title	A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source	7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary	In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.

summary	This paper presentation presents an interdisciplinary research project conducted by a design team comprised of faculty from the Colleges of Architecture, Engineering, and Astrophysics. The title of the project, Deep-Time Probe, Investigations in Light-Architecture, explores the use of an optically active-SETI experiment that centers on the thematic of time, vision, and movement through space. The realm of architecture was the digital glue that united the varied disciplines. The core of the project is broken down into three intrinsically linked components—data representation—collection, storage, and modulation; the Project Mission Wall; and the resultant Light Architecture or Deep-Time Probe. A small team of architecture students under the direction of one architecture faculty member designed the Mission Wall while the Robotics Department provided CNC machinery to digitally mill and fabricate its components. This same team assembled the 40’x60’x15’ structure in one day. The site of the launch created an adequate interface for the public art structure at the scale of an urban park. The scale of the Mission Wall addressed a variety of places, paces, and scales that mediated between the laser, the context of the surrounding plaza, and pedestrian and vehicular circulation, all while concealing the laser from direct view. The Mission Wall served three functions. It provided a housing for the Deep-Time Probe laser. It created windows and scaffolding for lighting. Moreover, it established a series of “View Corridors” that provided the onlooker with multiple vantage points and thus multiple-readings of information as architecture. Nearly fifty “Time Probe Reporters” gathered information through oral interviews. In addition to messages linked to the interviews, the Deep-Time Probe contained verbal and graphic information, images depicting the design and fabrication processes. At the time of the launch, the design team digitized, specially formatted, converted, and modulated the data into a special high-powered laser that was “launched” into space. An advanced civilization in the universe could theoretically receive and decode this information. The Deep-Time Probe project visualized the strengths of each profession, fostered the creative aspects of each team member, and resulted in a unique and dynamic experience. The deep time probe is right now passing through the Oort Cloud, the debris left over from the formation of our Sun and planets, present as a halo surrounding our solar system . . . a distance of nearly 1.5 trillion miles.

title	A FRAMEWORK FOR BUILDING DESIGN PROCESS MODELING WITH PARAMETER-BASED DESIGN STRUCTURE MATRICES
source	In C. J. Anumba (Ed.), Innovative Developments in Architecture, Engineering, and Construction. (pp. 25-31). Rotterdam: MillPress
summary	Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is utmost important. While the knowledge needed for building processes are distributed among the different participants from diverse disciplinary backgrounds, the product of their activities, i.e. the building itself, must be highly integrated. Despite the intense flow of information between design professionals, there is a lack of research to better understand and manipulate these flows. Furthermore, most of the current process modeling tools in the AEC industry do not enable analyses of iteration in the process and they represent the process at high levels with very little information at lower levels. In order to resolve the issues mentioned above, this paper introduces the use of parameter-based dependency structure matrix as a process modeling and system analysis tool for building design. The method reveals insights into the process structure, optimum sequence of parameter decisions, iterative cycles and concurrency in the process. A knowledge management framework for parameter-based DSM applications is proposed and the application of the framework is demonstrated through a real life building design problem.

title	Monitoring the Dynamics of Informal Settlements in Dar Es Salaam by Remote Sensing: Exploring the Use of Spot, Ers and Small Format Aerial Photography
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Dar es Salaam is exemplary for cities in the developing world facing an enormous population growth. In the last decades, unplanned settlements have tremendously expanded, causing that around 70 percent of the urban dwellers are living now-a-days in these areas. Tools for monitoring such tremendous growth are relatively weak in developing countries, thus an effective satellite based monitoring system can provide a useful instrument for monitoring the dynamics of urban development. An investigation to asses the ability of extracting reliable information on the expansion and consolidation levels (density) of urban development of the city of Dar es Salaam from SPOT-HRV and ERS-SAR images is described. The use of SPOT and ERS should provide data that is complementary to data derived from the most recent aerial photography and from digital topographic maps. In a series of experiments various classification and fusion techniques are applied to the SPOT-HRV and ERS-SAR data to extract information on building density that is comparable to that obtained from the 1992 data. Ultimately, building density is estimated by linear and non-linear regression models on the basis of an one ha kernel and further aggregation is made to the level of informal settlements for a final analysis. In order to assess the reliability, use is made of several sample areas that are relatively stable over the study period, as well as, of data derived from small format aerial photography. The experiments show a high correlation between the density data derived from the satellite images and the test areas.

