"Clemson University - 3CT"
(4th place overall; 5th in paper; 5th in presentation; 8th in product)

Presentation:

3CT stepped up to the stage and began their story of  “Cast Away.”  Four male and one  female team member gave the presentation.  The team employed a split screen (one showing fixed frames and the other showing video) to promote their effort.

While team members made plans to leave the island, they elaborated on the hull design and explained the concrete properties and the materials used to reinforce their boat.  The steps taken during form construction were described followed by the methods used to construct the boat.  The curing process and finishing tests were described and the person hours given.  After an announcement that it was nine months later, the team made it home... at last.     

 The judges began by asking why was tensile strength important?  How did you measure shrinkage in your concrete and how much was it?  How did you select the aggregates used in your mix design?  

Is their anything that you would do differently if you could do it again?  How was the pre-tensioning controlled during construction and how was it taken into account during your analysis?  What was the rationale used to select fresh water and what would the implications be if you used salt water?  How was the factor of safety selected and determined?  How would you have performed a simple structural analysis if only paper and pen were available?  Can you elaborate on the symbols used in you logo? 

The team designed some good graphics and, in my opinion, this was a very strong presentation.
