integral role in helping students develop a design that would
withstand earthquakes.
The earthquake in January 2010 delayed the project, and
with the rainy season beginning each March, the students were
unable to return until November 2010. Then, surveys were conducted, decisions were finalized, and they were ready to lay the
base foundations. The Haitians did the work while the students
finished their fall semester. The students returned in January
2011, and stayed two more weeks for the building of towers to
support the cables. When they left, all it needed was the wood
decking.
With 98 percent of Haiti deforested, finding wood of good
quality was no easy task. And again, they were faced with another rainy season commencing in March.
However, when Capelli returned in early March, along
with the new leadership of Virginia Tech’s chapter of Bridges
to Prosperity, Chris Cooke, Tyler Welsh, Nick Mason, Kelsey
Brandt, and Kin Wong, the Haitians had completed the bridge.
However, the islanders had held off the ribbon cutting and
celebration until the students arrived on March 5 during their
spring break.
Even Mason’s father decided to join the team, telling the
students some people have to wait an entire lifetime to see two
communities come together. He wanted to see what his son
and others had accomplished.
“From now on, the Haitians have a complete sense of ownership. They will make all of the decisions on its upkeep and
maintenance,” Capelli says.
During the dedication, the Haitians responded to a survey
conducted by the students. Questions ranged from demographics of the users of the bridge to what it actually meant to them.
Capelli recalls one Haitian said, “I wish you could open up
my heart and see how happy I am because I can’t describe it.”
“We build bridges, but it is the relationships that we build
that really matter and the true power behind our purpose and
mission,” Capelli summarizes.

ENGINEERING NOW
The importance of seed money
When the Virginia Tech chapter of Bridges for Prosperity needed financial
support for the concrete for the bridge foundations, it solicited funding
from the Virginia Tech Student Engineers’ Council (SEC).
The SEC gave the chapter $5,000, and was one of its largest single donors. “We were a brand-new group with the SEC, and we did not expect
the support. But the SEC gave us so much more than what we could
have expected. We want a long-standing relationship with the SEC and to
give back to them. They really stepped in and stepped up and we could
not have completed the project on time without them,” says Matt Capelli,
of Bridges to Prosperity.
After the installation of the bridge, the Rotary Club’s national chapter
provided a $95,000 grant to the national organization of Bridges to
Prosperity. The caveat: It will provide the successful Virginia Tech chapter
with the money to completely fund two future bridges.

Finding clean water for a Third World hospital
By Lynn Nystrom
Can you imagine a hospital that does not have access to clean water on a regular
basis? Or a medical staff who throw their waste into a pile outside the hospital doors?
Neither can the Virginia Tech student members of Engineers Without Borders (EWB).
So, one of their current four projects is focusing on how to resolve clean water and
sanitation issues for the St. Therese Hospital in Hinche, Haiti. In another project, they
just completed the development of a maintenance and operation plan for a malfunctioning ultraviolet disinfection system for a free health clinic operated by the Virginia College

No carbon footprint for this motorcycle

In a crowded bay inside the Joseph F. Ware Jr. Advanced
Engineering Laboratory is the work of the BOLT (Battery

Engineering seniors building an electric motorcycle for eventual
competition in the Grand Prix event in late 2012. For now, the
bike is mostly a skeletal chassis with wheels and some equipment. The bike’s main body is a 2009 Honda CBR6000RR,
while the fork is from a Kawasaki ZX6R. The pieces were
welded together.
Components—such as the electric motor—sit on a workbench nearby or on shelves in a cabinet. Other senior design
