title	A System for Providing Customized Housing
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. 153-166
summary	This paper describes a system for generating customized mass housing. The aim is to provide dwellings at an affordable cost with recourse to mass production and yet guarantee that they are tailored to their users. It combines two systems, a rule-based design system and a prefabricated building system. The integration of both systems is achieved through the development of a computer tool to assist designers in the various stages of the housing design process. This tool produces three kinds of outputs: three dimensional models, construction drawings, and a list of construction elements, including their cost and information for manufacturing.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	Management system for a Virtual Cooperative Project

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	Holistic Cost-Information Management in Building and Construction

summary	In the building and construction industry the need for a more holistic enterprise-overlapping information exchange is obvious. Especially the management of cost-information from the very beginning design-phase to the point of controlling and billing is a very important task. Co-operation between architects, construction companies, engineering consultants, and authorities using digital information exchange becomes a strategic success factor. Solutions which cover all stages of the value creation chain such as e-tendering, cost-estimation, cost-determination, and production must be anytime accessible and platform independent. While the basic conditions of IT-infrastructure (digital networks) are today fully sufficient, the compatibility between the systems and the information to be exchanged represent the largest problem. The main problem is in the range of different systems and various information domains. Transformations and adjustments of the exchanged information still cost nearly 40 % of design and engineering time. Efficient information exchanges require a universal exchange format, which makes the existing systems compatible. This paper describes the German approach for a holistic information exchange in the building and construction industry. Furthermore the new approach to integrate the German GAEB Standard and the Industrial Foundation Classes (IFC) and the possibilities that can be obtained out of this integration will be explained.

summary	In most design practices there is a division between the generation of information to describe buildings and the production of information to construct them. Today architects are in charge of the design of the building (aesthetics) while the contractor is accountable for the means of construction (tectonics). The advent of digital technologies within the field of architecture however has begun to cause and will continue to cause fundamental changes within the AEC industry. The Paper describes a possible scenario where a Bottom – Up, part to whole approach to architecture can be adopted using the freedom afforded by Parametric Design within the CAD-CAM environment. This approach is explored through the design of a smart block in concrete that is integrated into a wall system.

title	BIM and Integrated Practice as Provocateurs of Design Education
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.l3j
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.

title	DVIN: A Dual View Information Navigation System
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 104-109
doi	https://doi.org/10.52842/conf.acadia.2007.104
summary	Differences in the preferred modes of representation of architects and their clients create challenges to their collaboration in the design process. Traditional two-dimensional drawings such as plans, sections and elevations form the backbone of architectural representation, anchoring text labels to record relevant non-graphical information. Nominally geometric “slices” through the proposed building volume, these drawings employ abstractions and conventions unique to professional practice. In contrast, non-architects think about building configuration largely through experiential or photographic perspective. This challenge increases over the life of the project. Simple drawings, such as those used in schematic design, are easily understood by all parties. However, as the building design develops the architects encode more and more design detail through the drawing conventions of construction documents, inadvertently making this detail less and less accessible to non-architects. We present DVIN, a prototype system that uses coordinated plan and perspective views for navigation of building information models, linking the information to an individual’s spatial navigation skills rather than their document navigation skills. This web-based application was developed using Java and VRML. The prototype makes it easier for naive users to locate and query building information, whether they are a client, a facility manager, or possibly an emergency responder. * NOTE: two pages missing from the printed proceedings have been appended to the PDF version of this paper and numbered 'erratum page 1' and 'erratum page 2' *

title	From Oh-Oh to OO

doi	https://doi.org/10.52842/conf.ecaade.2007.663
summary	The architect’s profession has always been that of an organizer; a coordinator. In an increasingly specialized society such as ours there is an even greater demand for professionals with a wide range of management abilities. Today’s architect will have to organize and coordinate the flow, the means and the systematic storage of information in a project. For an institution that ‘produces’ architects, it is, in the opinion of the authors, vital to not only teach modern / contemporary methods of organizing information but also to practice them. If architecture students are to comprehend the necessity of organizing skills & tools, they will have to encounter these from day one of their student life. It is perhaps surprising (or not) that niversities are not necessarily the best example of svelte, efficient organisations. On the contrary, they are often run on age-old principles that never change, despite acknowledged faults. A faculty of architecture has been developing a system to enable all members of the faculty, (teachers and students alike), with a central service for the management of information. This service is a set of web-based tools for organizing and managing the curriculum and all matters connected to that. The objective of the platform is to increase efficiency and transparency in the administration of the faculty. The effect of the system has been to develop a community. Two main aspects buttress this community. Firstly, the users are made aware of the presence of other users through a “Who’s On Campus” module. This module allows users to see which other users are logged in and using IP Addresses and WLAN Access Point Information, where they roughly are. Secondly, through a range of communication processes, informal communication is easily undertaken with other users online. The effect has been to improve the daily activities of the faculty. Achieving this has come about not by decree, but by convincing and observable benefits from the system.

