summary In this paper we view the process of collaboration as a social setting, rather than a problem of communication. It involves and is impacted by social, non-technical aspects, such as lack of shared understanding, conflict, availability and motivation of the participants, and other factors that can facilitate or impede the goals of the collaborative enterprise. We propose to use a social and psychological approach. The ideal model should be a collaborative design system that can facilitate the socially constructed interactions among participants, as well as the communication of information. The proposed system should enable participants to assess the typical problems of collaboration. We build up our effort towards this goal by developing a representation system of collaborative design process. In this research we attempt to map collaborative design process into process design by using our proposed representation system. Our intention is to enable the existing system visually representing the integration of design stage to the whole construction process: since project planning until building operation.

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 “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ 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’s 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 Analysis of Design Support for Kinetic Structures
source Vienna University of Technology; Building Science & Technology
summary This thesis attempts the formation and systemization of a basis of knowledge and information, which is indispensable to turn a design support for kinetic structures into representation by means of a 3d animating program. Representation of kinetic structures by means of the existing ordinary software sources is possible; Nevertheless, such representation lacks of different important features and functions and results eventually in the total absence of a real model of the construction, which is valuable to the user of the program especially in the field of the kinetics, where everything depends on the movement: design not only requires, but demands for visualisation. A personal interest in kinetic architecture and therefore in the physical movement of structural elements in a building, as well as an attempt to “fathom” the possibility of changing this concept to visualization and modern reality by the use of a software are the main incentives of this master thesis. First, a general research will be performed in order to check the existence of similar or semisimilar proposals. The area in which the research will be held is the Bibliography in kinetic architecture and parametric design. A comparison of animation and 3D prototype software in well-known programs will focus on whether virtual weather conditions are considered as a parameter to the animation of the structure of the programs and case studies of several existing kinetic structures will be performed, in order to point out flaws and/or helpful commands in the programs in connection with the presentation of kinetic architecture. Criteria for the choice of the software: ability to customise and to produce geometric modelling, animation in relation to time (video animation) and the simulation after taking into consideration weather factors. Finally, using the computer and the scripting language, based probably on the theory of parametric design and primitive instancing, a realistic simulation of different elements will be performed in relation to variable measurements of luminance, ventilation and temperature so as to render feasible the construction of a whole structure. The results of the thesis will be used in the future as the basic knowledge in the creation of software for simulation of kinetic architecture. This program will be used as a tool for the architect to present a building, where kinetic architecture will be applied and to create simulation of the kinetic movement through a library of the existing prefabricated elements which will be created with the help of this thesis.

title Choosing Levels of Granularity in Building Information Modeling: Contractor’s Perspective
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 623-634
summary Over the last two years, there has been an increased interest across the Architectural /Engineering/ Construction (A/E/C) professionals in the potential adoption of the Building Information Modeling. Professional Associations such as the American Institute of Architects (AIA), the Associated General Contractors (AGC) and the Design-Build Institute of America (DBIA) are dedicating specific resources to better understand the implications of the use of this concept in their professional activities. However, not much ground has been gained yet in finding practical ways to choose the level of granularity (LOG) or detail that is needed to develop the digital model in a cost effective fashion. Choosing the Level of Granularity (LOG) of the digital model or level of detail development that goes into the model is a key decision that results from careful consideration of many factors. It is a very complex and iterative process that requires a critical assessment of the cost of adding details to the digital model versus the benefits derived from its intended purpose whether the model will be used to enhance the communication process or to support the construction management functions performed by the firm. This paper presents two case studies in which the authors have been directly involved in making the decision on the LOG of the digital model. The first case involves the Togar Suites, Union Station project in New Jersey while the second case refers to the Worcester Trail Courthouse in Worcester Massachusetts. In both cases, the 3D models were developed primarily for visualization of the construction sequence. However, in the case of the Togar Suites the contractor also needed the model for trade coordination and clash detection purposes.

title A framework towards designing responsive public information systems
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 767-782
summary "Evolving effective responsive systems, and creating a credible interface between the work and the user, requires an awareness of many different types of user, contexts and functions as well as the phenomenological aspects of social and environmental conditions." (Bullivant, 2006). Responsive design and interactive architecture operates at the intersection of Architecture, Arts, Technology, Media Arts, HCI and Interaction Design in a physical context suggesting ways in which the existing physical environments can be augmented and extended adding a greater level of depth, meaning and engagement with the world around us. Through a series of case studies, this paper explores a number of principles which may be applied to the design of responsive environments of which public information systems form part. Divided into three main sections, the paper first explains how responsive environments have addressed the application of public information systems, secondly, through a series of case studies, precedents are highlighted which lead to development of principles for developing designs for responsive environments. The third section discusses and elaborates on these principles which have been developed based upon our own interpretations and grouping of precedents and approaches towards interaction design. This paper contributes towards the field of responsive environments and interactive architecture through an analysis of case studies to infer a framework from which responsive environments may be created and developed.

