The Eden Hall Campus is situated on 388 acres in Gibsonia, Pennsylvania. Originally a farm and retreat for working women of Pittsburgh, Eden Hall was gifted to Chatham University in 2009 by the Eden Hall Foundation. The 20- to 25-year development plan for the residential campus calls for it to be self-sustaining in every way; housing 1,500 students, achieving zero carbon emissions, producing more energy than it consumes, and managing all stormwater and wastewater on site.
University president Esther Barazzone proclaimed that “… Eden Hall [would] be the first community in the world built from ‘below the ground up’ for the study of sustainable living, learning, and development.”
Critical to realizing this endeavor has been the management of that which falls on the ground from above. Unique to the project was the implementation of a decentralized “treat it where it falls” approach to stormwater, preventing any singular large concentration of runoff. The stormwater management system is comprised of a series of separate rain gardens strategically placed around the site to manage small individual drainage areas. Each rain garden discharges excess water over a concrete level spreader to further mitigate concentrated runoff. Captured roof runoff is connected to a 50,000-gallon underground retention tank and later reused for landscape irrigation. Stormwater is also infiltrated into the north parking lot by using a permeable surface and underground stone infiltration beds.
Stormwater is not the only source for reuse applications. A biological wastewater treatment system is utilized for sanitary sewer waste produced by the campus. This system includes a series of primary treatment tanks at each building and secondary treatment consisting of a trickling filter, subsurface wetlands, a sand filter for polishing, and UV filter disinfection.
The primary tanks dose effluent to a trickling filter for nitrification. This effluent is then directed into two subsurface constructed wetland cells. Treated water is stored for reuse as flushing water in campus buildings. Any excess water is safely disposed of via an underground drip irrigation system. The treated water is also connected to a campus greenhouse for use in limited applications.
The overall system allows for extended contact times for the effluent at each stage of treatment. This increases the effectiveness of treatment and overall water quality. The system is designed to be expandable by simply adding additional wetland cells as needed.
The incorporation of these best-management-practice approaches has enabled Eden Hall to meet its project goal of having no point discharges from the developed site. The Eden Hall Campus masterplan allows for flexibility in design and engineering solutions so that future technologies can be integrated into the existing infrastructure. The campus acts as a living laboratory for sustainable design and operations.

Mr. Gregory Rumbaugh, M.Sc., P.E., M. ASCE, is the ASCE-PGH 2015 Government Engineer of the Year. “The award is really a testament to the endless opportunities to be involved with the organization, whether it is at the section-level, technical institutes, Student Award Foundation, or Younger Member Forum,” says Greg. “It is also reflection on the caliber of the mentors that I’ve been fortunate enough have throughout my career, working in both the federal government and in private industry.”
“Greg is truly deserving of this award,” says colleague Angela Mayer. “I am confident that he will continue to serve as a role model for other young Civil Engineers in the greater Pittsburgh area.”
Greg has been active with ASCE and the Geo-Institute since his graduation from the University of Pittsburgh with his B.S. in Civil Engineering in 2006. He subsequently earned his M.S. in Engineering Management from Robert Morris University in 2012. Greg is currently a Civil Engineer with the Department of Labor in the Mine Safety and Health Administration (MSHA) in Pittsburgh.
“I’ve been fortunate in my career with the agency to have the opportunity to work with both surface and underground mine operators extracting various products such as coal, ores, and aggregates,” he explains. “The most enjoyable part of the job is working with our technical or enforcement personnel, in conjunction with mining engineers in the industry, to solve difficult ground control issues.”
Greg has demonstrated noteworthy performance and meritorious achievement as demonstrated by his selection in 2013, and again in 2014, for the “Certificate of Excellence for Historic Achievement” presented by the U.S. Secretary of Labor for Mine Safety and Health. He was also recognized as the 2013 Outstanding Young Engineer in the Public Sector by ASCE’s Eastern Region Council.
“Greg is a very matter-of-fact person with a sense of humor,” say Ms. Mayer. “When working with Greg, he creates an open environment where he injects humor with work.”
While in college, Greg was the University of Pittsburgh ASCE Student Chapter President and remained involved with ASCE following graduation through the YMF, GI, and ASCE Section. He was chair of the YMF Technical Committee for five years where he organized numerous presentations on such topics as networking, financial management, and leadership for younger engineers.
He also organized the YMFs first Mock Interview Workshop Session in 2012. This Workshop, held at the University of Pittsburgh, provided Junior and Senior engineering students the opportunity to practice their interviewing skills with several practicing engineers. “I don’t think I realized the impact that these workshops would have with students at the time we were organizing them,” he says. It was later recognized by ASCE National as one of the best practices by an ASCE organization. “Only after [the event], and through the feedback from the students, did we get a sense for how beneficial these types of events were for the students involved,” says Greg. “I think the students that attended the event were able to leave with more confidence in their ability to interview with prospective employers.”
Greg is currently serving as Vice Chair of the Geo-Institute. Greg has attended numerous ASCE sponsored conferences including the National Convention and the Eastern Regional Younger Members Council (ERYMC) as a Pittsburgh Section Representative. He also works with the Student Award Foundation (SAF) as a past Trustee and Treasurer. “The Student Award Foundation is one of the most worthwhile causes I have had the opportunity to be involved with in our industry. Each year, the group manages to recognize students that either reside or attend colleges within the Pittsburgh Section’s area,” explains Greg. “The most enjoyable part of working with the SAF is participating in the selection of each year’s awards. I am amazed at the achievements and ambition of the civil engineering students in the Pittsburgh area.”