title	Mapping Design Process into Process Design: Implementing Collaborative Design from Social Psychological Approaches
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 711-716

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	A Spatial Information System for the Archaeological Site of Mycenae
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 376-394
summary	Digital and automated photogrammetric procedures, developed for the collection and management of spatial data, and terrestrial laser scanning systems provide new capabilities for documentation of archaeological monuments and sites. Also, special tools in Spatial Information Systems and production of virtual models have been developed. Their combination provides relevant scientists (architects, archaeologists, etc) and users with a variety of options for the creation of integrated systems capable for documentation, restoration and cultural development of archaeological sites. Detailed 2D and 3D representation of the current condition of the site, development of a multi-purpose SIS, and introduction of modern digital products at a local museum, such as 3D models, creation of virtual environment and Web applications are some of them. Application of such techniques and systems was made to the archaeological site of the Mycenae in Greece, one of the most important sites worldwide.

title	Temporary Housing Design and Planning Software for Disaster Relief Decision Support System
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.k9q
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	AEC Technocentrism?
source	blogspot.com
summary	Technocentrism within the AEC industry hastens digital architecture's progress and leads to low end production because advanced technology doesn't become implemented fast enough. CAD technology isn't being rolled over, expediently, to latest versions (and beyond) because complacency impedes CAD technologies from looking outside it's own discipline - obstructing access to more standardized applied systems. Post modern CAD (VDC [Virtual Design & Construction]/BIM [Building Information Modeling]) is THE system that will be the primordial digital structure to future architectures and better standardizations.

summary	Residents’ active participation is necessary for a feasible community design from the planning stage to maintenance and management. it is necessary to show information related to a plan efficiently to facilitate understanding, and to consider a plan in a limited time. The purpose of this study is to develop a Community Space Design system (CSDS) that can use GIS data and Real-time simulation, in order to support comprehension of 3D area information during continuous development. Using CSDS, participants were able to treat various GIS data fixed, and a subject called the division and the disaster prevention of a community, which the object ground is holding can be understood visually on the same 3D space as real space. Because their solution was found, the design was accepted quickly.

summary	To depict characteristics of historical buildings, digital archives must display visual information about structures and their construction. This study defines the components used for three-dimensional (3D) models of framework construction. Framework construction has heretofore portrayed structures through animation using VHS or Hi-Vision video. This paper describes a method to facilitate exhibition through interactive simulation using animation and real-time images. Furthermore, a Tablet MR can be used as an effective simulation tool for studying historical buildings in on-site models. For education about historical wooden-framework architecture, increased interactive potential according to users’ needs will be increasingly necessary.

title	The Development of an Automated Progress Measurement System for Construction Work Packages
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. 81-86
summary	The challenges associated with collecting accurate data on the progress of construction have long been recognised. Traditional methods often involve human judgment, high costs, and are too infrequent to provide managers with timely and accurate control data. The aim of this study is to propose a prototype system that employs Computer Vision (CV) techniques to report on progress for components supplied from an integrated Building Information Model (BIM). This model stores and relates this feedback to a representation of the work breakdown structure (WBS) that assigns components to work packages. In this paper we present an overview of the actual system – from the theoretical and technical challenges encountered.

title	Collaborative Knowledge Construction in Digital Free-Form Design

doi	https://doi.org/10.52842/conf.ecaade.2007.735
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.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title	Choosing Levels of Granularity in Building Information Modeling: Contractor’s Perspective

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	BIM as Learning Media for Building Construction
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007

summary	A fundamental module of any recognized architecture curricula is the understanding of buildings construction. A major component of such understanding is learning how to put together a structure system for a building. The difficulty most students find is not in knowing these structure systems in their abstract form, rather in applying this knowledge while making design decisions. Selecting the appropriate system and adapting it to the difficult conditions that accompany a particular design is the more challenging aspect to grasp. Instructors use various techniques to help students overcome this challenge. These techniques range from simply showing photos to requiring students to construct a building. This paper describes a new technique experimented with by the author. It is based on using Building Information Modeling (BIM) software as a learning media to help students face the challenge. The paper discusses the technique and the details of the experiment through a case study. The paper eventually reports on what the experiment reveals regarding the advantages and disadvantages of using BIM as a learning media.
