Dr. Majid Talebi, P.E. will be presenting “Advantages of Reinforced Earth over Other Retainage Systems” at the 47th Annual Midwest Geotechnical Conference on Tuesday, September 25, from 1:45-2:30 pm.
This event is sponsored by the Illinois Department of Transportation.

Dr. Gennaro G. Marino, P.E., D.GE will be presenting “Encountering Geo-Construction Difficulties” at the October 2018 Meeting of the Central Missouri Chapter of CSI. His presentation will be on Friday, October 5th, at 12:00 pm.
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 $15 to attend. Please email eshay@meacorporation.com by October 1 to RSVP. Checks can be made out to CSI Central Missouri Chapter.
This event is sponsored by the Construction Specifications Institute Central Missouri Chapter.
Dr. Gennaro G. Marino, P.E., D.GE will be presenting “Mine Subsidence Engineering: An Overview” at the 2018 SEAOI Central Chapter Trade Show and Symposium. His presentation will be on Thursday, September 20th, from 3:45 – 4:40pm.
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, how mine stability relates to the resulting ground movements, and how 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.
This event is sponsored by the Structural Engineers Association of Illinois.

Dr. Gennaro Marino, P.E., D.GE will be presenting “Response of Petro Pipelines to Mine Subsidence” at the 35th Annual Meeting of the American Society of Mining & Reclamation on June 4th, 2018. His presentation will be from 3:00 – 3:30pm.
Presentation Abstract:
When transmission pipelines are planned to be undermined by longwall mining, there is considerable concern for the integrity of the pipeline. With longwall mining, there is typically significant associated subsidence movement. As a result, oil/gas transmission lines are exposed to subsidence induced axial tensile or compressive stresses and bending stresses as well as stress concentrations in associated appurtenances. With the use of case histories, this presentation will discuss the nature of longwall ground movements, the role the backfill properties play in the induced stress, and means to monitor and mitigate those stresses. The presentation will also include important aspects of analysis when evaluating subsidence effects.
Dr. Gennaro G. Marino, P.E., D.GE will be presenting “Geoforensics for Engineers” at the 2018 Indiana Society of Professional Engineers Conference on June 8, 2018. His presentation will be from 3:40-4:20 pm. This presentation will provide an overview of what constitutes a geoforensics investigation. In addition to providing a basic to detailed definition of geoforensics, the presentation will summarize 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. In performing geoforensic investigations, the standard of what “a reasonable degree of engineering certainty” means will be discussed. The presentation will conclude with a discussion of lessons learned based on Dr. Marino’s experience.
