In today’s world, cookie-cutter specifications are quite simple to piece together. Using any computer, a person can either modify an existing document that already has similar project specification, cut and paste specifications from an existing document into a current document, or cut and paste specifications from the internet. However, there are significant implications of cookie-cutter specifications, including the fact that they may be outdated, the person writing the specifications may have no idea what they actually mean, the specifications may actually lead to a lower-quality project, or the specifications may lead to constructibility issues in the field. This panel discussion will include participants from each of the vendor segments typically found on a geosynthetics installation: the design engineer, manufacturer, installer, and construction quality assurance (CQA). Each of the members of this panel will have an opportunity to provide insight into areas in which current specifications are either too limiting or too broad to allow quality installations to be performed and ways in which those specifications financially impacts these projects.

The design and construction of embankments on very soft foundations is one of most challenging geotechnical problems. Without some type of foundation soil improvement, failures are common–especially on very soft sites. Of the nine or ten possible soil improvement methods, soil reinforcement, especially with geosynthetics, is often the most feasible and economical; and, in face, some projects cannot be constructed without using geosynthetics. The course begins with a brief overview of conventional solutions to the problem, including historical treatments that lead to the purpose, applications, and functions of geosynthetic reinforcement. Case histories of early applications provide lessons for designers. Design concepts and detailed procedures for analysis and design are presented. The properties required for design, both with soils and geosynthetics, are described. Because proper construction procedures are so crucial for successful projects, a detailed discussion of these procedures completes the course.
Lecture outcomes include:
- Understand the place for geosynthetic reinforcement among all the available foundation soil improvement methods
- Principles and procedures for analysis and design of geosynthetic-reinforced embankments
- Material properties (soils and geosynthetics) required for design
- A detailed knowledge of the special procedures required for construction
The lecture will enable participants to:
- Identify soft ground projects where geosynthetic reinforcement will be feasible
- Understand the requirements for design, including material properties
- Appreciate the critical importance of proper construction procedures
Who should attend?
- Geotechnical and construction engineers and engineering geologists
- Consulting engineers, manufacture technical representatives, and academics specializing in geosynthetics engineering
- Earthwork and other specialty contractors involved in soft ground construction
