title	Hierarchical Decomposition of Architectural Computer Models
doi	https://doi.org/10.52842/conf.caadria.1997.197
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 197-203
summary	Architectural models can be represented in a hierarchy of complexity. Higher level or more complex architecture structures are then designed by repetitively instantiating libraries of building blocks. The advantages are that the object can be achieved in modular fashion and any modification to the definition of a building block can be easily propagated to all higher level objects using the block. Unfortunately, many existing representations of architectural models are monolithic instead of hierarchical and modular, thus, making the reuse of models very difficult and inefficient. This paper describes a research project on developing a tool to decompose a monolithic architectural model into elementary building blocks and then create a hierarchy in the model representation. The tool provides a graphical interface for the visualization of a model and a cutting plane. An associated algorithm will then automatically detach parts of the model into building blocks depending on where the user is applying the cutting plane. Studies will also be made on dividing more complex models employing spherical and NURBS surfaces.

title	Punching Above Your Weight: Digital Design Methods and Organisational Change in Small Practice
doi	https://doi.org/10.52842/conf.acadia.2007.040
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 40-47
summary	Expanding bodies of knowledge imply expanding teams to manage this knowledge. Paradoxically, it can be shown that in situations of complexity—which increasingly characterise the production of architecture generally—the small practice or small team could be at an advantage. This is due to the increasingly digital nature of the work undertaken and artefacts produced by practices, enabling production processes to be augmented with digital toolsets and for tight project delivery networks to be forged with other collaborators and consultants (Frazer 2006). Furthermore, as Christensen argues, being small may also be desirable, as innovations are less likely to be developed by large, established companies (Christensen 1997). By working smarter, and managing the complexity of design and construction, not only can the small practice “punch above its weight” and compete with larger practices, this research suggests it is a more appropriate model for practice in the digital age. This paper demonstrates this through the implementation of emerging technologies and strategies including generative and parametric design, digital fabrication, and digital construction. These strategies have been employed on a number of built and un-built case-study projects in a unique collaboration between RMIT University’s SIAL lab and the award-winning design practice BKK Architects.

title	A Software for Automatically Verifying Compatibility in Complicated Building Assemblies
doi	https://doi.org/10.52842/conf.ecaade.1997.x.q4q
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The research we are carrying on is intended to develop a tool aiding to design building mechanical assembly systems, which are often characterised by high complexity levels. In fact, when designing complicated building assemblies by making use of common graphical representations, it might be impossible for the operator to choose the proper shape and installation sequence of components so that they do not interfere during the assembly, and to check, in the meantime, the most favorable setting up modalities according to execution problems. Our software, running within CAD, by starting from the definition of the node features, will allow the operator to automatically get three types of representation that can simulate the assembly according to the assigned installation sequence: - instant images of the phases for setting up each component into the node; - 3D views showing the position of each component disassembled from the node and indicating the movements required for connection; - the components moving while the node is being constructed. All the representations can be updated step by step each time modifications to the node are made. Through this digital iterative design process - that takes advantage of various simultaneous and realistic prefigurations - the shape and function compatibility between the elements during the assembling can be verified. Furthermore, the software can quickly check whether any change and integration to the node is efficacious, rising the approximation levels in the design phase. At the moment we have developed the part of the tool that simulates the assembly by moving the components into the nodes according to the installation sequence.

title	Computer Visualization as a Tool for the Conceptual Understanding of Architecture
doi	https://doi.org/10.52842/conf.acadia.1997.243
source	Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 243-248
summary	A good piece of architecture contains many levels of interrelated complexity. Understanding these levels and their interrelationship is critical to the understanding of a building to both architects and non-architects alike. A building's form, function, structure, materials, and details all relate to and impact one another. By selectively dissecting and taking apart buildings through their representations, one can carefully examine and understand the interrelationship of these building components. With the recent introduction of computer graphics, much attention has been given to the representation of architecture. Floor plans and elevations have remained relatively unchanged, while digital animation and photorealistic renderings have become exciting new means of representation. A problem with the majority of this work and especially photorealistic rendering is that it represents the building as a image and concentrates on how a building looks as opposed to how it works. Often times this "look" is artificial, expressing the incapacity of programs (or their users) to represent the complexities of materials, lighting, and perspective. By using digital representation in a descriptive, less realistic way, one can explore the rich complexities and interrelationships of architecture. Instead of representing architecture as a finished product, it is possible to represent the ideas and concepts of the project.

title	Working with unpredictability
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper deals with notions of complexity in art and architecture. On the basis of a recent sculptural work by Richard Serra, Torqued Ellipses (1997), the notion of complexity is investigated in terms of how it situates the viewer, and affects our sense of space and time. Serra’s work is analyzed in terms of the artist’s working method, the production of the work, and finally the ”external relations” which connect it to the viewer and the context. In each of these steps, the notions of complexity and unpredictability are shown to have a formative role. The relations between space and time, object and context, are redefined in Serra’s work, which also gives it great importance for architectural theory and practice.

