B.C.’s focus on heavy timber and mass wood construction is reshaping the construction industry, creating a new type of construction expertise, while also showing the private sector that mid and highrise wood structures can make economic sense.
“Since the beginning of this year, we are starting to see more interest from developers in these projects and the City of Vancouver is also interested in them,” said Eric Karsh, structural engineer and co-founder of Equilibrium Consulting Inc., a Vancouver firm that specializes in large timber, engineered structures. “We are now just beginning to see developers seriously consider eight-to-10 story solid wood buildings.”
The City of Vancouver is providing equivalencies such as reduced parking for the construction of wood buildings, which can translate into a plus for developers, he said, and there is the growing realization that the prefabrication approach offered by mass timber construction can expedite construction and reduce costs.
“We are developing details that show these buildings are cost efficient enough and developers are beginning to take notice,” he said.
That interest is a change from earlier attempts to kick-start private sector involvement. In 2012, wood advocate and architect Michael Green and Karsh published the Case for Tall Wood study, which advocated for wood highrises up to 20 stories and spoke with builders and developers regarding wood’s viability for mid-and highrise use.

Appalachian Hardwood Manufacturers, Inc. (AHMI), promoting the advantages of formaldehyde-free real, solid wood to public, are contrasting its natural qualities with the unsafe laminate flooring that had gotten Lumber Liquidators into trouble with consumers.
“Discount flooring companies selling imported laminate floors have been providing customers with products that can carry seven to twenty times the base amount of carcinogenic formaldehyde allowed by the EPA,” says the AHMI. “At these levels, formaldehyde secretes from the flooring and into the home’s air, becoming a high-level health risk, especially for children and pets who are most susceptible to its effects. Carcinogenic formaldehyde found in artificial wood has been linked to lung and nasal cancer, nausea, asthma, and other severe respiratory issues.”
Wood industry trade groups, including furniture and cabinetry makers, have been trying to separate their goods from the products made in China that contained high levels of formaldehyde. The Kitchen Cabinet Makers Association issued a statement last week saying that there is no risk of exposure to formaldehyde in cabinets that receive its Environmental Stewardship Program seal, because its program requires that engineered wood used in it must be CARB Compliant.
Other groups have questioned the validity of testing methods used to detect formaldehyde in wood products – such as flooring sold by online retailer Wayfair – tests that deconstruct the multi-layered sandwich that makes up laminate flooring. The Hardwood Plywood and Veneer Association estimates that “finishes of paint, lacquer, sealants, laminate, plastic or other material” reduce formaldehyde emissions of the underlying raw board by 90 percent.