title A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary Architects—like other designers—tend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses—in the way architecture is conceived, taught and critiqued—results in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as “movement”, “guiding” and/or “rest” plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title History and 3D City Models: An Analysis of Digital Representations of the City Evolution
doi https://doi.org/10.52842/conf.caadria.2007.x.h2u
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary Through the evaluation of advantages and limitations of 3D historic city models, this paper aims to analyze the contribution of those tools to the city history representation. One should overcome limitations such as incomplete information, impediments to acknowledge hypotheses representations, intense labor requirements or difficulties to encourage a historical reflection. We argue that creative systems that are carefully planned towards history’s thorough understanding are more effective than those applications which focus on the development of high quality images. Those issues are illustrated by the system prototype “Rio-H”, which presents an alternative to communicate the history of Rio de Janeiro, Brazil.

summary In this paper we discuss the parallels between architectural design and strategic marketing in industry to advance the theme of predicting the future in architecture. Just like companies face the challenge to organize their R&D activities, architects develop different strategies for their designs. Looking at the architectural design process as well as at strategic planning done in companies we recognize that they have much in common. To advance the theme of predicting the future in architecture we draw parallels to strategic marketing in industry. Both activities require a clear vision regarding customer requirements, available technologies, and areas of operation and emerging markets. We report on a successfully implemented method Pictures of the Future at Siemens and relate it to architecture and show possibilities to expand the role of architectural design in the future. We opine that it is now time to expand the architectural curriculum towards Knowledge Architecture.

title Architectural eLearning: An inquiry into the fuzzy boundaries that separate education and instruction [Architectural eLearning. Una indagación sobre los límites borrosos que separan la educación y la instrucción]
source SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 155-158
summary This communication is based on the development of a new subject to be imparted in collaboration with three Departments (Visual Communication, Projects and Construction) at the School of Architecture of Barcelona. It is a work that has been financed with a special grant from our university, aimed at the development of new teaching modalities and, in particular, of those that would develop the use of new technologies, collaboration among university departments and eLearning. The aim of the communication is twofold. First, to present some results that we consider valuable in themselves, as much for the techniques as for the methodology that we have used. Second, to propitiate a debate on the new situation that the teaching of architecture is moving to, due to the advance of a series of instruction methods where the methodological organization, the storing of informative material and the preparation of autonomous interactive systems, open more and more effective roads of learning but that, at the same time, point towards a new educational structure that fits badly within the traditional structures in which we have still to work daily. Regarding the first point, the main aspects to highlight are: a) the development of a selflearning system by means of a very complete series of tutorials that allow a gradual acquisition, depending on the necessities or interests of each student, of geometric modeling, parametric design, visual simulation and interactive animation techniques, b) the development of a system of general information supply and on line comments and corrections. Regarding the second point, a provisional theoretical framework has been elaborated based on the consideration of the ubiquitous visual communication media as misleading mediators of a personal relationship. This theoretical frame has been tested by a few experiences carried out with the collaboration of students implied in the project. The general conclusion is that both challenges must be faced at the same time: new educational technologies must be analysed and integrated in our curricula and a new theoretical framework, able to clarify the difference between instruction and education, must be developed in parallel with those technologies.

title Towards a Graphic Design teaching methodology, based on a system of perceptual tools for digital visual codification [Hacia una metodología de enseñanza del Diseño Gráfico, basada en un sistema de herramientas perceptuales de codificación visual digital]
source SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 121-126
summary New requirements from the "Visual Information Society" motivate the creation of strategies for the teaching of digital design as a professional skill. Here we describe a computer-mediated experience with a learning method addressing a strategy of digital visual codification in initial workshops of Graphic Design. The strategy is based on a “system of perceptual tools for digital visual codification”, categorized into semiotic foundations, which allow the student to address visual communication through digital design with normalized criteria and creative openness. This enables the student to develop competence in visual digital communication and self-assessment of both process and result.

summary The distinction between matter (mechanics) and information (electronics) in the context of responsive building skins has promoted unique design protocols for integrating sensor technologies into material components. Such a distinction results in applications of remote sensing after the process of material fabrication. Sensors are commonly perceived as electronic patches which initiate mechanical output with response to electrical input. This work seeks to establish a novel approach to the application of electronics in building skins, which prioritizes material selection, behavior, and fabrication technology in relation to the required task, over postproduction sensor integration. The term “Rapid Craft” is proposed to describe such design protocols which couple material behavior and fabrication in the design of responsive skins. Rapid Craft is a designation for the incorporation of craft materialization knowledge within the framework of CNC processes of fabrication. A light-sensing inflatable skin system is developed as a working prototype, which demonstrates such an approach.

