Description

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.

Modules will be released on Mondays on a weekly basis beginning with a 30-minute live zoom session from 4:30pm to 5:00pm.  Independent online work will include a recorded lecture, quiz, and homework assignment. You will have 7 days to review the lecture and complete the weekly assignments. The instructor will be available by email and phone for questions and comments during the class and will be interacting with students as needed. The 4-week class will take approximately 6-8 hours to complete over the 4-week period.

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.
