BUILD A BRIDGE.
Project
You will be building a fixed bridge using only cardboard, and white glue. Your goal is to build a bridge that can bear as much weight as possible. Try to achieve a balance of strength, and beauty, in the design of your bridge. During the final critique, your projects will be strength-tested. Each bridge must hold a minimum of 50 lbs. You will do your best to achieve a balance of strength, and beauty, in the design of YOUR bridge. !
Specs
Materials- You may only use corrugated cardboard. You may only use white glue (Elmer's glue). You man not use hot glue, epoxy, or tape.
Length and Span- Your bridge must be to span EXACTLY 24" (inch). The tables will be secured at exactly 24" apart. Note: The span is the part of the bridge that is not supported by anything beneath it (like the table, leg, or chair). Keep in mind that there will need to be additional length in order for the ends of the bridge to rest on the table top. Therefore, the bridge has to be longer than 24" (inches).
Width and Height- The bridge must have width of 8" (inches). We will be placing bags of clay on the TOP MIDDLE of your bridge.
Lastly, the clay needs a solid place to lay. There must be a flat area on the top of the bridge where we can stack weight for the strength test.
Each Bridge will be tested by gradually adding weight until the bridge breaks.
TAKE PHOTOGRAPHS OF YOUR WORK SO YOU CAN EXHIBIT IT DURING
PORTFOLIO REVIEW.
Rubric
Rubric
Your structure must be a model of a bridge. ( no stacks of cardboard no solid bricks of glue)
You will be GRADED on the :
1 Strength of your bridge, your bridge must hold at least 50 lbs.
2 craftsmanship,
3 aesthetic qualities. ( is this an attractive piece of architecture)
4 Sketchbook work
Process
1. Research bridges and bridge building (see below) investigate the architectural principals of weight distribution. Can you implement any architectural design tricks for strengthening the structure?
2. Design - make plans/ drawings of "your" bridge. What are the Asthetic qualities you wish to convey? can you transform function into decoration?
3. Construction - build your bridge according to the plans you have laid out.
3. Construction - build your bridge according to the plans you have laid out.
SKETCH BOOK COMPONENT.
Before each bridge stress test, we will review your sketches designs and research. ( research and design components) You will be required to discuss the methods of architecture you are emulating, specific bridges you investigated and make comparisons between the sketches you prepared and the final sculpture.
DUE : NOV 17th
Research
Also below you will find links to short and long video’s about bridges bridge building the history of bridges and bridge as metaphor. Along with a couple of videos on how to work with foam core ( which an be translated to cardboard)

Student Examples
Below is a video of the critique from three years ago. Pay attention to both the designs of the bridges, and the set-up of the tables. This will help you in designing your bridge appropriately. Note: the pieces of wood screwed to the side of the table extend down 1' (foot). You may have part of your bridge rest against this surface to help distribute stress/weight.
