REFLECTION

Previous investigation of the discourse surrounding computation and digital fabrication techniques resulted in a few interesting conclusions. Design ability has been influenced by these new available technologies, and it is our duty to embrace these to improve future designs. In this changing atmosphere, it is vital to consider varying stakeholders, and produce environments which are relevant and active.

With the variability of CAD technologies, there is no longer a pressure to design with an intended visual outcome.

Rather there is an openness to explore visual language, materiality, and function, through rapid prototyping.

Design computation, rather than computerisation, has created an entirely new paradigm of design conception and generation.

We are now free to experiment with tangential ideas and draw disjointed and obscure connections. These iterative and generative design processes ensure a shift from design for the few, to futuring design, which values all aspects of life. There is opportunity now, like never before, to design for a global context. We have the potential to design for the better, and to prioritise habitat, not anthropomorphic desires.

No longer is the primary focus of design on the survival of humanity, but on exploring a healthy symbiosis of all natural ecosystems.

Historically, questioning established models of design has led to radical revisioning of the design process. Our current shift toward computation is absconding from traditional representational techniques, and evolving new form-finding techniques.

There is a kind of omnipresent ambition in architecture, to push visual expression and innovation. This is something that new technologies are allowing better than old, with a novel convergence of architectural performance and resource management1.

The fluidity of experimental architecture relies on the changing perceptions of the audience. Each highly individualised project aims to be innovative and investigate novel ideas pushed by CAD and material pursuits2.

However, here to guide an exploration of fabrication, it is necessary to limit the avenues pursued, in order to produce an in-depth analysis.

Geometry is core to almost all aspects of design and is a most useful tool for a designer. Geometry naturally involves a form finding nature and can work in conjunction with other aspects of design and design research. Some forms of geometry are particularly relevant to architecture, including ruled surfaces and paraboloids.

Ruled surfaces and hyperbolic paraboloids are generated by continuously moving straight lines through points giving the illusion of curves3. They have been widely used in architecture due to their structural elegance4 and ability to create complex shapes by segmenting forms into developable sections.

“ONE GEOMETRY CANNOT BE MORE TRUE THAN ANOTHER, IT CAN ONLY BE MORE CONVINIENT.” - ROBERT M PIRSIG

These geometries are easier to produce on a smaller, rather than larger, scale.

The skin has to to be segmented into its manufacturable sections, then the appropriate supporting structure put into place, while meeting all the structural constraints of the building, which, without careful consideration, can incur high costs5. With the development of parametric design tools, however, designers are now able to simplify complex forms into manufacturable geometries.

An example of an interesting ruled surface structure is Frank Gehry’s Guggenheim Museum. The building is made up of different surfaces, almost all of which are flat and singularly curved, creating irregular forms. Gehry’s technique involved digitally reconstructing physical models of free form geometry, to create more developable surfaces on a larger scale6.

The Guggenheim was an amazing engineering achievement of its time, highlighting the benefits of ruled surfaces.

When compared to doubly-curved surfaces, which are only producible at a smaller scale or at a high cost, ruled surfaces are more realistically achievable.

In the case of Gehry’s work, the surfaces were broken up into a series of planar quads, and then developed into connecting strips to create smooth faces (Fig 5). These were then pre-fabricated, allowing for a much easier construction process7.

The development process of the design is where these geometries encounter the most issues. In most cases, the flow from a design to a developable form or surface is hindered. Small redesigns are almost unavoidable to rationalise free form designs.

This is because current softwares are not sophisticated enough to maximise optimisation algorithms.

Most of the current research in architectural geometries focuses on developing these softwares and making them more user friendly, to open up pathways into novel construction-aware tools8.

Tessellation is the formation or arrangement of elements in a checkered or mosaic pattern, without any overlaps or gaps. The term comes from the Greek tesseres, meaning ‘four’, as original tessellation tiles were four sided (square). Tessellation appears often in nature, has been popular in various art forms, and is rich in mathematics9.

There are four different types of tessellation - regular, semi-regular, monohedral, and aperiodic.

Mathematically, a regular form consists of a polygon where all sides and angles are equivalent10.

A regular tessellation therefore consists of congruent regular polygons.

