summary	Efficiency and innovative problem solving are contradictory requirements for productdevelopment (PD), and both requirements must be satisfied in companies that strive to remainor to become competitive. Efficiency is strongly related to ”doing things right”, whereasinnovative problem solving and creativity is focused on ”doing the right things”.Engineering design, which is a sub-process within PD, can be viewed as problem solving or adecision-making process. New technologies in computer science and new software tools openthe way to new approaches for the solution of mechanical problems. Product datamanagement (PDM) technology and tools can enable concurrent engineering (CE) bymanaging the formal product data, the relations between the individual data objects, and theirrelation to the PD process. Many engineering activities deal with the relation betweenbehavior and shape. Modern CAD systems are highly productive tools for conceptembodiment and detailing. The finite element (FE) method is a general tool used to study thephysical behavior of objects with arbitrary shapes. Since a modern CAD technology enablesdesign modification and change, it can support the innovative dimension of engineering aswell as the verification of physical properties and behavior. Concepts and detailed solutionshave traditionally been evaluated and verified with physical testing. Numerical modeling andsimulation is in many cases a far more time efficient method than testing to verify theproperties of an artifact. Numerical modeling can also support the innovative dimension ofproblem solving by enabling parameter studies and observations of real and syntheticbehavior. Simulation-driven design is defined as a design process where decisions related tothe behavior and performance of the artifact are significantly supported by computer-basedproduct modeling and simulation.A framework for product modeling, that is based on a modern CAD system with fullyintegrated FE modeling and simulation functionality provides the engineer with tools capableof supporting a number of engineering steps in all life-cycle phases of a product. Such aconceptual framework, that is based on a moderately coupled approach to integratecommercial PDM, CAD, and FE software, is presented. An object model and a supportingmodular modeling methodology are also presented. Two industrial cases are used to illustratethe possibilities and some of the opportunities given by simulation-driven design with thepresented methodology and framework.

title	ICAtect-II: a framework for the integration of building design tools
source	Automation in Construction 8 (3) (1999) pp. 277-289
summary	The development of a system capable of integrating a range of building design tools poses many challenges. Our framework for integrating design tools provides a structured approach, allowing individual parts to be developed independently. In this paper, we describe the overall framework and suggest a method for modeling and implementing each portion of the framework. Furthermore, we illustrate how such a system can integrate several design tools and be realized as a functional design system.

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	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	Drawing, Seeing, and Reasoning: The Added Value of Computer Aided Architectural Design
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 25-33
summary	Viewing computer aided design in the context of the history of tools and media in architectural design reminds us that tools have consequences on the way of working. Design involves seeing, reasoning, and drawing in an iterative and interactive process. These three activities provide a framework for addressing the question of 'added value' in architectural design. A number of recent projects at the Sundance Lab illustrate how computer aided design can support these various activities.

title	Integrating Databases, Objects and the World-Wide Web for Collaboration in Architectural Design
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	Physical Knowledge in Patterns: Bayesian Network Models for Preliminary Design
doi	https://doi.org/10.52842/conf.ecaade.1999.611
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 611-619
summary	Computer applications in design have pursued two main development directions: analytical modelling and information technology. The former line has produced a large number of tools for reality simulation (i.e. finite element models), the latter is producing an equally large amount of advances in conceptual design support (i.e. artificial intelligence tools). Nevertheless we can trace rare interactions between computation models related to those different approaches. This lack of integration is the main reason of the difficulty of CAAD application to the preliminary stage of design, where logical and quantitative reasoning are closely related in a process that we often call 'qualitative evaluation'. This paper briefly surveys the current development of qualitative physical models applied in design and propose a general approach for modelling physical behaviour by means of Bayesian network we are employing to develop a tutoring and coaching system for natural ventilation preliminary design of halls, called VENTPad. This tool explores the possibility of modelling the causal mechanism that operate in real systems in order to allow a number of integrated logical and quantitative inference about the fluid-dynamic behaviour of an hall. This application could be an interesting connection tool between logical and analytical procedures in preliminary design aiding, able to help students or unskilled architects, both to guide them through the analysis process of numerical data (i.e. obtained with sophisticate Computational Fluid Dynamics software) or experimental data (i.e. obtained with laboratory test models) and to suggest improvements to the design.

