INSTRUCTOR:  Jerry A. DiMaggio, P.E., D.GE, M.ASCE

Purpose and Background

The United States earth retaining structure market exceeds millions of square feet annually and there are many different retaining systems to select from which are unique in design and construction. Unit costs vary from less than $30 to in excess of $300 per square foot. Selecting the most technically appropriate and cost-effective system is often critical to project cost, schedule and long-term performance. Selection of an inappropriate system unfortunately can result in time consuming and costly construction and contract disputes. Many engineers, contractors and project managers do not have the needed knowledge and skills to select, design, construct inspect these systems.

During this course the instructor provides critical knowledge and skills you need in order to take advantage of the technically appropriate and cost effective earth retaining structures for infrastructure projects. From start to finish - from design to construction and general site development - the instructor will lead you through the myriad of different retaining wall systems.

The instructor presents a logical sequence of topics to allow participants to develop their knowledge and skills. These activities include: lecture, interactivity, instructor lead example problems and lively discussion periods. All participants will receive a PDF copy of course PowerPoint visual aids.

Benefits and Learning Outcomes

Upon completion of this course, participants will have gained enormously from the experience and the practical knowledge of the instructor and will be able to:

• Recognize potential applications for earth retaining structures used in civil engineering applications
• Select the most technically appropriate and cost-effective earth retaining system for your application
• Examine and select appropriate material properties, soil/rock design parameters and earth pressure diagrams
• Prepare conceptual and basic designs using appropriate design methods, factors of safety, earth pressure diagrams and field verification methods
• Evaluate and review contractor submitted designs
• Select appropriate specification/contracting method(s) and prepare contract documents
• Demonstrate a clear understanding of retaining wall system construction and maintenance

Assessment of Learning Outcomes

Achievement of the learning outcomes will be assessed via a post course examination and review summaries following the presentation of each major topic.

Who Should Attend?

This program is developed to meet the needs of generalist civil engineers, geotechnical and structural specialists, contractors, and retaining wall company representatives.
