title XML for Flexibility an Extensibility of Design Information Models

summary The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title Variations on the Virtual Design Studio
source Proceedings of Computer-Supported Collaborative Work in Design
summary There are numerous approaches and techniques for setting up an environment for collaborative design. The most common approach is to extend the desktop environment to include tools for meeting and sharing files. This approach takes the individual work environment and adds tools for communicating with others. An alternative approach is to create a virtual world environment in which the collaborators meet, work, and organise their projects. This approach differs conceptually because it creates a sense of place that is unique to the project, sort of a shared office space. A variation on this approach is to create a virtual world that is the model of the product being designed. This is a more obvious choice when the product is an architectural design, but it can be extended to other kinds of design. This approach is essentially collaborating within the design. We present the three approaches and comment on their strengths and weaknesses.

summary The paper presents the findings of three years of experimentation in the use of compressed videoconferencing in international virtual design studios. Based on these findings, the authors elaborate on the development of a new videoconferencing interface: "The Infinity Room". The Infinity Room is a design studio space containing a floor-to-ceiling rear projection screen wall that conceals a dark room equipped with 5 video cameras and 4 video projectors that reproduce, on one-to-one scale, the images captured in a similar installation at a remote location. Operationally, the video cameras feed a computer that eliminate image redundancies, codes all the sources into a single entity and sends it as a compressed video signal to a remote computer that decodes and decompresses the images for synchronized delivery through the video projectors. The tiling effect of 4 synchronized and fully interactive video images creates the illusion of an adjacent room. The paper describes the design parameters used in the development of the Infinity Room and elaborates on the technology that makes it feasible. Requirements and constraints on physical space, hardware, software, and networking are discussed. The paper ends with conclusions that highlight the technical feasibility of building a small-scale prototype.

title Augmented Reality Design Decision Support Engine for the Early Building Design Stage
doi https://doi.org/10.52842/conf.caadria.2015.231
source Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 231-240
summary Augmented reality has come a long way and experienced a paradigm shift in 1999 when the ARToolKit was released as open source. The nature of interaction between the physical world and the virtual-world has changed forever. Fortunately for the AECO industry, the transition from traditional Computer Aided Design to virtual building design phrased as Building Information Modeling has created a tremendous potential to adopt Augmented Reality. The presented research is situated in the early design stage of project inception and focuses on supporting informed collective decision-making, characterized by a dynamic back and forth analytical process generating large amounts of data. Facilitation aspects, such as data-collection, storage and access to enable comparability and evaluation are crucial for collective decision-making. The current research has addressed these aspects by means of data accessibility, visualization and presentation. At the core of the project is a custom developed Augmented Reality framework that enables data interaction within the design model. In order to serve as a collaborative decision support engine, the framework also allows multiple models and their datasets to be displayed and exercised simultaneously. The paper demonstrates in the case study the successful application of the AR tool during collaborative design decision meetings.

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.

title Learning about Architecture with the Computer, and Learning about the Computer in Architecture
doi https://doi.org/10.52842/conf.ecaade.1999.374

summary Most students commencing their university studies in architecture must confront and master two new modes of thought. The first, widely known as reflection-in-action, is a continuous cycle of self-criticism and creation that produces both learning and improved work. The second, which we call here design making, is a process which considers building construction as an integral part of architectural designing. Beginning students in Australia tend to do neither very well; their largely analytic secondary education leaves the majority ill-prepared for these new forms of learning and working. Computers have both complicated and offered opportunities to improve this situation. An increasing number of entering students have significant computing skill, yet university architecture programs do little in developing such skill into sound and extensible knowledge. Computing offers new ways to engage both reflection-in-action and design making. The collaboration between two Schools in Australia described in detail here pools computer-based learning resources to provide a wider scope for the education in each institution, which we capture in the phrase: Learn to use computers in architecture (not use computers to learn architecture). The two shared learning resources are Form Making Games (Adelaide University), aimed at reflection-in-action and The Construction Primer (Deakin University and Victoria University of Wellington), aimed at design making. Through contributing to and customising the resources themselves, students learn how designing and computing relate. This paper outlines the collaborative project in detail and locates the initiative at a time when the computer seems to have become less self-consciously assimilated within the wider architectural program.

summary This paper describes a system for authoring and executing shared virtual worlds within existing VRML97 viewers such as Cosmo Player. As VRML97 does not contain any direct support for the construction of virtual worlds containing multiple users extensions are presented to provide support for shared behaviours, avatars and objects that can be manipulated and carried by participants in the world; these extensions are pre-processed into standard VRML97 and Java. A system infrastructure is described which allows worlds to be authored and executed within the context of the World Wide Web and the MBone.

source Proceedings of the focus symposium: World Wide Web as Framework for Collaboration in conjunction with the 11th International Conference on Systems Research, Informatics and Cybernetics, The International Institute for Advanced Studies in Systems Research
summary Architectural design requires specialized vertical knowledge that goes beyond the sharing of marks on paper or the multi-casting of video images. This paper briefly surveys the state-ofthe- art in groupware and outlines the need for vertical and integrated support of synchronous and asynchronous design collaboration. The paper also describes a software prototype (WebOutliner) under development that uses a three-tier persistent object-oriented, web-based technology for a richer representation of hierarchical architectural artifacts using Apple’s WebObjects technology. The prototype contributes to earlier work that defined a framework for a shared workspace consisting of Participants, Tasks, Proposals, and Artifacts. These four elements have been found through observation and analysis to be adequate representations of the essential components of collaborative architectural design. These components are also hierarchical which allows users to filter information, copy completed solutions to other parts of the program, analyze and compare design parameters and aggregate hierarchical amounts. Given its object orientation, the represented artifacts have built-in data and methods that allow them to respond to user actions and manage their own sub-artifacts. In addition, the prototype integrates this technology with Java tools for ubiquitous synchronous web-based access. The prototype uses architectural programming (defining the spatial program of a building) and early conceptual design as examples of seamlessly integrated groupware applications.

