of existing cities using virtual reality techniques is being increasingly used. For consultants, municipalities and planning departments these models provide decision support through visual simulations (El Araby, 2001). For academia they provide a new tool for teaching students urban design and planning (Okeil, 2001). For authorities they provide a tool for promoting the city on the world wide web trying to attract more businesses and tourists to it. The built environment is very rich in detail. It does not only consist of open spaces surrounded by abstract buildings but it also includes many smaller objects such as street furniture, traffic signs, street lights, different types of vegetation and shop signs for example. All surfaces in the built environment have unique properties describing color, texture and opacity. The built environmentis dynamic and our perception is affected by factors such as pedestrian movement, traffic, environmental factors such as wind, noise and shadows. The built environment is also shaped by the accumulation of changes caused by many influences through time. All these factors make the reconstruction of the built environment a very complex task. This paper tries to answer the question: how realistic the reconstructed models of urban areas can be. It sees “Realism“ as a variable floating between three types of realties. The reality of the physical environment which we are trying to represent. The reality of the digital environment which will host the digitally reconstructed city. And the reality of the working environment which deals with the problem of limitation of resources needed to digitally reconstruct the city. A case study of building a 3D computer model of an urban area in the United Arab Emirates demonstrates that new time-saving techniques for data acquisition can enhance realism by meetingbudget limitations and time limitations.

title	Information Spaces for Mobile City Access
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	This paper describes two complementary European research projects that share common interests and goals.The work described is intended to facilitate city analysis and support decision-making. The first project focuses on the distribution, access and ease of use of city data. The system allows access to historical data concerning key buildings in Liverpool, England, via a suite of web-based tools and a palmtop device. The second project looks at extending the functionality of traditional computer aided design (CAD) software to enable geometric and semantic data to be combined within a single environment. The system allows those involved in city planning to better understand the past and present development pattern of an area so that their decisions on future proposals are better informed.The paper concludes by describing a system that integrates particular aspects of the two projects, and the potential that this integration can bring.This new work provides mobile access to historical city development data, current city information and tools to support urban project development.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 43-47
summary	Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

summary	As a result of growing activity in the field of renovation and building within existing built contexts, modern digital tools and methods are increasingly in demand. Support of the planning process means: the step-by-step capture of building-relevant information, a rule and parameter-based development of solutions and the combination of traditional and automated methods and technologies used for model creation (building surveying) and model transformation (planning). This article discusses general requirements and the results from our own research and development as well as illustrating how building surveying can already contribute to the planning process more effectively using currently available tools.

title	Internet based support for architectural planning processes
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	As building projects become increasingly more complex, the number of project participants grows as does their spatial distribution. An effective decentralised work process and co-operation is of increasing importance. The global computer network, the internet, has great potential and recent times have seen the development of a variety of techniques in this field. The project described here is based upon this approach and also takes it a step further. A specific analysis of the topic and the subsequent identification of potential approaches formed the basis for an architectural application that brings the architect in contact with other project participants using the internet as a powerful yet simple and easy to use medium.

title	The (Non) Relation between Efficiency and Choice of Computer tools in Design Modeling: An Automated Protocol Analysis
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 567-574
doi	https://doi.org/10.52842/conf.ecaade.2003.567
summary	There exists a fundamental belief among mainstream CAAD software developers that a designer’s thought process is mainly driven towards achieving optimum efficiency. This paper argues that designers are not as much concerned with efficiency as much as protecting their personal preference for a certain method of object construction. Identifying and providing support to these methods - referred to here as ‘methods-ofmaking,’ is hence considered vital to how design efficiency is defined and how future CAAD tools are created. This hypothesis is empirically supported through a study conducted among 30 design students at the School of Architecture and Urban Planning, University of Wisconsin–Milwaukee.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	DESIGN AGENTS IN 3D VIRTUALWORLDS
source	IJCAI03 Workshop on Cognitive Modeling of Agents and Multi-Agent Interaction, R Sun (ed), IJCAI, Acapulco, pp 92-100.
summary	Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agent’s knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.

title	Are European cities becoming similar?
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The paper discusses city specific development patterns to overcome todays transport problems. The results are based on recent andongoing research activities at TUW-IVV and ITS. At previous CORP-conferences, we presented the basics and the development of aplanning support tool to find optimal policy packages in urban transport and land use (Emberger, 1998), (Pfaffenbichler, Emberger, 2001). The core of this planning support tool is a dynamic land use and transport interaction model. This model, which we refer to as Sketch Planning Model (SPM), is embedded into an appraisal and optimisation framework. The SPM and this framework were developed in the recently finished European Union funded research project PROSPECTS1. Case studies with this planning supporttool were performed within PROSPECTS for the cities Edinburgh, Helsinki, Madrid, Oslo, Stockholm and Vienna. These cities are principally comparable in regards of their status (capitals and major business and education centres), but different in their size, population density, transport system etc. A set of policy instruments like public transport improvements, car traffic restrictions, and infrastructure provision was available to formulate strategies to reduce negative impacts of transport and to increase welfare. The overall objective was a sustainable development of the city. Although the instruments and the goals are similar in all investigatedcites, different solutions were adequate. The solutions vary in regard of spatial implementation, implementation time and level of implementation. The paper will highlight some reasons for the different development paths of the cities. As well the comparison of the do nothing scenario as the comparison of the most feasible policy strategies shows that European cities are different, need different solutions for their problems and will stay different in the future.