Semi-regular tessellations are an adaptation of regular tessellations. They are constructed from an arrangement of regular polygons around a vertex point. Sometimes these configurations are called Archimedean, in honour of the third-century BC Greek Mathematician who ‘discovered’ them11.

Monohedral tesselations are constructed using only one shape, arranged with itself. These are primarily known through the work of M.C. Escher.

Escher created mesmerising artworks using morphing monohedral designs, illustrating how something simple can become complex through subtle variation and repetition12.

Aperiodic tessellations may not even be classified as tessellations, but they are the most common in architecture.

Originally found in medieval Islamic architecture, these geometries are usually five-fold symmetrical. This allows a pattern to keep emerging and evolving13. With CAD technologies however, it is possible to generate tessellations which do not have a base symmetry, but rather ’grow’ from their neighbouring tiles.

“WE ADORE CHAOS BECAUSE WE LOVE TO PRODUCE ORDER.”

A modern exploration of aperiodic tessellation is found at MIT, in the passageway between Buildings 56 and 66, where VoltaDom stands. VoltaDom is an installation by Skylar Tibbits, mimicking traditional vaulted ceilings, but replicated in the hundreds.

This relationship to past allows the installation to become sculpture, but it is also an exploration of materiality and digital fabrication.

VoltaDom attempts to expand the notion of the architectural ‘surface panel’ by intensifying the depth of a double-curved vaulted surface14.

The assembly of this complex design remains simple by transforming the curved vaults into developable strips.

This application of geometrical theory to produce a highly intricate design takes place towards the end of the process, to translate ideation into reality.

VoltaDom uses ‘oculi’ to administer light into the walkway. This is done by controlling the depth of the domes, and allied apertures15. The relation of the elements in this aspect becomes apparent, creating the tessellation effect. Without the light penetrations, this structure would not be easily identified as a tessellated design.

Where traditional tessellation suggests movement, this structure becomes dynamic. Perhaps the shift from a 2D to a 3D arrangement of forms is responsible for this. VoltaDom is pushing the boundaries of tessellation further, manipulating older relationships into a new language.

Sectioning is a fabrication technique based on constructing developable profiles to express a non-developable surface where the outcome can be read as a unitary form16. It creates an evocative impression, lightening the form and producing something very gestural.

Systems used to express these forms include waffle grids, weaving and contouring. Aesthetic characteristics arise from the scale, density and expression of individual sections, as well as materiality. Greater spacing between sections leads to beautiful expressionistic outcomes, whereas density produces almost monolithic designs.

This technique is echoed in materials such as plywood and laminated timber products. Although here sections are combined before a surface form can be expressed, and constructed products are no longer developable surfaces. Sectioning can also be used to highlight material expression, particularly in those which have strong fibre direction.

â&#x20AC;&#x153;IT IS THROUGH ORNAMENT THAT MATERIAL EXPRESSES EFFECTS.â&#x20AC;?

- FARSHID MOUSSAVI

Controlling light infiltration is one of the most common attributes that a sectioning design will employ.

Negative space between sections creates apertures. By controlling these apertures light, ambience, and atmosphere can be skilfully regulated.

This design technique also expresses movement and dynamism far more effectively that a solid form could.

The eye is drawn to move across the sections, understanding them simultaneously as a individual elements and whole.

One Main, by dECOi Architects, is an excellent example of a parametric design that utilised a direct work flow of CAD to CAM, to construct developable sections which are the inner skin of the penthouse office17.

One Main employs both sectioned material (plywood) and the technique of sectioning (contouring) to create form. The elements were entirely prefabricated and required very minimal formal documentation, an advantage of digitally automated construction. The overall form is controlled to integrate the logistics of infrastructure, utilities, and the specific requirements of ventilation and storage. The spacing of the sections is dynamic and responsive to functions, illustrating the versatility and flexibility of the design and the finesse of the parametric control.

[12] O

While form and materiality were the central ideals for the design, functionality and program have not been compromised. The design has created a permeable skin that allows access to services yet artfully veils the mundane aspects of an office space.

The ‘organic’ aesthetic of the skin creates an interesting dichotomy with the function of the space creating an outcome that is both intriguing and stimulating.

