Continuing Education Credit Information
This webinar is open to the public and offers 7.5 PDHs to professional engineers, and 7.5 HSW continuing education hours to architects and landscape architects licensed in Montana. Courses and providers are not subject to preapproval in Montana.

Engineers, architects and landscape architects seeking continuing education credit in other states will be able to claim the hours earned at this webinar, in most cases. Refer to specific state rules to determine eligibility. No credit is offered to landscape architects in New Jersey.

The American Institute of Architects Continuing Education System has approved this course for 7.5 LU|HSW (Sponsor No. J885).  Only full participation is reportable to the AIA CES.

The Landscape Architecture Continuing Education System has approved this course for 7.5 HSW PDHs.  Only full participation is reportable to the LA CES.

The International Code Council has approved this event for .75 CEUs in the specialty area of Sitework (Preferred Provider No. 1232).

Speakers

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.
