title	Material Information: Integrating Material Characteristics and Behavior in Computational Design for Performative Wood Construction
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 151-158

summary	Architecture as a material practice is still predominantly based on design approaches that are characterized by a hierarchical relationship that prioritizes the generation of geometric information for the description of architectural systems and elements over material specific information. Thus, in the early design stage, the material’s innate characteristics and inherent capacities remain largely unconsidered. This is particularly evident in the way wood constructions are designed today. In comparison to most construction materials that are industrially produced and thus relatively homogeneous and isotropic, wood is profoundly different in that it is a naturally grown biological tissue with a highly differentiated material makeup . This paper will present research investigating how the transition from currently predominant modes of representational Computer Aided Design to algorithmic Computational Design allows for a significant change in employing wood’s complex anisotropic behaviour, resulting from its differentiated anatomical structure. In computational design, the relation between procedural formation, driving information, and ensuing form, enables the systematic integration of material information. This materially informed computational design processes will be explained through two research projects and the resultant prototype structures. The first project shows how an information feedback between material properties, system behaviour, the generative computational process, and robotic manufacturing allows for unfolding material-specific gestalt and tapping into the performative potential of wood. The second project focuses on embedding the unique material information and anatomical features of individual wooden elements in a continuous scanning, computational design and digital fabrication process, and thus introduces novel ways of integrating the biological variability and natural irregularities of wood in architectural design.

title	Patterns, heuristics for architectural design support: making use of evolutionary modelling in design
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 283-292

summary	Software used by architectural and industrial designers has shifted from becoming a tool for drafting, towards use in verification, simulation, project management and remote project sharing. In more advanced models, design parameters for the designed object can be adjusted so that a family of variations can be produced rapidly. With the advances in computer aided design (CAD) technology, design options can now be generated and analyzed in real time. However the use of digital tools to support design as an activity is still at an early stage and has largely been limited in functionality with regard to the design process. To date, major CAD vendors have not developed an integrated tool that is able to leverage specialised design knowledge from various discipline domains (known as expert knowledge systems) as well as to support the creation of design alternatives that satisfy different forms of constraints. We propose that evolutionary computing and machine learning be linked with parametric design techniques in order to monitor a designer’s cognition and intent based on their design history. This will lead to results that impact future work on design support systems which are capable of supporting implicit constraint and problem definition for wicked problems that are difficult to quantify.

title	Complexity, Digital Consciousness and Open Form: A New Design Paradigm
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 81-87

summary	Complexity as a result of improved design capabilities through the use of computer tools was introduced in the architectural debate since these became irreplaceable. On the other hand, not every designer is genuinely aware of the logical implications that the use of these tools may entail. Used as a simple emulation of enhanced traditional design tools—drawings and models, they do not alter the process of design significantly. However, the potential of such tools beyond their instrumentality introduces designers into the realm of digital consciousness. This paper analyzes complexity as an inherent quality of computer aided architectural design in relation to four different digitally conscious design strategies. First, the increase of complexity involved in digital architectural designs because of their potentiality to manage enormous amounts of differentiated information. Second, the complexity inherent to an open form such as parametric or generative designs may be defined. Third, the use of the computer as a smart partner involved in the design process —i.e., form finding strategies— rather than as a simple efficient machine able to repeat our abilities faster and more effectively in certain roles of the design process. Finally, it analyzes the possibility of generating parameterized typologies as a result of the openness of form, as well as the increased complexity that randomness may introduce in algorithmic design. The paper concludes with reflections on complexity vs. simplexity considering the fact that the simplicity characteristic of Modernism aesthetics and constructive values collide with the baroque formal complexity achieved in generative design.

summary	Digital tools present the opportunity for incorporating performance analysis into the architectural design process. Acoustic performance is an important criterion for architectural design. There is much known about sound absorption but little about sound scattering, even though scattering is recognized to be one of the most important factors in predicting the acoustic performance of architectural spaces. This paper proposes a workflow for the design of complex architectural surfaces and the prediction of their sound scattering properties. This workflow includes the development of computational design tools, geometry generation, fabrication of test surfaces, measurement of acoustic performance, the incorporation of this data into the generative tool. The Hexagon Wall is included and discussed as an illustrative design study.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title	Stage-based design briefing beyond the waterfall model: tracing students’ design processes in relation to prescribed design stages throughout an architectural design studio
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 199-208
doi	https://doi.org/10.52842/conf.caadria.2010.199
summary	Based on visualisations of data obtained from field observations, this paper describes and discusses how a group of ten undergraduate students of architecture negotiated their ways through the tutorials of a design studio lasting 17 weeks. The main question guiding this empirical study is how the initially prescribed linear, stage-based framework of the design studio relates to design processes as experienced by participating students and as observed by myself as tutor and participant observer. Visualisations of tutorial observations show that instead of proceeding from one stage to the next sequentially, students tend to engage in continuous and parallel re-consideration of almost all aspects of their work. This results in a process that can be described as a cumulative and layered process, and illustrated as ‘fan’-shaped diagrams. The role of the design stages initially scheduled in the detailed studio brief seems to be to gradually introduce students to increasingly advanced and challenging project scopes rather than to enforce sequential design steps.

