Seventy-four Geo-Institute & Deep Foundation Institute (DFI) members and guests gathered at the Engineers Society of Western Pennsylvania on Saturday, April 8th, 2017 for an ASCE Pittsburgh Section Geo-Institute and DFI Chapter short course. The course was presented by members of the DFI Committee on Augered Cast-in-Place (ACIP) and Drilled Displacement Piles, led by Morgan NeSmith, P.E. (right), presented latest advancements in design methodology, testing, quality control and assurance, and recent case history regarding ACIP piles.
A total of ten presentations were presented during the Saturday short course. Morgan NeSmith, P.E. started off the morning session by introducing the committee projects, the development of ACIP, and current installation procedures. He also talked about their commitment to introduce ACIP and its usefulness to various Department of Transportation entities. Following Mr. NeSmith’s presentation, various DFI Committee members of ACIP piles presented about quality control and assurance, design methodologies, case histories, non-destructive testing, challenges in ACIP construction, grouting, and applications of ACIP. A full list of speakers and their background is available online at ASCE Pittsburgh Geo-Institute web page.
Feedback of the survey handed out during the short course offered us a highly positive response from the attendees. Many attendees were extremely satisfied with the technical presentations offered at the short course while some even said ‘It was one of the best I have ever attended- and I have been to a lot.’
The short course took place from 8am to 5:30pm and included a continental breakfast and lunch. The Geo-Institute & DFI were happy to be able to provide up to 7.5 PDHs, including 6.75 hrs accredited for New York professional engineers.

The Western Pennsylvania ACE Mentoring program introduces interested High School students to various disciplines within the Architecture, Construction, and Engineering fields. The program runs from October to May, with the students meeting every other week. For the first 6 weeks of the program the sessions focus on introducing some of the major ACE fields: architectural design, civil/site engineering, structural engineering, urban planning, MEP engineering, and construction management. ASCE representatives provided the background presentations and activities for both the civil/site engineering and structural engineering sessions in Fall 2016.
For the second half of the program students split into teams to develop the design of a real life local project. Team members will each take on different roles: architect, civil engineer, structural engineer, urban planner, contractor, or mechanical/electrical engineer based on their preference from the first half of the program. Over the course of 4 working sessions the students will meet first with experts representing their assigned project roles to learn more about that field and develop the design. Students will then meet with their teams to coordinate the overall efforts of each discipline. At the end of the program project teams will present their work to a panel of judges and one team will “win” the contract.
This year’s project
In the 1960s, access between two neighborhoods, Downtown Pittsburgh and the Hill District, was severed by the construction of I-579 also known as Crosstown Boulevard. With the demolition of the Civic Arena and construction of PPG Paints Arena, redevelopment of the area aims to help revitalize the Hill District. Part of those plans include reconnecting the Hill District to Downtown by ‘capping’ I-579 to eliminate the physical barrier between the neighborhoods. Restoring the connection between the communities will offer more convenient and safer access to opportunities for residents of the redeveloping Hill District including jobs, education, and connections to other neighborhoods and services. Special thanks to HDR Engineering for sharing project information with the students.
Each team is to develop a concept for the 3-acre (52,800 square foot) project site. The project will consist of the construction of a new structure spanning over a portion of the below-grade I-579 highway, a developed pedestrian and bicycle network, and an urban open space for gathering, along with a building. The students received an RFP that included deliverables from each of the 6 disciplines. This format allowed the interested students to get more in-depth with their chosen discipline than previous years and allowed the mentors to introduce more advanced concepts and realistic material.
ASCE members Linda Kaplan, PE and Karen Mueser, PE led the students of the structural engineering team. These students were responsible for development of the design of the spanning structure over I-579. Students used portions of the AASHTO and AISC code, as well as PennDOT standard templates to develop a Type, Size & Location report for their structure. Their final product included load calculations to size the main members, plan and elevation drawings, as well as a written report.
“Working with a small group of students who had an expressed interest in structural engineering made this one of the more rewarding ACE experiences for me.” Linda observed. “The students worked really hard and we were able to take these concepts further than is typical in a high school mentoring environment.”
Member Nicholle Piper, PE organized the activities for the civil/site engineering group. This group’s deliverables included a site topography plan, stormwater runoff calculations, a site utility plan, and a site plan. The students followed PADEP regulations, City of Pittsburgh code requirements, and a sample zoning ordinance to prepare their deliverables.
The students will be presenting their final projects on May 10th, starting at 5:00 pm at the Carpenters Training Center of Pittsburgh off of the Parkway West. The event is open to the public, and ASCE members are invited and encouraged to attend to see the impressive work of these students, future members of our profession.
Pittsburgh Section ASCE Civil Engineers volunteer to mentor regional high school students. To join them for the 2017-2018 ACE program. please contact Linda Kaplan or Karen Mueser.

