Dr. Gennaro G. Marino, P.E., D.GE will be presenting “Encountering Geo-Construction Difficulties” at the March 2019 Meeting of the Cincinnati Chapter of CSI. His presentation will be on Wednesday, March 13th, at 11:50am.
This presentation will provide an overview of what constitutes a geoforensics investigation of a geo-construction problem. In addition to providing basic to detailed definitions of geoforensics, the presentation will summarize all the key components of a forensic investigation, and the varied causation components to the failure or problem. Each component will be discussed in detail with salient examples of actual case histories the presenter has investigated. MEA has been involved in cases which involved claims of up to about $1 billion dollars. Also discussed will be how a contractor should proceed once a potential geo-construction problem is identified, including do’s and dont’s of how to approach geoforensics investigations. The presentation will conclude with a summary of key points when encountering geo-construction difficulties.
The event costs $25 to attend for non-members. Please register on CSI Cincinnati’s website here. This event is sponsored by the Construction Specifications Institute Cincinnati Chapter.

Dr. Gennaro G. Marino, P.E., D.GE will be presenting “Mine Subsidence Engineering: An Overview” at the January 2019 Meeting of the Illinois Society of Professional Engineers Capital Chapter on January 29, 2019 in Springfield, IL.This presentation covers key aspects of mine subsidence engineering, a subject that is not well understood, and embraces a number of engineering disciplines. It focuses on the cause of mine subsidence and how mine stability relates to the resulting ground movements. Different mining and geologic conditions determine the mode of failure of the mine. The mode of mine failure in turn affects the resulting subsidence movement. Prediction of subsidence and damage potential are also key aspects of subsidence engineering. Examples of expected subsidence damage as well as mine stabilization will be shown.This presentation will be presented in a manner that will be understandable to anyone that would be interested in learning more about mine subsidence.

Dr. Gennaro G. Marino, P.E., D.GE will be presenting at a Metropolitan Bar Association of St. Louis CLE event on Friday, December 14, 2018 in St. Louis, MO. The objective of this presentation is to provide attendees an understanding of all the components of expert geoforensic investigations from an expert’s perspective. With such an understanding, attorneys involved in cases with ground or subsurface related issues will have better control and efficiency in processing such cases. The presentation will include review of the various elements of how a geotechnical failure can occur and how to proceed in investigating and prosecuting such cases. Key case examples which the author was intimately involved in will be introduced to illustrate and provide clarity to important concepts. Although the focus of this presentation is geotechnical engineering in nature, many of the concepts or principles disseminated would be applicable to prosecuting other expert engineering or forensic cases. Also, at the end of the presentation, some advices are provided from an expert’s perspective.
Registration begins at 8:00 am, and the presentation will run from 8:30 – 10:30 am. The presentation is approved for 2.4 MCLE Credits.
Introduction to Numerical Modeling in Geotechnical Engineering with Emphasis on FLAC Modeling
January 21-23, 2021 • Zoom Online Meeting • Instructor: Dr. Siavash Zamiran, P.E.
MEA, Inc. of St. Louis, MO is hosting a 3-day workshop on Numerical Modeling in Geotechnical Engineering. The workshop will be on January 21 to 23, 2020 and will be taught by Dr. Siavash Zamiran, P.E.
This course is an introduction to modeling geotechnical problems using commercially available geotechnical programs with an emphasis on FLAC.

Testimonials
“Anyone with solid background knowledge, looking for practical experience in continuum and discontinuum geomechanical modelling, will find the course a very robust and hands-on introduction to three of Itasca’s well-known numerical simulators. Working for a state mining regulator, I had so far relied on theoretical knowledge and common sense when it came to assessing study results obtained with the help of one of the programs. Thanks to Dr. Zamiran’s thorough lectures, the opportunity to ask questions and the chance to experiment with basic models of my own, I now have a much better understanding of the practical workflows, options and pit-falls in such undertakings. The course will be particularly useful to anyone planning to professionally use one of the programs in the near future.”
“I am a reservoir engineer dealing with the technical operational aspects of underground gas storage. It was really helpful to learn about the usage of the widely used numerical software packages in the industry and how they can handle praxis-oriented geomechanical problems on a theoretical basis. During the course, I learned how to investigate in the future my technical questions on my own with the help of technical descriptions of applied programs. Many thanks to Dr. Zamiran, with his help now I am ready to continue my technical education in the field of geomechanical modeling by the application of industry-leading numerical simulators.”
