Standards · Engineered Precision (Part 4) vs. Prescriptive Paths (Part 9)

This post will focus on something fundamental to our everyday lives as structural engineers in Canada: the National Building Code of Canada (NBCC) and, more specifically, how we navigate the structural design requirements of Part 4 versus Part 9. Ever found yourself scratching your head over whether a project really needs the full Part 4 treatment, or if Part 9’s prescriptive paths are sufficient? You’re not alone.

In this post we’ll be looking at seismic. Specifically, let’s chew on something that’s been a hot topic since the NBCC 2020 dropped: the growing gap in seismic design philosophies between Part 4 (Structural Design) and Part 9 (Housing and Small Buildings). If you’re juggling projects that dance on the edge of Part 9’s limits or work across different seismic zones in Canada, this is a conversation you need to be in on.

Let’s talk about something that trips up even seasoned engineers from time to time: figuring out exactly where National Building Code of Canada (NBCC) Part 9, “Housing and Small Buildings,” hands off the baton to Part 4, “Structural Design.” Get this wrong, and you could be heading for a world of compliance headaches, or worse, an under-designed structure. Get it right, and you’re setting your project up for success from day one.
