INTRODUCTION - Steve Keogh

Currently at the tail end of an undergraduate architectural degree, it is interesting to reflect upon the winding road of ambiguity that led me to this point. Overwhelmed and desperately uninspired to spring into action following a demanding VCE year, I fell into a Science/Law double degree at Monash University in Clayton. Soon enough, however, I said my goodbyes to the universty life and entered into the workforce hoping to make my way as a landscaper.

Unfortunately the depth of my knowledge regarding digital architecture is quite minimal. Encouraged by tutors to work to my strengths, I delayed the conversion of written design to computer formats longer than would be advised. Nonethless, I am now quite proficient on both AUTOCAD and SketchUp and though it appears dauting, I am looking forward to broadening my skill set through the navigation and utilisation both Rhinoceros 5.0 and Grasshopper.

In the ensuing years I developed a passion for creation out of blood, sweat and tears. There is something intrinsically rewarding about looking back over your work at the end of a hard days toil and admiring your labours. Yet, after 6 long years working on both domestic and commercial projects, I finally hearkened once more to the call of university life. Wishing to expand upon my prior knowledge and experience, the logical course for me was within the Department of Design, Building and Planning. Indeed, my path up until now has been anything but clear cut, twisted and led astray by the musings of youth.

A1. Design Futuring

BIQ House

Arup 2013 ‘It is hard to say what today’s dreams are; it seems they have been downgraded to hopes – hope that we will not allow ourselves to become extinct.’1 Evidently, a disheartened sentiment pervades the writings of Dunne and Raby, deflated by the stark reality of a world undone by the fires of industry. Nonetheless, they believe that the gateway to redemption lies with the reemergence of societal dreaming, unbound and uninhibited from the shackles of modern consumerism. The liberation of the mind will ‘provide platforms for further collaborative speculation’ and critical discourse. 2 All that is needed is a spark, and the revolutionary design and implementation of the BIQ house may provide just that. Composed of an integrated network of adjoining panels, the BIQ house is pioneering the use of biomass as an alternate energy source. Algal populations are synthesised and distributed within a closed loop façade system that captures heat as a photosynthetic byproduct when exposed to sunlight. Generated heat can be used for internal temperature regulation, stored for future consumption, or distributed to the external grid network servicing the municipality. Algal communities also contribute to reduced solar heat gain during the summer months resulting in reduced energy consumption and can be harvested to extract vital nutrients required within the pharmaceutical industry. 3 Whilst only a fledgling technology, the potential is enormous as ‘design speculations can act as a catalyst for collectively redefining our relationship to reality.’4 Visitors admire the stunning morphological union of two seemingly divergent personalities and begin to reshape their own attitudinal values towards intrinsic design initiatives across a variety of scales. In this way, design speculation serves as the medium for critical discussion and collaborative discourse. Additionally, Fry asks us to consider the notion of ‘redirection,’ as a pertinent way of shifting momentum rather than precluding it altogether. 5 The BIQ house does not attempt to condemn the use of fossil fuels nor does it address the problem of irresolute consumer patterns, but rather provides a convincing and futuristic alternative path to conventional energy derivation.6

A1. Design Futuring

Dome Over Manhattan

Richard Buckminster Fuller

1960 In his article ‘Design Futuring: Sustainability, Ethics and New Practice,’ Fry contends that anthropogenic influence, facilitated by impetuous design and conceited ego, has disfigured the global environment so profoundly that the persistence of humanity can longer be assured.7 He is vexed by the misdirection and trivialisation of contemporary design practice, and challenges the antediluvian ideology embedded within current, fashionable design conception and maturation. Unfortunately, however, the systematic regulation of today’s economy ensures that ‘whole continents of social imagination’ are ‘swallowed up’ by the ruinous arm of neoliberal capitalism. 8 As such, Fry’s thoughts are echoed in the sentiments of Dunne and Raby, whom would also seek to preclude this damning influence of capitalism through ‘speculative design,’ a notion of conceptualisation that ‘thrives on imagination.’9

Figure 1.3: The geographical distribution of the proposed dome

On face value, Fuller’s proposal of a geodesic dome over Manhattan would appear to align with the bold, whimsical teachings of Dunne and Raby, yet diverges abruptly from the urban ideology preached by Fry. Fuller believed that the integration of a self-regulated environment beneath the dome would significantly reduce energy consumption associated with seasonal temperature fluctuations within individual dwellings.10 Yet, Fry urges us to consider the concept of ‘design intelligence,’ an astute notion regarding the ‘exploration of how things come into being and act beyond their mere function as material or immaterial objects;’ a concept which appears unforgivingly absent from the crux of Fuller’s plan.11 Issues pertaining to solar reflectance and absorption, maintenance schemes, ingress and egress, societal segregation and vilification, as well as the topographical positioning are simply not revealed.12 Thus, herein lies a great paradox between the two articles; on the one hand we must entertain the notion of unbound, creative dreaming, and on the other, we must balance this creative license with scholarly collaboration, verification and judicious thought. Nonetheless, Fuller must be commended for his ability to transcend the ‘layer of designer gloss’ that often pervades and indeed corrupts an artist’s imagination, guiding it down a misguided and often linear path of flawed architectural conception.13 Whilst his idea was never realised, it did inspire meaningful contemplation, innovation and heightened environmental awareness.14