ATH STATION BY SANTIAGO CALATRAVA

In contrast, an example of sectioning which is aesthetically driven and has less integrated functionality is the World Trade Center Transportation Hub, by Santiago Calatrava. The overall effect is arguably more mesmerising than One Main, but the use of sectioning is primarily ornamental.

The design was informed by the evocative image of a bird leaving a childâ&#x20AC;&#x2122;s hand18. The form artfully describes movement, while the sectioned apertures maximise natural light penetration.

The sections contribute to the structural stability of the building, forming a skeletal system. Sadly, the application of the sectioning sojourns there.

Human interaction and circulation are not effectively informed by the sections and the main entrances to the building are not influenced by the apertures created between sections.

Internally, the circulation - a critical aspect in a busy transport hub - is also underrepresented by the external forms. The density of the sections rarely changes to facilitate a change in space, light penetration, or function as is does in One Main.

The building is a bold sculptural gesture, yet displays a lack of parametric design finesse and overall cohesion.

SELECTION CRITERIA The brief for this project outlines that we are designing for echidnas, and that to produce these outcomes we must be using the ABB robots. The iterations on all of the previous pages were mere explorations of what is possible within Grasshopper, and various plugins. To select which of these iterations will be most useful to us in developing our design we have to establish a set of criteria. The brief already sets two criteria that can be followed: . The outcome should be developable by the ABB robots and the hot wire cutting process. . The design should be relevant and responsive to echidnas.

We did not want to be limited completely by only these criteria, so we developed another guideline to follow when selecting which designs to use to inform our design: . The aesthetic of the design must be visually interesting both to humans and echidnas.

An application of these criterion to our matrix explorations has led to the selection of the following designs.

GEOMETRY 1. This iteration focused on a straight line geometry on a single plane. It was created using the Exoskeleton plug-in, and playing around with the radii. To create the same sized end and start radius, creating a tube like form, ideal for echidnas to pass through.

2. The base geometry of this iteration moved into the 3D, by creating smaller end radii and larger start radii, the form took on a spike like structure, reminiscent of the form of echidnas.

3. The geometry for this iteration focused more on developing a system. This shape could potentially be produced by the robots, as each â&#x20AC;&#x2DC;armâ&#x20AC;&#x2122; could be separated into its own component. As each face is on its own plane it could be slowly shaped with multiple small cuts.

4. This is a further iteration of the geometry above. Interestingly this geometry was the only one that allowed the end and start radii to reach this size without causing the form to collapse on itself.

Being an almost solid form with larger faces, this iteration would be even easier to fabricate than the previous one if broken up into components.

The results generated an irregular undulating form but exploration demonstrated that image sampling any random photo would yield an irregular result with a more effective connection to echidnas would have been to sample a single aspect such as their spines.

Species C explored how a form could be generated the have the undulating sections on both sides. This addition to the grasshopper definition provided a more interesting form and insight into how these forms could react to multiple stimuli to create different surfaces.

Species D further explored a regular pattern which, with an additional grasshopper definition to transform the sections along a curve.

Since the same iteration parameters were tested across all four species, trends in how the parameters were affecting the outcomes can be observed. When selecting for aesthetics a definite â&#x20AC;&#x2DC;sweet spotâ&#x20AC;&#x2122; occurs in all species.

Species D created the most complex of forms and illustrated the advantage of further manipulating a product (reorientating them), much in the same way that post processing our foam cuts creates a more refined outcome.

THE SWEE T SPOT

Aesthetically I find these iterations most appealing. The combination of a low surface divide count and a high perpendicular frame count resulted in the smoothest forms. The high perpendicular frame count can allow for a greater number of sections with each profile being much thinner consequentially lightening the overall form.

FA B R I C AT I O N T E C H N I Q U E S For many decades, the spread of robotics through our lives has been viewed with ambivalence. Oscillating between utopian and dystopian visions, the debate of artificial intelligence forces us to confront the question of responsibility. Ambivalence will only allow us to progress so far. Still the discourse dithers from hopes for a better, technologically advanced world, to an inhibiting fear of disempowerment.

The current fourth industrial revolution has led to robotics finding its way into our mundane lives, changing our behaviours and environments in fundamental ways.

During the last decade, digitalisation had caused a radical redefinition of the field of robotics, with designers thrust to its forefront. Where once engineers and IT experts held exclusive control, now it is often designers who decide where and why we encounter robots, and how we interact with them19.