title	Virtual environments in architecture and planning design: 4 possible approaches
source	International Journal of Design Computing
summary	Advancements in information retrieval (IR), local and wide area networks (LAN, WAN) and the Internet, human-computer interaction (HCI), and virtual reality (VR) technologies have enabled the emergence and availability of affordable real-time computer data visualisation and manipulation systems that can be deployed and interfaced to most Computer Aided Design (CAD) software systems. However, the rapid advancement and adoption of information visualisation in different areas is currently challenging VR system designers to formulate and deploy strategies and tools to effectively visualise, navigate and effectively communicate various types of information within a virtual environment (VE). A further problem relates to the fact that even within a single area or application the requirements are still diverse to the extent that different approaches and technologies still need to be employed before a satisfactory solution is reached. This paper presents four possible approaches in identifying and designing effective VR systems for architecture and planning design to allow the user to effectively communicate and share their experiences and ideas in a collaborative manner. It is also proposed that VEs should look beyond plain representations and reproductions of the real world environments that they portray and bear higher interpretation and expression values. The value of eliciting structuring and interfacing information and knowledge to a VE is also highlighted, as is the need for efficient database systems and CAD systems capable of exchanging information and data with VEs. Current efforts in prolonging the lifetime of VEs are being examined through four case studies that highlight the ever-escalating requirements that currently face VR researchers.

title	Supporting Communication Processes for Cooperative Planning and e-Government
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Abstract: As a reaction to societal, economic and technological changes, new forms of cooperation are applied in projects of urbanand regional development. We argue that this trend can significantly be amplified by the use of information and communicationtechnologies (ICT). Through ICT more persons can participate in a more focused, open, fairer and more transparent way. Complexinformation can be analyzed, the process is documented, reproducible and comparable. Methods and media can be combined in avery flexible way to design efficient and effective processes.To the extent that projects are stored in a knowledge base, knowledge management tools can exploit accumulating experience tocontinuously improve a methodology for cooperation in spatial development.With the introduction of ICT, existing cooperative methods in government and planning should not simply be copied to the newmedia without further modifications. Electronic techniques (synchronous or asynchronous, distributed or not, audio-, video or textbasedmedia) can be used for different traditional methods in different phases of the process, and they can be combined in completelynew ways, leading to new methods and workflows. Only if this potential of ICT is taken into account by restructuring the processitself, cooperative planning processes lead to informed high-quality decisions in less time.Our approach aims to explore the opportunities that new ICT offers for new cooperation methods in government and planning –beyond the extension of traditional methods to electronic communication media. It acknowledges the need for experimentation andan evaluation, not only concerning isolated methods but the combination of methods.

title	A NEW APPROACH TO THE INTERACTIVE RESOLUTION OF CONFIGURATION PROBLEMS IN VIRTUAL ENVIRONMENTS
source	3rd International Symposium on Smart Graphics, Heidelberg, Germany, 2-4, July 2003. http://www.smartgraphics.org/ . Proceedings published by Springer: Lectures notes in Artificial Intelligence.
summary	Intelligent Virtual Environments integrate AI techniques with 3D real-time environments. As such, they can support interactive problem solving, provided the underlying AI techniques can produce solutions within a time frame matching that of user interaction. In this paper, we describe an intelligent virtual environment based on Constraint Logic Programming (CLP), integrated in a real-time 3D graphic environment. We have developed an event-based ap-proach through which user interaction can be converted in real-time into appro-priate solver queries which are then translated back into automatic reconfigura-tions of the Virtual Environment (VE). Additionally, this framework supports the interactive exploration of the solution space in which alternative solutions (configurations) can be found. We demonstrate the system behaviour on a con-figuration example. This example illustrates how solutions can be interactively refined by the user through direct manipulation of objects in the VE and how the interactive search of alternative solutions in the VE is supported by these type of systems.

summary	In this paper we discuss designing abilities, such as creativity and learning, as abilities that emerge though interaction in cooperative human-machine networks. We concentrate in a design system that can exhibit and support creative behaviour using knowledge learnt through distributed human-machine interaction. In this context, conflict resolution and coordination is a main issue, as well as a main indicator for the creative and adaptive ability of the design system. More specifically, we are going to present a model of coordination developed using learning control and multi-agent systems methodologies and techniques. A prototype system is tested in a virtual collaborative design assignment for simple location and three-dimensional configuration problems.

