title	Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
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.

summary	Our collective concept of computing and its relevance to architecture has undergone dramatic shifts in emphasis. A review of popular texts from the past reveals the biases and emphases that were current. In the seventies, architectural computing was generally seen as an elective for data processing specialists. In the early eighties, personal computers and commercial CAD systems were widely adopted. Architectural computing diverged from the "batch" world into the "interactive" world. As personal computing matured, introductory architectural computing courses turned away from a foundation in programming toward instruction in CAD software. By the late eighties, Graphic User Interfaces and windowing operating systems had appeared, leading to a profusion of architecturally relevant applications that needed to be addressed in introductory computing. The introduction of desktop 3D modeling in the early nineties led to increased emphasis upon rendering and animation. The past few years have added new emphases, particularly in the area of network communications, the World Wide Web and Virtual Design Studios. On the horizon are topics of electronic commerce and knowledge markets. This paper reviews these past and current trends and presents an outline for an introductory computing course that is relevant to the year 2000.

title	Digital Architecture in CAD studio and Internet-based competition
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

summary	The virtual design studio (VDS) points to a new way of practicing and teaching architectural design. As a new phenomenon, little research has been done to evaluate design collaboration and multimedia usage in a distributed workplace like the virtual design studio. Our research provides empirical data on how students actually use multiple media during architectural collaborative design.

title	A topology construction from line drawings using a uniform plane subdivision technique
source	Computer-Aided Design, Vol. 31 (5) (1999) pp. 335-348
summary	The paper describes an algorithm for constructing the topology from a set of line segments or polylines. The problem appears for example at land-maps that have been drawnby general-purpose drawing packages or captured from blue-prints by digitalisation. The solution comprises two steps; in the first step inconsistencies in the input data aredetected and removed, and in the second step the topology is constructed. The algorithm for topology construction consists of two phases: determination of a concave hull,and generation of polygons. It is shown that the running-time of the presented algorithm is better than O(n2), where n is the number of input points. Because of a largenumber of geometric elements being expected, the geometric search needed at the first step of the algorithm is speeded up by an acceleration techniquea uniform planesubdivision.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

title	Space Syntax and the New Transportation System in the Santa Catarina Island
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 434-437
summary	The paper reports an on-going research that aims at describing and analysing some of the syntactic characteristics of the urban space of Santa Catarina Island, in an attempt to evaluate its performance, more specifically its social and spatial integration and segregation. The research has been conducted with the aid of the Aximagic software, still in exam stage and not yet released to the public, a tool being developed by a group of researches of the Rio Grande do Sul Federal University and given up by Prof. Doctor Benamy Turkienicz. The software is part of a larger georeferenced program called CityZoom wich includes others tools to the comprehention of the urban morphology. This program works with graphic pictures in the inlet of data and also in the acquisition of results. The syntactic study of the Santa Catarina Island as a whole aims to obtain the comprehension of its global structure, relating it to the integrated public transportation system proposed to Florianópolis. These studies should allow an understanding of the impact the developments will have upon the urban morphology, and the new public transportation system.

title	An approach for the interoperation of web-distributed applications with a design model
source	Automation in Construction 8 (3) (1999) pp. 291-303
summary	This paper defines the data and inference requirements for the integration of analysis applications with a product model described by a CAD/CAE application. Application input conditions often require sets of complex data that may be considered views of a product model database. We introduce a method that is compatible with the STEP and PLIB product description standards to define an intermediate model that selects, extracts, and validates views of information from a product model to serve as input for an engineering CAD/CAE application. The intermediate model framework was built and tested in a software prototype, the Internet Broker for Engineering Services (IBES). The first research case for IBES integrates applications that specify certain components, for example pumps and valves, with a CAD/CAE application. This paper therefore explores a sub-set of the general problem of integrating product data semantics between various engineering applications. The IBES integration method provides support for a general set of services that effectively assist interpretation and validate information from a product model for an engineering purpose. Such methods can enable application interoperation for the automation of typical engineering tasks, such as component specification and procurement.

title	From 2D Base Map To 3D City Model
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary	Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title	Infographic: Its Incorporation and Relativity in Architectural Design Process
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 313-318
summary	This paper is about an architectural design workshop regularly held at a public university in Santa Fe, Argentina. The class is about 150 students large, with different informatic capabilities and hardware facilities. The design problem of the workshop, which is one year long, is the relationship between architectural project and the construction of the urbanity. This implies both a physical intervention and a cultural expression. Pedagogy seeks students to overcome individualism, characteristic that is hardly induced by PCs, making a socialized design experience. A complementary and simultaneous use of graphic and infographic data is one of the main criteria of the workshop. The idea is to look for students to reach a wide vision by means of the use of different representation systems and means of information. Digital graphic is introduced early in the design process as an electronic model of urban context. It is considered as a one among many other graphic resources and is used together with ordinary models, geometric drawings, aerial and regular photography and hand made sketches. This paper relates the results that have been obtained when students were asked to make an analytic and sensitive approach to the relationship site - urban situation. This relationship has a great importance for the workshop since its goal is to make students to understand the the value of designing in and for the city.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 182-185
summary	The modelization of an architectural fact, generated through a CAD program, doesn't have only the purpose of generating a virtual electronic, but a constructive scale model of geometric nature. It also implies, a conceptualization level and a posture in front of the pattern that makes thinking in other fields besides the formally constructive, such as: the descriptive and geometric patterns, the communicational and the symbolic pattern. We should understand the way the constructive thought is done the message of the model, either for the relationship with the environment and with the human scale, depends not only upon the author, but his elections will be intrinsically related with his cultural baggage, besides its geometric, graphical and technicians data. These databases condition the result of the model, for this reason we analyzed these relationships looking for a good handling of the cultural codes, to achieve a complete communication of the model. In these moments of the "global village", we should consider this problematic as a visceral topic of the architectural representation, to achieve an effective communication, among different cultures, of the models represented.

