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	Digital Fabrication Production System Theory: Towards an Integrated Environment for Design and Production of Assemblies
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	A Digital Fabrication Production System (DFPS) is a concept describing a set of processes, tools, and resources that will be able to produce an artifact according to a design, fast, cheap, and easy, independently of location. A DFPS project is a complex assembly of custom parts that is delivered by a network of fabrication and assembly processes. This network is called the value chain. The workflow concept of a DFPS is the following: begin design process with a custom geometric form; decompose it into constructible parts; send the part files for fabrication to various locations; transport all parts at the construction site at the right time; finally, assemble the final artifact. Conceptually it means that based on a well structured value chain we could build anything we want, at anyplace, at controllable cost and quality. The goals of a DFPS are the following: custom shapes, controllable lead time, controllable quality, controllable cost, easiness of fabrication, and easiness of assembly. Simply stated this means to build any form, anywhere, accurately, cheap, fast, and easy. Unfortunately, the reality with current Digital Fabrication (DF) projects is rather disappointing: They take more time than what was planned, they get more expensive than what was expected, they involve great risk and uncertainty, and finally they are too complex to plan, understand, and manage. Moreover, most of these problems are discovered during production when it is already late for correction. However, there is currently no systematic approach to evaluate difficulty of production of DF projects in Architecture. Most of current risk assessment methods are based on experience gathered from previous similar cases. But it is the premise of mass customization that projects can be radically different. Assembly incompatibilities are currently addressed by building physical mockups. But physical mockups cause a significant loss in both time and cost. All these problems suggest that an introduction of a DFPS for mass customization in architecture needs first an integrated theory of assembly and management control. Evaluating feasibility of a DF project has two main problems: first, how to evaluate assemblability of the design; second, how to evaluate performance of the value chain. Assemblability is a system’s structure problem, while performance is a system’s dynamics problem. Structure of systems has been studied in the field of Systems Engineering by Network Analysis methods such as the Design Structure Matrix (DSM) (Steward 1981), and the liaison graph (Whitney 2004), while dynamics of systems have been studied by System Dynamics (Forrester 1961). Can we define a formal method to evaluate the difficulty of production of an artifact if we know the artifact’s design and the production system’s structure? This paper formulates Attribute Process Methodology (APM); a method for assessing feasibility of a DFPS project that combines Network Analysis to evaluate assemblability of the design with System Dynamics to evaluate performance of the value chain.

summary	Urban design involves coordination and communication for collecting consensus among citizens and developing the design strategy and spatial program. While these are web-based systems for representing the real world actions, there is lack of human interaction for receiving feedbacks during the process. Therefore, the purpose of this study is to introduce the agents into the participatory design process (PDP) based on scenarios. This paper has developed a webbased system prototype to demonstrate how the agent can interact with users and how the interface facilitates incremental design. We present a participatory design project in an old street to illustrate how the Scenario-Based Agent System (SBAS) model functions in a real application. Meanwhile, four issues will be discussed in regarding with building a learning interaction agent as an actor.

title	CONTEXTUALIZATION AND EMBODIMENT IN CYBERSPACE
doi	https://doi.org/10.52842/conf.caadria.2004.005
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 5-14
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.

summary	Academic publishing started in the hands and under the control of learned societies. Open access to digital publications has the potential of returning control to these associations again. In this paper CAAD-related digital library pilots, which were developed in the framework of the SciX-project (“Open, Self Organising Repository for Scientific Information Exchange”) will be elaborated. SciX focused its work on the infrastructure and business models for subject-specific repositories. Electronic publishing can re-establish the central role of scientific communities and associations in the scientific publishing process.

