SITE ANALYSIS

TREE DENSITY

10 POTENIAL LOCATIONS ON SITE

The site analysis was divided into two primary criterias which deter-mined ten potential zones on site:

1. Human activity in relation to the bicycle path 2. Tree and vegetation density

The concentration of activity on site determined where we proposed to place the observatory installations on site, primarily the installations require a moderate to high amount of activi-ty to achieve a successful rate of in-teraction with pedestrians, however the installations are also designed to create connectivity between ac-tive and inactive zones on site, thus supporting the design in responding to issues such as fragmentation in relation to human activity on site. In order to satisfy both aspects of -hu-man activity and interaction, a mod-erate tree density bracket was select-ed. By placing the installations in moderate tree density zone, a fusion of both objectives can be achieved: the re-connection of inactive zones without discouragement caused by dense vegetation and tree lines.

Tree and vegetation density further-more influences how the installations can be placed on site as the design shall be hung or attached to/or from an object such as trees or existing struc-tures (walls). Tree density affects where we could place our location zones as the density cannot discour-age the approach to the installations as this shall compromise the success of interaction between users and site.

ANNA

Anna's project feedback primarily supported her response to on site issues such as litter pollution - By taking this example we have researched into social onsite issues: Connectivity, fragmenta-tion and human interaction on site appears only within certain spots along Merri Creek, moreo-ver transitional activities such as running and cycling are the most common actions on site.

FABPOD From Ingrid's precedent project, the Fabpod al-gorithm was adaopted to drive Part C. This was the most developed grasshopper script. We shall continue this throughout our new design pro-posal as this also best represented the aesthetic and structural qualities of the Fabpod algorithm.

Context sensitivity, green surfaces (incorpo-rating vegetation) and creating a relationship based on the significance of site and user was positively pointed out from Olivia's prece-dent project, which we shall continue through-out the new design development for part C.

C.1 DESIGN CONCEPT

The initial design start of Part C began from reflecting upon the key feedback points from the Part B interim presentation:

The new project focuses upon context sensitivity in regards to making users aware about the existence and significance of the ecological components that essentially create Merri Creek. By capturing a selection of ecological elements that users can physically observe up close, an interactive relationship between site and user is formed and the ecological system of Merri Creek can be publically valued and appreciated. Currently on site there appears to be a lack of interaction with the natural

system of Merri Creek, and we feel that this social issue shall be addressed with the new observatory design installation. The design installation is designed to encourage engaging interaction as opposed to others observed such as transitional interaction: cycling or running. Recycled plastic bottles shall be used to facilitate how ecological elements shall be placed within the design and furthermore adopting a material re-using system, supporting sustainability in regards to material life. The project shall be proposed as a head-height installation, which allows users to enter the enclosed space and observe contents within the head space.

from the external side each bottle shall feature a bio-focal lens within the neck of each bottle, allowing users to observe the ecological elements at a macro scale. However from the internal side, the base of each bottle shall feature as a coffered like ceiling feature show casing each element from the eye. The observatory targets any user on site, without limitation to language, gender or age. As a spot for observation, each ecological bottle can provide a form of engagement between children, teenagers, adults and the elderly which fundamentally provides a wide audience and likewise suggests how important the installations can be on site.

The project shall be designed so that plastic bottles will sit within each panel. Nine panels shall create the complete model. Within our design the largest panel contains thirteen openings, created to hold thirteen recycled bottles and therefore, hosting thirteen different varieties of Merri Creek s ecological system. The project overall shall feature bottles and natural elements. The value of the project shall be that the installation can exist independently or with a collection of other installations. The purpose for this is so that the model can customize its quantity according to a space. The installation can be observed from the external and internal side,

As we wanted the design to be a mini museum that could hang from the trees we ex-plored three different ways it could be used related to the overall shape.

1. A design that for multiple people used as a hanging tent.

2. As a second skin that cov-ers the whole body.

3. As a headpiece. A mini-mu-seum for one person.

Best related to our design was the headpiece for one person. As we wanted our design to be ap-proaching and self-explanatory number two would be difficult to get into and with number one people not want to get into the design if a stranger is already there. The third is easy to get into something that makes it ap-proaching.

OVERALL SHAPE:SELECTION

PROCESS:GRASSHOPPER

The geometric rules used in the FabPod project, estab-lished by Daniel Davis, guar-antees planar intersections between the hyperboloids(1). All the hyperboloids are then distributed on a sphere point-ing towards the spheres center. Several spheres that are intersected is the founda-tion for the final form of the project. Where the mid sphere is left and the others trimmed away. The shape is panelized using a spherical algorithm(1).

