Specifying modern timber connections

Innovation almost always moves faster than building codes can react. Codes, however, give provisions for the use of emerging new systems and manufacturers do their due diligence in research and development.

All system types listed in this article, and more coming, are readily available in North America; in most cases, they are actually imported to the continent, but more specifically distributed from Canada. All these distributers offer technical support from within the country, and most also offer engineering support with knowledge of the prevailing codes. The respective technical support can be enlisted in helping with engineering design, ideas, and offer proper installation and application guidance and instructions.

1 Numerous Construction Canada articles have focused on these innovative wood projects. Examples include “Why Wood Works: Designing the Richmond Olympic Oval,” by Jim Taggart (November 2009), “Building the Earth Sciences Building at the University of British Columbia,” by Eric Karsh (August 2013), and “Overcoming the Learning Curve: Design and Construction of the UBCO Fitness and Wellness Centre,” by Patrice R. Tardif (October 2013). (back to top)