National Bank of Kuwait

Foster + Partners

2013 Parametric modelling is an innovative field of design fabrication that incorporates specific design parameters to facilitate enhanced geometric exploration. The manipulation of these variables permits the efficient generation of numerous iterations within specific, predefined boundaries.15 For example, driven by unique, locally defined climatic conditions, the National Bank of Kuwait engages parametric modelling software to derive numerous prototypical variants in response to explicit design intent. The shape, orientation and dimensions of east orientated shading fins was fast tracked through the computation of numerous archetypical derivations, not feasible with traditional software. Performative analysis of each variant determined the most appropriate compositional morphology to counteract environmental factors pertaining to solar radiation, prevailing wind conditions and acoustic performance.16

Figure 2.2: The parametrically created fins

Parametric modeling has also ‘renewed the architect’s traditional role as the master builder empowered with the understanding and ability to digitally create in the material realm.’17 Form is no longer dictated by standardised parts or manufacturer’s specifications, as the architectural conception and articulation of material geometry has permitted absolute governance over the morphological composition of a building. In the aforementioned precedent, the conceptualisation of specialised longitudinal fins ensures that authoritative jurisdiction has once again returned to Vitruvian origins. The mitigation of external influences ensures that the prerogative of design now lies with the architect alone.18 There are, however, those who question the capacity of parametric instruments to align with the ‘poetics of construction’ within a capitalist regime.19 Unchartered technology coupled with great expense usually leads to orthodox form. Indeed, ‘CAD might conspire against creative thought’ as impulse and flair are bound by the aptitude of the handler to comprehend and exploit design software, not to mention the inherent limitations of the software itself. 20 Elias also alludes to the stylistic inhibitions of the Building Code of Australia and observes the marginalisation of small scale university projects as the forerunners of this cutting edge technology. 21

Museo Soumaya

Fernando Romero and Armando Ramos

2011

Foresight is an essential component necessary to facilitating design, and without it the process of affecting change will be considered a slapdash mockery of trivial intent and flawed temporality. It is essential that design be a consideration of systematic thought based on empirical data analysis and reference to past enterprise for guidance. In this way, design teams can pursue meaningful solutions based on merit and virtue ‘rather than waste their time searching for unsuccessful ones.’22 Conversely however, a case study into the Museo Soumaya would appear to contradict this logic in its entirety. Indeed, Romero and Ramos contend that ‘one of the challenges was how to realise this ambitious project without precedent or local expertise.’23 The structural matrix separating the building’s external façade from the internal environment is composed of ‘not a single repeating strut,’ and as such, the design team could not rely upon past innovation. 24 Strangely, however, the cladding element of the building’s façade was preordained and remained an inexorable factor to be contended with through reverse engineering. The prescribed hexagonal units had to be geometrically manipulated in order to maintain harmonious spacing’s between repeating units and was only achieved through the parametric assignment of family groups. Yet the key to the future lies buried in the past and it would appear a very brash, even conceited statement to stand alone in world spiraling swiftly into the abyss. 25

Collaboration, however has been attributed to the success of the now acclaimed Museo Soumaya, which insofar, appears to be a recurring thread throughout all of the prescribed literature. The rising complexity of parametric modelling techniques compared with traditional two-dimensional software programs demands relentless communication from the outset. Indeed, collaborative discourse together with the analysis of past projects straddling similar design problems has been hailed as the future of ‘solution synthesis’ and the use of computers has fast tracked this process through quicker response times and reduced critical error. 26 As such, even though this project did not engage with historical anecdotal evidence per se, Kalay would see it prescribed as the harbinger for future parametric endeavor. 27

Peters argues that ‘computation also has the potential to provide inspiration and go beyond the intellect of the designer,’ mediated by ‘the generation of unexpected results.’28 It is within these unimagined derivations that new possibilities may be explored and utilised to promote more efficient and effective avenues of design. Indeed, the proficiency of computational software was not lost on the designers of the Spanish Pavilion in Shanghai, China. The axial division of complex geometry through Rhino simplified the process of steel fabrication; a feedback loop enabled efficient revision of geometrical properties to devise components that best ‘exploits the potential structural advantages of its form;’ and a single, dynamic geometric model enabled universal understanding of the building’s systematics for all design teams. 29 The furtherance of this last point may indeed become a moot point of future architectural design as computational models remain pertinent in the occupational phase of construction, relaying integral information that can be utilised in future modelling ventures. Computation also ‘lets architects predict, model and simulate the encounter between architecture and the public,’ the benefits of which pertain to a universally harmonious building of enhanced contextual presence within the environment. 30 More importantly, the progressive nature of the digital realm will permit the synthesis of melodious form, congruent with ‘the creation of meaning,’ a notion that frequently evades modern day architectural form. 31 In this way, a design brief demanding the seamless integration of futuristic design ideology within a culturally enlightening medium became a reality. Initially, the curvaceous form required to encapsulate the design intent proved troublesome to comprehend. Yet computational maneuvering led to the revelation that this geometry, ‘when adequately configured’ would ‘behave in an optimal, structural way.’32 In other words, the envelope would support itself, if designed correctly, thereby negating the need for incoherent and financially problematic ancillary supports. Nonetheless, Peters asserts that the current, unwavering attitude of designers predominantly adheres to the ‘lone gun mentality,’ which diverges from a computational vernacular consistent with collaboration and enhanced conceptual analysis. 33 Nonetheless, as computation is slowly integrated within the design curriculum, we will begin to reap the benefits of enhanced performative deisgn.

