Feasibility of Point-Supported Mass Timber

Tall wood buildings offer tremendous potential for low-carbon, high-performance construction, but they also introduce a distinct set of challenges not typically encountered in conventional approaches. Design teams new to this form of construction may be unfamiliar with the systematic approach needed to enhance affordability and efficiency in these buildings.

Within the spectrum of structural solutions for mass timber, point-supported CLT is a compelling option for tall building applications. Teams must understand how to harness its unique benefits and navigate its limitations to unlock its full potential. When applied effectively, point-supported approaches can improve efficiency, reduce material usage, and unlock new pathways to cost-competitive tall timber construction.

Mass Timber Construction Success Checklist

Mass timber construction offers speed, sustainability, and design flexibility – but it also requires a higher level of coordination than traditional structural systems. Its prefabricated components and tight tolerances call for early planning, clear communication, and a shared understanding across the project team. Ensuring that all partners – including those less familiar with timber construction – are aligned on these unique requirements helps avoid costly delays and, more importantly, positions the team to fully capitalize on the benefits mass timber has to offer.

Exploring the Role of Mass Timber – Industrial Buildings and Warehouse Construction

The emerging use of mass timber in industrial buildings presents promising opportunities that are shaping the future of construction in this sector. As a sustainable and economically competitive alternative, mass timber is redefining industrial construction, a field traditionally dominated by prefabricated steel. An analysis of two cutting-edge projects in Sudbury, Ontario, highlights key advantages, including cost competitiveness, reduced embodied carbon, and aesthetic appeal. The insights from these two projects present stakeholders with helpful considerations and valuable strategies for integrating mass timber into future developments.

Design for Deconstruction in Light Wood Frame

The Guidebook of Design for deconstruction in Light Wood Frame presents a methodology for altering typical light wood frame assemblies so that they can be easily disassembled and the materials of the building can be reused. The province of BC and, more broadly, Canada, has relatively little infrastructure for recycling wood waste. In Vancouver alone, the construction, renovation, and demolition (CRD) sector produces about 1.7 million tonnes of waste per year.1 Of this, an estimated 30-60% is wood waste which is largely discarded in landfills. What little wood that is recycled is generally incinerated for waste-to-energy conversion or shredded for biomass. Deconstructing wood buildings and reusing the salvaged wood for new construction would extend the lifespan of the wood, add value and longevity to a valuable material, reduce GHG emissions and reduce the amount of new resources required for new construction projects. Despite the benefit of re-using wood, there are some barriers to deconstructing typical light wood frame buildings, including the use of irreversible fasteners, adhesives, spray foams, and liquid applied sealants. The presence of toxic materials such as asbestos and lead are also of concern when deconstructing a building. While use of toxic materials is now prohibited in new constructions the use of nails (particularly when applied with nail guns) and adhesives makes deconstruction very difficult if not impossible in some cases.2 This guidebook proposes a design for deconstruction system that addresses these remaining issues with simple modifications of typical light wood frame construction practices, allowing for both simple construction, solid performance, and easy deconstruction.

Wood Design & Building Magazine, vol 24, issue 96

Buildings that stand the test of time aren’t just durable—they are cherished. When we invest in quality materials and good design, we can create buildings that people connect with. As you’ll discover in this issue, many heavy timber warehouses and factories constructed in the early 1900s remain a vital part of our cities today—not because they still serve their original purpose, but because people valued them enough to adapt, restore, and reuse them, giving them a new purpose.

Fast forward a hundred years and resilient structures include many new forms. Modular construction, for example, has seen significant growth in recent years as this form of construction has transformed from a building method once considered inferior, into a method relied upon to deliver high-performance durable buildings.

Alongside our features on historic timber buildings and modular construction, this issue also highlights notable projects and emerging trends shaping today’s built environment. From innovative mass timber structures to forward-thinking design solutions, we explore how thoughtful craftsmanship and smart engineering continue to define the spaces we build—and the ones we keep.

Guide to Encapsulated Mass Timber Construction in the Ontario Building Code

The Guide to Encapsulated Mass Timber Construction in the Ontario Building Code – Second Edition is a comprehensive resource designed to help designers, code officials, and building professionals understand and apply the latest Ontario Building Code provisions for Encapsulated Mass Timber Construction (EMTC), effective January 1, 2025. Developed by the Canadian Wood Council / WoodWorks Ontario in collaboration with Morrison Hershfield (now Stantec), the guide explains the technical requirements, fire safety principles, and design considerations unique to EMTC, with clear references to relevant OBC articles. It covers everything from structural mass timber element specifications and encapsulation materials, to use and occupancy limits, mixed-use scenarios, and related provisions for structural design, environmental separation, and fire safety during construction. Intended to be read in conjunction with the Ontario Building Code, this is not a design guide, but rather a tool to distill complex regulations into practical, accessible information—equipping professionals to confidently design, review, and approve EMTC projects while ensuring compliance and optimizing performance.

Notice of Correction: A previous version of this document contained a small error on page 19. In this electronic version of the document (updated August 12, 2025) the 3rd major bullet of Section 5.1.1 has been corrected.

Guideline to Insuring Timber in Canada

To ensure that the financial investment of a construction project can be protected in the event of unexpected circumstances and project derailment, builders are required to obtain Builder’s Risk Insurance, also known as “Course of Construction” insurance.

In Canada, timber construction is utilized primarily in the residential market, with notable applications in low-rise industrial, institutional, and commercial buildings. The insurance rates for timber, classified as combustible construction, are generally much higher than that of non-combustible alternatives. Since timber applications have been consistent in the aforementioned markets, the associated insurance has not been substantial relative to overall project budget. However, with recent code changes and advancements in mass timber products, we can build larger and taller with timber than ever before, leading to changes in insurance rates as well.

The methodology for determining insurance rates for taller wood buildings is similar to that of low-rise builds. Combine that with the relatively new nature of these building typologies and the nuances of a stressed insurance market, we are seeing policies that are becoming a significant cost of the overall project budget.

This document is intended to support your timber builds by outlining practical steps to ensure that your application for insurance is favourable, and that your project is maximizing the potential to mitigate risk. Developed with the input of insurance stakeholders, we are confident that this insider insight will increase the success of your project.