title	Automated Cost Analysis of Concept Design BIM Models

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.

summary	The following paper deals with a performance-driven morphogenetic design task to improve the conditions of room acoustics, using as a case study the material laboratory of the School of Architecture at Federico Santa Maria University of Technology. Combining contemporary Parametric Modeling techniques and a Performance- Based approach, an automatic generative system was produced. This system generated a modular acoustic ceiling based on Helmholtz Resonators. To satisfy sound absorption requirements, acoustic knowledge was embedded within the system. It iterates through a series of design sub-tasks from Acoustic Simulation to Digital Fabrication, searching for a suitable design solution. The internal algorithmic complexity of the design process has been explored through this case study. Although it is focused on an acoustic component, the proposed design methodology can influence other experiences in Parametric Design.

title	Quantum architecture: an indeterministic and interactive computational design system
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 619-628
doi	https://doi.org/10.52842/conf.caadria.2010.619
summary	The evolution of computational design technique from mere substitution of hand drawing to customised design algorithms exhibiting a certain degree of intelligence, naturally opens up a new research frontier that studies the relationship between designers and customized design algorithms. Most of current customised architecture design algorithm adopts a deterministic paradigm to raise their design questions, that is to say, given the explicit rules and parameters, only one solution is allowed at each discrete computation step. Due to this deterministic nature, an intuitive and efficient communication between design algorithm and designer is hard to achieve, as there is almost no space for designer to step into the running generative process. This lack of progressive communication channels and the inefficiency of translating perceptual judgment into computer language directly results in the unconscious rejection of non-parameterisable design factors like intuition, aesthetic judgment and associational reasoning that are essential to any design activity. This paper introduces the quantum design paradigm as alternative computation paradigm for constructing an interactive and intuitive design system. An algorithm prototype, probability field, will be introduced to illustrate the logic and possible application of the proposed quantum design paradigm.

summary	This proposal seeks to stimulate energy conceptualization in the early stages of architectural design through the visualization of energy conditions as a dialogue in initial design configurations that is based on the integration of two software tools to facilitate meaningful learning. Students today have analytical intelligence that they have acquired through teaching themselves, and this has developed their creativity and their experiential - contextual practice; this permits effective interpretation of symbolic cognition. Digital tools of building, information modeling, and energy analysis can be related to specific features that promote this integrated design learning.

title	Non-Linear Architectural Design Process
source	International Journal of Architectural Computing vol. 8 - no. 1, 41-54
summary	The introduction of the computer to the architectural design process have facilitated the possibility to examine a large number of design alternatives by allowing continuous variation between pre defined constraints. However, for the most part, evaluation and comparison of the alternatives is still handled manually in a linear fashion by the designer. This paper introduces a different approach to the architectural design process, which calls for a multithreaded or a non-linear design process. In a non-linear design process design directions and alternatives are generated, presented and evaluated simultaneously, and in real time. As an example for a non-linear design process the Generative Performance Oriented Design model and software tool (GenPOD) are presented and discussed. Moving towards non-linear modes of design arguably increases design creativity by allowing generating and evaluating a greater number and variation of design alternatives.

title	A framework to integrate generative design techniques for enhancing design automation
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 127-136
doi	https://doi.org/10.52842/conf.caadria.2010.127
summary	This paper presents and demonstrates a computational framework that facilitates the integration of different generative design techniques to enhance design automation. The framework is based on the evaluation and comparison of four main generative design algorithms. Effectiveness of the framework is demonstrated through an example scenario. Compared to most existing generative design systems that are based on one of the techniques, which often bias the generative design process in a certain direction, new generative design systems by applying the proposed framework will provide the trigger at each stage as demonstrated in the example scenario for the designer to perceive the emergent designs from different viewpoints. This advantage will enhance design generation and automation by assisting the designer in making more informed decisions in understanding and selecting the suitable generative techniques for different design needs.

