Wood, or more specifically mass timber construction, is probably not the first thing that comes to mind when thinking of proptech. Yet, as much as any algorithm, mass timber engineering is being used increasingly as a technological solution in the construction industry, particularly in low- to mid-rise buildings. “I would definitely put mass timber under the umbrella of construction technology, and I think all construction technology fits under proptech,” said Henry D’Esposito, construction research lead for JLL. …Although only included in a tiny percentage of construction in the U.S. right now, mass timber is growing as an alternative to steel and concrete construction in projects up to 18 floors, D’Esposito said. “From a national perspective it’s growing faster than overall construction. …Two reasons for that growth are mass timber’s sustainability and aesthetics.
