title	Dynamical structural modeling A collaborative design exploration
source	International Journal of Architectural Computing vol. 3 - no. 1, 27-42
summary	This study is based on a generative performative modeling approach that engages architects and structural engineers in close dialogue. We focus on knowledge shared between engineers and architects to apply the Finite Element Analysis based structural design technique Evolutionary Structural Optimization [ESO] as a way to understand or corroborate the performance factors that are significant in determining architectural form. ESO is very close conceptually to the dynamical system of matter and forces of growth itself. It has parallels both mathematical and metaphorical with natural evolution and morphogenesis so it has been poignant to apply the approach to a formal architectural case study in which the generative influence of these processes is inherent.

title	Design Innovation through Constraint Modeling
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 671-678

summary	This paper describes how constraint modeling can support design innovation. Furthermore, it lays out how constraints are employed in the construction and exploration of a model’s design space. The paper places this approach within the larger context of design exploration using computational and conceptual representations of design. Four general constraint types are identified and examples from several workshops and design studios are presented for each of the constraint types. The examples range from product design to structural design to fabrication issues in architecture. Based on a review of the literature the most common constraints are of geometric, topologic, functional, and quantitative type. Based on the case studies the paper describes how the different types of constraints can be used as design drivers and help in the exploration of solution space. In conclusion the paper identifies the addition of bi-directional properties to constraint modeling as the next challenge in improving the application of constraint modeling in design exploration. Furthermore, the paper demonstrates the necessity to develop better constraint models for cross domain design.

title	Analysis of the possibilities offered by the application of parametric modeling technologies in the design processes shared between architects and industrial designers: The prefabricated house case.
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 300-303
summary	Traditionally, the teaching of digital design systems has been focused on the operative learning of software. However, this almost exclusively technical approach has leaded to a partial view of these systems, as well suited platforms to exploration of project’s possibilities. Consequently their relevance as a base for project representation and therefore as a useful instrument for conceptual exploration for design and experimental research of their processes have been undervalued. On the other hand, this restrictive perspective results in an important waste of the teaching possibilities lying in CAD software related with interdisciplinary teamwork. The following academic experience obeys to a new insight of how to teach these tools, based upon problem solving in Design by interdisciplinary students work teams from Architecture and Industrial Design. In this bet, the learning process is flexible, shared and collaborative, according to the requirements of each project, powered by the commitment of facing common goals. [Full paper in Spanish]

summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wireframes, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

title	Design Using Evolutionary Optimisation and Associative Geometry
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 243-254
summary	This paper describes the usage of parametric design and evolutionary optimisation techniques in architect-engineer collaborations. It discusses the apparent challenges in setting up a trans-disciplinary working-platform that cuts across profession-specific boundaries and negotiates between the otherwise distinct work-methodologies through the use of intelligent CAAD applications. Two approaches to architectural form finding have been combined in this research. The first, parametric design, uses a proprietary package as a key element to the organisation and reorganisation of architectural design. By doing so, it is providing it with intrinsic flexibility allowing designers to go beyond form and accommodate performance data for versioning. The second, ESO (Evolutionary Structural Optimisation), is an engineering tool based on the use of finite element analysis (FEA) capable of optimising the formal geometry of an object to obtain minimum volume under even stress-distribution through an iterative design process. In undertaking this research it became apparent that different levels of resolution need to be addressed in the form-finding process in order to investigate the full potential of the interactive use of parametric design and evolutionary optimisation. The case studies reflect this diversity and demonstrate more successes, limitations and future challenges within the transdisciplinary, collaborative effort.

title	Interdisciplinary Knowledge Modelling for Free-Form Design – An Educational Experiment
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 465-474
summary	The recent advances in digital design media and digital fabrication processes have introduced formal and procedural effects on the conception and production of architecture. In order to bridge the individual concepts and processes of multiple design disciplines, intensive cross-disciplinary communication and information exchange starting from the very early stages of design is necessary. A web-based database for design learning and design teaching named BLIP is introduced. In this framework, cross-disciplinary domain knowledge becomes explicit to be taught and transferred in Free-Form Design research and education. BLIP proposes a conceptual map through which the user can construct structured representations of concepts and their relationships. These concepts are high-level abstractions of formal, structural and production related concepts in Free-Form design development. BLIP is used for formalizing, organizing and representing conceptual maps of the three domains and facilitates information and knowledge sharing in collaborative conceptual design in context. The paper introduces the application together with its application in two educational design experiments.