title	Anticipating Reuse: Documenting Buildings for Operations Using Web Technology
doi	https://doi.org/10.52842/conf.acadia.1999.054
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 54-65
summary	This research explores the feasibility of Web technology as a means for delivering building information to better support facility operations. Our research proposes just-in-time (JIT) facility documentation as a pragmatic solution to the limitations of current as-built documents, allowing more effective reuse of building information. Our investigation addresses four issues: 1) what building information is needed for facility operations; 2) how the design and construction team can improve the format for delivering the building information to facility operators; 3) how current Web technology can store and deliver facility information in support of operations; 4) what is the mechanism of documenting building information using the Web technology. // We surveyed literature, interviewed members of design and operations teams and reviewed current initiatives of industry and software vendors to identify problems with current practices. We also surveyed promising Web technologies and conducted experiments to determine how these technologies could help to solve the problems. We constructed a conceptual framework of JIT facility documentation as a solution to current information fragmentation problems. We developed a prototype of the JIT document system to demonstrate a “proof of concept” by using current Web technologies such as Autodesk’s DWF, Microsoft’s Active Server Pages, VB and Java script, and Access database to develop the prototype system. By dynamically composing HTML pages in response to task-specific requests, our prototype enables easy access and integration of a variety of building information to support facility operations.

title	Integrated Computational Analysis of the Visual Environment in Buildings
source	Carnegie Mellon University, Pittsburgh
summary	Despite significant advances in the area of computational support for lighting design, lighting simulation tools have not been sufficiently integrated into the lighting design process. There is a significant body of designers who rely solely on their individual experience and do not use predictive simulation tools. Even when simulation tools are utilized, it is for design verification or presentation rather than for design support. A number of factors are thought to contribute to this lack of integration of simulation tools into the design process: a) Most existing tools rely on the problematic assumption implying the appropriateness of simplified models for the less complex early design and detailed simulation for the more complex later stages of design; b) They do not support an active exploration of design variables to satisfy desired performance criteria; c) They are not integrated with other building performance simulation models. This thesis addresses the above shortcomings by contributing to the field of visual analysis in the following areas, pertaining to the development of active, integrated design and performance simulation environments: - Implementation of a consistent and coherent, physically-based modeling approach, combining radiosity and ray-tracing methods for the simulation of light propagation. - Provision of design support both in terms of evaluation support for interpreting large amounts of computed data with diverse performance indices, and in terms of active design support to explore the relationships between the design variables and performance indices. - Integration of the lighting simulation module within a larger software environment (SEMPER) for the prediction and evaluation of multiple performance indicators (for energy, light, acoustics, etc.) in buildings.

title	Automating realization of integrated project models
source	Automation in Construction 8 (3) (1999) pp. 249-267
summary	Integration of project information has been addressed by a number of groups using a combination of product data exchange standards and centralized project models to integrate the diverse systems of different project groups. Less interest has been shown in the automation of model realization processes in such an environment. Development and use in the author's firm of an object model-based system for engineering project design and documentation has shown that considerable advantage is possible by extension of simple parametric techniques to generalized solutions, when combined with an object system optimized to support the functional aspects of realization. To automate realization processes in a collaborative environment, it is necessary to exchange sub-models that are essentially parametric, with realization processes only partially completed. We examine the requirements of and constraints on such exchange and propose a framework based on the standardization of interfaces and functional capabilities needed to support the automation of realization processes.

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.

source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 275-290
summary	The VR-DIS project aims to provide design support in the early design stage using a Virtual Reality environment. The initial brief of the design system is based on an analysis of a design case. The paper describes the process of analysis and extraction of design knowledge and design concepts in terms of Features. It is demonstrated how the analysis has lead to a classification of design concepts. This classification forms one of the main specifications for the VR-based design aid system that is being developed in the VR-DIS programme. The paper concludes by discussing the particular approach used in the case analysis and discusses future work in the VR-DIS research programme.

title	Pi-Resolution in Design Space Exploration
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 291-308
summary	In studying the phenomenon of design we use models to envision mechanisms by which computers might support design. In one such model we understand design as guided movement through a space of possibilities. Design space explorers embody this model as mixed-initiative environments in which designers engage in exploration via human computer interaction. Constraint resolution provides a formal framework for interaction in design space explorers. Rather than directly providing solutions to design problems, constraint resolution provides a mechanism for organizing construction. Therefore, we are less interested in the set of solutions to a constraint problem than the process by which intermediate steps are generated. Pi-resolution is one such mechanism applicable to design space explorers. It describes the solution, by recursive enumeration, of feature structure type constraints. During pi-resolution, satisfiers are constructed by the application of type constraints drawn from an inheritance hierarchy. This constructive process provides a strong model for design space exploration. The constraint solver does not do the work of the designer, but rather design efforts are situated in, and organized by, constraint resolution. Therefore, the efficiency of the recursive enumeration in finding solutions is not an issue, since non-determinism in the search is resolved by the human user as design space exploration.