title The Future of CAAD: From Computer-aided Design to Computer-aided Collaboration
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 14-30
summary The primary uses of computers in the construction industry have been shifting, over the past four decades, from the evaluation of proposed design solutions, to their graphical (and other) representation, and more recently to facilitating collaboration among the various professionals who are involved in the design process. The paper argues that what may appear to be shifts in emphasis actually represents convergence on a single, original goal: the use of computers to help designers assess the quality, desirability, and the implications of their creations. The paper shows how the formerly independent components can be joined into an integrated collaborative design environment, where they build upon and strengthen each other. Moreover, the paper argues that this convergence represents the future of CAAD research and development, providing the appropriate answer to the upcoming needs of the construction industry, whose products have become too complex and must abide by too many requirements for any one professional to handle all by himself. The paper argues that further improvements in the overall quality of the products, and the process of their design, will only accrue when the heretofore separate solutions are considered together, as integral parts of an overall solution. The paper describes the efforts that have been made by the CAD Research Group in Berkeley over the past six years in developing an integrated collaborative design environment that can facilitate multidisciplinary, a- synchronous design of buildings. The environment includes several semantically-rich, shared product representations, a network of distributed evaluators, and graphically enhanced collaboration and negotiation tools.

summary General outline: Typology has provided architects basic design resources in the past. Repertories have been created by comparing and establishing relations among a multiplicity of examples: these repertories have been used as the basis for new inventions. Research on type establishes the foundations for organized knowledge that can be accumulated, shared, and enriched by successive designs. We are testing our assumption that CAD is a specially adequate tool for the transformation and manipulation of type in the early stages of the design process. Goals: Our Seminar/Studio gives those who take part in it a renewed vision of type as a basic disposition that can be subject to dynamic transformations. The use of CAD will allow the participants to experiment and verify design decisions on the grounds of a systematic use of typological precedents. Methodology: Starting with definite examples of contemporary architecture and the design theory backing the examples selected, the seminar/ studio is developed in eight studio sessions, exploring different dimensions leading to the “parti”. It is meant for experienced designers, both advanced students and graduates. The first experimental seminar of two sessions took place in November 1999. A more developed version is under way in August, 2000.

summary This paper is about the development of a system that supports excavation surveys by use of a PC. The system consists of two sub-systems: One is the Onsite Support System (OSS). Other is the Excavation Data Shearing System (EDSS). OSS combines a database with a general purpose CAD system. When OSS is used, it is description by excavation site and information can be managed. EDSS combines a WEB server, a database, and a VRML server. When EDSS is used, information of relic can be shared on the Internet and discussed by researchers away from the site. It provides the users with a virtual reality experience of the excavation site. The experimental system has been used as a tool by practical excavation survey of Islam city ruins from the Middle Ages in the Arab Republic of Egypt. In this paper, the framework of the system is introduced. The authors verified the effectiveness of the system by participating in an excavation survey.

title Seat preference in public squares and distribution of the surrounding people: An examination of the validity of using visual simulation

summary Public squares are shared by people who use them for various purposes. When people choose seats in a square, they unconsciously evaluate not only the physical characteristics of the space but also the distribution of others already present (Hall, 1966; Sommer, 1969; Whyte, 1988). Knowing the hidden rules of this behaviour will be important in designing squares that remain comfortable even in crowded situations. Most past studies of seat choice preference have reported on statistical tendencies derived from observations of subject behavior in actually existing sites (i.e., Abe, 1997; Imai, 1999; Kawamoto, 2003). However, they provide no clear theoretical model for explaining the basic mechanisms regulating such behaviour. The present study conducts a series of experiments in both real and virtual settings in order to extract quantitative relationships between subjects’ seat preferences and the presence of nearby strangers and to clarify what factors influence their seat choices.

NetDraw goes beyond conventional shared whiteboard applications in its support for concurrency control, groups and constraints, and ephemeral gesture objects. Small and simple enough that users can learn it quickly, NetDraw is designed to run on small platforms such as handheld computers. We describe NetDraw's features and an early evaluation of its use.

It is used to develop a pure object-oriented database server which acts as a central object repository, and facilitates the sharing of objects between multiple applications. The IBPM provided the basis for the development of the COllaborative Construction Integrated System (CO-CIS) based on the principles of client/server computing and utilising dynamic common object sharing in real-time between CAD and project management packages. The work demonstrates the capabilities of pure object technologies and should encourage industry to adopt the approach and facilitate the development of the common information standards.

summary Discussions of media in architectural design typically revolve around graphical forms, be they digital or analog. For example, much current research addresses the relationship between design sketching and cognitive process affecting the products of individual designers. This emphasis on graphics overshadows the role of text in design. While most CAD tools pursue increasingly realistic computer graphics, the interactions of designing require broader support. In this paper, we consider the importance of text in collaborative architectural design. Text is a common medium to record information in computer technology and has a role to play in an architectural design process. In the collaborative environment, a shared understanding and preserved history are important for communication. In this way, just as graphics can be seen as a cognitive aid, so too can text. Any singular design medium is insufficient to present the design idea thoroughly. Several design media should coexist. This paper outlines the cognitive background graphics in design, then reviews the role of text in design collaboration, drawing upon experimental results from cognitive science and architectural settings. As a conclusion, the paper sets out a direction for future research and development of tools to support collaborative design communication.
