title	Structural Composite Members in Architecture Fabricated by CAD/CAE/CAM Technology
source	Harvard University
summary	The doctoral research in this dissertation is aimed at exploring new materials and innovative methods for fabricating complex-shaped buildings, which have surfaced as a prevailing trend in architecture today. Over the past few years, the field of architecture has witnessed revolutionary changes in design. The recent completion of Frank O. Gehry's new Guggenheim Museum in Bilbao, Spain, brought unprecedented attention to complex-shaped, non-conventional designs and its influence on the global architectural trend has been immense. In following these latest trends, the author was drawn to the issues concerning construction materials and methods that are being currently adopted in realizing these complicated designs. It is perhaps inevitable that the traditional steel construction methods, suitable for use in the conventional linear shapes, face tremendous challenges and limitations in building such complex-shaped designs. In the author's opinion, the next step to go from here is to seek joint efforts between the architectural field and the engineering field to search for a new methodology which will best serve the contemporary design style. This research first focused on examining the problems that traditional methods pose for the new complex-shaped buildings. Paying attention to Gehry's recent projects, the author was able to identify major difficulties in association with representing and constructing these complicated shapes, mainly in terms of the relationship between the primary structure and the envelope surface. The second part of the research moved on to proposing a new alternative to the traditional methods, by utilizing polymer composite materials (PCM) as construction material and employing advanced Computer-Aided Design (CAD)/Computer Aided Engineering (CAE)/Computer-Aided Manufacturing (CAM) technologies. More specifically, the author has attempted to present effective theories in support of the two following ideas: (1) circular tubes made of PCM are the most promising alternative to regular steel members, especially steel tubes, to follow the envelope surface of the complex shaped building. (2) state-of-the-art CAD/CAE/CAM technologies are the most essential tools to achieve the geometrical and functional quality of the proposed new material. In the second phase, the primary focus of the quantitative approach was on fabricating an experimental model (1:1 scale prototype) called “ a unit of boundary structures”, the basic unit of structure system that wraps a complex-shaped building's entire territory .

title	Capturing Histories of Design Processes for Collaborative Building Design Development. Field Trial of the ADS Prototype
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 427-437
summary	The ADS Project - Advanced Design Support for the Construction Design Process - builds on the technological results of the previous COMMIT Project to exploit and demonstrate the benefits of a CAD based Design Decision Support System. COMMIT provides a system for storing knowledge about knowledge within the design process. It records design decisions, the actors who take them and the roles they play when doing so. ADS links COMMIT to an existing object-oriented CAD system, MicroStation/J from Bentley Systems. The project focuses on tackling the problem of managing design information without intruding too much on the design process itself. It provides the possibility to effectively link design decisions back to requirements, to gather rationale information for later stages of the building lifecycle, and to gather knowledge of rationale for later projects. The system enables members of the project team, including clients and constructors, to browse and search the recorded project history of decision making both during and after design development. ADS aims to facilitate change towards a more collaborative process in construction design, to improve the effectiveness of decision-making throughout the construction project and to provide clients with the facility to relate design outcomes to design briefs across the whole building life cycle. In this paper we will describe the field trials of the ADS prototype carried out over a three-month period at the Building Design Partnership (BDP) Manchester office. The objective of these trials is to assess the extent, to which the approach underlying ADS enhances the design process, and to gather and document the views and experiences of practitioners. The ADS prototype was previously tested with historical data of real project (Peng, Cerulli et al. 2000). To gather more valuable knowledge about how a Decision Support System like ADS can be used in practice, the testing and evaluation will be extended to a real project, while it is still ongoing. The live case study will look at some phases of the design of a mixed residential and retail development in Leeds, UK, recording project information while it is created. The users’ feedback on the system usability will inform the continuous redevelopment process that will run in parallel to the live case study. The ADS and COMMIT Projects were both funded by EPSRC.

summary	It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.

