summary This paper focuses on an ongoing investigation exploring fabrication procedures and methodologies for robotically supported 3D printing utilising cob and other clay-based sustainable building materials, and is part of an ongoing collaboration between Cardiff University and the University of Plymouth. The methodology is that of a prototype development process within the framework of a feasibility studies call supported by the "Connected Everything: Industrial Systems in the Digital Age" EPSRC (Engineering and Physical Sciences Research Council) network. This project expects to not only reveal technological and design opportunities for 3D printed cob structures, but more broadly to engage with vernacular practice through digital means. As a result, this paper expects to contribute to the discipline by providing a framework engaging with digital practice as a way to bridge the knowledge gap between digitally-driven and vernacular modes of knowledge production, dissemination and representation.

summary As the current digitally-mediated architectural practice evolves, architectural models, regardless of their expressiveness or type, are a way to craft the interaction between the designer and the designed object. Models become artefacts that engage on a continuous interaction with the designer via different media, interpretation and knowledge retrieval schemes, organizational fl ows and tools. These interactions have recently been facilitated by the use of physical and digital production and analysis methods. In this report, we introduce a novel understanding of the relationships between physical and digital modelling techniques. We propose an updated framework that allocates these relationships into four categories: directed production, non-directed production, dual modelling, and mixed modelling. A review of different modelling classifications and frameworks is presented and exemplary case studies from the design domain are introduced for each category.

title Bridging the Gap in Constraint-Based Design
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. 133-148.
summary Mass customization is one of the most promising computational developments in the AEC industry. Despite recent advances in the production of research-based knowledge, the professional practices lack of a consistent and permanent technology adoption scheme and remain as a very resilient and fragmented industry. This work is a part of an ongoing research project developing guidelines for improving both physical and virtual modeling processes within an architectural design context. Here, we present a customizable model of a space layout explorer. The implementation of the user-driven solution-finding process is based on constraint technology embedded in Autodesk’s Revit® 2011 macros tools, commonly used in the professional practice. The aim of this work is to demonstrate a practical use of a small constraint-based system on software of widespread use. Even though there is still a lack of building information, the model has already several applications in the definition a floor plan layout and in the comparison of several instances of the design solution in the 3D user view. User-driven modifications are not made directly through the 3D model, but through different explicit text tags that describe each parameter on 2D views -although a real time 3D visualization of the model is also available-. The main findings are discussed as guidelines for further research on the end-user involvement on a ‘creative mass customization’ scheme. Also, the implementation of visual aids such as text tags during the customization process can bridge some technical obstacles for the development of interfaces for constraint-based mass customization systems. Before the final discussion, some limitations on the use of this model are described.

title Geometric Versatility of Abeille Vault - A Stereotomic Topological Interlocking Assembly
doi https://doi.org/10.52842/conf.ecaade.2016.2.391

summary The Abeille flat vault, patented at the end of 17th century, consists of identical ashlars arranged in a woven-like pattern that generates their interlocking mutual support. In recent years, the availability of digital design and fabrication tools has caused new interest in the Abeille vault. Several studies investigate the interlocking principles through their application onto non-planar assemblies. This paper is a is a more systematic exploration into the underlying geometric interdependencies behind interlocking principles. It approaches the Abeille vault as a topological interlocking assembly (TIA), an assembly where basic identical elements of a special shape are arranged in such a way that the whole structure can be held together by boundary constraint, while locally the elements are kept in place by kinematic constrains imposed through the shape and mutual arrangement of the elements. The paper looks at the full potential of the Abeille vault application and studies the relation between the surface geometry and TIA

title Rationale-Supported Mixed-Initiative Case-Based Planning
source Proceedings of IAAI-97
summary Mixed initiative planning envisions a framework in which automated and human planners interact to jointly construct plans that satisfy specific objectives. In this paper, we report on our work engineering a robust mixedinitiative planning system. Human planners rely strongly on past planning experience to generate new plans. ForMAT is a casebased system that supports human planning through the accumulation of userbuilt plans, querydriven browsing of past plans, and several plan functionality analysis primitives. Prodigy/Analogy is an automated AI planner that combines generative and casebased planning. Stored plans are annotated with plan rationale and reuse involves adaptation driven by this rationale. Our system, MICBP, integrates ForMAT and Prodigy/Analogy into a realtime messagepassing mixedinitiative planning system. The main technical approach consists of allowing the user to specify and link objectives that enable the system to capture and reuse plan rationale. We present MICBP and its concrete application to the domain of military force deployment planning. This synergistic system increases the planning efficiency of human planners through automated suggestion of similar past plans and plausible plan modifications.