summary	This paper deals with the CUMINCAD-repository (Cumulative Index on CAD), which was set up in 1998 and has served the CAAD-community since then as an important source of archived domain related information. CUMINCAD contains over 5,000 entries in the form of publications in the field of Computer Aided Architectural Design. The number has been growing steadily over the years. To date only advanced search mechanisms have been provided to access these works. This may work out well for a just-in-time location of a reference, but is inadequate for just in case browsing through the history of CAAD. For such applications, a hierarchical browsing interface, like one in Yahoo or DMOZ.org is envisioned. This paper describes how the keyword categories were defined and how a moderate, distributed effort in defining the categories will allow machine-identified classification of the entire data set. The aim of the paper is to contribute to building up a wide spread consensus on what the appropriate keyword categories in CAAD are, and what sub-topics should sit below the main keyword categories.

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.

summary	Outline of development of a revised base ITC course at the Faculty is shown here. The course, called Introduction To Information Technology Implementation is aimed for 2nd year students (3rd semester) of the study. For the first time it was held in the winter semester of 2002/03 as a pilot course replacing the old way of course delivery. This implementation was carried out through a “pathfinder” project WORMES from February 2002 till March 2003 and would be used as a template for future Hyperlearning implementation on other courses through other Faculty education programes. The objective was to establish continuous students teamwork around a problem – a project completely accomplished in IT surround. A slightly adapted methodology known as Hyperlearning – a version of Problem Based Learning, was chosen as a based learning methodology for a new way of course delivery. The gained results were really impressive. Not only efficiency of delivery was increased in many ways (less hours spent on exercises, better knowledge detaining...) but also huge enthusiasm among students was constantly maintained and their creativity was emphasized surprisingly. A lot of data were collected, analyzed and some of the results are published here.

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.

source	Scientific Bulletin, Faculty of Engineering, Ain Shams University, Vol. 38, No. 2, June 2003 - pp. 297-310
summary	Expert systems are computer systems developed to preserve the human expertise about specific domains in a well-structured form suitable for retrieval and manipulation by computers. They have been used in many fields of applications and proved to be beneficial. This paper addresses the role of Knowledge-based expert systems in building construction; particularly in the diagnostics and assessment of buildings' cracks. The paper presents BUIL-D-EX; a prototype for a Buildings’ Diagnostics Expert system intended to assist architects, structural engineers, contractors and even building owners in identifying and suggesting remedies to concrete and masonry surfaces' defects. The system identifies the kind of crack, states its most probable causes and its degree of danger, suggests a technical remedy and finally suggests several commercial names for materials to be used for curing the defect, and how to apply them. BUIL-D-EX offers complete explanations for all its questions to the users, as well as justifications for all its decisions and answers whenever needed.

title	Starting From The Micro A Pedagogical Approach to Designing Responsive Architecture
doi	https://doi.org/10.52842/conf.caadria.2003.761

summary	The paper outlines a pedagogical approach whereby a number of technology-intensive skills can be quickly learned to a level of useful practicality through a series of discrete, yet cumulative explorations with the design goal of creating intelligently responsive architectural systems. The emerging area of responsive architecture serves as a practical means for inventing entirely new ways of developing spaces, and the designing and building environments that address dynamic, flexible and constantly changing needs. Responsive architecture is defined here as spaces and objects that can physically re-configure themselves to meet changing needs. The central issues explored are human and environmental interaction and behaviors, embedded computational infrastructures, kinetic and mechanical systems and physical control mechanisms. Being both multidisciplinary and technology-intensive in nature, architects need to be equipped with at least a base foundational knowledge in a number of domains in order to be able to develop the skills necessary to explore, conceive, and design such systems. The teaching methods were carried out with a group of undergraduate design students who had no previous experience in mechanical engineering, electronics, programming, or kinetic design with the goal of creating a responsive kinetic system that can demonstrate physical interactive behaviors on an applicable architectural scale. We found the approach to be extremely successful in terms of psychologically demystifying

title	Cellular Texture Generator for Architectural Models
source	University of Texas at Arlington, Department of Computer Science and Engineering
summary	Cellular materials are used extensively in architectural settings. These materials usually have well defined geometry such as brick, stone and tiles. Patterns created with cellular materials are mostly the product of an intuitive design process that goes through cycles of synthesis and reflection until reaching final solution. Therefore interactivity is critical to intuitive designs. This paper presents a system that enables interactive creation of 3D cellular textures. It recognizes critical design areas that can have special design consideration such as edges. The system makes use of existing graphic engines and provides an intuitive interface to create patterns interactively. Rendering time is also considered through defining multiple levels of details for cells so it looks convincing in different scales. The paper presents results with an implementation of cellular texture generation system. It also shows some examples of brick walls generated with this implementation.