summary	The article describes the didactical integration of wireless access networks for the campus of the University of Karlsruhe in the education of architects and engineers. It focuses on the development of an interdisciplinary communication network to encourage, support and promote the communication and collaboration between students. The discussed modules were developed during the Notebook University Karlsruhe (TH). An applied project, aimed on several targets. The invention of a notebook university for all students. The distribution of software via a „software fuel station“, the integration of UMTS in campus networks, the support of online lessons, and the encouragement of students to work over the internet. The author joined the consortium with the subproject called: „Interdisciplinary Cooperation Modules in Mobile Networks“ (INKOP). This project lead to a couple of tools, listed in this contribution. Based on the design and project oriented cooperation platform netzentwurf.de the authors developed the tools „Jobadmin“ to administrate multidisciplinary workgroups, „Swarm Knowledge Catalogue“ to collect and store knowledge and „LivingCampus“, an instrument providing basic services for dynamic communication. The author assumes that the fundamental learning impulses take place among the students themselves and that the training of architects and engineers should enable them to organise themselves and their workgroups. Therefore, the collective acquisition of knowledge and cooperation has to be trained during the studies closely.

summary	This paper focuses on a lightweight ontology-based knowledge management system, which is a prototype that aims at enhancing the collaborative activities in the early building design phase. Technologies with respect to de facto standards proposed by industry group W3C are implemented to develop this knowledge management system. Resource Description Framework (RDF) associated with its Schema (RDFS) is selected as the ontology language used in the system. RDF(S) with its embedded reasoning techniques provides a rich set of constructs to facilitate the generation of ontologies so that the annotated information can be machine readable. Approaches of how the domain knowledge is represented in RDF(S)-based ontology, is shared and retrieved among stakeholders of building project will be described and illustrated in the paper. A proposition with respect to the contribution of this prototype system to collaborative activities undertaken in the early building design phase will also be discussed in the paper.

title	A model proposal for digitisation and recording data on architectural heritage in Poland based on European guidelines and best practices.
source	University of Strathclyde, Dept. of Architecture and Building Science, Glasgow UK
summary	The aim of the research is an adoption of digital technology in the recording and management of architectural heritage of Poland. The current documentation practice does not fit to the present needs. The existing system of built heritage recording and protection in Poland was developed during the 1960s and the 1970s. It is based on a database of paper fiches. Although the documenting template allows the collection of comprehensive information on historic buildings, the whole system of heritage protection remains petrified. The database verification and upgrade is usually delayed, and moreover, the records do not include some information crucial for successful protection and regeneration of historical buildings. The lack of computer aided documentation system causes, furthermore, inadequate management of the heritage. Central to the research methodology is the belief that a computer aided documentation system for built heritage in Poland should be compatible and harmonised with similar European projects as a response to the needs of the emerging Information Society. To achieve that standards and best practices in Europe were identified, analysed and compared with the current Polish system of heritage protection and management. Activities of Scottish organisations from the cultural heritage sector, being in the forefront of European achievements, were studied in detail. It was observed that Scottish advancements might be a source of valuable lessons and guidelines for similar activities in Poland. The issues crucial to designing a framework model for digitisation and recording data on architectural heritage in Poland were given particular attention. These included aspects related to content, technology, legislation, and project organisation. As a result a number of recommendations were formulated and supported with necessary tables and diagrams. This specification is intended as a starting point for implementation of digital technology in recording and management of architectural heritage of Poland. It is believed that the research outcomes may become useful not only for the architectural heritage documentation and management, but also in the wider cultural heritage sector in Poland. The thesis concludes with a statement that the validity of any guidelines related to the digital technology has a limited lifespan, and therefore the proposed model for digitisation and recording data on architectural heritage in Poland, to be successful, requires constant, diligent review of the technology development.

summary	This paper explains the results of a collaborative research project between Multimedia University (Malaysia) and Innotive Corporation (Korea) to manage, design a multimedia archiving system and visualising knowledge for the students or the users in the Faculty of Creative Multimedia, Multimedia University. This research introduces InnotiveBrowser technology, a high performance multimedia display software that enhances the ability of user to search and discover digital content. The unique result of this method is that the images to be viewed are not limited to available RAM, instead the content utilises the available storage directly from the disk (hard drives). In other words, the larger the size of the hard disk, the greater the number of content information can be stored and displayed. This system is employed with Virtual Reality (VR) techniques particularly imparting viewing technology (pixel-ondemand) and navigation strategy to increase the viewing speed of multimedia information in real-time over the Internet, broadband and even via PDA platforms. This research hopes to set the benchmark for multimedia archiving system that can be applied in other CAD, CAAD or most of the design or production-based teaching and learning environment. The early findings of this research have been patented and this paper will demonstrate the research ideas and explain how we implement and customise the technology and content development in the Faculty of Creative Multimedia, Multimedia University.