Earlier in this journal are case studies which showcase the profound impact emerging technologies have on conceptualisation. We will be using similar technologies at a smaller scale, to exploit the versatility and precision offered by these tools. In the experimental spirit of Architecture, we have wholeheartedly adopted this mode of making.

Robotics offers replicable production, allowing us to rapidly prototype designs.

The complexity available through this means of production far surpasses our own craftsmanship skills, enabling the development of high quality work.

GROUP ONE . MTG

The 6-axis rotation robots used are not restricted by their manoeuvrability, and exhibit greater precision than the human hand could accomplish. They are however somewhat restrained by their tool attachments.

The hot-wire cutting tool used for our designs operates primarily in two different modes â&#x20AC;&#x201C; straight controlled cuts, or loose semi-free cuts.

Freer cuts, produced by loosening the cutting wire, generate uneven and semi-unpredictable paths. This allows for more singularity in design, while still being repetitious. A major difficulty with loose wire cuts is the inability to accurately post-process the product, leaving underdeveloped remains with no applicable outcome. This is why we choose not to investigate them too deeply, pursuing other methods instead.

Straight cuts have empowered the creation of sharp accurate prototypes, but restricted designs to developable surfaces. This is not necessary an endall for the design though, developable surfaces can be modified in postprocessing.

The advantage of working within this restriction is that it bounds us to real things. While using digital technologies, there is no restraint, everything is possible. By applying a visceral limitation, our designs become real and plausible20.

C ASE STUDY

In 1958, Felix Candela completed Los Manantiales, a restaurant that resides along a canal in the Xochimilco region of Mexico city, and is arguably one of Candelas most significant buildings.

Candela was known for his form finding techniques in developing structures and he took a particular fascination with hyperbolic paraboloids and thinshell concrete structures21.

The overall form of the building consists of four intersecting hyperbolic paraboloid saddles, creating an eight sided groin vault. A structure that had not been attempted before on such a scale22.

One of the most striking aspects of the building was the fact that Candela had not used edge ribs on the concrete shells.

On a structure such as Los Manantiales, the dead weight of the shells themselves would cause them to bend, deform and eventually crack without an edge rib. Instead, Candela thickened the edge of each of the groins with a V-shaped beam, where the load of the building would be taken, reducing the stress on the rest of the structure.

Candela was able to express the true thinness of the building, which was a shocking 4cm, without diminishing the reliability of the structure and giving it its iconic appearance23.

Today the structure still stands, in a structurally sound condition, and maintains its majestic presence.

[16] HYPERBOLIC PARABOLAS IN LOS MANANTIALES

[17] LOS MANANTIALES . FELIX CANDELA

GROUP ONE . MTG

When challenged with reverseengineering Los Manantiales, we first took the approach of trying to understand the geometry and overall form of the building from visually observing it. Our first attempt involved lofting a curve to a single point, and then replicating that surface 8 times.

After developing the form with the hot wire cutter we soon realised this was not the shape we were after, as it did not have the saddle curve on the top.

This led to the realisation that we needed to use a hyperbolic paraboloid. The form of Los Manantiales consists of four hyperbolic paraboloids that intersect as shown in figure 16. Using the material sizes available, we attempted to model a single section of the form.

To develop the correct cut for this shape, the floor plan of Los Manantiales was referenced into Rhino, to get the right scale, and then a hyperbolic paraboloid surface was created over the top. The top points of the paraboloid were extended to create a more elongated saddle, that was closer to the form of the real building.

The shape of the section from the floor plan was then projected onto the hyperbolic paraboloid and used to split the surfaces, leaving us with the final form of a segment of the building.

Multiple cuts were developed to achieve this shape out of the foam which we could cast onto. To minimise waste we only produced the cut four times, and then each time offset the cut 5mm to produce a wafer thin replica.

The post processing of these cuts involved connecting the created segments together to create a rough mold of the form . Plaster bandages were applied over the top of the formwork, to create a thin covering replicating the thin-shelled concrete of the real design. A coat of plaster was used to smooth over the roughness and then the final cast was sanded down to the final product as shown in.

Through the completion of the reverseengineering project, we discovered several things. First, the ability to create complex forms through repetition.

