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.

Professor John Brigham is the 2015 ASCE-Pittsburgh Professor of the Year. “I truly love being an educator,” says Dr. Brigham. “So, to know that it is appreciated is a great feeling.”
Dr. Brigham received a BE from Vanderbilt University in 2003, and a MS and Ph.D. in civil and environmental engineering from Cornell University in 2006 and 2008. After his doctorate, he joined the University of Pittsburgh as an assistant professor in the Department of Civil and Environmental Engineering where he was promoted to associate professor in 2015.
Focusing on computational mechanics and inverse problems, Dr. Brigham’s research group is actively involved in a number of diverse projects, including kinematic analysis of the heart for improved diagnosis of cardiovascular disease, novel design concepts and optimal design strategies for smart material morphing structures, and efficient and accurate quantitative nondestructive evaluation algorithms. “One of my newest projects, that is of course very exciting, is to develop the computational tools to design smart material morphing building surface tiles for more energy efficient building envelopes,” he explains.
“Dr. Brigham brings to the CEE Department energy, fresh ideas and a willingness to lead the way in getting initiatives implemented,” says colleague, Dr. Julie Vandenbossche. “He is a great person to collaborate with on projects. You can rely on him for significant contributions and he will always put the needs of the project and the team before his own needs.”
Dr. Brigham researches other fields, such as simulation modeling of nuclear reactor components, estimation of pathological variation in heart mechanics, and evaluation of well-bore cement integrity. He leads the Computational Diagnostic and Inverse Mechanics Group at Swanson School of Engineering at University of Pittsburgh.
As a teacher, Dr. Brigham has focused on courses involving structural analysis and computer aided engineering. “I also enjoy all of my classes,” Dr. Bingham explains. “Right now, Introduction to Structural Analysis is probably my favorite class I am teaching.” Dr. Brigham also teaches the undergraduate class Computer Methods in Engineering, and the graduate classes Fundamentals of Finite Element Methods and Advanced Finite Element Methods.
“I believe that he is one of the most clear, helpful, challenging, and all-around best teachers I have ever had,” says Senior Civil Engineering student, Scott Overacker. “The majority of Pitt civil engineering students agree.”
“Dr. Brigham is one of the best teachers in the Department both in and out of the classroom,” Dr. Vandenbossche adds. “His commitment to the students and his contributions to both the Department and in his field of study are immense. I feel honored to have Dr. Brigham in our Department.”

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.

On Thursday, May 19th at 8:00 AM at the August Wilson Center in downtown Pittsburgh, the Pittsburgh Section of the American Society of Civil Engineers (ASCE), the Pittsburgh Chapter of Environmental and Water Resources Institute (EWRI), and Sustainable Pittsburgh/Champions for Sustainability (C4S) will be hosting its annual day-long Sustainability Conference. Now in its 8th year, the Sustainability Conference has presented cutting edge themes and topics associated with the ever changing topic of sustainability in civil engineering. The very first ASCE-PGH/EWRI/C4S Sustainability Conference in 2008 explored the potential impacts of climate change on regional infrastructure. Since the inaugural conference in 2008, the overall landscape and dialogue relating to climate change has greatly changed. No longer is the dialogue about whether or not climate change may exist or potentially pose a threat to critical infrastructure. The dialogue has now shifted to developing real and tangible infrastructure protection strategies against the impacts climate change while at the same time finding new and innovative ways to reduce greenhouse gas emissions.
According to scientists from many reputable government agencies, including the National Air and Space Administration and the National Oceanic and Atmospheric Administration, there is a weight of evidence indicating that the Earth’s climate is undergoing a change that may have serious future consequences on our lives and infrastructure. In response to these growing concerns, the ASCE national headquarters adopted Policy Statement 360 in 2015 on the impact of climate change on the civil engineering profession. The policy statement reads:
“Civil engineers are responsible for the planning, design, construction, operations and maintenance of physical infrastructures, including buildings, communication facilities, energy generation and distribution facilities, industrial facilities, transportation networks, water resources facilities and urban water systems. These physical infrastructures have long service lives (50 to 100 years) and are expected to remain functional, durable and safe during that time. These facilities are exposed to and are vulnerable to the effects of extreme climate and weather events. Engineering practices and standards associated with these facilities must be revised and enhanced to address climate change to ensure they continue to provide acceptably low risks of failures in functionality, durability and safety over their service lives.”
The above policy statement is definitive in stating that the civil engineer practice and its practitioners have a duty to consider the impacts of climate change. As we go forward with new critical infrastructure projects and upgrades to existing infrastructure, we as civil engineers must consider if climate change may pose a substantial risk to the “functionality, durability, and safety” on the project.
The following is a brief outline of the speakers and topics for 8th Annual Sustainability Conference. To see the full agenda and to register visit the ASCE-PGH website.

