Summary
Overall moisture management during construction has become increasingly important due to the increase in building height and area, which potentially prolongs the exposure to inclement weather, and the overall increase in speed of construction, which may not allow adequate time for drying to occur. This report provides guidelines and relevant information about on-site moisture management practices that can be adapted to suit a range of wood construction projects...

Summary
The study assesses the current state of the prefabrication industry in Canada and identifies key challenges and potential market opportunities in the sector for the increased use of mass timber. This analysis of the current state of the industry examines all forms of prefabrication, with a focus on wood (light wood frame and mass timber) where possible. A more detailed analysis focuses on future mass timber market opportunities in Canada and globally, including prefabricated timber building elements (i.e. structural components, retrofit components, etc.) and building typologies. Recommendations will inform policy decisions and other efforts required to support the further development and adoption of prefabricated timber buildings in Canada.

Summary
This project evaluates off-site solid timber production processes in the international solid timber industry. The Solid Timber Construction (STC) projects documented herein provide a test bed to evaluate project performance metrics attributed to off-site construction. This study also evaluates the contingent qualitative environmental, organizational and technological contextual factors related to STC. The study therefore: Investigates and documents STC projects to identify successful performance metric parameters: economics, schedule, scope, quality, risk, and worker safety. Compares this data to traditional site built construction to determine the estimated added value or negative impact of STC. Identifies qualitative contextual parameters including environment, organization and technology for successfully developing STC methods; Creates a model for data gathering for STC stakeholders to report their own performance parameters and thereby create a robust database of off-site projects in the future. Synthesizes holistic best processes and practices guide for the industry looking to engage in STC work.

Summary
On tall wood buildings, mass timber elements including CLT, NLT, glulam, and other engineered components absolutely need to be protected from excessive wetting during construction. This requirement precludes the use of many conventional cladding systems unless the building is fully hoarded during construction. The building enclosure and façade of UBC Tallwood House consists of an innovative prefabricated steel stud rainscreen curtain-wall assembly that is pre-insulated, pre-clad, and has factory installed windows. Design of connections and air and water sealing of panel joints and interfaces was carefully considered given the tall wood structure they were designed to protect. While steel studs were utilized in the panelized structure, feasible curtain-wall designs were also developed and prototyped for wood-framing, CLT, and precast concrete as part of the project. Looking ahead, there will continue to be innovation in design and construction of fast and durable facades for taller wood buildings. New prefabricated panel designs incorporating CLT panels and connection technologies from unitized curtainwall systems are already being developed for the “next tallest” wood buildings in North America.
