Helical Design: Code Compliance and Effects of Seismic Activity (Archived Webcast)

Originally Aired March 1, 2017. This webcast has expired

Helical piles and anchors have been used in construction applications for more than 175 years. The first recorded use of helical piles was in 1836 by Alexander Mitchell in England. The helical pile industry has seen substantial growth in the last 20 years as most practicing engineers have recognized the strength, versatility, and many applications of the system.
The popularity of helical piles has grown so much, the International Code Council (ICC) established acceptance criteria AC358 for helical piles in 2007. ICC inducted helical piles into the International Building Code in 2009. However, helical piles were barely mentioned in undergraduate and graduate civil engineering studies.
The presentation will cover the design, applications, and building code requirements of helical piles.

Recommendations for Bioretention Media Qualification (Print PDH from the November/December 2016 issue of Informed Infrastructure)

This PDH has expired

Engineered bioretention media is optimized to filter and/or infiltrate stormwater runoff through a plant-soil-microbe complex. A successful bioretention installation involves oversight—not just onsite, but having a framework in place for transferring raw materials to a blended, commercially installed product. Read this “instruction manual” on how to successfully implement a bioretention media strategy. Then take the accompanying quiz to receive continuing education credit.

As seen in the November/December 2016 issue of Informed Infrastructure magazine.
