title Collaborative design of structures using intelligent agents
source Automation in Construction 11 (1) (2002) pp. 89-103
summary The construction industry has a long tradition of collaborative working between the members of a construction project team. At the design stage, this has traditionally been based on physical meetings between representatives of the principal design disciplines. To aid these meetings, the information and communications technologies that are currently available have been utilised. These have yielded some success but are hampered by the problems posed by the use of heterogeneous software tools and the lack of effective collaboration tools that are necessary to collapse the time and distance constraints, within which increasingly global design teams work. In particular, there are very few tools available to support distributed asynchronous collaboration. Distributed artificial intelligence, which is commonly implemented in the form of intelligent agents, offers considerable potential for the development of such tools. This paper examines some of the issues associated with the use of distributed artificial intelligence systems within the construction industry. It describes the potential for the use of agent technology in collaborative design and then goes on to present the key features of an agent-based system for the collaborative design of portal frame structures. An example is presented to demonstrate the working and benefits of the prototype system, which makes a significant contribution by allowing for peer to peer negotiation between the design agents.

title Anticipating reuse: documenting buildings for operations using web technology
source Automation in Construction 11 (2) (2002) pp. 185-197
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; and (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 Dynamic Knowledge Map: Reusing Experts’ Tacit Knowledge in the AEC Industry
source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 407-411

summary Much knowledge in the Architecture, Engineering and Construction (AEC) industry is experience-basedand tacit. Nevertheless, the typical strategy for knowledge management is focused on computer-basedapproaches for capturing and disseminating explicit knowledge. AEC firms have been successful atcollecting and storing explicit information in enterprise databases, but they are poor at knowledgeretrieval and exchange. Consequently, AEC professionals find it difficult to reuse core experts’knowledge for highly knowledge-intensive AEC activities. This situation calls for a method fordisseminating tacit knowledge from experts’ brains to achieve higher quality AEC projects.The primary purpose of this paper is to set a theoretical foundation for clarifying the contribution ofexperts’ tacit knowledge in the AEC industry. The secondary purpose is to describe the concept forprototype software, Dynamic Knowledge Map, that can assist in the reuse of experts’ tacit knowledge.Dynamic Knowledge Map is a Web-based knowledge navigator that searches for experts and facilitatescommunication with those experts by using internet technology. Higher performance levels theoreticallycan be achieved while accelerating the knowledge transfer processes. Future research will test thesuitability of Dynamic Knowledge Map for tacit knowledge utilization in AEC organizations.

doi https://doi.org/10.52842/conf.ecaade.2023.2.801
summary This paper reconsiders the cross-disciplinary connections between music and architecture through ‘Cross-Domain Representation’ (XDR). XDR is defined as the representation of processes or artefacts from one domain within a different domain, as in the representation of music in the spatial domain. Through a case study of five drummers’ improvised responses to a piece of music, the affordances (Norman, 2002) of various methods of XDR reveal new aspects of musical performance. This case study provides an example of how cross-disciplinary practitioners may utilize the tools, methods and media of architectural design to further knowledge in the domain of music in addition to, or as a by-product of creative musico-spatial explorations.

title Towards Interoperability: ICT in Academic Curricula for Sustainable Construction
source Proceedings CIB W107 Conference: Creating a sustainable construction industry in developing countries, South Africa
summary Sustainability has been regarded as a key issue in both process and product development in industries, e.g., manufacturing, production. The construction industry has recently recognized the importance of sustainable processes in achieving overall sustainability. Demands for cheaper, faster and better products coupled with the globalisation of the economic markets are forcing the construction industry to move towards an integrated business process. In order to achieve this integration, information and knowledge sharing are considered vital to reduce waste of resources hence fostering sustainability.

Integration of process and information in a diversified, multi-disciplinary workforce like construction depends mostly on the individual’s level of expertise. Efforts at producing interoperable information standards by a growing number of alliances changing the information flow from horizontal to vertical and from sequential to cyclic. This implies that the actors in the industry must be proficient with the current and emerging Information and Communication Technologies (ICT). Recent surveys show that, there is a widening gap between required ICT skill in the workplace and those taught in academic institutions.

This paper establishes the need for ICT in construction education emphasizing interoperability as a concept among processes to achieve sustainability.

doi https://doi.org/10.52842/conf.caadria.2002.085
summary The advent of the Internet has opened up and given, particularly, the developing countries and the world in general, a transformation into collective intelligence (Levy, 1998) societies linked to digital communication (Rafi, 2001). Apart from large corporations, the rapid evolution of border-less communication has also synergise between the art and science expertise to form low-cost internet-based networks that have become multi-million dollar companies within a short period of time (e.g. Linux) (Rafi, 2001). In the context of architectural designs and construction industries, the birth of Internet-based CAD (iCAD) solutions has offered a new dimension to architectural practice. The function of CAD has expanded as a tool to communicate and collaborate as well as to better control all phases of the architectural practices. This paper will review the current available iCAD tools and explore the possible utilisation of iCAD in architectural practices. The opportunities for modifying current professional practice standards to best use iCAD will be rationalised as well as the elements in ensuring the effectiveness of iCAD implementation. The final component of the paper will be an evaluation framework to measure the value of iCAD in an architectural practice. The framework will become an early platform for an architectural practice to decide and plan their future in utilising and applying iCAD in the most efficient way.

