Bill Simpson, P.E.Geotechnical Structure Design Specialist at Gradelta Engineering
Mr. 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: Internal Design of MSE Walls and Geosynthetics
Delivery Method: Live Online
Course Description: This three hour course will cover the design of and materials used in the construction of mechanically stabilized earth (MSE) retaining walls. It will examine geosynthetics, wall properties, code requirements, equations and calculations, and case histories of MSE failures that highlight what NOT to do.
Learning Objective 1:
Learners will be able identify and describe the materials that are used in the construction of a MSE wall, which include geosynthetics.
Learning Objective 2:
Learners will be able to compare geosynthetics that are used in MSE walls by cost, strength and applications.
Learning Objective 3:
Learners will be able to describe how MSE walls interact with other site features such as buildings and utilities, and they will be able to discuss the effects of water on the design and stability of the wall.
Learning Objective 4:
Learners will be able to work with calculations for internal stability of a MSE wall and be able to reference and understand code requirements for MSE walls.
