Notes for Bridge Competition

Planing
- Need to be prepare at the early sem or at least 2 months before.
- Design
* Can design base on aims, such as aiming the price. However it is not advisible, because this
will restrain the other aspect.
* To get the lightest, can choose a big arch type where the deck will at the lowest point as a
horizontal movement restrain member.
* To get the creativity, this maybe can be done by creating a landmark or a new type bridge.
However, this do not have a judge point.
* In our case, creativity and buildability is come togather, hence, we win the price because of
our bridge is design base on the real stuation.
* To be share, we are sugested to think our bridge design without consider the difficulty
come during construction.
* If your deck is place high, design your bridge with higher thickness in the center, so that
increase the strength of the bridge. No need worry about the weight, that can be done
by punching hole is your wood layer or refer to advisor.
- the proposal need to pass to advisor, so that can make some adjustment before the design been
firm and can make sure the proposal is complete with no error.

Modelling
- Not to follow the result of shortlist, model it, so that you have enough time to modify after that,
or at least built one for yourself.
- There are lot type of balsa wood, think about the construction need, and also the rules and
regulations.
- Arch constuction
* Cut it in correct span and bend a little bit, span depends on the arch size.
* To get the correct span, this can be done by drawing in a real size, or better is draw in
autocad and print it in 1:1 size.
* For autocad drawing, it is advisible to draw out the wood layering, this can make your
drawing clearer,
- Becareful with base consturction, make it stable as you can. Howeever, it is not just affected by
the base construction, it also depends on the deck that joint after that. Study for your
experience,
- There are lot type of glue, however, eposy not always be the best choice. Choose the one that
suit you most. For example, we using 3 seconds glue to make sure it joint faster but it will be
absorbed by wood. This might increase the weight, however, it is not significant for us.
- Be prepare, cause you not going to get all the thing done by one model.

Multimedia
- Mostly, google sketchup is been used, because of it is easier to handle than any other software,
- However, there still got other 3D software, like autodesk product. But it took us long time to
learn and difficult to use since we not that familiar with it. However, it is good to learn
something new, cause we going to use some autodesk product after we graduate, it can be one
of our advantage to apply job.

Competition
- Prepare your landscape and booth design before going to competition. For us, the table at booth
is around 2m and the booth length just slightly longer than it.
- Treat everyone as your customer, this might help you in presentation, as you pratice it to
them. However, you need to study your bridge much, because you not going to tell other your
weakness, but still need be prepare for other good observation.
- What we notice is, there are some judge came before the judgement, and act like normal
lecturer in their school. If you willing to talk, there might be another advantage for you.
- During the judgement, there might be a lot of question that came from judge and it might out of
your expectition. However, not to panic, some question is need not to answer, because it is not
related to the competition and you also have not much time to do the thing as their question
mention about,

Advice
Competition is a chance for you to learn, price is not important, however, is better if can get it, but the most important is the experience gain during the process. Learn to apply what have you experience before, treat is as a mini project in your education life, Remember to enjoy during the competition, go around and have a look, you can learn more by other bridge also.