Second, that ruled surfaces such as hyperbolic paraboloids can create smooth but structurally stable curve-like forms. Third, that despite the complex form produced, the cuts were relatively simple and easy to produce.

THE MERRI CREEK CONTEXT

GROUP ONE . MTG

The Merri creek is a unique corridor of native vegetation in a highly-urbanised area on Melbourne. Great efforts to restore this waterway to a thriving ecosystem have been made by the management groups in the area24.

Large tracts of the Merri system are almost completely comprised of native vegetation creating suitable habitat for many of Australia’s emblematic animals including the platypus, echidna and kingfisher.

The Merri Creek provides a space in which people can interact with Australian “bush” in a relatively unconstructed way, resulting in a more rewarding experience than that of visiting a zoo. The creek is highly accessible through bridges and paths leading to an area which is used for a diverse range of activities.

Large areas of the of native riparian systems are thriving but they are frequently dissected by human interventions. Interferences include urban encroachment and circulation routes.

Key disturbance regimes for native wildlife include noise and vibrations from the roads that cross the creek, roaming domestic animals, pollution from stormwater, flotsam rubbish, fences and retaining walls that inhibit movement of terrestrial animals, and the concrete paths with experience a high concentration of activities.

Consequently, at the scale of a native animal the Merri encapsulates many small isolated healthy systems, but there is a lack of overall connectivity.

ECHIDNAS One of Australia’s most distinct animals, the echidna is a small mammal covered in coarse hair and quilles. They are one of the only three extant species of monotremes in the world, which combine reptilian and mammalian traits, making them a unique part of Australian culture.

Echidnas have been termed ecosystem engineers25, as they play a key role in topsoil turnover when they scourge for food and dig their burrows. This creates fertile soil for other flora and fauna to thrive. On a site such as the Merri Creek, where most of the habitat has been lost, this process of soil turnover is essential in maintaining a flourishing ecosystem in the remaining patches of habitat.

When trying to design for echidnas, physical and behavioural attributes must be considered. The average size of an echidna is about 30-50cm long, and 10-20cm tall.

Because of their bone structure, which consists of a reptilian pectoral girdle at the front and a mammalian pelvic girdle at the back, echidnas have a waddle-like walk. This prevents the echidna from being very agile, with a top speed of only 2.3km/h, and an average walking speed of a more leisurely 1 km/h.

The behavioural attributes of echidnas include mostly sleeping and eating.

They have no distinct daily routine, instead reacting to the current weather conditions, resulting in a creature which is sometimes diurnal, sometimes nocturnal, sometimes torpent (a state similar to hibernation). Echidnas have no distinct home, and are capable of roaming up to 50km.

As designers we must take into consideration all these aspects of the echidna to work out the best way to facilitate the echidna and meet its needs.

DESIGN PROPOSAL CONNEC TIVIT Y

Through investigation of the echidna and Merri creek, we decided that our focus will be on connectivity. We identified this area for a variety of reasons.

The Merri creek is a dynamic waterway which forms deep fast flowing rapids in some areas and gentle shallow creeks in others.

The system is prone to flash flooding which, in conjunction with the deep areas of the rapids, poses a barrier between the two riparian ecosystems on either side. Consequently many organisms exist in two separate corridors with minimal interaction.

While echidnas can swim, long stretches of the Merri are not ideal for their passage, especially when water levels are high. In addition to this, many local residents allow their dogs to swim in the creek. This poses a great threat, as dogs are more agile than echidnas.

Even if the dogs don’t pose a direct threat, their scent will cause distress for the echidnas, as well as other native animals.

Merri Park

The area chosen for the deploy of our design encompasses the Phillips Reserve and Merri Park. This area consists of relatively intact native vegetation, with a large mass of topsoil and leaf litter, and minimal disturbances such as road crossings and urban infringement.

The creek becomes deeper in this area with a fast current making it less than ideal for an echidna to cross, yet the divided green space is perfect for echidna habitation. Implementation of a bridge in this area would effectively connect the two areas, increasing the potential foraging range for animals in the area and allowing any echidnas on either side to interact.

The footbridge in this area creates an opportunity for residents to observe and interact with the design. This could raise some awareness of the echidnas, while effectively creating a safe, nondisturbed animal crossing.