title	The Art of Spirolaterals

summary	The web site includes a series of images which is part of a larger set investigating the formation of two-dimensional designs leading to three-dimensional architectural forms using basic mathematical concepts. While investigating fractals and space curves, a mathematical figure called a "spirolateral" was encountered. A spirolateral is based on a square spiral with increasing length of turns and the turns repeating themselves. The turns can be all in one direction or certain turns can go the opposite direction. Angles other than 90 degrees can be used. The most interesting of these are ones that close on themselves, not all do. Investigating a series of possible turning angles, number of turns, number of repeats, and trying all revered turns, I identified over 10,000 spirolaterals that closed. This web site displays over 300 such spirolateral designs. In addition to investigating spirolaterals composed of straight lines, a series was developed that curves them. These designs are based on spirolaterals that are curved by antiMercator, circular, and inversion transformations. Figure 1 displays the 460 spirolateral, 4 turns at 60 degrees. Figure 2 and 3 display the same spirolateral with the antiMercator and Circular transformations applied. This web site includes galleries displaying the great variety of spirolaterals, interactive JAVA routines to display a series of spirolaterals, as well as, developing your own design, a technical description of spirolaterals, and the data for all the displayed images. My overall interest is to investigate methods that can develop forms that are in one sense predictable, but have the strong element to generate the unexpected. Using custom software enables an approach that allows variations to be investigated in a repeatable way, this enabling me to fine tune an idea by repetition and experimentation.

title	Using Evolutionary Methods for Design Case Adaptation

summary	Case-based reasoning (CBR) provides a methodology for directly using previous designs in the development of a new design. An aspect of CBR that is not well developed for designing is the combination and adaptation of previous designs. The difficulty with this aspect of case-based design is partly due to the extensive amounts of specialised knowledge needed to select the appropriate features of a previous design to include in the new design and the adaptation of these features to fit the context of a new design problem. In this paper we present a design process model that combines ideas from CBR and genetic algorithms (GA’s). The CBR paradigm provides a method for the overall process of case selection and adaptation. The GA paradigm provides a method for adapting design cases by combining and mutating their features until a set of new design requirements and constraints are satisfied. We have implemented the process model and illustrate the model for residential floor plan layout. We use a set of Frank Lloyd Wright prairie house layouts as the case base. The constraints used to determine whether new designs proposed by the process model are acceptable are taken from feng shui, the Chinese art of placement. This illustration not only clarifies how our process model for design through the evolutionary adaptation of cases works, but it also shows how knowledge sources with distinct origins can be used within the same design framework.

summary	This paper is a study of shape, attempting to understand the effect of Computer Aided Architecture Drafting and Design on the Geometry of Form. This is a part of a larger question: When the tool of presentation changes, does the form generated change as well? The study is in two main parts: 1 Comparing two Guggenheim Museums. 2 Re-Modeling Bilbao Museum. The final questions are: why does form become more complex? How do architects use tools to obtain more complexity? What Computer Aided Architecture Design programs let architects achieve more complexity? For an architect, is the motivation to demonstrate a set of 3D geometric operations sufficient to generate complex assemblies, and are there other possible operations needed?

source	Princeton, NJ: Princeton Architectural Press
summary	Frank O. Gehry, born in 1929, founded his own architectural firm in Los Angeles in 1962, and since the building of the Guggenheim Museum in Bilbao, he is undoubtedly among the ranks of international architecture superstars. His buildings are complex constructions, with curves and distortions, skilful plastic shapes which never cease to surprise with their breath-taking spatial effects. To create these daring designs, Gehry makes extensive use of the latest electronic tools, physical models are transformed into digital models using software and hardware which has been adapted from the space industry and medical research. This book provides a colourful insight into Gehry's design methods and the creative process behind his fantastic buildings.

