title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

summary The product of the Urban Design process in the public sector in the UK is usually a briefing document of some kind which communicates design ideas in outline both to the lay public and to private developers. The problem with briefing effectively is that outline expression of ideas does not provide a strong basis for negotiation with developers; the temptation therefore is to work up one proposal in detail and to present it as the only option. This type of prescriptive briefing may be successful in situations where the public body has control over the land, the economy is buoyant and the site has a simple context. Its problems are that it is labour intensive, so some areas are covered in detail, others not at all; it is seen as restrictive by developers, so may create a climate of conflict rather than certainty; it is not responsive to change; it covers specific sites thoroughly but does not deal well with large, complex areas; on large sites it tends towards a homogeneous environment whereas the nature of towns and cities is pluralistic and heterogeneous; it confines the Urban Designer to site specific work rather than allowing concentration on the whole urban system. Urban Designers at the London Docklands Development Corporation felt that CAD might present some answers to these problems in facilitating an iterative, interactive briefing process which could respond quickly to change; whereby varying options for development could be investigated fully but quickly and resource-efficiently; which could be used to communicate design ideas effectively to non-professionals; which could help to make negotiation with developers more effective, less confrontational; which could deal with large, complex sites effectively. The idea was that a piece of city could be modeled on the computer and an urban design study would then be carried out on it which would test varying options for development, resulting in an outline, but three dimensional, model for an area which could be used in three ways: as a briefing tool, as part of a marketing exercise and as a tool to aid effective negotiation and consultation at the planning stage. A pilot project was carried out on a set of development sites at East India Dock and, following the success of this, a full study was carried at Surrey Quays Centre. The paper describes these projects and discusses both their products and their effect on the developmentprocess as aids in decision making.

summary Solidere, a Lebanese joint-stock company, was created by government decree in 1994 to reconstruct Beirut city-centre. The company, a form of public-private partnership, has a majority share holding of former owners and tenants of city-centre property. Several projects are underway, including the redevelopment of Place des Martyrs, once the bustling heart of Beirut but badly damaged during the war. Urban planners in Beirut have recently developed a 3D computer model to visually describe the spatial characteristics of Martyr’s Square and its context, prior to inviting design proposals for an international competition. This paper describes issues pertaining to the development of the model to meet the needs of urban designers and town planners. It also considers potential future uses of the simulation, outlining areas for further research and development.

title Built form and urban configuration development simulation
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 The "centrality/potential" model, proposed by Krafta (1994), for configurational development, aims at the simulation of inner city built form growth. This is generally achieved by simulating the uneven distribution of floor area increments, resulting from replacement of old buildings, considered "devalued capital" form new ones. The model considers two main variables - public urban space system and built form - and treats them unevenly; the former is extensively disaggregated whereas the latter is not. This feature enables the model to make just a rough account of intra-urban built form development. The issue of built form simulation is then taken further in the following way: a) Urban built form is disaggregated by types. Buildings are classified by a cross combination of scale, purpose, age and quality standard; b) The city is itself considered as a set of intertwined typologic cities. This means that each unit of public space is identified by its dominant built form type, producing a multilayered-discontinuous city. Each one has its own market characteristics: rentability, technological availability and demand size; c) The market constraints determine which layer-city has priority over the others, as well as each one's size of growth. References to rentability and demand size gives each built form type priorities for development d) Spatial conditions, in the form of particular evaluation of centrality and spatial opportunity measures, regulates the distribution of built form increments and typological succession. Locational values, denoted by centrality and spatial opportunity measures, area differently accounted for in each layer-city simulation. e) Simulation is obtained by "running" the model recursively. Each built form type is simulated separately and in hyerarquical order, so that priority and replacement of built form types is acknowledged properly.

title A Tool for Conceptual Design Evaluation Based on Compliance with Supplementary Planning Guidance and Local Planning Policies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are being designed in order to check design compliance with the requirements of local planning authorities; with regards to building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. The measures to determine proper evaluation will be based upon site-development briefs, and design guides produced by the local planning authorities. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. It will also provide many functions for editing two and three dimensional drawings specifically for the environmental analysis tasks. In addition to the common graphical output of Aut0CAD; i.e. plans, elevations and three dimensional models, the tool will generate textual analysis of the design in report format to use as part of the Environmental Impact Statement of proposed development. The speculative tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out tailor-made for architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of materials for environmental statements. Second, field observation will be carried out to observe the concerned professionals as decision-makers while assessing building design proposals. A prototype will be designed and then tested against the expectations of the tool designer, then the tool performance will be evaluated by a team of professionals participated in the field studies. A critical analysis of the prototype design methodology and the concluding study findings will be documented as part of a postgraduate research thesis to be completed in June 1995.