Congratulations Daniel Moore, the 2015 recipient of ASCE-Pittsburgh’s Journalism Award. “As a journalist, it's an honor to receive recognition from an organization of experts,” says Daniel. “The award to me is recognition that I was not only able to appeal to a broad readership but also successful in reaching the people who are immersed in the topic on a daily basis.”
Daniel grew up in the hills of southern Ohio and graduated with a journalism degree from Kent State University in 2014. He has previously interned at the Spokane Spokesman-Review in Washington State, the Student Press Law Center in Washington, D.C., and the Lexington Herald-Leader in Kentucky.
Currently, Daniel covers energy, transportation and labor for the Pittsburgh Post-Gazette. He’s written a wide range of stories about infrastructure, including how the power grid will evolve to meet environmental regulations, how different cities approach sewer overflows, and how railroad track inspections can improve.
“I'm most proud of my story on how railroad track is inspected and how inspectors are sometimes pushed to do quicker inspections when rail traffic is heavy,” Daniel explains. “As we've seen across the country, a missed rail defect is a matter of life-and-death when it comes to derailments of crude oil trains. I analyzed federal accident data and found track defects were the most common cause of derailments. I then spent weeks gathering track inspector sources– on- and off-the-record –who could verify some of the on-the-ground issues, such as arguing with dispatchers about the need to inspect a section of rail.”
Many journalists would consider such research a tedious task. However, Daniel is willing to put in the effort to breakdown the complexities of everyday infrastructure challenges.
“Infrastructure is so ubiquitous that it's largely overlooked. Some people even think it's boring,” he says. “But that is precisely why I think it's important to bring to the public consciousness. For example, people may see trains carrying crude oil when they go to work every day, but what are the track inspectors doing to ensure safe transport? And what are the business models driving how many oil trains are put on the tracks? These things are critically important to being an informed citizen because it affects everyone.”
Of course, learning about the details of an engineering complication is never easy, and to break it down into article for the public is even harder. Says Daniel, “The biggest challenge for me is, quite frankly, learning the science behind the stories enough to write it in a broadly appealing way. Of course, that's also what makes my job fun. I always try to have someone walk me through a piece of infrastructure or technology in person so that I can pull visual details and get an idea of scale. That way I can describe it in terms readers can understand.”
The Pittsburgh Section of ASCE will also be nominating Daniel for the National ASCE Excellence in Journalism Award in September. Since 1994, this award is presented annually at the Outstanding Projects and Leaders (OPAL) Award Gala in Washington, D.C. in March. The award honors newspaper journalists for outstanding articles that enhance public understanding of the role and impact of civil engineering in designing solutions for clean water, transportation, the environment, and other public works projects. In 2006, the award was expanded to include journalists and producers from English-language, general-interest regional and national newspapers, radio and television stations, magazines, and electronic and Web-based news outlets.
The news media wield tremendous impact on public opinion about civil engineers and civil-engineering-related issues. For example, news coverage can influence vital infrastructure legislation, licensing laws and building codes. Coverage also can affect talented young people's decisions to pursue careers in civil engineering.
Through this annual national award, ASCE hopes to encourage continued coverage of civil engineering and related issues as a means of engaging the public in civil engineering initiatives impacting their community.
The Pittsburgh Section is proud that Jon Schmitz from the Pittsburgh Post-Gazette won the ASCE Excellence in Journalism Award in 2012, and is proud to nominate Daniel Moore for the prestigious award this year.