title An Academy of Spatial Agents - Generating spatial configurations with deep reinforcement learning
doi https://doi.org/10.52842/conf.ecaade.2020.2.191
source Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 191-200
summary Agent-based models rely on decentralized decision making instantiated in the interactions between agents and the environment. In the context of generative design, agent-based models can enable decentralized geometric modelling, provide partial information about the generative process, and enable fine-grained interaction. However, the existing agent-based models originate from non-architectural problems and it is not straight-forward to adapt them for spatial design. To address this, we introduce a method to create custom spatial agents that can satisfy architectural requirements and support fine-grained interaction using multi-agent deep reinforcement learning (MADRL). We focus on a proof of concept where agents control spatial partitions and interact in an environment (represented as a grid) to satisfy custom goals (shape, area, adjacency, etc.). This approach uses double deep Q-network (DDQN) combined with a dynamic convolutional neural-network (DCNN). We report an experiment where trained agents generalize their knowledge to different settings, consistently explore good spatial configurations, and quickly recover from perturbations in the action selection.

title Cybernetic diagrams: design strategies for an open game
source International Journal of Architectural Computing vol. 12 - no. 4, 379-398
summary This paper investigates the use of diagrams related to cybernetics and information theory in experimental design practices in the 1960s and 1970s.Those diagrams are investigated in light of Vile_m Flusser’s concept of game, which mediates the modus operandi of computers and possible strategies for design based on distributed cognition.The research adopts the interpretative method to analyze the diagram proposed by cyberneticist Gordon Pask for Fun Palace, the diagrams produced by utopian architect Yona Friedman in the conceptual description of the Flatwriter program and Christopher Alexander’s diagrams for his theories of Synthesis of Form and Pattern Language. In the end, it establishes a brief parallel between current debates of computational design with the cybernetic diagrams, highlighting differences in their approach to complexity and design knowledge.

title Bubble2Floor: A Pedagogical Experience With Deep Learning for Floor Plan Generation
doi https://doi.org/10.52842/conf.caadria.2022.1.373
source Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 373-382
summary This paper reports a pedagogical experience that incorporates deep learning to design in the context of a recently created course at the Carnegie Mellon University School of Architecture. It analyses an exercise called Bubble2Floor (B2F), where students design floor plans for a multi-story row-house complex. The pipeline for B2F includes a parametric workflow to synthesise an image dataset with pairs of apartment floor plans and corresponding bubble diagrams, a modified Pix2Pix model that maps bubble diagrams to floor plan diagrams, and a computer vision workflow to translate images to the geometric model. In this pedagogical research, we provide a series of observations on challenges faced by students and how they customised different elements of B2F, to address their personal preferences and problem constraints of the housing complex as well as the obstacles from the computational workflow. Based on these observations, we conclude by emphasising the importance of training architects to be active agents in the creation of deep learning workflows and make them accessible for socially relevant and constrained design problems, such as housing.

title Cultura aumentada ou substituída? Distinções entre o arquiteto-ferramenta e o arquiteto-aparelho eletrônico [Culture augmented or substituted? Distinctions between the tool-architect and the robot-architect]
source SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 52-55
summary This article investigates the notion of an augmented architectural design culture elapsed of the digital revolution. Based on analytical categories proposed by the philosopher VilémFlusser it compares two systems of creative production (the tool-architect and the robot-architect), establishing new perspectives on the architectural design supported by computers. Thereafter, it identifies in the digital design agenda the overvaluation of the generative techniques over the psycho-physiological capacity of man. Lastly, the article discusses Flusser's theories to present the risks and limitations of a design practice determined by the digital techniques.

