To construct a free span paper bridge that is capable of supporting a number of weights.  The best score is achieved by total weight supported.

The bridge must be constructed from only paper and tape. Standard 4 pieces A4 paper size up to 80 GSM only can be used. The bridge span must be the A4 paper width.

Once the bridge is qualified, the length of the bridge will be measured. Fail to follow the rules will lead to the disqualification, and the group will score 0 for competition mark.

After the length measurement is taken, the students will begin to stack the load (range of 0.1N, 0.5N, 1.0N, 5.0N weighted) on its load point.  A student must add a load platform size 40mm x 40mm minimum that will be placed horizontally on the top of the bridge in order to support the load. It can be made of paper board or similar material.
