Unit question: What makes a designer successful?

Introduction:The stunning landscape of the Wilsons Promontory National Park has been changed

substantially as a result of the flash floods and landslips after 370mm of rain fell in 24 hours

this week. Dozens of trees have been uprooted, washed away and now lie bundled together

like matchsticks.

The only access point to the national park, the Darby River Bridge, has collapsed as a result

of the extreme weather.

Helicopter evacuations of the 203 people stranded in the park finished yesterday afternoon.

The local police officer said it had been important to start the rescue operation soon after

the deluge ended and the destruction was evident. ''We had a number of school kids for astart. And the road is cut off and there's no way out,'' he said. ''We can't leave them there.''

The chief executive of Parks Victoria, Bill Jackson, said the park would be closed indefinitely.

Construction of a new bridge is needed as soon as possible.

We need your help!

DESIGN BRIEF:Parks Victoria has invited your engineering company, to put forward a proposal to design

and build a new bridge over Darby River.

The bridge needs to meet the following requirements:

Budget:

o Parks Victoria has a budget of $75,000for the project. Aesthetics:

o Wilsons Promontory is a national park, popular among tourists for itsbeautiful rainforests, unspoiled beaches and abundant wildlife. The bridge

design needs to reflect the values of the national park.

Building specifications:o The bridge needs to

Span the 20m distance between the river banks (equivalent to 20 cm) Be a two-lane passageway for cars (equivalent to two matchbox cars)

Have a minimum carrying capacity of 15 tonnes (equivalent to 15kg) Time frame:

o The model bridge and pitch must be completed by the due date to beconsidered by Parks Victoria.

PREPARING YOUR PROPOSAL:

Part A: Research (Individual task) OW C

In order to design an appropriate bridge for Wilsons Promontory, you will need to develop

knowledge about the four main types of bridges: Arch, Beam, Suspension & Cable-stayed.Complete a one sided A4 fact Sheet for each of

the four types of bridges.

Each fact sheet will need to include the following:

Description of this type of bridge, themain design features (including a picture).

When does this sort of bridge work best?In what situations would it be suited?

Two examples of this type of bridge (oneAustralian example, one World example)

Part B: Budgeting the bridge design (individual task) C

In your group, design a model bridge that meets the needs of Parks Victorias budgeting and

design needs.

Materials available for your model bridge:

Materials Cost per item ($)

Straws 2,200

Icypole sticks 2,130

String 650

Corrugated cardboard (25cm x 15cm) 20,000

Glue sticks (for hot glue gun) 5,000

Pipe cleaners 2,000

Draw a diagram of your groups bridge design to scale. In presenting your design toParks Victoria, multiple views of your bridge would provide best communication of

the aesthetics (e.g. side view, aerial view, etc).

Based on your design, represent your spending in an appropriate format (e.g. table,column graph, pie graph, etc). Remember to consider your $75,000 budget.

Include all working out.

Your groups budget must be checked and signed by your maths teacher. Your groups design must be checked and signed by your science teacher, Once checked, you may order the equipment needed to complete your model

bridge.

Part C: A scale model of the designed bridge (group task)A

Building your bridge:

Each group will need to keep a record of the steps used to build their bridge. You will need

to video your work in class and this will be used to make an iMovie of your bridge design

process.


4/7

Part D: The pitch to Parks Victoria (iMovie group task)C

Your iMovie will be completed as a group and will be submitted as part of your assessment,

and should not exceed 3 minutes in length.

Your iMovie needs to include the following:

A convincing presentation to Parks Victoria, showing that you have met theirdesign brief

o Budgeto Aestheticso Building specificationso Time frame

The steps involved in the assembly of your bridge The reasons for the choices of materials for each part of your bridge The final model

Part E: Reflection/ Evaluation (individual task)

R

This will be completed in class under test conditions.

Part F: Extended response (Individual task) OWWhat do designers need to consider when building structures, such as bridges in national

parks?

Consider at least two of the following factors in your response: moral, ethical, social,

economic, political, cultural and environmental.