summary	The program is organized into four parts. Each is very much connected, both logically and methodologically, so that the unit as a whole consists of a content and method of access that are not divided up. This method is not in a chronological order that simply goes in one direction, rather it allows the user to "refer back", in real time and in different directions. For the simple purpose of explanation, the sections of the program are listed as follows: (-) "Basic information" concerns the basics of bioclimatic and timber architecture. Without this knowledge, the other two sections would be difficult to understand; (-) "Actual buildings throughout the world"; give examples of architectural quality; they concretize the basics of bioclimatic and timber architecture; (-) "Students' Masters Theses", that follow on from the basic information and the learning experience "in the field", and guided by the lecturer, have a critical approach to actual buildings throughout the world. (-) A multimedia data-sheet organized to ensure a clear and straightforward presentation of information about the construction products. It relies on a tab-based navigation interface that gives users access to eight different stacked windows.

summary	In 1998 I undertook an inquiry into the use of information technology in Urban Design and Planning in Danish municipalities and among planning consultants. The aim was to find out who was working with the IT and for what purposes it was used. In education there seems to be barriers to a full integration of the new media, and I wanted to find out if that was also the case in the practise of architects and planners. Surprisingly I discovered that there was a computer on almost every desk, - but there were big differences in the use of the technology. The investigation described here is based on interviews with planners in selected municipalities and with urban planning consultants, and the results have been summarised in a publication.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 700-707
summary	Our paper presents recent developments of a co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France), specialised in computer science and the HAiKZ Institute of Krakow's Faculty of Architecture, specialised in architectural heritage and conservation. Before undertaking any action to a listed building or interventions in its neighbourhood, it is vital to gain a clear understanding of the building in question. Numerous heterogeneous data detained by diverse institutions has to be handled. This process can be greatly eased by enhanced classification of the information. The development we present is a multidisciplinary platform independent information tool dedicated to education and research. SOL uses an http protocol centred computer architecture connecting a relational database, a VRML 2.0 representation module and a web search interface. It allows searches and updating of the database through a standard text based interface, a VRML 2.0 graphical module and a thematic interface. SOL is experienced on the urban fabric of the Main Square (Rynek Gówny) in Kraków. The choice of a web-centred development, both in the search and updating interface and in the representation module provides platform independence and distant access to the database, and enables successive contributions of students or researchers.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 451-457
summary	The end of the millennium with its new digital technology is contributing important tools to the area of documentation and historical patrimony those of us who support the preservation of memories think that a very important way of personalizing and strengthening our identity is to provide to those who inhabit the city with heightened awareness towards the values of our past. The revitalization requires that the patrimony in itself be valued. At the same time, it necessitates the preparation of a great amount of information utilizing cataloguing, research databases, and other materials be accessible to all citizens. This piece of work shares the different digital data base experiences that are being developed in the CEDODAL foundation art and latinamerican architecture (center for documentation), which is under the direction of the architect Ramon Gutierrez, a research services organization, and diverse higher education institutions (universities). Four bases are introduced, each with different thought and criterion structures in the definition of fields as well as in their dynamic visualizations. Each of them possesses great quantities of digital images, blue prints, and texts. In three of those bases, the data is the output from teams of researchers in different topics through special arrangements with Santa Fe's provincial water), Fonart, and city government. At the same time, the CEDODAL catalogues its documentaries with great quantities of photographic information, blue prints, research passages, and a library.

title	Parametric Urbanism: Explorations in Generative Urban Design
source	International Conference on Generative Art
summary	This paper is the result of several years of research by the Authors into the new field of generative design, as applied to urbanism. Its purpose is to formulate a concept of parametric urbanism and data-driven urban design, and how it departs from existing concepts of urban analysis and resulting design methods. This paper first gives a definition and description of the notion of generative urban design, and its relevance to current the practice of architecture and global political, sociological and economic developments. The difference between dogmatic forms of urban design and new parametric research methods is explained, and the Authors argue the fundamental relevance of using examples of post-colonial large-scale projects. In support of this, the Authors explore the widening field of research into parametric and data-driven architecture and urban design and the history of rule-based and evolutionary design methodologies. The paper illustrates examples of successful research in the field of parametric and rule-based urban design, by the Authors as well as colleagues within the field. It surveys the Authors’ work done at the Architectural Association School of Architecture, at the Hong Kong Polytechnic University School of Design, as well as in practice and research-oriented consultancy. The projects illustrated support the thesis of parametric urbanism by showing its power and versatility when applied to very large-scale projects, in particular within the People’s Republic of China.