summary	Professional design offices claim that our graduates have difficulties with their free-hand perspective drawing skills. This fact, which has become obvious over the last 5 years, is parallel to a clear tendency towards the use of 3-dimensional digital imagery in the projects of our students. Frequently, faculty tends to blame the computer for the shortcomings of our students in the use of traditional media, yet there is no clear evidence on the source of the blame. At a more fundamental level, the visualization skills of our students are questioned. This paper will explain how faculty teaching design communication techniques, with traditional and digital media, are working together in the development of a teaching methodology that makes use of computers in support of our student’s training on cognitive visualization skills, namely; “The Third-Eye Method”. The paper describes the Third-Eye Method as an alternative to traditional methods. As evidence of the benefits offered by the Third-Eye Method, the paper presents the results of testing it against traditional methods among freshman students. At the end, the paper draws as conclusion that computers are not the main source of the problem but a potential solution.

title	Spatial Orientation in Virtual Environments
source	Delft University of Technology
summary	Recently, a growing interest can be detected in the application of Virtual Environment (VE) technology as an operator interface. VEs are three-dimensional computer-generated images that can be shown on a conventional monitor, on a large screen display, or on a head-mounted display. In order to use these three-dimensional interfaces for finding and retrieving information, the user must be able to spatially orient themselves.Different types of VE technology are available for navigating in these VEs, and different types of navigation can be enabled. A choice has to be made between the different options to enable good spatial orientation of the user. There are two main types of VE interfaces: an immersive interface that provides rich sensory feedback to the user when moving around in the VE, and a non-immersive interface that provides only visual feedback to the user when moving around in the VE. Furthermore, navigation through the VE can either be continuous providing fluent motion, or can be discontinuous which means that the viewpoint is displaced instantaneously over a large distance.To provide insight into the possible effects of these options a series of nine experiments was carried out. In the experiments the quality of spatial orientation behaviour of test subjects is measured while using the different types of interface and the different types of navigation.The results of the experiments indicate that immersive navigation improves the perception of displacement through the VE, which in turn aids the acquisition of spatial knowledge. However, as soon as the spatial layout of the VE is learned the two types of navigation interface do not lead to differences in spatial orientation performance. A discontinuous displacement leads to temporary disorientation, which will hinder the acquisition of spatial knowledge. The type of discontinuous displacements has an effect on the time needed for anticipation. The disorienting effects of a discontinuous displacement can be compensated for by enabling cognitive anticipation to the destination of the displacement.These results suggest that immersive navigation might only be beneficial for application domains in which new spatial layouts have to be learned every time or in domains where the primary users are novices. For instance, in training firemen to teach them the layout of new buildings with VE, or in using architectural walkthroughs in VE to show new building designs to potential buyers. Discontinuous movement should not be allowed when exploring a new environment. Once the environment is learned and if fast displacement is essential then discontinuous displacement should be preferred. In this case, the interface designer must make sure that information is provided about the destination of a discontinuous displacement.

title	Facilitating the complexity of architectural analyses

summary	It is common practice for architecture students to collect documents on prominent buildings relevant to their design task in the early stage of design. While practitioners can rely on a body of design experience of their own, during the process of a new design, students can only draw from the examples of success and failure from other architects. In the past, such precedent based learning was implicit in the master-apprentice relationship common in the educational system. Nowadays academics commonly no longer have the possibility to maintain an extensive design practice, and instead introduce important outside precedents to the students. Thus, the study of important historical precedents or designs plays an important role in design instruction and in the students’ design processes. While there is no doubt that the most effective outcome of such a study would be achieved when the student does entire the study herself, students also benefit from a collaboration with peers, where they form groups to do an analysis of various aspects of a same building or over a group of buildings. By integrating the respective results into a common, extensible, library, students can draw upon other results for comparisons and relationships between different aspects or buildings. The complexity this introduces is best supported in a computer medium.The Web offers many examples of architectural analyses on a wide variety of subjects. Commonly, these analyses consist of a collection of documents, categorized and hyperlinked to support navigation through the information space. More sophisticated examples rely on a database for storage and management of the data, and offer a more complex categorization of the information entities and their relationships. These studies present effective ways of accessing and browsing information, however, it is precluded within these analyses to distinguish and relate different components within the project documents. If enabled, instead, this would offer a richer information structure presenting new ways of accessing, viewing, and interpreting this information. Hereto, documents can be decomposed by content. This implies both expanding the document structure, replacing document entities by detailed substructures, and augmenting the structure’s relatedness with content information. The relationships between the resulting components make the documents inherently related by content.We propose a methodology to integrate project documents into a single model, and present an application for the presentation of architectural analyses in an educational setting. This approach provides the students with a simple interface and mechanisms for the presentation of an analysis of design precedents, and possibly their own designs. Since all the information is integrated within a single environment, students will benefit from each others’ studies, and can draw new conclusions across analyses and presentations from their peers.

