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.

Halsa 230 Royal York: Ontario’s Tallest Mass Timber Residential Building
Course Overview Halsa 230 Royal York is setting new standards as Toronto’s pioneering 9-storey prefabricated mass timber rental building, demonstrating the viability of carbon-neutral communities within Toronto’s Right of Way zoning. Through a case study of the building, this session will present the advantages of integrated design and prefabricated mass timber building systems components. Learning Objectives Explain the integrated design and prefabrication strategies used in mass timber residential construction: Learners will be able to describe how collaborative design, advanced manufacturing, and prefabricated building systems contribute to project efficiency, quality, and scalability. Analyze the technical features and performance benefits of mass timber floor cassettes and curtain wall systems: Learners will understand the structural, acoustic, fire resistance, and thermal properties of the building’s mass timber components, and how these features address common challenges in high-rise construction. Evaluate the sustainability, regulatory, and operational considerations in developing carbon-neutral mass timber buildings: Learners will assess how material sourcing, certification, lifecycle carbon analysis, and code compliance shape the viability and impact of mass timber projects in urban environments.