Schumacher, contends that computational design is often ‘misunderstood as expressions of artistic or technophilic exuberance,’ oblivious and ill-equipped to deliver real world buildings on a rapidly imploding earth. 34 Whilst not a building per se, the nonLin/Lin Pavilion, acts as ‘a way station along the route from avant-garde speculation to mainstream realisation’ and showcases computation as a very real technology capable of fusing expressive construction techniques within deliverable constraints. 35 Close inspection of Forne’s work exemplifies the capacity of computation to attain a high degree of intricacy through geometric variation whilst remaining both economical and feasible as a built structure.

The algorithmic logic behind this fluid and flowery composition also demonstrates how easy it is to conform with fabrication limitations. More to the point, Schumacher deems parametric computation as the only apparatus capable of walking stride for stride with recent developments within the engineering industry, and thus ensuring that collaborative discourse remains a mainstay in future design schematics. It is for these reasons, that the nonLin/Lin Pavilion should be used as an informative example to help wrench parametricism out from the vice like grip of marginalised design and into the forefront of contemporary building. 36

Conclusion In sum, it was found that computational modelling has become an influential tool within most contemporary design circles. Architects can now test numerous best fit scenarios through the rapid manipulation of numerous variables, which until recently, would have been considered a timeworn pipedream by most software developers. This efficient method of sifting through countless design parameters ensures that the most beneficial, and economically viable model is selected to be built, which in a time of rapid defuturing, seems a pretty pertinent and influential power to have. Nonetheless, this technology is still a marginalised frontier that has not yet gained momentum within global architectural groups and may, as Schumacher contends, benefit from an innovative marketing campaign aimed at shedding the ambiguity surrounding its contentious avante garde tag. 37 This introductory period has opened my eyes to the unworldy power that now lies at the fingertips of designers from all walks of life to affect change. Be it small, medium or large scale projects, it is now our prerogative to utilise such a gift to redirect our tumultuous conditions and stay the hand of doom knocking so eagerly at the door. Although a little apprehensive at first, I now look forward to working in unison with Grasshopper to explore the relationships between the natural and built environments regarding the Merri Creek initiative kicking off in the not too distant future.

B1. Material Performance Material performance is the analysis of both the properties and behaviour of an element in order to best articulate its optimal form and use, relative to specific design parameters within the built environment. The idiosyncratic traits affiliated with each material will inform and govern the relationships between adjoining materials and ensure the integration of discrete building components into a cohesive whole. Computation is now turning towards the astute organisational hierarchy articulated seamlessly throughout the natural world, wherein seemingly complex form is generated from the efficient and economical spatial distribution of materials. As Menges explains, the analysis of material properties at the cellular level divulges an otherwise unexplored frontier of possibility.1 Currently, the notion of materiality is perceived as an ancillary cog in the pyramid of design, typically “assigned to geometrically defined elements” as a mode of embellishment and personal preference, rather than an inherent influence of fabrication. 2 The morphological composition of materials at the cellular level is neither explored nor understood, and for this reason contemporary design teams are failing to capitalise on the virtuosic qualities specific to the materials they engage. The repercussions of which pertain to reduced performative capacity and deleterious environmental impacts. Fortunately, however, computational design utilises material performance as a very significant proponent within the design agenda, and integrates the analysis of material properties as a precursory consideration within the conceptual process. 3 The ICD/ITKE Research Pavilion of 2010 is one such project, and explores the materialistic properties specific to birch plywood. As observed in figure 4.1, the pavilion is composed almost entirely from these deformed plywood strips. Empirical data derived from deflection analysis was used to determine the optimal geometrical configuration of each successive strip relative to its neighbours, the jointing type and orientation, as well as the thickness of each structural unit. The benefits of this approach are twofold. Firstly, it is the behavioural properties of the plywood strips under tension that determines the spatial configuration of the pavilion, allowing for an innovative derision of form and occupancy of space, which would have otherwise not been explored. And secondly, structural integrity was adequately achieved using materials not exceeding 6.5mm in thickness, verifying the resourcefulness of material exploration.4

