A bit about me....
Do you know what a
civil engineer is?
What do you need to do that?
• To be good at Maths and Science
• To have Maths and Science Qualifications
• Either go to university or….
• Do a modern apprenticeship
• To enjoy problem solving
• To want an exciting career!
So, what do I
actually do??
A quick look at
bridge engineering…
From the wooden suspension bridge…
…to the vision of architecture and engineering combined

Some engineering principles
Tension = being stretched
Compression = being squashed
In a triangle:
in compression
in compression
The corners are trying to slide
apart, so the bottom of the triangle
is in tension
In a truss•Tension is blue
•Compression is red
•Some are better in tension than in
compression (think about an elastic band)
•Some are the other way around (like stone
and concrete)
•You will have to experiment.
The Contest
Design a bridge!
Design a truss bridge to carry a two-lane
highway across this river valley
• Ensure that your bridge can
carry its own weight, plus the
weight of a standard truck loading
• Keep the cost of the project as
low as possible
•See Instruction Sheets!
•Download software from the internet
•Register your team of two online - fill in
the local contest code
•Use the wizard to get you started
Some Rules
•Work in teams of two- you must not register
multiple teams
•Submit your entry to the website by the
deadline date and time
•Cheapest design that can carry the lorry will
be the winner!
•The global contest rules on the Westpoint
Bridge website apply