title The Evolving Role of the Artist
source International Conference on Generative Art
summary For more than a decade the author has designed and used algorithmic systems to produce artworks that incorporate generative and evolutionary concepts, forms and processes. This work has demonstrated that algorithmic aesthetic processes and products can be effectively created and modulated by both human beings and non-human systems. However, this work has also raised important questions such as: - What role can the individual human artist play in a cultural economy based upon industrialized generative processes and non-human systems? - How can artists integrate standardized scientific languages and algorithmic processes into personal visions and expressive languages? - How can artists capture their personal creative processes and encapsulate these processes in industry standard systems and software; and should they do so? - How might the generative systems and products created by human and non-human artists function and evolve in the larger social context? To address these questions, in this paper the author uses examples taken from his past and present artwork to illustrate the opportunities and pitfalls presented by computerized generative aesthetic processes and tools. In addition, the author offers a set of conjectures intended to help clarify issues such as: the evolving role of the artist as a producer of knowledge and form, and the value and appropriate structure of personalized computer languages for artists.

title Implementation of IT and CAD - what can Architect schools do?
source AVOCAAD First International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-01-09] Brussels (Belgium) 10-12 April 1997, pp. 83-92
summary In Sweden representatives from the Construction industry have put forward a research and development program called: "IT-Bygg 2002 -Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry. A seminar was held with some of the most experienced researchers, developers and practitioners of CAD in construction in Sweden. The activities were recorded and annotated, analysed and put together afterwards; then presented to the participants to agree on. Co-operation is the key to get to the goals - IT and CAD are just the means to improve it. Co-operation in a phase of implementation is enough problematic without the technical difficulties in using computer programs created by the computer industry primarily for commercial reasons. The suggestion is that cooperation between software companies within Sweden will make a greater market to share than the sum of all individual efforts. In the short term, 2 - 5 years, implementation of CAD and IT will demand a large amount of educational efforts from all actors in the construction process. In the process of today the architect is looked upon as a natural coordinator of the design phase. In the integrated process the architect's methods and knowledge are central and must be spread to other categories of actors - what a challenge! At least in Sweden the number of researchers and educators in CAAD is easily counted. How do we make the most of it?

summary The programming languages typically offered by CAD systems for third-party application developerswere procedural or functional. A major shift is currently occurring in that new versions of commercialCAD software will support object-oriented programming languages for application development.Developers who wish to take advantage of this new kind of environment must undergo a considerablecognitive “retooling” and adopt new software engineering strategies. We describe a graduate coursethat aims at introducing students to effective object-oriented development strategies, especially usecase-driven development and the tools provided by the Unified Modeling Language (UML). Studentsgained experience with these tools by forming, together with the instructors, a single development teamwriting an application on top of MicroStation/J using JMDL as programming language. The paperdescribes the instructors’ experience with this approach.

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. 72-79
doi https://doi.org/10.52842/conf.ecaade.2002.072
summary This paper addresses an articulated vision of Virtual Reality which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client body during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. The intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared. The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running a Reality Centre. The research and teaching/learning experience in the collaborative design environment reported in this paper describe the development and application of software that aims to increase the opportunity for architects to collaborate within virtual worlds which enable effective and transparent information exchange.

summary In this project we plan to create an experimental novel medium setup for the study of the “presence” experience in shared, collective, generative, dynamic virtual environments (GENEVEs) in order to study the cross interactions between a given GENEVE and/among its creators/users and to explore the logic of presence in each GENEVE. The new shareable / generative media will try to add personal creativity and social dimension to telefruition of contents. For the European Industry having a leading edge in the technology for hw/sw/contents for shareable novel media is both a strategic asset and a social imperative.

title A design optimization tool based on a genetic algorithm
source Automation in Construction 11 (2) (2002) pp. 173-184
summary Much interest has been recently devoted to generative processes in design. Advances in computational tools for design applications, coupled with techniques from the field of artificial intelligence, have lead to new possibilities in the way computers can inform and actively interact with the design process. In this paper, we use the concepts of generative and goal-oriented design to propose a computer tool that can help the designer to generate and evaluate certain aspects of a solution towards an optimized behavior of the final configuration. This work focuses mostly on those aspects related to the environmental performance of buildings. Genetic Algorithms (GAs) are applied as a generative and search procedure to look for optimized design solutions in terms of thermal and lighting performance in a building. The GA is first used to generate possible design solutions, which are then evaluated in terms of lighting and thermal behavior using a detailed thermal analysis program (DOE2.1E). The results from the simulations are subsequently used to further guide the GA search towards finding low-energy solutions to the problem under study. Solutions can be visualized using an AutoLisp routine. The specific problem addressed in this study is the placing and sizing of windows in an office building. The same method is applicable to a wide range of design problems like the choice of construction materials, design of shading elements, or sizing of lighting and mechanical systems for buildings.