The design is informed by creating a measure of control over what can use the bridge. The entrances on either side are only just large enough to allow an echidna to enter, creating an exclusion mechanism for dogs, cats, and people.

The ‘roof’ of the design must be irregular to prevent people from attempting to walk or ride over it, and there must be sufficient space between sections to allow light penetration and air flow.

Along the banks off the river would be multiple, spread-out entry points for the echidnas, increasing the likelihood of an echidna finding and using the bridge.

This multi-entry design also means that, in the off-chance that two echidnas are using the bridge simultaneously, they would not get trapped and instead have several avenues of escape.

The path of these intersecting elements will ideally follow a natural or organic flowing form, guiding the echidnas forward.

This cut was designed to create a tubelike platform with a spiky aesthetic to reflect the echidnas. The cast of this one unfortunately broke, as the small spikes were too thin to maintain their form in the formwork removal process.

The idea was to create several of these elements, and then join the baseplates to create a cohesive whole. Unfortunately the cast broke when removing it from the mold. The baseplate was too thin, and the wings too heavy, for the connection to survive.

CASTING PROCESS

As a knee-jerk reaction to failings in the previous prototypes a extremely simple system of sectioning a form cast was devised, and tested in plaster.

The slenderness of the concept was lost in the material and the scale was ill suited to expressing the desired aesthetic.

This casting process also explored casting other objects in the plaster.

Small plastic tubes were placed in each segment, though which bamboo sticks were then fed. This could have been used as the connecting members in our design.

FINAL DESIGN GROUP ONE . MTG

In this prototype we are aiming to create a light, ephemeral gesture using developable sections, which abstractly mimic an echidna curled up.

The uneven spikes inhibit people from crossing over the top while the small entrances inhibit anything larger than an echidna from entering the bridge. The flat base plate allows for accumulation of leaf litter and dirt, eventually resulting in a natural buildup which is not-dissimilar to what is found on the banks of the Merri.

The undulating form of the bridge intrinsically mimics the undulating nature of the Merri creek.

The spaces between the sections allow filtered light penetration.

The interior environment created by this would replicate the light patterning natural to the forest floor. Ideally, this would create a more comfortable area for the echidna, evoking feelings of comfort from being underneath, catering to the echidnas aesthetics for a safe environment.

WHERE WE ARE HEADING After the feedback from our interim presentation, we want to move forward with creating the form of the bridge using a method other than casting. We will definitely continue pursuing casting for the connecting bottom-plates, however, the level of detail we want to achieve for the cover does not make casting a feasible option.

We also want to focus more on developing our form so it incorporates geometries that add to the stability of the structure itself. We will begin research for this with Los Manantiales, as the hyperbolic paraboloid is a perfect example of the type of geometry we will require. We will aim to incorporate the geometry with the visual aesthetics we desire, to find a conglomeration of practicality and beauty.

Some of the other aspects of our design that we are going to reconsider include the spacing of the entry points. Rather than having them concentrated in one area, we want to explore spreading them across the banks. This will hopefully provide better access for the echidnas and encourage them to cross the river.

We also want to explore a wider variation in the form.

Rather than having the same repeating elements, we want to experiment with creating different forms and connecting them.

Utilising CAD technologies, we will develop algorithms that can create these variations, and then we will be able to test the different aesthetics this will create. We want to move away from being inhibited by what we think is actually constructible, and the simple method of sectioning, and challenge ourselves to create a more complex design.

LEARNING OUTCOMES Through an exploration of cutting, casting, and materiality tests we were able to develop a suitable understanding of what the limitations of the design tools we had were, and how to use them to the best of our advantages. Our approach to our design process at this point was a combination of computerization and computation. We used tactile medias to test our designs, because we had trouble visualising a satisfactory outcome using CAD technologies.

When it came to developing prototypes for our design proposal, we took up some aspects of our reverseengineering project - Los Manantiales

by Felix Candela. However, we did not fully understand how the geometry of the building aided its structure, and this was something which would have helped our design development immensely.

From the production of our Los Manantiales prototype, we did however learn how to divide larger, complex geometries into smaller, developable sections.

We were limited in our designs by selfimposed restrictions. We used plaster continuously, even when we had evidence that this would not work for the type of structure we were envisioning.