summary The Venice has been in the middle of a lot of proposals and initiatives for some time that range from environmental restoration to the transformation of important areas of the ancient centre, from the renewal of the exibition spaces to the rationalisation of manufacturing areas and communications. Opinions as to how, where and whether to go ahead with these interventions are controversal and and they has been responsable for the current situation of status quo in Venice. Various proposals have been put foreword to semplify city control regulations to put into actions quickly and efficiently in the complicated context. Such methods supported by multimedia tools can efford the participation of the actors and the decision making. Application the Strategic Choice approach for the curring out of the projects proposed for the metropolitan area of Venice and the use of multimedia tools (visualisation and hypertext) to favour the involvement of the actors are described.

summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

title A Decision Support System for Architects in the Rural Housing Situation in India
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Even a conservative estimate of the rural housing shortfall in India, is 20.6 million houses. There are three contexts under which external intervention is necessary, the endemic low housing qualityof the poor and landless, the major development projects where displaced people have to be rehoused, and rehabilitation of victims of natural disasters such as the periodic floods or unprecedented earthquakes like the recent one in Maharashtra, Central India, where we successfully applied this method. Interventions by government agencies or charity organisations, have often failed to achieve a viable sustainable habitat, primarily because of misplaced perceptions in need assessment, resulting in disrupted societies. Tailored to the Indian rural housing scenario, the study developed a participatory interface to aid architects and planners in information gathering and systematization of need assessment for input into the designing and decision-making process. The method based on field tested participatory information collection games consists of threemajor stages. The first stage involves user-interactive documentation of the baseline data. The second, involves participatory group analysis and evaluation of issues coupled with rapid interactive verification of information collected in terms ofspatial organisations and production mechanisms. The third is a tool for rapid systematised retrieval of information, for synthesis into preparation of an "user needs statement".

summary This project was an investigation into the application of Urban Information Systems [UIS] based on 3-Dimensional computer models. The research centred on a collaboration between the Architecture and Buildings Aids Computer Unit, Strathclyde [ABACUS] and the Edinburgh Old Town Renewal Trust [EOTRT] to develop a detailed computer model of Edinburgh's old town. The area of particular interest is the development of an interface to a database of property related information. This provides a means of analysing the multi-layered and multi-dimensional spatial data which is characteristic of urban environments. The research also investigated how, by using multi media technology as a data integration tool , urban models could be used to improve decision making in the framework of urban management.

title Contributions of a Complex Object Retrieval Model to a Dynamical Architectural Design Process
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary When a new Architectural Construction Project starts, all the steps of the technical design are completely redefined. The experience gained in old projects is not easily reusable. Only personal experience of each project member is relevant. The global experience of a project is difficult to manage and to define. The designers of new project have many things to learn from previous experiences that may or not be good. The use of experiences may avoid either looking for asolution to previously resolved problems or making the same mistakes. To realise experience reuse during an architectural technical design we proposed to combine two actual research works:(i) a Dynamical Architectural Construction Process (DACP), (ii) a Complex Object Management System (COMS). The first work puts forward an original construction process based on a model that uses a geometrical definition of an architectural object to produce the constructive definition of this same object. The original features of this model are: (i) the insertion of a logic level between the volume level of an architectural object and its element level, (ii) dynamic management of the different representations of an architectural object during its technical life cycle. The COMS capabilities concern memorisation and retrieval of complex objects. The use of classicalData Management Systems to store these objects is either impossible or unusable due to data dispersion. In our approach, an architectural experience is viewed as an complex object. The COMS manages an Object Base which contains different Architectural Construction Experiences in previous projects forms. At any time during the DACP, the designer can asked the COMS to retrieve a part or a whole of a previous project that illustrates its current technical state. Thearticle presents two research projects and a study of the contribution of experience reuse in a construction process.