summary	This study looks at how interior daylighting can be understood through Web page representations. It examines how image size, sequence vs. simultaneity and interaction mode affect legibility. We formatted a set of daylighting images into different presentations using still images, animations and Quicktime Virtual Reality (QTVR). Querying architectural designers about the formats allowed us to identify usability issues, refine the alternatives, and characterize their attributes. Viewers generally preferred interactive selection of a single large image from multiple thumbnails over two or more smaller still, animated or interactive views. Smaller multiple images allow perusal of the range of lighting conditions and identification of situations for more detailed study. By rating and graphing interface, image and usability characteristics, we illustrate how photorealistic, symbolic and analytical images complement each other. We found that combining complementary representations in simultaneously or in sequence provides greatest legibility.

summary	While architects typically agree that daylight is a powerful influence for design, architects rarely collect and use daylighting data to help make informed design decisions. This deficiency exists partially because there are no common tools available to provide useful and accessible data. The objective of this project is to provide accurate daylighting data of a prominent urban building site and present it in a clear way so that the architects can make well informed design decisions that respond to site daylighting conditions and improve architectural performance. An urban 3D computer model was created with AutoCad, a commercial CAD application. Daylight was simulated with Radiance, the physically based rendering engine developed at Lawrence Berkeley National Laboratory. The standard CIE model for clear sky and sun was used to produce over 500 images that represent daylight conditions for three different times of year at 10 minute intervals in both luminance and illuminance formats. The simulation data was packaged for analysis with a unique browser tool that enables the architect to easily cycle through the data to evaluate and compare behavior by time of day and by season. The architect can also toggle between luminance and illuminance format to easily visualize both qualitative and quantitative data. The exploration and use of the simulation data can be applied with sensitivity to inform the design and decision making process for the exterior building site.

title	The Virtual Campus: A new place for (lifelong) learning?
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 472-477
doi	https://doi.org/10.52842/conf.ecaade.2002.472
summary	472 eCAADe 20 [design e-ducation] Modeling Real and Virtual Worlds Session 13 In the early spring of 2001 a collection of German universities founded a virtual faculty of architecture, which was named „Liquid Campus“. Current thinking about future forms of education in the field of architecture combined with over 4 years of experience with net-based design studios, led to questions about the future of existing universities, their buildings and their use. This problem was put to 43 students in the form of a design exercise to create a place for a virtual university. In the current situation, in which the administration of knowledge is more and more located on the internet, and even the so-called meeting places themselves can be virtualised through the help of video-conference-software, the exercise was to design a virtual campus in the framework and to carry out this design work in a simulation of distributed practice. Initial criticism of the project came from the students in that exemplary working methods were not described, but left for the students to discover on their own. The creation of a concept for the Liquid Campus meant that the participants had to imagine working in a world without the face to face contacts that form the basis (at present) of personal interaction. Additionally, the assignment to create or design possible links between the real and the virtual was not an easy task for students who normally design and plan real physical buildings. Even the tutors had difficulties in producing focused constructive criticism about a virtual campus; in effect the virtualisation of the university leads to a distinctive blurring of its boundaries. The project was conducted using the pedagogical framework of the netzentwurf.de; a relatively well established Internet based communication platform. This means that the studio was organised in the „traditional“ structure consisting of an initial 3 day workshop, a face to face midterm review, and a collective final review, held 3,5 months later in the Museum of Communication in Frankfurt am Main, Germany. In teams of 3 (with each student from a different university and a tutor located at a fourth) the students worked over the Internet to produce collaborative design solutions. The groups ended up with designs that spanned a range of solutions between real and virtual architecture. Examples of the student’s work (which is all available online) as well as their working methods are described. It must be said that the energy invested in the studio by the organisers of the virtual campus (as well as the students who took part) was considerably higher than in normal design studios and the paper seeks to look critically at the effort in relation to the outcomes achieved. The range and depth of the student’s work was surprising to many in the project, especially considering the initial hurdles (both social and technological) that had to overcome. The self-referential nature of the theme, the method and the working environment encouraged the students to take a more philosophical approach to the design problem. The paper explores the implications of the student’s conclusions on the nature of the university in general and draws conclusions specific to architectural education and the role of architecture in this process.

