Design and Build Exercise

Thursday February 11

The task of each team is to design a free standing frame made of newspaper, in which the entire team can stand upright together. The frame must enclose the team on all sides as well as above. It does not need to have a floor or walls. The team must be able to enter and exit the intact structure.

Each team will have 10 full-sized sheets of newspaper per team member, plus 10"e; of masking tape for each team member. If you forgot to bring your ten shees of newspaper, I will have some extra.

You may not talk to anyone who is not on your team.

By the end of this class, each team must give me construction drawings and instructions for their structure. The build instructions must be written on official RPD Design/Build forms. The team letter, team member names, page number and section letter must be written on every sheet. The instructions and drawings, plus the unused newspaper and masking tape, must be sufficient to construct the structure as designed. Any newspaper that has been used to construct prototypes, if it cannot be returned to its original flat folded state, will be recycled immediately.

The construction team will not have rulers, calculators, etc. You can assume that they will have only pens and pencils.

Tuesday February 16

The task of each team is to build the free standing structure designed by another team using their instructions, their remaining newspaper and their remaining tape.

You may not talk to anyone who is not on your team.


Design Team Points
  • Design requirements. All of the members of the design team can stand upright in the structure together. Maximum 25 points. 5 points off for each team member who doesn't fit. 1 point off for each protruding head, arm, or leg.
  • Minimal use of materials. Points awarded in rank order of material use. Maximum 16 points, minimum 6 points.
Construction Team Points
  • Adherence to design intent (i.e. to the drawings and instructions). Maximum 15 points.
  • Improvements to the design. Improvement must be documented and must increase the design team's score. Maximum 10 point bonus.
Points shared by Design and Construction Teams.*
  • Structural integrity, measured by deflection under a gentle push. (Remember that structures have zero degrees of freedom!) Maximum 20 points.
  • Build time. Points awarded in rank order of construction time. Maximum 10 points, minimum 4 points.
  • Aesthetics. 15 points.

*For any particular structure, each team gets half the points for this category. So some of your points for this category will come from the structure you designed and some from the structure you built.