title Architectural Photogrammetry & Knowledge-Base Systems Record & Redevelopment
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In redevelopment projects, the purpose of heritage recording is part of an investigative process to achieve understanding about structures so that designers can make the appropriate design decisions. It is desirable to integrate the knowledge of the recording and documentation specialist, who has first-hand knowledge of the building, with the interpretative process of evaluating the building information and making design decisions. New developments in the fields of photogram-metric recording and computer science has led to improved "image understanding". This paper describes research that is the result of exploring the concept of integrating new digital photogram-metric recording processes with an automated expert evaluation tool. The goal of this research is to expedite the acquisition of heritage building information for use by a knowledge-based system capable of providing the designer with building performance evaluations. Photogrammetry records all data as a series of three-dimensional coordinates which make it a natural partner for today's three-dimensional CAD systems. Generating a three-dimensional model of architecturally significant physical forms and details can provide a basis for evaluation, understanding, education, and design. The purpose of knowledge-based systems in construction is to enhance the decision-making process with specialized knowledge and experience. The linkage of CAD databases with knowledge-based systems provides a source of input data, such as a three-dimensional model, significant to a particular problem. This research is a collaborative effort between two groups, the Swiss Federal Institute of Technology in Zurich Switzerland, and the University of Manitoba in Winnipeg, Canada.

title Post Occupancy Evaluation as a Strategy to Develop an Improved Work Environment
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary A post-occupancy evaluation is a formal way of finding out whether a recently occupied, remodelled, or built environment is performing, as was intended in its programming or design, and a term which has been developed in the professional field in the United States over the last 20 years. The Scandinavian approach to the same question has emphasised surfacing the values of the users of the work environment as a tool for a more comprehensive approach to space planning and design. A recent case-study of the Taubman Building at Harvard University's John F. Kennedy School of Government was aimed at blending the two strategies for evaluation, defined postoccupancy evaluation as a dialogue with the client, as a process to help the client reflect on spatial and technological improvements, or alternate strategies for organisational locations in buildings, and offers an interesting example of a possible future direction for POE's. Sheila Sheridan, Director of Facilities and Services at the Kennedy School, commissioned the case-study, and has been using it result in her daily work. Jacqueline Vischer, who has developed a survey of seven key dimensions of work-place comfort for commercial office buildings throughout eastern North America, and Turid Horgen, who has developed tools for participatory environmental evaluation and programming, widely used in Scandinavia, carried out the study and facilitated the evaluation process. The study is also done in the context of the ongoing research on these issues in the design Inquiry Group at the School of Architecture and Planning at MIT, which is involved in a larger program for developing strategies and tools for more effective programming and management of corporate space. This research defines the workplace environment as the interaction between four dimensions: space, technology, organisation and finance. Our approach is to integrate programming and evaluation with organisational planning and organisational transformation.Post occupancy evaluation is seen as a way to inform the client about his organisational culture as he manages the fit between a facility and its uses, and as one of several tools to bridge the frameworks and viewpoints and the many "languages" which are brought into the decision making process of designing the built environment.