title	Automatic Generation of Layouts of an Utzon Housing System via the Internet
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 202-211
doi	https://doi.org/10.52842/conf.acadia.2001.202
summary	The article describes how architectural layouts can be automatically generated over the Internet. Instead of using a standard web server sending out HTML pages to browser client, the system described here uses an approach that has become common since 1998, known as three tier client/server applications. The server part of the system contains a layout generator using SPR(s), which stands for “Spatial Production Rule System, String Version”, a standard context- free string grammar. Each sentences of this language represents one valid Utzon house layout. Despite the fact that the system represents rules for laying out Utzon houses grammatically, there are important differences between SPR(s) and shape grammars. The layout generator communicates with Autocad clients by means of an application server, which is analogous to a web server. The point of this project is to demonstrate the idea that many hundreds or thousands of clients can request the generation of all of the Utzon layouts simultaneously over the Internet by the SPR(s) server, but the server never has to keep track when each client requested the generation of all of the layouts, or how many layouts each client has received.

title	Architectural design and procedural models - A radical change of language to design in architecture

summary	The history of architecture and its teaching clearly reveal how representations of the image and drawing have changed over centuries. Today, computers are increasingly found at the desks of architecture professionals and students, but their usage remains restricted to technical functions and what is commonly known as CAD (computer-assisted design), in architecture is often simply the other CAD (computer-assisted drawing).This presentation deals with architectural design, particularly at its earliest stage. Our objective is to propose a model for describing the architectural concept that meets the needs of architects through software. Only then will they really be able to use computers as an aid to design by overcoming the obstacles that presently keep us from making full use of them.This has led me to propose an avenue of exploration that examines projection through an object’s properties, and a method of computer-assisted design that makes use of procedural models. These procedural models consist of geometric operators and operators that define the properties, characteristics and performance of a building — operators which I have termed “semantic”.This research fits into a paradigm that leads to representation of the building through functions that can be called with parameters and encapsuled in an algorithm, making it possible to create procedural models that assist with the design. This approach opens up a means of integrating the logos with the figurative representation where drawing is used instead of words to convey the architectural concept.The example of a procedural model shows how we can use a generic model to produce a volume model with all the characteristics belonging to the same family of objects. This type of model can serve not only to illustrate the result of a process, or to draw connections among buildings on the basis of their construction process, or to test the validity of a rule typical of a set of objects, but also to integrate, through a functional language, semantic operators which to date have been excluded from the initial design phase. This descriptive mechanism is extremely powerful in making it possible to establish relationships among the functions and properties of a building and the purpose of the architectural project.The scientific contribution of this research is to test the hypothesis that we can use computer tools to manipulate operators which enable the architect to reappropriate a complex design of the building, and open up new lines of investigation into integrating geometric and knowledge-based systems into a unified representation. The declarative approach for creating three-dimensional scenes fits into this perspective.It is now a matter of exploring the possibility of working on a “common morphology” shared by everyone involved in the design process by rewriting the functions or by converting the functions used for representation, or else through a functional dialect (language) that allows for dialectic relationships among all types of operators and the actions of the protagonists in the architectural design process.

