Innovative Strategies for Light-Frame Mid-Rise Buildings in High-Seismic Regions presents a detailed design example and practical guidance for engineers and builders responding to rising seismic demands on Canada’s West Coast. With the 2020 National Building Code of Canada significantly increasing seismic forces—particularly in Vancouver and Vancouver Island—conventional light-wood-frame (dimensional lumber) shearwall systems often no longer meet code requirements without costly additions.
This guide, prepared by WHM Structural Engineers for WoodWorks BC and the Canadian Wood Council, explores two high-capacity shearwall solutions: Mid+Std walls, a code-compliant adaptation of Midply construction that achieves roughly 50% greater capacity than standard walls without increasing wall length, and Double Nail walls, a research-based approach using double rows of edge nails to match Mid+Std strength. Combined with lightweight floor topping strategies, these systems enable six-storey light-frame buildings to remain viable and cost-competitive even on poor soils and in the highest seismic regions.
Cost analysis shows Mid+Std walls incur about a 30% framing cost increase over baseline, while Double Nail walls add about 20%, both more economical than doubling corridor wall lines. The publication includes complete design calculations, construction considerations, and conceptual connection details to help practitioners implement these strategies confidently.
This resource equips designers, contractors, and owners with practical, innovative approaches to maintain the competitiveness of light-frame wood construction while meeting the stringent seismic requirements of the latest building codes.
Industrialized offsite construction, also known as prefabricated or modular construction, is a construction method where building materials and components are manufactured and assembled offsite in factories before being transported to the project site for the final assembly. This approach can improve efficiency, reduce cost, and enhance quality compared to the traditional onsite construction. Industrialized offsite construction results from the reality of labour shortages, as well as the desire to automate manufacturing processes and shorten delivery schedules.
As the construction industry evolves and processes are becoming automated, FPInnovations has been working on industrialized offsite construction for the last decade to ensure that the Canadian wood industry maintains its competitiveness. Guided by a comprehensive roadmap developed by FPInnovations and its partners in 2019 to identify the knowledge gaps, FPInnovations accelerated in the past five years to address the impacts of manufacturing and construction changes across the value chain.
Inside the guide
This in-depth guide on offsite wood construction includes chapters on the following topics:
- Design process associated with offsite construction
- Offsite manufacturing process
- Lumber and engineered wood product portfolio available in Canada for offsite construction
- Performance of buildings manufactured offsite
- Essential activities outside of manufacturing plants for offsite construction
- Environmental impacts of offsite construction
September 15, 2025, Ottawa, ON: The Canadian Wood Council (CWC) welcomes the federal government’s launch of the Build Canada Homes (BCH) agency, announced yesterday by Prime Minister Mark Carney. Backed by a robust $13 billion investment and a plan to allocate federally owned lands for development, BCH will fast-track the delivery of affordable, sustainable housing nationwide.
