There are approximately 350 to 400 prefabricated building manufacturers in Canada and there is potential for this to increase. Manufacturing is carried out in controlled environments, but assembly and connection on the construction site is problematic and there is a need for connections that are economical, easy to install and reliable.
Although there are some proprietary connections available, they can be expensive, difficult to install or their long-term performance is in doubt. Therefore, many smaller prefabricated manufacturers still rely on traditional connection systems (i.e., anchor bolts, nails) to connect the various subsystems on-site.
- explore potential improvements in existing connection systems used in assembling prefabricated wall panels (wall-to-wall, wall-to-foundation and wall-to-roof), which could eliminate current design and construction difficulties and improve the connection performance.