summary	The notions of collaborative exchanges, leadership, and entrepreneurialism that cross disciplinary boundaries were promoted in a digital design-build studio taught in spring 2005. With the starting funds of one dollar, the studio took up the challenge of building two full-scale tensile fabric structures that mark the entrances to a downtown San Antonio building. Structures of 1200 square feet total surface area were successfully designed, engineered, and executed within a semester framework at a final cost of $102,490. Collaborations were fostered with 24 industry partners from Asia, Europe, Australia, and USA, including four structural engineers. Innovative pedagogical, collaborative and project management methods were employed. The studio was structured as a self-organized design “firm.” Positions were created and students were “hired” into the firm to play different roles. The studio utilized web-based communication and project management tools. After a four-week warm-up project that established an innovative studio culture, professional schedules were prepared and the engineers were engaged in the collaborative process of designing the anchors, cables, connections and PTFE/PVC membranes. The peculiarities of digitally designing, fabricating and erecting tensile fabric structures were comprehensively explored. The studio completed all the CNC fabrication, concrete footings and membrane fabrication at local workshops through special partnerships.

summary	This paper presents an experience of collective digital fabrication and parametric modeling of furniture made with recycled plastic waste, inspired by natural elements of the Brazilian northeast. In addition to conventional joinery techniques, we highlight the technologies of rapid prototyping (PR) and digital fabrication (FD) (Volpato, 2007, Pupo, 2008; Pupo, 2009); as tools that promote a paradigm shift, both in the design process and in production and materialization (Kolarevic, 2005), allowing recycled plastic to have new applications. We started with a brief review of digital fabrication processes in Brazil, emphasizing collaboration in design and execution. Then, we contain the recycling of plastic and the need for actions for its best destination. Finally, we present a sustainable and collaborative design experience: the modeling and digital fabrication of furniture, entirely produced from recycled plastic, called “Banco Cabaça”.

title	Digital Design: The Quest for New Paradigms
source	23nd eCAADe Conference Proceedings [ISBN 0-9541183-3-2], Lisbon (Portugal) 21-24 September 2005, 880 p.

summary	As the field of computer-aided design evolved over the last thirty years or so, it has witnessed five changes of emphasis in research direction. In the first stage, the use of computers in architecture focused on the development of Computer Aided Design (CAD), that is, systems that simulated the use of drafting tools, and research was mainly concerned with the satisfaction of designers' ergonomic needs. In the second stage, there were efforts to use computer tools in non-graphical aspects of designing, such as the use of Data Base Management Systems (DBMS) in the quantity survey of buildings. The concern was to satisfy the cognitive needs of designers by focusing on the way information and knowledge were perceived, acquired, stored, and processed. In the third stage, the focus shifted to the development of realistic models of buildings to permit the assessment of design proposals. In the fourth stage, the focus was on studies concerned with the encoding of architectural knowledge into design tools (KBMS), and the discussion was whether to go towards design automation or design supporting tools. In the fifth stage, with the advent of the Internet and the development of communication tools, research became focused on the collaborative and social aspects of design activity. In recent years, research also became concerned with the exploration of the physical implications of digital media in the production of artefacts. Today, there is a vast range of research interests and approaches, but the quest for new, unifying paradigms continues.

title	VIRTUAL CONTEXT - INVESTIGATING THE CHARACTERISTICS AND OPPORTUNITIES OF DIGITAL VISUALISATION MEDIA FOR SITUATED APPROACHES TO ARCHITECTURAL DESIGN IN AN URBAN ENVIRONMENT
source	Delft University Press
summary	This research initiative addresses the issue of Design in relation to Virtual Context. Central to this study are the innovative potentials and instrumental opportunities of computer based media techniques, capable of generating interactive models and changing perspectives for the benefit of urban and architectural design. The ambition was to not only make a contribution to the existing body of knowledge concerning digital technologies and their applications, but explore theoretical conditions which might help define and stimulate further study. From the outset, the focus was on furthering the opportunities for computer based representation media in creative design. On the basis of a series of explorative studies the subject of this research was targeted: the issue of Design in Context, or more specifically: Design(ing) in a Virtual Context. During the process there was a marked shift in the conception of the subject from – more or less immersive – VR technologies in the direction of approaches which might be expected to become readily available in practice and education and could be effective in actual design processes. This insight also brought about a shift in emphasis from realism per-se towards creating a sense of situatedness. The design representation system which was developed was intended to not just allow for one type of model view, but to afford an array of different views, from which the designer would be able to choose freely, depending on the phase and focus of design as well as personal preferences. A series of interface prototypes and support tools were developed especially and successively tested experimentally. For the intended final design driven experimental study, different virtual context models were considered. Eventually, an integral – purely fictitious – design ‘environment’ was constructed in the computer, so that the workings of the proposed system and its components would be tested systematically. A conscious choice was made for an in depth study, on a relatively modest scale, which would a certain amount of mutual involvement between designer and researcher, to confront the participants with the finer aspects of the proposed system in a relatively short time and to gather detailed data. A half dozen design professionals were invited to participate in a closely monitored experimental exercise. The results of this study therefore do not offer straightforward, indisputable facts, to be considered representative for the design community as a whole, but indicate that the working methods of the individual designers – when discovering aspects of the site, developing and presenting proposals and reflecting on the qualities of represented designs – tend to vary considerably. For this reason the interactive representation system proved to be of value. Participants could express different view preferences, with more or less realistic image modes being used in different phases of their design developments, with varying experiences of situatedness. Some of the design professionals participants were very appreciative of the system’s opportunities, others tended to be more ‘set in their ways’. The results of this experimental study indicate that there may particularly be opportunities for interface applications which are able to function interactively, offering individual designers – as well as others involved in evaluating design proposals – a variety of tools with which to approach specific design artefacts in their changing contexts. Virtual models can play not only an important role as a ‘reminder’ for the designer but also to other parties playing an active role in the design and implementation processes. Interactive environment models are not only promising as exploration tools for existing sites, but could be valuable to test the impact of a design on its location. This could be especially interesting if the site is difficult or impossible to visit or as yet a virtual construction. In addition such an approach might be beneficial for objective comparison and evaluation of design proposals in competitions and in education as well as in on-line collaborative design projects where the context is still in the process of being developed.