We worked in sections, when instead we should have looked at geometry and the potential of self-supporting structures. Going forward these are all things which we might explore.

We did however produce interesting outcomes, and embraced new technologies and fabrication techniques in an attempt to design a non-de-futuring structure.

GROUP ONE . MTG

We considered varying stakeholders, and produced an environment which is relevant and active. Utilising the variability of CAD technologies, we designed without an intended visual outcome. The openness of our process allowed us to explore visual language, materiality, and function, through rapid prototyping.

We are designing for the echidnas, for a species where we need to prioritise habitat, not anthropomorphic desires.

We have the potential with our design, to produce something which focusses not on the survival of humanity, but on exploring a healthy symbiosis of natural and manmade ecosystems. It is our responsibility to seize this opportunity, and produce a design which betters the context, and values all aspects of life.

RESPONSE

AND REFLECTION

At the end of part B we had reached a stage in which we were trying to achieve too many things. Our final design and prototype had become weak as we attempted to address the structural components of a bridge, the experience of the echidna, the interaction of humans, the robotic fabrication and post-processing of foam.

Post processing and fabrication had become oversimplified to guarantee a result.

Continuing into final production a need of a clear direction as to what we would like to achieve must be reached.

M O V I N G F O R WA R D Upon reflection it was decided that the key aspect of our design was facilitating the crossing of an echidna.

Thus it is the echidnaâ&#x20AC;&#x2122;s aesthetic preferences that we must consider. As we wanted to design an experience.

An experience that simulated the normal environmental sensory conditions for echidnas, in the hope that the crossing of a river would be thus less daunting.

At the same time the bridge will be aesthetically pleasing to local inhabitants and thus encourage a community repose and an understanding of shared space.

The hyperbolic paraboloid was the key proponent of the Los Manantiales building.

Being a ruled surface meant that the complexity of the doubly curved form was accurately fabricated using robots.

As we explored the techtonics of our enclosure of the bridge we reinvestigated the geometry of ruled surfaces in the hope of creating a subtle sense of movement in the form as well as a structurally robust element.

Petal Evaluation The evalutaion of each shape was focused on the following four criteria: - Visual Aesthetic (V) - Structural integrity (S): Will it be subject to breaking - Aggregation ability (A): how effective is the aggregated effect in creating the dappled light affect that we are after - Tesselation ability (T): ability to fit side by side to produce more shapes in one piece of foam SHAPE 1 L V

The chosen shape ended up being a petal like one. The wider face to one side meant that it is able to express the doubly curved surface, but the shape still allows for easy control.

Curvature in petals: When testing the placement of the petal on the hyperbolic paraboloid, and altering the gradient of the hyperbolic paraboloid, we found that a wider petal and more centrally located produced the most sufficient curvature, as expressed in petal 2 and 8.

It was also noted that increasing the steepness of the hyperbolic paraboloid too much created a curvature that was too intense for the desired effect.

Aggregation and Connection

An original exploration of connections of the petals and how they could be arranged was manually done so we could gain an understanding of the physical attributes of the petals. The major concern for these arrangements was how we could best create the aggregated  effect for the dappled light.

O V E R A L L F O R M D E V E LO P M E N T The development of form was explored algorithmically in grasshopper. As we knew we wanted a wire armature system, that was used as the starting point for our form.

Creating an algorithm which placed the brep of the petal onto the wire, we started off with a fairly simple and neat form, however we wanted more variation.

To add more complexity a ‘random’ rotation of the petals and a ‘random’ scaling of the petals was also added.

This lacked the control and overall sense of flow that we wanted. It also meant that the petals were completely blocking the path of the echidnas.

GROUP ONE . MTG

Random rotation and scale created an obtrusive form

The final form resulted in both scaling and rotation within a stricter domain, and an anchor point which roughly angled all the petals the direction we were after to create a sense of flow.

While this form was not one hundred percent indicative of how and where exactly we would place the petals on the real model, it was able to give us a rough idea of how the overall form would work as a whole.

C . T WO

A R M AT U R E Early on in the design process we decided that attaching the petals to a wire frame armature system would be the most efficient way to build the structure. The first wire frame was a simple geodesic curve over a single lofted surface, connecting two points along the bridge, with the second point shifted 2 points across.