title	Towards a dynamic evacuation system: developing methodologies to simulate the evacuation capabilities of subway stations in response to a terrorist attack with CBRNE weapons
doi	https://doi.org/10.52842/conf.ecaade.2014.1.109
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 109-118
summary	Events in recent times have highlighted the vulnerability of underground public transportation to possible terrorist attacks. A key question therefore is how an evacuation can be accomplished from underground stations safely. The strategy “go up and take the nearest exit to the surface” might not be the best response. Evidence from the Daegu subway station fire in 2003, investigated by Tsujimoto (2003) and Jeon and Hong (2009) establish that smoke or toxic airborne substances from a terrorist attack tend to use the same direct routes used by the fleeing passengers and as result significant injuries or fatalities can occur. This study proposes the concept of a dynamic evacuation system which would guide subway users along safe routes. To test how this system may operate, the study discussed combines measurements from tracer gas experiments with climate measurements to establish how toxic agents spread in subway stations under certain conditions and combines these results with those from pedestrian simulations applied to calculate evacuation times for possible escape routes. By integrating the resulting dataset from these methods, an evidence base of how a dynamic evacuation system may work can start to form.

summary	For the majority of design practices in the construction industry the use of CAD systems have been used to merely automate hand drafting (Cohen 2003). This is the traditional way of working that has changed very little since the introduction of commercial CAD systems. These practices as means of communication are being replaced by a virtual building model environment which encapsulates all of the information for an entire construction project and thereby enables computer-supported co-operative working practices. (Newton 2003) This study aims to determine whether Building Information Modelling (BIM) can, and whether it will, replace traditional communication media as the standard in the industry for computersupported co-operative working practices in the Architecture Engineering and construction (AEC) sector. The bulk of the research comprises an extensive literature review looking at the principal reasons behind the development of BIM, the potential advantages and drawbacks of the technology, and the barriers and obstacles which inhibit its adoption as a means of computer-supported co-operative working. The findings of the study have been validated and analysed against current practice in the field through a live case study analysis of the on-going Heathrow airport Terminal 5 Project in London (UK). The Terminal 5 case study demonstrates that present software tools, although usable, still present significant implicit technical constraints to wider implementation among Small and Medium Enterprises (SMEs). The case study has also shown that in practice, the success of BIM depends just as much on the working practices and ethos of participants in the project chain as it does on the capabilities of the software itself, in particular the willingness of practitioners to change traditional working practices. The case study has shown that the present investment, in terms of time, cost, and effort required to implementing the technology means that BIM is unlikely to be adopted on small simple projects where conventional CAD is still adequate. It also highlighted that BIM tools currently available are not yet adequately developed to satisfy the requirements of the many procurement and especially contractual arrangements which presently exist and many firms will be frightened off by the unresolved legal issues which may arise from implementing BIM in their practices.

summary	Working with big models requires a good balance between the technical requirements of the model and the technical requirements of the user. Although every virtual model, whether it is 2d, 3d or 4d, may be regarded as a particular form of a general data base, it is clear that is not, at the present time, a very flexible data base. It does not behave like a relational data base that can be inspected in a flexible way. On the contrary, it has a rigid structure, a hierarchical structure that is well suited for performance but is badly suited for navigating through the data and gathering derived information. These are well known disadvantages and advantages, related to the evolution of the data base software that has moved, in the last 30 years, from a hierarchical to a relational structure. These considerations are relevant for any kind of architectural or engineering model. But are particularly pertinent in the case of the model of a city where everything must have its place, and should relate properly with other parts of the model, be susceptible of further modifications and be able to receive new information. These and other related issues have been encountered and developed during the construction of several models at our Laboratory at the ETS Architecture of Barcelona. Our paper explains the main decisions we had to take during the course of these works with special emphasis on those aspects related with the organization of different kind of data in a unified whole that had to be sent to other professionals and had to be, for that reason, organized in a clear and comprehensible way for its further development.

summary	The publicly and privately funded national R&D program ‘Digital Construction’ was initiated in 2003 in order to establish a common platform for interchanging digital information and to stimulate digital integration in the Danish building industry. This paper explores the relation between visions, strategies and tools formulated in the ‘Digital Construction’ program, and the first experiences made from implementing the 3D work method part of the program in an ongoing building project. The discussions in the paper are placed in the complex field between choosing strategies for integrating information and communication technologies on national level, and the effects of these strategies on real life building projects.
