Design, Construction, and Inspection for Mechanically Stabilized Earth Walls

Ce webinaire a été offert en anglais.

This webinar provided an overview of best practices for the selection, design, construction, and inspection of mechanically stabilized earth (MSE) walls with a focus on public works projects. It also highlighted key features of the division of responsibilities and design considerations to compliment and preserve those divisions.

MSE walls are a mature earth retention technology. With a growing number of these structures in Canada over the past few decades, concerns may arise over ultimate responsibility for wall design, quality assurance, asset management and repairs, and post-construction in-service monitoring, particularly for significant construction or performance issues.

The webinar is based on contents from TAC's Design, Construction, Maintenance and Inspection Guide for Mechanically Stabilized Earth Walls.

• Questions and answers

Learning Objectives

• Understand MSE wall components and typical applications     
• Understand considerations for selecting soil reinforcement
• Identify participating stakeholder roles and divisions of responsibility for select roles
• Identify three common applications for public works projects
• Understand, conceptually, how site conditions, application, design choices, construction and other considerations can affect performance

Target Audience

Stakeholders involved in MSE walls delivery or projects that include MSE walls:

• Public infrastructure owners
• Coordinating professionals
