B.1 Research field Sectioning

The definition of sectioning is too general where it can be interpreted in several meanings, however in Architecture studies, section is basically a portion of a form that is exposed when cut by vertical plane in order to show how construction and interior of that form looks like.

In this case study, sectioning research field is almost about right with the general defintion where a form can be created from multiples section that can be varies gradually with other sections. This kind of form can be achieve with help computational and digital design softwares available.

Basically, what computer does is, it create a particular form by making it has individually sections according to the shaped of the form itself. The amount of individually sections of a form can be adjusted according to one’s preferences and this also means that the arrangement of the sections can be adjust in both vertical or horizontal axis.

One thing that need to be considered in this sectioning system is the selection of material. Some material would be difficult to work with in this sectioning where joint or connection are important to make them rigid and stay in place. Thus, light material, easily connected, cut kind of material would be suitable.

Taking an example of the precedent. One Main in Boston is comprises of two planes, the floor and ceiling which both of which are articulated continuous surfaces inflected by function.

B.2 Case Study 1.0 BanQ, Boston, USA

Designed by Office dA, 2008

BanQ restaurant has one of the unique interior where it use sectioning system for the ceiling as well for the support where columns in the middle of the hall is surve to carry on the fiction and it also come out to be suspended from the ceiling. it can be seen that, the ceiling drifts away from every inside divider and rather seek for its support in suspension from above. Almost running the whole width of the space, each rib of the undulated ceiling is produced using a remarkable bits of three-quarter-inch birch plywood followed together in a situation that compares to a puzzle where just single conceivable area for every unit, defining the continuous member.

These continuous members are attached to the main structural ribs running in opposite direction to the cross section, following both the general ceiling topography and the steel supports of the base building. In order to keep up visual densities of the overall surface as observed from different angles, the spacing between the visible roof ceiling is variable, compressing and releasing.

Summer Pavilion ( AA Driftwood Pavilion) London, 2009

Driftwood comprise of 28 layers of plywood which cover an inner “Kerto” which is a sustainable spruce plywood. Structural framework provided by ecological Finnish timber suppliers FinnForest and adheres to a target of minimal material wastage and it was fabricated in Hooke Park. The process of making this pavillion was focusing on embracing invention, experimentation, new materials and aesthetic intelligence.

B.2 Case Study 1.0 Successful iterations

1.B

Form Complexity Constructability Control -This Iteration is successful because the form itself already show the definition of sectioning in which i think it would be convincing to be build since its only 21 of section cuts that are different in level and curve height .

- Can be easily cut by using a laser cutting technique and just combine them together.

2.D Form Complexity Constructability Control The downward slope of the curve section looks like it represent an opening into something regardless how the orientation of the form which i think it will work for our prototype of Kingfisher nest.

4.D

Form Complexity Constructability Control

The pefect rotation of two curces that goes upward make it look complex. it can be seen that, the form comprised of an individual surface that are attached of top of each other and making the form rotating.

3.F

Form Complexity Constructability Control The most complex form among others which still can be build. it is successful because of the complexity of the form which what im looking for to put it on our group brief, to create a complex surface.

B.3 Case Study 2.0 Webb Bridge, Docklands Vic

Project : Webb Bridge | Architect : Denton Corker Marshal | Year : 2003 Generally , the Webb Bridge is a representation of Koori fishing traps and the gestural stream of the waterway underneath the bridge and that is the reason why the bridge is like very curvy towards the end. The bridge consists of two different segments where the 145m long existing structure and another new bended about 80m long inclined link. The slope takes up level changes and makes a state of landing in the south bank. Both are connected seamlessly, with an accentuation on volume and regulation inside the bended and twisted frame.

The bridge comprised of two main components to the bridge : 1) The deck, belly of pigmented concrete screed on steel beam

2) Containing Basket circular ribs and ovoid hoops that encircle the deck fo the bridge The hoops shifts in width from (5x8.7m) and (4x8.9m) in height. They are developed from steel sections 15x150mm, happening at different focuses along the bridge. These are interconnected by a progression of steel straps 150mm wide.

The steelwork was made in pre-assembled sections and after that they are gathered on a barge that was floated in at high tide.

B.5 Technique : Prototypes

Iteration 3

We chose the iteration 3 because we found that this form can be develop more in term of design where this smoothen the surface, elimiated the sharp edges to make it more like natural shape. The next step is to create a texture so that it wont look to plain and empty on the outside.

Horizontal Roughing :

Parallel Finishing:

6.35mm downcut endmill router bit used to roughly remove bulk from material before Parallel Finishing

Done with 6.35mm ball nose cutter to create smooth scalloped effect (visible in nest hollow interior)

Fabrication Learning Outcomes We understand that putting a textured effect on the exterior will need further planning, as the fabrication technique used for the prototype meant that the scalloped texture did not line up.

We could, however, retain the texture within the interior of the birds nest. This might be beneficial in terms of creating a natural hollow ‘feel’ for the Sacred Kingfisher. 3mm dowel may be used for the final model in order to ensure that the sections are aligned together with ease.

We will need to dress the timber in a non-toxic coat that will allow the timber to withstand the weather conditions.

BAND SAW Trimmed individual pieces from timber sheet with Bandsaw

GLUE UP

Nest hollow sections are then glued together using non-toxic glue. The exterior was sanded due to the bandsaw cut edges looking messy/ causing scalloped pattern to not line up

B.8 Learning Objectives and Outcomes Throughout my process of doing Part B assigment for about 2-3 weeks, i think i can see my ability and understanding towards grasshopper has drastically increase. i have learned so many new knowledge about parametric design via computation especially the defintion and tools of grasshopper that i got mainly from the videos tutorial on LMS as well as from youtube. The reverse engineering task really pushed me to the limit because i spent lot of times to figured out how make the Webb Bridge via grasshopper. Even though i still dont really know how several tool works and how can i identify what to use and what can i produce by using it, i think still can find my way to learn it but it’s going to take some times.

The group work also helped me with the important things such as, how to combines idea and how can we produce something that is going to satisfied all of the group members. i often asked them whenever i was confuse about something and they really helped me quite a lot with grasshopper. We have done many research for out proposal and we will working on it cause we really need to decide the best texture for out prototype.

I believe that we will succeed in this project if we really committed in this subject by doing all the works given and help our group membes whenever they are in needs.

B.8 Appendix : Algorithmic Skectches

Biothing Pavilion Tutorial -I started by using 3 hexagon curve in different sizes -Then i just change the variable available in the defintion and i also change the level of the curve - In order to make it look 3D, I use pipe tool with small radius.

Metaball - i was playing around with this defintion becauseit looks like my research field which is sectioning.

-Basically, i just change these variables of : 1) Populate 2D(N & S)

2) Metaball plane on Z unit

Weaverbird -Since im using weaverbird for my case study 2.0, i really need to know how it works and how can i so i just playing around with a sphere where i change the Count of Populate Geometry, and make - i aslo change the shape of the openings of the sphere and extrude them.

to show height.

i produce something that is complex, e it a little bit thick.
