March 11, 1994 Jakarta, Indonesia Undergraduate Bachelor of Environments (3rd Year) Architecture Ever since I was little, I was obsessed with art, particularly drawings with curvy lines and vibrant colors, and my parents were very supportive of my interest. By the time I was in elementary, I grew an interest in science subjects and I asked my teacher what job can combine the best of both worlds: art and science? She answered an architect.

That was probably the start of my determination to become an architect. Being educated in an Asian country, I was excited to begin my next journey in a Western culture, because everything was new to me. Unfortunately (or fortunately, it can go both ways), my first semester in University of Melbourne was experiencing Virtual Environments subject under the teachings of Samson Tiew (my tutor) and Paul Loh (subject coordinator). It was my first exposure of parametric design and software engineered rendering tool. I had only mastered Adobe Creative Suite as my tools of trade, and learning Rhino from practically zero to building something such in the left image in just 12 weeks was to me, one of the most amazing thing I never thought I could achieve.

At the end of my Virtual semester, I was honored to have my project exhibited along with 6 other amazing projects at the Wanderlich Gallery on the previous Architecture Building.

At the beginning of my summer 2014, I began my internship at a residential developer team in Tangerang, Indonesia.

My role was to draft plans and contributed in designing concepts for their commercial projects, including arranging spatial elements and proposed branding concepts.

FIG 1.3: GREEN VOID BY LAVA

The geometry research field focuses on exploring minimal and relaxed surface, thus enables the geometry to achieve high efficiency of material usage. Several design approaches are going to be explored such as paraboloids, minimal surfaces, geodesic, and tensility.

One of the precedents for relaxed surface is the Green Void by LAVA. Parametrically speaking, the Green Void used mathematical algorithmic spring forces to achieve minimal surface from its prescribed anchor points. It was achievable through flexible material that resembled those of spider webs and coral reefs (LAVA, 2008).

This particular research field is really insightful for my design brief, which is creating a “hammock� or a relaxed surface through experimented geometries.

B.2. ____Case Study 1.0

LAVA Green Void

01

As mentioned previously, an interesting element of Green Void is the usage of plugged anchor points to different sides, thus allowing the surface membrane to relax and creating minimal surface. In this exercise, the initial form of Green Lava allows various iterations largely resolve around playing with the spring kangaroo definition, and the base curve of the form.

I found iteration A05 and B04 the most interesting out of all due to its nature of combining different techniques in one place.

A05 gives a fresh outlook on how the base curves on Green Lava can become apart from the similar geometry. For the time being, kangaroo forces does not seem to work well with this geometry because it is a series of curves instead of surface.

B04 gives me a glimpse of the idea for geometry: to relax a series of web surface. Therefore, I intend to explore this particular technique more with the second case study.

B.3. ____Case Study 2.0

Munich Olympic Stadium

BY FREI OTTO & GUNTHER BEHNISCH 1968-1972

In this large-scaled project, Frei Otto managed to transform a stiff simple tent into a lightweight, tensile membrane. He derived the form by experimenting with the geometry of soap bubbles (figure 5), to achieve the shape of the membranes. This project is worth noted because it was built when there were not any digital tools assistance available at that time (Kroll, 2011).

What is interesting in this building is the fact that the canopy membrane are entirely suspended by the vertical structures, and how the design allows for simple construction yet sophisticated outcome. Thinking about my own design, the vertical membranes definitely serves as anchor points that allows the form to float in the air.

Moreover, the tensile membrane allows for dramatic curves to occur across the site and building heights, giving dynamic contours sectionally as seen in figure 7 (Garcia, 1968),

B.3. ____Case Study 2.0

Reverse Engineering of Munich Olympic Stadium 01

01 Basic geometry is rectangle; with its width shorter than length as referenced to provide for wide tensile surface.

02 Transform the surface into a mesh and laying out its vertices and grid to provide connection lines for spring by deconstructing the mesh.

04

03 Bake the points in each intersection of vertices from Grasshopper.

04 The red points are picked as anchor points to provide stress to the surface. To pick the points, apply cull pattern to selectively select those points.

05 What Kangaroo definition does here is that it converts the vertices of the mesh into spring forces while being stretch by the selected anchor points. This surface will provide for the base.

07

06 Returning to the previous grid of points, pick the points at the center of the grid as tips for the vertical member to sit on the membrane. Referenced the points to Grasshopper and add it to the definition with the previous selected anchor points.

07 Apply the Kangaroo forces again and drag the new anchor points at the center to the z axis as seen in sectional view to achieve the tent-like structure.

08 Perspective view of the tensile rectangular grid. This gives us a base to achieve the semicircle form of the stadium.

Adjust anchor points while running the Kangaroo definition to achieve form 09a (perspective view) and 09b (top view).

SERIES I Panelling exploration & Developing a network of spring connection

With experimenting there are trials and errors. Initially I was reconstructing San Gennero South Gate by SOFTlab as my second case study. However, due to geometry limitation, I decided to change it to Munich Olympic Stadium by Frei Otto. Therefore, this first series of iteration took the initial form of San Gennero South Gate and explore panelling surface to develop a web of connection.

The first four of this row are mainly playing with the unary force Kangaroo definition (to z axis); I intend to experiment with the value of negative gravity in contrast to shrink the surface. This was done to achieve the base geometry for further development.

The first two of this row are made by accident; C2 was supposed to be a voronoi-panelled geometry with spring forces applied to each of the vertices. However, the anchor points were not set on the surface, resulting in infinity force applied at the end of the tube and twisting the form.

In this series, I intend to explore the tensile capacity of a surface to various anchor points. Moreover, I think it is interesting that in the reverse engineering process, the Stadium form was derived just from a single surface; which was how it was actually built. Therefore, in this process, my exploration was largely around iterating various forms from a single surface.

I found D4 interesting because it is derived from the same surface as others, however due to its twisted anchor points, it creates this valley-looking form.

This second row explores a surface I made referenced with the site condition (see B.6 for site analysis). Personally I found E2 interesting due to its maximal tensility surface; which is why I chose that form to be a testing ground for my prototype.

B.4. ____Technique: Prototypes

Early Prototypes

My first attempt in prototyping is based on previous tensile surface iterations. Using my site context as a reference, the sticks functions as trees that will be the anchor points of the surface. The net serves as the tensile surface. In this brief trial I intend to experiment about how far the surface can be manipulate until the sticks cannot support it anymore.

At this point, I still want to attempt to do more iterations because currently I do not see any of my iterations fit in the context. This is still an ongoing experiment.

B.6. ____Technique: Proposal

Site Analysis The site for my proposed design is at East Brunswick, right at the perimeter of CERES Community Environment Park.

The main reasons for my choosing are:

01 Framing the view Near my proposed spot is a large preserved gully tree with short stream of river beneath it (as seen on photo 2). The sense of tranquility is unmistakeable compared to other spots of the river; the continous rushing sound of the water streaming through the rocks attract even passerby to stop and taking in the sound of nature.

The spot that I plan to install my project provides adequate trees for structural installation.

02 High traffic with a range of users Overall CERES is a frequent elementary school children site visit target, annually held festivals and daily events which attract families and young adults, and Merri Creek track that attracts daily users.

03 Isolated Even though it is surrounded by active community space, this spot offers solitude and tranquility in the midst of it all. It does not have to be enjoyed only by one person, solitude can also be felt within close knit of groups; so to serve as a private gathering space.

My intended spot for installation will be supported by four large trees; each with diameter more or less by 40 cm, and at least 8 meters high. It will be viewing the south to the old gully tree. >>
