Good energy at Geosynthetics Conference 2019

The Geosynthetics Conference 2019 was a huge success in Houston, Texas, Feb. 10–13, with more than 1,100 engaged attendees, presenters, speakers and exhibitors contributing to the intellectual and commercial hum felt throughout the Marriott Marquis.

“We were delighted with the enthusiasm of the attendees and exhibitors,” said Industrial Fabrics Association International president and CEO Steve Schiffman. “From the technical sessions to the opening reception through the end of the conference there was a lot of learning, activity and engagement.”

“It was good energy here in Houston,” said Richard Thiel, P.E., of Thiel Engineering, the Geosynthetics Conference 2019 chair. “Our goal has been to provide a forum for face-to-face interactions that you can only get with conferences like this. You meet people, you talk with them, you collaborate and there’s such a variety of venues to make this happen, with all the plenary sessions, the technical sessions, the roundtables, the open panels, the tradeshow floor, the IAGI GeoGames, the hallway discussions. We’ve done it once again, and we’re going to continue doing it in the future.”

The conference provided a forum for multiple focus group and general membership meetings of the Geosynthetic Materials Association (GMA) and other groups.

“The Geosynthetics Conference 2019 provided a great forum for members of GMA to conduct business in person and learn about advancements in geosynthetic technologies through its stellar technical program,” said Jonathan Curry, managing director of GMA. “I was proud to be a member of the organizing committee, and I believe the conference format helps GMA achieve its mission of advancing the industry.”

A topic widely discussed at the conference is the importance of teaching geosynthetics in civil engineering education, as most civil engineers are not introduced to geosynthetics in their course of study.

Richard Brachman, P.Eng., of Queen’s University, spoke passionately about this lack of geosynthetics education, “What can you do to help? Talk to your alma maters, talk with former professors, and, if you can, talk to deans, and tell them we need to teach geosynthetics in civil engineering education. They are ubiquitous in every civil engineering project; we need it in undergraduate education.”

Mike Adams of the Federal Highway Administration, during the Roundtable/Open Discussion “Incorporating Geosynthetics in Civil Engineering Education,” noted, “It is highly beneficial to expose adolescents to geosynthetics because their natural creativity may be highly generative.”

Geosynthetics Conference 2019 was supported by IGS-NA and under the auspices of IGS.

XXIX Italian National Conference on Geosynthetics (Bologna, 18 October 2018)

The XXIX Italian National Conference on Geosynthetics was held on 18th October 2018 in Bologna, giving excellent results in terms of both number of registered attendees and quality of presented papers.

This time the conference theme was addressed to the presentation of the “A.G.I. recommendations for the use of geosynthetics in soil reinforcement: design of walls and steep slopes”.

The conference was organised by the Italian Geotechnical Association (AGI) and by the Italian Chapter of the International Geosynthetics Society (AGI-IGS), in partnership with BolognaFiere, under the auspices of the National Engineers Council (CNI), the Association of Bologna’s Engineers and the University of Bologna.

The conference took place in the context of the SAIE Exhibition (the international reference point for the world of construction in Italy) and it was divided in two different sessions.

The morning session was coordinated by Daniele Cazzuffi (AGI-IGS President) and, through a series of invited lectures, it concerned the basics regarding the geosynthetic-reinforced soil structures, the characterisation of the design parameters and the methodologies of analysis both in static and seismic fields. The first lecture was presented by Nicola Moraci (Mediterranea University of Reggio Calabria, Italy) and it focused on the “Basics and working principles of the design with geosynthetic”, taking into account the practices currently used worldwide and the recent developments achieved with regard to construction technologies.  The second lecture was presented by Giuseppe Cardile (Mediterranea University of Reggio Calabria, Italy) and it focused on the “Materials used for earth reinforced wall construction: characterization for a correct design”, in which all the requirements for the evaluation of the design parameters were debated. The third lecture presented by Marilene Pisano (Mediterranea University of Reggio Calabria, Italy) was entitled “Italian design code and current international standards and recommendations”. The last lecture of the morning session was presented by Giovanni Biondi (University of Messina) and Paolo Carrubba (University of Padua) on the “Static and seismic analysis methods“.

The afternoon session started with the presentation of the AGI-IGS Award for the best thesis on Geosynthetics Engineering discussed in the last two years in an Italian University. The winner was Stefano Anzani (Politecnico Milano) with a Master’s Degree thesis on the “Study and development of an innovative adhesive anchored external waterstop for the waterproofing of joints in concrete face rockfill dams”.

