title	Augmented Reality-Based Education and Fire Protection for Traditional Korean Buildings
source	International Journal of Architectural Computing vol. 8 - no. 1, 75-91
summary	This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields. While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

title	Global Visualisation Engines – Issues for Urban Landscape Planning Participation Processes
source	Digital Design in Landscape Architecture 2008, Proceedings at Anhalt University of Applied Sciences, 29-31 May 2008
summary	Traditional planning processes use two-dimensional drawings, plans, sections, elevations and artists’ impressions to communicate design intent to interested parties. Three-dimensional computer visualisation technologies that support the planning process raise institutional and organisational challenges as their perceived benefits are considered. Virtual Reality (VR) models add interactivity and immersiveness to landscape visualisations but require appropriate technical input and management. This paper explores two main themes. Firstly, how interactive 3D computer simulations of planning proposals can be adopted to successfully improve the traditional process. It reports on a pilot study to examine how architects, clients, planning officers and university researchers have worked together to systematically examine and analyse this changing process. It reports on issues concerned with ownership of city models, the roles and the compatibility, accuracy and remote sharing of urban data. Secondly, we explore the emerging theme of web-based GIS applications and their impact on architectural visualisation. The process of placing urban data onto Google Earth was tested and the resulting issues emerging with this software, including IT and data management and accuracy issues for suitable architectural visualisation are discussed. The study also reports and offers an overview of placing accurate urban landscape data onto Google Earth and a discussion of using this method for online public participation and communicating technical building information.

title	Rosario, views on the integral revitalization of a cultural heritage [Rosario, Miradas sobre la Revitalización Integral de un Patrimonio Cultural]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This work shows the study of the methods and techniques for the development of a virtual vision VRML 3D included in an "Digitally-integrated knowledge base" with interactive interphases of a significantly revitalized fragment of a central area of the city of Rosario, Province of Santa Fé, Argentina, that includes an emblematic heritage for the Argentineans: the National Monument to the Flag. Digital models that partly allow the development of a hypothesis of integration between the digitized information and information technology—new digital proximity— to the effects of being able to investigate the generation of multimedia database that includes three-dimensional and dynamic models of the mentioned type, in this case, urban, architectonic, and cultural heritage. Different views and research on heritage have been developing. Nevertheless, the use of these new 3D non-immersive technologies and inter-phases are opening a new field of vision and understanding of the subject.

summary	This paper can be viewed as the continued development of a research project presented at last year’s eCAADe. The project focused on the potential and possibilities of cooperation among architects, investors with concrete building projects, and researchers at the university level working on generative design and parametric construction. After having spent several years of research on design techniques in a purely academic setting at the university we see, contrary to our fears, that reality and the integration of concrete factors such as budget, time management, etc. does not diminish but rather improves the quality of our work. This work is not primarily concerned with the development of a new architectural language but the intelligent use of modern computer technology based on digitized planning processes defined as ‘complex building design’. Designs developed in this manner can be distinguished by certain characteristics, the evaluation of which is a point critically discussed in the following paper.

title	The Role of Virtual Reality in Built Environment Education
source	Journal of Education in the Built Environment, Vol 3, Issue 1
summary	This study builds upon previous research on the integration of Virtual Reality (VR) within the built environment curriculum and aims to investigate the role of VR and three-dimensional (3D) computer modelling on learning and teaching in a school of the built environment. In order to achieve this aim, a number of academic experiences were analysed to explore the applicability and viability of 3D computer modelling and VR into built environment subject areas. Although two-dimensional (2D) representations have been greatly accepted by built environment professions and education, 3D computer representations and VR applications, offering interactivity and immersiveness, are not yet widely accepted. The study attempts to understand the values and challenges of integrating visualisation technologies into built environment teaching and investigates tutors’ perceptions, opinions and concerns with respect to these technologies. The study reports on the integration process and considers how 3D computer modelling and VR technologies can combine with, and extend, the existing range of learning and teaching methods appropriate to different disciplines and programme areas.