B1. Material Performance

Voussoir Cloud

Iwamotoscott 2008 The structural capacity of the Voussoir Cloud is very much based on the historical works of Frei Otto and Antoni Gaudi. Underpinning their designs was an astute knowledge of the constructional forces threatening the integrity of any structural formation. 5 As such, their form finding process was facilitated by hanging chain models that articulated geometry “in pure tension with no shear or bending forces.”6 Once inverted, the tensional forces translate to units of compression, thus delivering a structurally proficient arch. IwamotoScott Architects turned to these archetypes in their quest to resolve a wholesome structure from individual modular units. Precursory designs were forwarded to engineering firm Buro Happold, where a digital assessment of the structural feasibility was conducted by inverting the design just as Otto and Gaudi did in an earlier time. Although, randomly interspersed, the vaults remain homogenously balanced through their interaction with adjoining vaulting arrangements, and it is this reciprocal bonding that keeps the entire structure stable. The modular building blocks of the Voussoir cloud are formed from a wafer-thin, timber laminate folded at its edges to produce curved, wedge shaped units. This manipulation of the geometrical perimeter imparts strength and solidity to an otherwise unreliable and elastic material. The systematic arrangement and orientation of these units was governed by parametric modelling tools relative to the degree of compression experienced at a particular locale within each vault.7 Thus, it becomes clear that the material properties of the timber laminate assumed a generative role throughout the design process. 8 Analytical exploration enabled a shrewd comprehension of the behavioural properties of the material once folded, leading to an unorthodox but effective realisation of form. Who would have thought, that a translucent, paper-thin material could double as a structurally supportive unit within the compressive armature of an arch? Furthermore, the spatial configuration of each module relative to one another also contributes an ethereal ambience within the construct. The deflection, distortion and transmission of light about the interstitial space can be attributed to the distinct geometrical kinship between successive wedges, as determined by the live stresses in a particular region.9

Successful Iterations

2.1 Façade manipulation through attractor points

3.2 Brep vertices as anchor points

The success of this iteration stems from its ability to respond both efficiently and effectively to a host of external stimuli. The capacity to regulate the openings of the structure based on specific, prefigured and freely moveable points permits generative modifications late within the design process. Simple adjustments within the algorithm can therefore account for any unforeseen alterations that may be required to bring a project to fruition, such as a complete translocation or simple reorientation. Greater parametric control can also be afforded through the addition of more locally defined points. Elemental consideration pertaining to light, shade and wind can therefore be easily accounted for. As such, the dynamic proficiency of the algorithm behind this form makes it a very enticing iteration to pursue.

The iteration seen here was achieved by establishing several predefined vertices within the archetypical model and anchoring those points to a set of Cartesian coordinates. This allowed the Kangaroo Physics engine to alter the original form without completely deforming the outcome. In this way, a definition initially designed to explore the notion of compression can also be manipulated to explore a similar concept under tension, illuminating a host of alternative design possibilities. The capacity to explicitly define values such as this may prove quite useful in the weeks to come. My affinity for this form derives largely from the aesthetic appeal of a top heavy structure balanced precariously over needle thin legs. It appears as though the slow passage of water over time has gradually eroded the material to reveal smooth sides and a poetically curvaceous form, which seemingly threatens to sweep visitors inside. This “mutability of materials” was once considered a blight within the construction industry but is now “pursued by a number of well-known architects” for its seamless expression of the natural passage of time.12 Further investigative study would seek to determine those materials capable of producing an analogous form without themselves failing structurally.

Ideally, this structure would remain as a pavilion within the landscape. The hierarchical categorisation of apertures relative to attractor points has created a unique fabric for discovery. The experiential journey is relative to both time and space as the outcome is very much dependant on the conditions present during occupancy. The dancing of light within the interstitial space; the play of shadows upon the walls; and the transition of sound are all determined by the time of day and seasonal change. Indeed, feedback mechanisms might also be incorporated to alter these apertures relative to undesirable environmental effects such as the onset of rain, traffic or wind. Thus, as Moussavi contends, “none of these specific decisions are crucial to the operation of the building interior, but they are vital to the affects they trigger in the urban landscape.”10

CONCEPTUALISATION

This form was realised through the integration of a Voronoi 3D component followed by subjectively removing superfluous geometry from the resultant iteration. In executing this algorithm, I had hoped to convey the shape of a building as an expression of the volatile relationship between man and the environment as evidenced by the roughly hewn, monolithic fragments, segmented by random voids and deep ravines. Upon reflection however, I would prefer to see a building sprout from this precursory geometry, wherein the monolithic slabs slowly morph into refined and recognisable building components pervasive throughout the construction industry. Thus, further assessment would extrapolate on this notion of evolution through a “divide and conquer” analogy as championed by Woodbury.11 The upheaval and massing of the foundations might be conceived as a single part, whilst the building itself might be considered another. Upon completion the two can be merged and refined as needed to demonstrate the manipulation of earthen materials into familiar parts and finally an occupiable space.

4.8 Sphere Collide In a complete divergence from the original definition, I explored the uniquely experimental component of sphere collide. Circular geometry is added to the fundamental shape of the Voussoir Cloud and then dropped from a height with the addition of unary force. The spheres deflect upon impact with the ground plane to form unorthodox shapes and patterns absent in other methodology. As expected, uniquely whimsical results were obtained, deviating greatly from the shape of the original pavilion. As such, this new form would be better suited as an artistic sculpture, or perhaps as an interactive feature within a children’s playground. The scattered nature of the spheres encourages a tactile exploration, unseen throughout most of the other iterations. Visitors feel compelled to feel their way through the labyrinth of spheres to unearth the secrets that lie within.

