Construction Moisture Management of Mass Timber Buildings

Course Overview Mass timber buildings are transforming the way we build—but with new materials come new challenges. This session will explore how moisture risks in mass timber construction and how to take a proactive approach to moisture management. Participants will gain practical insights into effective protection strategies during the construction phase and learn how to develop a tailored moisture management plan to safeguard both the mass timber structure and project timelines. Learning Objectives Identify key moisture risks specific to mass timber construction and understand how they differ from traditional structural systems. Apply practical construction-phase moisture protection strategies that align with project sequencing, site conditions, and contractor workflows. Develop or evaluate a project-specific moisture management plan to protect mass timber elements, reduce delays, and ensure long-term durability. Course Video Speakers Bio David Stanton Associate, Senior Engineer – Building Enclosure RDH Building Science Inc. David is an Associate and Senior Building Science Engineer in RDH Building Science’s Toronto office. David’s exposure to mass timber projects started with the Brock Commons project in BC as a coop student and then with the Catalyst building in Spokane, WA—a 4-storey mass timber building for Eastern Washington University—when he started working full-time in the Building Science field. Since moving back to Toronto, David has continued to work on large scale mass timber projects, including the Lawson Center for Sustainability and the Academic Wood Tower projects at UofT.

Standardization of PWF as per CSA S406.
Emerging Solutions for Mass Timber in Healthcare
Resource Description Healthcare buildings are among the most complex and resource-intensive structures we design and, increasingly, they are being asked to do more. Modern hospitals not only need to support healing for patients and staff, but also to contribute to planetary health by reducing carbon emissions and addressing social and environmental determinants of wellbeing. To meet these goals, hospital design must evolve beyond the “squeezed and standardized” approach that has long defined it. Mass timber is emerging as a credible alternative to conventional systems for larger-scale, high-rise institutional buildings. Recent advancements in material science, manufacturing, engineering, and fire safety have made it possible to consider timber as a structural solution for complex facilities — including hospitals. Recognizing that innovation in healthcare design must be evidence-based, this collaborative study explores the feasibility of using mass timber for a 200+ bed acute care hospital. The multidisciplinary team — including KPMB Architects, PHSA (Provincial Health Services Authority of BC), Fast + Epp, Smith + Andersen, Resource Planning Group, CHM Fire, Hanscomb, AMB Planning, and EllisDon — developed and evaluated a detailed test design for a mass timber inpatient tower suited to the Canadian context. The study examined structure, cost, schedule, lifecycle carbon, code compliance, infection control, and biophilic design as part of a holistic approach to sustainable healthcare infrastructure. Learning Objectives Identify the key drivers that influence structural system selection in healthcare building design. Describe the opportunities, limitations, and specific considerations associated with using mass timber in hospital environments. Summarize findings from an in-progress feasibility study for a mass timber inpatient tower in a Canadian acute care setting. Evaluate the comparative schedule, cost, and lifecycle carbon outcomes identified in the study, and discuss implications for future healthcare projects. Course Video Speakers Bio Chris McQuillan, OAA, AIBC, FRAIC LEED AP Principal KPMB Architects Chris McQuillan, a registered architect and a distinguished Fellow of the RAIC, brings three decades of experience in planning, design and construction for healthcare and biomedical research. He has completed work across Canada, southeast Asia and in the Caribbean. In the healthcare sphere, his experience includes acute, rehabilitation and mental health treatment. Recently, Chris has designed major additions to Burnaby Hospital and Michael Garron Hospital in Toronto, a major expansion of the Halifax Infirmary, a new regional hospital in Corner Brook Newfoundland, a provincial specialty hospital for addictions and mental health in St John’s and strategic planning for the phased renovation of Royal Columbian Hospital here in Vancouver. A resident of Toronto, but active across Canada and beyond, Chris joined KPMB Architects in 2024 to propel the growth of the firm’s work in the healthcare sector. Chris’ focus in the design of healthcare facilities is to create healing architecture – for people, for our cities and for the planet. Mass timber must come to be viewed as an indispensable tool to help us achieve that goal. Juan J.