title	Using Computers as a Spatial Visualization and Design Exploration Medium
doi	https://doi.org/10.52842/conf.ecaade.2004.325

summary	The constant advances in the use of computers to simulate light over the past few decades, has led computer-aided rendering to become increasingly photorealistic. However, the rendering is still processor-intensive and time-consuming, difficult to generate in real time. Design students need to be well versed in the depiction of the effects of light in an environment, crucial to spatial visualization. With increasing computing power, advanced algorithms and increased realism, the central pedagogical issue in their use is not what computers can do for us today, but what and how we can make them do what we do better. We have to be careful in not getting seduced by the advancing technology but use it innovatively to build students into better designers. This paper discusses a project demonstrating the apparent potential of computers for spatial visualization and design exploration of light and space, in their present stage. The project shows a departure from the traditional methods of using computers or of teaching lighting in a design school. Computers are used by students to especially create flashy imagery. On the other hand, lighting is explained in clinical terms without exploration of its experiential qualities. This exercise helped the students to develop a better understanding of the physics of light from the method most familiar and expected of students – visual. The project deems it more important to have a quick means to produce an overview of the implication of the design choices than to provide precise information regarding a hypothetical final solution. Hence, after creating the lighting in the space based on the desired experiential qualities, the illumination can be conveyed to a lighting expert for detailed quantitative computations. The project results are shown and outcomes discussed.

title	Untimely Fabrications
doi	https://doi.org/10.52842/conf.acadia.2004.052
source	Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 52-65
summary	The value of material in architectural practice is determined not by its character but by functional performance and economy. In early modernist thought, part of this motivation was to liberate construction from the ‘burden’ of aesthetic speculations and return it simply to the concerns of building. Any artistic agenda became embedded in the economic and productive processes of the project. Authenticity emerged out of the need to focus on the essentials and reject the superfluous. However, this demand for truth in materials has long since been compromised by the climatic requirements of building enclosure. Most contemporary practice in architecture is derived from principles of cladding where the ‘essential nature’ of a complex building requires concealment. The communication of the building is expressed in the refinement of the layers that make up the surface. This shift from the emphasis on making and the idea of ‘material’ in architecture, to one of perception and ‘materiality,’ has an important corporeal dimension that parallels the material aesthetic practices developed in art and sculpture in the 1960s. In this sense, Fabrication carries an ‘untimely’ dimension. This paper proposes to look at the work of a broad range of architects, both well-known and not so well-known, in light of these artistic-based approaches to materiality. Digital fabrication opens a new chapter on this debate and it remains to be seen how this economically useful approach to construction changes, once architects investigate the visual characteristics of materials and methods of fabrication.

title	MATHEMATICS FORMATION AND CREATIVE DESIGN
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 225-229.
summary	One of the earliest human beings desires has been to inhabit a place that may assemble beauty and functionality. Architecture and Design have been the disciplines in charge to formalize it. Their study, as well as the way they are taught have been adapted to fit the needs; and the velocity of their transformation is even greater as well as the link between design, art and technology. Creativity, in it basic generic entity, is the capability to solve appropriately and originally phrased architectural problems which involves not only space, act, environment and semiotics but with everything related to make the project able to be constructed and inhabitable. New technologies are based on complex algorithms which, by the use of simulators, achieve to produce complexity works that would have been unbelievable twenty year ago. These algorithms have a strong mathematical basis and allow to generate other working methods so as to create wonderful geometrical objects. The study of this New Geometry requires to explore and expand this field of knowledge in the Architecture studies. In order to analyze and use complex design systems to generate non linear experimental models, it is necessary the Mathematical contribution, not only at the University education stage but also at the professional life. This New Mathematics adequately focused, is able and must be an essential ally to creative design which is born with an exercised imagination in the formation stage; therefore it must aid to establish a space where knowledge and ability for architectural work can be created, synthesized and experimented. This work tries to encourage students and in relation to Geometry promotes the following aspects: (i) Inspection of new architectural spaces, (ii)Comprehension of the geometrical structure, (iii) Originality and common sense, (iv) Relation between Geometry and design of construction constitutive elements,(v) Insertion of man in the space, (vi) Conditioning of design to human body dimensions, (vii) Fractal geometries. According to what has been expressed, this proposition acquires a fundamental significance to develop a spatial vision of geometrical shapes in students, in order to stimulate the understanding of the existing relation between abstract geometrical elements and their real applications in Architecture, Geometry and Design and Art. Besides, the purpose of this work has the aim to approach knowledge at the architectural design process and to the study of shapes and mathematical models that such designs sustain , and ultimately demonstrate the importance of an academic organization that involve teachers from different disciplines.

