summary	Architects have a renewed interest in surface structures and the renewable resource of wood, along with advanced digital design, analysis and machining techniques, offers a way of manifesting these forms. Wood is easily machined and has bending properties that lead to the ability to form curves. This paper looks at the properties of wood, informing design through its material characteristics. The research presented here contributes to this discourse through the development of large scale timber shell structures. We propose hyper efficient structures made out of laminated wood products to provide a new solution to long span construction while satisfying the demand for agency in form generation.

summary	This paper presents a 3D Concrete Printing (3DCP) experiment at the full scale of virtualarchitectural bodies developed through a computational technique based on the use of Cellular Automata (CA). The theoretical concept behind this technique is the decoding of errors in form generation and the invention of a process that would recreate the errors as a response to optimization (Adilenidou 2015). The generative design process established a family of structural and formal elements whose proliferation is guided through sets of differential grids (multi-grids) leading to the build-up of large span structures and edifices, for example, a cathedral. This tooling system is capable of producing, with specific inputs, a large number of outcomes in different scales. However, the resulting virtual surfaces could be considered as "unprintable" either due to their need of extra support or due to the presence of many cavities in the surface topology. The above characteristics could be categorized as errors, malfunctions, or undesired details in the geometry of a form that would need to be eliminated to prepare it for printing. This research project attempts to transform these "fabrication imprecisions" through new 3DCP techniques into factors of robustness of the resulting structure. The process includes the elimination of the detail / "errors" of the surface and their later reinsertion as structural folds that would strengthen the assembly. Through this process, the tangible outputs achieved fulfill design and functional requirements without compromising their structural integrity due to the manufacturing constraints.

title	On-site Robotic Assembly of Double-curved Self-supporting Structures
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 746-753.
summary	Robotic assembly of architectural structures has been an area of research for a few decades. Yet, current methods impose a large number of constraints on the geometry of those structures. In this paper we introduce a method for robotic assembly that enables the construction of double curved self-supporting structures. Latest research challenges have focused on the assembly of sophisticated brick structures and on sensor feedback systems for handling accuracy. We propose an alternative strategy to tackle tolerance handling in complex structures that rely on geometry. The intelligence of the system lies in two main aspects: a subdivision technique that incorporates the robot’s constraints as well as the structural equilibrium of the structure during each step of assembly, in order to omit the use of scaffolding; and a match between geometric information and the robot’s movements in a robot programming environment. As a proof of concept, we fabricated a portion of a full-scale double-curved structure. The structure was assembled without scaffolding by a portable KUKA KR10 on a randomly picked site. This project aims to demonstrate an easy and simple method for robotic assembly that enables the realization of digitally generated complex geometries as concrete complex structures.

title	Design Methods for Large Scale Printing
doi	https://doi.org/10.52842/conf.ecaade.2015.2.331
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 331-339
summary	With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.

title	Cell-Based Venation Systems
doi	https://doi.org/10.52842/conf.ecaade.2015.2.573
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 573-580
summary	Venation structures in leaves fulfil both circulatory as well as structural functions within the organism they belong to. A possible digital simulation algorithm for the growth of venation patterns based on the leaf surface has been described by the Department of Computer Science at the University of Calgary.Cell-based growth algorithms to generate surface meshes have been developed by biological and medical scientists as well as artists, in order to gain an understanding of developmental biology or to generate artistic form. This paper suggests the combination of the two algorithms in order to generate the morphologies of leaves and other structures while at the same time generating the corresponding venation system.The resulting algorithm develops large non-manifold mesh structures based on local rules of division of the individual cells. The venation system develops in parallel based on the flow of the plant hormone auxin from those cells towards the start point or petiole of the leaf. Different local behaviours of the cells towards their adjacent neighbours, towards their rules of division and towards the rules of developing veins have been investigated. The eventual aim of the algorithms is their application as tools to develop architectural and structural morphologies.

title	Transient Materialization: Ephemeral, Material-Oriented Digital Fabrication
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 411-420.
summary	This paper introduces the notion of transient materialization through an exploration of the relationship between digital and material-based digital fabrication. The research was inspired by direct observations of nature’s beauty in the form of thin films. The building block of the experiment is an n-hedron structure composed mainly of soap foam, which is blown into a foam structure. The paper questions this structure’s materiality, examines its physical performance and ephemeral characteristics, and expands on its meaning through an experiment in digital fabrication. Specifically, this experiment demonstrates various configurations of dynamic and programmable foam structures on a large scale of fabrication. The fabrication interacts with the algorithm, which involves a mixture of air and helium (controlled by pneumatic valves), as well as additive chemical substances and thickening agents, all of which exist in a certain space and time.