Nicola Moraci (AGI President) coordinated the afternoon session, in which invited lectures illustrated the numerical design approaches and examine comprehensively the practical aspects such as realisation, testing and monitoring, passing through a design example that will show the correct application of the new national technical code (NTC2018). Specifically, Claudio di Prisco (Politecnico Milano) presented a lecture on the “Numerical design approaches”, Piergiorgio Recalcati (Tenax SpA) and Pietro Rimoldi (Officine Maccaferri SpA) presented a “NTC2018 design practical case and the differences with the previous code”, while Maurizio Schiavo (Sogen srl) gave a lecture on “Realization, testing and monitoring of earth-reinforced structures”.

At the end of each session, a fruitful and interesting discussion on the different topics took place.

The next XXX Italian National Conference on Geosynthetics will be held in 2020.

IGS Young Members: Down to Earth – An Interview with IGS President, Professor Chungsik Yoo, PhD

11 ICG Seoul Geosynthetics

Chungsik YooIn this edition of the regular feature, the young members committee interviewed the recently elected president of the IGS.

Name / Institution: Dr. Chungsik Yoo, PhD., Sungkyunkwan University, South Korea.

Specialist Field: Geotechnical Engineering, Geosynthetics, Geosynthetics reinforced walls and slopes, Tunnelling, Large-scale numerical modelling of geo-structures.

What originally inspired you to enter civil engineering, and what continues to do so?

During the mid-1970’s, when I was in high school, South Korea’s economy was booming and there was a significant expansion of urban populations. Significant infrastructures such as metros, railways, roadways, urban infrastructures, etc., were needed, and therefore South Korea was literally under construction. At that time, I was fascinated by the fact that a city, especially Seoul, could be reshaped with construction activities and therefore decided to enter into civil engineering. During my college years, I became very interested in geotechnical engineering, especially geosynthetics and tunnelling, which in turn led me to pursue a PhD study. Whenever I revisit geotechnical principles and find solutions to difficult geotechnical projects with the geotechnical principles, I am still excited.

What do you enjoy most about working in the industry?

As a university professor, I often get involved in consulting work for the construction industry with my graduate students. I am very excited and happy when students learn how to solve real life problems with what they learned during the class and research work while they carry out a consulting project. This is indeed a win-win situation for all the parties involved, including myself, students, and industry.

When and where was your first involvement with geosynthetics?

During my PhD study at Penn State University in USA, I had to validate a three-dimensional finite element code that I developed. My advisor, Dr. Mian Wang, who happened to be a friend of Dr. B.M. Das, told me to contact him to get experimental test results on geogrid reinforced foundation. Dr. Das kindly provided me the results and I was fascinated by the fact that a polymeric material can improve the bearing capacity of a footing when properly installed. Since then, I have been deeply involved in geosynthetics.

Do you have any advice for young engineers beginning their careers? What do you think are the most important skills in today’s industry?

Today’s university engineering education is shifting its paradigm to educate students with multidisciplinary background. This is because society and industry need engineers with diverse skills and creative thinking. That said, I advise young engineers to try to bring a great deal diversity into the way they think. Fundamentals are also important in engineering. In order to become a competent geotechnical/ geosynthetic engineer, he or she must be good with fundamental geotechnical/geosynthetic principles. Last but not least, networking is also as important as technical side. Try to be actively connected with people.

What do you hope to achieve during your presidency of the IGS? How can young members contribute?

As the new IGS President, it is my responsibility to take full advantage of the wealth of achievements and to lead this great society to the next level. Just because the IGS is doing well doesn’t mean that we cannot do even better. It is critical for the IGS to remain forward-thinking and innovative. My aim is, therefore, is to focus on the future in order to move forward, while continuing to carry on the current agenda that have been planned. One of the important agenda during my presidency is “Get young members involved”. Young members are the future of the IGS. One of my top priorities will be expanding young membership to incorporate young minds for leadership development in the IGS. More opportunities will be given to young members to share knowledge and ideas, to connect with leaders in the field, and to have better education and training. I look forward to active involvement of young members in the IGS activities in the coming years.

Do you have any hobbies and interests outside work?

I enjoy Jogging, playing golf, listening to music and playing guitar (see below).
