This 1-hour PDH is presented by Brian Groff of Duchland, Inc. Concrete is the foundation of our water and wastewater infrastructure. While concrete structures come in many types, sizes, and shapes, not all concrete construction is equal. Utilizing precast, post-tensioned concrete structures allows for limitless custom designs and higher concrete strength and quality. In addition, installation can be accomplished in days or weeks rather than months, utilizing reduced site constraints as well. This presentation will evaluate the differences between precast, post tension concrete and cast in place, including material variables. This presentation will also review multiple case studies for both water and wastewater applications.
