Course Catalogue.

After participating in this course, you will be able to:

• Recognize potential MSE wall applications for transportation facilities
• Understand the primary design considerations and select appropriate parameters for the design
• To be able to check contractor-submitted designs for MSE walls
• Select appropriate specification and contracting methods
• Identify appropriate construction inspection activities to confirm compliance with the design

Description
The design, construction and long-term stability monitoring of MSE walls continues to evolve as designers, researchers, and specifiers push the leading edge of the technology and use more advanced geosynthetic materials and systems. MSE walls represent more than half of all retaining walls used for transportation applications. MSE walls offer some fairly significant advantages for constructing transportation infrastructure. They are used to reduce or eliminate the need to improve poor foundations where piles, caissons or other soil stabilization techniques would be required for conventional reinforced concrete retaining walls. They are most commonly used as cost-effective solutions where the cost of fill, right-of-way or other restrictions require a steeper slope than is practically possible. 

Many types of MSE wall types are categorized by the geometry of the reinforcement, the mechanism used to transfer stress, the type of reinforcement material (metallic or non-metallic) and the type aand geometry of the wall facing. This webinar provides a basic understanding of the type of MSE walls, their primary uses, key factors in their design and lessons learned from construction. A series of case studies provide the “good” the “bad” and the “ugly” experiences with the use of MSE walls, along with key lessons learned for their long-term success.

Who Should Attend

• Engineers involved in MSE wall design, construction and maintenance
• Provincial/State DOT and municipal agency personnel who specify MSE walls
• Specifiers and manufacturers of earth-retaining structures
• Contractors interested in advancing the state of MSE construction technology
