While mass timber projects are often motivated by their carbon benefits or exposed wood aesthetic, a deeper understanding of the cost drivers is key to their viability for most design teams. For example, the cost of connections can significantly affect the overall project cost. However, because mass timber connection design must consider structural objectives as well as aesthetics, fire rating requirements, constructability, shrinkage and swelling, and moisture protection, finding an effective and efficient solution may be challenging. To aid designers in this effort, WoodWorks has published a Mass Timber Connections Index with options for many common conditions. Created by structural engineers, architects and general contractors experienced with mass timber design and construction, it highlights lessons learned and presents carefully analyzed solutions to common situations. In this webinar, we will review the index in the context of cost, fire resistance, structural capacity, and constructability objectives, to help designers choose and detail the most appropriate connections for their projects.