title Data representations in an integrated architectural design environment
source University of Strathclyde, Dept. of Architecture and Building Science
summary The architectural design process is very complex and involves cross-disciplinary communication among many related fields. Given the further problems arising from the technological advances in building materials and construction methods, an integrated design environment becomes a central design issue. There have been many attempts to analyse and structure the design process as a uniform hierarchical framework. Most of the attempts resulted in a vague and inappropriate outcome due to the lack of understanding of architectural design complexity and inconsistent design data control sequence. A design problem cannot be comprehensively stated because the design problem has a multi-disciplinary nature and the design problem itself evolves as solutions are attempted by the designer. Therefore, an ideal CAAD system should have the capability to accommodate the multi-disciplinary nature of design and should not prescribe or restrict design concepts and design knowledge. A well designed integrated design environment provides more information and invokes creative imagination for each design stage, and therefore creative decision making by the designer can be achieved. This thesis proposes a prototype architectural design environment, Hybrid Integrated Design Environment [HIDE], which aims to integrate all applications for designing a building. Within the object-oriented design environment, a unified data model and a data management system have been implemented to seamlessly connect all applications. Development of the environment needs to consider the fundamental interaction between each module. Devising a data structure that is appropriate to an effective data communication among the various design stages is essential in a totally integrated CAAD system. The suggested unified data model organizes the structure of the design data to keep the design consistent throughout the design and construction process. By means of the unified data model, integrated CAAD systems could represent and exchange design information at a semantic level, i.e. the user’s way of thinking, such as exchanging components and features of a building rather than graphical primitives. In consequence, the unified data model reduces the misunderstandings and communication problems among the multiple disciplines of architectural design. The suggested data management system supports the consistent and straight forward mechanisms for controlling the data representation through the inter-connected modules. It is responsible for creating, maintaining, and viewing a consistent database of the design description. It also helps to perform effective data communication among the various design stages to ensure quality and time saving in the final construction of the building. To support inter-disciplinary communication of design concepts and decisions, the integrating of relevant CAAD tools is essential. In the environment, the integration of CAAD tools has been performed on the basis of how well computerized design tools can assist designers to develop better solutions, enabling them to manipulate and appraise varying solutions quickly and with a minimum of effort in an environment conducive to creative design. A well designed user interface system can also benefit the seamless working environment. The proposed user friendly interface system allows a user to explore the environment in a highly interactive manner. From the development of the early data model to the final design, a user could benefit from the prototypes and methods of the user interface system. The ultimate goal of the prototype environment is to suggest a future design environment which helps the architect to have minimum discontinuity in his creativity and make the design process similar to the natural design process with the help of a set of design assistance modules. A prototype version of HIDE has been implemented and a demonstration of the environment is part of this thesis.

title Form and Performance in Intelligent CAAD Systems for Early Stages in Solar Design Building
source Technion, Faculty of Architecture and Town Planing, Haifa
summary Great care should be taken at the initial design stages to determine the principles and solution schemes for climate and energy-conscious buildings. The present study deals with supporting the designer's efforts at the early stages to lay down the appropriate principles for a conceptual and geometric design of energy-preserving buildings, which are also thermally comfortable and adapted to local climatic conditions. For years, especially during the last decade, important data concerning climate-conscious construction has been compiled, but the information has not been utilized by designers, due to its inaccessibility. It is significant, though, that solutions based on this knowledge could be found and assessed at the preliminary design steps. A correct climate-conscious design conceived at the initial stages may guarantee that during later phases of the project's development no problems calling for essential and drastic changes in the basic design will crop up. The meaning of such changes at later stages may require sometimes a redesigning of the entire project. It is vital, therefore, to understand at the pre-conceptual phase, what are the correct climatic-solar design strategies which satisfy the requirements of the local conditions, and enable the attainment of thermal comfort conditions, while consuming the least possible energy. The present study proposes a computer-aided passive solar design system (PASYS) which enables the handling of entire designing process, and its general, conceptual aspects, as well as the preliminary designing steps and their particular, practical aspects. The system is based both on a knowledge base which stores the existing information concerning solar-climatic construction in the form of rules of thumb, and on precise procedural models which enable finding solutions suited to the local climatic conditions. The proposed system is an intelligent CAAD system which equips the designer who is aware of the constraints of climate and energy, with a tool to achieve a better design. PASYS was developed as a universal system to deal with the various activities involved in the initial – pre-conceptual and conceptual - design stages. The system supports the following design activities of each stage of this kind: analysis, synthesis, documentation, assessment and decision making. It is capable of analyzing given conditions, thus helping the designer understand which are the significant preliminary design stages that have a bearing on thermal comfort conditions in a given climate. The system is also capable of proposing solutions corresponding with the particular design phase, and assess their adequacy. These solutions take into account the constraints determined both by the designer and by the system itself, owing to the knowledge base it contains. The system can also document the various solutions that have been found and selected, so that may be further developed at later stages. This documentation is carried out by a graphic interface, developed as part of the system, as well as by an interface devised for existing CAD software. This study highlights the interaction between form and performance. The system is able to assess the performance of a proposed design by considering a given geometry (form), or viceversa, it is able to recommend a solution that can deliver desired and required performances. The study comprises three parts: (a.) Development of the conceptual model of a knowledge based design process. (b.) Further development of the initial stages of the afore mentioned process, including the pre-conceptual and conceptual stages. (c.) Demonstration of the mode of work with the PASYS system. // The first part of the study deals with the definition of the design process, the definition of the various design steps and their characteristics, and the definition of the activities involved in each design step. This part of the work also presents the kinds of knowledge bases affecting the design process, and shows how this knowledge is an inseparable part of the design process. The second part deals with the development of the initial design stages - the pre-conceptual and the conceptual - which are based on knowledge. This part also contains compiled knowledge that is relevant to the design stage, and a knowledge storage and retrieval method that was developed so as to make the knowledge available and accessible on demand. This part further presents precise procedural methods, developed to find solutions adapted to the specific given conditions, and to precisely assess the performance of the proposed solution. A case in point is the module of the SHADING system which enables a precise assessment of the mutual shading of buildings, and an examination of the exposure of the southern elevation to the sun, which is necessary in order to determine the effective solar absorption area in a proposed project in given environment conditions. The third part of the study demonstrates the solar-climatic design process put into action and supported by the system that was developed. This system enables the designer, even at the preliminary design stages, to determine which properties relating to local climatic conditions he will introduce into the building. This important, seemingly natural act, is usually performed during more advanced stages, when it might generate significant changes in the design, at a juncture when changes are hard to make. A PASYS-aided design environment ensures that from the beginning of the designing process, the project will be designed correctly and efficiently as far as energy is concerned.