B3. Case Study 2.0

Chinese National Stadium (Bird’s Nest)

Arup 2008

The Chinese National Stadium, colloquially referred to as the Bird’s Nest, was designed as a centrepiece for the 2008 Summer Olympic Games. Throughout this period the stadium held a capacity of 91 000 but has since been reduced to 80 000 after temporary seating was removed following their completion.13 The most striking feature of the design is a series of randomly interspersed bands that encapsulate the building’s exterior and play an integral role in binding the 24 structural columns into a cohesive whole. Sitting atop these columns is a saddle shaped roof that appears as a circle when viewed from above and remains a symbolic gesture to heaven. Holistically, however, the presence of these bands alludes to “the balance of order and disorder in Chinese culture,” a notion also reflected in the transition of spaces throughout the stadium.14 Key amongst the design considerations was the necessity to ensure unimpeded views from all angles, which required an explicit resolve and astute foresight from the outset. Subsequently, the stadium was conceived in two phases. The sporting arena and constituent seating had to be designed first to ensure an optimal spatial configuration and economical design. The exterior shell could then be moulded around the interior space.15 Figure 4.3 Chinese National Stadium, Arup, 2008 The banded external shell of the Bird’s Nest Stadium

Setbacks Whilst the shape of the dome itself progressed with relative ease, I encountered a major setback when trying to simulate the randomisation of straps comprising the external faรงade. Initially I thought that shifting the list of points attained from dividing the base curves of the stadium would prove a profitable venture. Unfortunately, however, this method expressed a systematic array of bands quite divergent to the geometry articulated in the original design. My next step involved countless hours musing over the jitter component and attempting to cull points from the specified list; both to no avail.

Successful process

The foundational curves that will define the shape of the stadium must be created in Rhino and referenced systematically into Grasshopper.

CONCEPTUALISATION

These curves must then be divided and the resultant data must be set upon a single branch for it to be used.

Arcs are then created through these points before being rebuilt and lofted.

The random generation of curves is created by articulating a sphere at the stadiums centre within a bounding box and populating. Lines connect the points and perpendicular planes ensure the correct orientation.

An intersection is then found between the lofted surface and each of the generated lines, which anchors the curves to the desired geometry. Pipes are then added to give the straps volume.

Successful Iterations 6.9 Pipes relative to single attractor point

This fibrous mesh of chains seems to propagate from the very roots of the trees themselves. Thickened and robust, they threaten to entwine the unsuspecting visitor both in thought and reality, encouraging an unplanned, yet meaningful exploration about the installation. The interwoven fabric could provide safe refuge for small insects, act as a trestle for climbing plants and provide shelter to those encumbered by inclement weather conditions. The niche environments created within the fabric also encourage exploration of the interstitial space. In this regard, the reciprocal nature of this construct would appear to respond most astutely to the brief at this point in time. The use of attractor points seems a pertinent issue given the dynamism of the Merri Creek environment. A precursory site visit revealed extensive erosion to the river bank associated with steep escarpments, areas of scattered vegetation and an accelerated flow rate following periods of high rainfall. Given this unpredictability, incorporating attractor points within the Grasshopper definition will permit considerable manipulation late within the design piece, should the existing site topography significantly transform. They may also prove useful in the navigation around profound natural features such as trees, rocky outcrops or pathways that may need to be retained during installation.

9.1 Circle tangent between two curves The geometrical constitution of this iteration makes it an appealing candidate for future development and maturation. Composed entirely of extruded circles engaged at a tangent to several predefined curves, a seemingly complex shape of poetic form and dynamic interplay was achieved. As a standalone component, circular geometry is vulnerable to compressive deformation, lateral stresses and torsion and would be overlooked as a conducive building block in most scenarios. However, the interconnectedness between modules appears to play an integral role in transforming an otherwise unsuitable form into a geometry capable of significant structural bearing. The intersection of adjoining members is marked by a reduction in the effective length about a join, as once freely moveable parts become anchored in place. Thus, future analysis might centre on the affiliation of successive components to overcome deformation as well as enhanced structural depth to minimise torsion. Furthermore, the faรงade itself reads as an audacious quarrel between perception and imperception as the closely woven fibers veil the secrets of the interior space. Inquisitive observers hearken to the flicker of the faรงade as they move through the environment and attempt to transcend this external barrier through behavioural modifications such as stopping to look or moving closer to the installation. Numerous apertures also provide for a breathable space enlightened by shadow and light as determined by the time of day and seasonal oscillations.

B5. Technique: Prototypes

The prototypes observed here explore the versatility of paper to perform structurally integral tasks when manipulated beyond its standard rectilinear form. A single, notched template forms the basis of the entire design, wherein a seemingly complex shape is wrought from a relatively fundamental concept. Although not pertinent at this scale, designing with standardised parts accelerates productivity during fabrication and alleviates the financial burden pertaining to mass customisation.