title	Visualizacao de Informacoes Urbanas atraves de Multimidia (Visualization of Urban Information by Means of Multimedia)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 239-243
summary	Visualization is a tool that can aid understanding of phenomenon, process and spatial structures. Another important function is communication, in urban applications case, between planners, technicians, administrators, researchers and citizens. Recent technological development applied to visualization area increments analyze and interpretation capacity. The word visualization used here, is related with the use of computation for data exploration in a visual form, helping comprehension. It is a process of transformation of raw data in images, in information and visual communication. GIS and cartography precede computers. In it development GIS benefited from information technologies development and in this process emphasis goes from treatment of great amount of data to analyze of that data. Computer graphics make possible process and present visually great volume of data, thing that was not possible by conventional methods. Digital data are the key for the plain utilization of potential already available with geoprocessing technologies. Information that interest urban planners came from several sources and information technologies beside integration and manipulation permit visual analyze of spatial data in diverse aspects, from witch the most evident but not less effective a map, tool that let us correlate a great variety of qualitative and quantitative data, for organization, interpretation, presentation and communication. In digital cartographic basic elements of cartographic science were preserved, but through new products, each one execute one of the roles that traditional map plays in different ways. Database replace paper map as way of geographical information storage and cartographic visualization replaces a second role - understanding and explanation - that was satisfied by printed maps. Salvador is one of the most important brazilians metropolis. The project that we discuss have as targets construction of salvador database to permit understanding of urban space through use of thematic cartography. Several steps of project include data acquisition, database formation using data conversion and results visualization through interactive, hypermedia and thematic cartography.

title	A proposed system for integrating design and production in the precast building industry
source	The Int. Journal of Construction IT 7(1), pp. 72-83
summary	The UK construction industry is going through a major re-appraisal, with the objective of reducing construction costs by at least 30% by the end of the millennium. Precast and off-site construction are set to play a major role in improving construction productivity, reducing costs and improving working conditions. In a survey of current practices in the prefabrication industry, it was concluded that the industry is far behind other manufacturing-based industries in terms of the utilisation of IT in production planning and scheduling and other technical and managerial operations. It is suggested that a systematic, integrated, computer-aided, approach to presenting and processing information is needed. The objective of this paper is to introduce and discuss the specifications of an integrated intelligent computer-based information system for the precast concrete industry. The system should facilitate: the integration of design and manufacturing operations; automatic generation of production schedules directly from design data and factory attributes; and generation of erection schedules from site information, factory attributes and design data. It is hypothesised that the introduction of such a system would reduce the total cost of precasting by 10% and encourage clients to choose precast components more often.

summary	This article reports on the recent, geographically and temporally distributed, intercollegiate Virtual Design Studio based on the 1998 implementation Phase(x) environment. Students participating in this workshop had to create a place to wait in the form of a folly. This design task was cut in five logical parts, called phases. Every phase had to be finished within a specific timeframe (one day), after which the results would be stored in a common data repository, an online MSQL database environment which holds besides the presentations, consisting of text, 3D models and rendered images, basic project information like the descriptions of the phases and design process visualization tools. This approach to collaborative work is better known as memetic engineering and has successfully been used in several educational programs and past Virtual Design Studios. During the workshop, students made use of a variety of tools, including modeling tools (specifically Sculptor), video-conferencing software and rendering programs. The project distinguishes itself from previous Virtual Design Studios in leaving the design task more open, thereby focusing on the design process itself. From this perspective, this paper represents both a continuation of existing reports about previous Virtual Design Studios and a specific extension by the offered focus. Specific attention will be given at how the different collaborating parties dealt with the data flow and modification, the crux within a successful effort to cooperate on a common design task.

title	VRML Possibilities: The evolution of the Glasgow Model
source	Proceedings of International Conference on Virtual Systems and MultiMedia. University of Abertay. Dundee
summary	During the 1980's, ABACUS, a research unit at the University of Strathclyde developed an interest in the ability to model and manipulate large geometrical databases of urban topography. Initially, this interest lay solely in the ability to source, capture and store the relevant data. However, once constructed, these models proved genuinely useful to a wide range of users and there was soon a demand for more functionality relating to the manipulation not just of the graphics, but also the range of urban attributes. Although a number of improvements were implemented there were drawbacks to the wide adoption of the software produced. The problems were almost all due to deficiencies in the then current hardware and software system available to the professions, and although this strand of research continued to be pursued, most of the development had to be focused on research applications and deployment. However, the recent advent of the Virtual Reality Modelling Language (VRML) standards have rekindled interest in this field since this language enables many of the issues that have proved problematic in the past to be addressed and solved. The potential now exists to provide wide access to large scale urban models. This paper focuses on the application of VRML as applied to the 'Glasgow Model'.