summary	It is perhaps no longer relevant to discuss digital tools purely as means in themselves; the growth of abstract systems or computational patterns for their own sake simply strain justification in light of real-world concerns such as climate change and economic crises. While growing concerns over climate change have necessitated an increased interest in sustainable urbanism and design, sustainability has done little to yet alter the morphological and typological consequences of architectural space (Hardy, 2008). In a series of overlapping research projects and design studio briefs, students, research assistants and we worked with the iterative and variable processes of Rhinoscript, McNeel’s Grasshopper and Bentley’s Generative Components to explore the possibilities of changing environmental extremes (specifically flooding) as catalysts for providing new urban morphologies and spatial organizations. Working between the master plan and the individual housing unit, we investigated arrays of terrace homes in the London Thames Valley flood zones while simultaneously exploring the potential for computational generation and parametric optimization.

summary	Digital Heritage has gained popularity recently as means of dynamically representing and reconstructing historic buildings and cityscapes. Simultaneously this new medium of visualization affords another approach to examine human-virtual environment interaction and offers possibilities of exploiting virtual environments as educational tools. At Zayed University, a federal university primarily for women citizens of the United Arab Emirates, we have integrated student-faculty research and documented and reconstructed a number of historical buildings within the curriculum of the Department of Art and Design. We have further collaborated with the animation program at Winston Salem State University in North Carolina, utilizing the motion capture laboratory at the Center of Design Innovation to literally breathe life into these reconstructions. The primary idea is to contribute to the ongoing documentation of the country’s heritage through creating “responsive virtual heritage environments” where the spectator is actively engaged in exploring the digital space and gain certain degrees of control over the course and scheme of the dynamic experience. The process begins by introducing students to utilize the diverse capabilities of CAD and three dimensional computer applications and intertwine the technical skills they acquire to construct virtual computer models of indigenous built environments. The workflow between the different applications is crucial to stimulate students’ problem solving abilities and tame the application tools, specifically when constructing complex objects and structural details. In addition the spatial and temporal specificity different computer applications afford has proven useful in highlighting and analyzing the buildings’ function within the extreme climate of the country and their role in the political-economy, particularly in visualizing the ephemeral qualities of the architecture as they relate to passive cooling and the inter-relationships between built and natural environments. Light and time settings clarify shadow casting and explain the placement and orientation of buildings. Particle simulations demonstrate the harnessing of wind and rain both urban and rural settings. The quantitative data accumulated and charted through CAD and VR programs and geo-browsers can be integrated with qualitative data to create a more holistic analytical framework for understanding the complex nature of past settlement patterns. In addition, the dynamic nature of this integration creates a powerful educational tool. This paper reviews this ongoing research project with examples of reconstructions completed across the country, demonstrating analytical and educational possibilities through the integration of CAD programs with a range of other statistical, geographic, and visualization software.

title	Collaborative Parametric BIM

summary	The paper will be focussing on a number of digital design tools used in [our groups credentials]. A new laboratory called […] is developed with Virtual Reality for collaborative architectural design. A brief description of the systems and how they are used to support a design team is given. Synchronic and a-synchronic, local and inter-local communication is made possible. Methods for introducing sustainability in the digital design process and user participation over the Internet will be discussed. The results of the author’s PhD research “Collaborative architectural design in virtual reality” are used to develop a new approach in which team members use their own specific software. Swarm design applications developed in Virtools are used at the start of a project. The objects in the swarm can be urban and architectural functional volumes. Examples of the first are houses, offices, factories, roads and water ways. Examples of the second are working, dining, shopping and waiting spaces. Relations between the functional volumes with or without constraints make the functional volumes swarm to find equilibrium. Everything is dynamic, meaning that relations and functional volumes can change any time. Alternatives can be developed using different values for these parameters and by top-down intervention. When the final global layout has been chosen, using a criteria matrix with sustainability criteria to be judged by all participants, including the future users, a next phase is started amongst professionals using parametric design software. A study into different types of parametric design software makes clear why object parametric software can be used for IFC based BIM, while the more interesting process parametric software can not. To make this clear a pragmatic description of the IFC format is given with a simple example of such a file. Future research will be proposed in which applications of different disciplines are connected through the application programming interfaces, while integrating as much as possible the building information and knowledge in the IFC format.