title	An Advanced Groupware Approach for an Integrated Planning Process in Building Construction
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 475-480
summary	Increasing complexity of today's buildings requires a high level of integration in the planning process. Common planning strategies, where individual project partners cooperate mainly to exchange results, are not suitable to jointly develop project goals and objectives. Integrated planning, a more holistic approach to deal with complex problems, is based on a high degree of communication among team members and leads to a goal oriented cooperation. This paper focuses on the application of an advanced groupware approach suitable to support efficiently an integrated design process in construction. First an appropriate planning process model will be presented, which differs from common product model approaches and takes into account the great importance of team- and goal orientation in integrated planning. Then the idea of an open CSCW platform is proposed, which basic structure and containing elements are based on the defined planning model. Appropriate cooperative planning scenarios can then be ad-hoc modeled and configured dynamically on this CSCW platform according to the requirements of the specific project. For the participants of the planning process, the resulting groupware approach represents an integrated computer based working environment. This environment allows a kind of immersion into the project. Finally a prototypical implementation of this approach will be shortly discussed.

title	Computer-Aided Design and Manufacturing of Complex Shaped Concrete Formwork
source	Doctor of Design Thesis, Graduate School of Design, Harvard University, Cambridge, MA
summary	The research presented in this thesis challenges the appropriateness of existing, conventional forming practices in the building construction industry--both in situ or in prefabrication--for building concrete "freeforms," as they are characterized by impracticality and limitations in achieved geometric/formal quality. The author's theory proposes the application of alternative, non-traditional construction methods derived from the integration of information technology, in the form of Computer-Aided Design (CAD), Engineering (CAE) and Manufacturing (CAM), into the concrete tooling and placing process. This concept relies on a descriptive shape model of a physically non-existent building element which serves as a central database containing all the geometric data necessary to completely and accurately inform design development activities as well as the construction process. For this purpose, the thesis orients itself on existing, functioning models in manufacturing engineering and explores the broad spectrum of computer-aided manufacturing techniques applied in this industry. A two-phase, combined method study is applied to support the theory. Part I introduces the phenomenon of "complexity" in the architectural field, defines the goal of the thesis research and gives examples of complex shape. It also presents the two analyzed technologies: concrete tooling and automation technology. For both, it establishes terminology, classifications, gives insight into the state-of-the-art, and describes limitations. For concrete tooling it develops a set of quality criteria. Part II develops a theory in the form of a series of proposed "non-traditional" forming processes and concepts that are derived through a synthesis of state-of-the-art automation with current concrete forming and placing techniques, and describes them in varying depth, in both text and graphics, on the basis of their geometric versatility and their appropriateness for the proposed task. Emphasis is given to the newly emerging and most promising Solid Freeform Fabrication processes, and within this area, to laser-curing technology. The feasibility of using computer-aided formwork design, and computer-aided formwork fabrication in today's standard building practices is evaluated for this particular technology on the basis of case-studies. Performance in the categories of process, material, product, lead time and economy is analyzed over the complete tooling cycle and is compared to the performance of existing, conventional forming systems for steel, wood, plywood veneer and glassfiber reinforced plastic; value s added to the construction process and/or to the formwork product through information technology are pointed out and become part of the evaluation. For this purpose, an analytical framework was developed for testing the performance of various Solid Freeform Fabrication processes as well as the "sensitivity," or the impact of various influencing processes and/or product parameters on lead time and economy. This tool allows us to make various suggestions for optimization as well as to formulate recommendations and guidelines for the implementation of this technology. The primary objective of this research is to offer architects and engineers unprecedented independence from planar, orthogonal building geometry, in the realization of design ideas and/or design requirements for concrete structures and/or their components. The interplay between process-oriented design and innovative implementation technology may ultimately lead to an architecture conceived on a different level of complexity, with an extended form-vocabulary and of high quality.

title	Characteristics of existing construction automation and robotics technologies
source	Automation in Construction 6 (2) (1997) pp. 109-120
summary	As a first step in detailed assessment, this research analyzes selected attributes of 85 existing construction automation and robotics technologies to examine certain trends in the development of construction technologies and the attributes of the technologies which can influence their use by construction companies. In general, previously identified priorities for automation are close to being fulfilled, and correspond with opportunities for adoption. Most of the technologies concentrate on areas of identified benefits, and attempt to reduce the complexity associated with adoption through only minimal changes in tasks. In the same way, complementary changes required to use the technologies are kept at a minimum overall. This analysis is used to identify further opportunities for the development and implementation of construction automation and robotics technologies.

