title	Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source	International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary	This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

summary	This paper discusses a collaborative project by RDAI architects, Bollinger+Grohmann and the timber construction company Holzbau Amann. The project is located in a former swimming pool in Paris and it is part of the new interior of a flagship store of the French fashion label Hermes. In late 2009, Rena Duma Architects, asked Bollinger+Grohmann to collaborate as structural engineers on a challenging design proposal within a very short timeframe. Three wooden lattice structures, the so-called “bulle” and one monumental staircase with a similar design approach characterize the interior of the new flagship store. The lattice structures are dividing the basement into different retail spaces. They vary in height (8-9 m) and diameter (8-12 m) and have a free-form shaped wicker basket appearance. Wood was the chosen material for these structures to strengthen the idea of the wickerbaskets and to create an interior space with a sustainable and innovative material.

summary	Performative Architectural Morphology is a notion derived from the term Functional Morphology in biology and describes the capacity of an architectural material system to adapt morphologically to specific internal constraints and external influences and forces. The paper presents a research project that investigates the possibilities and limitations of informing a robotically manufactured finger-joint system with principles derived from biological plate structures, such as sea urchins and sand dollars. Initially, the material system and robotic manufacturing advances are being introduced. Consequently, a performative catalogue is presented, that analyses both the biological system’s basic principles, the respective translation into a more informed manufacturing logic and the consequent architectural implications. The paper concludes to show how this biologically informed material system serves to more specifically respond to a given building environment.

title	Integrative Design Computation: Integrating material behaviour and robotic manufacturing processes in computational design for performative wood constructions
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 72-81

summary	In contrast to most other building materials, wood is a naturally grown biological tissue. Today, the organic nature of wood is recognized as a major advantage. Wood is one of the very few naturally renewable, fully recyclable, extremely energy efficient and CO2-positive construction materials. On the other hand, compared to industrially produced, isotropic materials, the inherent heterogeneity and differentiated material makeup of wood’s anatomic structure is still considered problematic by architects and engineers alike. This is due to the fact that, even today, most design tools employed in architecture are still incapable of integrating and thus instrumentalizing the material properties and related complex behavior of wood. The research presented in this paper focuses on the development of a computational design approach that is based on the integration of material properties and characteristics. Understanding wood as a natural composite system of cellulose fibers embedded in a lignin and hemicelluloses matrix characterized by relatively high strain at failure, that is high load-bearing capacity with relatively low stiffness, the particular focus of this paper is the investigation of how the bending behavior of wood can become a generative design driver in such computational processes. In combination with the additional integration of the possibilities and constraints of robotic manufacturing processes, this enables the design and production of truly material-specific and highly performative wood architecture. The paper will provide a detailed explanation of such an integrative approach to design computation and the related methods and techniques. This is complemented by the description of three specific research projects, which were conducted as part of the overall research and all resulted in full scale prototype structures. The research projects demonstrate different approaches to the computational design integration of material behavior and robotic manufacturing constraints. Based on a solution space defined by the material itself, this enables novel ways of computationally deriving both material-specific gestalt and performative capacity of one of the oldest construction materials we have.

title	Developing Concrete Polymer Building Components for 3D Printing
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 152-157

summary	The creation of building components that can be seen as sustainable, inexpensive, stronger, recyclable, customizable and perhaps even reparable to the environment is an urgent, and critical focus of architectural research. In the U.S. alone, the construction industry produced 143.5 million tons of building-related construction and demolition debris in 2008, and buildings, in their consumption of energy produce more greenhouse gasses than automobiles or industry.Because the inherent nature of 3D printing opens new possibilities for shaping materials, the process will reshape the way we think about architectural building components. Digital materiality, a term coined by Italian and Swiss architects Fabio Gramazio and Matthias Kohler, describes materiality increasingly enriched with digital characteristics where data, material, programming and construction are interwoven (Gramazio and Kohler, 2008). The research aspires towards this classification through the use of parametric modeling tools, analytic software and quantitative and qualitative analysis. Rapid prototyping, which is the automatic construction of physical objects using additive manufacturing technology, typically employs materials intended for the immediate analysis of form, scale, and tactility. Rarely do the materials used in this process have any long-term value, nor does the process - except in rare cases with expensive metal prototyping - have the ability to create actual and sustainable working products. This research intends to alter this state of affairs by developing methods for 3D printing using concrete for the production of long-lasting performance-based components.

summary	Current developments in design-to-production workflows aim to allow architects to quickly prototype designs that result from advanced design processes while also embedding the constraints imposed by selected fabrication equipment. However, the enduring physical separation between design space and fabrication space, together with a continuous approach to both design, via NURBs modeling software, and fabrication, through irreversible material processing methods, limit the possibilities to extend the advantages of a “digital” approach (Ward 2010), such as full editability and reversibility, to physical realizations. In response to such issues, this paper proposes a processto allow the concurrent design and fabrication of discrete structures in a collaborative process between human designer and a 6-axis robotic arm. This requires the development of design and materialization procedures for discrete aggregations, including the modeling of assembly constraints, as well as the establishment of a communication platform between human and machine actors. This intends to offer methods to increase the accessibility of discrete design methodologies, as well as to hint at possibilities for overcoming the division between design and manufacturing (Carpo 2011; Bard et al. 2014), thus allowing intuitive design decisions to be integrated directly within assembly processes (Johns 2014).

