Senior Design, Fall 2018
At the end of each year, it is appropriate that
we pause and reflect upon “the big picture” – the state of our nation and the
world. Lots of things currently, especially the schism between the extremes in
our society, encourage a pessimistic view of our future. Fortunately, however,
my continued contact with the young people in the Civil and Environmental Engineering
Department at the University of Pittsburgh provides me with a lot of reasons to
resist that temptation.
In the last semester before they graduate our
students participate in our Senior Design Projects program, a program that I am
privileged to coordinate. In this program they implement “near-real-world”
civil engineering projects in a cooperative team environment. This semester we
had forty-two students representing six different specializations organized
into six teams.
The culmination of the semester’s work is a
formal presentation to an audience made up of fellow students, faculty, family,
friends, and representatives of local engineering firms. It was made in the
ballroom of the O’Hara Student Center in an environment that replicated a major
“real-world” public meeting. Each team was “on stage” for about forty–five
minutes, followed by a ten-minute comment and question period involving the
audience. The poise and obvious competence of all of the students was
particularly impressive.
The first project focused on sustainability. Civil
Engineers traditionally have been concerned with infrastructure design that is
consistent with the long-term health of our environment, with special emphasis
on energy and water. In recent years this concern has been formalized and is a
fundamental part of our curriculum. This team set out to demonstrate
quantitatively the application of these principles to a practical project.
Their goal was to design a facility to
demonstrate sustainability, somewhat similar to the Center for Sustainable
Landscapes at Phipps Conservatory. Their site was a 40-acre agricultural
property in Butler County. They designed a “Net-Zero” facility which would
generate electricity by a combination of solar panels and wind turbines and
have self-contained water supply and waste disposal systems. The main feature
in the facility is a large two story public building designed to minimize
heating and cooling requirements. It was an excellent example of the
application of qualitative principles to a practical example.
The second project involved a team made up
primarily of construction management students. Our department is quite proud of
this program, which was initiated twenty years ago in response to numerous
requests from local construction firms for engineers with the special
capability of managing construction projects. Its graduates are doing highly
responsible work all across the country.
This team chose to develop a comprehensive plan
for the construction of a hypothetical 600 vehicle parking garage to be built
on a specific site on the University campus. The garage was designed to be constructed
using precast, prestressed concrete components, a technology that initially was
unfamiliar to the students. The product of their work was extremely impressive;
one practitioner in the audience commented that they had demonstrated all the
skills an actual construction management firm would be expected to exhibit.
The third project came very close to being a
“real world” one. Upper St. Clair Township is in the early stages of planning a
hiking/biking trail connecting Boyce Mayview Park with the Montour Trail. Our
team expanded this concept to include Fairview Park and the planned Hastings development
on the site of what was Mayview Hospital, both of which are in South Fayette
Township.
Their design resulted in a trail that would
serve the needs of both townships. The trail winds along Chartiers Creek,
providing an attractive venue for casual walkers and nature lovers, as well as
a link to the Montour Trail for serious cyclists. A representative of Upper St.
Clair attended the presentation and commented that their report would certainly
influence the next phase of their deliberations. The development of trails of
this type has become a significant area of interest for civil engineers.
The fourth team accepted the challenge of
independently developing a design and construction management plan for a real
project that was implemented this Fall. In October the Pennsylvania Turnpike
was shut down for fifty five hours one weekend to permit the demolition and
replacement of a major bridge, a remarkable feat that was accomplished “without
a hitch”. One of the engineers involved in this achievement is also an Adjunct
Professor in our Construction Management program; he provided our team with
sufficient background information and mentored them during their design effort.
The team designed a two-span continuous steel
plate girder bridge, to be erected adjacent to the existing bridge, and then
developed a plan to demolish the existing bridge and then slide the new bridge
into place using Teflon slide plates. The team’s bridge design and
implementation plan were not identical to their actual counterparts, but were
quite appropriate alternatives, according to their mentor.
The fifth team also had a project that was close
to “real-world”. One of our students is aware of a real problem in Volant, his
home town. A very old dam on Neshannock Creek was breached recently and must
either be demolished or replaced. The dam originally provided water for a
turbine driven grist mill, a mill that the local residents would like to see
put back into operation as a tourist attraction. Other complications include
recreational use of the Creek by kayakers and by fly-fishermen.
This is a classic example of an engineering
project with complicated social and economic constraints. Our team met with the
various stakeholders and concluded that the best interests of all parties
concerned would be met by constructing a new dam similar to the original one,
incorporating the useable remnants of the old one. It is our opinion that their
design will function as a feasibility study that will eventually result in its
implementation by a professional engineering firm.
For the past five years a student organization
known as Pitt HEADS has executed a series of humanitarian projects benefiting
disadvantaged people in Latin America, frequently with the support of our
Senior Design Project teams. This semester’s project was an ambitious one, the
installation of solar panels, storage batteries, and a microgrid in an
indigenous village in a rain forest in Panama. Transporting material to this
site required the use of powered canoes and back-packing through the jungle.
A team of construction management students produced
a workable plan for the project, provided the necessary logistics, and
participated in the actual on-site installation. Of equal importance was their
initiation of planning for the phase of this project, based upon their hands-on
experience. Although this project lacked the technical challenge of our typical
projects, the experience of performing a difficult task in a hostile
environment and benefitting needy people provided our students with an
invaluable sense of accomplishment.
I realize that three and a half dozen Civil
Engineering students at the University of Pittsburgh is a tiny sample of all the
young people across our country who are making the transition into adulthood,
but I have a very optimistic view of the future once this generation begins to
influence our society. They are intelligent, well-educated, sensitive to the
needs of people lacking their advantages, and committed to preserving our
environment for the benefit of future generations. I am sure we are leaving our
future in good hands.
