Course Overview
Bond Tower is a 7-storey mixed-use prototype that asks a critical question: how can mass timber be made cost-effective in the Prairies, where supply chains are limited, demand is low, and timber construction is often reserved for flagship projects. Funded by the Green Construction through Wood Program from Natural Resources Canada, the project develops both prototypes and a built demonstration to advance affordable timber solutions in a region underserved by the current market.
The design leverages nail-laminated timber (NLT) as its primary system, applied in diagrid trusses, floor assemblies, and shear walls. NLT presents a cost-effective alternative to other manufactured products and provides great versatility due to its custom nature. Lateral and gravity-induced forces are carried by a diagrid timber truss fabricated from readily available dimensional lumber and using simple mechanical fasteners. Floor assemblies comprised of NLT are constructed without a concrete topping or proprietary sound attenuation systems, reducing both cost and embodied carbon. Prefabricated wall panels, stairs, and modular service pods further minimize waste and construction time.
Another challenge lies in building code classification. Currently, all structures above six storeys are deemed high-rise, requiring costly and difficult to achieve [in timber] two-hour fire-resistance ratings and fire-safety systems. The Bond Tower design team, working with code consultants, is developing an alternative solution that leverages the inherent 1.25-hour FRR of NLT floor assemblies. This approach suggests a pathway toward a new mid-rise category, making timber projects of seven or eight storeys more financially viable. Alongside a single-stair configuration, which can increase efficiency by reducing non-rentable floor area, these strategies point to a replicable model for affordable timber construction across Canada.
Learning Objectives
- Learn how NLT and prefabrication strategies can reduce cost, waste, and construction time, making timber more feasible in the Prairies.
- Explore structural detailing approaches that simplify connections and reduce cost, while addressing fire, durability, and acoustic performance in timber design.
- Examine how alternative solutions can improve the financial feasibility of 6–8 storey timber projects and support broader code updates across Canada.