title	Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

title	Collaborative Financial Feasibility With CAAD For Residential Development
doi	https://doi.org/10.52842/conf.caadria.2008.594
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 594-600
summary	Computer Aided Architectural Design software is a necessary tool for the architectural design of a visible object or model. In residential development, an estimation of time/cost corresponding to the design is needed in order to complete its successful project. But available feasibility supporting tools usually lacks ability to share their information. To solve this limitation, this research proposes a design of Graphic User Interface (GUI) for collaborative financial feasibility through an architectural design process in housing project. The development of the GUI starts from collecting some information and requirement from National Housing Authority of Thailand. A heuristic decision making approach based on financial analysis are then designed for both design processes and feasibility processes of the project. Finally, design of the GUI is an integration of CAAD engines, design standards and financial feasibility analysis. Proposed GUI for collaborative financial feasibility is also tested and verified with some information from sample past projects of the National Housing Authority. From the experimental results, This GUI allows designers to improve the design of the project in real-time by inspecting the result of their design via the part of the architectural design-oriented GUI called myMonitoring and Scratch Pad. Together with planning, collaborative financial feasibility is focusing on the four main financial parameters which illustrated the possible chance of the project: Net Present Value (NPV), Benefit-Cost Ratio (B/C), Internal Rate of Return (IRR), and Payback Period. The core system was developed on Java Technology such as JSP and Swing empowered by 3D game engine. In addition, “Virtools” as an authoring tool was applied to improve interactive 3D virtual environment and explore rapid online system prototyping.

title	Reality-Informed-Design (RID); A framework for design process
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 323-328
summary	The “action” of design is an integration process, in which values, information of different kinds and data leads to a physical object of “design”. This integration process is non-linear and multiple objectives aimed, producing complex requirements to computer programs. RID systems intend to develop a new tool for the design process, using an evolving structure in the perspective to introduce basic levels of “self-awareness” in the design process to relate analogue and digital tools. This paper proposes an interpretation of the design process, a model for it and the first ideas for a possible new generation of “self awareness” design software.

summary	Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new building. A prerequisite for computer-aided planning in the context of existing buildings is both the use of on-site computer aided techniques and the integration of all professional disciplines in an integrated information and communication system. How will computers be used on site in the future? Which equipment will be needed? An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process with and within existing buildings. The aim of this project is the development of a practice-oriented toolbox for the architectural design process based on SAR (spatial augmented reality). This paper focuses on Augmented-Reality based user interaction on site using laser pointer tracking. The project is funded by the German Research Foundation.

title	Applying Scientific Simulation to Integrate Thermoelectric Conductor Module into Architectural Design – Smart Wall for Thermal Comfort
doi	https://doi.org/10.52842/conf.acadia.2005.200
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 200-210
summary	This paper presents the innovative architectural design concept, which is to integrate the new material and technology into the building design to achieve the thermal comfort and at the same time reduce the energy consumption of the building by making use of the renewable energy, including solar and wind energy. The system is developed based on the idea of regional thermal comfort in building. The advantage of the system is the environmental friendly approach, costless operation, reliability, flexibility, scalability and adaptability for the integration to the building design. With the design concept, we tried to do two application designs in two virtual sites. One is a badminton court for the 2008 Beijing Olympic Games and the other is a cooling pond in a shopping mall. We will introduce how computational simulation can contribute to the prediction of the performance of the design. We will also discuss how the computation simulation can help in the design optimization process. Through the development of the new design integration of the material to the building, we would like to feedback to the material industry to encourage further collaboration and development in the material enhancement, so that both industries and the society can benefit from the advancement.

title	From physical models to immersive collaborative environments: testing the best way for homeless people to visualise and negotiate spaces
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper describes an experiment to investigate the best way for lay people to use representation to visualise and negotiate space. It was motivated by our observations in workshops for digital inclusion in the context of a housing project for a homeless association. Computers were used to make it easier for the community to understand and change the spaces in real time. The first workshops proved that our approach was efficient as an exercise but not certainly effective concerning the understanding of spatial qualities. So we have designed an experiment to compare the usability of different media in participatory design processes. For that we have adapted the ‘Usability’ methodology, which is fully described in the paper. We started with three main questions. The first concerned the effectiveness of different media to represent spatial quality; the second concerned the best way for novices to approach space, whether by refurbishing a pre-existing space or by starting from the scratch; and the third concerned the effectiveness of negotiation by means of discourse and by means of or action. We also had two main hypothesis: one coming from research on digital environments and stereo visualisation, indicating that the more people feel immersed in the represented environment the more they are able to correlate it with physical space; and the other coming from our own observations in the participatory design workshops, in which the collective decision-making was manipulated by those people with more advanced communication skills who use their ability in an authoritative way regardless of the relevance of what they have to say. This paper describes the whole experiment, which was an exercise of spatial negotiation in 5 versions. In the first version we provided fixed digital views of a room in plan and axonometry; for another two versions we provided a physical model of the room in 1:10 scale, with some pieces of the existing furniture in different scales. This was done to check if people were just playing with a puzzle or actually grasping the correspondence between representation and the object or the space represented. One version proposes refurbishment and the other starts from the scratch. And the last two versions repeated the same task made with the physical model, but this time using a 3D interactive digital model. People were required not only to organise the furniture in the space but also to build a full scale cardboard structure and organise the real furniture reproducing their proposed model. Their comments on the spaces they had built confronted with what they had imaged when working with the model has enabled us to compare the different models, as also the different ways of negotiating spaces. This paper describes this experiment in detail concluding that 3D digital interactive models are far more effective than physical models and 2D drawings; when negotiation happens by means of action it provides more creative results than when the discoursive practice prevails; people are more creative when they start something from scratch, though they spend more time. The results of this experiment led us to formulate a new hypothesis leading to the development of an immersive collaborative environment using stereoscopy.

