Before undertaking any on-demand effort, you should review the rules of your licensing/certifying entity. It’s your responsibility to determine whether or not this on-demand course meets your continuing education requirements.
You must take and pass a quiz in order to receive credit. You can take the quiz as many times as needed and there is no time limit on the quiz. Once the quiz is completed, you will be asked to download your certificate.
Videos that qualify for AIA, LACES, ASLA, or CLARB credit will require an extra week for processing.
Streamable MP4/PDF
Available approximately 1 week after the date of the live event or the date of your order, whichever is later.
To track your purchase you will need to create an account on the website using the email address used for your registration.
For most customers, the videos run like most streaming videos on the web. For videos that qualify for AIA credit there will be occasional question prompts that will not allow the video to progress unless they are answered and you will not be able to skip forward while watching the video.

Speakers
Bill Simpson, P.E.
Geotechnical Structure Design Specialist at Gradelta EngineeringMr. Simpson founded Gradelta Engineering in 2020 with the intent to help clients better understand the combination of geotechnical and structural engineering that he has worked with for the past 20 years. He earned his B.S.C.E. and M.S.C.E. degrees from Georgia Institute of Technology. He currently provides engineering services to contractors and fellow engineers for earth structure pricing, along with the plans and calculations needed for construction. He frequently consults with clients regarding the optimal structure type and location on the construction site to minimize risk and maximize useable space. He also works in the education sector providing not just seminars such as this one, but also acting as a subject matter expert creating study guide and test prep content for the NCEES Professional Civil Engineer exam. Mr. Simpson has also worked with lawyers and insurance companies during forensic investigation and lawsuits surrounding retaining walls and slope failures. His hope is that through the instructional services that he currently provides, slopes will remain stable and retaining wall failure will be eliminated.

Course Title: Retaining Wall Design and Slope Stabilization Techniques
Delivery Method: Live Online
Course Description: This course examines the forces that act on retaining walls and how they withstand those pressures/loads. The course examines how geosynthetics perform in retaining walls and slope stabilization efforts. Slope stabilization techniques are explained, as are retaining wall and slope failures.
Learning Objectives:
Learning Objective 1:
Learners will be able to identify and quantify the pressures and loads that act on retaining walls and how the walls are able to withstand those forces.
Learning Objective 2:
Learners will be able to identify how geosynthetics that are designed for retaining walls and slope stabilization are classified by type, method of manufacture, relative strength, relative permeability, and relative cost.
Learning Objective 3:
Learners will be able to describe deep-seated slope failures and causes, and learners will be able to identify appropriate slope stabilization techniques.
Learning Objective 4:
Learners will be able to explain how to prevent retaining wall failures through site layout and proper design strategies, and they will be able to recognize and respond to potential slope failures in the field.
LUs: 6.5 LU Type: LU|HSWs.
Prerequisites: Experience with site design and earthwork
Advance Preparation: None
Program Level: Intermediate
Course Expiration Date: 03/19/2024
