Engineering Professional Development

Understanding Plumbing Systems in Commercial Buildings See upcoming dates

Course Overview

Plumbing is essential to the basic infrastructure of most buildings, but it’s not often taught in traditional degree programs. Also, specialized kitchen and laboratory requirements are increasingly costly and complex to install and maintain. By improving your understanding of the design, installation and operation of plumbing systems, including water piping, waste and vent, storm water, specialty gases, and equipment—you’ll be able to tackle these systems with ease.

Who Should Attend?

  • Mechanical system design engineers
  • Plumbing estimators and installers
  • Building code officials and inspectors
  • University and government facility operators
  • Commercial office building superintendents
  • Equipment sales and technical representatives
  • Construction managers and contractors
  • Architects and project team consultants


"It was a very interesting course that covered a broach spectrum of topics in a way that allowed everyone in the room to comment, which was outstanding and very productive to provide different points of view."
—Dave, Master Plumber, Marshfield Clinic Health System, Marshfield, Wisconsin
"I came in with only moderate plumbing knowledge picked up on one or two projects. I feel that I have a good store of general system knowledge that I can apply going forward."
—Clayton, TKDA, St. Paul, Minnesota
"It was good to focus on plumbing principles and hear experiences from others in the industry...I can use many aspects of this course daily in my job, especially for design-build projects."
—Brian, Assistant Project Manager, J.F. Ahern Co., Fond du Lac, Wisconsin
"I came in with the hope I would learn about all the different kinds of systems and their related equipment, and I now have a much better understanding of both."
—Brad, Sherman Mechanical, Cary, Illinois
"Learned all of the basics of plumbing systems, as promised...Very good course, glad I took it."
—Teddy, Mechanical Engineer, Kohler Co., Kohler, Wisconsin
"I liked how there was a lot of knowledgeable people within the class, and created some great dialogue...Learned a lot from instructors and classmates." —
—Greg, Plumbing Estimator, Butters-Fetting Co., Inc., Milwaukee, Wisconsin