title	Coordinating virtual building design teams

summary	Most research in design project management support systems treats the subject as an isolated objective problem. The goals to be met are defined in terms of a supposed universal view of the project, and now outside concerns are taken into account. While such approaches, including project simulation, may yield excellent results, they ignore what, for many projects, are the real difficulties. Design projects are not isolated. All participants have other obligations that compete with the given project for attention and resources. The various participants in the design process have different goals. For these reasons it is proposed that design project management can be best facilitated by tools which assist the participating actors to share suitable management information in order to make better co-ordination possible, while allowing the resource balancing between projects to occur in private. Such a tool represents the design project management task as a negotiation task that spans both projects and firms; the management of one project is the management of all. The model of design collaboration upon which the Design Coordination System (DeCo) is built was developed from 1) a heuristic case study used to gain insight into the ways in which designers co-ordinate their efforts, and 2) the application of the theory of the social contract as developed by John Rawls to the problem of design project management. The key innovation in the DeCo system is the shaping of the project management system around existing practices of collaborative project design management and planning. DeCo takes advantage of how designers already co-ordinate their work with each other and resolve disputes over deadlines and time lines. The advantage of DeCo is that it formalises these existing practices in order to accommodate both the increasing co-ordination burden and the difficulties brought about by the internationalisation of design practice. DeCo, the design project management system proposed here, provides a representation, a communications protocol, and a game theoretical decision structure. The combination of these three units provides users with the ability to exchange structured pictures of the project as seen from the points of view of individual actors. Further, it suggests a mechanism based on a specific principle of fairness for arriving at mutually acceptable project plans. The DeCo system permits the users freedom to manage their design processes as they will, while providing a basic compatibility between practices of design team members which supports their collaborative efforts to co-ordinate their design work.

summary	The theme, which preceded my knowledge of ACADIA’s true age, resulted from a realization regarding the development and current state of CAD in Research, Education, and Practice. While I only got involved with ACADIA in the last half of its current life to date, I had the honor of studying with some of the early pioneers of CAD: 1) Harold Borkin, a founding member of ACADIA, 2) Jim Turner, a longtime ACADIAn, and a past ACADIA Conference organizer (actually the very first conference I attended), and 3) Ted Hall, another longtime ACADIAn. What I have learned from conversations with them and later witnessed for myself is a fundamental shift of focus in CAD from building tools to using tools. That is, while early CAD students, including myself, used to learn how to create software and tools to solve a particular problem, the current focus in the majority of schools that include a CAD component in their curriculum is on teaching the use of commercial software and/or the use of digital media in the design studio. One need only take a look at old list of courses that used to be offered in the CAD area and compare it with a new list to see this shift. Yet, one form of tool building that is continuing in a significant number of schools is the creation of scripts or small software modules (usually built using a visual editor) to create interactive systems for delivery over the web or on CD-ROM. Examples include the use of Macromedia Director or Flash for creating interactive digital titles. While this current state of affairs has increased the receptivity to digital tools and media, it does obscure an important fact. For knowledge to advance in this area, we need researchers who can not only use tools, but also invent new ones to solve new problems that are not addressed by the existing crop of commercial software. The more time we spend not educating our students in the art and science of building digital tools, the harder it will be to: 1) find teachers in the future with those skills, 2) advance and influence the development of the state-of-the-art in CAD, and 3) erase the use of CAD as a euphemism for slick computer-generated imagery. While not common, the tradition of tool building is still going on most notably in architecture schools with strong financial resources and those that offer doctoral level education. Commercial, governmental and business/education entities are also continuing the research tradition of tool building. ACADIA, as a reflection of the field it focuses on, has widened its scope to solicit papers that deal with CAD education and the use of CAD in practice. Thus, you will read in this book papers that focus on all three aspects: research, education, and practice and in some cases the intersection of two or more of those areas. Thankfully, ACADIA, while concerned with CAD in education has maintained its receptivity to basic research papers as well as a willingness to publish innovative papers in the area of practice. As chair of the technical committee, I made sure that the call for papers and the final selection reflects this desire. We should continue to emphasize the need for presenting this diversity of work in our annual conferences and I am optimistic that the ACADIA community is in support of this notion.

