title	Sustaining Design Decision Makers in the AEC industry
doi	https://doi.org/10.52842/conf.caadria.2007.x.w3a

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).

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	X-House – A Game to Improve Collaboration in Architectural Design
doi	https://doi.org/10.52842/conf.ecaade.2007.141
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 141-149
summary	The current research we are conducting refers to a general model of architectural design. The complexity of the present-day design process is such that new ICT tools are required to consciously and appropriately govern the design choices. In particular, the tools that involve the early phases of the design process, when the choices crucial to the entire building process are made. In this perspective we are developing, together with a general model of architectural design based on Collaborative Design (CD), a simplified version of it – the _-House game – that can be used to help university students appreciate the complexity of doing architecture and building. This “simplified version” of the general model is therefore a useful ‘design training tool’ in the case of complex problems that can be solved by means of iterations, trade-offs, creativity, and group work; and at the same time makes it possible to highlight, define and link relatively little known aspects of design, such as scheduling, relations among operators, decision-making mechanisms, and process and design priorities.

title	Does Color Have Weaker Impact on Human Cognition Than Material?
source	Computer Aided Architectural Design Futures / 978-1-4020-6527-9 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Futures / 978-1-4020-6527-9] Sydney (Australia) 11–13 July 2007, pp. 373-384
summary	This project intends to develop a method for using virtual reality (VR) to represent a built environment for simulating environmental influences on occupants. Objectives of the project were to explore: (1) what environmental stimuli would affect habitants’ perception, and (2) what possible factors in the built environment would affect occupants’ cognition. An office was selected as the subject of study. Methods were to create a number of digital models, each containing an embedded variable, and then test the impact of environmental influences on visual perception. Results obtained in this study indicate that materials have stronger impact to human perception than colors, and VR has great potential for design decision making and post-occupancy evaluation.

title	Parametric Design and Structural Optimisation for Early Design Exploration
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 625-643
summary	The investigation presented in this paper focuses on the following questions: How can engineering and architectural expertise, assisted by a process of digital optimisation, promote structural awareness regarding design alterations in the conceptual design stages? Can building geometry be set up computationally to render it sensitive to structural input? Which software tools are required to foster this interaction and what kind of decision support is needed to allow both architects and structural engineers to interact concurrently in this optimisation process? The authors of this paper form a team of researchers and practitioners from architectural and structural engineering background who combine their efforts to address the issue of interconnecting design intelligence across disciplines and advancing revised work methodologies in practice assisted by academic research. The research has shown that an integrated transfer of design information between architectural and structural designers in the early stages is beneficial to the collaboration if experts from both professions agree on common goals and define suitability rules that guide optimisation processes from the very beginning. To enable this, software tools are required that provide ad hoc decision support to create a wider array of informed design alternatives from which to choose.

title	Temporary Housing Design and Planning Software for Disaster Relief Decision Support System
doi	https://doi.org/10.52842/conf.caadria.2007.x.k9q
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	There is a continuous and urgent need for disaster relief in Thailand and countries suffering from floods and tsunami impact. Based on this issue, design and planning software for temporary housing project has been developed, as well as the process and guideline for implementation. This paper describes a unique coupling of interactive 3D virtual environment with parametric designing in order to manage disaster relief project more efficiently. Architects and planners can use the functionality of software on both design simulation and project evaluation aspects. We need to provide correct information to help people making decision when they are in disaster. So the disaster relief decision support system must offer proper information of crisis management focused on people, place, and process. One of the main features of software is the relationship modeling of essential factors such as number of people, houses, budget, time, and space. This automatic temporary houses generation and space planning is simulated for land use and layout plan design with cost estimation analysis. The system components were proposed to a new disaster relief system in alternative approach. Using community-based development will not cost budget but required people participation. Our software’s space coordination will start and centered from available space in school or temple with sufficient infrastructure. After essential factors are inputted, appropriated number of temporary houses, public facilities, and management guideline will be generated to support further planning decision. Our core system was developed on Java and Swing Technology, empowered by real-time 3D rendering CAD engine. In addition, “Virtools” as our Authoring Tools was applied to improve design interaction and explore rapid software prototyping. At the end, we discuss the comparison between real situations in Thailand and appropriate design standardization, which should be reconsidered how to manage crisis with the limitation of time and budget from government.