title	Edge of Chaos. Towards intelligent architecture through distributed control systems based on Cellular Automata.
doi	https://doi.org/10.52842/conf.acadia.2018.226

summary	From the “Edge of Chaos”, a mathematical space discovered by computer scientist Christopher Langton (1997), compelling behaviors originate that exhibit both degrees of organization and instability creating a continuous dance between order and chaos. This paper presents a project intended to make this complex theory tangible through an interactive installation based on metamaterial research which demonstrates emergent behavior using Cellular Automata (CA) techniques, illustrated through sound, light and motion. We present a multi-sensory narrative approach that encourages playful exploration and contemplation on perhaps the biggest questions of how life could emerge from the disorder of the universe. We argue a way of creating intelligent architecture, not through classical Artificial Intelligence (AI), but rather through Artificial Life (ALife), embracing the aesthetic emergent possibilities that can spontaneously arise from this approach. In order to make these ideas of emergent life more tangible we present this paper in four integrated parts, namely: narrative, material, hardware and computation. The Edge of Chaos installation is an explicit realization of creating emergent systems and translating them into an architectural design. Our results demonstrate the effectiveness of a custom CA for maximizing aesthetic impact while minimizing the live time of architectural kinetic elements.

title	The development of IT-supported residential services: a conceptual model of influences and constraints
source	Automation in Construction 6 (5-6) (1997) pp. 499-510
summary	An understanding of the potential and the complexity of IT-supported residential services is essential in order to realize it, especially if one will foresee some of its implications, such as constraints by and influences on the institutions, the markets and the power structure in society. Since our society appears to us as mainly artificial, the creation of IT-supported residential services can be seen as a matter of design. Design in that sense to study how things ought to be and not how they are. The paper describes a conceptual model, and the methodology behind it, of the complex domain of IT-supported service infrastructures for residential living. The model indicates how the residents and the institutions, such as the municipalities, the housing companies, the service providers and the IT-industry, will sanction, prevent or modify the market of residential services.

title	An Integrated Computing Environment for Collaborative, Multi-Disciplinary Building Design
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 389-416
summary	The increasing complexity of the built environment requires that more knowledge and experience be brought to bear on its design, construction and maintenance. The commensurate growth of knowledge in the participating disciplines-architecture, engineering, construction management, facilities management, and others-has tended to diversify each one into many sub-specializations. The resulting fragmentation of the design-built-use process is potentially detrimental to the overall quality of built environment. An efficient system of collaboration between all the specialist participants is needed to offset the effects of fragmentation. It is here that computers, with their ubiquitous presence in all disciplines, can serve as a medium of communication and form the basis of a collaborative, multi- disciplinary design environment. This paper describes the ongoing research on the development of such an integrated computing environment that will provide the basis for design and evaluation tools ranging across the many building-related disciplines. The bulk of the discussion will focus on the problem of a building representation that can be shared by all these disciplines, which, we posit, lies at the core of such an environment. We discuss the criteria that characterize this shared building representation, and present our solution to the problem. The proposed model has been adapted from geometric modeling, and addresses explicitly the difficult Problem of generality versus completeness of the represented information. The other components of the integrated environment that are under development are also described. The paper concludes with some implementation details and a brief look at two evaluation tools that use the proposed building representation for their task.

title	Exploratory investigation of solid freeform construction
source	Automation in Construction 5 (5) (1997) pp. 427-437
summary	A radical departure from generally accepted concepts in construction robotics is proposed in this paper. A new process derived from the emerging field of additive manufacturing processes is investigated for its potential effectiveness in construction automation. In essence, complex assemblies of large construction components are substituted with a large number of elemental component assemblies. The massive complexity of information processing required in construction is replaced with a large number of simple elemental operations which lend themselves easily to computer control. This exploratory work is illustrated with sample masonry structures that cannot be obtained by casting. They are manufactured by an incremental deposition of sand and Portland cement akin to Navajo sand painting. A thin layer of sand is deposited, followed by the deposition of a patterned layer of cement. Steam is then applied to the layer to obtain rapid curing. A characterization of the resulting material properties shows rather novel anisotropic properties for mortar. Finally, the potential of this approach for solid freeform fabrication of large structures is assessed.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The graphic intention is a peculiarity of the architectural drawing. It is enough to compare the ground plan of an unifamiliar housing insulated of Le Corbusier with another of Mies van der Rohe to realise the diversity of graphic styles, but is important to take conscience of the complexity that carries to interpret the symbols that appear in those documents, because as architects we either realize plans that the instructions are described or measures to be able to execute the work and in other occations representations for his edition aimed to a especialized public. For this reason, and because not always is arranged the best possible documentation, we consider that the majority of vectorisations they exist in the market don’t plenty satisfied our needs as teaching staff of graphic expression and CAD, althoug we can always be using the same systems of projection or codified representations, it is imposed a lot of times to interpret acording the context the different signs and graphic registers used. We know experimental applications that go beyond, they even arrive to generate a 3D model from a lifted hand draw that represents three orthogonal projections of it, but it isn’t less certain that its utility is restricted to fields very specialised and the option that we propose, there is not knowledge at least to us that it exist; commercially speaking. Our porpose has been to develope a symple metedology of vectorisation but adapted to the special idiosyncrasy of the needs of an architecture student that with frequency for his formation requires to generate with CAD models 2D and 3D of architectural projects from the information contented in magazines, and with them create several formas analysis. The most important difference in the matter to other systems is the interactivity of the procedure that let personify the exit file, even the wide diversity of graphic registers that it exist in the entrance, being the user only once has to identify and interpret the signs to detect, and then the process is realized automatically to any plant of the building or equivalent projection.