title	Web4D: Challenges and Practices for Construction Scheduling

summary	Research has demonstrated that four-dimensional computer aided design (4D CAD), in which a three-dimensional (3D) CAD model is animated through time, is useful in helping professionals understand the construction schedule. However, cumbersome processes to update a 4D CAD model, which involve changing geometry representations, changing schedules and bar charts, linking the geometry to the scheduling information, and generating animations, may discourage professionals from using 4D CAD in actual construction projects. A software prototype implementing 4D CAD in a Web environment overcomes limitations of current 4D CAD tools. This software permits editing of the construction schedule over the Internet and shows the revised construction sequence visually on a Web browser using 3D computer graphics. This software is composed of a database on a server, Active Server Pages (ASP) scripts, and a Java applet that was developed using Java 3D Application Programming Interface (API) and Java JDBC. The Java applet retrieves the 4D model at the appropriate level of completion over the Internet and allows users to navigate around the model on the Web browser. Web4D visualization software can help professionals to expedite the schedule updating process by involving designers and constructors in collaborative decision- making.

summary	Manah is an abandoned oasis settlement in Oman. During what is termed the “Golden period” in the region’s cultural development the settlement became on of the most important cultural centres of the interior. For a long period Manah stood as the seat of learning in sciences and arts. A current project is underway to establish, as far as possible, how the settlement evolved; how tribal, cultural, religious and social factors impinged on Manah as it grew over the years. The work described here is directed as applying computational methods to augment the analysis and critical review of that evolution. We are aiming to explain the evolutionary process using computer mediated techniques, working backwards from the current state, to the inception of the settlement; hence the term Digital Hindcasting.

title	Abstract but Tangible, Complex but Manageable

summary	In the VR-DIS research program, an innovative design-information modelling technique has been proposed that is based on features. In this modelling technique, the designer is invited not only to model the form and spatial aspects of his or her design, but also to model the structure of the data behind the design. The designer is offered a way to control how abstract design data is structured and stored. In this way, the designer is given the power to model concepts like conformity, contrast, and scale on the formal data level, and this for both graphical and non-graphical design characteristics. Further, the designer is invited to input formal descriptions of own design concepts, and use these personal concepts during the design process. With this new information modelling technique, we expect that the designers will be better capable to handle the complexity of linking diverse kinds of information involved in a design process. This new way of computer aided design offers a unique design freedom: any design concept becomes addressable. On the other hand, this technique also puts the responsibility for the content of the CAD database entirely in the hands of the designer. In order to be able to enjoy the design freedom fully and at the same time handle the responsibility over the design database, a computer tool is needed that shows the precise content of the database, and that is easy and quick to interact with. Only with such a tool, the designer will be capable of keeping the complex data model in pace with his or her design reasoning. To realise this requirement, a “feature browser” has been developed with a 3D graphical user interface. It shows the data objects as 3D blocks, mutually linked by rubber-band arrows that closely reflect the database structure. The whole forms an interactive 3D graph. The intuitiveness and user friendliness of the interface was improved by adding features like the visualisation of the browsing history, the visualisation of link-semantics, and animated visual feedback effects. The hardware part of the interface is worked out as a Fish Tank VR set-up. This hardware configuration improves the experienced realism of the displayed 3D objects up to a feeling of physical presence. The interface as a whole therefore provides a highly attractive display of the abstract design data; abstract but tangible. It is a tool in which complex data structures can be explored and controlled: complex but manageable.
