On a special episode of the Construction Record podcast, digital media editor Warren Frey speaks with Hemsworth Architecture founder John Hemsworth and Structural Engineer Robert Malczyk about mass timber and other wood-based technologies used on two significant British Columbia projects.

Hemsworth and Malczyk explain how oN5, a four-storey office building located in Vancouver’s Mount Pleasant neighbourhood uses insulative cross-laminated timber (CLT) assemblies along with a damage-resistant seismic design built to a Passive House standard.

Malczyk and Hemsworth also speak about the Upper Skeena Recreation Centre, a heavy timber and wood-frame building that not only replaced a 44-year-old ice arena condemned due to safety concerns but became a new hub for the community. The project used skilled tradespersons from the community and locally available material. Building with wood meant construction could continue through the cold winter months.