summary	The rapid emergence of computational design tools, advanced material systems and robotic fabrication within the disciplines of architecture and construction has granted designers immense freedom in form and assembly, while retaining pronounced control over output quality throughout the entirety of the design and fabrication process. Simultaneously, the complexity inherent within these tools and processes can lead to a loss of craft though the production of methodologies, forms and artifacts left with extremely recognizable residues from tooling processes utilized during their production. This paper investigates the fecund intersection of digital technologies and handcraft through core-less carbon fiber reinforced polymer (CFRP) winding as a means of creating a new typology of digital craft blurring the line between human and machine. Through the lens of an innovative wound CFRP shelter rolyPOLY completed during the winter of 2015, this paper will show the exigencies and affordances between the realms of digital and analog methodologies of CFRP winding on large-scale structures.

title	Assisted construction of non-standard wooden walls and envelope structures by parametric modeling
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 328.
summary	We introduce a parametric modeling method in the field of computer-aided architectural conception, which aims to produce non-standard wooden walls and envelopes with CNC machinery. This method explores the application of polygonal cellular structures (as patterns) on facade and envelope interventions for new and old projects. We innovate by bringing the 3D production environment complexity into the conception model to improve the production of manifold woodworking items by CNC (Computer Numerical Control) 3D fabrication. A recent experimentation, tests the entire workflow from parametric modeling to production of two full-scale prototypes. The results prove the range of inputs offered by the method to be functional, though it needs various improvements in order to optimize parametric modeling and digital fabrication procedures. Future research will focus on treating a wider range of joints via parametric modeling and deal with joint creation regardless wall deformation to expand the morphological approach of non-standard wooden walls design.

summary	The non-standard approach, widely discussed in the past years as Architecture progressively uses alternative design methods different from the Euclidean paradigm, has allowed architects to transform the way architecture is conceived and materialized. Such evolution uses computer-aided design along with automation in production to originate the environment for the aided architectural conception field in which we present a method, in its early development stage, intended to create non-standard walls and envelopes based on cellular patterns using wood as base material. We present the results obtained from modeling and building two full-scale prototypes of non-standard wooden walls.

summary	Today, 98% of megaprojects face cost overruns or delays. The average cost increase is 80% and the average slippage is 20 months behind schedule (McKinsey 2015). It is becoming increasingly challenging to efficiently support the scale, complexity and ambition of these projects. Simultaneously, project data is being captured at growing rates. We continue to capture more data on a project than ever before. Total data captured back in 2009 in the construction industry reached over 51 petabytes, or 51 million gigabytes (Mckinsey 2016). It is becoming increasingly necessary to develop new ways to leverage our project data to better manage the complexity on our projects and allow the many stakeholders to make better more informed decisions. This paper focuses on utilizing advances in data mining, data analytics and data visualization as means to extract project information from massive datasets in a timely fashion to assist in making key informed decisions for project delivery. As part of this paper, we present an innovative new use of these technologies as applied to a large-scale infrastructural megaproject, to deliver a set of over 4,000 construction documents in a six-month period that has the potential to dramatically transform our industry and the way we deliver projects in the future. This paper describes a framework used to measure production performance as part of any project’s set of project controls for accelerated project delivery.

title	Alternative Fabrication Process for Free-Form FRP Architectural Elements Relying on Fabric Materiality Towards Freedom from Molds and Surface Articulation
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 397-410.
summary	FRP (fiber reinforced polymers) is a family of composite materials combining fibers and polymers to offer exceptional mechanical properties. Its unique material properties have led to its wide application across industries. Although we witness a growing interest in the material in the architectural field in recent years, a significant barrier to its application lies in the need for a mold. The paper describes a new alternative fabrication process for architectural FRP elements that relies on fabric materiality. It suggests a mold free process, combining form finding and garment making techniques, to allow for complex morphologies, surface articulation and variation. The paper describes both the fabrication process through physical experiments, as well as the design process through the use of two design software tools. It demonstrates the potential for sustainable variation of large component facade system.

summary	Biological life manifests in space through a large diversity of physical structures perfectly bind and identifiable in the environment. This reveals that all share a common generative design process which allows them the same physical identity in all the shapes that generates, The human ecological design process used in architecture is not able yet to reach this design identity neither the spontaneous integration associates to it. Why? Because the geometrical design process used in ecological architecture and living structures are not similar. Thus, this paper proposes, through the identification of some geometrical characteristics from the growth mechanism of living structures, a process of shape generation through shape grammar. With this generation process is possible to generate, only in geometrical terms, a large diversity of architectural models with a common identity, that reveals some geometrical characteristics of spatial integration that living structures share with the surround environment.