Prototype 1

Figure 4.6 Single chain deformation under tension

My interest in the geometry seen here stems from the interlaced fabric exemplified in iteration 9.1 (circle tangent between two curves). I found the aesthetic qualities of the interwoven rings to be intellectually stimulating and decided to explore the morphological composition of these shapes relative to both compressive and tensile forces. As observed in figure 4.5, a single chain of interwoven rings demonstrated little resistance to deformation when placed under compressive stress and again when placed under tensile stress as per figure 4.6.

Figure 4.9 Single Chain

In response, I decided to generate three separate chains composed entirely of abutting rings, which were then spliced together through a series of predetermined notches as illustrated in figure 4.7. Interlacing multiple rings with one another reduces the effective length of ring fragments, thereby minimising deflection when stress is applied as per figures 4.8 and 4.9. Similarly, the surface connection of adjoining rings ensures that the deformation of one ring is resisted by the outward force of its neighbours. Thus, the more connections, the greater the performative capacity of the system, which makes this prototype a suitable candidate for future development. CONCEPTUALISATION 45

Figure 5.3 Traditional escarpment stabilising mesh

Figure 5.1 Site location

Figure 5.4 Proposed mesh geometry

Preliminary research has unearthed destabilising conditions along the Merri Creek walking trail. Sheer cliff faces, fast flowing water and regions of sparsely vegetated terrain all contribute to erosion and threaten the safety of passers-by. As such, I would like to propose a cylindrical netting of interlaced rings that can be draped over desolate regions along the trail to prevent further environmental decline. As disclosed in the previous chapter, this system has undergone preliminary deformation analysis and shows considerable promise as a stabilising mesh. The netting can be sculpted to fit the undulations of steep escarpments through the use of attractor points to categorically migrate smaller links where there is an acute topographical curvature. Anchor points within the mesh vertices can help bind the system to the terrain through the insertion of piles. As disclosed in figure 5.5, the Merri Creek walking trail meanders alongside the river in very close proximity. Mitigating the fragmentation and dislodgement of rock fragments ensures that these paths of circulation do not recede over time. The interlocking nature of each link may also prevent seeds from being washed into the river which can germinate in situ and contribute to the revegetation of the riverbank. Disadvantages may include the financial burden of selecting this product over generic mesh systems, however the artistic appeal may override the expenditure.

B7. Learning Objectives and Outcomes Whilst Part A was a relatively straightforward conceptual exercise, Part B is defined by an abstract comprehension of a very unique skill set. Whilst my understanding of algorithmic thinking was adequate in theory, it was severely lacking in practice, making this assignment a formidable hurdle to overcome. In particular, the reverse engineering task was an immense challenge, dogged by dead ends and the continual rebooting of Rhino when linking incompatible components. Being thrown into the deep end, however, ensured that I learned quickly from my own mistakes and is a strategy that I would condone. Thus, I now feel quite comfortable navigating around the Grasshopper environment and whilst my knowledge is still only rudimentary, the prospect of tackling Part C with conviction is now a reality. The manipulation of a source algorithm proved a fruitful exercise of exploration and discovery. Reworking an existing definition and splicing in new ones demonstrated just how significantly an archetype can be manipulated to generate previously unthoughtof form. Kangaroo Physics was a delightful mechanism to tinker with and although not fully appreciated in this assignment, I look forward to pushing the boundaries throughout Part C. Indeed, the capacity to test my prototype relative to the effects of gravity over time will play an integral role in the acquisition of a final form.

Final Proposal Figure 6.1

Figure 6.2

C1. Interim Submission Feedback The interim presentation emphasised several conceptual errors that may critically impede the maturation of my design if not addressed immediately. My initial intent was spurred on by a desire to purify the river of pollutants through the integration and submergence of spherical conduits that would filter out contaminants in the water. However, this approach was abandoned following criticism regarding the feasibility of such an installation to affect change within any testable, real world scenario. Subsequently, a secondary proposal aimed at embellishing and stabilising deteriorating riverbanks was proposed following the interim presentation. Whilst the notion itself was agreeable, initial feedback has delineated its generic and uninspiring conception, not to mention the monetary implications of installing a customised piece over long established, economical meshing solutions. Inspiringly, however, the modular shape and linkage of my geometry was met with some admiration and the generative simplicity, contextual malleability and aesthetic allure ensure that the form can be developed if repurposed within the landscape. As such, it was suggested that revisiting the site and re-evaluating my proposal relative to detailed site characteristics may ensure an inherent environmental connection. Topological specificity may also enhance the design persona through the exploitation and integration of site data within parametric definitions, which at this stage, is very much absent from preliminary design ideology.

The Blue-banded bee and echidna are among those species currently monitored by the Merri Creek Management Committee.

