Envisioned as the office headquarters for the future lead-tenant, 2150 Keith Drive’s first design mandate was the use of mass timber. The design team was looking for ways to incorporate the patterns of nature into a delicately detailed exposed mass timber superstructure with a powerful architectural façade for the prominent Vancouver site.

Through much collaboration with the DIALOG architectural team, Fast + Epp developed a perimeter timber braced frame system that creates a striking façade expression and eliminates the need for conventional cast-in place concrete cores. The perimeter timber braced frames are paired with four discrete internal cross laminated timber (CLT) shearwalls. Once complete, this should be the tallest timber braced frame in North America.

Having learned that integrated service distribution is key to the successful architectural expression of a mass timber ceilings, Fast + Epp also developed a bottom-flush interior girder system, using custom steel members. This system creates a ‘flat plate’ ceiling, perfect for mechanical and electrical service routing.

The timber braced frame and cross laminated timber shearwall systems are currently undergoing small-scale and full-scale testing at the University of Alberta and the University of Queens, which will provide invaluable engineering data back to the design community for future tall wood projects.

The ‘all-timber’ system has been designed as a kit-of-parts prefabricated structure to facilitate rapid construction erection. Fast + Epp considers this a pioneering project that will continue to inform the design and construction movement towards mass timber.