title	Over Constrained

summary	Parametric software has fundamentally changed the way in which architecture is conceptualized, developed and even constructed. The ability to assign parameters or numeric variables to specific portions of a project has allowed designers the potential to test variations of their design. Small changes to a single parameter can have an exponential effect on the designed object and alter its appearance beyond original preconceptions in both positive and negative ways. Parametric software also has the ability to constrain or restrict geometry to set values, parameters or conditions. This has the benefit of allowing portions of a form to remain constant or unchanged while simultaneously allowing for a great degree of flexibility in response to a design intent. Constraining portions of a design allows architects to respond to existing or unalterable conditions by ""locking down"" information within a project and then explore those portions that can change more freely. This programmed relationship between the parameter and the form, once established, can give the illusion of minimal effort for maximum output. The ease in which geometrical form can be altered and shaped by a single variable can mislead beginning designers into thinking that the software makes these relationships for them. What is hidden, is the programming or connections needed between the parameters and the geometry in order to produce such dramatic change. Finally, thinking parametrically about design reintroduces the concept of a rigorous, intent driven, fabrication oriented practice; a practice lost in a digital era where the novelty of new tools was sufficient to produce new form. Because parametric models must have established relationships to all parts of the design, each component must have a purpose, be well thought out, and have a direct relationship to a real world object. The introduction of parametric design methodologies into an architectural pedagogy reestablishes architectural praxis in an academic setting. Students are taught to design based on creating relationships to connected components; just as they would do in a professional architectural practice. This paper outlines how Digital Project – a parametric based software – was introduced into an academic setting in an attempt reconnect the ideologies of academia with the practicalities of professional practice. In order to take full advantage of Digital Project as a parameter based software, a project that creates modular, flexible geometries was devised. Produced over one semester, the project set out to find ways of controlling designed geometry through variable parameters that allowed the initial module to be instantiated or replicated into a wall condition: maintaining a unified whole of discrete components. This paper outlines this process, the results and how the outcomes demonstrates the parametric ideologies described above.

summary	This paper describes a framework for a collaborative, dynamically modifiable product model called FREAC built for the purposes of experimental software development. When developing FREAC, we attempted to realise the following properties that are typically lacking in currently available commercial systems: first, a high degree of flexibility so that it is highly adaptable to the needs of different disciplines; second, the ability to seamlessly connect different tools; third, real-time concurrent modelling by different remote partners; fourth, the ability to save a record of the entire modelling process; fifth, dynamic extensibility both for software developers as well as for the end users of the respective tools.

summary	This paper introduces a JAVA based library for parametric modeling through programming. From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depends on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations. We introduce key concepts of the library and show a use of the library within a form finding process driven by irradiance simulation.

summary	Music and architecture share not only phenomenological similarities in relation to their characteristics - like volume, timbre, tone pitch, instrumentation vs. geometry, materiality, light ambiance or perspective - but imply as well comparability in the process of creation. The investigation of digital tools that cross borders between music and architecture was the starting point for the research project „Mixer Modeling“. Against this background the paper discusses the transformation of a musical composition controller into an intuitive design tool for the generation of architectural geometries. In the same amount that the use of a MIDI-controller increases the degrees of freedom for the simultaneous activation of various parameters the definition of geometric dependencies on the level of visual programming become more important for the resulting geometry.

summary	The study of value and its transfer during the multi-disciplinary process of design is stable fodder for research; an entire issue of Design Studies has been devoted to Values in the Design Process. By scrutinising design meetings Dantec (2009) and Ball (2009) separately examine the mechanisms of value transfer between the agents involved in design (clients, designers, engineers). Dantec suggests this is best understood in terms of requirement, values and narrative; Ball proposes it should be viewed as a combination of "analogical reasoning" and "environmental simulation". If we look at Vitruvius and his primary architectural manual (Pollio 1960) we find values‚Äîin the form of firmitas, utilitas and venustas‚Äîembedded in this early codification of architectural practice. However, as much current research is restricted to design practice what occurs when value frameworks move between domains of cultural activity (such as design to construction and vice-versa) is not privileged with a comparably sizable body of research. This paper is concerned with the ongoing usage of pervasive media and cellular phones within communications and value transfer across the disciplinary threshold of design and construction. Through participation in a building project we analyse the subtleties of interaction between analogue communication such as sketches and digitally sponsored communication such as e-mail and mobile phone usage. Analysing the communications between the designer and builder during construction suggests it is also a creative process and the distinctions between design and construction processes are complex and often blurred. This work provides an observational basis for understanding mobile computing as a dynamic ‚Äòtuning‚Äô device‚Äîas hypothesized by Richard Coyne (2010)‚Äîthat ameliorates the brittleness of communication between different disciplines. A follow up study deploys ‚Äòdigital fieldnotes‚Äô (dfn) a bespoke iPhone application designed to test further suppositions regarding the influence exerted upon group working by mobile computing. Within collaboration individual communiqu_©s have different levels of importance depending on the specific topic of discussion and the contributing participant. This project furthers the earlier study; expanding upon what mobile computing is and enabling us to infer how these emergent devices affect collaboration. Findings from these two investigations suggest that the synchronous and asynchronous clamour of analogue and digital tools that surround design and construction are not exclusively inefficiencies or disruptions to be expunged. Observational evidence suggests they may provide contingency and continue to have value attending to the relationship between static components‚Äîand the avoidance of failure‚Äîwithin a complex system such as design and construction.