As detailed by the Friends of Merri Creek community group, one of the more pertinent tasks performed by the team involves the compilation of empirical data pertaining to the behavioural interaction of animals within their environment. “Their response to habitat restoration and revegetation along the creek” must be monitored in order to accurately develop strategies for future environmental projects.1 For example, a particular species of bird may demonstrate a predilection for one type of tree over another, which is useful when determining the precise catalogue of plants required for future revegetation schemes. As such, my amended proposal will seek to facilitate the accumulation of such information through the integration of a facility whereby the behavioural affairs of indigenous animals can be monitored with only marginal interference. Apertures will need to provide unencumbered views of the surrounding canopy and understorey without fully divulging the presence of onlookers. The cylindrical polymer disclosed in Part B, will remain the foundational unit of the design for its metaphorical resonance with the cyclical nature of life, not to mention its malleability under both tension and compression when integrated with analogous chains. Ideally, the structure itself would also provide seasonal viewing opportunities through the provision of adequate shade and shelter from the elements.

Inspiration/Precedent Project

The Centre for Education and Research in Environmental Strategies (CERES), is a community based initiative concerned with fostering strong societal bonds regarding the health and vitality of the Merri Creek ecosystem. One of the more engaging features on the site, and of particular interest to me, is The Bike Shed, a geometrically unique installation composed entirely of antiquated bike tyres and rusted out rims. 2 The capacity to seamlessly encapsulate and define a space with an unorthodox shape has inspired me to investigate the malleability of the circular form in greater depth. As seen in figure 6.3, the provision of spokes within the rim provides a bicycle tyre with adequate structural support to resist compressive forces, making the incorporation of analogous rectilinear components an ideal starting point for prototypical analysis. Nonetheless, I would also like to consider alternative structural remedies such as the independent linking of parts without the need for auxiliary members such as this.

2) Arcs are transcribed between the two curves and lofted along their length. Cull pattern is then used to determine the appropriate spacing of joints relative to each cladding module. This can be utilised once the geometry of the surface has been agreed upon.

3) Isotrim is used to divide the lofted surface into equal parts which will ensure the standardisation of components for laser cutting.

4) The subsurface is then exploded into itâ&#x20AC;&#x2122;s constituent parts before creating two independant nurbs surfaces from the resulting points. Sliders were used to determine the shape of these surfaces based on what was perceived to be an ideal viewing aperture.

CONCEPTUALISATION 57

Successful Iterations The final algorithm has been configured to enable the efficient manipulation of cladding modules relative to the changing shape of the observatory. Confining the geometric properties to a specific, isoparametric subset, ensured that the resultant geometry would always be a repeating set of identical units, ideal for fabrication en masse. As such, the generative capacity of the definition enabled me to explore countless variations with little to no fuss. The main focus of each manipulation was to investigate a uniquely shaped aperture that would not only permit unimpeded views of the surrounding landscape but also attract animals such as birds and possums. Initial circular forms were deemed unsatisfactory based on their undesirable curvature for animals to grasp and walk around on, not to mention the vulnerability of insects in such an open and visible environment. For this reason, iteration 6 was deemed the most appropriate form, as the apertures were wide enough to view wildlife interactions without disturbing the natural progression of events. Acute angles and tapered geometry were also believed to provide adequate protection for insects to thrive within the interstitial space.

CONCEPTUALISATION 59

C2. Prototype 1 - Polypropylene Bands The first prototype is little more than an elongated band wrought from black polypropylene, doubly notched along its length and laser cut for precision. Initial expectations assumed that exotic configurations could be achieved through these variable lock and key insertion points together with a high degree of rotational variability about each bolted connection. Nonetheless, the Grasshopper definition stipulates the use of sharp angles throughout the majority of the design, which unfortunately could not be reciprocated in the physical realm. Where the curvature of the shape turns sharply, adjoining circles were observed to distort and pop out of the grooves which contained them. The furtherance of this prototype would therefore require an auxiliary fastening component to prevent the tectonic dislodgement of parts, or a broadening of the angles composing the structure. However, increasing the angle would mean that the proposed form would extend beyond the predefined boundary as outlined in the brief and as such, this approach had to be abandoned.

Prototype 2 - Steel Rings With Axial Connector

Prototype 3 - Steel Rod Figure 7.7

In contrast to the malleability of the material explored in prototype 1, this analysis investigated the behavioural responses of a thicker and more rigid material to bending. Steel strips were manually folded, welded and drilled to allow for the insertion of a four-pronged connector. Whilst the linking of consecutive parts proceeded efficiently, completed parts often came loose and fell away because I had not devised a locking mechanism to fix the rings in place. Furthermore, the intelligence of the connector limited the spatial exploration to a very specific domain and as such, replicating the curvature of the observatory, as defined by Grasshopper was unachievable.

The insertion of a steel rod to link successive parts was considered given the efficiency of construction and the mass standardisation of parts. Unfortunately, however, the orientation of parts was deemed to be a very one-dimensional approach to parametric modelling and was quickly discarded.

