3:30 pm - 5:00 pmPanelization & off-site Construction methods - Waterhouse 5
OSWA’s members, who are over 100 strong, are the experts in the manufacturing of off-site wood components. Roof and floor trusses and EWP products have long been the staple of the industry. But it is clear that the entire structure of wood buildings, including walls, can be built more efficiently off-site and merely assembled onsite. This can take the form of flat pack delivery or modular / volumetric methods. In either case this type of construction achieves many positive results that the “stick-built” traditional methods are not able to deliver. The builder can save money with a faster build time, reduction of material waste, reduced labour requirements and improved project coordination. Our presentation will explore how the construction industry can see the efficiency improvements that virtually every other industry has seen over the past few decades with the increased use of panelization & off-site construction methods.
