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.

summary	The real estate and construction industry is among the largest industries in the world. It also is one of the most fragmented industries, with few economies of scale and historically low productivity. Recent technological advances in the use of information and communication technology have the potential for dramatically improving construction productivity. But substantial organizational barriers exist that inhibit the effective adoption of these technologies. This research project (in progress) examines the practices of selected, innovative firms in order to develop an in-depth understanding of the factors that have influenced the effective adoption of information and communications technology in the design and construction industry, and, potentially, provide examples that may provide prototype models for an alternative, future organization of the AEC industry.

title	BIM as a Viable Collaborative Working Tool: A Case Study
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007

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.

title	PROCESS INTEGRATION IN BUILDING DESIGN USING THE PARAMETER-BASED DESIGN STRUCTURE MATRIX
source	Design Studies, 27(1), pp. 99-122In B. Tuncer (Ed.), E-Activities in Building Design and Construction. (pp. 63-72). Paris: Europia
summary	This paper reviews existing process models in the Architecture-Engineering-Construction (AEC) industry and identifies two common deficiencies in them: 1. Current process models used in the industry still have a top-down approach including very little information about interrelationships at lower levels. Although these models provide a good overview of the design process, they are often too abstract to define, in detail, for complex multi-parameter problems. 2. Iteration is an important problem in collaborative design. However, most of the existing process models fail in identifying and minimizing it. With a view to alleviate these problems, this paper introduces the parameter-based Design Structure Matrix (DSM) as a tool for process integration and improvement in building design. The uses of the tool are shown via simple examples and suggestions are made for further research.

title	From CAD to iAD - A Prototype Simulation of the Internet-based Steel Construction Consulting for Architects
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 919-936
doi	https://doi.org/10.52842/conf.caadria.2003.919
summary	Information technology has become so powerful and interactive that what is conventionally called CAD might evolve into iAD (Internet Aided Design). For Internet applications in the AEC (Architecture, Engineering and Construction) industry, most of the efforts and applications have been concentrated on project management and collaboration, while in the area of design and engineering consulting, limited progress has been made. Even with some of this success, contemporary development has not changed the nature of the fragmentation of the AEC industry. Based on previous research surveys (Zhou & Krawczyk 2001) of the development of Internet applications in the AEC industry and the proposal of a conceptual model of Internet-based engineering consulting in architecture, this research will apply these theories and concepts into a specified area of steel construction consulting for architects. The first phase of this research will define the content and scope of steel construction consulting and the potential Internet application. Second, a proposed solid working model is developed covering organizational structure, user network, services provided and technology. In the third phase (as this paper presented), a prototype simulation is used to apply the concepts and methodology in a preliminary design application to demonstrate how this Internet-based consulting model would work.

summary	Globalisation and international competition force the AEC industry to change its work and collaboration practices. The traditional way of working is evolving into a more integrated process, and the traditional use of “synchronised passive” files and paperbased communication is being replaced with ICT based solutions. Currently, the AEC community is at an intermediate stage, i.e., it is shifting to “online” electronic documents. In this paper, a new concept called “eDocument” (eDoc) is introduced. The eDoc project is a cooperative effort in order to develop and implement a generic dynamically structured, multimedia, multi-channel, and multimodal information system as a means for communication in AEC projects. The major innovation in the concept is that, although it uses a repository, the focus is on the “logical and physical” specifications of the eDoc concept as a shared tele-workspace that is accessible through multiple platforms

title	Automated Generation of Residential Roomlayout within a Constrained Covered Area

summary	A significant quantum of all buildings constructed in modern times is designed for residential purpose. A tremendous amount of money is being spent every year for construction of residential buildings. Therefore, optimization of design becomes very important. In a country like India most people in urban area live in houses having constrained area. A significant part of residential units comes under mass housing either as high-rise building blocks or as plotted developments. In any of such schemes there are large number of housing units for a group of families of whom general characteristics are known but characteristics of individual families are not known at the time of designing. This situation is, however, suitable for scientific investigation and analysis based on statistical surveys. Broadly speaking, this paper suggests approach to deal with this situation of finding optimum layout of rooms of a housing unit for any target group of families when the covered area is so constrained that freedom of using different criteria like aesthetics, structural systems, materials and methods of construction in varieties of ways is drastically reduced. In such constrained area for housing units rooms are generally found rectangular within overall rectangular outline of each unit. Method shown here is valid under this restriction. It is also assumed that number of rooms will be restricted to such number that exhaustive search for design is practically possible within a reasonable time with present day capabilities of normally available PCs.

