2 Program Education Credit Information The Canadian Wood Council is a Registered Provider with the American Institute of Architects. This course meets Continuing Education System requirements for one Learning Unit. Credit earned on completion of this program will be reported to CES Records for AIA members who provided their member number during the online registration. This course also qualifies as Structured Learning with OAA. Certificates of Completion for OAA members, and anyone else who indicated they wanted a certificate, will be ed after the event to those who requested them during the registration process. We will also report participation to the Engineering Institute of Canada on behalf of any engineers who requested their participation be recorded. This program is registered with the AIA/CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product. The same is true for the OAA and EIC. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation. : EASTERN CANADA'S FIRST 6-STOREY CLT BUILDING PRESENTATION SUMMARY PRODUCTS AND FABRICATION NORDICLAM (GLULAM) NORDIC DECKING XLAM (CROSS LAMINATED TIMBER) OVERVIEW CHALLENGES IN DESIGN STRUCTURE AND DETAILS PREFABRICATION ARCHITECTURAL DETAILS CONCLUSION QUESTIONS 2