ASCE members and guests gathered at the Engineers’ Society of Western Pennsylvania on Thursday, March 17th for a joint dinner meeting of the Geo-Institute and the Environmental and Water Resources Institute. As part of the meeting, Doug Clark, P.E., and Brianne Jacoby, P.G., of Civil and Environmental Consultants presented the lecture “Groundwater Modeling and Settlement Analysis for Closure for of the Little Blue Run CCP Disposal Area.” The presentation covered various aspects of the rigorous design and analysis required to facilitate the closure of a large disposal area for coal combustion products (CCP).
The Little Blue Run (LBR) disposal area is a 900+acre impoundment located in both Beaver County, PA and Hancock County, WV that has been used since 1975 for the disposal of CCP from FirstEnergy’s nearby Bruce Mansfield Generating Station. In 2012, FirstEnergy and PADEP agreed to a cessation of all disposal operations by the end of 2016, along with the development of a closure plan to be completed by 2031. The closure will eliminate disposal pumping and greatly reduce infiltration into the CCP, resulting in a significant drop in the water table. This change in effective stress would likely result in very large settlements that could impact the surface drainage and final cover system both during and following closure. In order to analyze this potential, a detailed groundwater modeling and settlement analysis program was undertaken.
Ms. Jacoby presented the groundwater flow modeling portion of the project, which was performed using MODFLOW-2000, a three-dimensional finite-difference model developed by the USGS. After calibration to the observed groundwater levels, the model was constructed to perform a 250-year analysis of the water table draw-down. It encompassed an area of 27,000 ft by 27,000 ft and extended approximately 400 feet deep. The resulting predicted drop in the groundwater table exceeded 100 feet in some locations, with the greatest amount of draw-down occurring in the areas of the thickest CCP deposits.
Mr. Clark presented the analysis of the ensuring settlement that would occur as a result of the expected drop of the groundwater table. Between 2002 and 2012, CEC undertook five separate subsurface investigations and four laboratory testing programs. The subsurface investigation programs included 38 cone penetration test soundings and 34 borings for undisturbed sampling. The laboratory testing programs included 77 consolidation tests on CCP sample and numerous other tests. The scale and sophistication of the groundwater model allowed for a detailed settlement calculations with over 2,600 discrete points of analysis. The resulting prediction included a maximum settlement of over 30 feet at the location of the thickest CCP deposit, where the draw-down was the highest. The significant grade change as a result of this predicted settlement necessitated major modifications to the post-closure surface drainage system and the final geosynthetic liner cover materials.
The presentation was based on a paper first published for the 2015 World of Coal Ash Conference in Nashville, TN. The Geo-Institute and Environmental and Water Resource Institute Chapters of the ASCE Pittsburgh Section were happy to be able to provide 1.0 PDH for the presentation. This annual joint technical dinner meeting between the two societies also included a social hour and a sit-down dinner.

