This talk will provide an introduction to the design and structural interaction of Geopier Rammed Aggregate Pier (RAP) & Rigid Inclusion systems with shallow spread footing and slab on grades.
These systems are ground improvement technologies that can be used to increase bearing capacity and control settlement of buildings, tanks, retaining walls, and embankments to close tolerances. Depending on site requirements, Geopier systems can be installed using replacement or displacement methods. RAP systems are used to reinforce good to poor soils, including soft to stiff clay and silt; loose to dense sand; organic silt and peat; variable, uncontrolled fill; and soils below the ground water table. They can be used as an alternative to deep foundations or over-excavation, and provide cost and time savings on sites where building on existing poor soils and/or undocumented fill present unacceptable risk to the owner.
This presentation reviews fundamental Geopier design and construction techniques and discuss the collaborative effort between the project structural engineer and RAP designer needed for a successful project.

Future World Vision
Civil engineers, in reimagining the world, must adapt how we design, build, operate, and maintain our infrastructure systems.
Using data-driven, in-depth, scenario-planning analysis, Future World Vision puts civil engineers in position to lead not just today but five decades into the future. Four types of cities are being imagined:
- Resilient Cities
- Progressive Megacities
- Dispersed Settlements
- Unequal Enclaves
By mapping out key trends and potential outcomes, a projected range of plausible future-based scenarios is being developed. Each scenario models how society might interface with cities, infrastructure, and operational systems, while illustrating what civil engineers must do to develop solutions for this changing future.
Future World Vision will help ensure that the decisions we make as civil engineers, in building high-tech, resilient, and sustainable communities of the future, optimize desirable outcomes while avoiding undesirable and unintended consequences.

Region 2 Member Shout Out
Nicholas Johnson and Philip Hater of the Reading Branch
Nicholas Johnson works at Great Valley Consultants in Reading, Pennsylvania. GVC is a small consulting firm focused on civil and municipal engineering in Berks County and surrounding areas. Nick focuses on Environmental and Water Resources engineering within the Civil Engineering discipline. He has gained valuable field experience in his 12+ year career which broadened his knowledge of other civil engineering specialties. He attended Penn State from 2003 to 2007 and joined ASCE in 2009. Nick joined because he wanted to branch out, and to better understand the experiences of other in our broad civil engineering industry, and to better serve in the civil engineering profession.
Philip Harter is currently juggling overtime, a toddler, and has a second child expected in May. As a structural engineer at Worley, Phil has had the opportunity to complete designs of numerous power generating facilities in the U.S. and around the world. Most recently, Phil has been lucky enough to be working on one of the first, major offshore wind power facilities in the United States. Phil joined ASCE during college as part of the Steel Bridge team and participated in the national event at the University of Florida. Phil stayed with ASCE after graduating from Penn State because it supported infrastructure investment and the education of the next generation of engineers.
Coincidently, it is interesting to note that Phil and Nick have been friends since 2000, when they met in the 9th grade at Governor Mifflin Senior High School in Shillington, Pennsylvania.
Please share in my thanks to both Nick and Phil for their involvement in ASCE and to their being part of the resurgence of the Reading Branch.
Visit an ASCE Designated Historic Site
These sites illustrate the creativity and innovative spirit of civil engineers. Visit https://www.asce.org/landmarks to find sites near you. Share photos of your travels with me and I will post in Region 2 correspondence and on our Region’s social media pages.
Detroit-Windsor Tunnel, Detroit MI, National Historic Civil Engineering Landmark
In November, I visited the historic Philadelphia City Hall. This month, I visited the Detroit–Windsor Tunnel which connects Detroit, MI to Ontario, Canada and was completed in 1930. It was the third underwater vehicular tunnel constructed in the United States. It was designed by the firm Parsons, Klapp, Brinckerhoff and Douglas. The tunnel is 5,160 feet in length and at its lowest point, the two-lane roadway is 75 feet below the surface of the Detroit River.
I look forward to seeing you at ASCE events:
- MRLC in Philadelphia, PA, Jan. 31-Feb. 1, 2020
- National Engineer’s Week, Feb. 16-22, 2020
- ASCE National Convention in Anaheim, CA, Oct. 28-31, 2020
- And your Section and Branch meetings
Enhanced membership. https://www.asce.org/member-benefits/