title	Shape Knowledge Embedded in a Collaborative Virtual Design Environment for Architectural Design

summary	VR-based design environment have been traditionally not connected to companies’ design repositories and knowledge management systems. Till now these tools are mainly used for the initial exploration of innovative and original three-dimensional spaces and curves. Our approach encourages the use of VRbased design environments as design tools from where to reuse design solutions and to access design information, which are stored in internal repositories. This vision goes towards the development of a VR-based integrated design platform. Further, today’s knowledge management systems show evident limitations when dealing with multimedia files and 3D models. In order to overcome this limitation a framework for embedding in our VR-based design environment a Knowledge Management system for multimedia content has been developed and it is here described. Our solution implies the use of annotation languages such as the recent MPEG7 ISO/IEC (Multimedia Content Description Interface) standard for metadata, which is based on the XML language. Data types handled in our system are multimedia formats including text, audio, video, images, and 3D models. The main contribution of our research activity is in providing an innovative and original approach for supporting the design process, which takes advantage both of the visualization and design capabilities of virtual reality technology and of the reuse of design solutions directly in VE, through the retrieval of 3D models and multimedia data from various sources.

title	Adaptive Generative Patterns: design and construction of Prague Biennale pavilion
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This paper describes an experimental practice-based research project that considered design process, implementation and construction of a pavilion built to be part of the Performative Space section of the International Biennale of Contemporary Art, Prague 2005. The project was conceptualized as a time-bound performative situation with a parasite-like relationship to its host environment. Its design has emerged through an innovative iterative process that utilized digital simulative and procedural techniques and was formed in response to place-specific behavioral challenges. This paper presents the project as an in-depth case-study of digital methods in design, mass customization and unified methods of production. In particular, it considers the use of Voronoi patterns for production of structural elements providing detail on programming and construction techniques in relationship to design aspirations and practical constraints.

summary	This paper presents a parametric shape grammar that explains the generation of the structural forms of the Spanish designer Santiago Calatrava. The shape grammar is divided into two separate grammars a lower level grammar and a higher level grammar. The lower level or first grammar is composed of rules to generate a “fundamental unit” design, which has the characteristic to be a single component with non-repetitive parts that becomes the primitive object of the design. The higher level or second grammar is composed of rules that generate the overall design by recursive application of Euclidean transformations to the fundamental unit. We concentrate our discussion on the higher level or second grammar to demonstrate the process of generating complex designs by application of simple rules.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title	Skin That Fits: Designing and constructing cladding systems with as-built structural data
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 236-245

summary	An awkward interface exists between the structure and skin of complex architecture. The primary structure is typically allowed much higher tolerance ranges than that of the cladding industry, due primarily to the delicate nature of the building envelope which, above all, must prevent water penetration and meet the aesthetic requirements of the architect and client. As architecture has integrated advanced design and fabrication techniques to realize increasingly complex shapes, this problem has been aggravated because of the tangency requirements for high gloss curved finish surfaces and the larger variations found with rolled steel columns and undulating concrete forms. To date, most innovations in this area have been focused upon mechanical connections that can be adjusted and shimmed, thus requiring increased design engineering and on-site labor costs for effective implementation. It would be preferable to manufacture cladding components that are properly adjusted to the actual site conditions, negating the need to predict and accommodate potential dimensional variation with complex connections. The research provides a model for implementing long distance laser scanning technology to facilitate a real-time parametric BIM, herein called an Isomodel.

