Technical Guide for the Design
and Construction of Tall Wood
Buildings in Canada
NEWBuildS Workshop
Vancouver, May 2015
Erol Karacabeyli and Conroy Lum
Background – Tall wood buildings were
always there!
 ~A century ago: Brick and Beam Buildings
up to 9 storeys constructed in Canada
 Seismic Upgrading in Vancouver’s Gastown
(1980s, Karacabeyli and Wong)
 NewBuildS project (Carleton, Kruszelnicki)
reveals the code story
 FPI study (Koo) shows why these buildings
are still serving their clients

Technical Guide for the Design and
Construction of Tall Wood Buildings
 Comprehensive document on this topic
prepared by team of 85 researchers, design
engineers, architects and code officials
▫ Peer-reviewed
 Helps pushing the boundaries of
wood construction by using
innovative hybrid solutions
 Funded by Natural Resources
Canada (NRCan)

 Consistent with the design objectives and
functional statements of the 2010 NBCC
 Performance-based philosophy
followed where possible
 Aimed at defining a new
type of construction…

Conclusion
 Given current knowledge on mass timber
construction, development of sound
alternative solutions for TWBs is feasible
 FPI Technical Design Guide provides
guidelines for developing such alternative
solutions