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 82-89
doi	https://doi.org/10.52842/conf.acadia.2011.082
summary	With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

summary	As the architectural field continues to explore the possibilities of parametric design it is important to understand that architectural computation has evolved from representations to simulation and evaluation. This paper explores the digital processes of parametric scripting as a way to generate architectural artefacts that can be realized in the physical landscape through various digital fabrication and industrial manufacturing techniques. This paper will highlight the important discoveries of the geometries and the implications the script has on the construction processes. One benefit of using parametric modelling as a component to the manufacturing pipeline is being able to explore several design iterations in the digital realm before ever realizing them in the physical landscape. Furthermore, parametric modelling allows users to control the production documentation and precision needed to manufacture. As a result, the design pipeline presented in this paper seeks to eliminate the construction processes that hinder the physical act of making architecture.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title	InfoMatters, a multi-agent systems approach for generating performative architectural formations
source	International Journal of Architectural Computing vol. 9 - no. 3, 205-222
summary	The research paper exemplifies upon a computationally intensive inter-disciplinary research driven design investigation into spatializing the relationship between digital information and physical matter. Focusing on the development of architectural scale urban inserts, the design-research work operates on the intersection of information technology, environmental design, architecture, and computer aided manufacturing domains.The research framework revolves around developing a seamless integration of the aforementioned disciplines in order to establish iterative simulation driven methodologies for generating bottom-up sustainable architectural formations. This is achieved by establishing parametrically driven relational linkages between differential data sets (environmental, social, topological, material etc), which formulate the context (both global and local) within which the proposed project has to be designed. A selforganizing multi-agent system based simulation methodology for generating resultant spatial formations, in time, based on the impacts of the parametric relationships between the aforementioned data sets is eventually embarked upon. This implies, understanding the site as a dynamic information field within which interdependent ecology of agents (representing typology of people, program, structure, speed, desired social interaction etc) with multi-level relational affinities amongst each other as well as the dynamic urban information field. The resultant self-organized multi-agent formations are iteratively mined for identifying logical three-dimensional structural patterns or subjected to programmatic and environmental need driven additional layer of structural simulation with pre-embedded material restraints. An optimized system of multi-performative components that not only populates but also serves as an integrated structural + skin system of the results obtained from the agent based simulations (based upon the degree of inclusion/exclusion of parameters such as the amount of light, sound, wind etc) is subsequently generated. These experimental projects attained the status of self-evolving ecologies of multi-dimensional agents with embodied behavioural profiles, thus providing engaged, highly interdependent design by simulation outputs. The outputs showcase a dynamic system's driven approach towards sustainable design by stressing upon the idea of cohesively binding information and material systems from the very beginning of the design process. Such approaches help in reducing post-optimization of built form and consequently allow for rational understanding of performance criteria and its impact on formal articulations throughout the design process.

summary	Robots are gaining popularity in architecture. Snøhetta has recently purchased their own industrial robot, becoming one of the first architectural offices to adopt robot technology. As more and more architects are exposed to robotic fabrication, the need for easy interoperability, integration into architectural design tools and general accessibility will increase. Architects are discovering that industrial robots are much more than kinematic machines for stacking bricks, welding or milling - they are highly multifunctional and can be used for a huge variety of tasks. However, industry standard software does not provide easy solutions for allowing direct robot control right from CAAD (Computer Aided Architectural Design) systems. In this paper we will discuss existing methods of programming industrial robots, published architectural results (Gramazio and Kohler 2008) and the design of a new user interface that allows intuitive control of parametric designs and customized robotic mass production, by integrating CAM (Computer Aided Manufacturing) functions into CAAD.

summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.

summary	The present paper discusses a novel computational design strategy for approximating architectural free form geometry with discrete planar elements by using morphogenetic patterns. We report on an ongoing research project [1], which is focused on the design of flat ornamental tessellations by using computational geometry for the discretization of curved forms rather than manufacturing curvy elements, which typically increase cost. The significance of our approach lies in the fact that it allows the designer to progressively embrace the constructive constraints and their esthetic potential already in the design stage and to follow them through to actual fabrication.
keywords	morphogenetic geometry, design strategies, user-interactiveness, design control, flat tessellations, ornamental structure.

summary	The project Knitectonics aims at exploring digital fabrication systems that facilitate optimized, adaptive and specific integrated architectural solutions (Male-Alemany 2010). It is inspired by the beauty of nature systems with their inherent efficiency and performance. The research explored on-site fabrication of monocoques shells, integrating skin and structure along with services and infrastructure, using a simple household technique. It thus embodies a self organized micro system of textures and a macro system of structures. This paper elaborates how the numeric aspects of a textile technique were used, first to digitally imitate the process of assembly and further exploited to develop and visualize a novel fabrication system, based on material research and technical experimentation.

source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 27-30
summary	The international architecture of the last decades has examples of works and architectural projects presented graphic from the two-dimensional unfolding of three-dimensional folded surfaces. These valuable individual experiences have not represented generalized strategies that can be transferred to the professional practice and to architectural education. This article uses results of more than 10 workshops (with Unfolding and Folding methodologies) developed in Chile, Argentina and Brazil to build up a pedagogy for the project that makes it possible to investigate the spatial and material properties of folded compositions in Architecture. It proposes to review and update project instruments through the incorporation of Parametric Design; 3D origami software and Digital Manufacturing.

title	Free-form Grid Shell Design Based on Genetic Algorithms

doi	https://doi.org/10.52842/conf.acadia.2011.272
summary	In the 21st century, as free-form design grows in popularity, grid shells are becoming a universal structural solution, enabling the conflation of structure and skin (façade) into one single element (Kolarevic 2003). This paper presents some of the results of a comprehensive research project focused on the automated design and optimization of grid structures over some predefined free form shape, with the goal of generating a stable and statically efficient structure. It shows that by combining design and FEM software in an iterative, Genetic Algorithms-based optimization process, stress and deformation in grid shell structures can be significantly reduced, material can be saved and stability enhanced.
