Concrete contractors building deep pit barns should plan to attend a DNR training session on concrete design and construction. Six sessions begin next week and are offered throughout the state.

DNR permit engineers Paul Petitti and Cindy Garza will lead the sessions, focusing on the pre-permitting process and state requirements for constructing a deep pit hog barn. Producers, engineers, consultants and staff from geological technical firms are welcome.

Expect in-depth coverage on successful construction in alluvial soils (sands and gravels) and karst terrain, an overview of flood plain requirements and tips for constructing in challenging weather. Each two-hour session will feature lessons learned from 44 years of experience in animal feeding construction and engineering.

Also featured: How to use the AFO Siting Atlas to locate environmentally sensitive areas with special regulations, and the nitty-gritty of rebar spacing, water stop installation, concrete curing and perimeter tiles.