title	Integration of 3D Tool with Environmental Impact Assessment (3D EIA)
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. 51-66
summary	Environmental Impact Assessment (EIA) tools have been available for some years now and their function is predominantly to predict and identify the environmental impact of building projects. However EIA analysis is often done after the completion of the project or building and when it is too late to influence the design, materials or components to be used. Also, more than 80% of the design decisions that influence the whole life cycle of a building are made at the initial design phase. EIA does not receive the required attention. A new approach is suggested in this research to ensure that designers, clients and stakeholders have all of the relevant information needed at the outline design stage for the assessment of cost and environmental impact. The idea is that building owners and users will have the opportunity to minimise their operating costs from ‘cradle to cradle’. As energy resources reduce over the next few decades, the value of this research will increase and it is possible to foresee government legislation which drives building construction in this direction. By making environmental impact analysis readily linked to 3D products at the very early stage of the design process, the value of 3D technology will be enhanced significantly resulting in more use of the technology in the construction process. In this context, the objective of this paper is to introduce and explore approaches for developing integrated 3D- EIA, LCA (Life Cycle Analysis) and LCCA (Life Cycle Cost Analysis) and VR (Virtual Reality) tools and develop trade-off analysis to assist in the decision making process. To demonstrate initial results, a pilot case study in the UK is being developed.

title	Web-based Asynchronous Design Discussion Tool with Utilities for Attaching Comments to Image Data
doi	https://doi.org/10.52842/conf.caadria.2007.x.s2x
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	In today’s global, multi-faceted society, architectural design has become a collaborative effort. Often, however, team members are separated by distance and difference in work hours. In order to keep team members connected, research groups have been developing groupware for communication and data sharing using information and communication technology. The results of recent research indicate that the systems developed are useful especially in the early phases of the architectural design process. While these systems cannot support the most important process in design collaboration— the decision making itself—they will enable team members to communicate effectively. The goal of this research is to develop a decision support groupware for the design team. As the first step, in order to enhance interaction among team members, we developed a web-based asynchronous design discussion tool named DesIBo: Design Interaction Board, such as Bulletin Board System. This paper deals with the development of DesIBo employing new concepts about entering and browsing comments and evaluating that system. In the future, we will add a decision-support function to DesIBo.

title	3 dimensional, digital, interactive, multilayered information models for enhancing decision making by two end-user groups within the Urban Planning industry: A Case Study to quantify the benefit or otherwise over alternative 2 dimensional 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. 95-110
summary	This research investigates the potential of 3 dimensional (3D), digital, interactive, multilayered information models, to enhance users’ understanding of sets of geographic and building information, allowing them to make quicker and more informed decisions, than when using alternative 2D methods. The research aims to quantify the benefit or otherwise of 3D methods of information interrogation over 2D methods by developing a test based around the decision making of two widely disparate user-groups within the Urban Planning industry. The underlying purpose of the research is to examine the human ability to interact with and understand datasets of information which are represented in the digital world. This paper specifically focuses on the methodology by which a robust test is developed to be carried out, thus proving or disproving the advantages of 3D display of information when compared to 2D. The ability to apply this same test to additional case studies in the future is a major consideration in the research design. There is a specific focus on integrating and testing a range of research instruments to best establish “language” of the industry and user groups within it, before conducting the major case study. The final research approach adopted is develop and present functional prototype models in a focus group scenario, involving hands-on interactive comparable 2D and 3D tasks, individual feedback surveys and group discussions.