CONCEPTUALISATION 63

Prototype 4 - Hanging Chain Figure 7.8

In place of the four pronged connectors used in earlier experimentation, steel wire was cross threaded along the axial plane of each ring and fixed at specific locations prescribed by Grasshopper. This alteration now provided the capacity to explore space where its predecessor had not, which meant that the desired curvature of the design could conceivably be met. The steel rings also provided enough structural integrity to resist the compressive forces exerted by neighbouring rings, which enhanced the accuracy of the model and therefore its quality. Even a slight deformation in the size and shape of a single component would adversely affect the connection of successive parts as seen when trialling polypropylene. Nonetheless, whilst this prototype displayed the most encouraging feedback to date, the circular structure arguably did not really push the parametric capacity of Grasshopper. Despite its structural relevance, steel was also deemed an inappropriate material with no contextual relevance to the site and was jettisoned before future prototypical analysis.

Prototype 5 - Laser Cut Luan Plywood (2.7mm) Connected With Steel Wire Figure 7.9 This prototype exists as a pastiche of the aforementioned techniques and combines the flexibility of a tensile cable with the rigidity of timber in order to explore a much more intimate connection between adjoining modules. A steel wire was woven through the core of each successive unit based on the arcs created in Grasshopper, which were used to loft the algorithm. In doing so, I hoped to express the poetics of the form without cluttering the experience with superfluous geometry. However, whilst the computational model appeared as a fully functional, rhythmic distribution of units, recreating the model in the physical world proved to be a farcical escapade of impractical endeavour. Each hole for the wire to pass through had to be manually bored using a pedestal drill and clamp, which undermines the efficiency that should be attributed with parametric design. Furthermore, the timber substrate was far too thin and often split when boring the holes and the malleability of the wire meant that the precise alignment of sequential units was impossible to realise. Slight variations at the beginning of the project soon snowballed into ruinous misalignments that deviated from the form prescribed in Grasshopper. Thus, the notion of wire joiners was abandoned for its weak resolution and inability to be transcribed in the material world. In accordance with feedback from the final presentation, notched discs were explored as an alternative jointing system to wire as seen in figures 7.10 and 7.11 below. Whilst both trialled excellently, the necessity to bolt every connection after insertion proved ineffcient and the idea was discarded.

Construction Process Figure 7.12

Step 1: Prior to commencing construction, disc connectors were systematically organised according to their angle and placed in plastic bags to avoid contamination. A single unit mistakenly placed could snowball into very distinct and problametic issues.

Step 3: A template was created for each of the resultant bands and labelled with numbers that corresponded to the bags of joiners. In this way, I was able to mitigate the liklihood of error. Figure 7.13

Figure 7.14 Figure 7.16

Figure 7.17

Step 2: The pavilion was divided into distinct bands of alternating geometry and labelled from first to last as seen in figure 7.13. Each band was connected independently of one another before adjoining components were attached. In this way, a very systematic approach was taken to ensure efficient construction devoid of errors. I first started assembling the pavilion from the ground up which proceeded relatively unhindered for a time. However, whilst gravity ensured the stability whilst building skyward, that very same force impeded progression on the downward spiral as connectors began separating from adjacent modules as seen in figure 7.16. Whilst each notch is precisely cut, I forgot to allow for deviations in the thickness of each sheet. Thus, whilst some pieces were fittingly cosily into one another, others were loose and fell away. As such, each band was inverted and constructued so that each piece could be supported by the earlier addition as seen in figure 7.17. 68

Assessment of Final Model Figure 7.18

Figure 7.19

Whilst I am relatively happy with the finished product, one significant issue was present throughout the entire construction process. The circular connectors did not have any lateral stability unitl neighbouring pieces were placed. Consequently, they would often shift sideways which meant that the two pieces they were connecting would also shift, leading to significant deformation. Indeed, several times throughout the assembly process I found myself having to recalibrate the alignment of joints which led to lengthy delays.

C3. Final Detail Model

The future development and maturation of this design should explore the notion of notched cladding modules together with the notched discs used in this assignment. Embedding the core of each connector within the material substrate of each cladding unit ensures that laterial stability is provided as seen in figure.

C4. Learning Objectives and Outcomes In conclusion, Studio Air has been an extremely challenging, albeit rewarding subject to undertake. Whilst countless hours were spent trying to grasp the fundamentals of the software, I now feel quite confident with Grasshopper and look forward to progressing my skills in the future. Of particular interest to me was the Kangaroo physics engine, and whilst it was not a featured component in Part C, it definitely left a lasting impression regarding the capacity of some of the modelling tools now available to designers. Indeed, several of the iterations created in Part B were almost surreal. I could never have fathomed such whimsical organisations of shapes using any other software, or even by hand. However, the highlight of the software was not the generative capacity itself but rather the ability to modify shortcomings in a fully-fledged project. For example, my proposal needed a complete overhaul following the structural inadequacy of steel wire leading into the final presentation. However, a few minor adjustments to the definition thankfully saw me back on the front foot with only a minor delay. This semester also encouraged me to take my first visit to the FabLab which was an exciting experience. Unfolding geometry initially proved a nuisance and costly mistakes after the fact saw me venture back to the workshop twice. However, without incorporating such technology into my project it would have been impossible to realise the complex form that I had conceived with any real accuracy or satisfaction. Subsequently, I will leave this subject with an immense appreciation for parametric modelling tools regarding the generative capacity of speculative design and the efficiency and precision of digital fabrication.
