ASCE/CSCE Canstruction

TDEG decided to building the world’s largest building, Burj Khalifa.   The first problem was figuring out the amounts of cans to be used and what would be used to hold the structure together.   The rules only allow for cardboard tubes, Velcro, tape, rubber bands, nylon string and wire.   After designing the project, and much thought, the team set forth in building with the cans in the front lobby of the office building.   The structure was 10 feet tall and used a total of 644 cans.   Afterwards, all the food cans are donated to local food banks.   TDEG was up against nine other teams and placed third.  Proud of what was a team effort, the team is ready to take on the competition again next year!  To see more about Canstruction click here:
