Slope Stability and Geosynthetics
Webinars are conducted on a platform called Go-to-Webinar. Instructions and
login information will be provided in an access email sent closer to the date of the webinar.
View system requirements here.
All attendees must log-on through their own email – attendees may not watch
together if they wish to obtain CE credit. HalfMoon Education Inc. must be able to prove
attendance if either the attendee or HalfMoon Education Inc. is audited.

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.