summary	Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

summary	Nowadays, it is becoming more and more popular for teaching and learning to be supported in technology-supported settings. These digital technologies create new instructional methods. Tangible Augmented Reality (AR) technology can construct an innovative and interactive learning space by merging computer-generated learning materials and stimuli of virtuality into a real space. Different cognitive and social-learning processes might be involved with different learning activities that can be potentially supported by different technology modes of tangible AR. This paper discusses an empirical research framework for designing and implementing tangible AR technologies to improve the pedagogical effectiveness of learning processes involved in architectural design education. The research framework includes the theoretical process of applying tangible AR in design learning, the devised experimentations and associated methodology. Issues and benefits of incorporating tangible AR into architectural design learning are also investigated and discussed.

summary	City modelling is a topic which has been on the agenda for a long time. Today crucial questions concerning the creation of a city model are resolved. The vision of the automatic generation of the 3D geometry of a city out of high resolution digital aerial images is a reality now. These new developments decreased the cost for creating and maintaining a 3D city model of a complete city significantly. This paper wants to outline the ‘history’ of 3D city models and show recent developments in this field. An overview about current applications and uses in this field in Austria and the implementation into daily work is shown with examples (Graz and Vienna city models). Additionally the new developments like Street View in Google Earth or Bird’s Eye in Virtual earth are discussed in relation to their 3D ‘relatives’.

summary	This work aims to analyze how augmented reality can be used to complement the urban cultural heritage experience with a three-dimensional model of historic building already demolished, the Monroe Palace. It analyzes possibilities and limitations of the current off-the-shelf technology of A.R. applications for architecture studies. Finally, the Layar application was used to develop a georeferenced augmented reality test with the electronic model of the building in the place where it was once built. Augmented reality was used to create a new territoriality for the lost heritage, an informational territory as defined by Lemos (2008) for a virtual heritage.

summary	Two innovations have more deeply changed the building process: the operational continuity of the design and construction phases and the software allowing not only the representation but also the autonomous creation of complex shapes never before thought, just because they could not be represented. This last innovation introduce to a “Performative Architecture” that addresses to emerge a new kind of architecture. Building performances (structural, environmental, energetic) are guiding design principles, adopting new building performance-based priorities for the design of cities, buildings and landscape. This emerging architecture places broadly defined performance above form making; It utilises digital technologies of quantitative and qualitative performance-based simulation to offer a comprehensive approach to the design of the build environment. Some aspects of “Performative Architecture” theories are critically examined and we report two experiments made using these procedures. The results try to give a contribution to detect some misunderstandings in relation to recent building projects shown.

summary	This paper reports on work carried out within the Cityware project using mobile technologies to map, visualise and project the digital co-presence in the city. This paper focuses on two pilot studies exploring the Bluetooth landscape in the city of Bath. Here we apply adapted and ‘digitally augmented’ methods for spatial observation and analysis based on established methods used extensively in the space syntax approach to urban design. We map the physical and digital flows at a macro level and observe static space use at the micro level. In addition we look at social and mobile behaviour from an individual’s point of view. We apply a method based on intervention through ‘Sensing and projecting’ Bluetooth names and digital identity in the public arena. We present early findings in terms of patterns of Bluetooth flow and presence, and outline initial observations about how people’s reaction towards the projection of their Bluetooth names practices in public. In particular we note the importance of constructing socially meaningful relations between people mediated by these technologies. We discuss initial results and outline issues raised in detail before finally describing ongoing work.