Thomas Leech, P.E., S.E. is the 2015 ASCE Distinguished Engineer. “This is a humbling experience,” says Tom. “The award could not be possible without the assistance of many dedicated mentors and colleagues, clients who challenge, and the benefit of a superior university education.”
Tom is the (retired) Chief Bridge Engineer of Gannett Fleming, Inc., Adjunct Professor of Civil Engineering of Carnegie Mellon University, and a part of the continuing education faculty of the Pennsylvania State University. During his 48 years at Gannett Fleming, he designed major bridges, tunnels, and highways and conducted forensic studies prior to his retirement. “[I enjoy] the satisfaction of seeing what is visualized and expressed only in pen and paper realized in the form of physical construction, which many can view, but few can appreciate,” Tom says.
“I was fortunate enough to work closely with Tom over the past 5 years,” says colleague, Linda Kaplan. “He is an excellent teacher and mentor, continually breaking complex problems down into simple concepts and basic principles so that they could be easily understood.”
“Tom was not just an engineer,” adds Gannett Fleming Vice President and National Highway Practice Manager, Eric Veydt. “He is creative, always trying something new, always looking for a better way to convey a thought or idea. Simply put, Tom always challenged us and made us better.”
Tom has led various infrastructure design projects throughout Western Pennsylvania, including the Bloomfield Bridge, the Joe Montana Bridges, the Hulton Bridge, the Toll 43 Monongahela River Crossing, the North Shore LRT Viaduct at Allegheny Station, the Fort Pitt and Squirrel Hill Tunnel Rehabilitations, and the forensic evaluation of the collapse of the Kinzua Viaduct. He has published over 50 articles in national and international journals, conference proceedings and magazines, and has delivered numerous presentations at national and international conferences. Tom was also the lead technical author of the Bridges of Pittsburgh Art Mural that is presently displayed at the Greater Pittsburgh International Airport. He recently was the editor of the book Reflections...of the Greatest Engineers and Architects of the 20th and 21st Centuries as well as a contributing author to the Geology of Pittsburgh.
“Tom has instilled in every engineer a wonderment for the science of bridge engineering, an eye for the beauty of bridge aesthetics, and a passion and determination for the problem solving,” says Senior Structural Engineer for Gannett Fleming, Jonathan McHugh.
For the past ten years, Tom has been a magazine editor for ESWP’s Summer Magazine, with each edition focusing on separate and unique topics related to the bridge industry. “Engineers have a story to tell,” he explains. “Writing to peers, the language of precision is necessary, and the nuance of detail is important. Writing to the lay reader interested in science and technology, visualization of concept, human interaction, and conciseness true to the endeavor become the overarching challenges.”
Tom has actively served the American Society of Civil Engineers and the Engineers Society of Western Pennsylvania. “Tom’s leadership through the ESWP – IBC enabled that organization to develop into an internationally recognized association,” says Mr. Veydt. Tom has also been active in the International Bridge Conference Committee, the Association for Bridge Construction and Design, and the Association of Highway Engineers.
“Tom’s influence on the Engineering Profession in the Pittsburgh Area will live on through future generations and his contribution through projects will provide lasting improvements to the region.” Mr. Veydt asserts. “I count it a great privilege to have work under Tom at the start of my career and alongside Tom throughout my career.”

In February 2016, several Pittsburgh ASCE Section members attended the first ever Geotechnical and Structural Engineering Congress, held in Phoenix, AZ. This conference was unique in that it was a joint conference between ASCE’s Structural Engineering Institute and Geotechnical Institutes, marking the 20th anniversary of the founding of each. This combination provided the opportunity for topics and discussions on how the two civil engineering disciplines interact and what can be done professionally to increase collaboration between the fields.
The conference opened with a lively panel discussion about the interaction between the two disciplines, titled: “Soil is Not a Spring, Buildings are Not a Load.” Three representatives from each Institute discussed issues with collaboration in design. Discussions included degrees of uncertainty in geotechnical capacities vs. structural loads and how to ensure we’re not unknowingly over-designing, and questions of responsibility for the final product including a debate about whose professional seal should stamp foundation drawings or that they should be jointly sealed. The differences in work flow between private (primarily buildings) projects where the structural and geotechnical engineer are often hired separately by the client, and public (primarily transportation) projects where the geotechnical and structural engineer are likely to be working for the same firm, or one as a sub of the other, was also a major point of discussion.
The conference included 15 technical tracks with presentations on a variety of technical and professional issues in the structural and geotechnical fields. One discussion stood out, related to professional licensure and the attempt by some states to remove the requirement for Professional Engineering licensure for structural design. This debate lead to comments as to how the profession could protect itself from lawsuits due to incompetent individuals designing projects, and the public image of losing the expectation of structures to not fail. Additionally, another discussion spurred from the occurrence in some states that require an S.E. license for certain structures and how that doesn’t allow a geotechnical engineer with a P.E. to design foundations and retaining wall systems in that state, yet they have the ability to design those same structures in other states.
Nine members of the Pittsburgh Section attended. Two members, Greg Holbrook, P.E. of CDM Smith, and Don Cunningham, P.E., of HDR, were able to attend the conference courtesy of SEI Young Professionals Scholarships. This competitive scholarship program is offered annually by the SEI Young Professionals Committee to allow 10 younger members who would otherwise not have the opportunity, to attend. Additionally, Don Splitstone, P.E. and Bruce Roth, P.E., both of GAI, attended to present their paper “Micropiles Ease Historic Bridge Replacement”; Linda Kaplan, P.E., of TRC, and Greg Braun, P.E. of Gannett Fleming, attended and presented “Geotechnical and Structural Engineering Collaboration on a Large Scale Bridge Project: A Case Study of the Hulton Bridge”; Jonathan McHugh, P.E., of Gannett Fleming presented “PHX Sky Train Phase 1 – The Interaction of Structural and Geotechnical Design Considerations”; Dick Gray, P.E., and Robert Hanna, P.E., of DiGioia Gray and Associates, attended as well.
Highlighting the conference was a series of special events and receptions.
Following the conclusion of the conference, some of the Pittsburgh Section members got a chance to take advantage of the warm Phoenix weather prior to heading back to Pittsburgh. Greg H., Greg B., Jon, and Linda decided to hike Piestewa Peak (formerly Squaw Peak) to take in the view.