title On Slime Molds and Corridors - The application of network design algorithms to connect architectural arrangements
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 95-104
summary The use of adjacency graphs to represent and generate architectural arrangements tends to favor direct connections between contiguous rooms. These disregard specialized circulatory systems (such as corridors), which consider connections between non-contiguous spatial units or accesses. This paper addresses two specific issues: (1) how to represent a circulation network for a specific access/adjacency graph embedding; and (2) how to design good circulatory solutions for the arrangement that optimizes this network. To represent a complete circulation network, we propose a scheme, an adapted straight skeleton, based on the boundaries of the spatial units. To design possible circulation alternatives, we adopt the Slime Mold model (Tero et al., 2006; 2007). Using this model, we develop an original method, termed Adjacency Graph Selection (AGS), to generate circulation solutions for arrangements. As an initial test case for AGS, we use floor plan of the Louvre Abu Dhabi, designed by the French architect Jean Nouvel.

title Bridge Builder: An Expert System for the Design of Non-Equipment Military Bridging
source Department of Architectural Science, University of Sydney
summary This thesis describes an expert system for the selection, design and documentation of non-equipment military bridges. The expert system uses the expert system shell BUILD. Extensive use has been made of interfacing between BUILD and Prolog and then by using Prolog's foreign language interface with Pascal procedures and the graphics interface. The expert system, which consists of rules, Pascal procedures and a graphics package, aims at: (a) the determination of the suitable bridging structure; (b) designing a bridge using material constraints; (c) producing a consistent and sound structural design for the bridge and the necessary support structures; (d) producing the necessary working drawings and a bill of materials for the solution. The graphics interface is used to display and manipulate a three dimensional model of the solution and the hardcopy output. [Unpublished. -- CADLINE has abstract only.]

summary This text describes an art category which draws on the Augmented Reality (AR) Technology, which is capable of inspiring the copulation as well as the interaction, in real time, between images of reality, which might be those of the observer him/herself and the mental images, which might be artistic and generated by a computer. Stemming from the fusion of both types of image, where the former digitalises reality, whereas the latter simulates a three-dimensional image, a third image is obtained, which questions, it might be argued, reality itself. This text revolves around the attempt to demonstrate that AR is deemed a sub-group of Virtual Reality and its process as a whole as well as its imagetic system stems from the knowledge one has of the world, the exactness of reproduction one may attain of it and, finally, from the metaphor of one’s presence in it.

source Proceedings of ACM CHI 98 Conference on Human Factors in Computing Systems 1998 v.1 pp. 503-510
summary This paper describes the results of a study evaluating the effects of computer mediation on collaboratively solving architectural design problems. Pairs of graduate design students were asked to work on a landscape architecture design problem via computer terminals. In one condition they were allowed to communicate with an electronic whiteboard and a chat-line while in the other, the chat-line was substituted with video-conferencing (real-time video and audio). The protocols were evaluated according to two models. First, they were coded according to the pattern of collaboration, distinguishing meta-planning, negotiation, evaluation, and individual work. No differences were found between the two groups when coded this way. The protocols were also coded in terms of the problem-solving content, distinguishing task-related exchanges, interface-related exchanges, low-level design exchanges, and high-level design exchanges. The results showed that in the bandwidth-limited chat-line condition, participants cut down task and interface-related as well as low-level design exchanges but attempted to maintain the same amount of high-level design exchanges. When the final designs were evaluated by professional architects, no differences were found between two conditions indicating that chat-line participants implicitly compensate for the narrower bandwidth interface.

summary The use of BIM combined with Augmented Reality (AR) and Virtual Reality (VR) technologies allows the development of Virtual Design Construction (VDC). However, such application isn’t widespread in construction sites, which have their management and control performed in a traditional way. With this research, 05 applications were mapped that allow the use of BIM in conjunction with AR, listing the main uses of each application, and finally, an experiment was carried out on the use of AR on a construction site. The integration of BIM with RA makes it possible for the project manager to have the project information in loco. This context allows to collect and share construction information at the site during the building process.
