Presentation:

The University of Puerto Rico Mayaguez represented the Southeast Conference and made their second national appearance.

UPRM relied on 5 people to make their presentation; 2 men and 3 women. The presenters were dressed in formal attire. The team used 1 screen; there were 2 animations.

The team based their theme on a traveling carnival. They began their presentation by elaborating on their theme.

After describing their organizational structure, the team elaborated on hull design. They described their reinforcement scenario and explained why they selected the materials that they did.

The team gave details on post tensioning and the location of the steel elements used to do this. Then, it was on to concrete mix design.

The team described their mix design goals and outlined their test program. They referred to ASTM standards and stated that their mix design fell well within their design envelope.

Then, then team described how they constructed their mold and canoe. They elaborated on the casting process and mentioned that they used a load cell.

The team discussed their safely program and specified the man hours that they spent on the project. They explained they had achieved a significant reduction in the latter.

After outlining the project costs, the team brought their presentation to a strong conclusion.

Questions and Comments:

  • How did you determine the amount of force required to tension your reinforcement?
  • Does the vinyl used to encase your steel cables have to stick to the concrete?
  • Can you describe the quality and quantity assurance procedures that you used throughout the construction process?
  • You used a Type 1 fly ash. What type of ash was this?
  • How did the fly ash lower the concrete density?
  • What was the affect of incorporating the cables into your test specimens?
  • How did you constrain your cables during your test program?
  • How do the sharp "V" shapes in the bow and stern minimize water resistance?
  • How did you prepare your canoe for transportation?
  • Did you consider this condition during your analysis?

Commentary:

The presentation was very informative and entertaining and went off without a hitch. However, the team had some difficulty addressing the questions. Some of this may have been due to miscommunication created by a language barrier, since English is recognized as an official language in Puerto Rico but the native language is Spanish.