summary	The use of the web in a didactic context appears to be extremely meaningful and effective. In Architecture, the web has huge potential: among others, it has the ability to gather an enormous amount of information, and the ability to create an active learning environment, one which affords the learner opportunities to engage and think. The paper reports on a Web Based Instruction (WBI) system developed at the Italian National Research Council -Institute for Educational and Training Technologies- to support design activities for students of the Italian Faculty of Architecture and Civil Engineering. Original features of the system allow students to study and design in an effective way. Specifically, a particular set of "virtual stationery items" has been implemented and integrated in the system to help students, enrolled on on-line courses, to mimic important traditional study activities, still gaining all the advantages of using the Web. These tools are integrated with communication tools in the same learning environment. A very important feature of the WBI system is that authorised users can enrich the information network in the system, by adding new pages and new links. In the paper we report on the structure of the system, with particular focus on the information domain. Some of the "working tools" which allow users to simulate traditional study activities and the hypertext extension mechanism are also described.

summary	New Technologies (NTs) offer us tools with which to deal with the new challenges that a changing society or workplace presents. In particular, new design strategies and approaches are required by the emerging Information Society, and NTs offer effective solutions to the designers in the different stages of their professional life, and in different working situations. In this paper some meaningful scenarios of the use of the NTs in Architecture and Urban Design are introduced; the scenarios have been selected in order to understand how the role of architects in the Information Society is changing, and what new opportunities NTs offer them. It will be underlined how the telematic networks play an essential role in the activation of virtual studios that are able to compete in an increasingly global market; examples will be given of the use of the Web to support activities related to Urban Planning and Management; it will be shown how the Internet may be used to access strategic resources for education and training, and sustain lifelong learning. The aforesaid considerations derive from a Web-Based Instruction system we have developed to support University students in the definition of projects that can concern either single buildings or whole parts of a city. The system can easily be adopted in the other scenarios introduced.

title	The right tool at the right time : investigation of freehand drawing as an interface to knowledge based design tools
source	College of Architecture, Georgia Institute of Technology
summary	Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. Given the connection between drawings and thinking, one should be able infer design intentions from a drawing and ultimately use such inferences to program a computer to understand our drawings. This dissertation reports findings from empirical studies on drawings and explores the possibility of using the computer to automatically infer designer's concerns from the drawings a designer makes. This dissertation consists of three parts: 1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; 2) empirical studies of diagramming design intentions and a design drawing experiment; and 3) the implementation of a prototype system called Right-Tool-Right-Time. The main goal is to find out what is in design drawings that a computer program should be able to recognize and support. Experiments were conducted to study the relation between drawing conventions and the design tasks with which they are associated. It was found from the experiments that designers use certain symbols and configurations when thinking about certain design concerns. When thinking about allocating objects or spaces with a required dimensions, designers wrote down numbers beside the drawing to reason xviii about size and to calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan. Based on the recognition that it is possible to associate symbols and spatial arrangements in a drawing with a designer's intention, or task context, the second goal is to find out whether a computer can be programed to recognize these drawing conventions. Given an inferred intention and context, a program should be able to activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program, and number calculations can activate a calculator. The Right- Tool-Right-Time prototype program demonstrates how a freehand sketching system that infers intentions would support the automatic activation of different design tools based on a designers' drawing acts.

summary	In the development of intelligent computer aided design systems, three important issues need to considered. These issues are: how to support the generation of product concepts using evolutionary computation techniques; how to use intelligent databases and constraint management systems for detailed exploration of product embodiment; and how to integrate rapid prototyping facilities for product evaluation. In this paper, we present a brief review of knowledge based design and evolutionary design and discuss ways of integrating both in the development of a generative design system. Based on this review, we present the model and its applications of a generative design system utilizing a number of AI and evolutionary computation techniques. This generative design model is intended to provide a generic computational framework for the development of intelligent design support systems.

summary	Current models of designing are inadequate as a basis for the development of CAAD tools for use at the conceptual stages of designing. Such models appear to be only satisfactory for the detail stages of designing. Further, current models of designing are not in accord with our present knowledge of designing. This gap has created difficulties in the development of suitable computational support tools for designers. The development of the model proposed in this paper aims to begin to fill that gap and hence provide a foundation for a new generation of computer-based design support tools, potentially applicable at the conceptual stage of designing.

summary	Considering integrated CAAD environments for architectural design, a number of different approaches are possible. This paper presents the policy of the CADLAB at the KU Leuven University, where design support right from the first design phases is a basic consideration. After a short introduction on the theoretical framework and additional design tests, we will discuss the core object model that forms the cornerstone for the contemplated design environment. This object model describes all possible data, concepts and operations connected with the architectural design process. For its development, we used the object-oriented analysis method MERODE. The starting-points and main aspects of the model will be discussed, illustrated with examples of implemented prototypes. The architect's point of view and the specific nature of the architectural design process were always kept in mind, thus leading to a model that hopes to make a valuable contribution to the research area of integrated design environments.