summary	The current trend in architectural design towards architectural computing has been treated both from a philosophical standing point and as an operational systems’ problem, in a quest for explications which could at last break ground for a more broad development and adoption of design tools. As Kostas Terzidis (2007) puts it, the intuitiveness that architects have put on so high a pedestal seems to be the central issue to be dealt with by both views. There seems to be no apparent shortcut toward the reconciliation between traditional practice and new media and most certainly it is not only a problem of interface design, but one of design method clarification and reinterpretation of those methods into computing systems. Furthermore, there’s no doubt left as to whether computing systems can generate such new patterns as to impact our own understanding of architecture. But even if computer algorithms can make possible the exploration of abstract alternatives to an abstract initial idea, as in Mathematica and Processing, the issue of relating abstract and geometric representations of human centered architecture lays in the hands of architects, programmers or, better yet, architect-programmers. What seems now to be the relevant change is that architectural design might escape from the traditional sequence embedded in the need – program – design iterations – solution timeline, substituted by a web of interactions among differing experimental paths, in which even the identification of needs is to be informed by computing. It is interesting to note that the computational approach to architectural design has been praised for the formal fluidity of bubbles and Bezier shapes it entails and for the overcoming of functionalist and serialization typical of modern architecture. That approach betrays a high degree of canonic fascination with the tools of the trade and very little connection to the day to day chores of building design. On the other hand, shall our new tools and toys open up new ways of thinking and designing our built landscape? What educational issues surface if we are to foster wider use of the existing technologies and simultaneously address the need to overtake mass construction? Is mass customization the answer for the dead end modern architecture has led us to? Can we let go the humanist approach begun in Renascence and culminated in Modernism or shall we review that approach in view of algorithmic architecture? Let us step back in time to 1726 when Swift’s ‘Travels into Several Remote Nations of the World by Lemuel Gulliver’ was first published. In Swift’s fierce critic of what seemed to him the most outrageous ideas, he conceived a strange machine devised to automatically write books and poetry, in much the same generative fashion that now, three centuries later, we begin to cherish. “Every one knew how laborious the usual method is of attaining to arts and sciences; whereas by his contrivance, the most ignorant person at a reasonable charge, and with a little bodily labour, may write books in philosophy, poetry, politicks, law, mathematics and theology, without the least assistance from genius or study. He then led me to the frame, about the sides whereof all his pupils stood in ranks. It was twenty foot square, placed in the middle of the room. The superficies was composed of several bits of wood, about the bigness of a dye, but some larger than others. They were all linked together by slender wires. These bits of wood were covered on every square with paper pasted on them; and, on these papers were written all the words of their language in their several moods, tenses, and declensions, but without any order. The professor then desired me to observe, for he was going to set his engine at work. The pupils at his command took each of them hold of an iron handle, whereof there were forty fixed round the edges of the frame; and giving them a sudden turn, the whole disposition of words was entirely changed. He then commanded six and thirty of the lads to read the several lines softly as they appeared upon the frame; and where they found three or four words together that might make part of a sentence, they dictated to the four remaining boys who were scribes. This work was repeated three or four times, and at every turn the engine was so contrived, that the words shifted into new places, as the square bits of wood moved upside down.” (Jonathan Swift, Gulliver’s Travels, A Voyage to Balnibarbi) What astonishing forecast did Swift show in that narrative that, in spite of the underlying incredulity and irony, still clarifies our surprise when faced to what might seem to some of us just an abandonment of all that architects and designers have cherished: creativeness and inventiveness. Yet, we could argue that such a radical shift in paradigm occurred once when master builders left the construction ground and took seat at drafting boards. The whole body of design and construction knowledge was split into what now seem to us just specialties undertaken by more and more isolated professionals. That shift entailed new forms of representation and prediction which now each and all architects take for granted. Also, Cartesian space representation turned out to be the main instrument for professional practice, even if one can argue that it is not more than the unfolding of stone carving techniques that master builders and guilds were so fond of. Enter computing and all its unfolding, i.e. DNA coding, fractal geometry, generative computing, nonlinear dynamics, pattern generation and cellular automata, as a whole new chapter in science, and compare that to conical perspective, descriptive and analytical geometry and calculus, and an image begins to form, delineating a separation between architect and digital designer. In previous works, we have tried approaching the issues regarding architects education in a more consensual way. But it seems now that the whole curricular corpus might be changed as well. The very foundations upon which we prepare future professionals shall change, not only in College, but in High School as well. In this paper, we delve further into the disconnect between current curricula and digital design practices and suggest new disciplinary grounds for a new architectural education.

summary	The modeling and simulation of pedestrian behavior has been dominantly relied on rational choice models in which pedestrians are assumed to be capable of processing a large number of choice alternatives and trade off attribute utilities. In reality, however, pedestrian behaivor shows the evidence of bounded rationality. They simplify the decision problem by considering a limited number of factors as well alternatives, using heuristics to arrive at satisfactory as opposed to optimal choices. Incorporating principles of bounded rationality in pedestrian modeling will benefit the understanding of individual decision processes and planning practice. This paper proposes an approach that models the cognitive processes such as filtering factors, constructing preference structures, deriving heterogeneous decision heuristics, and selecting decision strategies. The approach is also exemplified through estimating the model on pedestrian store patronage behavior data, collected in a shopping center in Shanghai, China. The results show the estimated probabilities of usage of decision strategies and the sequences of factor search. Compared with the conventional multinomial logit models, the results indicate the statistical advantages of the new approach.

title	Automated Cost Analysis of Concept Design BIM Models

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.