summary	This paper describes a studio experiment developed with the aim of exploring the design and fabrication of innovative roof systems based on ceramic tiles using digital technologies. History is rich in examples of the use of ceramic roof tiles since the ancient world. Today’s systems derive from such ancient systems and fall into several basic categories depending on the form of the tiles and how they interlock. These systems present acceptable functional performances due to centuries of refinement, but as they have suffered little formal evolution in recent centuries, to respond to modern needs they require complex layering and assemblies. Recent technological evolution has emphasized the optimization of the tile production process in terms of time saving and cost reduction, and the improvement of product quality in terms of material homogeneity and durability. Little attention has been paid to the tile form and the roof system as a whole, including the assembly process. As a result, despite the variety and performance of existing designs, they are often perceived as outdated by architects who refuse to use them following a stylistic trend in architectural design towards primary forms and flat roofs. The challenge of the experiment was to take advantage of digital design and fabrication technology to conceive systems with improved performance and contemporary designs. The hope was that this could lead architects to consider integrating roof tiles systems in their architectural proposals. Results yielded five different roof systems. These systems are innovative from a formal viewpoint both at the tile and roof level. In addition, they are easy to assemble and possess better thermal and water-proofing performance. Digital technologies were determinant to enable students to design the complex shape of the tiles, to manipulate them into assemblies, and to assess the shape of the roofs, as well as their thermal and structural performance in some cases.

summary	Design knowledge abstracted from cases is important for designers. This paper is aimed to build an agent to detect those correlations between explicit features of design cases and relevant design problems. Using the data mining algorithm, we have accumulated a list of keywords about design problems and their relevant concept from textual information of a case library, and established their semantic ontology by clustering their semantic and sentence structural relations from previous studies. Meanwhile, we also established another hierarchical ontology of explicit design case features by applying design domain knowledge. Then, through mapping semantic relations of relevant keywords between two ontologies, the system will become more sensitive to the correlations of design case features and relevant design problems. Finally, a graphical interface is built to visualize these correlations and help user to recognize useful design knowledge cached in design cases.

summary	The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.

title	Crisis? What Crisis?

summary	The paper describes the current situation concerning career opportunities in the field of architecture in developed western countries. Several aspects that are almost universal mark this situation. Firstly, there are too many architects chasing traditional work in competition with structural (civil) engineers. This is not surprising in consideration of the fact, that the architectural education industry produces far too many new architects for the economy to absorb. In Germany, the number is almost three times too many. Secondly, the needs of the building industry have changed over the past twenty years so that the skills that architects want to offer are not necessarily those that are sought. Lastly, the constant specialisation of work has continued unabated. Architects, as generalists, have idly watched their areas of expertise be usurped from neighbouring fields like civil and structural engineering The reasons for this crisis are manifold. In the schools of architecture, the discussions often deal with form or formal arguments, which, in fact, have little or no relevance to the building industry. This position was tenable so long as the clients were willing to accept formal arguments in order to receive buildings of high quality or current social relevance (i.e. current architectural fashion). With the dual aspects of globalisation and a shift to maintaining building stocks rather than producing new buildings, the tolerance for “architectural” discussions has been reduced even further. Indeed, the monetary pressures overwhelm almost all other aspects, including so-called green issues. What is more, most of the monetary issues are time based. Time represents, perhaps, the largest pressure in any current planning project. The clients expect expedient, accurate and inexpensive solutions. If architects are not able to produce these, the clients will (and do) go elsewhere. The authors argue that there remain serious problems to be solved for architects and the metier in general. Ever cheaper, ever faster and ever encompassing information technologies offer the architectural community a chance to turn recent trends on their head. By using information technologies to their full potential, architects can reassert themselves as the coordinators of building information and processes. Simply put, this means less photorealistic rendering and more databases, which may be unappealing for those architects who have positioned themselves as “designers” and are able to talk long on form, but short on cost or logistics. Nonetheless, the situation is not lost, so long as architects are able to recognise what is desired from the point of view of the client and what is desired from the point of view of the architect. It is not a question of one or the other. Architects must be able to offer innovative design solutions that not only address the fiscal, legal and programmatic constraints, but also push the boundaries at to the position of architecture in the community at large. For educators, it must be made clear that the real potential architects possess is their encompassing knowledge of the building process including their expertise concerning questions of architectural form, function, history and art. Precisely while they are generalists are architects invaluable in a sea of specialists. The biggest hurdle to asserting this in the past has been the control of the vast amounts of information. This is no longer a problem and also no longer an excuse. In the education of architects, it must be made clear that their role dictates sovereignty over architectural information. Architectural Information Management is a necessary skill alongside the more traditional architectural skills. A brief outlook as to how this might come about is detailed in the paper. The authors propose didactic steps to achieve this. Primarily, the education of computer supported planning should not simply end with a series of lectures or seminars, but culminate in integrated Design Studios (which including Design-Build scenarios).