summary Building Information Modeling (BIM) obfuscates the role of composition, scale and abstraction by displacing the primacy of abstract conventions of representation with a methodology based on simulation. BIM subverts, while simultaneously clarifying, the holistic relationships of the parts to the whole in the architectural design of form and space. Architectural design education has great opportunity and risk in how it comes to terms with re-conceptualizing design education pedagogy as the profession struggles to redefine the media and methods of architectural deliverables in the age of BIM. The paper examines the foundation issues proposed by Integrated Practice. The paper questions how BIM and modeled simulation of architectural assemblage might transcend current definitions of convention in design and construction representation. This paper explores how the academy might prepare students of architecture for a digital practice that focuses on the virtual building model and database management. BIM and Integrated Practice viewed as provocateurs of design education provide great potential for critical analysis of how architectural design is taught. The associated pedagogies are transforming the way in which architectural education engages issues of design and representation and creates opportunities to question the roles and rules of traditional conventions. The paper seeks to engage issues of design specificity and ambiguity related to the assets and liabilities of digital modeling as the primary means of design and representation that BIM represents.

source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary This research paper proposes a simulation software development for possibility analysis of urban landscape development project. Normally, analysis of land potentiality and feasibility study for investment are necessary pre-processed for supporting urban planning, developing and architectural designing. However, most available tools are usually tailor made for each process individually, causing difficulties in information interchange between each processes. In this research, we propose a policy making support system for urban planning project development providing several functions such as testing land use and its physical character which are important to urban expansion and architectural design based on impact analysis of urban comprehensive plan. The proposed integrated system consists of a topological analysis module, constraint checking module and geographical information processing module. First, Geographical information stored in 3D graphic file format is converted to object-oriented data model and stored in a database. With several constraint and regulations, the stored information is then checked in the landscape topological analysis module. In evaluation process, the developed software is tested with geographical information of Bangkok area under constraints and regulations of Building Control Act of Thailand. While controlling building properties, the software can model the buildings and generate urban physical character. The result is then checked by several urban landscape planning experts. Experimental result shows that proposed system provides flexibility in information interchanging with constraints and regulations updating without system reconfiguration. The system also provides internet accessing for public participation in the process of making urban comprehensive plan.

source Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 125-131
summary The paper presents on-going research aimed at the support of the management of building projects and the aid cooperative design. Today, The use of systems adapted to the cooperative design assistance for the building domain is complex. This results from the complexity of the cooperative work (difficulties in tracking actor’s work, lack of most of the required information, coordination problems, implicit nature of most of the construction activities etc.) The paper will briefly review two data exchanging modes that we had defined. After, on the basis of this concept of cooperative design we describe a new model of a virtual environment aimed to takes into account the relational organization of the project and the semantic meaning of works. This research represents a new approach because it not based on management of documents but on all data relative to works. Finally, we use this new model for defining a design-aided tool, to deduce advantages and limits of the “Virtual Cooperative Project”. This system lets geographically dispersed project actors model the project context of a building. More specifically, it allows interpreting, using and exchanging project works in a centralized virtual environment during the building life cycle. This system uses IFC objects which associate in the same model the semantic and the 3D representation of building works.

title Multi-touch - the future of design interaction

summary The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

summary This paper intends to analyze, compare, understand and explore the data relations among a collection, the collected items and user-created meaning appearing in different digital applications. Details of such relations are introduced and investigated with reference to several actual systems. In order to represent these three components in a way easy for users to interpret, navigate and interact, we introduce NEAR, a localized graph visualization tool to help people browse, understand and manipulate information in a digital architectural repository A•VI•RE.

summary Today’s typical decision making problem such as strategic planning, portfolio analysis, resource allocation and human resource management involves a variety of tangible and intangible strategic goals, conflicting constraints, dozens or hundreds of alternative initiatives to be pursued, and limited resources. A decision maker cannot meaningfully combine all of this information to make right decisions. To sustain decision makers in the Architecture, Engineering and Construction (AEC) industry, this paper proposes a tool to transfers a complex problem into a concept of hierarchical structure consisting of goal and its criteria and sub-criteria. Irrespective of the applied domains, this tool provides a flexible means for tackling the complex decision making process. It embeds a mathematical model for prioritization and decision making which is based on the Analytical Hierarchy Process (AHP).

summary By integrating the nature of modularity in prefabricated housing design, a web-based design advisory system provides interactive questionnaires to assist customers in selecting appropriate design components. The prototype model combines the result of client’s requirement input and design configurations of a modular system. The digital model is created by Building Information Modeling (BIM) applications to streamline the delivery process from design to manufacturing. Finally, the BIM design model can be reviewed via Google Earth before sending the ready-to-build digital information model and building specifications to the collective manufacturers and suppliers.
