This hybrid online class will combine both live instruction and independent online work that you will complete during the day. Independent work will include quizzes, readings, videos and short assignments. Access to a computer with a webcam (either a camera that is built into your laptop or one that connects via USB), a reliable internet connection and a workspace that is free from distraction and noise will set you up for success.
A rapidly growing segment of pipe projects include trenchless technology. Jacking projects are less disruptive to the traveling public, communities, utilities and businesses. Trenchless installations save time, money, and improve roadway safety. Understanding this construction process can provide valuable insight into the trenchless process, and how it can be used not only for new construction but also as a replacement of failing culverts. Trenchless culvert replacement incorporates the concept of jacking pipe under existing roadways and consuming the existing pipe while increasing hydraulic capacity. As our nation’s infrastructure approaches the end of its service life, jacking procedures are a valuable option worth considering.

Who Should Attend
This class was developed as an introduction to trenchless pipe & culvert installation. We will cover many of the keys to a successful trenchless project. The content is intended for installers and design engineers but will begin from an entry level that will allow curious new comers to explore the world of underground construction.