title A model for user interaction in grammar-based design systems
source Automation in Construction 11 (2) (2002) pp. 161-172
summary Grammar-based production systems are considered potentially powerful design tools by their ability to generate sets of designs adhering to user-specified constraints. However, development of such tools has been slow, partly because of the lack of good interaction between user and system. This paper describes modes of user interaction and control possible with grammar-based design systems and presents issues to be examined in the development of models that represent the locus of interactions possible with such systems. The examination of existing grammar-based systems provides empirical evidence to support the validity of such models.

title Virtual construction of architecture using 3D CAD and simulation
source Automation in Construction 11 (2) (2002) pp. 227-235
summary 3D modeling and computer simulations provide new ways for architecture students to study the relationship between the design and construction of buildings. Digital media help to integrate and expand the content of courses in drafting, construction and design. This paper describes computer-based exercises that intensify the student's experience of construction in several courses from sophomore to senior level. The courses integrate content from drafting and design communication, construction, CAD, and design. Several techniques are used to strengthen students' awareness and ability in construction. These include: Virtual design–build projects in which students construct 3D CAD models that include all elements that are used in construction. Virtual office in which several students must collaborate under the supervision of a student acting as project architect to create a 3D CAD model and design development documents. Virtual sub-contracting in which each student builds a trade specific 3D CAD model of a building and all of the trade specific models must be combined into a single model. Construction simulations (4D CAD) in which students build 3D CAD models showing all components and then animate them to illustrate the assembly process. Cost estimating using spreadsheets. These techniques are applied and reapplied at several points in the curriculum in both technical laboratory courses and design studios. This paper compares virtual construction methods to physical design–build projects and provides our pedagogical arguments for the use of digital media for understanding construction.

title Modulating Thermal Mass Behavior Through Surface Figuration

doi https://doi.org/10.52842/conf.acadia.2017.202
summary This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title Coding and modelling communication in architectural collaborative design
source Automation in Construction 11 (2) (2002) pp. 199-211
summary Although there has been some research done on collaborative face-to-face (FTF) and video-conferencing sessions involving architects, little is known about the effects these different media have on collaborative design in general and on collaborative communication and design representation in particular. In this paper, we argue that successful computer-mediated collaborative design (CMCD) does not necessarily mean emulating close-proximity environments. In order to investigate this view, we carried out experiments examining the effect and significance of different communication channels in collaborative sessions between architects. The experiments were conducted in different environments and classified into three categories. The first category is FTF. The second, CMCD sessions with full communication channels, CMCD-a. The third category was conducted also through CMCD sessions but with limited communication channels, CMCD-b. A custom coding scheme is developed using data, external and theoretically derived coding categories as a base. Examples of how the proposed coding scheme works are given from all three categories of experiments. The coding scheme provides the basis for modelling and understanding communication in collaborative design.

summary The design and construction of freeform glass roofing structures is generally accomplished through theuse of either planar triangular glass facets or curved (formed) glass panes. This paper describesongoing research on the constructability of such structures using planar quadrilateral glass facets for theJerusalem Museum of Tolerance project by Gehry Partners, in collaboration with Schlaich Bergermann& Partners, engineers. The challenge here lies not only in the development of a geometric strategy forgenerating quadrilateral planar facet solutions, but also in the fact that said solutions must closely matchthe designs created initially in physical model form by the architects.We describe a simple but robust geometric method for achieving the structure by incorporating thenecessary geometric principles into a computational parametric framework using the CATIA Version 5system. This generative system consists of a hierarchical set of geometric ‘control elements’, that drivethe design toward constructible configurations. Optimization techniques for approximating the generatedstructural shape to the original created by the designers are also described. The paper presents theunderlying geometric principles to the strategy and the resulting computational approach.

summary Considering the characteristics of highly specialized corporation in the construction industry, it's crucial to select appropriate subcontractors to implement specific subprojects. In this research, the overall subcontracting supply chain of a construction project is considered as a global procurement system and an optimal combination of subcontractors can be obtained within this system. Combining the quick response mechanism of information technology with portfolio theory in financial management, an integrated XML (eXtensible Markup Language) of Accelerated Subcontracting And Procuring (ASAP) model was proposed. The ultimate goal of this study is not only to develop a web-based decision support system for general contractors to accurately decide an appropriate trade-off between risk and profit for different combinations of subcontractors, but to take the subcontracting and procuring process into re-engineering through omnipresent Internet.

title Visual modeling and simulation for construction operations
source Automation in Construction 11 (1) (2002) pp. 47-57
summary Simulation practitioners in construction often experience difficulties in developing simulation models, i.e., tediousness and error-proneness. The visual environment presented in this paper gives users user-friendly support throughout the entire simulation development process, with the provision of a visual modeling interface, easy-to-use icon animation, and dynamic statistics. Under the visual modeling interface, modeling construction operations is completed through editing activity-based graphics as the standard graphic editing tools do, and no programming is required. An easy-to-use animation can facilitate communication between the simulation model and users, and assist users in verification and validation of the simulation model. Instead of creating 3-D images with adequate skills and much time, this animation takes the graphic simulation model as the background images and the pre-created 2-D iconic images as moving objects, in order that the preparing for animation is simple.