summary	The course Alternatives of Design is part of an integral viewpoint that aims to prepare architects from the Master Studies Department in Computing in Architecture (LUZ), in two ways: first, by expanding their perspective about potentialities of using new digital technologies in architecture, and second, by qualifying them to apply this acquired theoretical knowledge in their professional environment. The objectives of this paper are to describe the program of this course and to show products (2003), from the introductory to the final presentation of Virtual Museums of Interactive Sculptures, orientated and supervised both at site and at a distance through the Internet. As a result of this experience, a sample was obtained of virtual museums. design and modelling that illustrates what could be understood as virtual architecture with high degree of interaction, looking for the evolution, motivation and teamwork to incorporate virtual reality non-inmersive technologies in this new architectonic approach.

summary	This paper describes the concept and the current state of development of a new laboratory for digital experimentation in architectural education and research. The novel forms of collaboration and learning for which it is intended and the quick pace of innovation in digital technology on which it depends both require an appropriately flexible spatial and technological framework. And it requires a particular mindset. The no_LAb__in_feld is not just another laboratory. It is a place, a community, a high-tech construction site, a permanent work in progress. It is the prototype of a next generation design studio.

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.

title	Space, Place and Digital Media:Towards a Better Simulation of a City that has now Disappeared
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Digital media enable researchers and designers to derive better informed processes in solving problems of historical architectural restoration and virtual archaeology. However, recently insufficiencies have been found in the main technologies often applied in such techniques, such as 3D modeling, high-quality rendering and animation. Given these problems, this paper attempts to explore a digital reconstruction procedure for historical architecture and cities using 3D scanning, Virtual Reality cave technology and motion capture technology. This case study is based on a collaborative project in conjunction with the National Palace Museum, Taiwan, and the China Times, Taiwan.The five steps involved in this project include data collection and analysis, three-dimensional digital inferences, digital reconstruction of static and moving models, scenario dynamics (by integrating the two kinds of models), and visual-spatial immersion using a VR-cave representation. Finally, a preliminary digital reconstruction procedure is presented.

title	Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title	Real Teaching and Learning through Virtual Reality
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	This paper addresses an articulated vision of Virtual Reality, which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client bodies during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. A key intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared.The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for the creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running in a Reality Centre.

title	Supporting Communication Processes for Cooperative Planning and e-Government
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Abstract: As a reaction to societal, economic and technological changes, new forms of cooperation are applied in projects of urbanand regional development. We argue that this trend can significantly be amplified by the use of information and communicationtechnologies (ICT). Through ICT more persons can participate in a more focused, open, fairer and more transparent way. Complexinformation can be analyzed, the process is documented, reproducible and comparable. Methods and media can be combined in avery flexible way to design efficient and effective processes.To the extent that projects are stored in a knowledge base, knowledge management tools can exploit accumulating experience tocontinuously improve a methodology for cooperation in spatial development.With the introduction of ICT, existing cooperative methods in government and planning should not simply be copied to the newmedia without further modifications. Electronic techniques (synchronous or asynchronous, distributed or not, audio-, video or textbasedmedia) can be used for different traditional methods in different phases of the process, and they can be combined in completelynew ways, leading to new methods and workflows. Only if this potential of ICT is taken into account by restructuring the processitself, cooperative planning processes lead to informed high-quality decisions in less time.Our approach aims to explore the opportunities that new ICT offers for new cooperation methods in government and planning –beyond the extension of traditional methods to electronic communication media. It acknowledges the need for experimentation andan evaluation, not only concerning isolated methods but the combination of methods.

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	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.

summary	This paper explores a method for the use of rapid prototyping devices to physically construct details of Palladio’s unbuilt villas designs. The goal of the paper is to create clear identities of the rules used to physically build any villa. Results will provide rule instructions for the assembly of components for the physical construction of the 23 villa designs found in The Four Books of Architecture.