A few years ago The Structural Engineering Institute created a “Vision for the Future”, which is the institute's long term strategy to ensure a vibrant and dynamic future for the structural engineering profession. The SEI envisions a future where, as stewards of the built environment, structural engineers will make key contributions to the advancement of society on a global scale. The vision is also for structural engineers to be leaders and innovators that play a critical role in improving the safety and well-being of the global population. To achieve these goals the SEI has established the following key initiatives:
The Structural Engineering Institute also has the SEI Futures Fund, which helps to advance the art, science, and practice of structural engineering. The SEI undertakes a broad range of activities that build a brighter future for our profession, and since some of these activities fall outside the SEI annual budget the Futures Fund was established to provide philanthropic support for these activities from individuals and organizations. The following strategic initiatives were created by the SEI Futures Fund Board:
The 2017 Fundraising effort helped to support SEI’s new Global Activities initiatives to grow SEI global presence through resource workshops, an international practice guide, and increasing international sessions at Structures Congress. The fundraiser also created a new SEI Student Competition and provided scholarships for young professionals to attend Structures Congress. Proposals are currently being accepted for new initiatives.
As a fundraiser for the SEI Futures Fund, CSI (Computers and Structures, Inc.) has hosted a gala event for the past two years at the SEI Structures Congress. This year, the event was at the Denver Art Museum and had hor d'oeuvres, cocktails, live music and door prizes. The event is sponsored in full by CSI and all proceeds for the event go directly to the Futures Fund. The founder and CEO of CSI, Ashraf Habibullah, attended the event and is a proud supporter of the Futures Fund, and big promoter of the structural engineering profession.
I strongly encourage you to consider a donation to the SEI Futures Fund, as it provides the opportunity for our profession to continue to grow and expand to build a vibrant community of structural engineers. You can find out more about the Futures Fund and all of its initiatives at the SEI Futures Fund Website.

More than 55 ASCE members and guests gathered at the Engineers’ Society of Western Pennsylvania on Thursday, March 23rd, 2017 for an ASCE Pittsburgh Section Geo-Institute and Deep Foundation Institute - Women in Deep Foundation (DFI – WiDF) Chapter meeting. Nancy Watt, a communications professional, writer, trainer, speaker and a graduate of Second City Comedy Improv Conservatory in Toronto, presented a lecture on how to enhance an employee’s communication skills for efficiency, integrity, and achievement at all levels of an origination.
Ms. Watt started the presentation discussing the value of noticing gender differences in communication being critically important to stemming the tide of women leaving the geotechnical and foundation industry. Long seen as soft skills, the cost of poor communication inevitably results in increased employee turnover, poor customer service, ineffective change of management, failed project delivery and high litigation costs.
The presentation was orientated around various improvisational activities and discussions between attendees to improve communication, expand women’s mobility in the workplace, and cultivate integrity and achievement in all facets of an organization. It was a very atypical civil engineering gathering. In fact, the speaker pointed out that it was very unusual for the men to be the minority of the group in technical meetings.
The meeting was very interactive with several one-on-one improvised conversation skits and other thought-provoking communication activities engaging all of the participants. Ms. Watt presented a brief discussion of the results to provide feedback regarding body language and other nonverbal communication observations. Congratulations to all of the participants and thank you for your enthusiastic support of the Women in Deep Foundations and the Geo Institute!
The Geo-Institute & DFI-WiDF were happy to provide 1.0 PDH for the presentation along with a great venue for social hour and dinner.

Every spring, ASCE holds its Legislative Fly-In Program in Washington, DC, an intensive two-day program that provides participants with an inside look at the public policy process. On March 15th, while Winter Storm Stella wreaking havoc along much of the Northeast, over 200 ASCE Members representing 49 different states attended the 2017 American Society of Civil Engineers (ASCE) Legislative Fly-In. Many of the attendees were impacted by the storm but still found a way to DC, a testament to their passion for advocacy concerning what they know best.
The 2017 Legislative Fly-in program featured a day and a half of in-depth briefing sessions on the recently released 2017 Infrastructure Report Card, key legislative action in Congress, training on raising awareness and influencing elected leaders, networking with ASCE peers from across the country, a Younger Members Program, and tips on continuing relationships with elected officials after returning home. The program culminated in one-on-one meetings on Capitol Hill with members of Congress and their staff.
The delegation from Pennsylvania included Mr. Jason Bowes, Central PA Section Government Relations Committee Chair and State Advocacy Captain; Mr. Jesse Gormley, Philadelphia Section Member; Mr. Joseph Natale, Philadelphia Section Member; Ms. Adrienne Nikolic, Philadelphia Section Member; Mr. John Caperilla, Lehigh Valley Section Government Relations Committee Chair and Mr. Gregory Scott, Pittsburgh Section Government Relations Committee Chair and Federal Advocacy Captain.