title	4D Building Model - A Conceptual System of the Time Dimension in the Building’s Life
source	Vienna University of Technology; Building Science & Technology
summary	The research topic ”4D Building model: a conceptual system of the dimension of time in building’s life” is the concept of a web-based interface of a databank that stores and visualizes information of the building’s life process. It is an organization data model that brings together the serial steps of the lifetime of a building, following the design, construction and its operation time. Observing the aforementioned process as an entity, the model aims at approaching the passage of time during it, depicting the temporal relations between past, present and future steps. Visualized stored information depict the becoming of the building in time. It attempts to approach the idea of 4D architecture and explore how the dimension of time is incorporated into the model. It studies the role of information in architecture and building process observing it changing in time. The aim of this research project is to define the frame of a conceptual information system, that could develop in a plug-in by an existing design software. The model will support the design and building procedure operating as the building memory, and reporting its behaviour during its life time. In its data base, there will be reported the serial and parallel actions during the design and construction phase and additionally the reports of the monitoring evaluating system during its operational time. The final model should provide several possibilities of decision making, regarding the energy consumption, the materials life span, the costs, the participation of different firms and components.

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	This paper sets out an approach to urban modelling derived from early work with cellular automata and agglomeration models. In these cases the models are an example of distributed representation, where the rules built in to the model are replicated in all the discrete components of the model be they cells or agents. This is the classic AI. / AL paradigm of emergent systems. The paper describes the main structure of the models, and presents examples of the use of this modelling process in design education, pointing out the way dynamic models allow mapping on to interesting speculations about the dynamic of the city, and its social systems. The paper ends with a report on the use of such models as a design decision support system and how they will be used in planned work in master planning in the London Thames gateway area under the UK govt. sustainable communities initiative.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

title	Collaborative Knowledge Construction in Digital Free-Form Design
doi	https://doi.org/10.52842/conf.ecaade.2007.735
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 735-742
summary	This paper focuses on the emerging domain of digital free-form design, and attempts to explicate its knowledge content and characteristics through a systematic inquiry of the digital free-form design practice. The massive amount of information associated with the design and construction demands of the complexly shaped buildings demand explicit knowledge about the way various information pieces relate to one another. This paper reports on the process of developing a knowledge framework which serves as a reference model to describe and explain the free-form design and production processes in terms of the interaction of contextual conditions and according to the different ways design problems are perceived and formulated by the members of the design teams. The framework provides guidelines for the development of a web-based design decision support system to support collaborative knowledge construction, sharing and reuse in the domain.

summary	The existent and idle stock of buildings is extensive. However, significant information about these buildings is hardly available. The real estate owners are usually not known by prospective customers and they can be elicited only with substantial effort. But even if data about a building is available, it is difficult to valuate it precisely, because there are no standard classification techniques available, which would also consider the subjective subsequent requirements of the interested parties. The question whether a building is suitable for a certain subsequent use is therefore hard to answer. It involves an extensive expenditure of time and manpower. No reliable statement about a prospective reuse of a building can be made on site by prospective clients, i.e. buyers or renters. Therefore, we examined the technology needed by the customer to accomplish in-situ ad-hoc analyses of existing buildings. These technologies are namely remote sensing devices using georeferenced data, Location-Based Services and web-based optimization techniques. The aim is to give prospective clients the possibility to visit a building and run an in-situ usability simulation. To accomplish this, building information will be transferred between the building and the client through the use of common communication devices. These devices automatically connect to server-based applications, which compare the requirements of the prospective customer with the existing building and run remote simulations on concrete further utilization. By the use of georeferenced data alternative locations of unused buildings can be integrated into the simulation as well.

title	The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility

summary	At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

title	Spatial Simulations with Cognitive and Design Agents
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 100-114
summary	Agent based design systems could provide useful decision help for architects working on spatial planning tasks that involve large number of actors or deal with complex urban situations. These systems are especially helpful in bridging the gap between concrete design proposals and high-level design abstractions such as frequency and flow diagrams. Every attempt to use computational design agents in the planning process will automatically raise many fundamental issues about spatial perception and representation of the environment. The paper discusses these issues in the light of some recent agent based simulations. Two case studies are presented in order to demonstrate different uses of computational agents in urban design. The first study shows how a simple agent-based design system placed in an urban context becomes a creative production tool. The second one reveals analytical capabilities of an agent system in urban environments.
