Participants will learn about changes in the NDS and Supplement relative to previous editions and gain an overview of the standard. This article will highlight changes in the NDS and NDS Supplement relative to previous editions and provide an overview of the standard.
Significant changes relate to incorporation of cross laminated timber, open front diaphragms and cantilever diaphragms. This article provides an overview of changes for the Permanent Wood Foundation PWF Design Specification —a publication intended to address structural design requirements of a wood foundation for light-frame construction.