title	A Preliminary Model of Community-based Integrated Information System for Urban Spatial Development
source	Proceeding of the 3rd China Urban Housing Conference, July 3-5 2003, Center for Housing Innovations, Chinese University of Hong Kong, ISBN 962-8272-26-8, pp. 417-424
summary	This paper describes a research on building Integrated Information System for Urban Spatial Development. The objective of the research phase discussed in this paper is to define a prototype of information system that basically facilitates information communication among involved participants in an urban spatial development planning. The system is designed by putting stress on local community. Their spatial perception and the availability of GIS technology in local context become constraints in building the system. Internet becomes the main alternative for information dissemination for this phase. This is also supported by the use of web-based GIS as framework of information system. Through few socialization sessions, the proposed model has indicated a prospected alternative to be seamless communication media among participants. To support an easy-access for local people in using this information system a mechanism of information access has been proposed in the form of local information center.

summary	We would like to present some recent work using cellular automata and agent modelling for the generative design of building configurations. The cellular automata is based on a 3d terrain model of a site (taken from the recent Europan competition) which is encoded with both topological and economic data, and agents that are light sensitive and which reconfigure the developing architecture by checking overshadowing and spatial occupation. The emergent pattern of development therefore results from an understanding of the programmatic and the spatial parameters of the task, and is intimately related to the site and its peculiarities.

summary	This paper describes work in progress on a collaborative project being undertaken by the Department of Art and Design at the University of Luton with the architecture and planning departments at Luton Borough Council and community participation. Focussing on the Plaiters Lea urban zone in Luton, the project uses a three-dimensional digital urban model of the townscape, as a collaborative design and communication tool for urban regeneration. The proposals being developed include elements of architectural and urban design, landscape design and public art. The philosophical motivation for the project is that of the community architecture and arts movements, in which a wide constituency of stakeholders is involved in the evolution of design proposals. The digital model is the key feature of a world-wide-web site that facilitates the exchange of design data between the participants. Digital modelling work has been used for undergraduate CAD skills development, and students are contributing design proposals as part of their studio work. Hence the project also has a pedagogic component.

title	Erfahrungen und Erfolge bei der Umsetzung von RAPIS - Raum- und Projektinformationssystem für die Vienna Region [Experience and Results with the RAPS-System for the Viennese Region]
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	In shortest terms: RAPIS is a metadatabase on spatial information in the “Vienna Region”. More interesting then this simple fact is the way how theproject was implemented and what the effects on regional development are.RAPIS is the acronym for “Regional Planning and Project Information System for the Vienna Region” and was implemented as the Austrian part of the Interreg IIc Project IM-PLAN (Implementation of models for co-operative planning in metropolitan regions). The aim was to create aninformation platform for planning relevant information for the whole region, integrating existing data sources from federal and state administrationas well as private companies. RAPIS enables an overview of the available spatial datasets in the "Vienna Region " and focuses on the following questions: Which datasets relevant for planning and development are available within the region? Who can use these datasets under which conditions? Which plans and projects do exist for the region? In addition also metainformation on the most important international data sources was collected as well as information to projects and plans with regional and trans-regional impacts. During the implementation great importance was given to communication and sensitisation for the importance the topic: geo-informationinfrastructre as a key ressource for spatial development and regional co-operation. It showed up that Austria and the "Vienna Region" have a very good initial position and excellent databases on national, state, local and international level. However, it seems that almost everything exists already but hardly anybody knows about it ... – potential users do not know what data and information already exists and how to get and use it. Intensive communication, information and permanent discussion of the topic „(Geo-) Information“ within the „planners community“ carried the topic into the public and strengthened the consciousness for the importance of information-infrastructure for regional co-operation.

title	On the Limitations of Shape Grammars: Comments on Aaron Fleisher’s Article “Grammatical Architecture?”
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 279-287
doi	https://doi.org/10.52842/conf.acadia.2003.279
summary	Shape grammars were introduced by Gips and Stiny in 1972. Since then, there have been many articles and books written by them and their associates. In 1992, Aaron Fleisher, a professor at the School of Planning, MIT, wrote a critique of their work in an article titled “Grammatical Architecture?” published in the journal Environment and Planning B. According to him, Gips, Stiny and later Mitchell, propose a hypothesis that states that shape grammars are presumed to represent knowledge of architectural form, that grammars are “formable,” and that there is a visual correspondence to verbal grammar. The strong version of “the hypothesis requires that an architectural form be equivalent to a grammar.” Fleisher considers these hypotheses unsustainable, and argues his case by analyzing the differences between language, and architecture, and by dealing with the concepts of lexicons, syntax and semantics. He concludes by stating that architectural design is negotiated in two modalities: the verbal and the visual, and that equivalences are not at issue; they do not exist. If there is such thing as a language for design, it would provide the means to maintain a discussion of the consequences in one mode, of the state and conditions of the other. Fleisher’s observations serve as the basis of this paper, a tribute to him, and also an opportunity to present an outline to an alternate approach or hypothesis to shape grammars, which is “nonlinguistic” but “generative,” in the sense that it uses production rules. A basic aspect of this hypothesis is that the only similarity between syntactic rules in language and some rules in architecture is that they are recursive.