The ASCE Government Relations staff scheduled meetings for each of the attendees with their Senate and Congressional Representatives within a short window on Wednesday afternoon. After being dropped off at Capitol Hill, Team Pennsylvania was off to the races to meet with both Senator’s and every team member’s Representative, as well as other Pennsylvania Representatives with a numerous ASCE member constituents. As the afternoon progressed, the group had an opportunity to engage in spirited and encouraging discussions with staff and Representatives from their home Districts as well as those identified as staff of ‘key’ Representatives who serve on infrastructure related and appropriations committees. The meetings lasted 15 to 30 minutes each, and a leave behind packet was given to the Legislator or staff member containing an overview of current key issues.
Most discussions began with a brief overview of the results and conclusions of the 2017 Infrastructure Report Card, which assigned America an overall grade of a D+, unchanged from 2013 and indicating the continuing needs for infrastructure investment. The Report highlighted that while the benefits were seen in seven categories where investments were made, three categories continued to fall short, and the remaining categories were holding steady, resulting in a lower of grades. The focus of all discussions was the need for consistent and sufficient funding, and the requirement of bold leadership from all.
One of the key items discussed were the FY17 and FY18 Spending/Appropriations Bills so that the FAST Act’s increased funding can take effect during this fiscal year and next. Congress passed the five-year surface transportation act in December 2015 and included an increase in funding to help improve the nation’s highways, bridges and transit systems. Most of the legislators were on board with the appropriations, however there seemed to be a lack of commitment without knowing what the new Administration’s Budget would contain. If a Continuing Resolution (CR) is passed, then Pennsylvania will miss out on over $115 million dollars for FY17 alone due to the lack of a Fast ACT Appropriations Bill ($1.58 billion up to $1.69 billion).
Additionally, the team discussed several water issues with the Representatives and staffers that included the Clean Water State Revolving Fund (SRF) and the Drinking Water State Revolving Fund. We asked the Representatives and Senators to reauthorize the Clean Water and Drinking Water SRF’s which hasn’t been done since 1990 and 1994. With most of America’s drinking water and wastewater infrastructure in need of repair and many areas dependent on these funds, the team advocated for both SRF’s to be tripled in appropriation from $1.39 Billion to $4.17 Billion for the Clean Water SRF and $863 million to $2.58 billion for the Drinking Water SRF in accordance with President Trump’s commitment to triple the SRF’s.
In 2016 after years of work the Water Infrastructure Investment for the Nation (WIIN) Act passed through Congress and was signed by the President. WIIN supported previous pieces of legislation but Congress has yet to appropriate the promised funding in any of them. In 2014, Congress reauthorized the National Dam Safety Program (NDSP) in the Water Resources Reform and Development Act (WRRDA) and established new High Hazard Dam Rehabilitation Program to provide grants to high hazard non-federal dam rehab repair or renewal. The NDSP program is authorized at $13.9 million a year until 2019 and the federal rehab program is authorized at $445 million over 10 years though neither have received any funding. In addition to dams, the team discussed the Levee Safety Program. With the WRDDA Act of 2014, Congress established a new levee program to promote consistent safety standards, create levee guideline, and provide funding assistance to the state for establishing participating levee safety programs. The program is authorized for $395 million dollars over 5 years however it has not received any appropriations for funding.
Lastly, with the push for tax reform and the discussion that is forthcoming including all tax exemptions, ASCE took the opportunity to remind legislators that tax-exempt municipal bonds are often relied upon for municipalities to complete infrastructure projects. The team discussed the importance of maintaining their tax-exempt status as just one of many ways to trim our infrastructure deficit.
This year will be a busy one for the ASCE PA Government Relations team, with a State Infrastructure Day (Fly-In) scheduled for May 9th and efforts for the 2018 Report Card for Pennsylvania’s Infrastructure kicking off in the fall. If you are interested in participating in either of these events, please contact the Pittsburgh Section Government Relations Committee Chair, Greg Scott, at email@example.com.

More than 75 ASCE members and guests gathered at the Gaetano’s Banquet Restaurant on Thursday, February 23rd, 2017 for an ASCE Pittsburgh Section Geo-Institute Chapter meeting. Dr. Suresh K. Gutta, P.E. of American Geotechnical and Environmental Services, Inc. presented the lecture “New Baltimore Landslide Remediation – Design Perspective.” The presentation focused on monitoring an active landslide, remedial design methods, and construction observations.
