Of all the recent advances in tall-building construction, perhaps the most counterintuitive is the nascent move toward wood as the primary material for high-rise towers. Yes, wood construction is environmentally friendly. It comes from trees that trap atmospheric carbon dioxide (a gas that, most scientists say, is the cause of manmade climate change); it’s a renewable resource; and, according to experts, the manufacturing process for wooden building products emits less carbon than that for any other material used in construction.
But, wood isn’t as strong as steel and concrete, right? And, an even bigger concern: wood burns. It’s not hard to imagine a giant timber tower being quickly devoured by flames. It’s an image that’s hard to shake.
A recent article posted on the website Fast Company, however, may put these fears to rest. In it, author Jesus Diaz tells of Mjøstårnet, an 18-story, 265-ft.-tall project being built in Brumunddal, Norway, that will soon be the world’s tallest all-wood building. With the help of a five-part mini-documentary produced by construction company Moelven, we learn that the latest engineered-wood building materials are both strong and fire-resistant. We also learn of innovative construction techniques being employed on this jobsite.
It’s not likely that wood will replace steel and concrete in every future high-rise project. But, it does appear to be a viable option for many types of buildings.