summary	This study presents the results obtained as of the teaching of architectural project at a digital workshop using the WEB environment and its graphic and textual interaction tools. Sketches and external and internal 3D modeling of the architectural object formed the corpus of this investigation. The architectural concept phase (generation of ideas) was given pedagogical emphasis, based on a core concept established by conceptual images and to which space, software and formal construction elements are subordinated. The computational tool was seen to become one of the agents in the idea generation process by assisting in the arrangement of the designer.s initial ideas and by establishing project procedures that use computer-based operations. These project procedures reconstruct the object perceived as architectural concept. The central notion in the architectural proposition is the decisive element in the choice and use of the graphic software in the design process, considering its different steps.

summary	With the continuous advancement of scientific knowledge more attention has been paid to the accuracy and consistency of graphic representation in Science Education. In addition, the dissemination of web based distance education has increased the development of new educational material and tools; nevertheless many of them have poor efficacy due to the lack of a design that integrates the interdisciplinary needs of the educational project into product planning and development. This paper presents the results of the design of a constructivist computer based learning environment (WEB based or CD-ROM) aimed at the teaching and learning of Classic Genetics. The analyses of results revealed that the prototype design was approved by specialists in the fields of Genetics, Educational Technology, and Informatics; it was also perceived as a powerful learning tool by students.

title	SPECIAL ISSUE ON „DIGITAL MEDIA LIBRARIES“
source	ITcon Vol. 9 (2004), pp. 97-174
summary	There are numerous commercial digital asset management systems, but most of them are relatively expensive and meant for in-house management. In the meanwhile alternative solutions have been developed for searchable interactive repositories of media for professional use, education and research. Web-based digital libraries and indexes of literature have been available on the internet for a few years now. In many cases a focus on specified areas is given and published information is disseminated in this way. However, researchers, educators and practitioners in architecture and civil engineering also depend on various sources of information that are stored and delivered in a multitude of media formats. Some of that information is case-based and built incrementally from previous experiences.

summary	This paper exposes site .Cidade Interativa. development process, based on: a reflection about importance of users. points of view.s incorporation for space remodelling; a study about theoretical and practical experiences which, in different ways, approached potencialities of participation of a community.s members in a project; and, finally, a investigation of propagation alternatives of individual readings as information source for urban project, trying to enhance points of view that generally remain occult in the form of invisible practices of anonymous users. This site must be understood as concretion of an idea: creating a vehicle from which is possible to become individual readings public, so that these are shared and, also, make them available to people responsible for urban projects as information source.

title	Hybrid Approach to Solve Space Planning Problems in Building Services

summary	In this paper an object-based CAD programming is used to take advantage of standardization to handle the schematic design, sizing, layout for services in a building ceiling void. From the specification of the building 3D model, our software proceeds through different steps; from the determination of the standard number and size of fan coils to the generation of 3D solutions. In order to deal with more complex geometry and larger problems, we have used a hybrid approach: Case Based Reasoning (CBR) within Constraint Satisfaction Problem (CSP) approaches. In practice, engineers in building services use previous solutions and adapt them to new problems. CBR mirrors this practical approach and does help us to deal with increasingly complex geometry effectively, and meanwhile CSP has been used for layout adaptation. The results have shown that it is possible to define and implement standard solutions to produce designs comparable with current practice. The benchmarking exercise has underlined many advantages and made some suggestions for further development. This project is funded by The Engineering and Physical Sciences Research Council (EPSRC) in UK.

title	Mindful Spaces: Computational Geometry and the Conceptual Spaces in which Designers Operate
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 611-624
summary	Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

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.