In 1940 the Pennsylvania Turnpike was constructed mostly along the path of the original alignment of the old South Penn Railroad, and thus passed through the Borough of New Baltimore, PA, and the Allegheny Mountains. The original construction reactivated an ancient landslide, referred to as the ‘New Baltimore Slide’ that had occurred in the geologic past due to undercutting of the mountain slope by the Raystown Branch of the Juniata River, which lies in the valley just beyond the limits of the present Turnpike alignment. This reactivated slide zone extends to 800 feet along the roadway alignment and 1,500 feet upslope. An average of 60 feet of soil and bedrock overburden has been slowly sliding along a weathered clay-rich siltstone failure plane for over 70 years, resulting in a recorded movement of 13 feet and causing major cracks along the mountainside.
The current widening and the reconstruction of the Turnpike required the removal of the toe support of this active slide. Dr. Suresh Gutta talked about the how the design involved characterizing the failure mechanism, the challenges of installing geotechnical instrumentation in the rugged mountainous terrain, and the technologies used to record and report the data remotely. The talk also addressed the design treatments required to stabilize the slide mass, including the development of a specific sequence of construction, and safety systems necessary for the protection of traffic during construction. Construction of the remediation was completed in September 2016.
Attendees earned 1.0 PDH for the presentation.
The February meeting also brought out a number of the past Pittsburgh Geo-Institute Chairpersons. We seized the opportunity to capture a ‘geotechnical cross-section’ of these stewards of our professional society. Thank you all for your contributions in making our local Geo-Institute Chapter such a longstanding, successful program.

David Lattanzi, PhD, PE is an Assistant Professor at George Mason University, specializing in robotics, 3D visualization, and artificial intelligence as it relates to Civil and Structural Engineering. He presented at the annual Pittsburgh SEI Chapter and ABCD Organization joint meeting on these topics and how they are changing the industry.
One emerging technology is the use of Unmanned Aerial Vehicles (UAVs), commonly known as drones, to assist with the inspection, analysis, and review of structures during most phases of construction and maintenance. A camera or similar recording device can be connected to a drone to capture video of the entire structure from multiple angles as the UAV is flown around the structure. The recorded data is detailed enough to review individual images of small components such as bolted connections, as well as larger components such as steel or concrete girders. Additionally, the data can be processed to develop 3D point clouds of the entire structure. With this information, one can review overall dimensions, full-system interaction, and potential structural defects. The user also has the ability to zoom into select details of the structure and access the pictures taken from the drone at that specific location.
Dr. Lattanzi also shared some lessons learned while conducting a case study using UAVs to analyze a bridge or structure. First, planning is key. The team quickly determined that having a plan of the expected flight routes and the camera views/orientations was extremely important. To capture all the components of the structure and make a complete 3D model requires overlapping images from multiple angles and directions. Another lesson learned was that communication between team members is extremely important, both during the inspection and while manipulating the data to create the 3D model. Finally, the entire team agreed that one thing is certain: Inspectors aren’t being displaced anytime soon. For inspectors and engineers, drones are a new tool and the data they provide is the product. UAVs can capture data, but inspectors are required to understand the photo content and determine the importance and requirement for additional analysis or repair. This is similar to how engineers have come to embrace computers and technology for assistance in designing structures. Computers don’t design an entire structure; design requires input and judgement from an engineer to determine what is appropriate and how to analyze the output .
While it is encouraging that the industry embrace UAVs to streamline the construction and inspection processes there is still an uphill battle before full implementation can be achieved. First and foremost, there are a lot of regulations limiting where flights are allowed and how UAVs are used in the field and on construction sites. Additionally, measurements of defects can be estimated from images and data, but actual physical testing (such as hammer sounding, chloride tests, field measurements of cracks) can’t be accomplished. Furthermore, until operators have more experience and better understanding of the required process and approach to use while recording video and data, there is the potential that certain items may be missed that would have been found if inspectors physically reviewed all the connections and members in person.
The presentation served to bring awareness to the use of UAVs and the data they collect to structural engineers, inspectors, and contractors who may be considering using drones to streamline inspections and construction for upcoming projects. This is just an overview of some of the benefits and limitations of UAVs in the construction industry. It is important to contact trained professionals that are knowledgeable in the use of UAVs when determining the applicability for a project and the appropriate information required to make its use successful.
Stay up to date with the latest news in the P3 Rapid Bridge Replacement Project.
Pennsylvania had approximately 4,500 structurally deficient bridge as of 2012; to try to address a portion of these bridges PennDOT took advantage of a public-private partnership (P3) known as the Rapid Bridge Replacement Project (RBRP). RBRP is a project to replace 558 structurally deficient bridges across Pennsylvania in three years and then maintain the following 28 years. As the project continues and a very busy construction season for RBRP this upcoming summer, you can follow all the work on the RBRP blog here. Also on the site, you can search each county to see what bridges are near you and what the schedule is for them as well as current pictures of the structural deficient bridges and once completed of the new structures.