summary	Objectware is software supporting the object-oriented paradigm. Object orientation controls complexity through thinking in natural terms. The approach unifies all stages of complex system development: analysis, design, and programming. It applies to software design, from operating systems to CAD packages, as well as all fields of engineering design, CAD based or not. The paper discusses what next generation CAD, object-oriented CAD or CAD++ will be like by studying the philosophy behind the C++ object-oriented programming language, which most CAD++ software developers use.

title	An accelerated triangulation method for computing the skeletons of free-form solid models
source	Computer-Aided Design, Vol. 29 (1) (1997) pp. 5-19
summary	Shape skeletons are powerful geometric abstractions that provide useful intermediate representations for a number of geometric operations on solid models includingfeature recognition, shape decomposition, finite element mesh generation, and shape design. As a result there has been significant interest in the development of effectivemethods for skeleton generation of general free-form solids. In this paper we describe a method that combines Delaunay triangulation with local numerical optimizationschemes for the generation of accurate skeletons of 3D implicit solid models. The proposed method accelerates the slow convergence of Voronoi diagrams to theskeleton, which, without optimization, would require impractically large sample point sets and resulting messhes to attain acceptable accuracy. The Delaunaytriangulation forms the basis for generating the topological structure of the skeleton. The optimization step of the process generates the geometry of the skeleton patchesby moving the vertices of Delaunay tetrahedra and relocating their centres to form maximally inscribed spheres. The computational advantage of the optimization schemeis that it involves the solution of one small optimization problem per tetrahedron and its complexity is therefore only linear (O(n)) in the number of points used for theskeleton approximation. We demonstrate the effectiveness of the method on a number of representative solid models.

title	Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source	Eindhoven University of Technology
summary	The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process.Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type.A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent.If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used.By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined.The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design.Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

title	Architectural Design Based on Parametric Variation and Associative Geometry
doi	https://doi.org/10.52842/conf.ecaade.1997.x.h5q
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	This paper considers the role of the computer for detailed design within the wider architectural design process. The central proposition is that parametric modelling software is invaluable for both preliminary and developed design where there is a need for the definition, manipulation and visualisation of complex geometry. The paper begins with a definition of 'parametric design' followed by a consideration of its potential to assist or hinder the designer. A worked example will demonstrate how the elements that make up a model can be referenced to each other using a number of clearly defined constraints, the completed model being changed, modified and regenerated while conforming to pre-set conditions. This will be followed by a report on research into the implications of parametric design modelling applied retrospectively to Jørn Utzon's documented design process for the Sydney Opera House. The study analyses how conventional modelling coped with the manipulation of these forms and compares this with the potential of computer-aided iterative design refinement.

summary	This paper presents a teaching experience involving students and professors from various universities, in Italy and abroad, which began in 1996 and is still on going. The Virtual Studios on the Internet (VSI) have some features in common with the Teaching Studios planned for the new programme of the faculties of Architecture in Italian universities. These are the definition of a common design theme, and the participation of disciplinary teachers. The greatest difference is in the modes of collaboration, which is achieved through information and communication technologies. The chief result of this is that the various work groups in different places can work and collaborate at the same time: the computer networks provide the means to express, communicate and share the design project.

title	Logic based design modeling with shape algebras
source	Automation in Construction 6 (4) (1997) pp. 311-322
summary	A new method of describing designs by combining the paradigms of shape algebras and predicate logic representations is presented. Representing shapes and spatial relations in logic provides a natural, intuitive method of developing complete computer systems for reasoning about designs. The advantages of shape algebra formalisms over more traditional representations of geometric objects are discussed. The method employed involves the definition of a large set of high level design relations from a small set of simple structures and spatial relations. Examples in architecture and geographic information systems are illustrated.