On March 16th more than 200 ASCE members from 49 states descended on Capitol Hill to advocate for infrastructure and the civil engineering community. Armed with their everyday civil engineering experiences, issues briefings from the ASCE Government Relations team, and insight from two keynote speakers. Joining them were three members from the Pittsburgh Section, Nat Hayes, Gabby Briffa and Greg Scott. Fly-In attendees spent Wednesday afternoon advocating for a new Water Resources Development Act (WRDA), water infrastructure funding, and the Federal Aviation Administration Reauthorization (FAA). In her presentation on Tuesday night, Marion McFadden, deputy assistant secretary for grants programs in the United States Department of Housing and Urban Development’s (HUD) Office of Community Planning and Development highlighted Rebuild by Design and HUD’s $1 billion nationwide design competition for infrastructure projects and community programs open to areas affected by natural disaster from 2011-2014. ASCE assisted HUD in the competition this past summer by providing cutting edge engineering expertise in designing resilient infrastructure.
On Wednesday morning, Rep. Garret Graves (R-LA) a member the House Transportation and Infrastructure Committee and a former congressional staffer provided not only insight on the current political climate of infrastructure policy in the House but he also offered tips on how to improve the outcomes of Congressional meetings. ASCE members meet with roughly 230 congressional offices this week, including a visit to every congressional in PA. Don’t forget to add your voice to theirs by sending an email to Congress in support of infrastructure investment.

Tom Batroney, PE, ENV SP, is the ASCE-PGH 2015 Young Engineer of the Year. “The Pittsburgh region has so many impressive civil engineering professionals,” says Tom. “To be recognized amongst a great group of professionals feels good.” Tom is currently a Project Engineer with Hatch Mott MacDonald in Pittsburgh where he works on a variety of environmental and water resources related projects. He received his B.S. in Environmental Engineering from Wilkes University in 2001 and his M.S. in Water Resources Engineering from the University of Villanova in 2007. He obtained his P.E. license in 2012. Tom has demonstrated technical, organizational, and managerial skills that have been recognized by his employer and his clients as outstanding.
“Tom has been an exemplar of a civil engineer ever since he came to Pittsburgh,” says colleague, Gregory Scott. “Besides his professional competency, he has demonstrated his leadership with the EWRI Pittsburgh Chapter and then on a National level with EWRI.”
As a member of ASCE, Tom currently serves as a Director for the Pittsburgh Section’s Board and is the Past Chair of the Pittsburgh Section’s Environmental and Water Resources Institute (EWRI). Tom was a key person in expanding the EWRI’s reach through organizing numerous technical and industry-relevant seminars and conferences. He was instrumental in creating the first EWRI graduate student chapter at Carnegie Mellon University. “Fresh and new ideas are needed in all organizations and businesses,” he explains. “Contributions from EWRI student chapters at Carnegie Mellon and University of Pittsburgh are perfect examples. Motivated and active new members often will stimulate the entire group and spur new ideas that eventually improve ASCE as a whole.”
He continues to provide unselfish contributions to ASCE and EWRI activities, collaborate with other technical groups and institutes, mentor new members, and provide valuable guidance to the Pittsburgh EWRI Student Chapter. More recently, Tom has risen to the challenge of forming and leading the Pittsburgh Section’s Sustainability Committee, addressing one of the Society’s strategic initiatives. “There are tools out there that civil engineers can use to evaluate the sustainability of their projects,” Tom says. “My goal is turn the somewhat nebulous word 'sustainability' into something more clear for engineers to understand how it relates to their projects.”
In addition to these professional achievements, Tom has shown a very strong commitment to various community activities, most notable of which are the Regent Square Gateway Project Team, and the Nine Mile Run Watershed Association.“It was no surprise to me to volunteer for a stream clean up last fall and run into Tom there volunteering along with many local community members,” says Mr. Scott. “He is a terrific person who deeply cares about the environment.”
