COMPETITION DESCRIPTION
The National Concrete Canoe Competition (NCCC) is a competition held every year by the American Society of Civil Engineers. All teams participating in the United States competition are split into regions, and first must compete there. The competition consists of a presentation, engineering notebook, design paper, display, and a set of canoe races. Team participating fabricate a concrete canoe following the guidelines set out by ASCE (can be found on the NCCC Website). This is then through the various competitions described above, and the winner is the team with the most points at the end of all competitions. 

Drexel University's Concrete Canoe Team (CCT) performs research on concrete mix design and fabricates a concrete canoe every year. Mix design research includes finding different types of cementitious mixes, aggregates, and accelerants that will produce a lightweight, yet strong canoe that is able to maneuver through water. Since 2013, Drexel's CCT has moved away from a hand-placed fabrication style to using High Volume, Low Pressure (HVLP) sprayers for a shotcrete application. Switching to this method allows for a more homogenous canoe, which is able to be fabricated in a fraction of the time in comparison to the fabrication of a hand-placed canoe. The shotcrete application does require a different style of mix since it must be able to be shot from a spray gun, meaning that large sized aggregates cannot be used and the mix must be less viscous.

The Drexel CCT competes in the National Concrete Canoe Competition (NCCC) each year, placing 1st at regionals, 1st in the national design paper, and 10th overall at nationals in the spring and summer of 2014.

MY CONTRIBUTION TO THE PROJECT
For the 2013-2014 concrete canoe season, I was a paddler, presenter and write for the Meade technical paper and presentation, and on the spraying team for concrete canoe fabrication process. As a paddler, I went to paddling practices on Sunday's for a few months before the competition, and paddled at both the regional and national competition for the endurance race. A picture of me paddling for national can be seen below. For the Meade technical paper and presentation, I had to write about the responsibilities of a civil engineer for natural disasters, and what measures in respect to standards, regulations, and prevention methods can be done regarding this problem. At the regional competition at the Naval Academy, I presented my idea to the grading committee as well as 100 other attendees. As a member of the spraying team, my responsibility was to help the sprayers reloading their HVLP sprayers with loading concrete.
