Mini-pat 1 a bridge to help the community

Over the next six weeks, you will design and build a model of a bridge. To do this, you will work through the different stages of the design process and arrange yourselves into teams.

Week 1

Investigate granny margaret thabang’s problem (60 minutes)

1. In your team, read through the following story.

   

   Rivers offer much-needed water for communities, however typically they’ll conjointly create life tough for folks. for instance, throughout the season, folks from villages on one aspect of a watercourse struggle to urge to the opposite aspect of the watercourse,if there’s no bridge.

   Many of the folks in the KwaNogawu village next to the uThukela watercourse in KwaZulu-Natal work on the opposite aspect of the watercourse. The doctors, banks and outlets that they have to go to are on the opposite aspect.

   School youngsters cross this watercourse to urge to their faculties, and therefore the old got to practise it once a month to gather their government grants from the offices on the opposite aspect.

   Usually, the villagers cross the watercourse on foot, as a result of the closest bridge is incredibly secluded. however throughout the season, once the watercourse is flooding, it becomes terribly dangerous. The water levels ar thus high that it’s tough to urge through it safely, {and the|and therefore the|and conjointly the} villagers have also seen crocodiles within the watercourse. most are afraid of drowning or obtaining attacked by the crocodiles, however they don’t have a alternative and got to undergo the watercourse to urge to the opposite aspect.

2. Write a few sentences to explain the problem the villagers have.

   ---

3. Can you suggest a few ways to help Granny Margaret Thabang cross the river?

   

Investigate structures to solve the problem (60 minutes)

On this page and the next there are drawings of different types of bridges. You learnt about these bridges in Grade 8. Do you remember what the names mean? If you cannot remember, look at your Grade 8 book or ask your teacher to help you.

Different types of bridges use different materials and construction methods, but they all have a similar function.

In your group, discuss some of the advantages and disadvantages of each of the bridges for the community. Think about which parts will help the community, and which parts will not help.

If the bridge is meant to carry cars, it might be too expensive for your tender. Remember that the bridge has to solve the community’s problem. In technology, we call this fit-for-purpose. In this case, it means that your bridge has to be strong and high enough to carry people and not cars. However, your bridge has to be strong enough to withstand floods, which are common in KwaZulu-Natal. Your bridge must also be stable, so that it does not sway and cause old people and children to fall when they walk across. It should have a structure that can span a wide river.

Use the following list to help you to investigate each of the bridges in Figure 5on the previous page. Also bring pictures of bridges to school. You can find photographs of bridges in old newspapers and magazines.

Week 2

Develop rough sketches of ideas (30 minutes)

Draw a rough sketch of your ideas for a bridge to help the community. Use the sketching techniques that you learnt in Grades 7 and 8.

Total [10]

Sketch your ideas here:

Evaluate and adapt your rough sketches (30 minutes)

Your team will now prepare a tender. To start, choose the best design in your team. This means you need to choose one sketch from all the rough sketches. To help you choose, answer the following questions:

If the sketches do not meet these requirements, adapt them until they do.

Draw your adapted sketches in the space on the next page. This is your final solution and it will form the basis of your working drawing.

Make your sketches here:

Design brief with specifications andconstraints (30 minutes)

Write a design brief that explains what you want the structure to do. Your design brief has to list the specifications and constraints for your design. Use the open space below to write your design brief.

Remember that specifications are things that your design must have and constraints are things that your design cannot have. The specifications and the constraints are usually listed in the tender notice.

Specifications could include the following:

• The bridge has to be completed within a certain time.
• The bridge has to be built according to budget, including all labour costs.
• The bridge has to help the community. For example, you can employ local people to work on the bridge and train them while they work on the project. That way, they will have good skills that will help them to find work when this project ends.
• The bridge has to be user-friendly for disabled and older people.

Constraints could include the following:

• Time and cost constraints. For example, the building process should not take longer than a specific amount of time, and should not cost more than a certain amount.
• The bridge cannot exclude wheelchair users.
• The bridge cannot employ more than a certain number of people from another area.
• Women should not be prohibited from working on the project.

Total [10]

Write your design brief in the space below and on the next page:

Draw a flow chart (30 minutes)

Do you remember what a flow chart is? A flow chart is a summary of all the steps you have to follow to plan or make something. It is a visual way to show the steps in a planning or making process.

A flow chart is a summary, so use short sentences or just keywords to write down your steps. Then draw a box around each step and an arrow between the steps.

Look at the example of a flow chart below. Now draw a flow chart of how you will build your bridge. Do this on the next page.

Think of the very first thing you will have to do, and start from there. For example: will you measure the river first; will you buy the materials first; will you train your staff first; or will you draw up your budget first?

You can change your flow chart later when you make the model of your bridge. Engineers and technologists often change their plans while they work on a project.

Week 3

Make working drawings (60 minutes)

Working drawings are guides that show us how to build a specific structure. Make a working drawing of your bridge. It should be drawn to scale and show as much detail as possible.

Each member of your team should make their own first-angle orthographic projection of the bridge, showing the front view, top view and end view.

Each of your drawings should show the measurements of the structure and the scale you have chosen. Use correct line types.

You will need the following equipment:

• 30 °, 60 ° and 90 ° set square,
• a sharp pencil, and
• masking tape to attach your drawing sheet to your drawing board.

Work out a budget (60 minutes)

All projects that cost money need a budget. A budget is a plan that looks at the various costs and how the money will be spent.

When you build the bridge, think about the things that will cost money.For example:

• materials,
• labour,
• designers and engineers,
• equipment that you hire or buy, and
• transport.

Remember that you are a contracting company and want to make a profit. Once you have worked out the other costs, add on an amount for your profit.

There will be other companies who will tender for the job, so keep your costs low to make your tender attractive. However, do not compromise the safety of the bridge or allow it to become unfit for its purpose. Balance the need to make a profit with the need to build a safe bridge.

On the following page, there is an example of a cost table for another bridge. You can use some of the material costs shown in this table when making your own cost table for your bridge design.

Example:

Your own list will be different, because it will depend on the materials you have chosen to use to build your bridge. If you are not completely certain of amounts or lengths, always add on a little extra to your final figure. It is better to have a little left over than to run short.

To help you to work out your costs, speak to a hardware shop owner, a building contractor, or a family member who is knowledgeable in these things. You can also look in the Yellow Pages for suppliers. They will give you information if you tell them about your project. Don’t just make up the costs. You need your budget to be accurate.

Apart from the items on the above list you also have to account for VAT and insurance.