The University of Pittsburgh American Society of Civil Engineers Student Chapter has had another successful year competing at the Ohio Valley Student Conference. This year, 47 students and 3 faculty advisors from the Swanson School of Engineering Civil & Environmental Engineering Department attended the student conference hosted by Cincinnati State Technical and Community College. This year’s conference was held across the Ohio border in the charming town of Lawrenceburg, Indiana during the first weekend of April. Students from 14 schools located throughout Ohio, Kentucky, and Western Pennsylvania participated at this year’s conference. Many aspects of this conference allowed us to take technical knowledge from the classroom and apply it to real-world situations - and we had a great time building camaraderie while doing that!
Without a doubt, the Pitt Concrete Canoe team made the most progress since last year. After passing a swamp test, this year’s patriotic-themed canoe (nicknamed Ol’ Glory) floated to some exciting finishes. Even after some injuries, Pitt was able to come in first place during our heats for the women’s sprint and co-ed sprint races. Finding other unconventional uses for building materials, we also participated in the Concrete Baseball Bat and Concrete Bowling Ball competitions.
After a trip to the Steel Bridge National Competition in 2015, the Pitt Steel Bridge team faced a significant amount of adversity prior to this year’s regional conference. Due to unforeseen conditions at our fabrication facility, it was unclear whether we would even be able to successfully compete at this year’s conference. However, our dedicated students were ultimately able to safely and effectively design, fabricate, and construct our bridge at this year’s regional competition.
Most awarded of all of our competition teams, the Environmental Team earned a 1st Place Overall Award. Additionally, the superb water filtration treatment system designed by Pitt students was given the 1st Place Award for Most Sustainable Apparatus, the 3rd Place Award for Most Creative Apparatus, the 3rd Place Award for Best Technical Review Paper, and the 3rd Place Award for Best Poster Display.
Furthermore, with the support of our unique professor Dr. Budny, the Surveying Team measured up for the 1st Place Surveying Award. An innovative housing plan design and a quality change order completion yielded a 3rd Place Civil Site Design Competition Award. Due to all of these successes and also due in part to our participation in the Balsa Wood Bridge Competition, the Geotechnical Competition, and the Technical Paper Presentation, Pitt ASCE took home the 3rd Place Overall Conference Award. This accomplishment made the long bus ride back to Pittsburgh seem much more enjoyable!
I would like to take this opportunity to thank everyone involved with each of the competition teams for their months of hard work and perseverance. Best wishes to everyone competing next year and carrying on traditions of excellence at the 2017 Ohio Valley Student Conference.

The South Junction Interchange project, designed by HDR (prime consultant) and constructed by Golden Triangle Construction (prime contractor), was an integral part of PennDOT District 12-0’s ongoing initiatives to make safety and capacity improvements to the entire I-70/I-79 corridor.
The project’s primary safety improvement was the elimination of the previous substandard loop ramp that was used to maintain the I-79 northbound movement. This loop ramp contributed to many significant accidents over many decades – and was the primary reason that Reader’s Digest Magazine once labeled the South Junction Interchange as one of the seven most hazardous interchanges in the United States.
The elimination of the previous substandard loop ramp by way of the new high-speed flyover eliminated the need for unassuming drivers to reduce traveling speeds from in excess of 60 mph hour to 20 mph just to maintain travel on the I-79 northbound direction. Through the reconfiguration of this ramp, the South Junction interchange no longer requires appreciable reductions in speed in order to maintain the continuous northbound I-79 movement. It is much more aligned with driver expectations, and, consequently, a much safer facility through which to travel.
During the construction phase, Golden Triangle, in collaboration with their construction engineering partner Mackin Engineering, conceived the innovative idea of constructing a tunnel underneath the existing I-70 overpass structures that would maintain the ramp traffic without disrupting the four lanes of I-70 traffic.
Since the tunnel would be continuous and much wider than the old bridge decks, there would be enough room to shift I-70 traffic lanes from side to side in order to completely remove the old superstructures and rebuild the interstate without the use of conventional temporary median crossovers. Golden Triangle’s outside-the-box innovation saved over $1 million in construction costs – and improved work zone traffic control safety by eliminating the need for high-speed median cross-overs within a curved portion of the I-70 interstate.
PennDOT District 12-0 staff worked very closely with designer and contractor throughout all phases of the South Junction project delivery to ensure a much needed, cost-effective, and innovative improvement to this Washington County transportation facility.

At 12,000 feet above sea level, a three-hour drive from the city of Quito will take you to the small village of Curingue, Ecuador. This village is a one-hour minimum hike away from the nearest water source. This community of approximately 150 members works hard to feed their families through household farms. A small government stipend pays for household water but it must be fetched by walking the hour distance, each way, on mountainous terrain to a spring.
This long trip take a significant portion of the villager’s time each week. But even more alarming, Engineers Without Borders - Pittsburgh Professional Chapter (EWB-PPC) discovered the spring water to be unfit for consumption, as it was contaminated with harmful bacteria. The spring water continually causes a number of health problems for many people in Curingue. EWB-PPC is determined to reduce the community’s time spend collecting water and to provide the community of Curingue with a readily available, uncontaminated source of drinking water.
In 2014, a group from EWB-PPC traveled to Curinque to explore solutions. A group returned in 2015 for another assessment trip before the finalizing designs to build two groundwater intakes, two pumps, a pipeline, and two pump houses. The pipeline will bring water from the spring to Curinque, and the two pump houses will sit along the pipeline path, near the town. At the first pump house, the water will be treated through chlorination. Once the water reaches the second pump house, it will go through a clear house and be pumped the remainder of the way to a storage tank near Curingue.
The design plan has been approved by EWB-USA and the Pittsburgh Professionals will be traveling for the first implementation trip in June 2016.
The community of Curinque has also been preparing for the project and will continue to work on the pipeline and other features between the next two trips. Future trips are tentatively scheduled for fall 2016 and early spring 2017.