summary	This paper outlines a research project that explores the participation in, and perception of, advanced technologies in architectural professional practice through a sociotechnical lens and presents empirical research findings from an online survey distributed to employees in five large-scale architectural practices in Sydney, Australia. This argues that while the computational design paradigm might be well accepted, understood, and documented in academic research contexts, the extent and ways that computational design thinking and methods are put-into-practice has to date been less explored. In engineering and construction, technology adoption studies since the mid 1990s have measured information technology (IT) use (Howard et al. 1998; Samuelson and Björk 2013). In architecture, research has also focused on quantifying IT use (Cichocka 2017), as well as the examination of specific practices such as building information modelling (BIM) (Cardoso Llach 2017; Herr and Fischer 2017; Son et al. 2015). With the notable exceptions of Daniel Cardoso Llach (2015; 2017) and Yanni Loukissas (2012), few scholars have explored advanced technologies in architectural practice from a sociotechnical perspective. This paper argues that a sociotechnical lens can net valuable insights into advanced technology engagement to inform pedagogical approaches in architectural education as well as strategies for continuing professional development.

summary	Large-scale airports such as Incheon International Airport have large-scale terminals, annex buildings, and numerous open spaces. An integrated space management system is required to manage these buildings and spaces efficiently. Thus, Incheon International Airport Corporation developed a 3D computer-aided design (CAD)-based integrated space management system. The major system development goal was to provide intuitive 3D-based visual information, thereby realizing an integrated space and asset management system that does not require expert knowledge of any specific field, such as architecture. This paper discusses the construction of the system and the problems that had to be resolved to achieve this goal.

title	Form Follows Flow: A Material-Driven Computational Workflow for Digital Fabrication of Large-Scale Hierarchically Structured Objects

summary	In the natural world, biological matter is structured through growth and adaptation, resulting in hierarchically structured forms with tunable material computation. Conventional digital design tools and processes, by contrast, prioritize shape over matter, lacking integration between modeling, analysis, and fabrication. We present a novel computational environment and workflow for the design and additive manufacturing of large-scale hierarchically structured objects. The system, composed by custom multi-barrel deposition attached to robotic positioning, integrates material properties, fabrication constraints and environmental forces to design and construct full-scale architectural components. Such components are physically form-found by digitally extruding natural polymers with functionally graded mechanical and optical properties informed by desired functionality and executed through flow-based fabrication. In this approach, properties such as viscosity, velocity, and pressure embed information in two-dimensional printing patterns and induce three-dimensional shape formation of the fabricated part. As a result, the workflow associates physical material and fabrication constraints to virtual design tools for modeling and analysis, challenging traditional design workflows and prioritizing flow over form.

summary	The aim of this investigation was to evaluate the performance of three wind analysis programs used in the early design stage (EDS) of a passive windbreak shelter concept for an urban context. This study compared the different workflows of these programs and the respective visualized results, identifying the differences and limitations of these tools, for design exploration. The programs tested were Autodesk Vasari, ODS-Studio, and ANSYS CFX. The results of this investigation indicate that basic computational fluid dynamics (CFD) programs such as Vasari was found to be more suitable for the observation of large-scale wind phenomena through the whole area of the shelter. Moreover, intermediate CFD tools (functions, usability) such as ODS-Studio can be used more efficiently in detailed visualization of wind interacting with design features. Finally, a more sophisticated CFD program like ANSYS CFX can be incorporated in the early design stage workflow for final verification of results.

summary	This paper introduces a counter-mapping attempt augmented by a Geoweb 2.0 platform in the context of two Belgian inner-city neighborhoods. The two aims of this project were to build a platform for the collective construction of a better understanding this dynamic super-diverse arrival environment and bring the various qualities and aspects of these super-diverse urban neighborhoods to foreground. In this study we report on the first results of this project which took place in Ghent and Brussels in 2014. Around 300 architecture students registered, interpreted and geocoded visible signs along preconceived tracks by means of a Geoweb 2.0 platform. Through field observations and interviews, the students created dynamic and interactive maps. We found that the large-scale mapping through Geoweb 2.0 makes it possible to discern different layers of use in arrival neighborhoods. These layers referred to different population groups which continuously have to negotiate each other's presence. Furthermore, the platform created the possibility to effectively and efficiently combine student fieldwork with online and offline lectures and offered students the opportunity to comment on, peer-review and learn from each other's insights. The findings will serve as an alternative information resource in the forthcoming Master's thesis graduation design studio which will be led by the first author.

summary	This paper presents a novel web-based platform that supports the analysis, integration, and visualization of large-scale and heterogeneous urban data, with application to city planning and decision-making. Motivated by the non-scalable character of conventional urban analytics methods, as well as by the interoperability challenges present in contemporary data silos, the illustrated system – coined SocialGlass – leverages the combined potential of diverse urban data sources. These include sensor and social media streams (Twitter, Instagram, Foursquare), publicly available municipal records, and resources from knowledge repositories. Through data science, semantic integration, and crowdsourcing techniques the platform enables the mapping of demographic information, human movement patterns, place popularity, traffic conditions, as well as citizens’ and visitors’ opinions and preferences about specific venues in a city. The paper further demonstrates an implemented prototype of the platform and its deployment in real-world use cases for monitoring, analyzing, and assessing city-scale events.