The middle sphere worked as a cutting object leaving all the surfaces of the other spheres.

The bottom part of the geometry left is then timed away by a bound-ing box, leaving the geometry with the right size. As the design is a headpiece the height we set for the geometry was just under a meter.

Each of the nine surfaces have to be dealt with separately. To be able to cre-ate a vornoi pattern we referred back to the sphere center. Drawing lines on to the surface from the center point.

By using the same trimming method as the FabPod when creating the overall shape it ensured us planar surfaces. To start off with, we created 9 points to be the center of 9 intersecting spheres.

A vornoi pattern is created us-ing the lines as a guide . This pattern is determining the cone location and density.

Two Layers of cones is creat-ed. First from the vornoi pattern and then offset to another layer.

In order to create opening in the cones, cylinders are created with chosen di-ameter to use as a trimming object.

The finalized surface: two set of cones with different size open-ings responding to a bottle.

All nine surfaces put to-gether to the final design.

Three elements of the model con-sist of MDF, Polypropelene and recycled plastic.

The MDF framework and disk con-nections create the structural shell of the model - A sturdy, non-brittle material that successfully works in compressive and tensile forced was required to hold the structure and cone system in place.

Polypropelene was required due to its flexible nature and light weight - Two material characteristics are required to successfully hold the concave and convex shape of each cone system without failure from material characteristics such as brit-tleness or elasticity. Polypropelene in this case is the most appropriate material choice for the model after prototype experimentation.

Recycled plastic make up the bottle system in which facilitates the concept of material recycling and furthermore holding fragments of the local ecological system at Merri Creek.

C.4 RESPONSE: FINAL CRIT PANEL

After reflecting on the fi-nal presentaton two main forms of criticism to the pro-ject were appointed: the vulnarability of the instal-lation to public vandalism and long term materiality.

In response to this, the fu-ture development of the project would focus upon solutions to these concerns. Firstly, negative social be-haviours such as grafiti can be resolved with the addition of a transparent graffiti proof vinyl or lacre (1) to the external and in-ternal skins of the instal-lations. By doing so this shall entirely eliminate the problem without compro-mising the clean, minimal-istic nature of the design. Furthermore additional in-frastructure such as locka-ble fencing could be placed around the installations to discourage acitivity during

night hours for example. Long term materiality of the design required deeper thought as this shall essen-tially influence the aesthetic impression to the public.

Two materials were chosen to repond to this issue: lam-inated wood and opaque fi-breglass. The two materials provide better performance against long term prob-lems such as weathering and furthermore can easily adapt to the geometrical nature of the observatory.

LEARNING OBJECTIVES & OUTCOMES

In conclusion to Part C, I have developed my skills in terms of applying my own knowledge to self-guided algorithmic des-inging, fabrication processing and create-ing aesthetic layouts/themes.

My algorithmic designing may be related to Grasshopper which drove the basis of the Observatory. As apart of a group I worked on the program to create the detailing of the model, particuarly the connection points. In this sense I have been able to create realistic based design requirements that have a physical,structural function, compared to part A where virtual based de-signs were created during my exploration of Grasshopper.

Furthermore the design process as a result of algorithmic designing developed very differently, Part C especially changed ac-cording to our restrictions: bottle diameters, types, material choices and connection types - This typology of problem based designing within such a short time bracket proved challenging yet rewarding.

The fabrication process of the final model relied upon laser cutting and 3D printing, however the true test of the model layed within the actual assembly stage - as fabri-cation had to be incredibly accurate (Down the to millimetre) in order for the skeletal system of the model to fit together.

This aspect proved successful due to our grasshopper script, which parametered the dimensions of each element precise-ly, for example the simple tab system was designed so that every edge had three tabs, meaning that each tab along each edge of a cone matched up with other cones in order to make the as-semblly of the model simpler.. Had this of not working the cone systems would have not connected together.

In sumary to this, I can relate my Part C progress to learning objectives 1,3,4, 6 and 7.

I can relate the Observatory project progress to how architecture and air relate to eachother in terms of paramet-ric design. Tools such as Grasshopper provide a mathematical realm in which parameters are created and used to manipulate and create bespoke qualities about a design proposal. Part C in particular can relate this to the cone system of the model - The con-cave/convex cone system was created in order to hold the plastic bottles within the structure of the model - without this system the model would not project the same impression or constructional sense.
