    Executive Summary

    Embry-Riddle Aeronautical

    University or “The Harvard of the Sky” is

    located in sunny Daytona Beach, six miles

    away from the beach. Embry-Riddle

    Aeronautical University is the world's

    oldest, largest, and most prestigious

    university specializing in aviation and

    aerospace. It is the only fully accredited,

    aviation-oriented university in the world.

    Founded in 1925 in Cincinnati Ohio,

    Embry-Riddle has moved from Cincinnati to

    Miami then finally to Daytona Beach in

    1965. Now 50 years later, Embry-Riddle

    has over 30,000 students at each of its two

    main campuses, Daytona Beach, Florida,

    and Prescott, Arizona, and 150 Worldwide

    Campuses located in the United States,

    Europe, Asia, and the Middle East. On our

    campus in Daytona Beach, the most

    beautiful sunsets occur over our flight line.

    Inspired by the beautiful sunsets, the

    aesthetics lead chose a Hawaiian theme for

    this year’s canoe.

    Housed in the College of

    Engineering is the Civil Engineering

    Department. The Civil Engineering

    Department is one of the smallest

    engineering departments on campus and

    because of that, only three other concrete

    canoes have been made and none of them

    have ever won in a conference. Being at an

    aviation oriented school, past senior design

    projects have been concrete airplanes or

    concrete rockets. This year, however, five

    intelligent individuals came together and

    made the concrete canoe their senior project.

    All of the five students designing and

    building the canoe had a little bit of

    experience with the concrete canoe

    competition. The Project Manager, Mix

    Design Lead and Construction Lead were all

    leaders for the concrete canoe team last year

    that produced Miracle. Still being new to

    the competition, having little resources and a

    very tight budget, the senior design team had

    an uphill battle ahead of them. Knowing the

    mix design from Miracle was not a

    competitive mix, the materials lead used

    new, innovative and sustainable material to

    design a mix that could compete with the

    best schools in the conference. Utilizing

    what they have learned from last year’s

    conference in Tampa, Florida and the

    knowledge they accumulated from other

    schools at the conference, Moe Moe Mano

    was born. At 19’1” and 200 pounds, this is

    the longest, lightest and most impressive

    canoe to ever come out of Embry-Riddle

    Aeronautical University.

    Project Management

    This year, the Concrete Canoe was

    chosen for the Civil Engineering senior

    design project. The team leaders were

    chosen from the most experienced and

    brightest students in the department. In

    August, the project manager, structures lead,

    aesthetics lead, mix design lead and

    construction lead were chosen based on

    which area they excelled in and their

    previous experience and skills. In early

    September, a rough draft schedule was made

    to provide a base line of what needed to be

    accomplished. One thing was missing from

    the rough draft schedule though: the little

    experience and knowledge of the concrete

    canoe competition. There were major

    delays in some components of choosing a

    mix design and constructing the mold

    because setbacks were not included in the

    schedule.

    One of the most important processes

    to the project management of designing a

    canoe is keeping the cost of production low.

    Our senior design class was never given a

    budget, but we were told that the cost of

    building Moe Moe Mano needed to be low.

    In order to keep the cost down, half the

    materials used were found in our Materials

    Lab at Embry-Riddle. A wooden mold was

    also used instead of a foam mold, which cut

    the cost by $2000.

    Using the rough draft schedule, a

    critical path was determined. The critical

    path included completion of the following:

    mix design, AutoCAD drawing, construction

    of the mold and casting day. With the

    original schedule, there was an allowe
