Knowledge for Better Design of Geosynthetic Reinforced MSE Structures
Instructor, Michael Simac, P.E., EARTH Improvement Technologies
This course is intended for geotechnical, civil, and structural engineers who wish to expand their abilities to plan, analyze, design and investigate geosynthetic reinforced Mechanically‐Stabilized Earth (MSE) structures. Previous MSE design experience is helpful but not required. After a brief introduction of MSE design guidelines and procedures, this session will focus on the most common problems associated with poor MSE structure performance, and how to address those issues from an engineering design perspective. This knowledge of past experiences will allow designers to focus their analytical, investigative, observational, and geotechnical data interpretation techniques to improve performance on future MSE designs, through more focused design procedures, better construction drawings and details, specifications, internal drainage design, and quality assurance testing for special inspection requirements. The MSE designer’s interaction with the project team; Owner, Contractor, Architect, Site/Civil and Geotechnical Engineers, will be discussed as to its effects on site planning, utility location and performance, and overlapping design / professional responsibilities.
Designing with Geosynthetics – Construction Protocols
Instructor, L. David Suits, LDS Geosynthetic Consulting Services
Examine geosynthetics in roadway applications such as drainage, erosion control, pavement overlay, embankments, and Reinforced Soil Slopes (RSS) while developing an appreciation for proper protocols, clear specifications and sustainable construction. Individuals involved in constructing with geosynthetics including construction contractors and geotechnical, civil, and environmental engineers will find this review of the types, applications and guidelines for use geosynthetics in roadways a solid foundation for understanding road construction protocols.