title Strategic Urban Planning in the Netherlands
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Since the mid-1980s, several Dutch towns have initiated many urban planning and design activities for their existing area. This represented a shift in that previous urban planning projects typicallyconcerned expansion in the outskirts of the city, or urban renewal. The complex and expensive renovation of the existing housing stock rarely allowed a deep interest in urban design. Since 1985, attention shifted from the housing stock to the city as a whole. Furthermore, public andprivate actors increasingly become involved in the planning process. It became clear that a more comprehensive plan for the whole existing town or region was needed. Conventional planning instruments were considered ill-suited for this new challenge. The paper discusses promising attempts of various urban planning instruments to get a stronger but also more flexible hold on thetransformation of the urban planning area in the Netherlands. These new planning instruments have three common characteristics: (i) they give special attention to the different levels of urban management needed for different urban areas, (ii) these strategic plans provide an integral view on the urban developments, and (iii) these plans introduce a new strategy to deal with both private initiatives to transform urban sites and monitor wishes, proposals, etc. from inhabitants in the neighbourhoods. A comparative analyses of several cities indicates, however, that, in addition to these common characteristics, major differences between their strategic plans exist depending upon their historic patrimonium, economic status and planning tradition.

summary This paper will present a project, which was first initiated in 1994 as a graduate students seminar and is now being continued as a research project in a cooperation of computer scientists, architects and archaeologists. An ancient roman city (Colonia Ulpia Traiana near todays Xanten in Germany) has been reconstructed, using various levels of abstraction. On the coarsest level, a 3D-model of the whole city was established, distinguishing between different historical periods of the city. The second level picks places of special interest (temples, the forum, the amphitheater, the townbaths etc.) and reconstructs these buildings or groups of buildings. On the finest level important interior parts or functional details like the Hypocaustae in the town-baths are modelled. All reconstructions are oriented as close as possible to results from excavations or other available documents. All levels of the 3D-model have been visualized using photorealistic images and sequences of video animations. The 3D model is integrated into a multimedia environment, augmenting the visualization elements with plans of the city and individual buildings and with text documents. It is intended, that parts of the outlined system will be available at the site of the ancient city, where today a large public archaeological park is located.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs

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 The construction delivery system of the information age
source Automation in Construction 8 (4) (1999) pp. 417-425
summary The Performance Based Studies Research Group (PBSRG) at the Del E. Webb School of Construction, has developed a methodology to process data into information to reduce facility system life-cycle cost and risk of nonperformance. The methodology reshapes the current construction industry model from a `low-bid', `all the same' industry into a `value added' performance based industry. The performance information regulated industry changes roles, partnerships, and communication methods between the construction industry and facility owners. The PBSRG research effort (US$1000K, 1994–present) includes the design and improvement of the Performance Based Procurement System (PBPS), performance data collection on general, mechanical, electrical, landscaping and janitorial services, and design services in the public and private commercial sectors, the identification of performance levels in the industrial sector, and the design of a performance based structure for a manufacturer of construction systems, as well as the education of the facility owners and the construction industry.