We then decided we wanted a more complex structure, so five different lofted surfaces were created for the geodesic curves, and at each point a different curve was selected, allowing for the wire to go underneath and to the side of the bridge structure.

Single lofted surface for geodesic curves.

Multiple lofted surface for geodesic curves.

CONNEC TION The next step was the consideration of how the petals would be connected to the wire. We tested just threading the petals onto the wire however this resulted in a rather messy look, and often broke the petal itself.

Gluing the petals was also considered, but while this worked on a small scale, we felt it wasnâ&#x20AC;&#x2122;t appropriate for the real thing.

Threading the foam onto the wire.

Attaching the petals using a hotglue gun.

GROUP ONE . MTG

The connection that was decided upon was attaching the petals to a smaller wire, and using them to tie them to the armature system. This resulted in a sufficient connection and a relatively easy production process.

Wires embedded blow the muslin.

This choice did, however limit us in our algorithmic control. We were not able to effectively develop an algorithm that connected the petal at 2 different points to different wires, while still maintaining the variation and control.

This is most likely due to the fact that it was outside the scope of our ability.

Each end of the wire connects to a different support wire.

The wires a twitched on securely to the armature.

STRUCTURE

As we approached construction of our final model at 1:1 scale we considered the structure of the bridge in more detail.

Though not focussing on the structure, consideration of the interaction between the enclosure, the horizontal path and the structure had to be designed.

The base plate of the bridge was to be enclosed in two beams that would form part of the primary structural system.

These two beam would act as anchor points for the wire armature and would in turn support the petaloid enclosure.

Further analysis of the proposed location announced an extended length for the bridge.

CRITICAL REFLECTION Algorithmic control was our greatest weakness. Lacking the precise control and being able to truly map the actual location of individual petals resulted in us constructing the model â&#x20AC;&#x2DC;by eyeâ&#x20AC;&#x2122;.

The multitude of rotational commands that each petal needed to undergo -relative to its unique position- was an immense task and a task we could not fathom to accurately construct a single algorithm for.

With further progression we aim to approach a representation in grasshopper more true to our conception.

Our lack of algorithmic control created vast discrepancies. Particularly our inability to model two individual connection points for each petal to intersect at appropriate point of the armature system.

While the overall â&#x20AC;&#x2DC;randomâ&#x20AC;&#x2122; effect was liked we did begin to consider more controlled patterns although were still unable to algorithmically model them.

One strategy that was considered was the model the forms along wires that did not match the armature system so as to create better connection possibilities.

LEARNING OUTCOMES After completing Part C, we have a good insight into the benefits of using parametric modelling and algorithmic design. These tools enabled us to consistently and easily alter the design as we developed the form we wanted. It aided us in creating visual representations of our explorations, and enabled us to critically assess them to select the most efficient outcome.

Through the use of the 3D modelling tools we were able to enhance our understanding of the virtual space. This was particularly helpful when using the robots, as it meant we were able to visualize the exact cuts that we were producing.

The visualisation of design elements meant that we were successfully able to express our reasoning in choosing certain aspects of our project, as we were able to place them in site, and demonstrate various lighting and visual effects.

It is evident that computational design is something that is altering the architectural world. Through our own explorations it became apparent that these new tools extensively aid designers in realising their designs, which might previously have not been imaginable. We used these tools at key points to assess our design, based on anthropocentric and biocentric criterion. The scope of our ability to use parametric tools was where we lacked in our design process. With further algorithmic exploration in form and connection we would have been able to completely digitally model our design. Another issue we faced was the processing power of our laptops. With the sheer amount of breps/meshes we had in our design, we were not able to properly create the full design, and GROUP ONE . MTG

ultimately meant we were unable to explore further options.

This being said, we did produce interesting outcomes, and embraced new technologies and fabrication techniques in an attempt to design a non-de-futuring structure. In a consideration of varying stakeholders, we were able to produce an environment which was relevant and created an active engagement with both echidnas and humans. The flexibility of our process let us explore a new visual language, materiality, and function, finally allowing us to produce a high-quality end product.

We were able to overcome a lot of our technological hangups, and moved from a very static method which we had utilised in the past, to a continuum of technological design. Through this project we were able to understand how to connect formulation and production.
